的構成とは云い難い。However, in the above-mentioned conventional example, the torque vibration absorbing member is formed in a half-moon shape so as to appropriately have both the tensile strength in the rotational direction and the rigidity in the axial direction. It is configured so that the six materials are combined and laminated, and as a result of the lamination, the material is located at one place (the area indicated by A to F in FIG. 2) and
The two-layered portion (the region indicated by G to K in FIG. 2) and the three-layered portion (not denoted by the reference numeral in FIG. 2 but correspond to the A to F regions in the radial direction). (The angular outer peripheral portion), and the laminated state is not uniform. In particular, when transmitting torsional torque between the drive shaft and the driven shaft, concentrated stress is generated in the vicinity of the bolt insertion hole (indicated by reference numerals 5 to 10 in FIG. 2). In the region (2), the lamination is constituted by the superposition of two regions, and between the bolt insertion holes, there are one and three laminated portions as described above, which is not rational in structure. In particular, in the region between adjacent bolts, one, two,
It is difficult to say that the configuration is rational because a combination of three stacked units is mixed.

Not only is such a torque transmission coupling unreasonable and undesirable. Furthermore, since the above-mentioned material naturally has a certain thickness, an interval for pressurizing is provided between the upper die and the lower die of the die when the material is laminated and pressed. The problem is whether to match the spacing to the unit of one layer or to the unit of three layers. In the case of the former, there is a risk that the other layer may be under-compressed. The strength of the improperly pressurized portion as described above is lower than that of the portion, and as a result of measures to prevent this, the shape of the mold is complicated.

When warp yarns are used, the warp yarns with high density are converged by the weft yarns, so there is no disturbance in the fiber direction at the time of lamination molding, and the warp yarns do not meander due to the weft yarns, and the warp yarn strength reinforcing effect is fully exhibited You. Further, since there is almost no reinforcing effect of the weft yarn, there is substantially no disadvantage in strength even if the arrangement is performed without considering the orientation direction thereof and only the warp yarn direction. Therefore, such a woven fabric is used as it is without modifying the crossing angle of the warp and woof, and is laminated only in the warp direction.

枚である。In the present embodiment, one unit is composed of a large plate material 10-1, 10-2, and 10-3 as shown in FIG.
One made of three circular materials of 0 mm was cut out and prepared for three units. The prepreg used here was prepared by impregnating a 0.16 mm thick woven T-glass fiber yarn with Turkish resin and impregnating it with an epoxy resin to prepare a prepreg. Depending on the fiber diameter and the number of warp and weft yarns, the fiber density was However, the strength in the vertical direction is about six times greater than the strength in the horizontal direction. Here, T glass fiber belongs to S glass fiber,
It is strong in the tensile direction and weak in the bending direction, and is a registered trade name of Nitto Boseki Co., Ltd. FIG.
In the coupling based on the shape of the above, stress concentration of about 2.4 times occurs around the connection holes 2 and 3 having a diameter of 10 mm. In view of the fact that it is desired to be about 2.4 times as large as the transmitting portion 5 and that it is not desired to increase the rigidity in the axial direction, the fan-shaped flat portion of the bolt hole reinforcing portion is taken into consideration in consideration that the number of stacked torque transmitting portions 5 is not desired to increase.

12 as a mold for lamination pressure molding, and a cylindrical upper mold and a lower mold (fitting therewith)
In order to form the fan-shaped flat washer 4 of the bolt hole reinforcing portion having a large thickness on the surfaces in contact with the upper and lower mold materials 10 and 12, the fan-shaped engraving corresponding to the shape is adjusted so that the relative position is adjusted. Is prepared, and the surface is subjected to a release treatment using, for example, a coating type release agent. Then, the lower mold is inserted into the side mold. First, three pieces of fan-shaped material 60 mm and two pieces of 0 mm are taken. In the above-mentioned lower die, a direction of −60 ° (inverting a direction of 60 °), a direction of 0 °, 60 °, 0 °, and −60 ° are laminated in order in one fan-shaped engraving. Do this for the other five engravings. On top of this, the circular materials 10-1, 10-2, and 10-3 of FIG. 3 are stacked in a unit, for example, the one in the 0 ° direction so as to match any one of the diameter directions connecting the connection holes 2 and 3. Next, six fan-shaped materials are placed one by one in accordance with the position of the lower fan-shaped engraving.
The layers are laminated so as to be in the direction of 60 °, respectively. The prepregs may be appropriately heated by a heating iron so as to be softened and fused to each other so as not to be displaced from each other when the materials are laminated. Then, a circular material is laminated on this one unit, facing each other in the same manner. Further, the fan-shaped materials are stacked on each of the six portions in the -60 ° direction one by one. Further, one unit of the circular material is similarly laminated. On top of that, there are 5 fan-shaped materials at each location, 60 ゜, 0 ゜, -60 ゜, 0 ゜,
Laminate to 60 °. Thus, when the line connecting the bolt connecting holes 2 and 3 adjacent to each other is set to 0 ° in the bolt hole reinforcing portion and the bolt transmitting holes 2 and 3 in the torque transmitting portion, the fiber directions are -60 °, 0 °, and 60 °.゜ is repeated three times in this order and 9
This means that the layers are stacked. Finally, the upper mold was fitted into the lower mold in accordance with the position of the fan engraving.

