Problems solved by technology

[0003] However, the comprehensive performance testing methods for water-lubricated bearings and transmission systems in the current technology are not perfect, and there is no detection system that can truly and completely simulate the actual working conditions of water-lubricated bearings and transmission systems, especially for excitation loading, and there is no advanced testing equipment The performance test of water-lubricated bearings and transmission systems is carried out with the test method, especially the water film pressure cannot be accurately measured, so that the load-bearing mechanism, lubrication mechanism and wear mechanism of water-lubricated bearings cannot be truly grasped.
