2.1 Ultra-Wide Parameter Coverage & Super Strong Versatility
The HB series covers a full power range from 4kW to 6000kW and a flexible speed ratio range of 1.25 to 450, supporting ultra-low ratio high-speed operation and ultra-high ratio low-speed heavy-torque output. It realizes flexible switching of multiple operating modes, fully meeting diversified process requirements of various large industrial equipment. The universal modular design avoids repeated model selection and equipment modification, greatly improves equipment matching efficiency, and effectively reduces overall procurement and operating costs.
2.2 950kN·m Maximum Torque, Outstanding Heavy-Load & Impact Resistance
With a maximum output torque up to 950kN·m, the HB industrial gear unit possesses industry-leading 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 meshing structure ensures uniform force distribution, which can effectively resist instantaneous impact load, frequent start-stop and forward-reverse alternating load in heavy industrial scenarios. It avoids gear wear, tooth breakage and torque attenuation, ensuring long-term stable full-load operation.
2.3 High Rigidity Structure & Ultra-Stable Operation
The whole machine adopts integral high-rigidity cast iron housing with stress relief treatment, which effectively prevents structural deformation and oil leakage under long-term heavy vibration and overload conditions. Precision gear machining and meshing optimization ensure smooth transmission, low vibration and low noise during high-intensity cyclic operation. It maintains excellent operating stability and positioning accuracy under continuous heavy-load working conditions, adapting to strict industrial production standards.
2.4 High Transmission Efficiency & Energy Saving
Adopting optimized helical and bevel-helical transmission structure, the gearbox effectively reduces internal friction and power loss. The overall transmission efficiency is extremely high with low energy consumption, even during long-term low-speed heavy-load operation. It supports 24-hour uninterrupted industrial continuous production, effectively reducing equipment energy consumption and comprehensive operating costs, conforming to modern green and efficient industrial manufacturing requirements.
2.5 Excellent Harsh Environment Adaptability & Long Service Life
Equipped with upgraded fully sealed protection structure, the HB series has superior dust-proof, moisture-proof, corrosion-resistant and high-temperature resistant performance. It can operate stably for a long time in dusty mining sites, high-temperature metallurgical workshops, humid port environments and other harsh industrial scenarios. High wear-resistant core components and reliable structural design greatly extend the service life and reduce equipment failure rate.
