针对液压马达径向受力不平衡的问题
提出了一种多工况下双定子多作用力偶液压马达
并采用高次曲线设计了四作用力偶液压马达内、外定子的轮廓线。单作用的定子轮廓线由大、小两段圆弧和两段过渡曲线组成; 多作用力偶液压马达的内、外定子轮廓线由多个等宽、相似的单作用定子轮廓线组成
该轮廓线光滑且完全封闭。通过液压马达排量的计算和分析发现:多作用力偶液压马达的排量主要取决于内、外定子轮廓线的半径
定子环的有效宽度
滚柱连杆组的数目
连杆的厚度和马达在一个工作周期内密闭容积吸油及排油的次数。在输入流量不变的情况下
通过改变液压马达的连接方式可以实现内马达单独工作
外马达单独工作
内、外马达同时工作
以及内、外马达差动工作。
Aiming at unbalanced radial force of hydraulic motor
a double-stator multi-acting couple hydraulic motor under various operating conditions is proposed
and the inner and outer stator contours of a four-acting couple hydraulic motor are designed with higher order curves. The stator contour of a single-acting contains long and short circular arcs and two transition curves
and the inner and outer stator contours of a double-stator multi-acting couple hydraulic motor are made up by several similar single-role stator contour lines
which are smooth and completely closed. It is found that the calculated displacement of the double-stator multi-acting couple hydraulic motor usually depends on the inner and outer contour radius
effective width of stator ring
number of roller group
thickness of connecting rod and times of closed volume oil suction/discharge during operating period. For unchanged input flow
the inner motor and outer motor can operate separately
simultaneously or differently by adjusting the connecting modes.
