A convenient replacement friction pair thrust bearing experimental device

Abstract

The invention discloses a thrust bearing experimental device capable of replacing a friction pair conveniently. The thrust bearing experimental device comprises an experimental cavity constituted by an experimental cavity base, an experimental cavity, and an experimental cavity top cover. The experimental cavity is filled with lubrication medium, and a testing bearing constituted by a bearing pedestal, an experimental thrust bearing shoe, and a friction pair disc is disposed in the experimental cavity. The bearing pedestal is disposed on the experimental cavity base, and the friction pair disc is provided with a thrust disc, and is fixedly connected with the thrust disc by a torque transmission pin. A rotating shaft passes through the experimental cavity, and is fixedly connected with the thrust disc. The thrust bearing experimental device is advantageous in that the problem that the replacement of the pairing friction pair requiring the replacement of the whole thrust disc is prevented, and the replacement cost is reduced, and at the same time, the experimental devices has a wider material application range; the radial and axial limiting of the experimental thrust bearing shoe is realized, and the assembly process is simplified; after the simple disassembly process, the experimental thrust bearing shoe can be taken out along a radial direction without disassembling the shafting, and therefore the centring performance of the whole shafting cannot be affected, and the requirement of the material pairing experiment on the frequent replacement of the experimental thrust bearing shoe is satisfied.

Description

technical field [0001] The invention belongs to the technical field of bearing performance experiments, and in particular relates to an experimental device for thrust bearings that can conveniently replace friction pairs. Background technique [0002] Thrust bearings are the foundation and key components of mechanical systems, and their performance directly determines the life and reliability of the entire mechanical system. Especially for large thrust bearings, the high linear velocity at large sizes will bring about problems such as high Reynolds number and turbulent flow, which are different from those at small sizes. Accurately testing the performance and reliability of thrust bearings at this time becomes the focus of bearing testing. The essential. Under different lubricating medium conditions, thrust bearings have many possible friction pairs, and it is necessary to obtain the best bearing material pairing between different materials through optimization. Under diff...
