As a core product in Weigao's planetary transmission series, this series is specifically designed to address the pain points of low torque density, poor rigidity, and large volume of traditional reducers in precision motion control scenarios. Compliant with international planetary gear transmission standards and certified by ISO 9001 quality management system and IP65 protection level, it integrates optimized NGW-type planetary gear structure, high-strength alloy steel housing, and modular input/output interfaces. The product features compact structure, high transmission efficiency, strong load-bearing capacity, and excellent motion stability, capable of stably operating in temperature ranges from -20℃ to +60℃. It is widely applied in industrial robot joints, CNC machine tool feed systems, AGV robots, precision assembly lines, and electronic manufacturing equipment, providing high-precision and reliable power transmission support for global high-end manufacturing fields.
II. Core Advantages
1. Optimized NGW Planetary Gear Structure, High Efficiency & Uniform Load Distribution
Adopting the internationally advanced NGW-type planetary gear transmission design, the reducer realizes power transmission through the meshing of sun gear, 3-4 planetary gears, and inner gear ring. The multi-planetary gear structure evenly distributes the load, reducing the stress on a single gear by 60% compared with traditional parallel shaft reducers, and the maximum peak torque can reach 25000N·m. Gears are made of high-quality 20CrNiMo alloy steel, processed by integral forging, carburizing and quenching, and super-precision grinding, with tooth surface hardness reaching HRC 60-64 and roughness ≤Ra 0.08μm. The optimized tooth profile modification technology ensures a meshing contact area of over 98%, realizing smooth and efficient transmission with efficiency up to 96%-98%. The transmission ratio range covers 3:1 to 100:1, and different reduction ratios can be flexibly configured according to needs, fully meeting the precision speed regulation requirements of high-end equipment.
2. Full Model Coverage (FAB42-FAB180), Strong Adaptability
The FAB series covers six core models: FAB42, FAB60, FAB90, FAB115, FAB142, and FAB180, with rated power ranging from 0.1kW to 75kW and rated torque covering 11Nm to 18000Nm, forming a complete product matrix to meet the differentiated needs of different precision equipment. The modular structural design supports multiple input/output forms, including servo motor direct connection, flange input, solid shaft output, hollow shaft with locking disk, and spline shaft output, which can be flexibly matched with various driving and driven equipment. The compact structure design makes the volume 30% smaller than that of traditional reducers with the same torque, easily fitting into the limited installation space of equipment such as robot joints and precision machine tools.
3. High-Rigidity Cast Iron Housing, Reliable & Durable
The housing and planetary carrier are made of high-strength nodular cast iron (FAB42-FAB90) and alloy steel (FAB115-FAB180) respectively, formed by integral casting and precision machining. Finite element simulation optimization is applied to the internal structure, and key stress-bearing parts are equipped with reinforced rib networks, enhancing overall rigidity and anti-impact capacity. The planetary carrier adopts a crossbeam integrated structure, with torsion stiffness ≥5Nm/arcmin, ensuring stable transmission under high dynamic load conditions. The surface is treated with anti-rust, anti-corrosion, and high-temperature resistant painting, and the IP65 protection level effectively prevents dust, water spray, and other pollutants from entering, adapting to complex industrial environments. Equipped with high-precision angular contact ball bearings, the shaft system operates stably with low friction, and the service life exceeds 20000 hours under normal working conditions.
4. Integrated Lubrication System, Convenient Maintenance
The gear unit adopts integrated oil bath lubrication design, with factory-filled special high-temperature resistant extreme pressure gear oil, enabling immediate use after installation. The housing is equipped with a transparent high-temperature resistant oil level observation window, a centralized oil filling port, and a quick-opening oil drain port, facilitating daily lubrication management and maintenance. The lubrication system is optimized for long-term high-speed operation, with a recommended oil change cycle of 6000 hours under normal working conditions, greatly reducing maintenance frequency and downtime cost. The sealed structure adopts high-quality skeleton oil seals and O-rings, effectively preventing oil leakage and ensuring clean operation of precision equipment.

V. Installation & Maintenance
Select the corresponding model (FAB42-FAB180) according to the load and space requirements. During installation, ensure the coaxiality error between the reducer and the motor/driven equipment is ≤0.02mm to avoid affecting transmission precision. Use high-strength bolts with anti-loosening devices to fix the reducer firmly on the mounting base. Select appropriate lubricating oil according to the working environment: use 220# high-temperature resistant extreme pressure gear oil for normal temperature conditions. Regularly check the oil level through the observation window, and replace the lubricating oil every 6000 hours of operation or once a year. Keep the surface of the housing clean to facilitate heat dissipation. Stop the machine immediately for inspection if abnormal noise, vibration, oil leakage, or excessive temperature rise occurs during operation.
