A flexible toughening layer is arranged between the compressive layer and the wrapping cloth. Compared with the prior art, the fatigue-resistant narrow V-shaped belt has the advantages that the flexible toughening layer is additionally arranged on a belt body, the thickness of the flexible toughening layer is small, the longitudinal flexibility of the flexible toughening layer is better than that of the compressive layer, the flex-resistant performance and anti-aging performance are improved, aramid fiber is added in rubber of a base body, and the transverse rigidity of the belt body is improved; further, the binding power between the flexible toughening layer and the wrapping cloth is larger than that between the compressive layer and the wrapping cloth, reduction of the internal stress of the belt body is facilitated, the belt body is good in extensibility, and the transferring process of the belt body is smooth.
Description
Technical field
The utility model relates to a kind of V band, relates in particular to a kind of endurance narrow V belt.
Background technique
The V-type adhesive tape is called for short V band or vee belt, is that cross section is the general designation of the annular driving band of isosceles trapezoid or approximate isosceles trapezoid, and its working surface is bi-side, and the angle of bi-side is the angle of wedge.Compare with flat transmission belt, the characteristics such as V band has simple installation, floor space is little, and transmission efficiency is high, noise is little are occupied critical role in whole transmission field.
The V band can divide extraordinary belt carcass V band and classical V-belt two large classes, can be divided into classical V-belt, narrow V belt, wide V band, poly Vbelt etc. by its shape of cross section and size; Can be divided into type V-belt cloth wrapping and merit limit formula V band by girdle structure; Can be divided into cord core V belt and rope core v belt by the band cored structure.
Domestic narrow V belt is general to adopt natural/butylbenzene/butadiene rubber, because the phenomenons such as premature ageing, be full of cracks often appear in non-refractory, working life is short.To the improving constantly of narrow V belt power character and environmental requirement, the structure of power transmission design is more and more compacter along with in recent years, and the load that the narrow V belt belt body bears is increasing, and the temperature that belt body bears is more and more higher, and the narrow V belt of traditional material has not met usage requirement.Neoprene (CR) has excellent resistance to high temperature, thereby becomes the first-selected material of main part that substitutes natural rubber.
Be that the Chinese patent literature of CN1065711A discloses a kind of Noninflammable static electricity conducting narrow V belt semi-product such as notification number, it is comprised of infantees layer, compression layer, layer of fibers, buffer layer, strength layer and stretchable layer, it utilizes neoprene to replace most natural rubber, and flame retarding and anti-static electricity property are good.
Existing product is in order to improve the lateral stiffness of narrow V belt, and thickness of compressed layer is often larger, and the belt body longitudinal flexible is not enough, and flexural stress is larger when causing turning round, and is prone to the phenomenons such as primer cracking, and fatigue life is shorter.
The model utility content
The utility model provides a kind of endurance narrow V belt, and is not enough to solve existing narrow V belt longitudinal flexible, the problem that fatigue performance is poor.
A kind of endurance narrow V belt comprises inner core and infantees, and described inner core comprises upholds layer, strength layer, buffer layer and compression layer, and flexible toughening layer is arranged between described compression layer and the infantees.
The base rubber of described flexible toughening layer is preferably neoprene, and has added aramid fiber in base rubber, when guaranteeing the belt body lateral stiffness, has improved longitudinal flexible and the warping strength aging quality of belt body.
For guaranteeing the longitudinal flexible of belt body, preferably, the thickness of described flexible toughening layer is 0.1～0.5mm.
More preferably, the thickness of described flexible toughening layer is 0.1～0.3mm.
Further preferably, the thickness of described flexible toughening layer is 0.18～0.22mm.
Most preferably, the thickness of described flexible toughening layer is 0.2mm.
If flexible toughening layer is too thick, not only flexible meeting reduces, and because aramid fiber is expensive, can increase the fabricating cost of belt body.
In order to improve the tensile strength of belt body, as preferably, also has fiber-reinforced layer between buffer layer and the compression layer.In the utility model, the base rubber that fiber-reinforced layer adopts is neoprene, and has added cotton powder and rubber bond RC in base rubber, has significantly improved the tensile strength of belt body.
In the utility model, in strength layer, also be embedded with the cotton rope of vertical layout, further improved the tensile strength of belt body.
As preferably, described infantees is made of the flexible Wide-angle cloth of 3-5 layer 120 degree.The flexible Wide-angle cloth of 120 degree can use in the high temperature transmission system for a long time.
Compared with prior art, the beneficial effects of the utility model are:
The utility model belt body has increased flexible toughening layer, and flexible toughening layer thickness is less, and longitudinal flexible is better than compression layer, and the anti-aging quality of subduing strengthens, and has added aramid fiber in base rubber, has improved the lateral stiffness of belt body; Cohesive force between flexible toughening layer and the infantees helps to reduce the belt body internal stress greater than the cohesive force between compression layer and the infantees in addition, and belt body is more unfolded, and is more smooth and easy in the operation process.
Description of drawings
Fig. 1 is the cross-sectional configuration schematic representation of the utility model endurance narrow V belt.
Embodiment
As shown in Figure 1, a kind of endurance narrow V belt, the angle of wedge are 40 °, are made of infantees 10 and inner core 20, infantees 10 is made of the flexible Wide-angle cloth of 3-5 layer 120 degree, and inner core 20 forms by upholding layer 21, strength layer 22, buffer layer 23, fiber-reinforced layer 24, compression layer 25 and flexible toughening layer 26.
Traditional narrow V belt generally only is comprised of extension layer, strength layer, buffer layer, compression layer.The utility model has increased fiber-reinforced layer 24 and flexible toughening layer 26 on the basis of existing technology, that is to say existing compression layer is divided into three layers.Wherein the base rubber of fiber-reinforced layer 24 employings is neoprene, and has added cotton powder and rubber bond RC in neoprene, can significantly improve the tensile strength of belt body.
The design of the utility model most critical is that compression layer 25 surfaces are covered with flexible toughening layer 26, and the base rubber of flexible toughening layer 26 also is neoprene, and has added aramid fiber in neoprene.In this embodiment, the thickness of flexible toughening layer 26 is 0.2mm.Flexible toughening layer 26 has not only guaranteed the lateral stiffness of belt body, and has improved longitudinal flexible and the warping strength aging quality of belt body.When the Accidental occurrences such as pinch roller inclination, if infantees 10 wearing and tearing, more than the narrow V belt endure 500km of the present utility model.
It is identical upholding layer 21, strength layer 22 and the rubber compounding that buffer layer 23 adopts, and can adopt existing conventional formulation.Be embedded with the cotton rope 27 of vertical layout in the strength layer 22.In this embodiment, fiber thread rope 27 adopts the two sth. made by twisting of 3*5Z/S to bifilar winding displacement, guarantees tension stability, and winding displacement is even, to improve the tensile strength of belt body.
