[0004] As far as the applicant knows, the flow distribution mechanism of the existing shaft distribution cycloidal hydraulic motor communicates with the rotor stator pair through a partition plate, and the oil hole of the partition plate is connected with the oil through hole of the flow distribution mechanism, which is a concentric hole or a concentric semicircle. The waist-shaped hole communicates with the connecting bolt hole. Due to the position limitation of the oil through hole of the distribution mechanism, the gap between it and the distribution hole of the distribution mechanism is small, resulting in the oil hole of the partition plate and the distribution hole of the distribution mechanism Small gaps are not conducive to preventing oil leakage and hydraulic damping due to the restriction of the oil hole of the spacer

Embodiment 1

[0021] The basic structure of the shaft distribution cycloid hydraulic motor of this embodiment is as follows: figure 2 As shown, it mainly includes the output shaft 1, the front cover 5, the body shell 9, the linkage shaft 21, the spacer 12, the rotating stator pin wheel pair 13, 14 and 20, the rear cover 15, etc., wherein the cycloid pin wheel meshing pair is composed of the rotor , stator and needle teeth or rotor and integral stator, the stator 14, the partition plate 12 and the rear cover 15 are fixed together on the body shell 9 by bolts 19, thus forming seven distribution channels only in the same body shell 9, A cavity in which the high and low pressure oil passage holes of the partition plate 12 are communicated one by one.

[0022] The structural schematic diagram of the spacer 12 is image 3 As shown, there are two annular distribution channels with different distribution circles on the circular surface, the outer ring channel is a bolt connection channel, and the...

Abstract

The invention relates to a cycloid hydraulic motor oil hole, and belongs to the technical field of hydraulic transmission. Compound oil holes of an oil liquid passage formed by four segments of circular arcs are formed in a separation disc round surface of an axle flow cycloid hydraulic motor. In comparison with the axle flow cycloid motor separation disc and manufacturing process in the prior art, the oil passing area of the separation disc is increased by the improved structure, and the gap at the flow valve engagement axle hole of the coaxial flow structure lowers possible leakage, reduces the pressure loss and improves the efficiency of products.

Description

technical field [0001] The invention relates to a spacer hole, in particular to a cycloidal hydraulic motor spacer oil through hole, and also relates to a processing method thereof, 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 is a low-speed high-torque motor, which has the advantages of small size, high unit power density, high efficiency, and wide speed range, so it has been widely used. [0003] Shaft distribution The flow distribution mechanism of the cycloidal hydraulic motor is located in the radial distribution of the flow distribution shaft of the output shaft and the distribution hole of the body shell that cooperate with each other. Different numbers of distribution holes are distributed. The e...
