摘要
介绍一种供牵引电机装拆、维修用的液压设备的结构原理，及其液压系统的特点和三铰点液压变幅机构的ＣＡＤ设计法。其液压变幅机构输出载荷大，可使电机的内部和五个外部表面上的检修在该设备上一次完成。
This article presents the construction and the principle of the hydraulic tumbling machine for assembly and maintenance of the traction electrical motor, the property of the hydraulic system, the design of three hinge points of hydraulic amplitude-change mechanism and the calculation of load bearing fork.
