Polyurethane timing belts have the following significant advantages over rubber timing belts:Wear resistance and tear resistance: Polyurethane timing belts have excellent wear resistance and tear resistance, especially under high load and frequent use, their surface wear is slower and their service life is longer. Although rubber timing belts also have certain wear resistance, their wear resistance and tear resistance are weaker in comparison, and they are prone to wear and breakage.Oil resistance and chemical corrosion resistance: Polyurethane timing belts are highly oil-proof, grease-proof, and resistant to most acid and alkali corrosion, and are suitable for use in chemical or oily environments. Rubber timing belts have weak resistance to oils and chemicals and are easily corroded by these substances, resulting in material aging or performance degradation.Transmission accuracy and stability: Polyurethane timing belts have high transmission accuracy and stability, which can ensure the accurate operation of the transmission system. Its elastic modulus is high, the energy loss during transmission is small, and the transmission efficiency is high, generally up to 98%-99%. Due to the low elastic modulus of the material, rubber synchronous belts are prone to large deformation during the transmission process, affecting the transmission accuracy and stability, and the transmission efficiency is relatively low.Operating temperature range: The operating temperature range of polyurethane synchronous belts is relatively wide, generally working between -30℃ and +80℃, and can withstand up to +110℃ for a short time. However, the temperature resistance of rubber synchronous belts is poor, especially in high temperature environments, they are prone to aging, hardening and embrittlement, affecting their durability.
Low noise and low vibration: Polyurethane synchronous belts have low noise and low vibration during the transmission process, providing a quieter and smoother operating environment for mechanical equipment. Although rubber synchronous belts also have a certain degree of quietness, their noise and vibration levels may be slightly higher in comparison.Special processing and customization capabilities: Polyurethane synchronous belts can undergo a variety of special processing, such as adding cloth to the tooth surface, backing glue, adding blocks, etc., to meet different application requirements. Although rubber synchronous belts can also undergo some processing, they are relatively weak in special processing and customization capabilities.
