4. A single stage helical gear reducer is to receive power from a 1440 r.p.m., 25 kW induction motor. The
gear tooth profile is involute full depth with 20° normal pressure angle. The helix angle is 23°,
number of teeth on pinion is 20 and the gear ratio is 3. Both the gears are made of steel with allowable
beam stress of 90 MPa and hardness 250 B.H.N.
