The invention discloses a monorail driving unit. The monorail driving unit comprises a motor and a gear box, the gear box is of a speed reduction structure of a planetary speed reduction mechanism, the motor and the gear box share the same box body, the box body comprises a front box body and a rear box body, one part of the front box body is used for forming a motor shell, and the other part of the front box body and the rear box body jointly form a gear box shell. Preferably, the motor shell also comprises a water cooling wall and a front box cover, and water cooling channels are arranged onthe water cooling wall and the front box body; the motor comprises a stator and a rotor fixed on a rotor inner core, and two ends of the rotor inner core are rotatably supported on the front box cover and the front box body respectively; the rotor inner core is of a hollow structure, a gear shaft is arranged in the rotor inner core in a penetrating mode, and the rotor inner core and the gear shaft are connected in a spline fit mode. The gear shaft forms a sun gear of the planetary reduction mechanism. The monorail driving unit has the beneficial effects of compact layout, small structural size, light weight, sufficient cooling of the motor and the gear box, good heat dissipation effect, large output torque and long service life.

    本发明公开了一种单轨驱动单元,包括电机和齿轮箱;齿轮箱采用行星减速机构的减速结构,且电机和齿轮箱共用同一个箱体,箱体包括前箱体和后箱体,前箱体的一部分用于构成电机壳体,另一部与后箱体共同构成齿轮箱壳体。优选,电机壳体还包括水冷壁和前箱盖,水冷壁和前箱体上设有水冷通道;电机包括定子和固定在转子内芯上的转,转子内芯两端可转动地分别支撑在前箱盖和前箱体上;转子内芯呈空心结构,转子内芯内穿设有齿轮轴,转子内芯与齿轮轴之间通过花键配合连接;齿轮轴构成行星减速机构的太阳轮。本发明的有益效果是,布局紧凑,结构体积小,重量轻,电机和齿轮箱冷却充分,散热效果好,输出扭矩大,使用寿命长。
