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.
Answer Wiki. A gearbox is a mechanical arrangement of gears (toothed wheels) done in a way to transmit power from the prime mover to the end drive. A gearbox, in its simplest form could just have one set of driver and driven gears to form a reduction drive to reduce speed and enhance torque at the end output. This type of arrangement is typically used in machinery that has an electric motor as the prime mover and requires the power to be utilised in moving heavier load than that could be done by the prime mover alone.
