I. Product Overview
Weigao FABR Series Planetary Reducers, covering full models from FABR42 to FABR180, are enhanced high-precision transmission devices tailored for high-end equipment in harsh working conditions requiring high torque, strong impact resistance, and stable precision transmission. As an upgraded flagship product in Weigao's planetary transmission series, this series is specifically designed to address the pain points of poor impact resistance, narrow temperature adaptation range, and insufficient torque reserve of traditional precision planetary reducers in complex dynamic load scenarios. Compliant with international advanced planetary gear transmission standards and certified by ISO 9001 quality management system and IP67 protection level, it integrates enhanced NGW-type planetary gear structure, high-strength alloy steel integral housing, and modular servo-adaptive input/output interfaces. The product features strong impact resistance, high transmission precision, wide temperature adaptation, and long service life, capable of stably operating in temperature ranges from -30℃ to +80℃. It is widely applied in heavy-duty industrial robot joints, CNC machine tool spindle systems, automated warehouse stackers, new energy equipment, and precision heavy-load transmission scenarios, providing reliable high-precision power support for global high-end manufacturing and harsh environment industrial fields.
II. Core Advantages
1. Enhanced NGW Planetary Gear Structure, Strong Impact Resistance & Uniform Load Distribution
Adopting the enhanced NGW-type planetary gear transmission design, the reducer realizes efficient power transmission through the meshing of high-strength sun gear, 4-5 planetary gears, and reinforced inner gear ring. The multi-planetary gear symmetric layout evenly distributes the load, reducing the stress on a single gear by 70% compared with traditional planetary reducers, and the maximum peak impact torque can reach 30000N·m, which is 20% higher than the standard series. Gears are made of premium 20CrNi2Mo alloy steel, processed by integral forging, deep carburizing and quenching, and super-precision grinding, with tooth surface hardness reaching HRC 62-65 and roughness ≤Ra 0.05μm. The advanced tooth profile modification and crown optimization technology ensure a meshing contact area of over 99%, realizing smooth and efficient transmission with efficiency up to 97%-99%. The transmission ratio range covers 3:1 to 100:1, and the single-stage back gap is ≤1 arcmin, fully meeting the high-precision positioning and dynamic load resistance requirements of harsh environment equipment.
2. Full Model Coverage (FABR42-FABR180), Wide Scene Adaptation
The FABR series covers six core models: FABR42, FABR60, FABR90, FABR115, FABR142, and FABR180, with rated power ranging from 0.2kW to 110kW and rated torque covering 15Nm to 22000Nm, forming a complete high-performance product matrix to meet the differentiated needs of light, medium, and heavy-duty precision transmission equipment. The modular structural design supports multiple input/output forms, including servo motor direct flange connection, keyway input, solid shaft with flat key output, hollow shaft with locking disk, and spline shaft output, which can be flexibly matched with various high-end servo motors and driven equipment. The compact integrated structure makes the volume 25% smaller than that of traditional enhanced reducers with the same torque, easily fitting into the limited installation space of precision equipment such as heavy-duty robot joints and stackers.
3. High-Strength Integral Housing, Wide Temperature Domain & Reliable Protection
The housing and planetary carrier are made of high-strength alloy steel (FABR42-FABR90) and high-toughness nodular cast iron (FABR115-FABR180) respectively, formed by integral casting and precision machining. The internal structure is optimized through advanced finite element simulation, and key stress-bearing parts are equipped with dense reinforced rib networks, enhancing overall rigidity and anti-vibration capacity. The planetary carrier adopts a reinforced crossbeam integrated structure, with torsion stiffness ≥8Nm/arcmin, ensuring stable transmission under high-frequency dynamic load and strong impact conditions. The surface is treated with multi-layer anti-rust, anti-corrosion, and high-temperature resistant coating, and the IP67 protection level effectively prevents dust, heavy water spray, and temporary immersion, adapting to complex harsh industrial environments. Equipped with high-precision double-row angular contact ball bearings with preload, the shaft system operates stably with low friction, and the service life exceeds 25000 hours under normal working conditions.
4. Intelligent Lubrication & Heat Dissipation System, Convenient Maintenance
The gear unit adopts intelligent circulating oil bath lubrication design, with factory-filled special wide-temperature extreme pressure gear oil, enabling immediate use after installation. The housing is equipped with a high-temperature resistant transparent oil level observation window, a centralized oil filling port, and a quick-opening oil drain port with filter, facilitating daily lubrication management and maintenance. The built-in enhanced heat dissipation fins and optional forced cooling fan (for FABR115-FABR180 high-power models) ensure efficient heat dissipation even under continuous heavy-load operation. The lubrication system is optimized for long-term high-speed and wide-temperature operation, with a recommended oil change cycle of 8000 hours under normal working conditions, greatly reducing maintenance frequency and downtime cost. The sealed structure adopts high-quality imported skeleton oil seals and O-rings, effectively preventing oil leakage and ensuring clean operation of precision equipment.

V. Installation & Maintenance
Select the corresponding model (FABR42-FABR180) according to the load, torque, and temperature requirements. During installation, ensure the coaxiality error between the reducer and the motor/driven equipment is ≤0.01mm 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 320# wide-temperature extreme pressure gear oil for normal temperature conditions, and special low-temperature gear oil for low-temperature environments below -20℃. Regularly check the oil level through the observation window, and replace the lubricating oil every 8000 hours of operation or once a year. Keep the surface of the housing and heat dissipation fins clean to ensure efficient heat dissipation. Stop the machine immediately for inspection if abnormal noise, vibration, oil leakage, or excessive temperature rise occurs during operation.
