Abstract
The utility model relates to a bidirectional coaxial worm gear speed reducing motor, which is characterized in that output shafts are arranged at both ends of the speed reducing motor, and the speed reducing motor not only is coaxial, but also can synchronously output power. A rotary shaft of a motor rotor in the speed reducing motor is a through-holed shaft, and a worm is arranged at a larger end of the through-holed shaft. When rotating, the rotor drives a worm gear, a bevel gear set, a large spur gear and a small spur gear in a worm gear speed reducing box to decelerate the output shafts which are coaxial with the large spur gear and fixed onto the large spur gear. Simultaneously, the output shafts are also coaxial with the motor rotor and penetrate through the through-holed shaft on the rotor. The worm gear speed reducing box and an electrical control box are respectively positioned at two axial ends of the motor and integrated with the motor. The output shafts extend out of two ends of the worm gear speed reducing box and two ends of the electrical control box, so that the functions of bidirectional, coaxial and synchronous power output after deceleration can be realized.
