Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a flexible joint and a manufacturing apparatus therefor, and more particularly to a method for manufacturing a flexible joint for connecting a drive shaft and a driven shaft suitable for a power transmission system of an automobile and a manufacturing apparatus therefor. Regarding

[0002]

2. Description of the Related Art A conventional flexible joint of this type is disclosed in, for example, Japanese Utility Model Laid-Open No. 59-146623. In this conventional example, a cylindrical body connected to the drive shaft side and a cylindrical body connected to the driven shaft side are arranged at equal positions in the circumferential direction, and special processing is performed between the adjacent cylindrical bodies. The formed fiber cord is wound around a plurality of times, and a rubber paste is applied to the fiber cord and vulcanized and cured. Furthermore, by providing an intermediate flange on the tubular body and separating and restraining the loops of the adjacent cords by this, for adhesion fixing of the fiber cord or molding pressure during the whole covering molding with the rubber elastic body in the next step. , It is designed to prevent the fiber cords from biting or disturbing each other and deteriorating during long-term use of the joint.

However, in such a conventional example, although the fiber cord to be used is polyamide fiber or polyester fiber having a large elongation and is vulcanized, it is bonded and fixed with a soft material such as rubber glue. However, when used as a flexible joint, even if tensile force acts between two adjacent tubular bodies, the fiber cords that have been wound multiple times overwhelm the stress relatively evenly and are proportional to the number of turns. Since strength is expressed, there are few problems, but inorganic fibers such as glass fibers, carbon fibers, alumina fibers, and silicon carbide fibers, or organic fibers such as aramid fibers, which have high strength but low elongation, are used alone or When used in combination, because it is adhesively fixed with a flexible material, the fibers wound in the upper layer tend to slip into the lower layer when pulled,
The strength does not increase in proportion to the number of turns, and when higher strength is required, it is necessary to fix it with a hard material such as epoxy resin. In this case, the fiber is impregnated through the epoxy resin tank as in the conventional method, and after it is wound many times between both tubular bodies, the epoxy resin is heat-cured and bonded to the tubular body. Since both parts (stretched parts) are also made of hard resin to be focused and hardened into a rod shape, when a flexible joint is constructed by assembling such constrained elements, it is advantageous in terms of torque transmission strength in the torsional direction, but especially in terms of rigidity. There is a problem that the rigidity in the direction parallel to the driving shaft and the driven shaft becomes excessive, which is not preferable as a flexible joint.

Therefore, the applicant of the present invention, in Japanese Patent Application No. 5-86099, limits the adhesive fixation using a rigid resin material such as an epoxy resin only to the portion where the fibers come into contact with both tubular bodies (hereinafter referred to as the winding portion), Fibers in the other parts are not impregnated, and a flexible joint that achieves low rigidity in the axial direction while maintaining torsional strength and a manufacturing method thereof are proposed.

[0005]

However, in order to bond and fix in this way, it is necessary to apply the epoxy resin or the like, which is retained only to the winding portion which comes into contact with both the tubular bodies, on the reinforcing fiber. It should be noted that the application is possible even by relying on manual work with a spatula, etc., but if the application frequency is taken into account when winding a very large number of times and it is necessary to apply it at a predetermined position with high precision, an automated application device is used. Work is required.

The object of the present invention is to solve the above-mentioned conventional problems, to maintain sufficient strength in the torsional direction which is the main functional condition as a flexible joint, and to maintain the axial direction between the shafts. It is an object of the present invention to provide and provide a manufacturing method and a manufacturing apparatus therefor capable of flexibly responding to the displacement of the above and absorbing the displacement, and efficiently manufacturing a flexible joint of stable quality.

[0007]

In order to achieve the above object, a flexible joint manufacturing apparatus according to the present invention is a flexible joint manufacturing apparatus in which a reinforcing fiber is wound around two outer cylinder members. A holder for holding two outer cylinder members on the same plane with a predetermined space therebetween, and a reinforcing fiber arranged between the winding parts of the two outer cylinder members while rotating the holder around the center of the space. A winding means for winding in a laminated state, and an applying means for applying an adhesive to a portion of the reinforcing fiber that is pressed while being rolled and is limited to the winding portion and is wound around the winding portion,
It is characterized in that it is provided with a pressing means for pressing the applying means toward the winding part and an adhesive supplying means for supplying the adhesive to the applying means.

