【摘要】 针对现有液压执行元件只能实现单一的往复直线运动或旋转运动,提出了一种新的液压执行元件———旋转推进液压缸.将传统叶片式液压马达和液压缸两种执行元件进行耦合,以液压马达的回旋运动部件取代液压缸体内的活塞部分,在同一液压源的作用下,在单一缸体内用两条油路就能实现具有负载能力的往复推进和旋转的复合运动.由于复合运动基于同一液压源,缸内的液压油可自动实现柔性的流量分配,使液压缸输出的旋转往复运动具有弹性进给和能量互补的优良的自适应特性.更多还原

【Abstract】 Aimed at the linear reciprocating motion or rotary movement of the existing hydraulic actuators,a new hydraulic actuator of rotary propulsion hydraulic cylinder was proposed.Coupled with the traditional vane hydraulic motor and hydraulic cylinder,hydraulic motor turning movement parts we used to replace hydraulic piston in the cylinder part.In the same action of hydraulic source,the reciprocating propulsion and rotating combined motion with load capacity was realized in a single cylinder with two oil circuit.Because of the combined motion based on the same hydraulic source,the hydraulic oil in the cylinder can automatically realize soft flow distribution.The result show that the rotation reciprocating motion of hydraulic cylinder has the features of good adaptive characteristics in elastic feed and energy complementary.更多还原
