Reinforced V belt

Abstract

The invention discloses a reinforced V belt. The reinforced V belt comprises a glue coating fiber fabric layer, a tensile body core wire layer, a bonding glue layer and a compression glue layer; the bonding glue layer is filled in the tensile body core wire layer; and hardened tire fabrics are respectively arranged between the tensile body core wire layer and the glue coating fiber fabric layer and between the tensile body core wire layer and the compression glue layer. compared with the prior art, the hardened tire fabrics with a certain stiffness are respectively arranged on the tensile bodycore wire layer up and down, so that the transverse rigidity of the V belt is greatly improved, the deformation of the belt is reduced, the fatigue resistance is improved, the transfer power is increased, the stress centralization problem of the compression glue layer is prevented, the transmission stability and the reliability are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of drive belt power transmission, in particular to an enhanced V-belt. Background technique [0002] At present, V-belts have been widely used in various fields such as industrial machinery and equipment, buses, and agricultural machinery. However, as the power of these mechanical transmissions continues to increase and the conditions of use become more and more harsh, as well as the service life and reliability of the transmission components of mechanical equipment increase, the performance requirements for V-belts are also getting higher and higher. When used under high power, high tension is often required. When the tension force of the V-belt is greater, the lateral deformation of the V-belt will be greater, so that the middle of the transverse section of the belt will be concave, that is, the transverse direction of the V-belt. The wire ropes of the cross-section tensile body are arranged to be concave...

Problems solved by technology

[0003] Chinese patent CN200520006223.5 proposes a reinforced automobile V-belt, which is provided with polyester, etc. between the core rope layer (also called tensile body) and the fiber fabric layer or / and between the core rope layer and the primer The reinforcement layer of the material, but it does not provide the structure and form of the polyester to form the reinforcement layer, and the reinforcement layer is added to improve the fatigue resistance and tensile strength of the V-belt, and it is difficult to solve the lateral deformation of the belt body under large tension question

Although the V-belts of these two structures can improve the lateral rigidity, the tooth rubber layer or the bottom rubber layer is subjected to high shear stress during operation, the stress is easy to concentrate, and the belt body is easily damaged.

In addition, since the above-mentioned horizontally arranged cords or reinforcing strips are not integrated, they are easily debonded due to mutual friction during use.
