The PIV CHAIN CONVERTORS Variable Chain Drives positive linkage between chain and gear wheel permits constant speeds even with torque fluctuations and very good reproducibility of speeds. Standard variable gear devices force the transmission element through the use of excessive force – this is unnecessary and reduces the degree of efficiency.

Variable chain drives apply a lever system, which applies only as much strain on the slat chain as necessary. This outcomes in low operating temperatures, long life, high power density and a great efficiency – also in the partial load range.
