Design and Fabrication of Pneumatic Bearing Puller Project


Abstract: Nowadays pneumatic system plays an important role in almost all application. As in automobile industries, small service center, aircraft industries where precision is required. Traditional method of bearing removal or installation is hammering which causes several problems. The unsafe and excessive hammering cause damage of bearing surface or sometimes chance to failures. The modification is made which makes easy removal and installation of bearing. Pneumatic bearing puller and pusher which is based on Pascal law “pressure distribution in an enclosed cylinder is uniform in all direction” is developed to solve the conventional hammering process. This project is mainly focused to reduce the human effort and the wear and tear that occurs while mounting and unmounting a bearing. So, this can implemented in automobile industries, workshops, and in other factories where bearings may be a part of the product.conventional method is hammering which involves lot of human effort and there are many chances for bearings to get damaged. So to reduce these ambiguities the solution is brought with the help of pneumatic systems where air pressure is utilised to mount and unmount the bearings. This is achieved by using a pneumatic cylinder which is operated using a compressor and the plunger of the pneumatic cylinder is fitted with the corresponding pusher or puller depending upon the needs.The pneumatic cylinders are available in different ranges of operating pressures, so depending upon the load requirements the pneumatic cylinder can be chosen. The setup requires only less operating space and it is also portable, so that it can be connected with compressors which may be at different spots in an industry. This also consumes less time thereby increasing the productivity. The control of the Pneumatic cylinder is a hand lever valve which is used to determine forward or return stroke of the plunger fitted with the pusher or puller. The frame is so designed to house an engine casing and provisions for fixing vice to hold shafts. The pneumatic cylinder is fitted vertically by providing two columns in the either sides and a horizontal plate at the top.After connecting the arrangements properly, switch on the compressor which act as the input for the pneumatic cylinder. The compressed air from the compressor is then send to the hand lever valve through the filter regulator lubricator [FRL]. FRL removes the dust particles from the compressed air and helps us to set the required amount of air pressure needed for the operation. Then turn on the FRL and set the required air pressure. Now the air comes to the hand lever valve. Hand lever valve act as the direction control of the air. When the hand lever valve is moved forward, the pressure of air goes to the bottom port of the cylinder and this makes the piston rod of the cylinder to move in the forward direction .when the hand lever valve is moved towards reverse, the pressure of air goes to the top port of the cylinder and thus makes the piston rod of the cylinder to move in the reverse direction. On the both ports of the cylinder the flow control valve is fixed which helps us to control the movement of the piston rod.--DESIGN AND ANALYSIS OF PNEUMATIC BEARING PUSHER AND PULLER
