底速马达 新疆耐用的液压马达 欢迎来电咨询

工作原理，当压力油经固定的配油轴4的窗口进入缸体内柱塞的底部时，柱塞向外伸出，紧紧**住定子的内壁，由于定子与缸体存在一偏心距。在柱塞与定子接触处，定子对柱塞的反作用力为 。力可分解为和 两个分力。当作用在柱塞底部的油液压力为p，柱塞直径为d，力和之间的夹角为X时，力对缸体产生一转矩，使缸体旋转。缸体再通过端面连接的传动轴向外输出转矩和转速。以析的一个柱塞产生转矩的情况，由于在压油区作用有好几个柱塞，在这些柱塞上所产生的转矩都使缸体旋转，并输出转矩。径向柱塞液压马达多用于低速大转矩的情况下。
液压马达是液压系统的一种执行元件，它将液压泵提供的液体压力能转变为其输出轴的机械能(转矩和转速)。液体是传递力和运动的介质。液压马达，亦称为油马达，主要应用于注塑机械、船舶、起扬机、工程机械、建筑机械、煤矿机械、矿山机械、冶金机械、船舶机械、石油化工、港口机械等。

但是，由于液压马达和液压泵的工作条件不同，对它们的性能要求也不一样，所以同类型的液压马达和液压泵之间，仍存在许多差别。首先液压马达应能够正、反转，因而要求其内部结构对称;液压马达的转速范围需要足够大，特别对它的稳定转速有一定的要求。因此，它通常都采用滚动轴承或静压滑动轴承;其次液压马达由于在输入压力油条件下工作，因而不必具备自吸能力，但需要一定的初始密封性，才能提供必要的起动转矩。由于存在着这些差别，使得液压马达和液压泵在结构上比较相似，但不能可逆工作。MR500F-F1N1N1S1NX0701/58323

轴向柱塞泵除阀式配流外，其它形式原则上都可以作为液压马达用，即轴向柱塞泵和轴向柱塞马达是可逆的。轴向柱塞马达的工作原理为，配油盘和斜盘固定不动，马达轴与缸体相连接一起旋转。当压力油经配油盘的窗口进入缸体的柱塞孔时，柱塞在压力油作用下外伸，紧贴斜盘，斜盘对柱塞产生一个法向反力p，此力可分解为轴向分力及和垂直分力Q。Q与柱塞上液压力相平衡，而Q则使柱塞对缸体中心产生一个转矩，带动马达轴逆时针方向旋转。轴向柱塞马达产生的瞬时总转矩是脉动的。若改变马达压力油输入方向，则马达轴按顺时针方向旋转。斜盘倾角a的改变、即排量的变化，不仅影响马达的转矩，而且影响它的转速和转向。斜盘倾角越大，产生转矩越大，转速越低。轴向柱塞泵 E-A4VSO250EO2/30R-VPB25N00-SO3

从能量转换的观点来看，液压泵与液压马达是可逆工作的液压元件，向任何一种液压泵输入工作液体，都可使其变成液压马达工况;反之，当液压马达的主轴由外力矩驱动旋转时，也可变为液压泵工况。因为它们具有同样的基本结构要素--密闭而又可以周期变化的容积和相应的配油机构。卡桑尼马达MR4500L-F1Q2N1N1NX0600/58081
