1results about How to "Large gear ratio" patented technology

This utility model relates to the field of pipe fitting elbow adjustment technology, specifically a steel pipe fitting elbow angle adjustment device, including a base. Mounting plates are fixedly connected to both the front and rear ends of the base. A rotating assembly is installed inside the base, comprising a first motor fixedly mounted on the right side of the base. A worm gear is fixedly connected to the rotating shaft of the first motor, and the left side of the worm gear is engaged in a first fixed sleeve. A second fixed sleeve is fixedly connected to the lower middle position inside the base, and a rotating rod is inserted into the upper end of the second fixed sleeve. A worm wheel is sleeved on the rotating rod. The meshing transmission ratio of the worm and worm wheel is large, converting the high-speed rotation of the first motor into low-speed, high-precision rotation of the rotating rod, meeting the high-precision requirements of aerospace, nuclear power, and other industries. The self-locking characteristics of the worm wheel and worm gear ensure that the angle will not shift due to external force after the machine stops, improving stability.
