Product Description
Product Introduction
This precision-forged gear is a core component of the transmission’s main shaft gear set, engineered to handle high torque loads and provide smooth, reliable engagement between first and second gears.
-
Structure & Material:
-
Material: High-strength alloy steel, precision-forged and heat-treated to achieve a hardened tooth surface and a tough, impact-resistant core.
-
Design: A dual-profile helical gear with one set of teeth for 1st gear and a second set for 2nd gear, designed to mesh with the corresponding countershaft gears.
-
Finish: The gear teeth are precision-ground for optimal meshing, reduced noise, and minimal wear.
-
Performance:Transmits high torque loads during low-speed driving and gear changes, ensuring smooth power delivery and precise engagement.
-
-
The helical tooth design reduces noise, vibration, and harshness (NVH) while distributing load evenly across the gear teeth for increased durability.
-
Durability: The hardened steel construction and optimized tooth geometry withstand the high stress and impact of frequent gear changes and heavy-duty operation, ensuring long service life.
-
Core Function
-
Torque Transmission: Transmits engine torque from the countershaft to the main shaft in both 1st and 2nd gear ratios.
-
Gear Engagement: Slides along the main shaft to engage either 1st or 2nd gear, enabling smooth gear changes.
-
Noise Reduction: The helical tooth design minimizes gear noise and vibration, improving driving comfort.
