PDC Model
In belt-driven power transmission systems, variable-pitch pulleys are mounted on both the drive shaft and the driven shaft. By forcibly changing the pitch on the drive side and causing the driven side to follow, the transmission ratio can be adjusted without changing the distance between the drive and driven shafts.This is a simple unit that combines a PDS model as the speed-changing mechanism with a motor and an output shaft mounted on a base.
