Hypoid gearing question
(OP)
Can a hypoid gear reducer, 25:1 ratio, be back driven through the output shaft?

Unless you're counting on it not happening; then it will.

Worm gears can be back driven only if the tangent of the worm angle is above or below (I cannot rmemeber which) the coeffiecient of friction. In the late 1950's early 1960's Puegeot Automobiles had a worm drive differential.

I have seen a Helicon set at 25:1, and they look similar to hypoids, except that the pitch surface of the pinion is a right circular cylinder and the pitch surface of the crownwheel is a planar ring. Like a hypoid, the axes are nonintersecting.

RE: Hypoid gearing question
This is an inherited project that may have gone too far and I am just trying to salvage the "to date" cost. I don't have a good feeling about the system; especially, since starting this thread my study has led to the fact that not all hypoid sets are even bidirectional. Well, if it can't be driven in both directions from the input shaft, what are the chances of being driven in either direction from the output side?
If there is any interest by you to know the outcome of the research give me a "yea" and I will be happy to post it. Due to my current work load that won't happen for at least two weeks.
Thanks again, I really appreciate this forum.

It's beginning to sound like a project that's potentially overflowing with 'lessons learned' ... that will not be learned.

It may be easiest to install a "backrun brake" which is basically an overrunning clutch on your input shaft, either before or after it meshes with the driven wheel. These are often used even when it doesn't seem possible that it will be needed. As others have indicated, almost any gearset can be made to run, or at least creep, backwards.
