Product Description
Product Introduction
This precision-engineered transmission gear is a vital part of the gear train, responsible for transmitting torque and establishing one of the transmission’s forward gear ratios.
Structure & Material: Made from high-strength alloy steel, it features external helical teeth for smooth meshing and internal splines for secure mounting on the transmission shaft. The surface is carburized and quenched for exceptional hardness and wear resistance.
Performance: The helical tooth design ensures smooth, quiet power transfer with reduced noise and vibration. The hardened surface resists wear from high torque loads and continuous operation.
Durability: The hardened steel construction withstands high torque, shock loads, and friction, ensuring long service life even under harsh operating conditions.
Compatibility: Direct OE replacement, fully matching the tooth profile and dimensional specifications of the HW19710 transmission’s gear train.
Core Function
Torque Transmission: Transmits rotational torque between gears in the transmission’s gear train, establishing a specific gear ratio.
Smooth Operation: The helical tooth design ensures quiet, vibration-free meshing with mating gears.
Gear Ratio Control: Contributes to the overall gear ratio range of the transmission, enabling optimal vehicle performance and fuel efficiency.
