ABSTRACT

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.
