The positive linkage among chain and gear wheel permits constant speeds even with torque fluctuations and incredibly good reproducibility of speeds. Standard variable gear systems force the transmission component through the use of excessive force – this is unnecessary and reduces the amount of efficiency.

Adjustable chain drives apply a lever mechanism, which applies only as much PIV CHAIN CONVERTORS Variable Chain Drives pressure on the slat chain as necessary. This results in low operating temperatures, extended life, high power density and a great efficiency – actually in the partial load range.
