2.1 Professional Vertical Right-Angle Transmission Design
DBY/DCY series features a unique vertical right-angle transmission structure with perpendicular input and output shafts, perfectly adapting to space-limited vertical installation and layout requirements of conveying and heavy-duty machinery. Compared with parallel shaft reducers, it optimizes equipment spatial layout, saves overall installation space, and avoids structural interference of on-site equipment. The professional transmission layout realizes centralized and reasonable force bearing, providing targeted transmission solutions for vertical driving working conditions that conventional reducers cannot adapt to.
2.2 280kN·m High Torque & Super Strong Bearing Capacity
With a maximum output torque of 280kN·m, the DBY/DCY reducer possesses outstanding heavy-load bearing capacity and stable power reserve. Core gears are made of high-strength low-carbon alloy steel, processed through strict carburizing, quenching and precision grinding, reaching grade 6 high precision with tooth surface hardness up to HRC58-62. The optimized multi-tooth meshing structure ensures uniform force distribution, which can effectively resist frequent start-stop, forward-reverse switching and instantaneous impact loads during long-term full-load operation. It maintains stable torque output without tooth breakage, wear or torque attenuation, ensuring reliable heavy-duty operation.
2.3 High Transmission Efficiency & Energy-Saving Operation
Adopting optimized arc bevel and cylindrical gear meshing technology, the series effectively reduces internal friction and power loss. The overall transmission efficiency is far higher than traditional ordinary reducers, maintaining efficient and stable operation even under long-term heavy-load and continuous cyclic working conditions. It supports 24-hour uninterrupted industrial production, effectively reducing equipment energy consumption and long-term operating costs, fully meeting modern energy-saving and high-efficiency industrial production standards.
2.4 Compact Structure & Lightweight Body
Compared with traditional reducers with the same power and torque level, DBY/DCY series integrates advanced structural optimization technology, featuring smaller overall volume, lighter weight and more compact layout. The highly integrated design simplifies internal structure while ensuring structural rigidity, effectively reducing equipment self-weight and installation occupation space, improving on-site assembly efficiency and equipment integration rationality.
2.5 Low Vibration, Low Noise & High Stability
Through precise tooth profile correction and meshing clearance optimization, the gear meshing process is smooth and accurate. The whole machine operates with ultra-low vibration and low noise without resonance during full-speed range operation. It has excellent anti-fatigue performance and operational stability, adapting to long-term high-intensity continuous operation requirements of heavy industrial workshops.
2.6 Excellent Harsh Environment Adaptability & Durability
The integral high-rigidity cast iron housing undergoes stress relief treatment to avoid structural deformation under long-term vibration and heavy load. Equipped with a fully sealed protective structure, it has superior dust-proof, moisture-proof and anti-fouling performance. It can operate stably for a long time in dusty mines, humid ports and outdoor open-air working environments, with low failure rate and ultra-long service life, meeting the harsh working condition requirements of heavy industry.
2.7 Standardized Design & Low Maintenance Cost
DBY/DCY series adopts national standard modular design with universal interface and strong product interchangeability, which can perfectly replace old-fashioned reducers and imported similar products. The standardized assembly structure simplifies daily inspection, lubrication and maintenance procedures, with fewer vulnerable parts and convenient on-site disassembly and replacement. It effectively reduces equipment downtime and comprehensive operation and maintenance costs, with prominent cost performance.
