The cylindrical gear of Dongyang heavy truck is an important part of the mechanical structure. Since the car came out, the gear has occupied an important position in its structure. Gear technology: Dongyang heavy truck cylindrical gear requirements are very high, gear teeth should have a higher ability to break, the tooth surface should have a strong pitting resistance, wear resistance and higher anti-gluing ability, that is, the requirements: Dongyang heavy truck cylindrical gear tooth surface hard, core tough. Therefore, Dongyang heavy truck cylindrical gear processing process is also very complex, generally have the following processes: forging normalizing mechanical processing local copper plating carburizing quenching low temperature tempering shot peening teeth (fine grinding), so processed out of Dongyang heavy truck cylindrical gear, both has enough strength and toughness, tooth surface and has high hardness and wear resistance.
