Problems solved by technology

The rear spacer of the high-speed distribution cycloidal hydraulic motor in the prior art cannot make the motor have a better axial clearance compensation function under high pressure. It is widely used in wheel flanges, and needs to have a large radial support capacity to support the weight of the whole machine, such as B-3016 and other types of needle roller bearings. However, due to its structural limitations, the ability of the motor to withstand large radial forces cannot be obtained. It is very good to improve, but it cannot meet the user's requirements under many heavy load conditions

Abstract

The invention relates to a short-shell axially compact high-speed flow distribution cycloid hydraulic motor, and belongs to the technical field of hydraulic transmission. The cycloid hydraulic motor comprises a shell and a flow distribution mechanism, wherein the shell is provided with a liquid inlet and a reflux inlet; a rotor of a cycloid-pin wheel set and a composite hydraulic passageway of a flow distribution support plate form the flow distribution mechanism; the rotor contacts a compensation plate; the two planes of the compensation plate form slightly concave surface structures or convex surface structures; a front bearing of an output shaft is supported by a full complement roller bearing; the axial length of the shell is short. The axial size of the motor is compact, high pressure can be born by the motor, and the motor can bear strong radial force.

Description

technical field [0001] The invention relates to a cycloidal hydraulic motor which converts hydraulic energy to mechanical energy through the meshing pair of cycloidal pinwheel group, in particular to a cycloidal hydraulic motor with a very short casing and an axially compact high-speed flow distribution cycloidal hydraulic motor, which belongs to the hydraulic motor field of transmission technology. Background technique [0002] The cycloidal hydraulic motor is not only a commonly used hydraulic drive device, but also a commonly used hydraulic actuator to realize the conversion of hydraulic energy into mechanical energy. The cycloidal hydraulic motor has the advantages of small size, high unit power density, high efficiency, and wide speed range, so it has been widely used. [0003] The basic structure of this type of device is that the body shell or the back cover is formed with a liquid inlet and a return port, and one end is equipped with a cycloidal pinwheel meshing pai...
