Industry-specific gear reducers are the core devices for power transmission between high-speed motors and low-speed working machinery. Through multi-stage gear meshing (such as the planetary gear + parallel shaft structure shown in the picture), they convert 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 adopts a modular design, allowing customization of gear ratios and load capacities according to working conditions. It is widely used in heavy-duty, high-precision transmission scenarios and is a key component in mining machinery, lifting and transportation, and energy equipment fields.
Product Applications
1. Mining Machinery: Drives ball mills, crushers, and scraper conveyors to achieve efficient ore crushing and material transportation.
2. Lifting and Transportation: Used in the slewing mechanisms and hoisting systems of port cranes and elevators to ensure smooth operation under heavy loads.
3. Energy Industry: Wind turbine gearboxes and pump jack reducers, suitable for harsh conditions such as extreme cold and high temperatures.
4. Construction Machinery: Travel devices for excavators and road rollers, providing high torque output.
5. Heavy Machine Tools: Feed systems for rolling mills and gantry milling machines, ensuring machining accuracy and stability.
Product Features
1. High Load Capacity: Uses high-strength alloy steel gears and cast steel housings, with a maximum load torque of 5000 kN·m, suitable for ultra-heavy-duty equipment.
2. High Efficiency Transmission: Hardened gear teeth precision reaches GB Grade 6, transmission efficiency >97%, saving 10%~15% energy.
3. Intelligent Lubrication: Integrated constant temperature oil station (as shown by the oil pipes in the picture), automatically controlling oil temperature between 40~60°C, extending gear life by 30%.
4. Low Noise Operation: Gears undergo precision shaving treatment, noise level below 75 dB(A), compliant with GB 10056 standard.
5. Maintenance-Free Design: Bearings selected from SKF/NACHI brands, maintenance cycle ≥5 years, reducing downtime risks.
Product Functions
1. Torque Amplification: Amplifies motor torque by 5~100 times to meet low-speed, heavy-load working conditions.
2. Speed Regulation: Customizable gear ratios (i=10~1000) enable precise output speed control from 5 to 1000 r/min.
3. Overload Protection: Built-in shear pins/hydraulic couplers (as shown in the coupling picture) provide instantaneous overload protection up to 200%.
4. Direction Change: Supports 90° steering (hypoid bevel gears) or coaxial output, flexibly adapting to equipment layouts.
5. Vibration and Noise Reduction: Elastic couplings plus housing vibration damping pads, vibration intensity ≤2.8 mm/s (ISO 10816 standard).
