Roda dentada da miniescavadeira Komatsu PC60-7

As the core drive component of Komatsu PC60-7 series small excavators, our mini excavator sprocket is forged with high-strength alloy steel and is specially optimized for the speed, torque and load characteristics of this model. The sprocket tooth shape meshes perfectly with the chain, which can maintain smooth operation under high load and long working hours, effectively extending the life of the travel system. Whether you are doing daily municipal construction or fine pipe trench work, this sprocket can achieve smooth start and stable propulsion, making your PC60-7 perform better.

• Preferred materials: alloy steel is used, and after multiple processes of deep quenching + tempering treatment, the surface hardness can reach HRC55 or above, with excellent internal toughness, strong impact resistance, and more than 30% improvement in wear resistance.
• High-precision tooth shape: precision CNC machining, the tolerance of tooth top, tooth root and tooth surface is controlled within ±0.02mm; the profile and roughness of each tooth surface are strictly tested to ensure smooth engagement between the chain and sprocket and lower noise.
• Surface treatment: high-temperature nitriding and phosphating dual processes are adopted to further improve the surface hardness and corrosion resistance, enhance the antioxidant capacity, and adapt to a variety of operating environments.

Processo de produção

• Forging blank: high-quality alloy steel bars are selected for isothermal forging to ensure that the internal structure is dense and uniform.
• Heat treatment: first quenching and then tempering, and then temperature tempering to eliminate internal stress; the balance of hardness and toughness makes the sprocket less likely to crack under high torque environment.
• CNC machining: precise cutting is carried out through the five-axis linkage CNC machining center, and each tooth surface is repeatedly polished to ensure the tolerance range and surface finish.
• Surface strengthening: high-temperature nitriding or phosphating treatment, combined with shot peening to eliminate residual stress and improve fatigue life.
• Quality inspection: equipped with advanced inspection equipment such as three-coordinate, hardness tester, profilometer, etc., full inspection of multiple indicators such as size, hardness, surface quality, magnetic particle flaw detection, etc.
• Dynamic balance test: The assembly test bench simulates the operation of the actual vehicle, detects vibration and temperature rise, and ensures that the products shipped meet the use requirements 100%.

Practical Guide to Installation and Maintenance

• Pre-installation inspection: Clean the sprocket mounting surface and chain guide rail to ensure that there are no foreign objects; check the tension of the chain, and it is recommended to reserve 3-5mm vertical.
• Installation steps: First manually insert the sprocket tooth groove, and then tighten the center bolt with a torque wrench according to the specified torque (recommended 350-400N·m); then start the machine and idle at low speed for 2 minutes to check the smoothness of operation.
• Daily maintenance: Add chain guide lubricant every 50 working hours to avoid dry grinding; check the wear depth of the sprocket regularly (100 hours), and replace it in time if the wear exceeds 0.5mm.
• Troubleshooting: If abnormal noise or poor meshing occurs, first check the looseness of the sprocket bolts, the tightness of the chain and the wear of the sprocket tooth surface; if necessary, remove the sprocket and use a four-coordinate measuring instrument to detect the tooth profile deviation.
