Abstract

The invention discloses a ball piston type radial rolling hydraulic motor with multi-row radial balls. The ball piston type radial rolling hydraulic motor comprises an oil distribution assembly, a cylindrical rotor and a stator. The ball piston type radial rolling hydraulic motor has the advantages that rotating torque on the rotor can be generated under the effect of high-pressure hydraulic oil, corresponding rotating power can be outputted according to the inputted flux of the hydraulic oil and the pressure, the ball piston type radial rolling hydraulic motor is smart in design, low in friction force and energy consumption and high in energy conversion efficiency, and can run stably and reliably, and a good lubricating effect can be realized among movable components.

Description

technical field [0001] The present invention relates to improved technology of hydraulic motors. Background technique [0002] Existing high-pressure and large-flow hydraulic motors, radial hydraulic motors are large in size, and the holding force, torque and friction generated by the plunger and cylinder of the inclined-axis swash plate plunger motor are large, resulting in mechanical energy loss and loss The rate is relatively large. Contents of the invention [0003] In view of this, the present invention provides a radial multi-arrangement centripetal ball rolling hydraulic motor capable of outputting corresponding rotation speed and torque according to the input hydraulic oil flow rate and pressure. [0004] The design scheme that the present invention takes is: [0005] A radial multi-arrangement radial ball rolling hydraulic motor comprising: [0006] An oil distribution part, the oil distribution part includes a disc-shaped outer end with a large outer dia...
