A pair of spur gears with 20° full-depth involute teeth consists of a 20 teeth pinion meshing

with 41 teeth gear. The module is 3 mm while the face width is 40 mm. The material for

the pinion as well as for the gear is steel with an ultimate tensile strength of 600 N/mm2

.

The gears are heat-treated to a surface hardness of 400 BHN. The pinion rotates at 1450

r.p.m. and the surface factor for the application is 1.75. Assume the velocity factor accounts

for the dynamic load, and the factor of safety is 1.5. Determine wear strength, effective

load, torque, beam strength and rated power of gears. Assume Lewis form factor as 0.32 for

20 teetht​
