timing belt material

The structural design of a wrapped V-belt typically consists of several key layers. At the core, there is a strong tensile cord made from materials like polyester or nylon, which provides excellent strength and resistance to stretching. Surrounding this core is a rubber compound that enhances flexibility and grip. The outer layer often consists of fabric or additional rubber for protection against wear and environmental conditions. The outer wrap also plays a vital role in providing traction and reducing slippage, which is crucial for effective power transmission.

Cogged belts are typically constructed from flexible materials such as rubber or thermoplastic elastomers, often reinforced with fibers like fiberglass or polyester to enhance their strength and durability. The notches in the belt serve multiple functions they reduce the belt's bending radius, decrease weight, and provide a larger surface area for grip. The precise tooth spacing and design are engineered to ensure that the belt remains engaged with the pulleys throughout its rotation, even under varying loads.
