Description

technical field

[0001] The invention relates to the technical field of bearing tests, in particular to a test method for simultaneous rotation of inner and outer rings of cylindrical roller bearings. Background technique

[0002] Bearings are widely used core mechanical basic parts, widely used in various fields of national economy and national defense, and bearings are called "industrial joints" in the national economy. As a standardized and highly specialized product, bearings have complex working conditions. Sometimes even if the shape is the same or even the precision is high, it may not meet the actual requirements. Some special testing and testing equipment must be used to simulate the work. To test whether it meets the required technical requirements. Therefore, in the research and development process of bearings, the test of bearings is a very important link.

[0003] The bearing test methods in the prior art can be roughly divided into three categories. One is th...

Embodiment Construction

[0027] Embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0028] Such as figure 1 As shown, a test method for the simultaneous rotation of the inner and outer rings of a cylindrical roller bearing. The test device used for this test method includes a base, and also includes an inner ring rotation system and a driving system arranged above the base to drive the inner ring of the test bearing 7 to rotate. The outer ring slewing system of the test bearing 7 whose outer ring rotates, the center line of the inner ring slewing system and the rotation center line of the outer ring slewing system are located on the same straight line; the outer ring slewing system includes the outer ring main shaft 9, the outer ring main shaft One end of 9 is axially fixed, and the other end is fixedly connected with the outer ring of the test bearing 7, and an accompanying test bearing 8 is set in the middle of the outer ring main ...
