The platform comprises a measurement and acquisition module, a power module and a loading module; the measurement and acquisition module comprises a sample cavity, a compatible fixture mechanism and a signal acquisition module; the compatible clamp mechanism and the signal acquisition system are installed in the sample cavity, the upper end of the sample cavity is connected withthe power module through a connecting shaft, and the lower end of the sample cavity is connected with the loading module through a loading base. According to the invention, a worm and gear adjustingmechanism is designed, so when different types of thrust ball bearings are tested, a clamp device does not need to be replaced and disassembled, and automatic and accurate positioning of the sensor isrealized; the synchronous high-precision measurement of normal loading and friction torque borne by the thrust ball bearing to be measured can be realized through the six-axis sensor; multi-parameteracquisition is realized, and the defect that the research parameters of the bearing experiment device are single is overcome.

Description

technical field [0001] The invention relates to the technical field of bearing performance tests, in particular to a multi-parameter test platform for high-precision thrust ball bearings that can conveniently disassemble and assemble samples. Background technique [0002] Most of the existing thrust ball bearing test platforms are composed of three parts: clamping and measuring device, power device, and loading device. The clamping device is used to fix the bearing sample, and the power device and loading device are used to provide the speed required for the experiment. and normal pressure to simulate working conditions. [0003] Common bearing test platforms need to install bearing fixtures of corresponding sizes for different types of bearing samples, and indirect measurement methods are often used to measure the friction torque of bearing samples. In addition, the existing bearing test bench studies the performance parameters of the bearing samples relatively single, and...

AI Technical Summary

Problems solved by technology

In addition, the existing bearing test bench studies the performance parameters of bearing samples relatively single, and it is impossible to collect multiple performance parameters of bearing samples at the same time.

[0004] In the test and research of bearing lubrication characteristics, it is often necessary to conduct experiments on bearings of different sizes. In the specific test, when replacing different types of bearings, it is necessary to replace the corresponding size of the fixture, and at the same time, it is necessary to adjust the position of the measurement sensor to ensure the measurement accuracy. It takes a lot of time to install samples and fixtures, and the efficiency is not high when the batch of bearings is large

[0005] In the experimental research on the lubrication characteristics of common thrust ball bearings, indirect measurement of the friction torque of bearing samples is used, which cannot achieve simultaneous and direct and accurate measurement of the normal pressure and friction torque of the experimental bearing, which poses a challenge to the structural design of the thrust ball bearing experimental device
