Crossed roller bearings quality judgment on several factors

In the cross roller bearing grinding, the grinding wheel and the workpiece contact area, a small amount of energy consumption, the occurrence of a small amount of grinding heat, forming part of Shashi cryogenic grinding zone. Practical application of linear stationary heat transfer formula derivation, contemplating or applying red paint method and thermocouple method under test conditions Shashi measured temperature can be invented within the 0.1 ~ 0.001ms Shashi grinding zone temperature can be as high as 1000 to 1500 ℃. This instant cold enough to make the task certainly looks the outer surface of the depth of occurrence of low-temperature oxidation, amorphous tissue, tempering, secondary hardening, cracking or burn a variety of changes.
1, through the surface bearing quality feeling
Crossed roller bearings in the process a lot of customers that as long as the bearing surface brightness is of good quality, which is wrong. Bearing surfaces should be kind of bright glossy black, glossy black reasons causing this bearing steels are used in compliance with its grinding and cutting fluid used, such as arising, in which the former two based.
2, chamfer is bright
Bearing chamfer does not determine the quality of the bearing, but reflects the processing method of the bearing. Chamfer is black, shows that, after hardening heat treatment, thus increasing the hardness of cross roller bearings, and some people think that the chamfer is black does not look good is not processed completely, this is a misunderstanding.
3, one of the cage than two body good, although the use of new technology are integrated cage, but it is only saves material, while rotating, worse performance than the two bodies.
Overall, cross roller bearing life has a relationship with the three factors, namely the quality of the bearing itself. Second, the use of the environment. Third, the installation method.
