Multifunctional tribology performance test system

Abstract

The invention discloses a multifunctional tribology performance test system, which comprises a test cabin body, a bearing sleeve, a test shaft, a shaft sleeve, a test shaft driving device, a loading device and a comprehensive performance test unit. An installation space of a piece to be tested is arranged between the shaft sleeve and the bearing sleeve. Two ends of the test cabin body are respectively in rotation sealing fit with the test shaft, and a lubricant inlet and a lubricant outlet are arranged on the test cabin body. The comprehensive performance test unit comprises a computer, a torque rotating speed detection device, a loading force detection device, a lubricant temperature detection device, a liquid film thickness detection device and a lubricant flow detection device. The multifunctional tribology performance test system can simultaneously conduct radial and axial loading, simulates actual complex working conditions of the piece to be tested truly, achieves tests of tribology comprehensive performance such as rotating speed, torque, temperature rise, friction characteristic, test loading force, production validation (PV) value, dynamic rigidity and dynamic damping, and is capable of really and comprehensively testing and verifying the comprehensive performance of the piece to be tested.

Description

technical field [0001] The invention relates to a test device, in particular to an experimental system for comprehensive performance testing of sliding bearings, ring blocks, especially metal sliding bearings, water-lubricated bearings, and water-lubricated dynamic and sealed bearings. Background technique [0002] Metal sliding bearings, water-lubricated bearings, water-lubricated dynamic seal bearings and other mechanical basic parts are widely used in mechanical transmissions, especially in mechanical devices such as ships, water turbines, steam turbines, and water pumps. Water-lubricated bearings use new engineering composite materials instead of precious metals as the friction pair, and use natural water instead of mineral oil as the lubricating medium. The rubber alloy bushing with multi-curved arc and straight grooves and the metal shell are organically combined, with a small friction coefficient. , wear resistance, vibration reduction, low noise, light weight, easy a...

Problems solved by technology

[0004] However, the comprehensive performance testing methods for metal sliding bearings, water-lubricated bearings, and water-lubricated dynamic-sealed bearings in the current technology are not perfect, and there is no experiment that can truly and completely simulate the actual working conditions of metal sliding bearings, water-lubricated bearings, and water-lubricated dynamic-sealed bearings. The system, especially the excitation loading, does not have advanced testing equipment and testing methods to conduct comprehensive performance tests on metal sliding bearings, water-lubricated bearings, and water-lubricated dynamic and sealed bearings.
