Abstract

The invention relates to a plane distributing cycloidal hydraulic motor for strengthening bearing capacity, belonging to the technical field of a hydraulic transmission. Both ends of an universal driving shaft of the plane distributing cycloidal hydraulic motor for strengthening the bearing capacity are provided with external splines; the external spline at one end of the universal driving shaft is meshed with an internal spline at the inner end of the output shaft, and the external spline at the other end of the universal driving shaft is meshed with the internal spline at the inner end of a rotor of a cycloidal-pin pair; the rotor of the cycloidal-pin pair is further meshed with an external gear at one end of the distribution universal driving shaft through the internal spline, the external spline at the other end of the distribution universal driving shaft is meshed with the internal spline of a flow distribution disk in a flow distribution mechanism; a stopping block is arranged between the universal driving shaft and the distribution universal driving shaft; so that the length of the universal driving shaft of a transmission torque with a large capacity of motor is reduced; the stress of the cycloidal-pin pair is uniformly distributed and moved, and the damage of the cycloidal-pin pair caused by stress is avoided.

Description

technical field

[0001] The invention relates to a cycloidal hydraulic motor which converts hydraulic energy into mechanical energy, in particular to a cycloidal hydraulic motor with a plane flow distribution with enhanced bearing capacity, which belongs to the technical field of hydraulic transmission. 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 pair and a flow distribution mechanism. The flow distribution mechanism can be placed before or after t...
