Packing & Delivery

As the core transmission component of NOV (National Oilwell Varco) top drive systems, NOV Top Drive Gears redefine reliability, efficiency, and longevity in global oil and gas drilling. Engineered with cutting-edge material science, precision manufacturing, and rigorous field validation, these gears are the ultimate solution for deep-well, ultra-deep-well, and geologically complex drilling environments.
Advanced Material Science:
Forged from aerospace-grade alloy steel (e.g., 20CrNiMo), our gears undergo multi-stage vacuum degassing to eliminate impurities, ensuring exceptional material purity and uniform microstructure. This delivers ultra-high tensile strength (≥1,500 MPa) and superior fracture toughness.
Thermal Treatment:
Multi-layer controlled carburizing and quenching (case depth: 1.5-2.2 mm) combined with cryogenic treatment achieve gradient hardness distribution (surface hardness HRC 58-62, core hardness HRC 32-38), balancing wear resistance and impact resilience for sudden torque shocks in downhole conditions.
Precision Machining:
Processed with 5-axis CNC grinding machines and K-profile modification technology, gear pairs achieve AGMA Class 13 (ISO 1328 Class 3) meshing accuracy. Surface roughness ≤Ra 0.4 μm minimizes edge stress concentration, reducing power loss and heat generation.
Dynamic Performance: Validated for Extreme Conditions
Torque Capacity:
Full torque range coverage from 2,000 to 50,000 N·m. FEA-optimized root fillets and tooth profiles enhance fatigue limits by 30%, supporting extreme scenarios like frequent directional reversals and high-inertia loads.
Vibration & Noise Control:
Phase-optimized meshing design and dynamic balancing (residual unbalance ≤1.0 g·mm/kg) ensure gearbox vibration ≤4.5 mm/s (ISO 10816-3) and noise levels ≤85 dB(A), enabling smooth, long-term operation.
Environmental Resilience:
PVD nano-coating (e.g., CrAlN) and high-pressure rust-inhibiting oil ensure compliance with ASTM B117 salt spray resistance (≥1,000 hours) and NACE MR0175 H2S corrosion standards. Ideal for offshore platforms, high-sulfur fields, and harsh environments.
Applications & Lifespan Assurance
Complex Drilling Scenarios:
Deep/Ultra-Deep Wells: Withstands sustained high torque and axial vibration in wells exceeding 8,000 meters.

FAQ

1-Package and transportation
According to the different characteristics of goods and customer needs, we provide a variety of packaging methods, can also be packaged according to customer requirements, packaging types include wooden boxes, iron shelves, environmental protection paper boxes, containers, etc., to ensure the safety and integrity of goods in the process of transportation:
Wooden case packaging: suitable for heavy or large volume goods, such as machinery and equipment, large parts and so on. Wooden pallet packaging has high load-bearing capacity and stability, can effectively prevent the goods from moving or damaged in the process of transportation
Paper box packaging: suitable for lightweight, fragile or regular small goods, such as electronic products, daily necessities, etc. Environmental paper box is not only low cost, but also has good environmental performance
Wood pallet packaging: The goods are fixed on the wooden pallet and reinforced with bolts or nails to ensure that the goods are closely combined with the wooden pallet. For heavy goods, additional support structures are added to prevent the goods from tilting during transportation
Container packaging: suitable for the transportation of large quantities of goods, can effectively use space, reduce transportation costs. The interior of the container can be customized according to the characteristics of the goods to ensure the safety of the goods
2-Marks and labels:
The name, specification, quantity, destination, transportation requirements and other information of the goods shall be clearly marked on the packaging surface to ensure identification and convenient operation during transportation
For special goods (such as fragile goods, dangerous goods), post a prominent warning label to remind the transport personnel to pay attention to the operation.
