Gear design based on max holding force?
Gear design based on max holding force?
(OP)
I am designing a pinion and gear to be used in a design project that I am working on. I am having an issue with the maximum torque being applied on the pinion and gear. I I was just wondering if someone knows how I would go about solving for a maximum holding force rather then operational rotational force. I know how to design the pinion and gear based on when it is moving but I don't need it to be moving for my max design load.
Anyone have any ideas?
Thanks

operating load as the maximum load and
1.4 for the max operating loads.
It does depend on your application however.

W = S b Y
where
W = Max load Pounds
S = Max allowable stress (Usually 40% UTS)
or UTS divided by the Safety Factor
for that conditional load.
b = gear face width
Y = Lewis Y factor (based on the number of teeth
of a complete 360 degree gear)
The pinion will normally be the weakest member
unless you go to a modified tooth form and then
also use a stronger material for it.
I have an excell spread sheet with the Y factor
if you need it for normal, 25 percent long, and
50 percent long addendum gears and pinions and
20 degree pressure angles.
