The primary edge of worm gears is their capacity to provide higher reduction ratios and correspondingly higher torque multipliers. They can also be employed as reducers for minimal to medium velocity apps. Also, due to the fact their reduction ratio is based mostly on the variety of enamel on the equipment, they are more compact than other types of gears. Like good pitch leadscrews, worm gears are usually self-locking, generating them perfect for hoisting and hoisting applications.
Protection PROVISIONS: Worm drives should not be employed as a locking mechanism to protected heavy objects, which could result in harm or damage throughout reverse action. In non-potentially dangerous applications, self-locking is needed to avert reverse rotation, and then a low-pitch one-threaded worm is utilized to immediately lock the worm gear to prevent reverse rotation.
