2.1 Full-Condition Ultra-Wide Parameter Coverage
The HB series covers an ultra-wide power range from 4kW to 6000kW and a flexible speed ratio range of 1.25 to 450, fully covering high-speed light-load fine transmission and ultra-low-speed ultra-heavy-torque output demands. It supports diversified working condition switching of various large industrial equipment, realizing flexible matching of multiple processes. The complete parameter portfolio eliminates repeated model selection and equipment structural modification, greatly improves equipment versatility, and meets the personalized transmission needs of various large complete sets of industrial equipment.
2.2 950kN·m Super Large Torque & Outstanding Heavy-Load Resistance
With a maximum output torque up to 950kN·m, the HB industrial gearbox has industry-leading ultra-heavy load bearing capacity and sufficient power reserve. Core gears are made of high-strength alloy steel, processed through carburizing, quenching and precision tooth modification treatment. The optimized multi-tooth uniform meshing structure disperses load pressure effectively, enabling stable resistance to instantaneous impact load, frequent start-stop and forward-reverse alternating load. It maintains stable torque output without power attenuation, tooth breakage or slipping under long-term full-load operation, ensuring reliable heavy-duty operation of large equipment.
2.3 High-Rigidity Integrated Structure & Extreme Stability
The whole machine adopts integral thickened cast iron housing with professional stress relief annealing treatment, which effectively avoids structural deformation, vibration displacement and oil leakage under long-term heavy vibration and ultra-heavy load conditions. The internal structural layout is optimized for heavy-load force bearing, with strong overall rigidity and structural stability. It operates smoothly with low vibration and low noise during 24-hour high-intensity cyclic operation, fully meeting the strict stable operation standards of modern heavy industrial production.
2.4 High Transmission Efficiency & Energy-Saving Operation
Adopting advanced helical and bevel-helical composite transmission structure, the gearbox minimizes internal friction and power loss. It maintains high transmission efficiency even under ultra-heavy load and low-speed extreme working conditions, with lower energy consumption compared with traditional heavy-duty reducers. It supports long-term uninterrupted industrial continuous production, effectively reducing comprehensive equipment operating costs and conforming to modern green and high-efficiency heavy industrial manufacturing requirements.
2.5 Excellent Harsh Environment Adaptability & Long Service Life
Equipped with upgraded fully sealed multi-layer protection structure, the HB series has superior dust-proof, moisture-proof, high-temperature resistant and anti-corrosion performance. It can operate stably for a long time in dusty mining sites, high-temperature metallurgical workshops, humid port environments and corrosive chemical scenarios. The high wear-resistant and anti-fatigue core components greatly extend the service life and reduce equipment failure rate in complex harsh working conditions.
2.6 Diversified Flexible Installation & Low Maintenance Cost
Support multiple installation methods including foot mounting, flange mounting and torque arm mounting, with diversified output shaft forms such as solid shaft, hollow shaft and spline shaft. It features universal standard interface, high compatibility with various large-scale host equipment and good interchangeability with imported products. The standardized modular assembly structure simplifies daily inspection, disassembly and maintenance procedures, effectively reducing equipment downtime and later comprehensive maintenance costs.
