In the selection of angular contact bearings, there are often some technical problems, many of which are not common in our daily bearing selection process, such as the inner ring lock and outer ring lock of angular contact ball bearings, and even many people who are engaged in bearing sales, Will not understand, of course, if the bearing is selected according to the standard code, such a problem does not exist, but if you need to design the shaft and bearing chamber, you need to have a deep understanding of the bearing structure. We must first have a preliminary understanding of the definition of locks. The design process of angular contact ball bearings must take locks into account. It is a necessary process for the production of angular contact ball bearings, that is, angular contact ball bearings must have suitable assembly locks. . If the lock is too large, the steel ball will be scratched during assembly; if the assembly lock is too small, the bearing will be scattered after assembly, that is, the inner ring and the ring will be easily separated, causing the steel ball to fall off. We understand what the lock is, and choose a bearing. It's easy. According to your angular contact ball bearing installation environment and specific conditions, select the allowable lock position when installing the angular contact ball bearing, so that the problem can be solved. The torque is accurate, in order to turn stable!
