DL Model
In this offset coupling, which utilizes the crankshaft motion of the link, the power input to one end disc is transmitted to the other end disc via the link and the center disc. Because power is transmitted via the link, reaction forces are extremely low, allowing for a large eccentricity of up to ±4 mm.
