Question

1.A steel spur pinion has 16 teeth cut on the 20◦ full-depth system with a module of 8 mm and a face width of 90 mm. The pinion rotates at 150 rev/min and transmits 6 kW to the mating steel gear. What is the resulting bending stress? 2. A steel spur pinion has a module of 1 mm and 16 teeth cut on the 20◦ full-depth system and is to carry 0.15 kW at 400 rev/min. Determine a suitable face width based on an allowable bending stress of 150 MPa.
