Description

Technical Field

[0001] This utility model relates to the field of bearing cage strength testing technology, specifically a bearing cage strength testing device. Background Technology

[0002] The cage is one of the important components of a bearing. Its basic function is to isolate the rolling elements at equal intervals and prevent them from falling out, and to guide and drive the rolling elements to rotate. When a rolling bearing is working, the cage will be subjected to various mechanical stresses such as friction and centrifugal force. Therefore, it is necessary to test the strength of the bearing cage during its production to ensure that it can function properly. However, some current testing devices require manual loading and unloading after testing. When testing a large number of bearing cages, the workload of the workers will increase, and high-intensity work will lead to a decrease in work efficiency. To address these issues, a bearing cage strength testing device is needed. Utility Model Content
