Applying the Aramid Joined v-belt high torque, low speed oil field pumping units

This paper discusses the successful application of Aramid fiber-reinforced Torque Team Plus Joined Vbelts to low speed; (8-20 rpm) high torque, up to (320,000 in-lb); 100% belt driven oil field pumping units. Also discussed is a comparison in operating efficiency over gear or chain units, reduced initial expense, and lower overall maintenance effort. The Aramid reinforced Joined V-belts were applied to a double reduction drive (68-142:1 ratio) eliminating gear or chain reducers. Pumping units range in size from 57,000 in-lb to 320,000 in-lb.
