How should couplings be maintained?

Synchronous belts are mainly classified into two categories based on the shape of the teeth: trapezoidal teeth and circular arc teeth. Based on the arrangement of the teeth, they can be further divided into single-sided toothed synchronous belts and double-sided toothed synchronous belts. Polyurethane synchronous belts utilize highly wear-resistant polyurethane, which is 3-4 times stronger than black rubber. The core is formed by heat-sealing steel wire or aramid fiber, exhibiting excellent performance in mechanical strength, wear resistance, oil resistance, and weather resistance, possessing unparalleled advantages over black rubber belts. As the next generation of conveyor and transmission belts, polyurethane synchronous belts are widely used in various aspects of industry. Rubber synchronous belts use high-quality imported neoprene rubber as the main raw material, combined with various auxiliary materials for different purposes; the skeleton material is imported high-quality glass fiber rope.
