The high-efficient production technology of V-belt
Technical field
The invention belongs to V-belt technical field, refer in particular to a kind of high-efficient production technology of V-belt.
Background technology
The V-belt of common quality of rubber materials is generally made up of parts such as infantees layer, stretching glue-line (top glue), cord ply (tensile layer) and compression layers (primer).Infantees layer is made up of plain weave rubberized canvas (mainly cotton canvas and polyester-cotton blend canvas), there is excellent flexible and frictional property, various piece can be connected and become overall, protect that other parts are not frayed, etch, and the effect of the stiffness of V band can be increased; It is higher by elasticity for upholding glue-line, and has the sizing material composition of excellent extension performance, bears the tensile stress of V band when operating bending, and plays buffer protection function to strength layer; Cord ply is the skeleton of V band, and kind main at present has polyester cord, polyester tempering monofilament, aramid cord and dipped type cord fabric etc., and effect bears V to be with the stretching iso-stress produced in operation process, is the main part of the force in V--belt Drive process; Cushion gum layer: the V-belt of polyester tempering monofilament belt carcass or cotton rope belt carcass is around strength layer, one deck is had to have the fetters of good adhesion intensity with belt carcass, be buffering adhesive, it plays the effect of fixing belt carcass, and can absorb the V-belt dynamic shearing stress that frequent deformation produces when running up; Compression layer can be made up of by excellent sizing material bending fatigue resistance, bear V-belt and rerun the compression stress that bending thing produces, keep rigidity and the elasticity of V-belt, and play increase cross section, V-belt and the frictional contact surface with belt wheel, improve the effect of transmission efficiency.
At present, although the production technology making V-belt has many kinds, its weak point is: complex manufacturing, and production efficiency ground, unstable product quality, production cost is high.
