The motor also comprises a front bearing 7 and a rear bearing 9 which are of the same size and are respectively arranged in the bearing chambers of the front end cover 3 and the rear end cover 11. The front bearing 7 and the rear bearing 9 are respectively in interference fit with the rotor 8. A wave washer 6 is arranged in the bearing chamber of the front end cover 3.
The motor also comprises a first flat key 5 and a second flat key 10 which are respectively arranged at two ends of the output shaft of the rotor 8. The first synchronous pulley 1 is arranged at one end of the output shaft of the rotor 8 through a first flat key 5, and the second synchronous pulley 12 is arranged at the other end of the output shaft of the rotor 8 through a second flat key 10.
The motor further comprises a wire box 13 containing a wire harness and a wire box mounting screw 14, wherein the wire box 13 containing the wire harness is welded with the stator 4 and is mounted by using the wire box mounting screw 14. The motor also comprises an end cover mounting screw 2, and the end cover mounting screw 2 sequentially penetrates through the front end cover 3, the stator 4 and the rear end cover 11.
The output shafts at the two ends of the motor rotor 8 can be provided with transmission structures such as synchronous pulleys or gears. The two rolling bearings with the same specification are adopted, so that radial forces at two ends are better balanced in motor operation, motor transmission is more stable and efficient, and service life is prolonged. The end covers with the mounting lugs are used at the two ends of the double-output-shaft driving motor to be mounted, the traditional single-end flange fixing mode is changed into the mode that the side surfaces of the two ends are fixed, and shake of the motor caused by unbalanced load is reduced. When the double-output shaft driving motor is installed, the rotor 8 sequentially passes through the rear end cover 11, the stator 4 and the front end cover 3; the end cover mounting screw 2 sequentially penetrates through the front end cover 3, the stator 4 and the rear end cover 11; a wire box 13 containing a wire harness is welded to the stator 4 and mounted using a wire box mounting screw 14.
