Abstract
This utility model discloses a large torque rotation driving device, comprising a substrate, a rotation support and a worm. The substrate consists of a shaft housing and a substrate ring. The axial lead of the shaft housing is perpendicular to the axial lead of the substrate ring; the worm is arranged within the shaft housing of the substrate; an inner ring and an outer toothed ring of the rotation support are provided with a plurality of installation screw holes; the inner ring is fixed above the substrate ring; and the outer toothed ring is meshed with the worm. The large torque rotation driving device is characterized in that three to eight positioning pins are arranged between the inner ring and the substrate ring. In the large torque rotation driving device, the number of the positioning pins is increased, which on one hand increases the positioning accuracy of the installation and on the other hand increases the lateral anti-shearing force of the positioning pins, and thus increases output torque of the rotation driving device. The large torque rotation driving device is simple in structure and reasonable in design and satisfies the requirement for the rotation driving device to bear large torque on special occasions.
