Abstract
Advancements in technology have led to a steady decline in the effort required to produce work, with better designs offering an effective and economical means to achieve desired outcomes with reduced effort. Power screws serve to transform rotary motion into translator y motion, as exemplified by the screw jack, where a minor horizontal force elevates or descends a substantial load. Operating akin to an inclined plane, the mechanical advantage of a screw jack is determined by the ratio of load to effort applied. Adjustment of the jack's height is facilitated by turning a lead screw, achievable either manually or through integration of an electric motor. The whole components is designed on a base plate of relatively good resistance to deformity and act as a support to weight balancing during the operation of the motor
This project analyzes the fabrication of a motorized screw jack by incorporating an electric motor in the screw in order to make load lifting easier. In this fabrication design, the power screw is rotated by connecting motor through universal joint and gear axle to power the screw jack plugged to the automobile 12 V battery source to generate power for the prime mover (motor), which transmits its rotating speed to the power screw to be rotated with required speed reduction and increased torque to drive the power screw. The significance of this project to design a car jack in form of motor operating condition in order to make the operation easier, safer and more reliable in order to reduce health risks especially back ache problems associated with doing work in a bent or squatting position for a long period of time. The motorized screw jack is easy to use by women or whoever had problem with the vehicle tyres along the road. It will also save time and requires less human energy to operate. Based on results, the project provide a motorized jack able to effectively lift a load of 750kg to 1000kg and also provide a safe usage during maintenance of vehicle.
