AI Technical Summary
Traditional fabric-covered V-belts have drawbacks in the agricultural machinery returning field machine market, such as high elongation, narrow temperature range, and large bending radius, which cannot meet the needs.
The toothed V-belt, made of EPDM rubber, consists of an EPDM rubber top layer, a skeleton layer, and a scraped canvas layer. The skeleton layer is composed of polyester or aramid cords. The tooth design improves strength and heat dissipation, making it suitable for complex pulley systems and allowing for installation on smaller pulleys.
It improves the fatigue resistance and heat dissipation performance of V-belts, making them suitable for complex pulley systems. It also enhances the adaptability of installation on small pulleys and meets the temperature and wear resistance requirements of troweling machines.
