• Specification

• Function

1.Transferring torque: The starting motor gear ring, also known as the flywheel ring gear, is mounted on the flywheel connected to the engine's crankshaft. When the starting motor operates, its pinion gear meshes with the teeth of the starting motor gear ring. The torque generated by the starting motor is transferred to the engine's crankshaft through the gear ring, enabling the crankshaft to rotate and initiating the engine's combustion process.

2.Maintaining rotational momentum: In addition to starting the engine, the flywheel gear ring also helps maintain the engine's rotational momentum. During the engine's operation, the flywheel stores rotational energy, and the gear ring, as an integral part of the flywheel, contributes to smoothing out the engine's power delivery. It reduces vibrations and provides a more consistent rotational motion, which is beneficial for the stable operation of the engine.