These fan-shaped cutouts 12 have a φ10 mm hole on both sides and the symmetry axis of the fan-shaped cutouts 12 at both sides of the circular cutouts 11 to constitute the fan-shaped flat washers 4 for bolts shown in FIG. The bolts are bonded in the direction of the diameter connecting the centers of the connection holes 2 and 3 for bolts. Note that, of the circular cut-out 11, the portion where these are not bonded is the intermediate portion (torque transmitting portion) 5 in FIG. 1. For this purpose, after roughening and degreasing the bonding surface of both, an epoxyphenol-based adhesive is applied, and after evaporating the solvent, the two are combined and pressurized at a surface pressure of 230 MPa at 180 ° C. for 2 hours.

を選定する必要がある。In this embodiment, the prepreg of the epoxy resin matrix is used as the material, but the material is not limited to the epoxy resin, and a thermosetting prepreg such as an unsaturated polyester resin or a phenol resin may be used. Further, a thermoplastic resin-based prepreg may be used, or a combination of a matrix-unimpregnated reinforcing fiber and a thermoplastic resin film or fiber which is to be melt-impregnated in a heating lamination step in a woven form may be used. Examples of such a thermoplastic resin include polyamide, polyester, polypropylene, polyethylene, polystyrene, polycarbonate, polyetherimide, polyphenylene sulfide, and polyetheretherketone. Further, the type and form of the reinforcing fiber are not limited to those in the above-described embodiment, and inorganic fibers such as E glass fiber, carbon fiber, alumina fiber, alumina-silica fiber, silicon carbide fiber, and metal fiber, and organic fibers may be used. Aramid fibers, polyphenylene sulfide fibers, etc. can be used as long as they have a melting point higher than the heat curing temperature or the melting temperature during lamination. These fibers are used in a form of large anisotropy, such as Turkish satin weave, with a difference in strength in the vertical and horizontal directions. In the above-described embodiment, the disc coupling is a flat hexagonal disc. However, the disc coupling is not limited to this. For example, an octagonal disc coupling having four connection holes for the drive shaft and the driven shaft has a circular shape. As a material of the plate-shaped laminated molded product for the shape cutout, a set of four sheets whose fiber longitudinal directions are shifted from each other by 45 ° may be used.
Further, the number and direction of lamination of the plate-shaped laminated molded product for a fan-shaped cutout are not limited to those in the above-described embodiment. In the embodiment, the fiber longitudinal direction is 90 ° with respect to the symmetry axis of the fan-shaped cutout.

た方法を代替えすることができる。As described above, in the present embodiment, the required number of circular materials are overlapped in the prepreg stage in such a manner that a plurality of circular materials can be obtained at the stage of prepreg, and the longitudinal direction of the fibers is aligned with the specified direction. After heating and curing to form a large plate-shaped laminated molded product, it is cut into circular cutouts by appropriate means, so that a large number of one component of the disk coupling can be obtained. Similarly, by obtaining a large-sized laminated molded product and then forming a fan-shaped cutout, a large number of other components can be obtained. And by bonding the required number of the latter to the bolt hole reinforcement part position using the former one,
One disk coupling is obtained. By repeating this bonding process for the remaining components, a plurality of disk couplings can be manufactured. Thus, as in the conventional example, the necessary number of circular materials and sector materials are cut out in consideration of the required number of fibers and the fiber direction individually, and a large number of these materials are inserted into the same mold at the designated fiber orientation and position. By curing and integrating, it is possible to replace the method of obtaining one disk coupling.

The circular cut-out 11 having the number 3 was cut out one by one without being combined. At this time, the fiber was cut out so that any one of the diagonal lines of the hexagonal hole 7 and any one of the diameters passing through the centers of the opposed connection holes 2 and 3 coincided with the longitudinal direction of the fiber. Next, in order to similarly bond the fan-shaped flat washer 4 as a peripheral reinforcement of the connection holes 2 and 3, the bonding surface of the two was roughened and degreased, and then an epoxyphenol-based adhesive was applied to evaporate the solvent. Thereafter, the two were combined and heated at 180 ° C. for 20 minutes while applying a pressure of 230 kPa to obtain a coupling having the shape shown in FIG.

