The space rolling bearing comprehensive performance experiment device can simultaneously conduct axial force and radial force accurate load on a measured bearing through an axial loading device and a radial loading device. A three-axis acceleration sensor is used for measuring radial, axial and peripheral vibration situations of the measured bearing. A temperature sensor is used for measuring the temperature rise situation of the measured bearing. A pressure sensor is used for measuring the friction moment of the measured bearing. An annular pressure sensor is used for measuring axial force borne by the measured bearing. Weights are used for marking radial force borne by the measured bearing. The space rolling bearing comprehensive performance experiment device can evaluate the comprehensive performance of the space rolling bearing and provide key scientific technical basis and test platform support for development of high-end bearings in the aerospace field of our country.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device for comprehensive performance detection of rolling bearings under space environment conditions. Background technique [0002] Bearings are key components necessary for supporting and maintaining the aerospace industry, and are closely related to the development and technological progress of the aerospace industry. The technical level, performance and quality of bearings directly affect the performance life and reliability of aircraft, rockets, satellites and other aerospace vehicles. Compared with civilian bearings, space rolling bearings have very strict requirements in terms of precision, speed, sensitivity, life, reliability, temperature, vacuum, corrosion, radiation, etc. In order to meet these requirements, corresponding technical measures must be taken in all aspects of bearing design, material selection, processing, testing, testing, lubrication, use, and m...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the comprehensive performance testing methods for rolling bearings are not perfect, and there is no experimental device that can truly and completely simulate the actual working conditions of space rolling bearings, especially the axial and radial loading are not considered at the same time, especially the impact of rotational speed and load on the bearing cannot be accurately measured. The relationship between the friction torque, temperature rise and vibration of space rolling bearings, so that the failure mechanism and tribological properties of space rolling bearings cannot be truly grasped
