Abstract

The invention discloses an inverted tilting-pad sliding bearing test bed. The test bed comprises a rack; a main shaft which is used for mounting a tilting-pad sliding bearing and is rotationally supported on the rack; a loading seat which is fixed on a shell of the tilting pad sliding bearing; a flexible connecting piece one end of which is connected to the rack in a hanging manner, and the other end is fixedly connected with the loading seat; a loader of which the output end acts on the loading seat; and a vibration exciter of which the output end acts on the loading seat. By means of the test bed, the dynamic characteristic and static characteristic tests and performance research of the sliding bearing are completed by simulating the normal work of the tilting-pad bearing, and help is provided for the further optimization of the bearing structure.

Description

technical field [0001] The present application relates to the technical field of bearing loading tests, in particular to an inverted tilting pad sliding bearing test bench. Background technique [0002] In many large rotating mechanical equipment, such as water turbines, steam turbines, nuclear power plants, etc., ordinary sliding bearings can no longer meet the requirements of high load-carrying performance and low power consumption, while tilting pad sliding bearings have a multi-watt structure and can self-align , so compared with traditional bearings, it has higher load capacity and more stable performance. [0003] At present, most of the dynamic performance and static performance tests of tilting pad sliding bearings are based on theoretical calculations and CFD simulation calculations, and no actual tests have been carried out. Contents of the invention [0004] In view of this, an embodiment of the present application provides an inverted tilting pad sliding beari...
