Buy at Copyright (c) 2015, M. Oskar van Deventer. Extreme Reduction is an ultra-compact gearing system with an extreme reduction. The gear ratio is : 1, that is, over eleven million to one!!! That extreme reduction is achieved in three stages. -Stage 1: Two sets of planetary gears with a reduction of 24 : 1 and 25 : 1, respectively. -Stage 2: Two subtractions, 26×26-25×27=1 and 25×25-24×26=1, respectively. -S
