谐波液压马达是一种新型的多作用大扭矩液压马达。这种液压马达在要求低速大扭矩的不带减速机构的装置中使用很有前途。谐波液压马达的工作原理(图1)如下。工作油液沿配流轴和缸体中的通道进入装设在缸体中的可以产生径向位移并与柔轮内表面相互作用的柱塞之下。配流轴与装有两只滚轮的转臂刚性连接。滚轮使柔轮变形而在沿直径相对的两个区域中形成柔轮变形波峰,柔轮轮齿完全进入刚轮齿槽,而在另外两个沿直径相对的区域里则完全脱离啮合。因为转臂中心线与配流轴的进油通道错开一个α角,在柱塞腔油液
Harmonic hydraulic motor is a new type of multi-role high torque hydraulic motor. This type of hydraulic motor is promising for use in devices that do not require a reduction gear mechanism that requires low speed and high torque. Harmonic hydraulic motor working principle (Figure 1) is as follows. Working fluid flows along the flow distribution shaft and the passageway in the cylinder below a plunger mounted in the cylinder that creates a radial displacement and interacts with the flexspline inner surface. The distribution shaft is rigidly connected to the boom with two rollers. The rollers deform the flexspline to form flexural deformation peaks in diametrically opposed two regions, the flexspline teeth entering the gear slot completely and disengaging completely in the other two diametrically opposed regions. Because the boom centerline and the inlet axis of the oil channel staggered by an angle α, in the plunger cavity fluid
