Abstract

The invention provides a testing machine for testing tribological performance after a bearing bears overloading impact, which can test the tribological performances after the bearing bears the overloading impact at different impact inertias, different rotating speeds, different ambient temperatures and different lubricating mediums. The testing machine comprises a driving device, a loading device, a detecting device, an experimental cavity device and a control device, wherein the driving device comprises a variable-frequency and speed-regulating motor, a big belt wheel, a small belt wheel and a driving shaft; the loading device comprises a hydraulic system, a weight and a lever device; the detecting device comprises an acceleration sensor, a temperature sensor, a speed sensor, a pull-pressure sensor, a numerical simulation converter and an industrial control computer; and the experimental cavity device comprises an experimental cavity, a cylindrical buckled-type high-temperature furnace, a bearing sample, a cushion block and a sampling bearing. The testing machine simulates different working conditions by regulating the rotating speed of the variable-frequency and speed-regulating motor and the temperature of the cylindrical buckled-type high-temperature furnace, carries out the overloading impact to the bearing by the loading device and tests the tribological comprehensive performance of the bearing by the testing device.

Description

technical field [0001] The invention relates to an experimental machine for testing the tribological performance of bearings subjected to overload impacts, which can detect the tribological properties of bearings after overload impacts under different impact inertias, different rotational speeds, different ambient temperatures, and different lubricating media. Background technique [0002] The bearing relies on the mutual contact between the raceway and the rolling elements (steel balls, rollers) to support the load. The test machine for bearings such as "Bearing Ball Rolling Contact Fatigue Life Test Machine" (Chinese Patent 03230586.9) discloses a special test machine for bearings. Experimental machine for sphere contact fatigue. "The rotational speed of the automobile hub bearing test machine, the torque transmission mechanism" (Chinese patent 200820148908.7) discloses a kind of experimental machine specially used for the automobile hub bearing. Under special working con...
