The invention discloses an outer rotor double-support traction machine. The outer rotor double-support traction machine comprises a machine base, a rotor rotating shaft, a bearing mounting seat, a traction wheel, a rear bearing, a hub, a stator and a front bearing, wherein the rear bearing is installed between the machine base and the rear end of the rotor rotating shaft; the hub is fixedly installed on the rotor rotating shaft; the stator matched with the hub and fixedly installed on the machine base; the front bearing is installed between the bearing mounting seat and the front end of the rotor rotating shaft; the stator is located on the front side of the front bearing; the hub comprises a rotor which is located on the front side of the front bearing and surrounds the stator, and a fixing part which is located between the front bearing and the rear bearing and is fixed to the rotor rotating shaft; the traction wheel is fixedly installed on the fixing part through a fixing piece; and the inner diameter of the traction wheel is larger than the outer diameter of the front bearing. Compared with the prior art, the bearings do not need to be dismounted when the traction wheel is dismounted, and dismounting is convenient. The invention further discloses a corresponding traction wheel dismounting method.
