[0002] At present, the reduction mechanism of the door opener includes a worm gear reduction mechanism, which uses the meshing transmission of the worm and the worm wheel to achieve reduction. The worm is usually the active part and the worm wheel is the driven part. When the worm rotates, the friction force of the tooth surface drives the worm wheel to rotate. Since the number of teeth of the worm is generally small, and the number of teeth of the worm wheel is large, the reduction effect is achieved.
