Gear Train Question

VEX V5 General Discussion Technical Discussion
#1

Which would resullt in more output power?

a) Two motors attached to one gear train
b) Two seperate gear trains with one motor attached to each combined through an axle?

The difference between a) and b) is that a) has one gear train and b) has two. Same number of motors, same gear ratio.

We are observing that two separate gear trains noticibly outperforms one gear train but can’t explain why. Anyone?

#2

Theoretically with no friction both would perform the same, but in most cases the singular gear train will perform better because of reduced friction. I can’t tell why one performs the other without a specific use case, but if you are driving an arm, power on both sides is generally better than power on one side.

I did some real-world testing this summer on a similar issue. See this thread.
