Hi,

Need help with a Gear Train described below..

1)We have a Round Plate above which there is a 88 Teeth Gear (Gear A). Both have their own drive and the ratio is 1:4. For every 1 turn of the plate, the Gear A rotates 4 times. They both rotate in the same clockwise direction.

2)On the plate is mounted a Gear B which meshes with the 88 Tooth Gear A.

We want it such that for every 1 rotation of the Plate, the Gear B rotates 18 times.

We are unable to figure out the calculation for the no. of Teeth for Gear B, and would be grateful for any help with the formula/calculation.
