Can the ring gear be used in a car starting system?

The ring gear is a critical component in the car starting system, commonly referred to as the "flywheel ring gear" or "starting ring gear". It plays an important role in starting the engine. The following are the specific applications and functions of ring gears in car starting systems:
1. As the meshing component of the startup system
The flywheel ring gear is usually installed on the flywheel of the engine to mesh with the small gear of the starter motor;
When the starter is running, the small gear of the starter extends through the electromagnetic control device, meshes with the flywheel ring gear, rotates the flywheel, and starts the engine.
2. Provide power transmission and torque amplification
During the start-up process, the meshing between the ring gear and the starter gear transmits power. When the flywheel ring gear rotates, it drives the engine to rotate, helping the engine complete its initial start-up;
The tooth profile design of the ring gear can withstand large loads from the starter motor, converting the high speed and small torque generated by the electric starter motor into low-speed and high torque output to overcome the high starting resistance of the engine when starting.
3. Reduce the impact and wear during startup
The design of the gear ring (usually through the use of wear-resistant materials and heat treatment techniques) ensures the smoothness of the meshing process and reduces the impact force generated during start-up;
The flywheel ring gear usually has high hardness and strength to avoid excessive wear caused by frequent meshing, thereby extending the service life of the ring gear and starter gear.
4. Ensure the reliability of high-frequency start stop operation
In the start stop system of the engine, the flywheel ring gear needs to undergo repeated meshing and separation, and the design of the ring gear needs to ensure the reliability of long-term high-frequency start stop;
The material of the gear ring (such as alloy steel or special steel) and surface treatment processes (such as quenching, hard coating, etc.) help to improve the wear resistance and impact resistance of the gear ring.
