Types and Material Selection of Belts for Combine Harvesters
Combine harvesters are essential machinery in modern agriculture, and the stability of their transmission systems directly affects harvesting efficiency and equipment lifespan. Among the transmission components, belts play a crucial role, making the selection of their types and materials particularly important.
1. Types of Belts for Combine Harvesters
V-Belts
Features: V-shaped cross-section, excellent self-tightening performance, suitable for transmitting large torque.
Applications: Commonly used to drive the power system of combine harvesters, such as the transmission between the engine and the threshing device.
Synchronous Belts
Features: Equipped with toothed profiles to ensure synchronized operation during transmission, preventing slippage and misalignment.
Applications: Used in parts that require precise synchronization, such as the cutting system and conveyor belt transmission.
Multi-V Belts
Features: Composed of multiple V-shaped wedges, offering high transmission efficiency and strong load-bearing capacity.
Applications: Suitable for high-power transmission in heavy-duty combine harvesters.
2. Material Selection for High-Quality Belts
Nitrile Rubber (NBR)
Advantages: Excellent oil resistance and wear resistance, good elasticity, suitable for high-load transmission environments.
Applications: Widely used in driving generators and water pumps as auxiliary equipment.
Fluoroelastomer (FKM)
Advantages: High-temperature resistance, chemical corrosion resistance, strong oil resistance, suitable for harsh working conditions.
Applications: Used in engine timing systems to ensure stable operation under extreme temperatures.
Polyurethane (PU)
Advantages: Extremely high wear resistance and tear resistance, good elasticity and rebound, reduces vibration and noise.
Applications: Used in heavy-duty operational equipment requiring high wear resistance and high-strength transmission.
Ethylene Propylene Diene Monomer (EPDM)
Advantages: Strong weather resistance and ozone resistance, withstands high and low temperatures, good elasticity.
Applications: Suitable for transmission parts of cooling systems and irrigation equipment.
Summary
Selecting the appropriate type and material of belts for combine harvesters not only enhances transmission efficiency but also extends the equipment’s service life and reduces maintenance costs. By rationally matching different types and materials of belts based on specific working environments and transmission requirements, the high-efficiency and stable operation of combine harvesters can be ensured.
