An idler gear is a gear wheel that is inserted between two or more other gear wheels. The purpose of an idler gear can be two-fold.Firstly, the idler gear will change the direction of rotation of the output shaft.n idler-wheel drive is a system used to transmit the rotation of the main shaft of a motor to another rotating device, for example the platter of a record-reproducing turntable or the crankshaft-to-camshaft gear train of an automobile.
There three interlocking gears are mounted between two fixed surfaces as shown. The center gear is called a sun gear and has a angular velocity of 5 rad/s counter-clockwise. The three small gears, called planet gears, link the sun gear to the stationary other ring gear. Determine the angular velocity magnitude of the planet gears.
