Slewing bearing fault repair method

Construction Machinery Stainless steel slewing bearing material porosity due or mezzanine, swim raceway hardened layer hardness, depth manufacturing quality problems such as uneven or

Some external reasons, resulting in hardened raceway spalling or broken tooth ring gear, equipment will not work.
For raceway delamination, we must first make the right judgments. Delamination occurs, generally the external hard to see. According to our experience,

In the following cases, indicating that there is delamination raceway: Host load rotates, the raceway has "slightly - slightly" abnormal sound, rotation speed

Uneven or an azimuth slowed significantly and accompanied by a slight vibration; rotary current motor temperature is too high or too large; Rotary

Motor and hydraulic coupling or coupling pushed up bad habits such as keyways.
Delamination occurs, it must be repaired. Otherwise delamination area will be expanded to the entire slewing bearing scrap.
Repair method is: first slewing roller or ball inside out, so that separation of inner and outer rings; reuse gasoline to clean raceway

Clean; Then grinder (wheel) Microsoft Corporation needle carefully peel layer surrounding area has been hardened cracks generated

Layer rubbed off, the bottom layer will peel polished; raceway required for welding and cutting torch at the preheated by using carbon steel welding rod (electrode before

Be dried and used as baking), to make the solder layer just above the raceway surface 1-2mm; deeper if delamination or larger, should be divided

Layer fragmentation welding, do not make the base material caused by high temperature deformation; This avoids rapid cooling weld cracking, immediately after welding

Insulation measures taken so that he gradually cooled. After cooling grinder grind welding layer, making it slightly above the raceway surface, oil stone

Metallographic grinding or welding layer gradually emery cloth table it with the normal surface raceway highly consistent with the corresponding original curvature model testing,

Until the qualifying date; clean with gasoline raceway and roller (ball) coated with grease, integrally assembled to complete.
Facilitation by the above method of tower cranes and other equipment slewing ring raceway, after long-term use is working properly.
Swing ring gear teeth broken reason may be that the tooth base material quality cast segment (if trachoma, sandwich and other defects, the teeth

Round bending effect significantly weakened); process of using tooth contact inserts of hard objects such as stones or reinforced, so that local bending tooth

Stress increases fracture.
Repair method is a local repair welding or tipped, local welding method is: first damaged parts of the residual matrix crack

Rubbed with a hand wheel, gasoline (oil) clean; welding torch used in this part of the warm-up, when it reaches a certain temperature, the use of

Carbon steel welding rod damaged areas in the teeth of the toothed push welding prototype, making it higher than the party Tooth 1-2mm; send experienced

Machine repair fitter, in accordance with toothed model testing, until tooth compliance requirement.
When the rotary ring gear of an entire tooth is damaged, cut along the tooth root, tooth root and then file into a certain shape. Again in the same

Waste storage ring gear cut a tooth, processed into the appropriate shape with the base material, into the slot, with the tooth template snaps into place.

In order to ensure the consistency of pitch, and added with double wire clamp after tightening the teeth surrounded by low-carbon steel welding. Finally, rasp and other working

Shuhei with the welds to ensure stability augmentation to tooth contact.

The method of solving slewing noise

Slewing bearing noise common to have two kinds of dust acoustic sound solutions and scars are as follows:
        (1) The method for controlling dust acoustic
      Slewing dust and other foreign matter inside, aperiodic vibrations occur, the so-called dust acoustic, vibration and noise of the size of its

Uncertain, and with or without.
   Dust acoustic control method: Improve slewing ring / turntable bearing cleaning method, before installing the bearings, shaft, housing bore and

Clean all the parts match the stringent cleaning; removal of foreign bodies within the lubricant; improve the bearing seals; avoid the use of materials or impure

A foreign body embedded plastic cage.
         (2) The method for controlling the sound wounds
    If slewing ring rolling surface cracks, dents or corrosion occurs as riveting as periodic vibration and rivets

Noise, its period may be fixed but most of the rotation speed into a certain correspondence between the scar occurs on the channel continuously, the wound

Marks on the ball when the time is now hidden, and this noise with the installation and lubrication conditions there are some changes.
   Such noise control method: When installing not knock the bearing, the bearing and shaft assembly into the bearing block and then to prevent

Bearing mounted oblique; inventory prevent bearing corrosion and transportation to prevent shock and vibration; using high viscosity grease.

