Product Description
Product Introduction
-
Structure: Integrated one-piece design, with the input shaft and 1st gear forged from a single billet of high-strength 20CrMnTi alloy steel. The gear teeth are carburized, quenched, and precision-ground, achieving a surface hardness of HRC 58–62and a core hardness of HRC 33–45. The shaft features a splined end for clutch connection and precision-machined journal surfaces for bearing support.
-
Key Specifications:
-
Material: 20CrMnTi carburized steel (integral forging)
-
Surface treatment: Carburizing + quenching + gear grinding
-
Spline: External involute spline (clutch connection)
-
Gear teeth: Precision-ground involute profile
-
Operating temperature: -40°C to +150°C
-
Performance: The integral forging ensures maximum torsional rigidity, eliminating the risk of gear separation from the shaft. The hardened gear surface resists pitting and wear, while the precision-ground teeth ensure smooth, quiet meshing with the countershaft 1st gear.
-
Core Function
-
Power Input: Transmits engine torque from the clutch directly into the transmission.
-
Torque Multiplication: The integrated 1st gear provides the highest torque ratio for heavy-load starting and low-speed climbing.
-
Rigid Power Transfer: The one-piece design eliminates backlash and ensures zero-loss torque transmission.
