Mechanical Role and Performance Function

Torque Transmission Efficiency

The 22W-15-22440 GEAR KOMATSU serves as a torque multiplier and rotational converter, transferring motion from the input shaft to the driven components within the Komatsu drivetrain. Its straight-cut teeth ensure stable contact pressure, reducing sliding friction and optimizing power efficiency in both forward and reverse movements.

Shock Load Absorption

Thanks to its hardened tooth surfaces and ductile steel core, the gear resists cracking under sudden impact or overload. The transition radius between the tooth root and face is optimized to distribute stress evenly, preventing micro-fractures and tooth pitting even after prolonged operation in high-torque cycles.

Dimensional Accuracy

Every 22W1522440 GEAR KOMATSU is machined to a tolerance of ±0.01 mm in bore concentricity and ±0.005 mm in tooth runout, ensuring smooth meshing and balanced rotation. This precision reduces noise, vibration, and wear — key indicators of long-term drivetrain health.

Manufacturing and Quality Control Process

At 3GEN Export, every 22W-15-22440 GEAR KOMATSU follows a meticulously controlled production cycle:

1. Material Preparation: Certified alloy steel billets undergo spectrographic analysis to verify chemical composition.

2. CNC Cutting: Teeth are cut using multi-axis gear hobbing machines for exact profile geometry.

3. Heat Treatment: Carburizing and quenching harden the tooth surfaces for wear resistance while preserving a tough, flexible core.

4. Grinding and Lapping: Precision grinding removes residual distortion, while lapping achieves a mirror-smooth finish on all contact surfaces.

5. Hardness and Crack Testing: Rockwell hardness and magnetic particle inspection ensure metallurgical consistency.

6. Final Dimensional Verification: Each gear is tested for pitch accuracy, backlash, and overall balance before packaging.

This combination of modern metallurgy and precision machining makes the 22W-15-22440 GEAR KOMATSU a long-lasting solution for maintenance engineers and fleet operators worldwide.
