Description

technical field

[0001] The invention belongs to the technical field of testing the frictional energy consumption characteristics of rolling bearings, and relates to a device and method for measuring equivalent friction coefficients of horizontal rolling bearings. Background technique

[0002] The friction energy consumption during the operation of rolling bearings directly affects the heating, temperature rise and wear of bearings, which in turn affects the performance and life of rolling bearings. The friction energy consumption characteristic of rolling bearing is an inherent characteristic of rolling bearing itself, which reflects the manufacturing quality and cleanliness of rolling bearing to a certain extent.

[0003] At this stage, starting friction torque and rolling friction torque are used to evaluate the starting friction energy consumption and rolling friction energy consumption of rolling bearings respectively, and various rolling bearing friction torque measurin...
