Gear motor is medium operational
power motor with moderately efficient and simple in design. The main components
of a gear motor are idler shaft, output shaft, an inlet for putting high
pressure oil, outlet for the passage of low pressure oil, casing and gear. Two
meshing spur gears with shafts are carefully fixed on the bearing located in
the closed housing. Inlet and outlet ports for the passage of oil are designed
in the housing. One gear is mounted on the output shaft projecting out of the
casing and the other kept idle. Gear moves in opposite direction by the
influence of high pressure oil. Efficiency of gear motor is independent of
pressure, speed and torque. Gear motors are used in medium speed and low torque
applications.
