The PolyVee belt driven roller and RollerDrive from Interroll (Wilmington, NC) provides reliable torque transmission up to 300 percent higher than traditional O-rings. Unlike other multi-rib belts, the PolyVee belt features a flexible core that allows it to be applied without any tensioning device. In addition, the PolyVee belt accepts center-to-center distance tolerances, without impairing performance, and quickly and accurately controls the starting and stopping of boxes on a conveyor.
The high torque PolyVee multi-rib belt has a new hub and belts with up to four ribs, minimizing belt slippage and providing superior torque transmission and long life cycle. It is suited for most conveying applications including roller curves, 24VDC pallet conveyors, long transport zones, and high speed applications.
