Totally-closed gear motor

The utility model discloses a totally-enclosed gear motor, which comprises a shell, partition plates mounted on an inner cavity of the shell, a motor main body mounted between the partition plates, an output shaft and an auxiliary shaft mounted at two ends of the motor main body respectively for output and auxiliary transmission, air inlet pipes mounted at the top and the bottom of the shell, and an air outlet pipe mounted at the tail end of the shell. The inner cavity of the shell can be ventilated through the arranged ventilation pipe, the ventilation pipe can be ventilated and cooled through the heat removal fan and the high-speed fan, ventilation can be blown to the heat dissipation box through rotation of the heat dissipation fan, and then rapid heat dissipation is achieved through the heat dissipation fins on the heat dissipation box. The spiral pipe can circularly cool through the arranged circulating cooling box to absorb heat and dissipate heat so as to improve the heat dissipation capacity, and the
