Product Introduction

The DBY and DCY series are bevel-helical gear reducers, combining bevel gears for right-angle power transmission and helical gears for high torque and smooth operation. They are widely used in heavy-duty applications such as mining, cement, metallurgy, and conveyor systems.

Features:

1. Gear Configuration

• First Stage: Spiral bevel gear (for 90° shaft direction change).Second & Third Stages: Helical gears (for high torque transmission).Hardened & precision-ground gears for durability and efficiency.

2. Housing & Construction

• Material: High-strength cast iron (HT250) for rigidity and vibration damping. Design: Vertical or horizontal mounting options available.

3. Reduction Ratio & Power Range

• DBY (Two-Stage Reduction) Ratio: 8:1 to 14:1 Output Torque: Up to 18,000 Nm Power Range: Up to 200 kW
• DCY (Three-Stage Reduction) Ratio: 16:1 to 100:1 Output Torque: Up to 50,000 Nm Power Range: Up to 1,000 kW

4. Efficiency & Lubrication

• High efficiency (~94-96% per stage due to helical gears).
• Oil bath lubrication (some models may include forced lubrication for heavy loads).

Applications

• Heavy industries: Mining conveyors, crushers, ball mills, cranes.
• Cement plants: Rotary kilns, mixers.
• Metallurgy: Rolling mills, extruders.
