Hardened gear reducers are divided into parallel shaft and vertical shaft structures. The DCY reducer adopts a vertical shaft structure, with the high-speed stage utilizing Gleason spiral bevel gears and the subsequent two stages employing involute helical cylindrical gears.

Performance characteristics:
1) Key parameters such as center distance and nominal transmission ratio have been optimized through design, ensuring high interchangeability of major components.
2) Gears are manufactured from high-quality alloy steel through carburizing and quenching processes, achieving a tooth surface hardness of HRC 54-62.
3) Compact size, light weight, high precision, strong load capacity, high efficiency, long service life, high reliability, smooth transmission, and low noise.
Suitable for industrial sectors including metallurgy, mining, chemical engineering, building materials, lifting, transportation, textiles, papermaking, instruments, plastics, rubber, engineering machinery, and energy.

After the initial operation of 300-600 hours, the lubricating oil needs to be replaced. Subsequently, the oil should be changed every 1500-5000 hours of operation, depending primarily on the working environment. However, the interval must not exceed 12 months. During oil changes, contaminants inside the housing should be cleaned.
