Hydraulic motor cylinder body oil distributing disc assembly and processing method thereof

Abstract

The invention discloses a hydraulic motor cylinder body oil distributing disc assembly which comprises a plunger cylinder body and an oil distributing disc, wherein the plunger cylinder body comprises a cylinder main body and sintered copper, the sintered copper is sintered on the cylinder main body, a connecting rod accommodating cavity is arranged at the center of the plunger cylinder body, a plunger accommodating cavity is arranged at the periphery of the connecting rod accommodating cavity and is communicated with an oil distributing channel arranged on the oil distributing disc through a cylinder oil path, a vibration reducing groove is formed in the oil discharging channel, the cylinder body oil path is uniformly distributed around a circumferential direction of a cylinder body washing oil path; an oil distributing disc positioning pin hole and an oil distributing disc washing oil path are formed in the oil distributing disc; in addition, a left process conical surface and a right process conical surface are arranged on the oil distributing disc. The hydraulic motor cylinder body oil distributing disc assembly has characteristics of abrasion resistance, corrosion resistance and impact resistance, and is high in processing precision; oil distributing disc assemblies are assembled according to given assembling gaps and sizes, so that the noise generated when a hydraulic motor runs is reduced, and the transmission performance of all the assemblies can be ensured; an assembly guide is provided, so that assembled parts are prevented from being damaged, and the service life of the assemblies is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic system actuators, in particular to a hydraulic motor cylinder oil distribution plate assembly and a processing method thereof. Background technique [0002] In the axial piston hydraulic motor, the oil distribution mechanism is one of the key components of the hydraulic motor. Whether its structure, size and machining accuracy are reasonable or not directly affects the working reliability, volumetric efficiency and service life of the hydraulic motor. At present, the oil distribution mechanism mainly adopts the planar flow distribution type, that is, the oil distribution plate is installed on the end face of the cylinder body along the axial direction, and is closely matched with the end face of the cylinder body to complete the oil inlet and discharge, and then convert the hydraulic energy into mechanical energy; this assembly Defects in the method: each part is prepared separately and directly...

AI Technical Summary

Problems solved by technology

At present, the oil distribution mechanism mainly adopts the planar flow distribution type, that is, the oil distribution plate is installed on the end surface of the cylinder body along the axial direction, and closely cooperates with the end surface of the cylinder body to complete the oil inlet and outlet, and then convert the hydraulic energy into mechanical energy; this assembly Defects in the method: each part is prepared separately and directly assembled, and the spherical surface is not matched one by one to remove the processed burrs. The consequence is that the assembly gap is too large, and the noise generated during operation is large, which not only causes environmental pollution , and also affects the transmission performance between various components; if the equipment gap is too small, it will directly cause damage to the internal components of the hydraulic motor and cause failure; at the same time, there is no assembly guide during the assembly process, which may easily cause damage to the assembly parts
