Abstract

A transmission device includes an input shaft, a first transmission mechanism, a speed changing mechanism, and an output shaft. The first transmission mechanism includes a transmission shaft, an inner magnetic member received in the transmission shaft, a mounting housing coupled to the input shaft, and an outer magnetic member. The input shaft is configured to rotate the mounting housing. The outer magnetic member is received in the mounting housing and positioned adjacent to the inner magnetic member. A magnetic pole of the inner magnetic member is opposite to a magnetic pole of the outer magnetic member. The speed changing mechanism is coupled to the transmission shaft. The output shaft is coupled to the speed changing mechanism.
