GUOMAO ZY Series Cylindrical Gear Reducer
The GUOMAO ZY Series Cylindrical Gear Reducer is a heavy-duty hard-tooth surface parallel shaft transmission equipment developed for full-condition industrial heavy-load working scenarios. Adopting high-precision cylindrical helical gear transmission principle, high-strength alloy steel carburizing and quenching process and integral high-rigidity housing structure, this series features ultra-wide power and speed ratio coverage, 520kN·m large torque output, high transmission efficiency, strong impact resistance and long-term stable continuous operation. It perfectly integrates high-speed precision transmission and low-speed heavy-torque driving performance, effectively making up for the insufficient load capacity and narrow parameter range of traditional ordinary reducers. With standardized modular design, strong versatility and excellent harsh environment adaptability, it has become a core universal heavy-duty transmission product for metallurgy, mining, building materials, chemical and large conveying equipment.

2.1 Full-Condition Ultra-Wide Parameter Coverage
2.2 520kN·m Stable Heavy Torque & Outstanding Overload Resistance
With a maximum output torque of 520kN·m, the ZY cylindrical gear reducer has excellent heavy-load bearing capacity and sufficient power reserve. Core gears are made of high-quality alloy steel, processed through strict carburizing, quenching and precision grinding, with tooth surface hardness up to HRC58-62. The optimized symmetrical meshing structure ensures uniform force distribution, which can effectively resist instantaneous impact load, frequent start-stop and forward-reverse alternating load in heavy industrial production. It maintains stable torque output without power attenuation, gear wear or tooth breakage during long-term full-load operation, ensuring reliable heavy-duty driving.
2.3 High Transmission Precision & Ultra-High Efficiency
Adopting professional tooth profile correction and high-precision gear finishing technology, the ZY series achieves smooth and accurate gear meshing with extremely low internal friction loss. Compared with traditional reducers, it has higher transmission efficiency and lower energy consumption, maintaining efficient operation even under long-term low-speed heavy-load conditions. It supports 24-hour uninterrupted high-intensity cyclic production, effectively reducing long-term equipment operating energy consumption and comprehensively lowering enterprise production costs.
2.4 High Structural Rigidity & Strong Operational Stability
The whole machine adopts integral thickened cast iron housing with secondary stress relief treatment, which effectively eliminates structural internal stress and avoids deformation and oil leakage caused by long-term heavy vibration and overload. The optimized parallel shaft layout features reasonable force-bearing structure, low vibration and low noise during operation, no resonance in full speed range, and excellent operational stability and anti-fatigue performance, fully adapting to strict industrial production standards.
2.5 Wide Temperature Adaptability & Harsh Environment Resistance
The ZY series is designed for complex industrial environments, with a working temperature range of -40℃ to 45℃, supporting stable start-up and operation in ultra-low temperature and high-temperature scenarios. Equipped with a fully sealed protective structure, it has excellent dust-proof, moisture-proof and anti-corrosion performance, and can operate stably for a long time in dusty mining sites, high-temperature workshops, humid outdoor environments and other harsh conditions, with ultra-low failure rate and long service life.
2.6 Good Interchangeability & Low Maintenance Cost
Adopting national standard modular design and universal dimensional interface, the product has high interchangeability with domestic and international mainstream similar products. It supports various installation forms and diversified shaft types, with strong compatibility and convenient on-site assembly and replacement. The standardized structural design simplifies daily inspection, lubrication maintenance and fault maintenance procedures, effectively reducing equipment downtime and long-term comprehensive operation and maintenance costs.
