7) [30 pts] Factor of Safety for Contact Stress 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 3 kW to the mating steel gear. This pinion is to mesh with a steel gear with a gear ratio of 4:1. The Brinell hardness of the teeth is 200, and the tangential load transmitted by the...

There are two spur gears in mate (a pinion and gear) determine the minimum face width based on the bending equations and the data below: (hint: use iterative approach) . Determine the face-width for the pinion (use bending equations) * Design/Safety Factor (SF) 2 · NP (teeth) = 20 Pressure angle (degrees) = 20 · n (rpms) = 1200 H (hp) 100 Ng (teeth) = 60 .

QIII) A 15-tooth, precision-made spur pinion is to drive a 25-tooth gear. A pitch of 6 teeth/in has been selected with a 2.25 in face width. Also, the teeth are to be 25 full depth, with a ddendum of 1.35/ pa for a pinion speed of 1150 rpm, and 10 hp is to transmitted under steady load conditions. The material selected for both gears is a through-hardened steel of a hardness of 302 Bhn . Determined the actors of...

I. The countershaft shown in the Fig Q1 has two spur gears mounted on it with teeth cut wi a 20 pressure angle. The shaft (grooved) is to be made of cold-drawn AISI 1040 steel havin Sut 779 MPa and S,-593 MPa, an elongation of 19% and HB-262. You are asked to size the shaft for safe operation according to DE-Elliptic criterion by using a factor of safety of 2.5 and a reliability of 99 percent. The stress-concentration factors for...
