Paul, I need your (group) help in helping me determine the adequacy of a
gear set. I need to know how much horsepower that the set is capable of
handing with a reasonable safety factor. This is being considered for a
psru. I hate to admit it, but it's been too long ago that I could do these
calculations.

The spur gear set is as follows:

Width:  .750"

Outside Diameter:  pinion-2.56" (26T)   driven-5.36"(52T)

Gear heigth: .200"

Material: 8620 (Rockwell 55 est) heat treated steel

Max rpm of pinion: 7,000

Thanks for the help.

Chuck H
