The positive linkage among chain and gear wheel permits constant speeds even with torque fluctuations and incredibly good reproducibility of speeds. Standard variable gear products force the transmission element by applying excessive force – that is unnecessary and decreases the PIV CHAIN CONVERTORS Variable Chain Drives amount of efficiency.

Variable chain drives apply a lever system, which applies only as much strain on the slat chain as required. This outcomes in low operating temperature ranges, extended life, high power density and a great efficiency – even in the partial load range.
