Abstract
Description
Technical Field
[0001] This utility model relates to the field of worm gear structure technology, specifically a shock-absorbing worm gear. Background Technology
[0002] A worm gear is a gear with one or more helical teeth that meshes with a worm wheel to form an interlocking gear pair. In general worm gear drives, the worm is the driving element. During operation, the worm wheel teeth slide and roll along the helical surface of the worm. Current technology requires extremely high precision for the worm shaft and gear sleeve. If a precision deviation occurs, high-frequency vibration will occur when the worm shaft and gear sleeve rotate out of sync. This is more likely to happen with long worms, especially at the joints at both ends of the gear sleeve, affecting the operation of the equipment and production quality. Utility Model Content
