Cylindrical gear reducer is a mechanical device that uses the principle of cylindrical gear transmission to achieve speed reduction and torque increase. Its core structure includes multi-stage cylindrical gear meshing, which converts the motor's high speed and low torque into low speed and high torque output through high-speed stage deceleration and low-speed stage torque amplification. The housing is made of cast iron or welded cast steel, with reliable sealing, suitable for continuous heavy-duty operation. It is widely used in mining, building materials, energy, heavy industry, and other fields, serving as a key component for driving ball mills, crushers, conveyors, and other equipment.
Product Applications
1. Mining Industry: Main drive systems for ball mills, crushers, and scraper conveyors.
2. Building Materials Field: Cement rotary kilns, roller presses, vertical mill reducers.
3. Energy Industry: Fans and pumps in thermal power plants, pump jacks drive.
4. Heavy Machinery: Port cranes, excavator travel devices.
5. Chemical and Petroleum: Agitation equipment, pump drives.
Product Features
1. High Load Capacity: Uses high-strength alloy steel gears (20CrMnTi), carburized and quenched, gear surface hardness HRC58-62, maximum output torque up to 1000kN·m.
2. High Transmission Efficiency: Hardened gear surface precision GB grade 10, transmission efficiency >97%, energy saving 15%~20%.
3. Smooth Operation: Gears are precision ground, noise below 80dB(A), vibration intensity ≤4.5mm/s (ISO 10816 standard).
4. Intelligent Lubrication: Integrated constant temperature oil station, oil temperature automatically controlled between 40~60℃, lubrication oil life extended by 30%.
5. Compact Structure: Parallel shaft three-stage transmission design, saves 30% installation space.
6. Strong Adaptability: Supports horizontal/vertical installation, customizable explosion-proof type (Ex d IIB T4).
Product Functions
1. Torque Amplification: Amplifies motor torque 5~100 times to meet low-speed heavy load requirements.
2. Speed Regulation: Customizable speed ratio (i=10~500) to achieve precise output speed control from 0.5 to 1000 r/min.
3. Overload Protection: Built-in safety coupling with instantaneous overload protection capacity up to 180%.
4. Direction Change: Supports 90° direction change, flexibly adapting to equipment layout.
5. Maintenance-Free Design: Bearings selected from SKF/NACHI brands, maintenance cycle ≥2 years, reducing downtime risk.
