  • Special reducer for scraper machine

The dedicated reducer for scraper conveyors is a high-efficiency transmission device customized for scraper conveyors, mainly used to convert the high-speed rotational motion of the motor into low-speed, high-torque output to drive the scraper chain for stable operation. Its structure adopts multi-stage gear transmission (such as the planetary + parallel shaft structure shown in the picture), including high-speed stage reduction, intermediate reversing, and low-speed output functions. The core components are forged from high-strength alloy steel, and the housing is made using cast steel welding technology to ensure long-term reliable operation under heavy load impact and frequent start-stop conditions. This reducer is the core power unit ensuring continuous material transportation of the scraper conveyor.

Product Applications

1. Coal Industry: Underground scraper conveyors and transfer machine drives in coal mines, achieving efficient raw coal transportation.

2. Mining Sector: Material transfer systems in metal and non-metal mining operations.

3. Building Materials Industry: Transportation of clinker and gypsum in cement plants; material distribution in sand and gravel aggregate production lines.

4. Power Industry: Coal bunker feeders and slag handling systems in thermal power plants.

5. Port Logistics: Drive systems for scraper feeders in bulk material conveying systems.

Product Features

1. Ultra-high Load Capacity: Uses hardened tooth surface gears (precision GB 10 grade), with a maximum output torque of 8000 kN·m, suitable for ultra-heavy scraper conveyors (e.g., width over 1.4m).

2. Intelligent Lubrication System: Integrated constant temperature oil station (as shown by the oil pipes in the picture), automatically controlling oil temperature between 35~55°C, extending lubricant life by 40%.

3. Heavy-duty Impact Resistance Design: Bearings selected from SKF/NSK brands, increasing load capacity by 30%, with impact load resistance up to 2.5 times the rated torque.

4. Low Noise and Stable Operation: Gears are precision ground, noise level below 78 dB(A), vibration intensity ≤4.5 mm/s (ISO 10816 standard).

5. Maintenance-free Structure: Sealing uses dual protection with labyrinth and oil seals, dust and water protection rating IP65, maintenance interval ≥1 year.

Product Functions

1. Torque Amplification: Amplifies motor torque by 5 to 100 times to meet scraper chain startup and full-load requirements.

2. Precise Speed Control: Customizable gear ratios (i=10~200) to achieve output speeds of 5~100 r/min, ensuring material transport rhythm.

3. Overload Protection: Built-in shear pin/hydraulic coupling (as shown in the coupling picture), instantaneous overload protection up to 180%.

4. Bidirectional Drive Support: Capable of forward and reverse output, suitable for bidirectional scraper conveyor processes.

5. Remote Monitoring Compatibility: Reserved interfaces for temperature/vibration sensors, supporting industrial IoT integration.