       (3) Lubrication noise caused by factors and countermeasures
      Lubricant selection errors, lack of lubricant or the occurrence of aging sclerosis, can cause slewing ring / turntable bearings generate vibration

Action and noise, and this noise does not necessarily rule. In this case, only the selection of a suitable lubricant to adjust its

Amount of lubricant to extend lubricant life and reasonably determine the replacement cycle.
       (4) noise associated with the host and Countermeasures
  This noise is not simply caused by a bearing, and thus to find a single reason from the bearing area is invalid, plus a comprehensive response to the host

, Notes, if necessary, to improve the performance of the host. Now the main narrative common motor beeps and rack resonant sound.
     A motor beeps and Countermeasures
      Axial vibration of the motor shaft will cause a lot of high-frequency noise - beep, its frequency and the same axial vibration frequency,

Can be constant can be varied. Beep way to prevent axial vibration and prevent the same way.
    B bearing frame resonant sound and Countermeasures
      Quality Department aforementioned outer axial vibration inherent in the axial bearing frame bending natural vibration, is called a resonant sound

The noise will follow. Increase the preload method can improve the quality of the outer ring the natural frequency of the axial line, destruction resonance condition,

Reduce noise.

How to prevent wheel bearing raceway quenching crack

 Slewing bearing (wheel bearing) hardened raceways need this procedure, improving by quenching wheel bearing raceway hardness increase

Slewing causes shaking at work

 There are a lot of staff are at work in the reaction slewing process will shake problems, so the staff is very worried

Heart, fearing the process of working households in any danger. Orson Xuzhou Slewing bearing  maintenance personnel, in fact, slewing

At work and have a lot of swing problems and the reasons for, as long as careful check and troubleshoot problems shaking, everyone

Can rest assured. Well, the reason slewing ring shake, what does?

First, to check the screws are loose, if loose should be tightening. Second, in checking whether the work overload, super-

Working out can also affect the slewing ring. Again we have to look whether the supporting steel structure slewing ring deformation, if the deformation

Issues should be timely exchange and steel supporting force to achieve 14 times. These reasons that led slewing at work

There are shaking problem, if you exclude these reasons are still shaking after going to a local repair parts repair, so as to protect the workers

The security for the

Slewing ring in what environments

   Slewing bearing ring can be used in different areas, so that it can adapt to different working environments. Slewing generally at minus 300 degrees to 700 degrees, in particular to adapt to the harsh environment where the ocean can also be used on a ship in the ocean, we all know that the environment is harsh, often encounter rain, ice, etc. problem, slewing ring can also work. While slewing also used in aviation, aerospace pressure, are generally required to choose light-weight material, and slewing ring can withstand this pressure, and also to work properly. While slewing in a variety of different environments, but we should also do maintenance work, improve work life.

Slewing ring bearing the meaning and structure

   In industry sometimes hear slewing Roller bearing, slewing ring bearings sometimes hear, in fact, is a slewing bearing slewing ring, is a short, its just the same as used in the slewing ring and able to withstand comprehensive load bearing. Slewing ring bearings is to have the worm, slewing ring, shell, motor and other components form while slewing will be divided into toothed and toothless, toothed slewing will have outer, inner teeth, sealing tape, glib, no teeth slewing there outer ring, orifice, isolation belt and other parts. So toothed and toothless slewing ring in the structure is not the same.

Slewing security

   Whether in any industry, or any mechanical parts, we are most concerned about is the safety issue. Especially slewing not only can be used in machinery and equipment, also used in military, aviation, playground, so that the security of slewing ring is very important.
Orson Xuzhou Slewing introduction: We do not worry about the safety of Slewing bearing, slewing ring in the machinery because there is a significant role, so the production of slewing ring has strict requirements. Inspections in the slewing ring is checked through a number of technical personnel, qualified to sell the factory. If you still worried about the safety of slewing ring, everyone at the time of purchase can also choose reputable manufacturers

