Lubricating grease aging simulation test device under thermal field-force field coupling effect and application thereof

Abstract

The invention discloses a lubricating grease aging simulation test device under a thermal field-force field coupling effect and application thereof, the device comprises a driving motor box, a driving shaft, a lifting platform and a simulation bearing mechanical shearing part, a grease filling cylinder is arranged in the simulation bearing mechanical shearing part, and a retainer, a steel ball rolling body and a loading piston are arranged in the grease filling cylinder; the torque sensor is connected with the simulated bearing mechanical shearing part to measure real-time torque and characterize the aging state of the lubricating material after mechanical shearing. The problems that in the prior art, a testing method and testing conditions are single, pertinence is poor, the grease filling assembly process is tedious, and lubricating grease participating in friction on the bearing is difficult to extract after a test is completed are solved. The device is used for simulating the working form of the bearing operation process, a temperature control system of a mechanical shearing part of the bearing is formed, the working condition environment during actual service of the bearing is simulated, and the continuous evolution process of lubricating grease in the dynamic coupling state of a force field and a temperature field is reflected through torque data changes.
