ELECTRIC SCREW JACK

Presentation

Introduction A jack is a mechanical device used to lift

heavy loads or apply great forces. It is a design for lifting cars, vehicles etc. A mechanical jack is a device which lifts

heavy equipment. Car jacks usually use mechanical

advantage to allow a human to lift a vehicle by manual force alone.

The motors used in this project are D.C. motors.

The conversion of electrical energy into mechanical energy by a electromagnetic means is demonstrated by the British scientist Michael Faraday in 1821.

Jedlik's "electromagnetic self-rotor", 1827. (Museum of Applied Arts, Budapest. The historic motor still works perfectly today.)

A screw jack is a mechanical device that can increase the magnitude of an effort force.

A jackscrew is a type of jack which is operated by turning a leadscrew.

THE STUDY AREA

The main area for this study is to choose the best deisgn possible for the lifting mechanism and to install the electric motor interface with the jack

A 30 rpm DC Geared motor for the design due to its high torque and sufficiently high power to lift the jack up and down.

LIST OF COMPONENTS USED

Base Plate Springs Pillar Blocks Linear Actuator Nut-Bolt Pair DC Geared Motor Battery 6V Rectangular Plates

Switches for remote PCB for remote Allen Bolts ( 5X10,5x16,4x10 ) Collars ( OD=25, ID=12) , thick=15 Mechanical Framework for whole project

Objective

The aim of our project is to design an electric jack to lift the vehicle with the help of electric current through a motor (dc geared)

Thus this project helps in replacing the mechanical jacks used in industries with more easily operated and reliable electric jack.
