Abstract :
This paper presents the development of an
improved hydraulic bearing pusher and remover that
uses electric motor for its operation. The conventional
approach to removing a bearing from its shaft requires
hammering or using more force which is a challenging
one. This method damages the bearing surface, may
render the bearing unusable and uses more human force.
The use of hydraulic system in place of this eliminates
the limitation of the conventional methods of bearing
removal. The development of an electronically powered
lever-operated hydraulic bearing puller makes bearing
removal faster, safer, require lesser human force, and
prevents damages to the bearing surface. Mild steel was
used for the fabrication because it satisfies design
requirements for strength, stiffness, and machinability.
The developed hydraulic bearing pulling machine
components includes; frame, cylinder mounting table,
hydraulic cylinder, working table/bed, hydraulic tank,
electric motor and hand lever. Several design equations
were used in the design of the machine's component
pieces. The FEA shows a maximum stress of the
structure to be 1.613MPa which is low when compared
to the yield strength of the material for the frame (Mild
Steel) and its maximum factor of safety to be 1.052
which shows that the structural beam is capable of
bearing the stress without failure. The average bearing
removing time for the developed bearing puller was
15min which makes the developed machine a more
efficient and faster means of bearing remover. The
primary goal of this project is to reduce the amount of
human labor, time required and eliminate damages
when removing and installing a bearing.
