Speed-reduction motor

The utility model relates to a speed-reduction motor, and the speed-reduction motor comprises a speed reducer and a motor. The motor comprises a motor body, a rotating shaft, a motor front cover, and a motor housing. The speed reducer comprises a bearing plate, a speed reducer body, and a speed reducer housing. The motor is characterized in that the motor is connected with the speed reducer housing through that the motor front cover and the bearing plate of the speed reducer are connected through a first bolt; One end, connected with the speed reducer, of the rotating shaft is provided with an involute tooth. The speed reducer and the motor are engaged with each other through a gear for the transfer of torque. One end, connected with the speed reducer, of the rotating shaft is provided with the involute tooth, and the speed reducer and the motor are engaged with each other through the gear for the transfer of torque, thereby replacing a mode that a conventional motor rotating shaft achieves the transfer of torque through the connection of a key slot with the gear, and enabling the transmission to be stable and the vibration to be small. The motor is in bolt connection with the speed reducer, so the motor is convenient in installation and disassembly.
