Abstract

The invention provides a comprehensive performance test table for a water-lubricated dynamic-static pressure radial sliding bearing, comprising a box and main shaft. The main shaft penetrates through the box; a radial sliding bearing is sleeved on the part of the main shaft, which is in the box; the radial sliding bearing is fixed in a radial sliding bearing pedestal; the radial sliding bearing pedestal is arranged in a loading cylinder which is fixed at the bottom of the box; a static-pressure water cavity is formed in the gap between the radial sliding bearing pedestal and the loading cylinder, and the static-pressure water cavity is communicated with a loading connection pipe; the gap between the main shaft and the radial sliding bearing is communicated with a water inlet pipe; the side wall of the box is provided with a drain pipe; a displacement sensor which is used for measuring the horizontal displacement and the vertical displacement of the main shaft is arranged near the main shaft; a pressure sensor and a temperature sensor are arranged on the matching surface of the main shaft and the radial sliding bearing; and a rotation torque and speed sensor is arranged on the input end of the main shaft. The comprehensive performance test table adopts the pure water lubrication and can simulate various working conditions and test the pressure, the temperature, the thickness, the friction coefficient, the axial displacement, the deviation angle and other parameters of the water film to provide valuable basis for the design of the radial sliding bearing which is used for the water hydraulic pump, the motor and related water-lubricated machinery.

Description

technical field

[0001] The invention relates to the field of bearing performance testing, in particular to a comprehensive performance testing test bench for radial sliding bearings. Background technique

[0002] Pure water hydraulic transmission is one of the frontier directions in the field of modern hydraulic research. Due to the advantages of wide sources of pure water, good flame retardancy, low price and no pollution, pure water hydraulic transmission technology has a very wide application prospect in industrial production and other fields. The pure water hydraulic pump and hydraulic motor are the core components of the pure water hydraulic system, and their performance directly affects the reliability of the entire pure water hydraulic system. Radial sliding bearings are key components of such components, and their structural form and basic parameters directly affect the performance, reliability and service life of water hydraulic pumps or motors. The advantages of ...
