Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but As long as all being protected by Patent Law in the right of the utility model.

As illustrated in fig. 1 and 2, a kind of V-belt, including triangle band body 1 and the infantees that is wrapped in outside triangle band body 1 Layer 2.

As shown in Fig. 2, triangle band body 1 is the structure of annular, the section of triangle band body 1 is trapezoidal, triangle band body 1 Face where small head end is the inner surface of triangle band body 1, and the face where 1 stub end of triangle band body is triangle band body 1 Outer surface.Triangle band body 1 includes from inside to outside compression layer 11 successively, strength layer 12, upholds glue-line 13.

Compression layer 11 bears V-belt generated compression stress when operating bending, to keep the rigidity and bullet of V-belt Property.The material of compression layer 11 is neoprene, and neoprene is a kind of compound of synthetic rubber, and neoprene has anti-flammable good, resistance to The advantages that aging is good, durability is good, and neoprene has preferable cementability.

Strength layer 12 is the skeleton of V-belt, and effect is subject to V-belt, and generated stretching etc. is answered during the motion Power is the main part of the force during V -- belt Drive.If strength layer 12 includes several polyester cords 121 and is used to incite somebody to action The cushion gum layer 122 that dry polyester cord 121 bonds together.Polyester cord 121 includes more root ropes 1211, more root ropes 1211 It is mutually wound polyester cord 121 in the shape of a spiral, compared to single polyester cord 121, the polyester cord 121 of the structure is gathered around There is higher intensity.It is equipped with polyester cord 121 in triangle band body 1, on the one hand improves the tensile strength of this V-belt, this V-belt is not easy to break；On the other hand since polyester cord 121 possesses certain elasticity, this V-belt can be reliably stretched in On belt pulley.The material of cushion gum layer 122 is neoprene, and neoprene has preferable cementability, and polyester cord 121 has The good advantage with rubber adhesion, then the strength layer 12 formed by polyester cord 121 and neoprene is more compact in structure, whole Body is preferable.In addition the material of compression layer 11 is also neoprene, then compression layer 11 can preferably be bonded in one with strength layer 12 It rises, improves the globality of triangle band body 1.

It upholds glue-line 13 and bears tensile stress of the V-belt when operating bending, and buffer protection is played to strength layer 12 and is made With.The material for upholding glue-line 13 is also neoprene, and the glue-line of neoprene is flexible, and preferably, impact resistance and vibration improve three to elasticity The service life of angle band, and uphold glue-line 13 and can preferably be bonded together with strength layer 12, improve triangle band body 1 Globality.

As shown in figure 3, the circumferentially-spaced of 1 upper edge triangle band body 1 of triangle band body offers several grooves 3, groove 3 Rectangular cross-section is embedded with steel loop 4 in several grooves 3, and shape, size and the groove 3 of steel loop 4 match, and steel loop 4 and groove Coordinate closely between 3, on the other hand triangle ontology banding can be increased the resistance to of V-belt by 4 one side of steel loop of setting Pressure energy power, and steel loop 4 is that interval is arranged, and is influenced on the bending property of V-belt smaller.

As shown in Fig. 2, infantees layer 2 is wrapped in outside triangle band body 1, protection triangle band body 1 is not easy frayed, erosion, And the stiffness of V-belt can be increased.The material of infantees layer 2 is canvas, and canvas is a kind of cotton fabric or linen of thicker thickness, It is and durable with good water resistance, increases the service life of V-belt.

As shown in Figure 1, offering several heat emission holes 5 on infantees layer 2, heat emission hole 5 is opened along the thickness direction of triangle band body 1 If heat emission hole 5 is round and runs through infantees layer 2 and triangle band body 1.Friction is generated between V-belt and belt pulley in work And generate heat, the heat then generated can be distributed by heat emission hole 5, be conducive to the heat dissipation effect for promoting V-belt, be extended The service life of V-belt.

The above is only the exemplary embodiment of the utility model, the protection model rather than limited the present invention It encloses, the scope of protection of the utility model is determined by the attached claims.
