Abstract

The invention relates to an apparatus used for a bearing wearing test. The apparatus includes a double-fork pedestal (1), a bearing test piece (2) is installed on the double-fork pedestal (1) through a mandrel (3), the upper portion of the bearing test piece (2) is attached to a loading single ear (4), the loading single ear (4) is connected with a loading actuating cylinder (6), the loading actuating cylinder (6) downward applies radial vertical compression to the bearing test piece (2), and the above assemblies are disposed in a temperature test box (8); and the mandrel (3) is connected with a swing actuating cylinder (10), the swing actuating cylinder (10) drives the mandrel (3) to rotationally move back and forth at +/-25DEG, and the mandrel (3) is provided with a torque sensor (9) and a spacing sensor (11). Compared with apparatuses in the prior art, the apparatus provided by the invention has the advantages of realization of the various requirements of performance tests of a bearing and a liner which are used by an undercarriage, satisfying of the various requirements of the performances of joint bearing test pieces in Technological Standard of Aerospace Series of Corrosion Resistant Steel Made Self-lubricating Loading Joint Bearing, test cost reduction, and energy consumption saving.

Description

technical field [0001] The invention relates to a device for bearing wear test, which belongs to the technical field of product structure. Background technique [0002] At present, lightweight AIRFLON and other materials are widely used as liners for joint bearings in aircraft landing gear systems, or lighter AIRFLON bushes are directly used. However, due to the obstruction of imported liner materials, joint bearings and bushes are often out of stock. Since the liner material is an important functional material for bearings and bushings, a series of wear performance tests are required for spherical plain bearings and bushings produced with domestic liner materials. [0003] At present, only Hafei Design Laboratory and Shanghai Bearing Research Institute can conduct bearing wear tests in China. However, the difficulty in realizing the low temperature state test, the real-time monitoring of the wear of the test piece, and the safety control and protection of the test piece ar...
