Poly V - Multi Rib Belts

This belt category is basically a flat belt with a corrugated driving surface; ridges running longitudinally around the inside of the belt. The groove-to-groove pitch distance, groove angles, groove depth of these poly V belts comply with international standards. The common profiles are H, J, K, L, and M, being relatively thin, with a well-supported tensile member, these belts perform better than V-belts on drives with small diameter pulleys. They are particularly suited to serpentine pulley configurations and can drive flat pulleys from the backside of the belt as well which is important in serpentine drives. The low mass and high flexibility of Poly v/ribbed belts allow them to tolerate small diameter pulleys, reverse bending, high drive speed, and high speed ratios. Poly V/ribbed belts do not rely as much on the wedging action (as a v-belt) to transmit torque, and therefore tensions tend to run higher
Typical Applications
The “H” profile is used primarily in the white goods appliance sector as the drive belt for washing machines and tumble dryers. They are also found in many small electric hand tools and equipment like belt sanders and kitchen blenders. The “K” profile has been used almost exclusively in the automotive market as the prime driver for front-end accessory drives (FEAD). One belt, connected to the vehicle crankshaft will drive the alternator, water pump, power steering pump, A/C compressor, and other auxiliary equipment, such as air pumps or alternator/and the modern starter hybrids.

The “J”, “L”, and “M” belt profiles can be used on many industrial drives and can in some cases replace the Classical or Wedge belts.

  1. Our Multi Ribbed Belts by Pixtrans consist of multiple V-grooves. The design allows operation on small pulley diameters. Multi Ribbed Belts offer high Belt speed. Multi Ribbed Belts are designed for high power transmission ratios and offer high power output. Multi Ribbed Belts enable economic solutions even under difficult drive conditions, such as large transmission ratios, high Belt speeds, small pulley diameters and back idler pulleys.
