Low temperature and large temperature variable spherical plain 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 testing equipment, in particular to a low-temperature and large-temperature variable joint bearing testing platform. Background technique [0002] At present, Shimizu T of Japan NTN Bearing Co., Ltd. has carried out related bearing wear tests using a joint bearing swing wear tester that is oscillated by a motor and a crank rocker structure. The joint bearing variable load life testing machine used by Lancaster J K of the Royal Aeronautical Research Institute of the United Kingdom uses hydraulic reciprocating actuators to realize swing and load through hydraulic pressure. Sliney H E et al., Harold E et al. used the thermal induction joint bearing testing machine of NASA to study the friction and wear properties of the lining material. The testing machine uses electromagnetic induction heating to make the test bearing The temperature reaches 340°C, and it can be tested in a vacuum environment. It ...
