Dynamic simulation test method and device for bearing lubrication grease in high temperature environment

Abstract

The invention relates to a device for a dynamic simulation test of bearing lubricant grease at a high temperature, which consists of a driving motor 1, a shaft coupling 2, a rear supporting point bearing 3, a main shaft 4, a front supporting point bearing 5, a radial loading spring 6, a loading sleeve 8, an axial loading spring 9, an upper cover 10, an electric heater 11, a temperature controller12, and a lower cover 13. The lubricant grease is filled in a test bearing 7 which is placed in a sealed high-temperature box; the electric heater is arranged in the box and is controlled by the temperature controller, and the maximum heating temperature can reach 200 DEG C; the test bearing filled with the lubricant grease is arranged on a cantilever end of the main shaft, is supported by two supporting point bearings and is connected with the driving motor through the shaft coupling to rotate; the test bearing is provided with the loading sleeve and is applied with force by the radial and the axial loading springs; the loading sleeve transmits the force of the springs to the test bearing which simulates a dynamic stressed condition under a high-temperature state; the test bearing is dismounted when the device runs to a prescribed time; and the lubricant grease is detected and analyzed. The whole test process is under automatic measurement and control.

Description

technical field [0001] The invention belongs to the technical field of bearing lubricating grease tests, and in particular relates to a method and device for a dynamic simulation test of bearing lubricating grease in a high-temperature environment. Background technique [0002] At present, the method of high-temperature performance test for bearing lubricating grease belongs to the static measurement method. The tested grease is directly placed in a high-temperature oven. The temperature of the oven can be controlled. By observing and analyzing the performance of the grease at different temperatures, the high-temperature performance of the grease is tested. assessment. [0003] This measurement method does not consider the actual working conditions of the lubricating grease in the bearing, and cannot simulate the use effect of the lubricating grease in the normal operation of the bearing, thus affecting the correct evaluation of its high temperature performance.
