摆线马达是用于旋转作业机具的部件。 加压液压油用于强制马达转动。 马达可以沿顺时针方向或逆时针方向转动。 这允许作业机具沿任一方向旋转。
加压液压油进入端口 (3) 或端口 (4)。 操作员选择的旋转方向决定油的进入点。 当油进入端口 (3) 时，油从端口流入腔室 (1)。 腔室 (1) 是由转子组 (2) 形成的区域。 加压液压油导致转子组旋转。 回油从腔室 (1) 流入端口 (4)，回到液压油箱。
转子组 (2) 用花键固定到连杆 (6) 上。 连杆 (6) 用花键固定到输出轴 (5) 上。 齿轮 (7) 安装在轴 (6) 上。 齿轮与安装在上壳体和下壳体之间的齿轮和轴承啮合。 当齿轮 (7) 转动时，齿轮和轴承沿相反方向转动。 这导致作业机具的下壳体按照操作员选择的方向旋转。
当选择相反的旋转方向时，油在端口 (4) 处进入马达。 油从端口流入腔室 (1)。 从端口 (4) 进入腔室 (1) 的入口使得油流向相反的方向。 回油从腔室 (1) 流入端口 (3)，回到液压油箱。 方向变化导致作业机具沿相反的方向旋转。

(8) 交叉安全阀 | |
交叉安全阀 (8) 安装在摆线马达上两个端口的顶部。 该阀用于释放马达回路中的过大压力。 油在进入马达之前必须流过控制歧管。 有关更多信息，请参阅维修手册, "控制歧管"。
