Description

Noise-reducing and energy-saving rubber V-ribbed belt

Technical Field

The utility model relates to an EPT rubber V-ribbed belt, in particular to energy-saving rubber V-ribbed belt of making an uproar falls.

Background

The V-ribbed belt as a transmission belt is widely applied to the fields of engines, electric appliances, compressors and the like by virtue of the advantages of small transmission vibration, quick heat dissipation, stable operation, small use elongation, high limit linear speed and the like.

During the use of the v-ribbed belts, a number of problems have been raised and appreciated, such as: how to improve the transmission efficiency of the V-ribbed belt, reduce the wear rate of the V-ribbed belt, reduce the noise in use and the like; when the V-shaped belt is used, the V-shaped belt is sleeved on the pulleys on the driving side and the driven side, the contact area between the V-shaped belt and the pulleys is large, the friction force between the V-shaped belt and the pulleys is large, and higher power can be transmitted compared with the V-shaped belt.

Chinese patent CN200880024509 discloses a v-ribbed belt having a wedge forming surface with a plurality of wedges extending in the longitudinal direction of the belt, the wedge forming surface having a recessed portion for allowing water to flow in and reducing the noise generated by the v-ribbed belt when wetted, but the v-ribbed belt has a complex structure, and the presence of the recessed portion reduces the contact area between the v-ribbed belt and the belt wheel, which is not suitable for transmitting large power and has a not wide application range.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned not enough that exists among the prior art, the utility model provides an energy-saving rubber polywedge bet of making an uproar falls, it not only has long service life and nontoxic pollution-free characteristics, still has the advantage that the noise in the use is low.

The technical proposal of the utility model for solving the technical problem is that: the noise-reducing and energy-saving rubber multi-wedge belt comprises a belt body made of rubber, wherein a group of trapezoidal wedges are arranged on the inner side of the belt body; a canvas layer adhered to the belt body through vulcanization is arranged on the outer side of the belt body, and the laying direction of the canvas layer is parallel to the transmission direction of the V-ribbed belt; a framework formed by winding framework rope groups in parallel along the transmission direction of the V-ribbed belt is arranged inside the belt body, and each framework rope group is formed by an aramid fiber wire and a hollow fiber wire which are closely arranged side by side; the diameter of the aramid fiber wire is 0.7-0.9 mm, the diameter of the hollow fiber wire is 0.5-0.8 mm, and the winding density of the framework rope group is 3-5 groups/cm.

Compared with the prior art, the utility model discloses an energy-saving rubber polywedge bet of making an uproar falls has following progress:

a skeleton rope group formed by combining aramid fiber lines and hollow fiber lines is arranged inside the belt body and wound side by side along the transmission direction of the V-ribbed belt to form a skeleton; the rope group under the specific wire diameter and the winding density can convert the sound energy generated by the V-ribbed belt during the work into heat energy to be dissipated, thereby reducing the noise generated by the V-ribbed belt during the use; the phenomenon that the thread rope is broken due to stress concentration caused by improper spacing in the use process can be reduced; the tensile strength of the trapezoidal wedge is improved, the tear resistance is enhanced, and the phenomenon of cracks in the belt body is reduced, so that the service life of the product is prolonged, and the use cost of a user is reduced.

As the optimization of the noise-reducing and energy-saving rubber V-ribbed belt, the diameter of the aramid fiber wire is 0.8mm, the diameter of the hollow fiber wire is 0.6mm, and the winding density of the skeleton rope group is 4 groups/cm. The inventor finds that the noise generated by the wedge belt in use can be relatively better reduced. Furthermore, the hollow fiber thread is made of terylene. The hollow fiber thread made of the terylene material can increase the adhesiveness between the hollow fiber thread and the V-ribbed belt of the utility model, and reduce the separation of the contact part of rubber and thread rope; and the fiber thread is easy to obtain and is suitable for large-scale production.

As the optimization of the noise-reducing and energy-saving rubber V-ribbed belt, the Shore hardness A of the belt body made of the rubber material is 55-85 degrees. The rubber with the hardness range can be better suitable for the V-ribbed belt, and reduces the abrasion of the V-ribbed belt body in use. Further, the belt body is made of ethylene propylene diene monomer. The material of the belt body is non-polar ethylene propylene diene monomer, which is friendly to human body and environment and has resistance to polar solution and chemicals, so that the water absorption rate is low and the corrosion resistance is good, and the V-ribbed belt has good capability of resisting heat, water, acid, alkali, light and oxygen; and the ethylene propylene diene monomer rubber has excellent low-density and high-filling property, so that the multi-wedge belt has the characteristic of low production cost.

As an optimization of the noise-reducing and energy-saving rubber V-ribbed belt, a printing area is arranged on the surface of the canvas layer. It is convenient to print various marks.
