Components Of The V-belt

  • The components of the triangular belts are as follows:

    Ordinary rubber V-belts are generally composed of wrapping layer, stretch layer (top rubber), strength layer (tensile layer) and compression layer (base rubber).

    The functions of the different parts are as follows:

    1. The wrapping layer, the wrapping layer is composed of plain weave canvas (mainly cotton canvas and polyester-cotton canvas) diagonally cut at 45°, with excellent elasticity and friction, can connect various parts to become a whole, and protect others Part is not subject to wear and erosion, and can increase the stiffness of the V-belt.
    2. The stretch rubber layer, which is composed of a rubber material with high elasticity and excellent stretch performance, can withstand the tensile stress of the V-belt when it is running and bend, and play a buffer protection role for the strong layer.
    3. The strong layer, the strong layer is the skeleton of the V-belt, the main types are polyester cord, polyester tempered brown wire, aramid cord and dipped cord fabric, etc., which are used to withstand the production of the V-belt during operation The tensile stress is the main stress part in the V-belt transmission process.
    4. Cushioning rubber, polyester tempered brown ribbon core or V-belt with cord core around the strength layer, there is a layer of rubber with good adhesion strength with the core, which is the cushioning rubber, which acts as a fixing belt The role of the core, and can absorb the dynamic shear stress generated by the frequent deformation of the V-belt during high-speed operation.
    5. Compression rubber layer. Compression rubber layer is composed of rubber material with excellent bending fatigue resistance. It can bear the compression stress generated by the V-belt during operation and bending, maintain the rigidity and elasticity of the V-belt, and increase the section of the V-belt. And the friction contact surface with the pulley, improving the transmission efficiency.

    Due to the different functions of different parts, the rubber formula used is also different

    The same is true for the composition of the hexagonal belts.
