The invention discloses a high-reliability precise driving device which comprises a shell, a servo motor, a transmission mechanism and an angle sensor, wherein the driving device adopts a mechanical-electrical integration design; the transmission mechanism is a novel less differential gear reducer; output transmission errors are sent to the servo motor through the angle sensor so that the transmission mechanism is complementally driven; particularly, the transmission mechanism organically combines a conical eccentric cam and an arc spiral conical gear into a non-backlash precise transmission pair which can self-adaptively compensate tooth surface wear; and a solid lubricating film is coated on an engaging surface of the transmission pair, thus under special and extreme environment, the engaging tooth surface can generate moderate elastic deformation and effectively prevent and eliminate jamming or blocking of the transmission. The high-reliability precise driving device has the advantages of high rigidity, high precision, high reliability, long service life, large torque, low energy consumption, small volume, light weight, free maintenance, and the like, and can be widely applied to equipment in the fields of robot engineering, automotive engineering, vehicle engineering, aeronautical engineering, aerospace engineering, and the like.
