The parallel shaft reducer is a core transmission device that achieves speed reduction and torque increase using the principle of parallel shaft gear transmission. Its structure includes high-speed stage parallel shaft gear meshing, converting the motor's high speed and low torque into low speed and high torque output through multi-stage gear reduction. It features efficient transmission, low noise, and high reliability. The housing is made of high-strength cast iron or welded cast steel, with reliable sealing, suitable for continuous heavy-duty conditions, and is a key component for driving fans, pumps, conveyors, and other equipment.
Product Applications
1. Power and Energy: Drives for forced draft fans and feed water pumps in thermal power plants, ensuring stable unit operation.
2. Petrochemical: Reducers for oilfield pumping units and chemical pump drives, suitable for high temperature and corrosive environments.
3. Building Materials and Metallurgy: Drives for cement plant roller presses and steel mill rolling machines, enabling efficient material processing.
4. Heavy Machinery: Travel mechanisms for port cranes and slewing devices for excavators, providing high torque output.
5. Logistics and Transportation: Drives for conveyor lines and lifts, ensuring smooth material handling.
Product Features
1. High Load Capacity: Uses high-strength alloy steel gears (20CrMnTi) with carburizing and quenching treatment, gear surface hardness HRC58-62, maximum output torque up to 800kN·m, suitable for ultra-heavy load equipment.
2. Efficient Transmission: Hard tooth surface gears with GB grade 10 precision, transmission efficiency >97%, saving 10%~15% energy.
3. Intelligent Lubrication: Integrated constant temperature oil station (as shown by the oil pipe in the picture), automatic oil temperature control between 40~60°C, extending lubricant life by 30%.
4. Low Noise Operation: Gears are precision ground, noise below 80dB(A), vibration intensity ≤4.5mm/s (ISO 10816 standard).
5. Compact Structure: Parallel shaft three-stage transmission design, saving 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 by 5~100 times to meet low-speed heavy load requirements.
2. Speed Regulation: Achieves precise output speed control from 0.5 to 1000 r/min through customized gear ratios (i=10~500).
3. Overload Protection: Built-in safety coupling (as shown in the coupling part of the picture), instantaneous overload protection capacity up to 180%.
4. Direction Change: Supports 90° direction change (as shown by the orthogonal output), flexibly adapting to equipment layout.
5. Maintenance-Free Design: NSK/SKF bearings with lifetime lubricating grease, maintenance cycle ≥2 years, reducing downtime risk.
