Design & Fabrication of Motorized Screw Jack Machine

Abstract

A screw jack is Jackscrew is function  by turning a lead screw. The maximum height of the jack Is adjusted by turning the lead screw. It can be done either manually or by Integrating an electric motor with it. This integration is our project. It is  difficult part in the project is finding a minimum speed motor that is able to work at 12V. Due to this reason the battery output of an automobile is 12V, and-the electricity needed for the operation of the screw jack Is taken from this battery. Another problem will be regarding speed reduction. 12V motors usually operate at higher speeds, likely at 4000 rpm. So reducing this high rpm to the required lower rpm for the operation of screw jack without bulky accessories or power loss can be challenging.  .It can be done In any type of jack cylindrical screw jack, bottle type screw jack and scissor type screw jack. In our project we use scissor screw jack which is applicable for operation.
