AI Technical Summary

Problems solved by technology

[0003] At present, curved joint surfaces widely exist in various mechanical structures, such as spherical joints in mechanisms, bearing rollers, etc. For curved joint surfaces made of different materials, it is necessary to obtain their friction and wear characteristics, and through comparison The friction and wear properties of the joint surfaces of different materials are good or bad, which provides guidance for the material selection of the joint surface joint surfaces in practical applications, but there is no solution to this kind of problem in engineering applications

The traditional curved surface bonding surface generally uses several specific known materials, and the evaluation of its friction and wear characteristics is often based on empirical values. There is no specific test equipment for quantitative testing, resulting in the actual friction and wear of the bonding surface and reliability. The estimated value is inaccurate, resulting in equipment loss; in addition, although some test benches can easily measure the friction performance of curved surfaces, the equipment is too simple, the data is not reliable, and there is no good interchangeability, that is, the same test bench cannot test The friction and wear characteristics of joint surfaces of different materials lead to problems such as high cost of the test bench and low reuse rate
