Climbing with CIM's: Versaplanetary Vs. P80 Vs. Multistage Planrtary/Spur Combo

[Paul Copioli]

All,

First off, the load rating for the VP is very comservative so I think using the VP in this instance is fine.

Also, since the rating is based on the ultimate stress failure of the aluminum hex, going to a single stage gearbox with a 7075 aluminum shaft (or unhardened steel shaft) won't be any better.

In any case, you should be fine with the VP direct to your output for the climber.

Wow!

That perspective is actually a little game changing. How would you feel about versas on a drivetrain?

Thanks Paul, I wasn't sure if the failure was caused by the spline or some other part of the shaft specific to the VP.
