The V belt of Fig. 1 comprises 2, one the load-carrying layers of being made up of a few circle of load-carrying member 64 of main component that are called compression element in the Prior Art, can discuss in following method step again, and these several circles are right after compression element 2 and are right after each other.Compression element 2 makes by comprising a kind of solid-state but elastomeric material that can soften at least, and this elastomeric material comprises a kind of first elastomer.Load-carrying member 6 comprises a rope 8 that strengthen, high-intensity and embeds in the envelopes 10, and envelope 10 also makes by comprising a kind of solid-state but elastomeric material that can soften at least, and this elastomeric material comprises a kind of second elastomer.This first and this second elastomer can fuse each other, thermoplastic elastomer polyurethane (as the ESTANE of B.F.Goodrich) for example preferably, polyester (as the HYTREL of Du Pont), olefin(e) (as the LEVAFLEX of Bayer) or alloy (as the SANTO-PRENE of Monsanto).
Seeing so-called tension member 12 in addition, is the selectable elements that is connected on the layer 4 of load-carrying member 6.Tension member 12 also is to make by comprising a kind of solid-state but elastomeric material that can soften at least, and this elastomeric material comprises a kind of the 3rd elastomer.The 3rd elastomer can fuse with this second elastomer at least, preferably also is the thermoplastic elastomer of mentioned kind.
Though the tension member 12 among Fig. 1 is smooth and smooth, in the application of for example moving belt, tension member can have non-rectangular cross-section, as the triangular-section, maybe convex-concave surface can be arranged.
With conventional method preformed load-carrying member 6 in the openend spool, a circular cross-section is arranged and comprise one and strengthen rope 8 among Fig. 2, strengthen rope 8 and wrap in securely in the material 10 of above-mentioned definition, material 10 is compatible with the material of the above-mentioned compression element that also defined 2.Rope 8 itself is to be made by Materials with High Strength, for example cotton, artificial silk, polyester or aromatic polyamides (aramid).Before inlaying, strengthen rope 8 and be coated with priming such as water ring oxygen priming paint and sticker such as polyurethanes sticker, but and heat treatment to promote engineering properties.
In some applications, rope 8 can produce by reversing or knit two kinds of materials at least together: a kind of is high strength and another kind of material to envelope 10 has good natural adhesion strength.
The embodiment of Fig. 3 will have the tension member 12 of load-carrying member 6 also to single pre-shape member.
As mentioned above, all belt components: compression element 2, load-carrying member 6 and (selectable) tension member 12 be by conventional method for example extrude, casting or modeling be pre-formed.From these preformed elements, the following step is proposed according to method of the present invention:
A slice compression element 2 is cut into the Len req that is determined by each diameter of pulley and centre distance, a compression element band is provided therefrom, preferably the free end of this sheet is engaged afterwards and form correct joint 14 as Fig. 4.Certain bonding method can select that the material character of the most suitable compression element 2 and instrument prepare for the property used.So,, can make hot plate of two ends contact or blade withstand two ends then and press mutually and engage for thermoplastic material.On the other hand, can use hot-air injection or any known joining technique in conjunction with heating and pressure.
Another selection is to use sticker, and this method is not limited to thermoplastic material and also can be applied to vulcanized rubber, crosslinked polyurethane or the like.
The compression element band also can die casting or method of moulding once make with one step.After the compression element band is made with above-mentioned either party's formula, the load-carrying member 6 of resigning from office by the spool of pre-shape element, be adjacent to each other with continuous spiral mode and every circle, vertically twine top surface 16(Fig. 4 of compression element 2), preferably roughly cover the latter's width.In this coiling, exerting pressure promotes load-carrying member 6 to belt surface 16.This pressure can produce through tension load-carrying member 6 or by at least one dancer (floating roller) when coiling.In the coiling stage, at this load-carrying member and this before the two superficial layer of compression element endless belt contacts with each other for no reason, the two simultaneously and optionally softening.Should softening implement through application of heat and/or sticker.
Application of heat or sticker and pressure make following the two formation intimate engagement (a) between the load-carrying member 6 and belt surface of horizontal, and (b) between a new circle and last circle of load-carrying member.After the application of above-mentioned load-carrying layer 4,, in fact contain from the two molten material of the softener material of the softening superficial layer of rope envelope 10 and belt surface between load-carrying member 6 of this layer and the interface between the belt surface 16.Owing to apply coiling pressure, load-carrying member 6 is partially submerged at least or adds outward in the belt surface 16, the impression 9 of groove shape is high-visible in Fig. 1 and Fig. 6.The load-carrying member should be added to belt surface at least 20%.Be preferably between the adjacent circle and do not have headspace.
Preferably the thickness of the softening superficial layer of load-carrying member 6 is less than the thickness of the envelope 10 of rope 8, thereby can not destroy the adherence between rope and its envelope, and the pre-shape that the thickness of softening superficial layer is preferably in load-carrying member optimization in the stage.Reach this, must highly select and good heat and/or the sticker of regularly applying.
The amount of the pressure of preferably adjusting the amount of heat and/or sticker and applying is to obtain best threading speed.
The other method of generation load-carrying layer 4 is that several load-carrying members 6 wind the line simultaneously, and several load-carrying members 6 produce a plurality of ends and thereby reduce and prepare the driving required time of belt.
