Abstract
The utility model relates to a rope core V belt which comprises a cloth wrapping layer arranged at the outermost layer; a stretching layer, a strong force layer and a compression layer are arranged in the cloth wrapping layer; the compression layer is arranged between the stretching layer and the strong force layer; the rope core V belt also comprises a transverse rigid layer; the transverse rigid layer is arranged between the strong force layer and the compression layer; and the transverse rigid layer is internally provided with polyester staple fiber. According to the rope core V belt, the transverse rigid layer is added based on the original basis, and the transverse rigid layer has higher transverse rigidity, better longitudinal flexibility and moderate hardness, so that the service performance and the service life of the rope core V belt are effectively improved, and the transmission efficiency is improved.
Description
Technical field
The utility model relates to a kind of V band, and is especially a kind of for mechanically operated rope core v belt.
Background technique
The V band is a kind of line belt that is widely used in the various mechanical transmission, and V band drive mechanism is simple, has overload protection, buffering absorbing, is suitable for advantages such as remote transmission, is widely used in actual production.At present, V band is divided into cord V band and cord knot V is with two kinds.Cord V band belt carcass is the multilayer overlapping, in transmission process, easily relatively moves between the belt carcass hangings lay, causes living heat too much to cause getting up early to be lost efficacy.Rope V belt is the most a kind of V band of present usefulness, and its belt carcass is the monolayer alignment formula, has avoided the problem that relatively moves between hangings lay.But the raising along with rotating speed and transmission power, rope V belt is had higher requirement, rope V belt mainly bears tensile stress and flexural stress at work, under the stretching of alternation and crooked stress effect, fatigue fracture takes place in rope V belt strength layer dual-side portion cotton rope easily, occur the part come unstuck and begin the diffusion, break apart at the ravelled spot that comes unstuck at last, fatigue ruption takes place, and causes the usability of V band and working life to be reduced.
The model utility content
The utility model purpose be provide in order to overcome the deficiencies in the prior art that a kind of usability is good, long service life and the high rope core v belt of transmission efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of rope core v belt, comprise outermost infantees layer, and be provided with in the described infantees layer and uphold layer, strength layer and compression layer, described compression layer also comprises the lateral stiffness layer upholding between layer and the strength layer; Described lateral stiffness layer is between strength layer and compression layer.
Preferably, be provided with polyester staple fiber in the described lateral stiffness layer.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
A kind of rope core v belt of the utility model scheme, set up the lateral stiffness layer on original basis, the lateral stiffness layer has higher lateral stiffness, longitudinal compliance and moderate hardness preferably, thereby can effectively raise usability and the working life of rope core v belt, improve transmission efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of rope core v belt of the present utility model;
Wherein: 1, infantees layer; 2, uphold layer; 3, strength layer; 4, compression layer; 5, lateral stiffness layer.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of rope core v belt as shown in Figure 1 comprises outermost infantees layer 1, is provided with in the described infantees layer 1 to uphold layer 2, strength layer 3 and compression layer 4, and described compression layer 4 also comprises lateral stiffness layer 5 upholding between layer 2 and the strength layer 3; Described lateral stiffness layer 5 is between strength layer 3 and compression layer 4; Be provided with polyester staple fiber in the described lateral stiffness layer 5.
Rope core v belt of the present utility model, set up lateral stiffness layer 5 on original basis, be provided with polyester staple fiber in the lateral stiffness layer 5, such lateral stiffness layer 5 has higher lateral stiffness, longitudinal compliance and moderate hardness preferably, improved the stressed uniformity of rope core v belt strength layer 3 cotton ropes effectively, cross-section area distortion when making rope core v belt work in race is little, increase with the effective area of contact in race both sides, and then make the frictional force between rope core v belt and race also bigger, therefore the moment of torsion of rope core v belt transmission is bigger, has improved the transmission efficiency height; Next changes strength layer 3 cotton ropes of rope core v belt accepts evenly, has effectively reduced the destruction that rope core v belt is excessive because of dual-side portion cotton rope tensile stress and belt body skids and weares and teares and cause, and has improved usability and working life.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
Claims (2)
1. a rope core v belt comprises outermost infantees layer, is provided with in the described infantees layer to uphold layer, strength layer and compression layer, and described compression layer is characterized in that: also comprise the lateral stiffness layer upholding between layer and the strength layer; Described lateral stiffness layer is between strength layer and compression layer.
2. rope core v belt according to claim 1 is characterized in that: be provided with polyester staple fiber in the described lateral stiffness layer.