Further, in the method for manufacturing the flexible joint according to the present invention, the two outer cylinder members provided on the drive shaft side and the driven shaft side are held by the holder on the same plane with a predetermined space, While the holder is rotated around the center of the predetermined interval by the winding means, the reinforcing fibers are wound in an array and laminated state between the winding portions of the two outer cylinder members, and the applying means is pressed by the pressing means to wind the winding. An adhesive is applied to the reinforcing fibers wound around the winding portion while pressing only on the winding portion, and the bundle of reinforcing fibers is fixed to the winding portion by the adhesive to fix the two outer portions. It is characterized in that a link element composed of a tubular member and a reinforcing fiber bundle is configured.

[0009]

According to the present invention, the two outer cylinder members are held in the holder at a predetermined interval, the holder is rotated about the center of the interval, and the two outer cylinder members are wound between the winding parts of the two outer cylinder members. The reinforcing fiber is wound by means. Then, the adhesive is applied to the wrapping portion by the applying means that is pressed by the pressing means to the wrapping portion. Then, the reinforcing fiber bundle of the winding part that is in contact with the outer cylinder member of the link element formed by winding the reinforcing fiber bundle between the outer cylinder members a plurality of times is adhered and fixed by an adhesive, and The strength can be increased and the rigidity of the stretched portion between the outer tubular members can be kept low,
As described above, the strength in the torsional direction and the absorption of the displacement in the axial direction are caused to be shared by the respective link elements, whereby a flexible joint with stable quality can be efficiently manufactured.

[0010]

Embodiments of the present invention will be specifically described below with reference to the drawings.

Example 1 FIG. 1 shows an example of the construction of a flexible joint manufactured according to the present invention as viewed from the axial direction. In FIG. 1, 1 is a point 0.
A total of three first inner cylindrical members respectively connected to circumferentially trisecting positions on the side of a drive shaft (not shown) that is rotationally driven around the axis shown by, and 2 is coaxial with the drive shaft It is a total of three second inner cylinder members that are connected to a circumferential trisecting position on the rotatable driven shaft (not shown) side. The three first inner cylinder members 1 and the second inner cylinder members 2 are alternately arranged at equal intervals with a central angle of 60 degrees centered on the point 0, and adjacent first and second inner cylinder members 2 are arranged. A total of six elastic links L are wound between the tubular members 1 and 2.

These elastic links L are fitted into the inner tubular members 1 and 2 by press fitting, and the outer tubular member 3 with a pair of both end flanges 3A.
As shown in FIG. 2, the reinforcing fibers 4 such as glass fibers are wound in a plurality of layers so as to be layered between them, and the reinforcing fibers 4 are wound in contact with the outer tubular member 3.3. Only the attached portion P is bonded and fixed with a hard resin having an excellent adhesive force such as an epoxy resin. The reinforcing fiber bundle 4A of the stretched portion Q other than the winding portion P is not coated with the hard resin such as the epoxy resin described above, but is impregnated with, for example, low-viscosity silicone oil, or the reinforcing fiber bundle 4A is made of rubber. It is coated with an elastic material to improve durability.

Alternatively, even if the portion where the reinforcing fiber bundle 4A comes into contact with the outer edge of the outer tubular member flange portion 3A is impregnated with urethane rubber so as to isolate them from each other, the durability is improved in the same manner as described above. In FIG. 1, the reinforcing fiber 4 is provided only on two of the six elastic links L,
Illustration of the other four is omitted. Then, a total of six elastic links L are formed into a regular hexagonal shape as shown in FIG. 1 by press-fitting and fixing the inner peripheral portions of the outer cylindrical members 3 to the outer peripheral portions of the inner cylindrical members 1 and 2 adjacent to each other. Be integrated. Then, after that, the outside of the elastic link L is covered with the rubber elastic body 5 (see FIG. 1) to form the flexible joint member 10.

Next, a method for manufacturing such a flexible joint and a manufacturing apparatus will be described in detail with reference to the drawings.

Incidentally, this time, in order to compare the flexible joint manufactured by the manufacturing apparatus of the present invention with the flexible joint manually manufactured by using a spatula or the like, six flexible joints 10 are constructed as shown in FIG. Only one of the elastic links L was manufactured.

FIG. 3 shows a winding machine having a winding mechanism and a coating mechanism, which is a manufacturing means of the present invention. In the figure,
Reference numeral 20 is a holder that holds a pair of outer cylinder members 3 having flange portions 3A that are parallel to each other at both ends so as to maintain a predetermined interval. 21 and 22 correspond to the winding means of the present invention, and 2
Reference numeral 1 denotes a holder drive shaft that supports the central portion of the holder 20 in a direction orthogonal to the holder 20, and drives the holder 20 to rotate.
Reference numeral 2 is a traverse head for tensioning the reinforcing fiber 4 between the pair of outer cylinder members 3. The traverse head 22 is formed by laminating the outer cylinder member 3 with the specified number of windings of the reinforcing fibers aligned so as to traverse the flange portions 3A at both ends in the axial direction. is there. Reference numeral 23 denotes a winding machine housing that supports the holder drive shaft 21 and the traverse head 22 and houses a drive mechanism (not shown) for these.