Next similarly program is applied to selectable tension member 12, except this member clearly can not be used the helical form, but can be the shape of having only a circle under straight and most of situation.Use member as shown in Figure 3, load-carrying member and tension member only are applied in the step.
The device that cooperates Fig. 5 to 7 representative more can be understood according to method of the present invention, and the task of this device provides has continuously the belt drive unit of load-carrying layer for no reason.Can see by one and form belt or modeling pulley 18(Fig. 5,6), the flank (flank) of its channel profiles coupling compression element 2, this pulley of tool can be by manpower or is preferably rotated through change-speed gearing motor 22.The second running down pulley 24 separates with pulley 18 and aligns with it.Running down pulley 24 is rotatably installed on the piece 26, and piece 26 has internal thread and frame on screw 28, and screw 28 has only one degree of freedom in rotation.Therefore, through handle 30) rotary screw 28, make piece 26 and 24 translational motions of running down pulley, allow the centre distance that changes between pulley 18 and the running down pulley 24.Bar 32 passes the forked projection 34 that adheres to piece 26 and rotates around screw 28 to prevent the latter, allows above-mentioned translational motion simultaneously.Screw 28 and bar 32 are installed between the carriage 33, and obviously, carriage 33 is static for running down pulley 24 and its mounting blocks 26.
See that in addition a guide block 36(also can be referring to Fig. 7), load-carrying member 6 therefrom passes, and draws supply spool 37 in twining the belt way, below can be explained in more detail.
Can see that air blast 44 is fixedly mounted under the guide block 36 or translation separates, the spray hot wind that air blast 44 is produced is by nozzle 46 guiding load-carrying members 6, and it contacts with belt surface by guide block 36.Perhaps, the required heat of engaging process can be provided by concentrated radiant heat source, also can be provided by concentrated ultrasonic vibration source or concentrated electromagnetic viscosimeter source.Yet under the latter's situation, the material of must restrict envelope and/or compression element endless belt comprises little metallic.
By any said procedure production, the compression element 2 of gained is installed on two pulleys, and modeling pulley 18 and running down pulley 24 make pulley separately till compression element endless belt for no reason is quite tight by turning handle 30.The terminal of load-carrying member 6 is drawn the supply spool then, and pass guide block 36(guide block and be set in initial lateral attitude, that is, with respect to the left end of belt) and be attached to belt, for example, point is welded to belt.Now hot-air being sprayed (or each different thermal source) opens; and priming gear motor 22 and make modeling pulley 18 rotation and drive belt 2; use towing by the jet load-carrying member 6 that heats, load-carrying member 6 is engaged to (and softening) belt surface of even heating.When the load-carrying member passed guide block 36, the friction that is provided by the load-carrying member that moves had produced reversal interlocking relay, thereby produced the required tension of neat coiling.Activating pressure is produced by identical reversal interlocking relay, and this reversal interlocking relay is that the deflection of load-carrying member 6 causes when the arcuate part of the belt surface in the load-carrying member 6 contact pulleys 18.As mentioned above, required pressure can simultaneously or be applied by at least one dancer (not shown) in addition.
When belt 2 begins to drag the load-carrying member when mobile, guide screw nail 38 also begins rotation, and guide block 36 is moved right.Therefore, when pulley 18 rotation, that is belt causes that load-carrying member 6 twines belts 2 when moving, and laterally moving of guide block 36 produces spiral path thereby produce neat load-carrying layer 4.
Required relation between the linear speed of the rotary speed of pulley 18 and guide block 36, having more than is width and the diameter of load-carrying member 6 or the function of width of belt 2, or the function of the superficial velocity of belt.This is the importance of control element 42.
When another configuration is finished at each circle of compression element 2, need the stepwise operation of guide block 36.
The reinforcement belt that is applied to selectable tension member 12 is also followed similar design, and except the different guide block of needs, and this guide block can laterally not move, and fixedly aligns and is with 2.Spray though nozzle 46 produces the hot-air that is rather narrow, quite wide elastic component needs a wide and flat injection (perhaps the multi-stylus head sprays).
Use has the device of sticker, can replace air blast combination 44,46 by a sticker dispenser (dispenser).But this dispenser is thermal source of affix certainly.
The invention describes a common V belt though embodiment is shown, but must understand that the method and apparatus of being discussed also is applicable to the driving belt of producing other type, as inserted (coggde) V belt, flat belt and synchronous or positive motion belt (timing belt).
The people who has the knack of this skill must know that the present invention is not limited to the details of the foregoing description, and the present invention can specialize in other specific forms and not depart from its spirit or critical nature.For example, first step can be spirally wound on the load-carrying member at least one installation pulley with a general planar outer surface, use to form and contain most circles but at least greater than one deck of a whole circle, second step is put in order circle in the outer surface winding of this layer of this load-carrying member with lucky one of pre-shape openend compression element profile, uses and makes this compression element profile this surface of this circle of this wire winding layer of this load-carrying member of fluid-tight engagement in the above described manner simultaneously.Therefore, with regard to each side, present embodiment should be considered as the explanation and unrestricted.Therefore, the institute in claim changes all to regard and comprises wherein.
