Bevel gear reducer is a mechanical device that uses the principle of bevel gear transmission to achieve speed reduction and torque increase. Its core structure includes a pair of bevel gears with intersecting axes (usually at a 90° angle). Through high-speed stage reduction and direction conversion, it converts the motor's high speed and low torque into low speed and high torque output, while also providing noise reduction, speed stabilization, and overload protection functions. This reducer features a compact structure, high transmission efficiency (>95%), and smooth operation, making it a key component for achieving spatial intersecting shaft transmission in industrial fields.
Product Applications
1. Lifting and Transportation: Port crane slewing drive, elevator transmission systems.
2. Mining Machinery: Transmission for ball mills and crushers, enabling power conversion between vertical and horizontal directions.
3. Energy Industry: Wind power gearboxes, pumpjack reducers, suitable for extreme cold and high-temperature environments.
4. Heavy Machine Tools: Feed mechanisms for rolling mills and gantry milling machines, ensuring machining accuracy.
5. Logistics Equipment: Automated warehouse stackers, conveyor line steering devices.
Product Features
1. High Efficiency Transmission: Hardened tooth surface bevel gears with precision up to GB Grade 6, transmission efficiency over 95%, saving 15% energy.
2. Wide Speed Ratio Range: Single-stage ratio from 3 to 6, multi-stage combinations can exceed 100, adaptable to various working conditions.
3. Spatial Direction Change: Achieves 90° offset between input and output shafts, allowing flexible layout (such as vertical output structure shown in the image).
4. Low Noise Operation: Gears are precision ground, noise level below 78dB(A), vibration intensity ≤3.5mm/s.
5. High Reliability: Bearings selected from imported brands (SKF/NACHI), MTBF exceeds 20,000 hours.
Product Functions
1. Torque Amplification: Amplifies motor torque by 5 to 100 times to meet low-speed, high-load requirements.
2. Direction Conversion: Achieves 90° spatial power transmission through bevel gears (as shown in the image).
3. Overload Protection: Built-in shear pins/hydraulic couplers provide instantaneous overload protection up to 200%.
4. Intelligent Lubrication: Integrated constant temperature oil station (oil pipes shown in the image), automatically controls oil temperature between 40~60°C.
5. Backstop Function: Optional backstop device (shown at the right shaft end in the image) to prevent reverse rotation of heavy load equipment.
