Dual versaplanteary's with different reductions question

[marccenter]

Dear CD,

On our intake mechanism this year we have found dual purposes. One function operates best at a 10:1 reduction for increased speed and the other at more like 100:1 for increased torque. Tomorrow we will be adding two separate motors and it appears there may be two options available.

1) Make both versaplanetary gear reductions something in the middle, right now 40:1, and compromise a bit on both functions. This is the planned route.

2) What would happen if we have one versaplantary gear reduction be 10:1 and the other 100:1? They are chain driven to the same shaft so I was wondering what issues would I have if I only enabled the 10:1 motor/gearbox when speed is desired and only enabled the 100:1 motor/gearbox when torque is desired? Obviously the speed would decrease somewhat at the 10:1 condition because the other motor/gearbox is along for the ride and similarly the torque would be decreased from the 100:1 motor/gearbox. Would the negative tradeoffs be worse than option 1?

Best regards,
