FBR Series Planetary Reducer (FBR60/FBR90/FBR115/FBR142/FBR180): Heavy-Shock-Resistant & Extreme-Condition Transmission Solution
I. Product Overview
Weigao FBR Series Planetary Reducers, covering core models from FBR60 to FBR180, are heavy-duty enhanced transmission devices tailored for extreme industrial scenarios requiring strong shock resistance, stable overload operation, and harsh environment adaptability. As a specialized product in Weigao's planetary transmission lineup, this series addresses the pain points of poor impact load resistance, easy gear deformation, and short service life of traditional reducers in heavy-duty shock工况. Compliant with international heavy-duty planetary gear standards and certified by ISO 9001 quality management system and IP67 protection level, it integrates reinforced NGW-type planetary gear structure, gradient-hardened gear set, and integrated shock-absorbing housing design. The product features exceptional anti-shock performance, high fatigue strength, and wide temperature adaptability, capable of stably operating in temperature ranges from -40℃ to +100℃. It is widely applied in heavy-duty cranes, steel mill rolling equipment, road milling machines, and mining machinery, providing reliable power support for global extreme heavy-industry fields.
II. Core Advantages
1. Reinforced NGW Structure with Tooth Topology Optimization, Superior Shock Resistance
Adopting the reinforced NGW-type planetary gear transmission design integrated with tooth形拓扑优化 technology, the reducer realizes stable power transmission under extreme shock through the meshing of high-strength sun gear, 4-5 planetary gears, and hardened inner gear ring. The unique tooth profile optimization design enables ordered force conduction during shock load, controlling gear micro-deformation within millimeters to avoid cumulative damage. Gears are made of premium 20CrNi2Mo alloy steel, processed by integral forging, deep carburizing and quenching, forming a gradient material structure with tough core and hard surface (tooth surface hardness HRC 62-65, roughness ≤Ra 0.05μm). The integrated double-support planetary carrier structure enhances torsion stiffness to ≥12Nm/arcmin, enabling it to withstand 250% rated torque impact load. Transmission efficiency reaches 96%-98% with a ratio range of 3:1 to 100:1, fully meeting heavy-duty shock scenario requirements.
2. Full Model Coverage (FBR60-FBR180), Heavy-Duty Oriented Design
The FBR series covers five core models: FBR60, FBR90, FBR115, FBR142, and FBR180, with rated power ranging from 1.5kW to 150kW and rated torque covering 150Nm to 30000Nm, forming a complete heavy-duty shock-resistant product matrix. The housing adopts high-toughness nodular cast iron for all models, with integrated shock-absorbing rib structures optimized through finite element simulation, effectively dispersing impact force and avoiding housing deformation. The compact design makes the volume 22% smaller than traditional heavy-duty reducers with the same shock resistance, adapting to limited installation space of heavy machinery. Modular interfaces support flange input, keyway connection, and hollow shaft with locking disk output, enabling flexible matching with heavy-duty motors and working equipment.
3. Integrated Shock-Absorbing Housing, Extreme Environment Tolerance
The one-piece cast housing integrates shock-absorbing structures at key stress points, reducing vibration amplitude by 35% during impact load operation. The surface is treated with multi-layer anti-rust, anti-corrosion, and high-temperature resistant coating, with 316L stainless steel fasteners for enhanced durability in corrosive environments. The IP67 protection level effectively prevents dust, heavy water spray, and temporary immersion, ensuring stable operation in dusty, humid, and high-temperature industrial sites. Equipped with SKF heavy-duty cylindrical roller bearings with preload, the shaft system bears radial force 50% higher than ordinary bearings, with service life exceeding 30000 hours under normal heavy-duty working conditions. The pre-stress adjustment process pre-compensates for stress deformation, maintaining optimal meshing state after repeated shocks.
4. Wide-Temperature Lubrication System, Low-Maintenance & Durable
The reducer adopts enhanced oil bath lubrication with special wide-temperature extreme pressure gear oil (-40℃ to 120℃), factory-filled for immediate use. The housing is equipped with a shock-resistant oil level gauge, sealed oil filling port, and filter-equipped oil drain port, facilitating maintenance in heavy-industry environments. The lubrication system is optimized for shock load operation, forming a stable oil film on gear surfaces to reduce wear during impact. The recommended oil change cycle is 12000 hours under normal working conditions, with optional oil quality sensors for real-time monitoring. Sealing parts use fluorine rubber O-rings and reinforced skeleton oil seals, effectively preventing oil leakage even under strong vibration and ensuring long-term clean operation.
