Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:
[0023] Such as figure 1 , figure 2 As shown, a coupling for an electric bus motor, which includes a body 1, a flange 2 arranged at the end of the body 1, and a stepped through hole arranged in the axial direction, the through hole is on the same side as the flange 2 One end is the shaft fastener accommodating cavity 3, and the side of the through hole away from the flange 2 is a tapered hole 4 whose inner diameter gradually decreases from the outside to the inside. Two key grooves 5 arranged in the axial direction are arranged symmetrically about the symmetrical center line. The structure of the tapered hole 4 increases the contact area between the coupling and the connecting shaft, improves the coaxiality between the connecting shaft and the coupling, has good balance performance, and thus enhanc...
