3. ABSTRACT
Now a days lack of energy availability is one of the main problem facing us
This fan can be rotated without the application of impact force
In our project the spring loaded fan is very simple in operation by using spur gear arrangement

4. INTRODUCTION
The aim of the 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 operation time and it is practicable any design required can be attained easily by this machine.

6. OBJECTIVES To build a spring loaded fan with the help of spring
To understand about spur gear mechanism
To know about leaf spring mechanism

7. WORKING PRINCIPLE
The handle is used to rotate the spring in forward direction. The spring coupled with the main shaft with suitable arrangement.
The shaft is used to loading the spring. One end of the main shaft is coupled with the handle arrangement and other side is fixed to the big gear wheel arrangement.
 The big gear wheel is engaged to another small gear wheel with the help of spur gear mechanism. This mechanism is used to increase the speed of the fan. In our project, the leaf is coupled to this small gear wheel arrangement with the help of suitable arrangement.
The fan leaf is made up of the light weight material such as fiber, plastic or nylon material.

9. EXPECTED CONCLUSION
To build a model of spring loaded fan by spring and spur gear arrangement
This model is efficient way to conserve energy