点より低いものを選定する必要がある。In this embodiment, the prepreg of the epoxy resin matrix is used as the material, but the material is not limited to the epoxy resin, and a thermosetting resin prepreg such as an unsaturated polyester resin or a phenol resin may be used.
Further, a thermoplastic resin-based prepreg may be used, or a combination of a reinforcing fiber not impregnated with a matrix and a thermoplastic resin film to be melt-impregnated in a heating lamination step or a fiber in a woven form may be used. Examples of such a thermoplastic resin include polyamide, polyester, polypropylene, polyethylene, polystyrene, polycarbonate, polyetherimide, polyphenylene sulfide, and polyetheretherketone. In addition, the type and form of the reinforcing fiber are not limited to the above-described embodiment, and inorganic fibers such as E glass fiber, carbon fiber, alumina fiber, alumina-silica fiber, silicon carbide fiber, and metal fiber, and organic fibers may be para-based. Aramid fibers, polyphenylene sulfide fibers, etc. can be used as long as they have a melting point higher than the heat curing temperature or the melting temperature during lamination. These fibers are used in a form of large anisotropy, such as Turkish satin weave, with a difference in strength in the vertical and horizontal directions. Also, the number of sets used can be increased or decreased according to the required specification of torsional strength. Furthermore, although the above-described embodiment is a flat hexagonal disk coupling,
Without being limited to this, for example, in the case of an octagonal shape having four connection holes for the drive shaft and the driven shaft respectively, the material of the plate-shaped laminated molded product for the circular cutout is in the fiber longitudinal direction. What is necessary is just to make a set of four sheets shifted by 45 ° from each other. In addition, in the above embodiment, the appearance is a disk shape, but the material, a fan-shaped flat washer, molding, post-processing, etc. are used so that the material becomes a dodecagon with an outer contour dropped in consideration of weight reduction and the like. May be modified. Also, the adhesive used for bonding the circular molded product or the circular cutout to the metal fan-shaped flat washer may be epoxy resin, phenol resin, acrylic resin, or the like. However, in the case of a prepreg using a thermoplastic resin as a matrix, it is of course necessary to select a prepreg having a curing temperature lower than the melting point of the matrix resin.

The disk coupling for transmitting the rotational torque requires connection holes for attaching to the drive shaft and the driven shaft. In this case, since stress concentration occurs, reinforcement is necessary at this portion. In the conventional example, this is dealt with by increasing the number of layers using the same material. The additional portion is integrally incorporated at the time of forming the coupling by lamination, or the additional portion is separately formed by lamination and bonded to a portion requiring reinforcement in a post-processing manner. The metal fan-shaped flat washer, which is a heterogeneous material used in the present invention, can be replaced with a fan-shaped material integrally incorporated or a reinforcing material separately laminated and molded. Furthermore, the conventional disk-shaped flat washer used for dispersing the compressive stress due to bolt tightening when attaching to the drive shaft and the driven shaft is replaced with a fan-shaped flat washer having a larger supporting area to further distribute the stress. .

The high strength of the reinforcing fiber can be coordinated in many longitudinal directions, so high transmission torque can be obtained.Moreover, the whole area of the torque transmission part between both holes has the same number of layers, and there is no break in the laminated material. Because it does not occur, there is no weak point in strength.On the other hand, the density of the horizontal fibers is low, so that the vertical fibers do not meander up and down. As a result, the strength of the longitudinal fibers is sufficiently exhibited, and a coupling with high efficiency, high transmission torque, and low shaft rigidity can be obtained.

The circular cutout and the fan-shaped cutout cut out from any place in the obtained large-size laminated molded product are also configured from the designated fiber direction and the number of laminated layers, and these cutouts are According to today's numerically controlled processing machine, it is easy, and therefore, it is only necessary to align and bond the latter to the former bolt hole reinforcing part position, and a large number of circular materials as in the conventional example,
The number of man-hours required for cutting and arranging the fan-shaped material in each direction and arranging it in the mold are greatly reduced, and a large number of circular cuts and fan-shaped cuts can be taken from large-sized laminated moldings. The effect is obtained that the poor rotation rate of the conventional die for the sheet taking is also improved.

という効果が得られる。Further, when reinforcing the periphery of the connection hole in response to stress concentration around the connection hole, the same material is used to increase the number of laminations in this portion, and this is integrated with the coupling during lamination molding of the coupling. In the case of a conventional example in which the molding is incorporated into a mold, a step of cutting out a fan-shaped material as a reinforcing material for each sheet in a number of defined directions and arranging and laminating the cut pieces in a defined direction position is a step of the present invention. According to the method, the number of steps can be reduced because a much smaller number of metal fan-shaped washers can be replaced. In addition, even in the case of a conventional example in which the number of laminations is increased by forming a large number of pieces in a separate process, cut out, bonded in a later process, and furthermore, a conventional circular flat washer is bonded, the metal fan Since it is replaced only by the bonding of the shape washer, the number of steps is similarly reduced. In addition, compression deformation around the connection hole due to the tightening force of the mounting bolt causes the bolt to loosen,
In order to prevent this, the stress distribution by the flat washer is further increased by increasing the supporting area by the fan-shaped washer, so that the stress is further dispersed and the looseness is reduced. Since the area is increased, the effect of increasing the torsional strength is obtained.
