An idler-wheel is wheel which serves only to transmit rotation from one shaft to another, in applications where it is undesirable for connecting them directly. For instance, connecting a engine to the platter of a phonograph , or the crankshaft-to-camshaft gear train of an automobile.
Because it does no work itself, it is called an “idler”.
In a belt drive system, idlers are often used to alter the road of the belt, in which a direct path would be impractical.
Idler pulleys are also often used to press against the trunk of a pulley to be able to raise the wrap angle (and thus contact area) of a belt against the operating pulleys, increasing the force-transfer capacity.
Belt drive systems commonly incorporate one movable pulley which is spring- or gravity-loaded to do something as a belt tensioner to support stretching of the belt because of temperature or wear. An idler wheel is generally used for 
Idlers that don’t quit. Belt tension that won’t slip. That’s the Ever-power assure with our heavy-duty, wear-resistant idler pulleys and sprockets, designed to reduce put on, friction, and vibration on your own drive system belts, eventually extending your belt services life.
