TIMKEN bearing materials commonly used temperature processing

1, the rolling bearing structure: rolling bearing is generally composed of inner ring and outer ring, rolling body, and a cage. Inner ring is installed in the shaft neck ( In the thrust bearing is called shaft circle) With relatively tight; Outer ring is installed in the base or parts of bearing hole, usually with a loose. Inner and outer ring raceway, when inside and outside the circle relative rotation, rolling body will follow the groove rolling. Is the realization of rolling friction roller rolling element, in addition to the 'rotation', also around the axis of revolution. Shape is spherical, cylindrical, cone column, needle, drum, etc. The role of the cage is separates rolling body evenly. In order to adapt to certain requirements, some TIMKEN bearing can without inner ring or outer ring, or dust, sealing ring structure, etc. 2, commonly used materials: rolling body with the inner and outer circle material requirements of the high hardness and contact fatigue strength, good abrasion resistance and impact toughness. Chromium alloy steel is commonly used in manufacturing, commonly used materials have GCr15, GCr15SiMn, GCr6, GCr9, etc. , after heat treatment the hardness of HRC61 - 65. Maintains a low carbon steel plate stamping and become, is commonly used in high-speed bearing use non-ferrous metals (more Such as brass) Or plastic cage. When the bearing temperature, first of all determine whether false action, such as really rise, should do the following: 1, the bearing installation position is not correct, will cause a larger ball end face and TIMKEN bearing inner race and the outer race against Taiwan axial force, bearing caused by overheating. 2, the use of bearing had better choose the accuracy grade of TIMKEN bearings. 3, the use of bending bearing spindle or different heart fever caused by body hole repair solution is 4, bearing spindle belt too tight to cause fever solution is make the elastic of the belt can be adjusted properly. 5, fever caused by poor lubrication of the solution is to use the provisions, brand of lubricating materials and proper cleaning. 6, assembly quality low fever caused by the solution is to improve the quality of assembly. 7, in the rolling bearing shell run laps cause fever solution is to replace the TIMKEN bearing and wear parts related correcting impeller balance hole diameter and checking static balance value 8, axial force is too large to cause fever solution is cleaning, adjusting seal mouth ring clearance requirement 9, rolling bearing damage caused by bearing heating solution is replaced. When we are in the use of TIMKEN bearings, if it is found that the temperature is very high, is to stop the equipment running, and find out its reason, and provide solution for processing according to the above, but may be due to the reason of bearing heating is different, so the solution is also different, so still have to treat, particular case is particular completed with the help of the technical staff. Rolling bearing is widely used in mechanical support. Its function is under the condition of ensure the bearing have enough life, to supporting shaft and shaft parts, and makes relative rotation, swing and base such as sports, make rotation as far as possible to reduce the friction between, in order to obtain higher transmission efficiency. Commonly used rolling bearing has formulated the national standard, it was designed by using the theory of rolling friction and batch production of standard parts by professional chemical plant. Just according to the working conditions in mechanical design using rolling bearing type and model for composite structure design.
