Abstract

The invention relates to a large-shaft-diameter sliding bearing set tribology performance test stand with an adjustable space under movable loads, and belongs to sliding bearing tribology performancetest stands. A test stand lifting supporting device is fixed on a test stand base, a hybrid bearing assisting device is fixed on a test stand lifting support, a hydraulic loading device is fixed on the hybrid bearing assisting device, and a power output system is fixed on a boss of the test stand base. The large-shaft-diameter sliding bearing set tribology performance test stand has the advantagesthat measurement of the sliding bearing tribology performance is achieved, and the defect that most traditional sliding bearing tribology performance test stands cannot make sufficient correspondingsimulation tests according to different bearing parameters and loading conditions. It can be effectively guaranteed that the friction mechanism, the abrasion form, working performance and the like generated by a sliding bearing test piece in the test process are consistent with those during actual use, thus various performance parameters of a sliding bearing can be accurately measured, and guidingtest data is provided for engineering application.

Description

technical field [0001] The invention relates to a sliding bearing tribological performance test bench, which is used for researching and testing the tribological performance of sliding bearings with an inner diameter greater than 200mm and a rotating speed greater than 3000r / min under the conditions of different specifications and different bearing distances. Background technique [0002] Sliding bearings and rolling bearings have the same function but different application occasions. Both bearings have the function of supporting, but sliding bearings are not suitable for some working conditions. A considerable part, and the requirements for the use environment are relatively harsh, so the application of rolling bearings is more common. However, in some special cases, such as the case of very large axial load, there are requirements for the application of sliding bearings, so the study of the tribological properties of sliding bearings is a prerequisite for better applicatio...
