ABSTRACT
In modern days the availability of the energy in terms of Electricity is the major and challengeable problem which is facing by all of us. This project aims to reduce that difficulty. It also reduces the labour cost and increases the productivity by reducing the time. This project aims in designing and fabricating the fan model which operated by clock spring and spur gear arrangement. This project is utilizing the mechanical energy which is stored in the clock spring instead of using the electrical energy. The main aim of this project is, To require the best practical knowledge in designing and constructing a machine. The practical difficulties are found in a sequential order and the corrective action is taken to overcome the problems. This project work is concerned with the fabrication of a “SPRING LOADED FAN” which is useful to do various operations in sheet metal industries. This machine reduces the production time and it is practicable any design required can be attained easily by this machine.
To fabricate a Fan operated by utilizing mechanical energy stored in the spring.