The reference numeral 24 is a disk for rolling while contacting the outer peripheral surface of the reinforcing fiber 4 wound between the outer tubular members 3 and 3, and transferring and applying an adhesive to the reinforcing fiber 4 during that time (hereinafter referred to as a coating disk). Which is equivalent to the coating means of the present invention. Coating disc 2
In the case of this example, the shaft 24A of No. 4 is the shaft center 21 of the holder drive shaft 21.
It is slidably held in a long groove 25 provided along a line 25A passing through A. The coating disc 24 holds the adhesive as shown in FIGS.
It has a groove (hereinafter referred to as an adhesive holding groove) 24B for guiding the adhesive upward, and the adhesive is constantly supplied from the adhesive supply disc 26 to the holding groove 24B during the rotation thereof. The holding groove 24
B is formed to make it easier to hold the adhesive,
It can be omitted. The adhesive supply disk 26 is swingably supported by a cylinder 27 via a connecting rod 28, and the adhesive supply disk 26 itself along the guide groove of the side plate a.
The coating disc 24 is rotated in conjunction with the rolling movement of the coating disc 24. 29 stores the adhesive and continuously supplies the adhesive supply disk 26.
A dispenser (adhesive replenishing device) for replenishing the adhesive. The adhesive supply disk 26 and the dispenser 29 are the adhesive supply means of the present invention, and the cylinder 27
And the connecting rod 28 are the pressing means of the present invention.

In the coating mechanism having such a structure, by rotating the holder 20 by the holder drive shaft 21 of the winding machine, the pair of outer cylinder members 3, 3 supported by the holder 20 is moved around the drive shaft 21. Traverse head 22 while rotating
3A is reciprocated at a pitch between the flange portions 3A, 3A of the outer tubular member 3 in a direction orthogonal to the drawing in FIG. In this way, the reinforcing fiber 4 can be laminated in the form of being aligned between the prescribed winding outer cylinder members 3, 3. During that time, since the cylinder 27 applies a pressing force to the application disk 24 via the connecting rod 28 to the adhesive supply disk 26, the supply disk 26 rotates as the application disk 24 rotates. Meanwhile, the adhesive continuously supplied from the adhesive supply device 29 to the peripheral surface thereof can be transferred to the adhesive holding groove 24B of the coating disc 24.

Subsequently, the operation of applying the adhesive by the application disc 24 only to the contact portions (wrapping portions) of the pair of outer cylindrical members 3 and 3 shown with P in FIG. This will be described with reference to FIG.

For easy understanding in terms of geometry, the outer cylinder members 3, 3 forming a pair by the holder 20 will be described as being held horizontally as shown in FIG. Now, in FIG. 5, this horizontal line is H-H
And Therefore, in this state, the drive shaft 2 is placed on the horizontal line H-H.
There is a shaft center 21A of 1 and a shaft center 30A of the support cylinder 30 that supports the outer cylinder member 3 on the holder 20. Further, in FIG. 5, 3S and 3F respectively indicate the outer cylinder member 3 at the beginning and end of winding of the reinforcing fiber 4 on the outer cylinder member 3.
Furthermore, a circle 3AA indicated by a broken line in the outer cylinder member 3S
Is the winding cylinder at the beginning of winding, and also the outer cylinder member 3F
A circle 3BA indicated by a broken line in FIG. 3 indicates an outer peripheral portion when the reinforcing fiber 4 is completely wound around the winding cylinder 3AA. The long groove 25 regulates the displacement area of the coating disk 24. In the case of this example, the extension line of the center line 25A of the long groove 25 is the drive shaft 21.
The center line 25A is kept at an angle of 45 ° with the horizontal line H-H while being coincident with the axis 21A. The long groove 25 that regulates the displacement area of the coating disc 24 is set in this direction so that the pressing force acting on the winding portion P is equalized as much as possible.

