近年我厂试制了一种单作用摆缸式大扭矩径向油马达WJM—F0.55。这种油马达仍属于静力平衡油马达,但于连杆式、五星轮式静力平衡油马达比较,其最大特点是柱塞缸体组件随油马达运转不仅作相对往复运动,而且油马达每转一转在±12°之间往返摆动一次。因此,这种油马达既保留静力平衡油马达的一切优点,又具有独特的优点。径向油马达的摆缸结构,国内比较少见,而国外已经出现了多种型式。主要有球面支承、球铰轴承、耳轴铰接三种。WJM-F0.55 In recent years, I plant trial production of a single-acting swing cylinder type large torque radial oil motor WJM-F0.55. This oil motor is still a static balance of oil motor, but the link, five-wheel wheeled static balance oil motor, the most significant feature is the plunger cylinder assembly with oil motor operation not only for reciprocating motion, and oil motor Swing between ± 12 ° for each revolution. Therefore, this oil motor not only retains all the advantages of static balance oil motor, but also has unique advantages. Radial oil motor swing cylinder structure, relatively rare in China, and abroad, there have been many types. There are three main spherical bearings, spherical hinge bearing, trunnion articulation.
