High-Precision Pinion Gears & Shafts for Girth Gear Transmissio
As the vital power transmission component for large-scale equipment, Tenfaye’s pinion gears are engineered to drive your mills and kilns with maximum efficiency. Whether you require cast steel pinion gears or forged pinion shafts, we provide custom-manufactured solutions tailored precisely to your technical specifications and material grades .
Our drive pinions are designed to work in perfect harmony with girth gears, ensuring consistent, vibration-free operation. By focusing on tooth surface hardness and geometric precision, we help you maintain long-term stability while significantly minimizing downtime and overall maintenance costs.
Inspection: UT/MT Materials: 42CrMo4, 20MnCr5, or custom required Industries Served: Cement, Wind Power, Mining, Oil & Gas and so on Surface Treatment: Quenching and tempering heat treatment (Quenching and Tempering, Annealing, Normalizing, etc.) Selection Recommendations:ZG42CrMo+carburizing and quenching+UT full inspection is preferred(Mining/cement equipment)
Advantages
Premium Materials, Exceptional Durability Made from high-quality alloy steels (42CrMo4, 20CrMnTi) with deep carburizing & quenching (HRC58-62) for uniform hardness and 50% higher impact resistance. Optional ZG35CrMoV specialty cast steel for extreme conditions (e.g., ball mills, crushers).
Precision Machining, Perfect Meshing CNC gear grinding (DIN 3962 Class 5+) ensures tooth profile accuracy ≤0.015mm, reducing noise and vibration. Paired grinding with gear rings achieves ≥80% contact pattern and 98% transmission efficiency.
Customized Solutions, Flexible Adaptability Supports non-standard customization (Module M1-M30, diameter 200mm-3000mm), compatible with MAAG, FLENDER and other international gear ring systems. Special treatments: pre-hardening, coatings (Ni-plating/nitriding) to extend service life.
