The invention discloses a low-noise V-ribbed belt. Comprises a top layer, a tensile body core wire, a bonding layer, a wedge glue layer, hollow fibers and a reinforcing fabric; the wedge glue layer is located the bond line below, is provided with wedge portion on the wedge glue layer, and the hollow fiber of evenly transversely arranging in the wedge portion, it has the tensile body heart yearn to inlay in the bond line, the top level is located the bond line top, be provided with the reinforcement fabric in the top layer. The hollow fiber has good buffering deformation energy consumption effect and good damping property, and can effectively improve the bending stress and stress deformability of the wedge adhesive layer in the operation process, so that the wedge surface is better attached to the belt wheel, the contact area is increased, the friction force in unit area is increased, the transmission efficiency is improved, and the slip rate and the noise generation amount are reduced. Meanwhile, the hollow structure of the hollow fiber can effectively absorb and scatter noise, and the outward conduction proportion of the noise generated by the belt and the belt wheel is reduced, so that the external perception of the noise is reduced. |
