Low temperature and large temperature variable joint bearing test platform and motion and load simulation system

Abstract

The invention provides a low-temperature great-temperature-change joint bearing test platform and a movement and load simulation system. The movement and load simulation system comprises an installingsupport seat, a cantilever main shaft mechanism, a bearing clamping and installing component, a load applying mechanism and an outer ring swinging mechanism, wherein the cantilever main shaft mechanism is arranged on the installing support seat; one end of the cantilever main shaft mechanism is provided with an inner ring of a joint bearing; the bearing clamping and installing component is used for clamping and installing an outer ring of the joint bearing and is connected with the outer ring swinging mechanism; the load exerting mechanism is arranged on the installing support seat, is abutted against the bearing clamping and installing component during loading, and is used for exerting the load of the joint bearing; and the outer ring swinging mechanism is arranged on the installing support seat and the bearing exerting mechanism, and is used for deflecting or swinging the outer ring of the joint bearing. The movement and loading of the joint bearing in low-temperature great-temperature-change vacuum and atmosphere environment can be realized; and the test reliability of the joint bearing in an extreme work condition environment is ensured.

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 motion and load simulation system. Background technique [0002] At present, Shimizu T of Japan NTN Bearing Co., Ltd. has carried out related bearing wear experiments 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...
