A gear set consists of a full depth 20-tooth pinion driving a 40- tooth pinion. The module of the set is 2.25mm/tooth and pinion is running with 1750 rpm and transmit 25 KW. If the pressure angle used is 20° and the center distance was incorrectly made 3mm in larger, compute the contact force between teeth.
A similar pair of helical gears , also on parallel axes, are to have involute teeth, of 20o normal pressure angle, and 3 mm normal module. The wheels are to have 26 and 34 teeth, and to work with a centre distance of 146 mm. Calculate the transverse pressure angle in degrees.
A simple gear train of 30 and 50 teeth for pinion and gear wheel respectively, is used to drive an electric wheelchair at a velocity that is double the maximum velocity of slip. The pinion has an equal addendum as the gear wheel, a module of 3 mm, and a pressure angle of 14.5°. The wheelchair has a maximum velocity of 5 m/s when its pinion rotates at 800 r.p.m. Calculate: 1.5. The addendum of the gears in mm. 1.6. The contact ratio.

A handle H drives a pinion A, which drives a drum E through gear wheels B,C and D as shown in Fig. 34.10. P4 H 400 mm A B D E W 200 mm The length of handle is 400 mm, and diameter of the drum is 200 mm. The wheel A has 20 teeth, which gears with wheel B of 80 teeth. The wheel C has 20 teeth which gears with wheel D of 100 teeth. Swill Find the load (W) that can be raised by the drum, if an effort of 10 N is applied at the end of the handle. Take efficiency of the system as 60%.

Two cqual involute gear wheels of 40 teeth each, 3 mm module and 20° pressures angleare in mesh. Determine the minimum addendum if 2 pairs of teeth are always in mesh.The gear wheels rotate at 750 r.p.m. and transmit 4.6 kW. Find the normal force at eachpair assuming equal direction of load between the pairs. Neglect friction.
