The equipment ratio of the worm gear established is determined by dividing the variety of enamel of the equipment by the number of threads. Consequently, single thread yields higher ratios than multithreading. All ep worm gear bushings have remaining or correct thread. ep worm gear sets are available in solitary, double, triple and quadruple threads.
Security PROVISIONS: Worm drives should not be used as a locking system to safe large objects, which may cause harm or injuries in the course of reverse action. In non-potentially hazardous programs, self-locking is necessary to stop reverse rotation, and then a lower-pitch one-threaded worm is used to instantly lock the worm equipment to avert reverse rotation.
