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.
Non-intersecting and Non-parallel worm and worm gearsSpur gears:: âIf teeth of the gear wheels are parallel to the axis of wheel, the gears are called spur gears.â Spur gears are used for transmitting power between two shafts when the axis of the driving and driven shafts are parallel and co-planer. Spur gears: Wheel of gear Pinion Spur Gear.
