FADR Series Planetary Reducer (FADR47/FADR64/FADR90/FADR110/FADR140/FADR200): Heavy-Duty Explosion-Proof & Corrosion-Resistant Transmission Solution
I. Product Overview
Weigao FADR Series Planetary Reducers, covering full models from FADR47 to FADR200, are heavy-duty enhanced transmission devices tailored for harsh industrial environments requiring explosion protection, corrosion resistance, and stable heavy-load operation. As an upgraded special-series product in Weigao's planetary transmission lineup, this series addresses the pain points of poor environmental adaptability, weak overload capacity, and short service life of traditional reducers in petrochemical, marine, and food processing scenarios. Compliant with ATEX II 2G/2D, IECEx standards and certified by ISO 9001 quality management system and IP67 protection level, it integrates reinforced NGW-type planetary gear structure, corrosion-resistant alloy housing, and explosion-proof sealed design. The product features strong overload capacity, excellent environmental tolerance, and high operational reliability, capable of stably operating in temperature ranges from -40℃ to +100℃. It is widely applied in petrochemical mixing equipment, marine platform machinery, food processing lines, and coal mine auxiliary systems, providing safe and reliable power support for global harsh-environment industrial fields.
II. Core Advantages
1. Reinforced NGW Planetary Structure, Heavy-Load & Anti-Impact
Adopting the reinforced NGW-type planetary gear transmission design, the reducer realizes heavy-load power transmission through the meshing of high-strength sun gear, 4-5 planetary gears, and hardened inner gear ring. The multi-planetary symmetric layout evenly distributes load, reducing single-gear stress by 70% and enabling it to withstand 200% rated torque impact load. Gears are made of premium 20CrNi2Mo alloy steel, processed by integral forging, deep carburizing and quenching, and precision grinding, with tooth surface hardness reaching HRC 62-65 and roughness ≤Ra 0.05μm. Advanced tooth profile modification technology ensures a meshing contact area of over 99%, with transmission efficiency up to 96%-98%. The transmission ratio range covers 3:1 to 100:1, and the single-stage back gap is ≤1.5 arcmin, fully meeting the heavy-load and precision requirements of harsh-environment equipment.
2. Full Model Coverage (FADR47-FADR200), Environment-Adaptive Design
The FADR series covers six core models: FADR47, FADR64, FADR90, FADR110, FADR140, and FADR200, with rated power ranging from 0.3kW to 120kW and rated torque covering 30Nm to 25000Nm, forming a complete heavy-duty product matrix. The housing adopts differentiated corrosion-resistant materials: FADR47-FADR90 use 316L stainless steel for food/marine scenarios, while FADR110-FADR200 adopt explosion-proof cast iron with anti-corrosion coating for petrochemical/coal mine use. The compact integrated structure has a volume 25% smaller than traditional heavy-duty reducers with the same torque, adapting to limited installation space of offshore platforms and workshop equipment. Modular interfaces support servo motor flange connection, keyway input, and hollow shaft with locking disk output, enabling flexible matching with special industrial equipment.
3. Explosion-Proof Sealed Housing, Wide Temperature & Corrosion Resistance
The housing adopts explosion-proof structural design, complying with Ex d隔爆 standard for hazardous areas, with flameproof joints and spark-free internal components. Stainless steel models undergo full-surface polishing and passivation treatment, resisting acid, alkali, and salt corrosion, while cast iron models use multi-layer anti-rust and high-temperature coating. The IP67 protection level prevents dust, heavy water spray, and temporary immersion, ensuring stable operation in humid, dusty, and corrosive environments. The planetary carrier adopts a reinforced crossbeam structure, with torsion stiffness ≥9Nm/arcmin, maintaining stability under high-frequency dynamic load. Equipped with SKF heavy-duty cylindrical滚子轴承, the shaft system bears radial force 40% higher than ordinary bearings, with service life exceeding 28000 hours under normal working conditions.
4. Specialized Lubrication System, Low-Maintenance & Safe
The reducer adopts specialized wide-temperature lubrication: FADR47-FADR90 use food-grade synthetic grease (for food industry) or low-temperature synthetic grease (for -40℃ scenarios), while FADR110-FAD200 adopt explosion-proof oil bath lubrication with high-flash-point gear oil. The housing is equipped with explosion-proof oil level gauge and sealed oil drain port, facilitating maintenance in hazardous areas. Sealing parts use fluorine rubber O-rings and skeleton oil seals, resisting corrosion and high temperature, effectively preventing lubricant leakage. The recommended maintenance cycle is 12000 hours for oil-lubricated models and 8000 hours for grease-lubricated models, with a self-diagnostic oil quality sensor option, reducing maintenance risks in harsh environments.
III. Typical Application Fields
- Petrochemical Industry: Explosion-proof mixers, storage tank agitators, pipeline transport pumps (FADR110-FADR200 for heavy-load equipment)
- Marine & Offshore: Offshore platform winches, ship deck machinery, resisting salt spray corrosion
- Food Processing: High-corrosion conveyor lines, aquatic product processing equipment (316L models for hygiene requirements)
- Coal Mine & Mining: Auxiliary ventilation fans, scraper conveyor auxiliary systems, explosion-proof and dust-proof
- Pharmaceutical & Chemical: Corrosive material reactors, clean room transmission equipment, meeting hygiene and anti-corrosion standards

V. Installation & Maintenance
Select models based on load, explosion-proof grade, and corrosion requirements. During installation, ensure coaxiality error ≤0.03mm and use explosion-proof bolts for hazardous areas. Food-grade models use dedicated food-safe lubricants; low-temperature models adopt synthetic low-temperature grease. Regularly check oil/grease quality and replace every 8000-12000 hours. Avoid collision of the explosion-proof housing and regularly inspect flameproof joints. Stop immediately for inspection if abnormal noise, leakage, or temperature rise occurs, and perform maintenance by professional explosion-proof technicians.
