A commercially housed gear driver consists of a 20° spur gear
with 16 teeth and controls a 48-tooth ring gear. The pinion speed
is 300 rpm, the face width is 2 inches and the diametral pitch is 6
teeth/inch. The gears are grade 1 steel, fully hardened to 200
Brinell, with number 6 quality standards, uncrowned and made to
number 6, unbored and made to be rigidly and accurately
mounted.
Assume a pinion life of 108 cycles and a reliability of 0.90.
Determine the AGMA bending and contact stresses and the
corresponding safety factors if power is to be transmitted.
if a power of 5 hp is to be transmitted.
