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

The invention relates to a short-housing axially compact high-speed distribution cycloidal hydraulic motor, which belongs to the technical field of hydraulic transmission. The cycloidal hydraulic motor of the present invention includes a housing with a liquid inlet and a return port, a flow distribution mechanism formed by the rotor of the cycloidal pin wheel pair and the composite hydraulic channel of the distribution support plate, the rotor is in contact with the compensation plate, and the two sides of the compensation plate are in contact with each other. The flatness of each surface presents a slight concave structure or convex structure, the front bearing of the output shaft is supported by a full complement roller bearing, the axial length of the housing is very compact, the motor of the present invention is compact in axial size and can withstand higher The pressure can make the motor withstand large 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...
