AI Technical Summary
Existing hydraulic motors cannot achieve unidirectional rotation, and the rotation direction changes with the hydraulic flow direction, which cannot meet certain specific rotation needs.
A reciprocating drive unidirectional hydraulic motor is designed. Through the cooperation of alternating reciprocating drive and unidirectional bearings, the motor can only rotate in one direction, and the rotation direction is determined by the installation direction of the unidirectional bearing.
It realizes one-way rotation of the motor, stable rotation direction, small and simple structure, and is suitable for application scenarios where one-way rotation is required.

Abstract
Description
Technical Field
[0001] The present invention belongs to the field of hydraulic motors and is a reciprocating drive single-rotation hydraulic motor. Background Art
[0002] Existing various hydraulic motors can continuously input and rotate continuously. When the hydraulic inlet and outlet flow directions are changed, the rotation direction of the motor also changes accordingly. The motor can rotate forward and backward, and the rotation direction depends on the hydraulic flow direction. Summary of the Invention
[0003] The characteristics of this reciprocating drive single-rotation hydraulic motor are as follows: The motor must be driven reciprocally alternately for continuous rotation and cannot be continuously input. When the inlet and outlet are swapped, the rotation direction of the motor remains unchanged. The motor can only rotate in one direction, and the rotation direction depends on the installation direction of the one-way bearing.
[0004] The reciprocating drive single-rotation hydraulic motor is small in size and simple in structure. There are two inlets and outlets on the motor housing. The inner cavity is divided into two chambers by the spacer layer inside the housing. The oil passage holes on the spacer layer penetrate the two chambers. The stator in the chamber separates the oil passage holes from the inlets and outlets. There is a swing rotor in each chamber. The two rotors are sleeved on a motor shaft through two one-way bearings. When one rotor is forced to swing, it drives the shaft to rotate through the one-way bearing. At the same time, the working rotor pushes the non-working rotor in the other chamber back to its position through the oil passage hole. The two rotors are alternately forced to swing and work, driving the motor shaft to rotate in one direction. Description of the Drawings