What slewing bad heat problem

Slewing ring in the production process, heat treatment is very important, if not well controlled temperature will directly affect the product problems. Heat treatment technology would be so handled problem then?
If the heat treatment temperature is too high will reduce the process of slewing toughness and the fight against sexual. Temperature is too low, there will be cause slewing crack problems, low wear resistance, it will directly affect the life issues. If the heat treatment handled properly, can lead slewing Backing bearings surface decarburization, deformation and other issues, so that in the production of slewing heat treatment process is very important

What kind commonly used in machinery slewing

 Slewing bearing are often used in machinery and equipment, often used in cranes, excavators, mining machinery, concrete pumps and other various industries. The slewing ring, there are many types of different types have different functions and uses. Under normal circumstances will often use mechanical equipment: four point contact slewing bearing, single-row four point contact ball slewing bearing, three-row roller slewing ring and so on. These models slewing often be used.

How about slewing

 Slewing often used in different industries, although widely used, but we still want to know how to slewing, okay?
Orson Xuzhou Slewing description: slewing ring has a high quality of protection, roller bearing  slewing ring to withstand mechanical steering force, so strict rules slewing ring must reach a certain size, if any, does not reach the required product is not for sale . While slewing start small friction coefficient, consumption is small, can be applied in hot or cold places, and there are very high hardness.

The magnetic bearings skf bearing information presentation

  Magnetic Roller bearing are supported by magnetic force load bearing or suspended form a rotor. This bearing has developed rapidly in recent years, particularly in the high-speed, low friction, high (low) temperature and vacuum environment applications. Magnetic bearings compared with other forms of support has its unique advantages, promising.
Several typical magnetic bearings
1. Permanent magnet-type magnetic bearing
Permanent magnet-type magnetic bearing is made ​​by the permanent magnets can be made into various shapes. Load bearing capacity and stiffness depends on the type of permanent magnet material, pole shape, area, thickness and configuration, the bearing clearance, and the size of the portion of soft magnetic steel. Theoretical calculation of these bearings is very difficult, often using "experiment similar method" design. Is determined experimentally several typical bearing structure, measure its carrying capacity, stiffness. Take the same design as long as the new bearing material, the structure and dimensions according to the ratio that the performance can be calculated in proportion to such bearing capacity of the bearing is proportional to the square of the feature size and so on.
2. AC excitation type passive magnetic bearing
Thrust Slewing bearing  are usually combined in pairs, each bearing is an electromagnet. Core geometry is generally E-shaped, U-shaped or annular. Tuning mode of serial and parallel two kinds.

  We are mainly looking Baidu, Baidu search from Shanghai skf Roller bearing , left to promote a three, right there eight. Search results total there are 1.6 million. Many pages are in front of the official website, which is no paging existence.

This can be said that a typical search of less, but the competition is a lot of examples of it. However, in Shanghai skf bearing the word search volume rarely, and some links between competitors and concerns. So in fact, the role is not too much.

Search skf bearing the word on the left there eight promotional advertising. Instead of three, the search volume of about 3.5 million, which can be considered the number of lower-middle, but I think a lot of bearing the word basic website will be used, the official website piles, competition is very much.

Further cut backing bearings  the word, the promotion did not change the number of search volume to 6.5 million. The same high degree of competition. Although the Web site optimization is on the one hand, in fact, website promotion is also crucial. Such as the first Shanghai skf bearing the word, although the search volume is not high. But a website can make up the word is countless, a good website is one such an accumulation brought about by a user. Slowly formed, you want quick success is not desirable.

Skf bearing measurement microphone Introduction

  Measuring instruments Slewing bearing noise. King microphone for measuring the channel indispensable components, the sound pressure will change with the corresponding change in the voltage. Microphone should have a uniform frequency characteristic; sufficient sensitivity and stability, and is independent of temperature, atmospheric pressure and the time of use; the entire dynamic range of the measured channel low inherent noise, nonlinear distortion. Awarded the same mark dirty (t'ocTl 37N-73) provides for the measurement microphone with 56 technical requirements.

     To test was, capacitor type can be used and electric microphone. Piezoelectric microphone, since the frequency characteristic is not satisfactory, are rarely used measuring instruments bearing noise.