At the beginning of winding the reinforcing fiber 4, the coated disk 24 has its axis 24A positioned at the upper end of the long groove 25.
At the end of winding, the shaft center 24A is located at the lower end of the long groove 25, but in any case, the cylinder 27 (see FIG.
(See (A) of), the pressing force generated by the supply disc 2
It acts substantially evenly on the outer cylinder member 3 side via 6. And at the start of winding (when the shaft center 21A and the shaft center 24A are closest to each other)
In this case, as shown in FIG. 5, the axis 24A of the coating disk 24 is on the center line 25A of the long groove 25 and the axis 30A of the support cylinder 30.
It is located on the vertical line passing through. As a result, when the shaft center 24A approaches the shaft center 21A on the center line 25A, the adhesive is applied to parts other than the portion P shown in FIG. And holder 20
The adhesive is supplied from the coating disc 24 that rolls along the winding cylinder 3AA of the outer cylinder member 3 shown in FIG. In addition, the holder 20 shown in FIG.
When the adhesive is applied to the right half of the winding cylinder 3AA shown in FIG. 5 by rotating 90 ° from the position, the application disk 24 is separated from the reinforcing fiber 4 being wound by the regulation by the long groove 25.

The above-mentioned coating operation is continued until the predetermined winding of the reinforcing fiber 4 around the winding cylinder 3AA of the outer tubular member 3 is completed and the outer peripheral portion becomes 3BA, during which the coating disc is applied. The movement of 24 is restricted by the long groove 25 while moving along the long groove 25, and the adhesive is applied to the region (wrapping part) P of the outer cylinder member 3 shown in FIG. In other words, the coating disc 24 is gradually displaced according to the number of windings while the position of the shaft 21 of the holder 20 is changed.
The winding portion P reciprocates approximately two times along the long groove 25 during one rotation around A, and the reinforcing fiber 4 contacts the outer tubular member 3 in diagonal regions of 90 degrees in each rotation (see FIG. 2). ) Is almost limited to the application of the adhesive.

The extension of the center line 25A of the long groove 25 does not have to pass through the axis 21A of the drive shaft 21. In short, when the shaft center 24A and the shaft center 21A are closest to each other, the shaft center 24A
On the line segment connecting the shaft center 21A and the shaft center 30A, the shaft center 24A
The angle between the center line 25A and the horizontal line H-H can be set arbitrarily as long as it lies on a line segment such that the dotted line connecting the axis 30A and the axis 30A is orthogonal.

In this embodiment, as the reinforcing fiber 4, the para-amide fiber yarn of No. 1000 is wound in a layered manner for 68 turns, while the contact portion P is formed as described above.
The epoxy resin (epoxy equivalent of 190 and modified heterocyclic amine-based curing agent mixture) is mixed with about 1% of a black colorant so that the coating condition can be easily confirmed, and the surface is a silicone rubber coated disc. 24 was applied. After completion of this winding, the glass fiber yarn of count 135 is continuously wound while applying 400 turns in a layered manner in the same manner, and after the winding is finished, it is heated and cured in an oven at 80 ° C. for 3 hours to make the fiber bundle an outer cylinder. It was adhered and fixed to the member 3.3.

Next, in order to isolate the contact portion between the fiber bundle 4A and the outer edge of the flange portion 3A from each other, a liquid urethane rubber (isocyanate prepolymer and polyol two-component urethane rubber is used to cure the rubber hardness). JI
S40A) was impregnated and cured at 60 ° C. for 2 hours. Also,
A low-viscosity silicone oil (5
1 g of (about 00 centistokes) was applied to impregnate the inside of the fiber. Set it in the mold in this state,
The urethane rubber (rubber hardness JIS40A) corresponding to the rubber elastic body 5 shown in FIG. 1 was cast on the outer side of the bundle 4A of the reinforcing fibers 4 and then heat-cured in a furnace at 60 ° C. for 4 hours and taken out from the mold. One elastic link L (Sample 1) was produced. In contrast, an elastic link (Sample 2) was produced by the same operation except that the same epoxy resin was manually applied to the winding part P once every 40 turns with a spatula (small spatula). Table 1 shows the epoxy coating amount of both samples and the breaking strength when the space between both outer cylinders is pulled. It can be seen from the table that the breaking strength of Sample 1 according to the present invention is almost equal to or even better than that of Sample 2. That is, the sample 1 is applied every one turn instead of the application for every certain number of turns in order to reduce the number of times of application as in the case of the comparative sample 2, so uniform application is achieved, and the epoxy resin application range is also the fiber bundle link. It is considered that this is because the coating is performed with high precision and substantially limited to the winding portions that make contact with the pair of outer cylinder members 3 and 3 forming L.

In this embodiment, the epoxy resin is supplied from the adhesive replenishing device 29 to the supply disk 26 that rotates while being in contact with the application disk 24. However, the application disk 24 has a dispenser having a discharge nozzle. The replenishment may be made directly, or the replenishment is not limited to the above-described dispenser method, and may be made to flow down from a slit attached to the storage tank, for example.

