PIV Drives offer a unique advantage in power transmission: the ability to infinitely adjust the output speed within a specific range without discrete gear steps. This is typically achieved using a special chain running between two pairs of conical pulleys. Adjusting the pulley spacing changes the chain’s effective engagement diameter, altering the output speed.
Essential for applications requiring fine speed adjustments.
Well-maintained units offer good power transmission efficiency.
Continuous speed variation means smooth acceleration/deceleration.
A broader range of speed adjustment than fixed-ratio gearboxes.
