Abstract

The invention discloses a bearing impact friction-wear testing machine. The bearing impact friction-wear testing machine comprises a test stand, a main drive system, a friction pair system, a radial impact system, a hydraulic loading system, a temperature and humidity control system, a signal acquisition and detection system and a computer. The working condition in the friction pair system duringa bearing friction-wear test is changed through the main drive system, the hydraulic loading system and the temperature and humidity control system, and the vibration condition in the vibration bearing operation is simulated by the radial impact system; and the bearing friction-wear output parameters in the friction pair system are collected and monitored in real time by the signal acquisition anddetection system, and are transmitted to the computer through a data acquisition card for data processing and analysis so as to carry out a friction-wear test of a bearing under the coupling effect of impact and friction. The bearing impact friction-wear testing machine provides an effective testing platform for studying the wear behavior of the bearing under the coupling effect of the impact andfriction, and the collected test parameters can be used as judging criterions for bearing wear state identification.

Description

technical field [0001] The invention relates to a bearing impact friction and wear testing machine, which can conduct friction and wear tests of bearings under different working conditions and research on wear behavior of bearings under impact and friction coupling, and belongs to the technical field of material friction and wear performance research. Background technique [0002] Vibration machinery is an important engineering construction and industrial production equipment, and it occupies a large proportion in mechanical equipment. Vibrating machinery relies on high-frequency and high-intensity vibration to achieve work, which has a great impact on the life and reliability of bearings. Bearings are indispensable basic parts in modern industrial applications, and rolling bearings are vividly called "industrial joints". Whether the bearings are in normal operation usually directly affects the performance of the entire equipment (accuracy, reliability and life, etc.) ). W...
