MODELING, DESIGN, DEVELOPMENT, TESTING & ANALYSIS OF DUAL WORM SELF LOCKING SYSTEM FOR IMPROVED TRANSMISSION EFFICIENCY & DECELERATION LOCKING PROPERTY
Keywords:
Worm Pair,, Self locking, Transmission efficiency, back drivingAbstract
In many cases wherever material handling equipment gear drives are used because of their efficient transmission of power. But disadvantage of this system are whenever power shut down occurs or may be mechanical failure occurs are input side of the system. If this situation occurs, guarantee of rotation of the shaft cannot be predicted. It can move in both the direction, either it can continue moving in same direction because of inertia or it may move in opposite direction because of gravity of the load. Moving in the reverse direction is also called as back driving [1]. To prevent back driving self locking gears can be provided, which doesn’t move in opposite direction.
