Abstract
The utility model discloses a kind of driving belt, the core-wire layer comprising gum layer, primer layer and be arranged between gum layer and primer layer, is provided with many heart yearns in described core-wire layer, and described many heart yearns comprise left-hand lay alternately to heart yearn and right-laid to heart yearn.Therefore, can driving belt be prevented by rationally arranging heart yearn, particularly poly Vbelt and V-type band generation twisting wrapping phenomena, in use, also deviation phenomenon can not occur simultaneously.
Description
Technical field
The utility model relates to a kind of driving belt.
Background technique
Driving belt is the power motor of prime mover or engine revolution produced, and is transmitted in machinery, therefore is referred to as again powered belt or belt by belt wheel by adhesive tape, it is the core coupling component of electromechanical equipment, purposes is very extensive, and kind is abnormal various, has the kinds such as such as poly Vbelt and V band.In the prior art, the heart yearn of most of driving belt is all adopt unidirectional rotation direction, so the driving belt just causing single rotation direction heart yearn is being made and after placing a period of time, easily twisting phenomenon occurring.Studying carefully its main cause is manufacture in the operation of driving belt, need to be wound around heart yearn on rubber sleeve, heart yearn is subject to tensile force when being wound around, after gum cover and belt are made, tensile force suffered by heart yearn can produce the stress of torsion on heart yearn, and this stress can act in line belt further, therefore, after a period of time placed by driving belt, can there is twisting wrapping phenomena in it under the effect of this stress.If the driving belt of long size, and when belt body is more soft again, twisting wrapping phenomena can be more obvious, and the subsequent installation that have a strong impact on client uses.
In addition, in driving belt using process, pulling force suffered by it can conduct to heart yearn, this pulling force can because heart yearn sth. made by twisting to and be decomposed into horizontal and vertical two power, transverse component wherein can make transmission with the trend of transverse movement, if the heart yearn in driving belt adopts unidirectional rotation direction, driving belt sideslip in transmission process can be caused.
Model utility content
The purpose of this utility model is, for above-mentioned defect of the prior art, to provide a kind of driving belt.
For realizing above-mentioned model utility object, the utility model have employed following technological scheme: a kind of driving belt, the core-wire layer comprising gum layer, primer layer and be arranged between gum layer and primer layer, be provided with many heart yearns in described core-wire layer, it is characterized in that: described many heart yearns comprise left-hand lay alternately to heart yearn and right-laid to heart yearn.
In addition, the utility model also provides following attached technological scheme:
The arranging density of described many heart yearns is even.
Described many heart yearns are made up of glass fibre.
The inner integrated stress of described driving belt is roughly zero.
Described right-laid has the first transverse component to heart yearn, and described right-laid has the second transverse component to heart yearn, and this first and second transverse component is cancelled out each other.
Described driving belt is poly Vbelt.
Described driving belt is V-type band.
Compared to prior art, advantage of the present utility model is: disclose a kind of driving belt, many heart yearns in this driving belt core-wire layer be left-hand lay to right-laid to alternately, therefore, after by the way rationally heart yearn being set, driving belt generation twisting wrapping phenomena can be prevented, and in use, also deviation phenomenon can not occur.
Accompanying drawing explanation
Fig. 1 is the poly Vbelt schematic diagram corresponding to the utility model preferred embodiment.
Fig. 2 corresponds to the left-hand lay of the utility model preferred embodiment to heart yearn schematic diagram.
Fig. 3 corresponds to the right-laid of the utility model preferred embodiment to heart yearn schematic diagram.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
A kind of driving belt, comprises the type such as poly Vbelt and V-type band, and is mainly used on the power transmission of automobile.Can be clear that by Fig. 1, the type of this driving belt is poly Vbelt, its core-wire layer 3 mainly comprising gum layer 1, primer layer 2 and be arranged between gum layer 1 and primer layer 2, many heart yearns 4 are provided with in this core-wire layer 3, these heart yearns 4 for left-hand lay to right-laid to alternately, and arranging density is even.
The material of main part of above-mentioned poly Vbelt can comprise the material of any one making drivign belt that this specialty is understood, and these materials comprise natural rubber, synthetic rubber and special synthetic rubber etc.Due to the utility model for be poly Vbelt, therefore primer layer 2 contains the profile of any one poly Vbelt that this specialty is understood, and comprises flute profile.Many heart yearns 4 are smooth in an orderly manner, be laid in core-wire layer 3 even density, as shown in Figures 2 and 3, these heart yearns 4 comprise left-hand lay to heart yearn 4s and right-laid to heart yearn 4z, this left and right sth. made by twisting is all equal with the twist to the size of heart yearn 4s, 4z, and be spacedly arranged in core-wire layer 3, arrangement pitches is equal.Can learn further combined with Fig. 2 and Fig. 3 again, left-hand lay has the first transverse component a to heart yearn 4s, right-laid has the second transverse component b to heart yearn 4z, this is first years old, two transverse component a, b equal and opposite in direction, direction is contrary, therefore when these heart yearns 4 according to said sequence alternately on core-wire layer 3 time, namely this poly Vbelt these heart yearns 4 according to right-laid to left-hand lay to time alternately, the transverse component of these heart yearns 4 can be cancelled out each other, the inside integrated stress of poly Vbelt is made to be roughly zero, this poly Vbelt is prevented to make and twisting wrapping phenomena occurring after placing a period of time, in use, the left-hand lay of this poly Vbelt also can be cancelled out each other to heart yearn 4s and right-laid to the transverse component suffered by heart yearn 4z, thus prevents poly Vbelt sideslip simultaneously.
Technique scheme can also be applied on V-type band, and wherein the primer layer of V-type band contains the profile of any one V-type band that this specialty is understood, and comprises trigonometric form.The key elements such as the material of the heart yearn 4 of V-type band and arrangement mode are all consistent with the technological scheme of above-mentioned announcement, thus also prevent V-type band and making and twisting wrapping phenomena occurring after placing a period of time, and in use, also can not there is deviation phenomenon in V-type band.
It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
