In the industrial and commercial sectors, one in three electric motors use belt drives. However, some customers fail to take advantage of the potential energy cost savings of certain industrial belts, which are readily available and cost -efficient. While pulleys control the speed of the equipment, industrial belts are designed to position the motor relative to the load. High efficiency and low maintenance are key components to top performing belt transmission systems.
Heavy loads often require joined or multiple belts. At the time of installation, V-belts have 95% to 98% peak efficiency. Pulley size, driven torque, under or over-belting, and V-belt design and construction impact efficiency. V-belts have a nominal efficiency of 93%, a reduction of 5%, over time if slippage occurs because the belt is not periodically re-tensioned.
Cogged belts have slots that run perpendicular to the belt’s length, helping to reduce the bending resistance of the belt. While using the same pulleys as v-belts, cogged belts manage to run cooler, last longer, and increase efficiency by 2% from standard v-belts.
Synchronous belts, often referred to as timing belts, boast a 98% efficiency, which is maintained over a wide load range. These toothed belts require the installation of mating tooth-drive sprockets. Synchronous belts require less maintenance and re-tensioning, operate in wet and oily environments and run slip-free. While synchronous belts are the most efficient, they can be noisy, transfer vibrations, and are unsuitable for shock loads. In such applications, cogged belts are the better choice.
1.Gather your own data, including operating hours and productivity, of your belt-driven equipment. Determine for yourself if replacing existing v-belts with cogged or synchronous belts and sprockets is a cost-efficient solution for your application.
2.Consider cogged or synchronous belts when installing new equipment. The price premium is minimal compared to the inevitable future costs of conventional pulleys.
