Specific implementation mode
Embodiment one：
As shown in Fig. 1, a kind of three-bearing machine speed reducer assembly structure, including motor assembly and retarder 1；The motor is total
At including motor shaft 2, rotor 3, motor stator 4 and electric machine casing 5；The front end spline of the retarder 1 and motor shaft 2
Connection；The retarder 1 is internal spline, and motor shaft 2 is external splines；The rear and front end end of the retarder 1 is connected separately with
Bearing 7 after retarder fore bearing 6 and retarder；It is provided with bearing chamber in the electric machine casing 5, for placing a motor bearings
8；The motor bearings 8 is connect with the rear end of motor shaft 2；It is provided with transition cooperation section 9 in one end on the motor shaft 2, and subtracts
1 transition of fast device cooperation is used as auxiliary positioning；The electric machine casing 5 and the boundary of retarder 1 are provided with oil sealing 10, the oil sealing
10 for preventing the lubricating oil of retarder 1 from entering inside motor assembly；The oil sealing 10 is mounted on motor shaft 2.
Embodiment two：
As shown in Fig. 2, a kind of three-bearing machine speed reducer assembly structure, including motor assembly and retarder 1；The motor is total
At including motor shaft 2, rotor 3, motor stator 4 and electric machine casing 5；The front end spline of the retarder 1 and motor shaft 2
Connection；The retarder 1 is external splines, and motor shaft 2 is internal spline；The rear and front end end of the retarder 1 is connected separately with
Bearing 7 after retarder fore bearing 6 and retarder；It is provided with bearing chamber in the electric machine casing 5, for placing a motor bearings
8；The motor bearings 8 is connect with the rear end of motor shaft 2；It is provided with transition cooperation section 9 in one end on the motor shaft 2, and subtracts
