Classic V-Belts are common power transmission components in mechanical drive systems. The material of the belt directly affects its durability and operational efficiency.
1. Common Materials
• EPDM (Ethylene Propylene Diene Monomer)
EPDM offers excellent heat resistance, aging resistance, and ozone resistance. It is suitable for high-temperature and outdoor environments, effectively preventing rubber aging and extending service life. EPDM also possesses good wear resistance and tear resistance, making it ideal for high-load and complex operating conditions, ensuring long-term operation without deformation.
• Chloroprene Rubber (CR)
Chloroprene rubber is oil-resistant and corrosion-resistant, making it particularly suitable for agricultural machinery and pump equipment. It performs well in environments exposed to oil and chemicals, ensuring stable belt operation.
• Natural Rubber (NR)
Natural rubber provides excellent elasticity and is suitable for light-load equipment. However, its oil and heat resistance are relatively weak, making it mainly used for general-purpose machinery.
2. Reinforcement Layer Materials
• Polyester Cord – Enhances the belt’s tensile strength and prevents stretching and deformation.
• Aramid Fiber – Offers high tensile strength and heat resistance, suitable for high-load equipment.
3. Importance of Choosing the Right Material
Selecting the appropriate material based on the operating environment can improve equipment efficiency, reduce downtime and maintenance costs, and ensure that V-belts operate reliably under complex conditions, enhancing the overall reliability of the equipment.
