large deformation proportion remains high specification products

To break this bottleneck as soon as possible , last March , the company set up a special project team bearing the main research content is in large thin-walled bearing outer heat treatment deformation control . First, in the application of the device , the project team presented with a new furnace to replace the rollers mesh belt furnace . Since the former is heated by radiation , the temperature can be precisely controlled , better Crossed-roller-bearing  heating uniformity , can greatly reduce the amount of deformation . Meanwhile, the roll bar with nitrogen and propane furnaces for protective atmosphere , allowing the product through appropriate oxidation to achieve the desired hardness , to meet different customer requirements.
Roller furnace new production line put into operation after a period of time , the question came up : the  into the furnace to Compound baskets, large deformation proportion remains high specification products . The project team developed the implementation Tapered bearing plan of the project, the schedule lists : the first step small batch processing, such as the promotion of a wide range of process maturity and then , at the same time according to the time schedule, to reduce the amount of deformation also put forward a clear indicator. Through several experiments , on the one hand , optimizing layouts, eventually completely without baskets directly to the placed on the stove , so that a single into the furnace to increase the amount of productivity also will increase ; on the other hand , the project team by replacing the quenching oil, according to the product type stirrer speed and time settings , oil quenching is more evenly distributed in the surface, to ensure the hardness after quenching and qualified to achieve the required in order to better control the amount of deformation . After these improvements reflect subsequent grinding staff is very good . They say that good quality new processing technology ,

Tapered roller bearings Machine tools-ring Ball Features

Machine tools-ring Ball Features:
High dust and grease sealing performance of both performance-ring seal with a specially designed ball screw, the outer seal lip blocking external foreign invasion, grease the inside of the sealing lip to prevent internal leakage. Compared with the general screw screw-ring "to reduce the amount of foreign matter 1/30 or less, grease Tapered bearing sealing performance and increased 3 times, in order to achieve a long tool life, reduce environmental pollution.
Low torque contact seals: Ball-ring seal lip shape using the most optimal design, and the use of special resin material, low friction contact with the screw shaft, simultaneously with high sealing performance and low torque performance, thereby high-speed and high-precision machine tools to meet the requirements.
In 2005 developed a high dust seals, laser processing machines are widely used in machine tools, woodworking Stainless steel slewing bearing machines for use in harsh environments. 2007 based on this technology to develop a grease seal ring and the injection molding machine market has been widely praised. With this sealing technology further developed the machine with the ring Ball", high performance dust and grease sealing performance skills, low torque, long life machine tool, machine tools to reduce environmental pollution ring ball screw "as the latest high-speed ball screw machine tools, will start selling in April 2011, is expected in 2013 with a high-speed ball screw machine total sales will reach 50 billion yen.

Tapered roller bearings the semi-finished and finished products daily rinse with sodium nitrite solution

Methods commonly used inter-process rust bearings are the following:
I. dip concentrated solution of sodium nitrite
After washing the product, immersed in a 15% -20% sodium nitrite and 0.6% sodium carbonate solution, and paired tapered bearing then it is stacked up. In this way short of its rust, generally only kept 14 days, but in the rainy season, due to wet weather, keeping only 2-3 days to be reprocessed, it takes labor and money.
Two. Immersed in the tank rust
The bearing trap immersed in 5% aqueous solution of 0.6% sodium nitrite and sodium carbonate, the rust is still good, but a lot of rust tank and other equipment, take up a lot of space management is not easy.
Three. Oiled
Like anti-rust oil painted like a finished product. This method must be cleaned before the next step, more trouble.
New rust process method description:
After the manufacturers double row tapered roller bearing together with related research, years of practice show that for inter-process rust multiple improvements to the use of shower spray type rust better. Roller rust initially conducted the trial, the semi-finished and finished products daily rinse with sodium nitrite solution, three months after testing results found no corrosion, the use of semi-finished products now bearing trap rust shower jet, the effect is also true. Spray rust leaching process is relatively simple, the method is as follows:
A. Process method
