quick lift jake with gear project pdf
Our project is to reduce the difficulty present in the lifting of four wheelers. That means reducing the human effect to lifting the vehicle.
COMPONENTS:
Jack
Base
Connecting rod
Jack connector
Slider
Motor
Battery
CONSTRUCTION:
We using a motor to automate the project. This motor is connected to the slider so that it will rotates. And this slider is connect ( slides) to the connecting rod. And the connecting rod is connected to the jack. So that the rotating movement of motor is converted to the up and down movement of connecting rod. That means we are reversing the slider crank mechanism. Due to the up and down movement of the connecting rod creates the jack to lift. The continous running of motor creates jack to lifting up. The jack is a Hydraullic system, so that it will raised smoothly without any impact forces. These parts are fitted in a top of a base. This base is absorbs all impact forces without any damages.
HYDRAULIC SYSTEM:
In the development of the submarine from pre-war classes, many changes and improvements have occurred. One of the outstanding differences is the large variety of submarine devices which are now operated by hydraulic power.
In early classes, there was no hydraulic systems, and power requirements were met by means of air or electricity. Along with constantly improving submarine design has gone a constant extension and diversification of the use of hydraulic power.
WIPER MOTOR:
The mechanism behind wipers is the windshield wiper motor, which provides the power the wiper need. A linkage converts the rotational output of the windshield wiper motor into the back and fourth motion of the wipers.
A worm gear controls the force that the windshield wiper motor delivers to the drive arm by slowing down the speed if the electric motor by 50 times while multiplying the torque by 50 times.