Spherical Plain Bearings

 Slewing bearing are widely used in hydraulic engineering, metal forming machine tools, engineering machinery, automation equipment, automotive shock absorbers, irrigation machinery and other industries. Introduction and classification of joint bearing joint bearing is spherical plain bearings, the basic model is made with a sliding spherical contact surface the inner and outer components. According to its structure and type, can bear radial load, axial load, or radial, axial joint load acting simultaneously. Because of the spherical plain bearings sliding contact area, tilt angle is large, but also because most of the bearings taken a special treatment process methods, such as surface phosphating, zinc, chrome or outer sliding surface lining, insert pads, spraying. Therefore, greater load capacity and impact resistance, and has anti-corrosion, abrasion, self-aligning, self-lubricating lubrication better or no lubrication contaminating features, even if the installation dislocation can also work. Therefore, joint bearings are widely used for slower swing motion, tilt and rotation movement

Reasonable selection of spindle bearings

1 precision angular contact ball bearings
In the above several Roller bearing to precision angular contact ball bearings (Figure 1) is the most widely used. Angular contact ball bearings rolling the ball, because it is a point contact (distinguished from roller bearing line contact), they are able to provide higher speeds, smaller heat and higher rotational accuracy. In some applications where high-speed spindle, but also ceramic balls (typically Si3N4 or Al2O3) hybrid bearings. With the traditional full hardenability ball compared the characteristics of the ceramic ball material itself gives the ceramic ball bearings with high stiffness, high speed, high temperature, long life, high-end customers in order to meet the demand for machine tool bearings.
Precision angular contact ball bearings
For angular contact ball Slewing bearing contact angle, the more popular is the contact angle of 15 and 25; usually a contact angle of 15 has a relatively high speed performance, while 25 of the contact angle with high axial load carrying capacity. Since the choice of preloaded angular contact ball bearings for precision applications is very large, as in high load, high rigidity of the occasion, the general will choose medium or heavy bearing preload; And for some high-speed, high-precision applications, early in the bearing selection, you need to pay attention to choose the right preload. Preload is generally divided into light, medium and heavy-duty three kinds, general light preload more common. In order to facilitate the customer's use of the world's major bearing manufacturers generally available and add pre-ground bearing face of the bearing preload, which is commonly referred to as universal matching precision angular contact ball bearings form. These bearings are removed from the customer preload adjustment, thus saving installation time.

Bearing industry trends

"Machine Components, basic manufacturing processes and basic materials industry," second five "development plan" clearly will drive strong radiation effect large high-speed, precision, heavy duty bearings and other machine parts as a "second five" development focus industry, in order to improve performance, reliability and longevity as the main direction, and strive to reach or approach international advanced level. "Planning" also pointed out that, in terms of policy support, 2015, bearing industry sales will reach 222 billion yuan, an average annual growth rate of the industry will be between 12% -15%, of which high-speed, precision, heavy-duty, high-end Bearing the growth rate will be faster. Crossed roller bearings
   Backing bearings is an important equipment manufacturing industry, the key infrastructure components, cross-tapered roller bearing directly determines the major equipment and host product performance, quality and reliability, as the equipment manufacturing "heart" of parts. After years of development, China's bearing industry has formed a considerable scale, national bearing industry in 2010 output value of about 130 billion yuan, ranking third in the world. Despite the scale of China's bearing industry has been very large, but most are concentrated in the low end, while at the high end bearing manufacturing, China and developed countries, there is still a considerable gap. Thin section crossed roller bearing China Bearing Industry Association Secretary-General Wang Quanqing has made it clear that China still can not keep up the pace of development of high-end bearings host of development. For example, China has mastered with independent intellectual property rights of high-speed EMU technology, but also ancillary bearing basic dependence on imports. Currently, the domestic production of high-speed bearings bearing mostly only meet 150 km -180 km of the train, while the United States and Europe to meet the high-speed rail bearing speed of 350 km -400 km train needs, so that the current domestic more than 200 kilometers per hour EMU supporting The basic dependence on expensive high-speed rail bearings imported.
    Based on the facts behind our high-end bearings, "plan" clearly will give full play to the guiding role of industrial policy, improve industry access threshold to curb redundant construction; thrust cylindrical roller bearings, including bearings industry, including giving "three bases" Industry fiscal policy to support the implementation of key components and raw materials imported duty-free policy; study and formulate encourage users to adopt the "three bases" of new products and new technology policy.
