H3SH H3HH H3DH13 Hard Toothed Gearbox for Steel Mills

Core Performance Advantages High Transmission Efficiency The use of hard-faced helical gear design results in a high degree of gear meshing overlap and low friction loss. Single-stage transmission efficiency can typically reach over 98%, while two-stage transmission efficiency is around 95% to 97%. High efficiency means less energy waste, leading to significant savings on electricity costs over long-term operation. High Load Capacity and Torque Gears are made of high-strength alloy steel and undergo precision heat treatment processes such as carburizing and quenching. This gives them high tooth surface hardness (e.g., HRC 58-62) and a tough core, enabling them to withstand high loads and impact forces. The housing is typically made of high-strength cast iron, featuring a robust structure and sufficient rigidity. This ensures the alignment precision of the gear shafts remains unchanged under heavy loads, further guaranteeing load-bearing capacity. Smooth Operation, Low Noise and Vibration The meshing of helical gears is progressive. Compared to spur gears, the engagement process is more continuous and smoother. This significantly reduces operational impact and vibration, resulting in lower noise levels and an improved working environment. Long Service Life The combination of high-hardness gears, high-quality bearings, rational structural design, and precision manufacturing processes ensures the gearbox has an exceptionally long design life. With correct selection and maintenance, it can typically operate continuously for several years or even over a decade.
