SYNOPSIS
The main concept of the proposed system is nut fitting & removing without human help for driving. The heart of the project is motor.. The components used here for efficient function of individual blocks are Motor, Nut fitting arrangement (spanner) and spur gear arrangement.
WORKING PRINCIPLE
The project has to give the positive & negative potential to the motor. If we push the corresponding switch for forward rotation, it helps to fix the nut, or else if we push the corresponding switch for reverse rotation, the given polarity will be changed oppositely and it helps to remove the nut. The motor can be operated according to the operator’s requirement. The electric power can be given by the battery. The operator should lift the model and place at the appropriate place to tighten or remove the nut.
ADVANTAGES
Advantages from this system is
Simple in size
Less weight
Low power consumption
Can be operated easily
DISADVANTAGE
It is difficult to remove if rust is formed since it requires high torque to remove nut.
APPLICATIONS
It is applicable in automobile workshops.
