The invention relates to a friction wheel driving mechanism. A friction wheel supporting base rotating around a driving shaft through a bearing component A is arranged at one end of the driving shaft, an output shaft horizontally penetrating through the friction wheel supporting base is arranged at the lower end of the friction wheel supporting base, and the two ends of the output shaft are each provided with a friction wheel; a pressing mechanism is arranged on a base, and the front end of the pressing mechanism is connected with the lower end of the friction wheel supporting base, and a driving motor serves as a rotating mechanism and is connected with the driving shaft through a chain. The friction wheel driving mechanism has the advantages that the driving motor drives the driving shaft, then drives the output shaft to rotate through a synchronous belt and finally drives the friction wheels to rotate, and then the frictions wheels are adjusted through stretching and retracting of the pressing mechanism to be attached to a device needing transmission to achieve transmission; a universal joint bearing can adjust the angle without rotating, and the bearing can play a role in angle supporting when a roller and the friction wheels are not in the ideal state, for example when a small angle exists.
