Abstracts: The title of project is a live case study of worm reduction gearbox. The main purpose of case study is to find out the reason why the gearbox is worn out before its estimated life. Main parts of elevator system are gearbox , rope and an electric motor which helps to moves people or goods between floors of building , vessel or other structure. The elevator turns electric power to mechanical power. Worm gear is used because of its properties like high torque and low speed. In our project we will study and observe the life of bearing, shaft life and worm life. And we also calculate the force acting on worm gear pair and motor power required for machine.
