Abstract

A continuous rotary motor blade and stator friction pair with surface textures relates to the field of hydraulic transmission, and is mainly characterized in that a plurality of pit texture unit bodies are arranged on the inner surface of a stator and the top friction surface of a blade of the friction pair to form a non-smooth surface form; the friction surfaces, with the surface textures, of the friction pair are the friction surface of the inner surface of the stator and the friction surface of the top of the blade. According to the invention, the friction characteristic of the continuous rotary motor blade and the stator friction pair can be reasonably improved with high cost performance, and the ultra-low speed performance of the motor is improved.

Description

technical field [0001] The invention relates to the field of hydraulic transmission, in particular to a continuous rotary motor blade and stator friction pair with surface texture, which is used for reducing the influence of friction on the low-speed performance of the continuous rotary motor and prolonging the service life of the motor. Background technique [0002] The simulation turntable can realistically simulate the various attitudes of the aircraft during actual flight in space, and reproduce its dynamic characteristics during operation, so as to test the performance of the aircraft's sensor devices, guidance systems, control systems and various actuators. Or the redesign and improvement of the aircraft provide sufficient technical indicators and experimental data to meet the performance requirements of the overall design of the aircraft. The large-load simulation turntable at home and abroad generally adopts the hydraulic direct drive method, that is, each frame of t...
