A starter ring gear, sometimes called a starter ring or ring gear, is a medium carbon steel ring with teeth that is fitted on the periphery of a flexplate or flywheel of an internal combustion engine, mostly for automotive applications.
The teeth of the starter ring are driven by the smaller gear (the pinion) of the starter motor. The primary function of the starter ring is to transfer torque from the starter motor pinion to the flywheel or flexplate to rotate the engine to begin the cycle.
The starter ring gear is most commonly made by forming a length of square or rectangular steel bar into a circle and welding the ends together. There then follow various heat-treatmentlike normalising and tempering and machining operations, including the machining of the teeth and finally a heat-treatment operation. The teeth of the starter ring need to be hardened in order to increase their strength and resist wear. The normal hardness at pitch circle diameter is ****5 HRC. The hardness at the root of the teeth is about *0 HRC and at 2 mm below root the hardness is *5 Hrc max. The body of the ring is generally left untreated.
Engines with manual transmission usually have a heavy flywheel, typically 5 to *0 kg of cast iron, with the starter ring gear shrunk onto the outside. This is done by heating the ring to around **0 °C to expand the ring which is then placed onto the flywheel, hold the ring gear with hydraulic pressure of 5 kg/cm2 for 1 min and allowed to cool the ring gear.The starter ring is thereby firmly attached to the flywheel.
