Low temperature and large temperature variable joint bearing test platform and measurement method for joint bearings

Abstract

The invention provides a low-temperature and large-temperature variable joint bearing test platform and a measurement method for the joint bearing. The low temperature and large temperature variable joint bearing test platform includes: motion and load simulation system; environmental measurement and control system; programmable logic controller; The gap and wear amount measuring device is connected with the motion and load simulation system and the environment measurement and control system, and is electrically connected with the programmable logic controller, and the measurement and data acquisition system transmits the measurement data to the programmable logic controller. A logic controller is programmed and controlled by the programmable logic controller. Realize the wear amount and in-situ clearance measurement of spherical plain bearings under special working conditions, provide means for researching and testing the performance parameters of spherical plain bearings and their influencing factors under special working conditions, and design and optimize spherical plain bearings suitable for special working conditions, ensuring Reliability of spherical plain bearings.

Description

technical field [0001] The invention relates to the technical field of bearing test equipment, in particular to a low-temperature and large-temperature variable joint bearing test platform and a measurement method for the joint bearing. 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 ca...
