china bearings of grease to make it play a role in rust

Before removing wheels, wheel maintenance should do the preparatory work, the car parked and set up axles, in order to ensure the maintenance of security operations. (1) Remove the hub shaft head decorative cover, dust cover; (2) Remove the wheel nuts and tires, be careful not to bruise the tire bolt threads. If disc brakes, the brake should be removed, and then used pliers to remove the lock ring or locking pin. (3) china bearings with a special tool to remove the wheel hub; (4) scrape bearings, journal and hub cavity of the old grease, cleaning wheel china bearings and journal with detergent and wipe dry with a cloth, wipe with a cloth wheels last cavity. (5) Check the wheel bearings and bearing races, found cracks, fatigue spalling and loose roller bearings and other phenomena, replace bearings. If you find pitting on the bearing race, it should replace the bearings. When cope with the situation (6) Check the bearing bore and the journal, with the gap should not exceed 0.1Omm measuring journal, should be in the upper and lower parts of the vertical ground (where the largest wear parts) measurements. slim bearings used with the gap exceeds the limit, replace the bearing, so back to normal with the gap. Burr is not allowed to play, pitting the journal to narrow the gap. (7) Upon completion of all parts meet the requirements, the inner bearing grease after release hub. When (8) grease the bearing cavity attention should be squeezed into the bearing grease until grease to date to emerge from the other side of the bearing. In the hub and shaft cranial cavity Apply a thin layer of grease to make it play a role in rust. Note that the hub cavity do not apply too much grease, otherwise it will affect the cooling and braking. (9) the hub and the outer bearing back onto the journal, hand-axis head adjustment nut, and then use the required shaft torque wrench to tighten the adjustment nut. After tightening the nut, Taper bearing turn the wheel a few times to be around to see the bearing installation; on the other hand, by turning the bearing and seat properly fit. At this time bearing tightness appropriate wheels to rotate freely and not feel the axial clearance. (10) Finally, in order to install the locking plate, fixing nut, tires, china bearings dust cover and decorative cover and other parts. (11) wheel bearings adjusted, with some mileage (about 1Okm), stop and check for swab touch wheel temperature, if fever, is caused by the bearing adjustment too tight, should be re-adjusted appropriately relaxed bearing tightness.

Luoyang bearing the use of the environment

Luoyang bearing the use of the environment: according to the size, accuracy of location and conditions of use and environmental conditions, with the right bearing is the premise to ensure the bearing life and reliability of the. 1, allowing speed: correct installation, Luoyang bearing lubrication good environment, allowing for 0.3-0.5 times bearing limit speed. Under normal circumstances, the limit of 0.2 times the speed of the most desirable. 2, using the site: combined load of Luoyang bearing for radial and axial radial load to bear mainly on, precision bearings usually with two sets of angular contact ball bearings are used, primarily in the car front and rear wheel, a driving bevel gear, gear, reducer and other transmission parts. 3, allow the tilt angle: tapered roller bearings are generally not allowed to tilt axis relative shell hole, such as tilt, less than 2'. 4, slim bearings allow the temperature: under normal load, and the lubricant has the advantages of high temperature resistance performance, and full lubrication conditions, allowed to work in -30 ℃ -150 ℃ temperature generally angular contact ball bearing.

Tapered roller bearings matters needing attention

High speed rotating note: Tapered roller bearings at high speed, especially the speed of approach or exceed the speed limit size table records, should pay attention to the following matters: (1) tapered bearing supplier the use of precision bearing (2) analysis of bearing internal clearance (bearing internal clearance considering temperature rise reduction) (3) the analysis material of cage type (for high speed rotation, Tapered roller bearings suitable for copper alloy or phenolic resin cutting holder. Crossed-roller-bearing is also suitable for synthetic resin forming high-speed rotating cage) (4) analysis of lubrication (which is suitable for lubrication of high speed rotating, spray lubrication, oil mist lubrication and oil air lubrication, lubrication).

The speed limit of china bearings

Angular china bearings speed increased restrictions is mainly because of the angular contact ball bearing friction fever induced by internal temperature, when the speed reaches a certain value, china bearings due to burn and cause cannot continue rotating angular contact ball bearing. The speed limit of angular contact ball bearing is the frictional heating does not cause burns and continuous rotation of the boundary values. Therefore, angular contact ball bearing limit speed depends on the china bearings type, size and accuracy and lubrication, lubricant quality, cage and type of material, Slewing Bearing loading conditions and other factors. All kinds of angular contact ball bearings with grease lubrication and oil lubrication (oil bath lubrication) speed limit when contained in the angular contact ball bearing size table, its numerical representation standards for the design of the angular contact ball bearing under general loading conditions limits when the rotation speed value.

Wheel Luoyang bearing code representation

Bearing Code by simply code and post code form.Fundamental code is divided into three parts, Luoyang bearing the first part of the code structure types and drive types, central rolling diameter (for more than two rows of rolling element bearings for maximum rolling element diameter), Luoyang bearing heart weight rear rolling circle diameter (for two rows above the rolling bearing body weight for maximum heart rolling circle diameter) 1, structure type code according to the rules in Table 1. 01 four-point contact ball bearings; 02 double Reducing ball bearings; 11 interspersed cylindrical roller bearings; 13 with three-row cylindrical roller bearings. 2, Slewing Bearing transmission type code according to the rules in Table 2. 0 Toothless; an outer involute cylindrical gear teeth smaller modulus; 2 Luoyang bearing involute cylindrical gear outer teeth larger modulus; 3 involute cylindrical gear teeth within a smaller modulus; 4 involute cylindrical gears inner teeth larger modulus. 3, the fundamental rules of the code compiled Fundamental code layout, the structure type code and transmission type code writing for the front, middle and rear with between.
