V-Belt Pulleys

This drive belt design offers low noise output at very high speeds, giving smooth running and large transmission ratios, combining the high flexibility and light weight of flat belts, with the grip and performance of V-belts.

A drive belt tensioner is a pulley mounted on a spring mechanism or adjustable pivot point that is used to keep tension on the engine belts. ... When the tensionerhas an issue, it can affect the how the belts drive the pulleys which can affect the performance and functionality of the vehicle.

A pulley is a wheel driven by a motor. A belt is looped around this wheel and around a second wheel. When the motor is turned on, the powered wheel turns the belt which turns the second wheel. This arrangement can be used to either increase power, increase speed and to change direction of motion.

A gear has a diameter and teeth that mesh directly with another gear. A pulley has a diameter and transmits motion via a belt or rope to another pulley. In both cases, the ratios of diameter determine the speed/ torque of the final gear or pulley.

The molded crown helps to center the belt and prevent rubbing against the outside flanges. This arrangement provides maximum support where it is needed--under the highly stressed center of the belt! A wide range of widths and diameters is available to suit virtually any flat belt idler requirement and several types of factory-mounted bore adapters are offered.

Our pulleys use a Taperlock bush to adapt the bore down to a standard parallel shaft with keyway. The bush is mounted to the pulley using the the Taperlock bush, as you tighten the screws the bush gets compressed into the tapered pulley and clamps the shaft and key
