TO THE PROJECT SEMINAR ON AUTOMATIC SCREW JACK WELCOME SUBMITTED BY GROUP D
A screw jack is a device by which the heavy load can be lifted with the apply of the very little force. Car jack is a type of the screw jack which is generally used to lift the car when its wheel is need to be mented or to be repaired.
WORKING OF THE CAR JACK The car jack basically work on the conservation of the motion. The car jack converts the rotary motion into the translatory motion. The car jack is operated by turning the leadscrew of the jack by some lever mechanism. The jacks compressive force is obtained through the tensile force applied by its lead screw. Acme or trapezoidal thread is generally used in the leadscrew as this is very strong and can resists the large load imposed on it .
WORKING OF THE AUTOMATIC CAR JACK
The automatic car jack basically work on the conservation of the motion .The automatic car jack converts the rotary motion into the translatory motion . The auto. car jack is operated by turning the leadscrew with the motor and belt and pulley mechanism which eliminates the requirement of the human labour to rotate the leadscrew. The motor is driven by the 12V battery which is generally the battery of car itself.
ADVANTAGES OF THE AUTOMATIC CAR JACK OVER THE CONVENTIONAL CAR JACK
No physical labour or man power is required to lift the car.
Easy to handle.
Cheap ( 6,000 approx.).
