Abstract

The invention discloses a device for testing friction moment of pairing rolling bearings. The device for testing the friction moment of the pairing rolling bearings comprises a motor, a coupler, the pairing rolling bearings, a stress strain sensor, a strain collection analysis system and a motor controller connected with the motor, wherein the motor, the coupler and the pairing rolling bearings are sequentially installed in a matched mode, and the stress strain sensor and the strain collection analysis system are sequentially connected with the pairing rolling bearings. The device for testing the friction moment of the pairing rolling bearings can overcome the defects that a device for testing the friction moment in the prior art is not suitable for the pairing rolling bearings and is single in a loading mode, poor in practical applicability and the like, and has the advantages of being suitable for the pairing rolling bearings and being good in stability, high in measurement accuracy and good in practical applicability.

Description

technical field [0001] The invention relates to the technical field of rolling bearing friction torque testing, in particular to a friction torque testing device for a pair of rolling bearings. Background technique [0002] In the field of rolling bearing friction torque testing technology, the friction torque of rolling bearings is the result of various factors of the bearing itself, and is the main factor affecting the smooth operation and service life of the bearing. Excessive friction torque of rolling bearings will cause the temperature of the bearing to rise; excessive temperature If it rises, the lubricant will deteriorate, the wear will increase, and even the rolling surface will be burned, and the bearing will be damaged. Friction torque is the main factor that must be considered in bearing design and bearing application, so the accurate measurement of friction torque of rolling bearings has good guiding significance for bearing design and application. [0003] The...
