Starter 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.
It's primary function is to transfer torque from the starter motor pinion to
the flywheel or flexplate to rotate the engine to begin the cycle.
A 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.
This ring is then machined to create flat surfaces of the required inner and
outer diameters. The gear teeth are then created using a hobbing tool,
followed by processes to chamfer, debur and clean the gear teeth.
