The invention discloses a water lubricated bearing and
transmission system comprehensive performance testing platform, which comprises a water lubricated bearing, a dynamic seal device, an elastic
coupling, a gearbox, a water circulating
system, a driving motor, an intermediate bearing, a bearing block, a loading and testing device and other parts. The loading device loads a test shaft in the circumferential direction, axial direction and radial direction so as to simulate complicated working conditions of the water lubricated bearing and the
transmission system thereof; the testing
system can detect various parameters of the water lubricated bearing, such as working speed, torque, temperature, frictional characteristics, water
film pressure distribution, interface deformation distribution, shaft centerline
orbit,
noise and dynamic characteristics, and comprehensive performance of the dynamic seal, the elastic
coupling and the
transmission system on line; and the testing platform can be applied to research of scientific problems such as the loading bearing of a water lubricated friction pair,
failure mechanism and evolution law, tribological performance and dynamic service behaviors, and provides a key scientific and technological basis for developing a
pollution-free, low-
noise, high-reliability, long-life, high-efficiency and energy-saving water lubricated bearing and a transmission
system thereof.
