Product Description
Product Introduction
-
Structure: Precision-forged from high-strength 20CrMnTi alloy steel, featuring an external involute gear tooth profile and internal splines for a press-fit connection to the input shaft. The gear is carburized, quenched, and precision-ground, achieving a surface hardness of HRC 58–62and a core hardness of HRC 33–45 for optimal wear resistance and impact toughness.
-
Key Specifications:
-
Material: 20CrMnTi carburized steel
-
Surface treatment: Carburizing + quenching + gear grinding
-
Fit type: Press-fit with internal splines
-
Operating temperature: -40°C to +150°C
-
Performance: The hardened, ground tooth surface resists pitting and wear under high torque loads, while the tough core withstands shock loads during gear engagement. The precision-machined spline ensures zero backlash power transmission.
-
Core Function
-
Torque Transmission: Transmits engine torque from the input shaft to the countershaft 1st gear, providing the maximum torque multiplication ratio for heavy-load starting and low-speed climbing.
-
Power Transfer: Enables smooth meshing with the countershaft 1st gear to transfer power through the transmission.
-
Wear Resistance: The hardened tooth surface maintains performance over millions of cycles in heavy hauling and off-road conditions.
