In almost every material handling equipment gear drives are used. In these type of systems when the driving torque is suddenly decreased due to mechanical failure, power off or any kind of failure at the input shaft of the system, then gears will be start rotating either in the same direction driven by the system inertia, or it will start rotating in the opposite direction driven by the resistant output load due to spring load, gravity, etc. This condition is also known as back driving. But, there is solution in gear transmission that stop inertial motion or back driving using self-locking gears without any extra device. Self-locking is the potential of gear system which constitute a drive which gives the input gear the independence to rotate the output gear in any directions but the output gear locks with input when an outside torque try to rotate the output in any direction. Worm gear pair is self-locking gear pair but it have very low efficiency nearly 40%, when made self-locking. Self-locking feature is obtained by using worm pair which is in mesh with each other. The efficiency nearly 90% can be obtained as compared to 40% of conventional worm gear system.
