内外双排力偶型径向柱塞马达泄漏分析与试验

摘要/Abstract

摘要： 为了延长径向柱塞马达的寿命，设计了基于力偶原理的新型马达。力偶型马达的形成受马达柱塞数和凸轮环导轨曲线作用数的影响，通过分析马达柱塞数和导轨曲线作用数之间的关系，确定了形成力偶型马达的条件。马达在工作过程中存在相对运动的摩擦副，而相对运动的摩擦副处会产生油液的泄漏。以内马达为例，通过对柱塞在缸体中的径向运动产生泄漏和配流盘配流产生泄漏的分析，确定两处的泄漏公式。对马达原理进行了试验，验证了力偶型径向柱塞马达原理的正确性。

Abstract: In order to extend the life of radial piston motors, a novel moter was designed based on principle of force couple. The formation of the coupler type motors was affected by the number of motor plungers and the number of cam ring guide curves. By analyzing the relationship between the number of motor plungers and the number of rail curve effects, the conditions under which the coupler motor might be formed were determined. The motor has a relatively moving friction pair in operations, and the relative movement of friction pair causes oil leakage. Taking the inner motor as an example, the leakage formula of the two places was determined by analyzing the leakage of the plunger in cylinder and the leakage of the distribution plate. The principle of the motor was tested to verify the correctness of the principle of the force-coupled radial piston motors.

Key words: fluid drive and control, internal and external double-row, force couple hydraulic motor, leakage analysis, principle test