In the present embodiment, silicone rubber was used as the material for the coated disc 24 in consideration of the transferability of the epoxy resin, but the material is not limited to this, and urethane rubber, fluororubber, NBR, thermoplastics are also considered in consideration of durability. An elastomer or the like may be used.

[0028]

[Table 1]

Example 2 With the apparatus used in Example 1, only the curing agent for the epoxy resin was used and the pot life at room temperature (catalog value) was about 30 minutes TTA.
(Triethylenetetramine) was used at a winding speed of 200 turns / minute, and the link element L was constructed by winding up to the glass fiber yarn in a coatable state in which the epoxy resin was not gelled. In the case of 2), the limit was 2 to 3, but in the case of this example, 10 or more could be manufactured, and a great effect was obtained in terms of improving the manufacturing efficiency.

Example 3 In order to delay the curing of the epoxy resin on the surface of the coating disk 24 in the apparatus used in Example 1 and to utilize the high productivity of the apparatus according to the present invention, a curing agent for the epoxy resin can be applied at room temperature. A boron trifluoride compound having a very long working time was used instead. The curing conditions were 120 ° C. and 3 hours. As a result, the breaking strength was not different from that of Sample 1 of Example 1, but it was possible to eliminate the operational restriction due to gelation of the epoxy resin at room temperature. From this point of view, other curing agents having a long pot life, such as (imidazoles and endomethylenetetrahydrophthalic anhydride), may be used.

Fourth Embodiment In the first embodiment, a cylinder with a piston is used as a pressing force generating device for pressing the coating disk 24 to the re-approaching position so that the fluctuation of the pressing force transmitted through the center of the disk is small. However, this was replaced with a coil spring, and the same pressing force of about 6 N was used. In this case, there was no difference in breaking strength as compared with Sample 1 of Example 1, but it appeared to be slightly inferior in coating uniformity by visual observation. This is the coating disc 2
It is considered that the pressing force on No. 4 slightly varies depending on the position of the disc. In order to reduce such an influence and achieve a constant coating amount, a groove for storing an adhesive or an adhesive holding groove 24B as shown in FIG. It is effective to use a means for maintaining a constant contact force between the supply disk 26 and the supply disk 26.

Although silicone oil is used as the oil to be impregnated in the stretched portion Q in the above-mentioned embodiment, it is not limited to silicone oil and has low volatility at high temperature and can retain fluidity and activity even at low temperature. It is preferable to use various liquid oils having the properties of, for example, liquid paraffin,
A lubricant such as glycol monoether, a softener such as naphthene-based or paraffin-based, and a plasticizer such as dioctyl phthalate can be used.

By manufacturing the flexible joint by the apparatus and method described in the above embodiment, the reinforcing fibers such as glass fiber wound between the two outer tubular members in multiple layers are formed on the individual outer tubular members. A sufficiently high torsional strength can be maintained by being fixed by adhesion with a tough adhesive such as an epoxy resin. Further, the adhesive fixation with such a tough adhesive is limited to the winding portion with the outer cylinder member, and the stretched portion between the outer cylinder members is impregnated and covered with a rubber elastic body or the like capable of maintaining flexibility. By doing so, the rigidity can be kept low so as to allow axial displacement, and wear and damage due to misalignment between fibers are prevented against repeated stress of tension and compression generated in the winding part, and fatigue is prevented. The durability can be improved.

[0034]

As described above, according to the method for manufacturing a flexible joint and the manufacturing apparatus therefor according to the present invention, there is provided a flexible joint manufacturing apparatus in which reinforcing fibers are wound around two outer cylindrical members, A holder for holding the outer cylinder member on the same plane with a predetermined space, and a state in which reinforcing fibers are arranged and laminated between the winding parts of the two outer cylinder members while rotating the holder around the center of the space. A winding means for winding around, a coating means for applying an adhesive to a portion of the reinforcing fiber that is pressed while being rolled and limited to the winding portion, and the coating. Since the pressing means for pressing the means toward the winding portion and the adhesive supplying means for supplying the adhesive to the applying means are provided, both the adhesive fixing of the outer cylinder member and the reinforcing fiber by the adhesive is performed. Can be applied only by the applying means by the applying means. Because they are not the integral focusing hardening of the rod-like by the adhesive increase the strength of the torsional direction of the link element,
In addition, the rigidity in the axial direction can be suppressed to a low level. In addition, the quality of link elements can be stabilized and high productivity can be achieved by substituting a complicated coating work that depends on human hands, by uniformizing the coating amount and the coating range. In addition, since the application work is speeded up, the restriction on adhesives with short pot life is relaxed, the range of adhesive selection is expanded, and the number of link elements that can be wound within the same pot life can be increased. can get.
