What is Minimum Spur Gear Thickness Away From Tooth Area

What is Minimum Spur Gear Thickness Away From Tooth Area

What is Minimum Spur Gear Thickness Away From Tooth Area

(OP)
How can I calculate the minimum spur gear thickness in the area away from the teeth? This gear is loaded on center with the gear. I would like to thin down the gear leaving a thicker web for teeth.

Dp=20
Teeth number = 19/102 (.95/5.1" dia.)
Possibly 1055 heat treated material
.8 hp @ 7000 rpm., pinion drives gear
Life - 250 hours

I can run an FEA static or buckling analysis if this helps.

I should have posted that the pinion and gear face widths would be .34"

RE: What is Minimum Spur Gear Thickness Away From Tooth Area

At 1304 rpm output speed I would not worry so much with thinning the web but with balancing the whole setup, but if you want to lighten the gear I would go the way of cutting holes instead of thinning it to less than 0.25"

You could get probably 6 holes 3/4" max diameter, 8 maybe will get you minimun weight but a little stress analisis would be good but with 6 you are on the safe side.
