Hydraulic Bearing Puller

This is Mechanical project on "hydraulic bearing puller" and deals with design and fabrication of a hydraulic bearing puller, which is used for removing bearings from the shaft and the bearing cup with the help of a hydraulic.

First of all the bearing shaft is held between two fixtures. The hydraulic is passed to the direction control valve. The top fixture is moves up wards, so that the bearing is eliminated from the shaft. The shaft is kept vertically between the top fixture. The bearing shaft is kept in the top of the fixture. The remaining portion of the shaft touches the bottom fixture.

At the same time the pump is loaded to get the pressure required and the hand operated valve is manually to move the piston. The top fixture in the piston had inserted to its required position rod pushes the bearing which is placed on the shaft. When the bearing has removed to its original position, there will not be any further down ward movement. Then the valve is brought to the output position in which the air moves the piston upward and the shaft is removed.
