Multiplier Gear Ratio Help

Multiplier Gear Ratio Help

I'm trying to create a multiplier gear pair, with a ratio of 3:1. I have modelled the gears and defined them using the Gears tool in Mechanism, but whenever I try to set a gear ratio it is always set as a reduction pair i.e: Gear 2 spins 3 times slower than Gear 1. I want the opposite, for Gear 2 to spin 3 times faster than Gear 1.

I have tried setting the gear ratio by pitch circle diameter (the first gear has a radius 3 times that of the second), and also using a user defined setting. Whichever way I set D1 and D2, the second gear always spins slower than the first.

How do I force my gear pair to be a multiplier instead of a reducer?

Re: Multiplier Gear Ratio Help

I'm not an expert at mechanism, but, it seems you have the input and output gears picked wrong?  Depending on which gear is driven, it is either/or.

Good luck!

Big drive to little driven produces speed?
