Product Description
The heart of the PIV Gearboxes is the all metal slatted chain and the grooved wheel faces. To engage the grooves in the wheel faces, the chains slats travel laterally. Therefore the chain cannot slip. The pitch diameter of both pairs of wheel faces is controlled to an infinite number of positions by the pivoting control levers and the control screw. PIV Gearboxes have a positive transmission of power and outstanding stability of speed with the simplicity of design.
