Low-temperature large-temperature variable joint bearing test platform and joint bearing measurement method

Abstract

The invention provides a low-temperature large-temperature variable joint bearing test platform and a joint bearing measurement method. The low-temperature large-temperature variable joint bearing test platform comprises a motion and load simulation system; an environment measurement and control system; a programmable logic controller; a host computer; and a measurement and data acquisition system; the measurement and data acquisition system comprises a clearance and wear measuring device; the clearance and wear measuring device is connected with the motion and load simulation system and the environment measurement and control system, and electrically connected with the programmable logic controller; and the measurement and data acquisition system transmits measurement data to the programmable logic controller and is controlled by the programmable logic controller. According to the low-temperature large-temperature variable joint bearing test platform provided by the invention, the wear and in-situ clearance measurement of a joint bearing in a special working condition environment are achieved, a means is provided for researching and inspecting performance parameters and influencing factors of the joint bearing in special working conditions, and designing and optimizing the joint bearing suitable for special working condition environment, thereby ensuring the reliability of thejoint bearing.

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...
