Pneumatic Bearing Puller Machine

A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts. They are mostly associated with the rotating members. The wide user of bearings is the Automobile industry where the bearings are used in the engines, transmission system, and steeringsystem and in other areas where rotation involves. The mounting and unmounting of a bearing from an engine or from a shaft is a tedious job as the 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 pneumaticsystems 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.

This journal deals with the installation and removal of bearings with the hydraulic effort and how the hydraulic cylinders and control valves are installed for the effective mounting and unmounting of bearings.

Pneumatic cylinder(s) (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Pneumatic cylinder

A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges.

3.3 HAND LEVERVALVE

Hand lever valves for directional control are one of the most fundamental parts in hydraulic machinery as well as pneumatic machinery. They allow fluid flow into different paths from one or moresources.

3.5 CONNECTORS

Air hose connectors, as the name implies, are small gadgets or devices that allow a flexible tube or pipe to be linked with compressors on one end of the tube, as well as with other devices that facilitate the delivery of compressed gas on its oppositeend. Air Hose Connectors

A bearing puller is a tool used to remove bearing sets from a rotating machine shaft or from a blind bearing hole.

Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for manyapplications.

3.10 BOLTS ANDNUTS

A bolt is a form of threaded fastener with an external male thread. A nut is a type of fastener with a threaded hole. Nuts are almost alwaysused in conjunction with a mating bolt to fastenmultiple parts together.

3.11 VICE

A vice is a mechanical apparatus used to secure an object to allow work to be performed on it. Vices have two parallel jaws, one fixed and the other movable, threaded in and out by a screw and lever.

Isometric View File Component The project hardware functions satisfactorily as per the design. The project work was developed after conducting a number of experiments before finalizing the design work which reduced the bottle necks. Using this project, the bearings can be easily mounted and uncounted with less efforts and also in safer manner. As the initial cost and maintenance cost are low, it is useful in workshops and small scale industries. are low, it is useful in workshops and small scaleindustries.
