Gearbox Transmission Gear 12JS200T-1701056 Sinotruk

Product Introduction

• Structure: An integral precision-forged gear made from high-strength alloy steel, with a straight-cut external tooth profile and a keyway bore for secure mounting on the countershaft. The tooth surface is carburized and hardened, then precision ground for smooth meshing. The gear features a robust, wide-face design for increased torque capacity, and a black oxide coating for corrosion resistance.

• Performance: The high-hardness tooth surface (HRC58-62) withstands the extreme torque and impact forces of heavy-duty operation, while the straight-cut tooth profile ensures efficient power transfer. The integral forging and wide-face design provide exceptional torsion resistance, preventing deformation or fracture under full load. The precision-ground teeth minimize backlash and ensure reliable meshing with mating gears.

Core Function

1. Torque Transfer: Transmits rotational torque from the main drive gear to subsequent gears in the countershaft train, facilitating gear ratio conversion and power distribution.

2. Heavy-Duty Load Handling: The high-strength alloy steel and wide-face design safely handle the extreme torque of heavy hauling, ensuring stable performance under full load.

Precision Meshing: The precision-ground teeth ensure minimal backlash and optimal gear contact, maximizing transmission efficiency and reducing power loss.
