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...

The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by gear (not shown) which meshes with the spur gear at D
The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the drive gear acts at a pressure angle of 20". The shaft transmits a torque to point A of TA = 340 N.m. The shaft is machined from steel with Sy= 420 MPa and Sut = 560 MPa. The fatigue...

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...
