Low-temperature and large-temperature-variation joint bearing test platform

Abstract

The invention provides a low-temperature and large-temperature-variation joint bearing test platform. The low-temperature and large-temperature-variation joint bearing test platform comprises a motionand load simulation system for clamping the joint bearing under the low-temperature, large-temperature-variation, vacuum, and atmosphere environment and realizing the motion loading of the joint bearing; an environment measurement and control system cooperated with the motion and load simulation system and used for measuring and controlling the located environment atmosphere of the joint bearing,thereby enabling the joint bearing to be tested and measured under the low-temperature, large-temperature-variation, vacuum, and atmosphere environment; and a measurement and data collection system cooperated with the motion and load simulation system and the environment measurement and control system and used for realizing the friction of the joint bearing under a special working condition environment. A means is provided for researching and checking the joint bearing performance parameters and influence factors thereof, and designing the joint bearing suitable for the special working condition environment, and the reliability of the joint bearing is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of bearing test equipment, in particular to a low-temperature large-temperature-change joint bearing test platform. Background technique [0002] At present, Shimizu T of NTN Bearing Co., Ltd. of Japan and others have conducted related bearing wear tests using a joint bearing swing wear tester that swings by a motor and a crank rocker structure. The articulated bearing variable load life testing machine used by Lancaster JK of the Royal Aeronautical Research Institute uses hydraulic reciprocating actuators to achieve swing and is loaded by hydraulic pressure. Sliney HE et al., Harold E, etc. used NASA’s thermal induction joint bearing testing machine to study the friction and wear performance of the gasket material. The testing machine uses electromagnetic induction heating to test the bearing The temperature reaches 330℃ and can be tested in a vacuum environment. It can simultaneously apply axial load by hydra...
