Pulley alignment is important to flat belts. Belt tracking is improved by crowning at least one pulley, usually the larger one. Flat belts are forgiving of misalignment; however, proper alignment improves belt life.
Different flat belt surface patterns serve various transmission requirements. In high-horsepower applications and outdoor installations, longitudinal grooves in the belt surface reduce the air cushion flat belts generate. The air cushion reduces friction between the pulley and belt. The grooves nearly eliminate the effects of dirt, dust, oil, and grease and help reduce the noise level.
Flat belts operate most efficiently on drives with speeds above 3000 fpm. Continuous, smooth-running applications are preferred. Speed ratios usually should not exceed 6:1. At higher ratios, longer center distances or idlers placed on the slack side of the belt create more wrap around the smaller pulley to transmit the required load.
