MODELING, DESIGN, DEVELOPMENT, TESTING & ANALYSIS OF DUAL WORM SELF LOCKING SYSTEM FOR IMPROVED TRANSMISSION EFFICIENCY & DECELERATION LOCKING PROPERTY

 In many cases wherever material handling equipment gear drives are used because of their efficient transmission of power. But disadvantage o f this system are whenever power shut down occurs or may be mechanical failure occurs are inpu t side of the system. If this situation occurs,guarantee of rotation of the shaft cannot be predic ted. It can move in both the direction,either it can continue moving in same direction because of in ertia or it may move in opposite direction because of gravity of the load. Moving in the rever se direction is also called as back driving [1]. To prevent back driving self locking gears can be p rovided,which doesn�t move in opposite direction. The project implemented aims at self locking proper ty by usage of worm pair which are connected to each other in mesh pattern. The advant age of implemented system is simple and robust in construction. And we can achieve efficien cy of around 90%,where as conventional system has efficiency of only 40%.
