Description

1. The ring gear part is made of standard 45# alloy steel and high-frequency quenching process. The hardness of the tooth part can reach 48-58HRC, which makes the product more heat-resistant, wear-resistant and durable.

2. The flywheel ring gear is designed to have a larger diameter than the pinion gear to provide sufficient contact area for consistent engagement. The gear reduction ratio is important for generating sufficient torque to overcome the engine's compression and initiate rotation.

3. The inspection adopts 3-D Measuring/Metallurgical Micro-test/Hardness test/Tension test and other equipment to ensure that there will be no defective products in the factory.

4. The flywheel ring gear is designed to handle the high torque requirements of engine starting without compromising its integrity. The ring gear's tooth count and size are optimized to provide sufficient contact area for reliable torque transmission.

Principle

When starting the car, the gear on the starter motor meshes with the ring gear on the starter flywheel and drives the flywheel to rotate. Because the flywheel is installed on the engine shaft, it drives the engine to rotate and the car starts.
