法国海特罗兰德(HYDROLAND)公司近年来制成一种结构新颖的摆缸式径向油马达。它属于大扭矩、等排量型,轴转、可反向,也可制成两对称输出轴,采用摆动耳轴配流。一、结构和工作原理 1.结构海特罗兰德油马达的结构见图3。结构尺寸相同的两壳体靠三根弹性销定位,用螺栓固紧,壳体上有进、出、泄油和排气等四孔。进、出油口与环形油道相通。曲轴由三个轴承支承,曲拐处装有滚针轴承,采用两段装配结构,由三根弹性销保证定位精度,装配后一般都将弹性销焊死。柱塞为光身柱
In recent years, HYDROLAND has made a new type of radial piston motor. It belongs to high torque, equal displacement type, shaft rotation, can be reversed, can also be made of two symmetrical output shaft, the use of swing trunnion with flow. First, the structure and working principle 1. Structure Heterodendron oil motor structure shown in Figure 3. The two structural shells of the same size are positioned by three elastic pins, which are fastened with bolts. There are four holes on the shell, such as inlet, outlet, drain and exhaust. Into and out of the oil port and the annular oil passage. The crankshaft is supported by three bearings. There are needle roller bearings on the crank. The two-stage assembly structure is adopted. The three elastic pins ensure the positioning accuracy. Generally, the elastic pins are welded to each other after assembly. Pistons for the light body column
