Four-pulley Two-speed Drive: Ideal Ratio Comparison
Compare two ideal no-slip speed ratios and their paired pitch-diameter sums. Equal diameter sums alone do not establish that the same belt fits both positions.
Three-pulley Two-speed Drive: Ideal Speed and Torque Ratios
Compare two stepped-pulley speed ratios and reciprocal lossless torque ratios. The schematic idler redirects the belt; belt fit, tension and shifting are not calculated.
