There are two bevel gears in mate (a pinion and gear) determine the maximum diametral pitch (or closest to SF) based on the bending equations and the data below: (hint: use iterative approach, meaning it make take more than one try) (Also recall that diametral pitches are standardized, find the one the closest to standardized value while satisfying the FOS) . Determine the optimal diametral pitch, P, for the pinion (use bending equations) . Design/Safety Factor (SF)2.00 Overall Factor of...

A straight-bevel gear mesh is utilized to transform the rotation
about a horizontal shaft of a motor-driven pinion into rotation of
an output gear about a vertical shaft as shown in Fig. 1. The
pressure angle f = 20°. The pinion shaft rotates at 900 rpm.
a. Both pinion and gear are Grade 2 steel through-hardened at
250 Brinell and are uncrowned. The quality number is 9 and the
desired life is 30,000 hours with a 0.999 reliability. For a...

A pair of straight bevel gears are mounted on shafts that are 90 degrees apart, and pinion transmits 10 hp at 300 rpm. The pinion has 6" outside pitch diameter, 2" face width, 20 teeth and Φ = 20˚. For a velocity ratio of 0.5, draw a free body diagram of gears showing all forces. What is torque produced about gear axis? The average pinion pitch diameter is 5.104"

A speed reducer has 20° full-depth teeth with a diametral pitch of 4 teeth/in, a face width of 3.25 inches, and with the pinion having 22 teeth and the gear having 60 teeth. The pinion is driven by a 40 HP motor rotating with a shaft speed of 1145 rpm. The pinion is designed to last for 5 years operating around the clock. The gears are manufactured using 4340 through-hardened grade 1 steel, both heat treated to 250 HB using...
