At Whipple Superchargers Systems ....

We offer a wider variety in sizes of Poly V Belts than any other manufacturer, and all of them are covered by our guarantee. Poly V Belts are particularly good for high speed and/or high ratio applications which conventional belts are unable to handle. The smooth, vibration free performance and excellent reverse bend characteristics of this belt enable the design of single belt, compact drive systems. It is available in two industrial standard cross sections with superior oil and heat resistant qualities.

The Poly V Belt is gaining wide acceptance in the automotive field due to the advantages it exhibits over convention V-belts. Small section Poly V Belts (H and J sections) have been used in the appliance and business machine industry for many years. Recently, due to the need for smaller pulley diameters and increased performance, Poly V Belts have been selected for use on many applications. These applications range from the single multi-rib accessory drive concept (SMAC) for passenger cars to water pump, alternator, and air conditioning drives on heavy trucks. In addition, some fan drives on construction equipment are being placed in production.

The demand that smaller pulley diameters and increased performance have placed upon belts has brought about the utilization of the "K" and "L" section Poly V Belts. The "K" and "L" section Poly V Belts have been found to be correctly dimensioned to allow satisfactory application of the majority of automotive accessory drive systems. Poly V Belt sections which are designated by the letter "K" and "L" are easily identifiable by measuring the distance between the adjacent ribs within a belt. The "K" section belt has a smaller rib than the "L" belt and the overall thickness of the "K" is less than the "L". Examples below are for reference only. Dimensions and rib profiles can and will be changed to improve belt performance and to alleviate problems which may occur on specific applications. Consult our technical department before using these dimensions and profiles on belt specifications. Belt dimensioning is typically deferred to the belt manufacturer, at least through the development stage. After development of a satisfactory Poly V drive system, non-classified belt dimensions and material specifications will be supplied on request.

Poly V belts can be manufactured in a variety of lengths, number of ribs and material specifications. The capability of Whipple to supply Poly V belts using several different processes enables the rubber compounder and engineer total freedom in the selection of materials to obtain maximum belt performance on each individual application. Belt lengths between 20 in. (500mm) and 120 in.
(3050mm) are easily manufactured, while belt lengths outside this range are available as special production orders. Poly V belts are produced in sleeve form so that the number of ribs required by the customer for an individual belt can be slit or cut from the sleeve. This versatility allows Whipple to supply several different belt widths (number of ribs) of the same length from the same tooling.
