Idler-wheel
Type of wheel / From Wikipedia, the free encyclopedia
For the Fiona Apple album, see The Idler Wheel...
An idler-wheel is a wheel which serves only to transmit rotation from one shaft to another, in applications where it is undesirable to connect them directly. For example, connecting a motor to the platter of a phonograph, or the crankshaft-to-camshaft gear train of an automobile.
