Hi there,

I want to create a gear train assembly having a gear ratio of 130 and the input and output direction to be the same. So to do this, I made an assembly of gears like this:

A B C D E F G

Where A, C, E and G are input gears with A having a rotary motor attached to it, and B, D, F are the driving gears. I set the number of teeth of each gear so that the gear ratio (B*D*F)/(A*C*E*G) = 130. However, when I check the plot results of the input and output gear, the velocity is exactly the same. Why is this and how can I fix it? I believe if the ratio is 130:1, I should be getting 19/130 (0.146) RPM at the output (since my input is 19 RPM).

Help would be appreciated. I have attached my assembly.
