摘　　要：为了解决双定子多速马达叶片尖端对内、外定子曲线的磨损及径向间隙补偿的问题,提出了一种新型的滚柱叶片式结构,该结构将叶片尖端与定子曲线间的滑压变为滚压,并依靠工作中产生的离心惯性力与液压力,将滚柱分别与内、外定子曲线压紧,形成密封容积。对4种不同工况下的双定子多速液压马达进行了受力分析,同时搭建实验台对双定子多速马达样机进行了测试。结果表明,滚柱叶片式结构能够在实现滚压的同时保持容积效率,转移了叶片尖端与定子曲线间的矛盾,为双定子多速液压马达的设计提供了一个新的思路。In order to diminish the frictional force between the vane tips and the stators and achieve the clearance compensation, a novel double-stator multi-speed motor with roller vane tips was proposed, in which the vane tips roll instead of sliding on the stators. The vane tip rollers are forced on the inner and outer stators under centrifugal force and the hydraulic pressure, thus forming oil tight working chambers. To demonstrate the mechanism of its sealing, force analysis was carried out on the rollers, and the experimental platform was set up. It turned out that the roller-vane structure could acquire rolling while maintain the volumetric efficiency, which transfer the contradictions between the vane tips and the stator curves and provides a new idea for designing the double-stator multi-speed motor.
