The positive linkage among chain and gear wheel permits constant speeds despite having torque fluctuations and incredibly good reproducibility of speeds. Standard variable gear products force the transmission element by applying excessive force – this is unnecessary and decreases the amount of efficiency.

Adjustable chain drives apply a lever system, which applies only as much PIV CHAIN CONVERTORS Variable Chain Drives strain on the slat chain as necessary. This results in low operating temperature ranges, extended life, high power density and an excellent efficiency – also in the partial load range.
