Abstract
The utility model provides a speed reduction motor with a differential function. The speed reduction motor comprises a motor and a planetary speed reduction box integrally connected with the motor through a shaft. The motor is composed of a stator (20), a rotor (21), a drive cover (16), a case (19) and an end cover (22). A drive shaft of the motor is a hollow shaft. The motor further comprises a differential (3), a turntable (9) and a supporting sleeve (8). One end of the turntable (9) is connected with the last level of planet gear of the planetary speed reduction box through a mandrel (10). The turntable (9) is fixed on the differential (3) by a screw I (4) through the supporting sleeve (8). A flange (1) is arranged at the outer end of the differential (3) by making use of a bearing I (2). The flange (1) is fixedly connected with the drive cover (16) of the motor through a screw II (5). The speed reduction motor with the differential speed function has the advantages of compact structure, small size and convenient installation.
