worm gear
Author:
A worm gear refers to a gear that has one or more helical teeth and meshes with a worm wheel to form a crossed-axis gear pair. Its pitch surface can be cylindrical, conical, or annular, and there are four categories: Archimedean worm, involute worm, normal straight profile worm, and conical enveloping cylindrical worm. Transmission Structure Worm drive consists of a worm and a worm wheel, used to transmit motion and power between crossed axes, typically with a crossing angle of 90°. In general worm drives, the worm is the driving component. In appearance, the worm resembles a bolt, while the worm wheel looks like a helical cylindrical gear. During operation, the teeth of the worm wheel slide and roll along the helical surface of the worm. To improve the contact condition of the teeth, the worm wheel is made into an arc shape along the tooth width direction, allowing it to partially envelop the worm. This way, the engagement between the worm and worm wheel is line contact rather than point contact.
