The present invention relates to a manufacturing method.

がある。(Prior art) In recent years, due to the demand for lighter power transmission shafts used in vehicles, etc., continuous fiber reinforced plastics (hereinafter referred to as F
The development of a power transmission shaft using a molded body made of FRP (RP) is progressing, but in this case, it is necessary to connect a metal yoke to both ends of the FRP pipe, and various methods have been used for this connection. Efforts have been made. For example, the joint part of an FRP pipe and a yoke may have a circular cross section, an elliptical cross section, or a polygonal cross section that can fit together,
There are methods of adhesive bonding after molding and hardening of RP pipes, press-fit bonding methods, and methods of incorporating the yoke itself or a part of it into a mandrel and rolling it in during filament winding to form FRP pipes. Yes, each has its advantages and disadvantages.
本願発明は、上記方法のうちＦＲＰ製パイプとヨークと
を圧入により結合する方法を改良したものである。The present invention is an improved method of joining the FRP pipe and the yoke by press-fitting among the above methods.

ている。By the way, in the case of the method of press-fitting a metal yoke into an FRP pipe, the joint part of the FRP vibrator suffers fatigue damage due to repeated application of driving force and braking force.
In addition, there is a problem that FRP is prone to delamination and adhesive layer peeling, and when looking at metal yokes,
Frequently, fretting occurs due to micro-friction occurring at the joint surface, which may lead to peeling of the adhesive layer. One method for dealing with these problems is to use an outer ring. For example, Utsukai 61-1626
As disclosed in Publication No. 19, after the fitting part of the yoke is press-fitted into the FRP vibrator, the pipe around the fitting part is tightened with an outer ring, so that the joint surface of the pipe and the yoke is tightened. A method has been proposed to make peeling less likely to occur.

発生することとなる。従って、疲労被害の抑制が不十分
となるおそれがある。(Problem to be solved by the invention) In the case of the above-mentioned known example, after the yoke is press-fitted into the pipe,
Since the outer ring is fitted while applying a compressive force to the outer circumference of the pipe that bulges out due to the press-fitting, the press-fitting process is performed twice at the same location, which slows down the manufacturing process. There is a risk that the process will become more complicated, and
There is also a risk of a decrease in press force due to creep phenomenon, etc. In addition, in the case of the above-mentioned known example, the transmission of torque between the pipe and the yoke depends only on the inner circumferential surface of the pipe, so most of the torque is transmitted near the fitting ends of the two. As a result, a high stress concentration occurs in that part. Therefore, there is a possibility that fatigue damage will be insufficiently suppressed.

When manufacturing a power transmission shaft by fitting and fixing the fitting part of the yoke to a plastic pipe,
With the outer ring set on the outer periphery of the end of the pipe, the fitting part of the yoke is press-fitted into the pipe, and the end of the outer ring and the yoke are coupled so as to be rotatable together during or after the press-fitting. That's what I do.

By connecting the outer ring end and the yoke so that they can rotate together, torque transmission between the yoke and the pipe is achieved not only from the inner circumferential surface of the pipe but also from the outer circumferential surface via the outer ring. It will be done.

効果がある。(Effects of the Invention) According to the present invention, when manufacturing a power transmission shaft by fitting and fixing a fitting portion of a yoke to a plastic 7-vee, an outer ring is attached to the outer periphery of the end of the pipe. Since the fitting part of the yoke is press-fitted into the pipe in the set state, the outer ring can tighten the pipe at the same time as the yoke is press-fitted, which simplifies the press-fitting process. This has the excellent effect of suppressing a decrease in press force due to creep phenomena and the like.

いう優れた効果もある。In addition, since the outer ring end and the yoke are connected so that they can rotate together during or after the yoke is press-fitted, torque transmission between the yoke and the pipe is transmitted not only from the inner circumferential surface of the pipe but also from the outer ring. This is also done from the outer circumferential surface via the ring, which has the excellent effect of suppressing wear due to micro-friction that occurs on the joint surfaces, as well as suppressing glabella peeling etc. even when the pipe is made of FRP. .
（実施例）
以下、添付の図面を参照して、本願発明にががる動力伝
達軸の製造方法を具体的実施例に基づいて説明する。(Examples) Hereinafter, a method for manufacturing a power transmission shaft according to the present invention will be described based on specific examples with reference to the accompanying drawings.

同構造とされる。In the case of this embodiment, as shown in Figure 2, the power transmission shaft A is
It is composed of a pipe 1 made of FRP, a metal yoke 2 connected to both ends of the pipe 1, and a metal outer ring 3 interposed between the two ends. Although only one end is shown in the drawing, the other end also has the same structure.

程を詳述する。The power transmission shaft A according to this embodiment is constructed by press-fitting the fitting part 2a of the yoke 2 into the pipe l with the outer ring 3 set on the outer periphery of the end of the vibrator l, and the It is manufactured by joining the end of the outer ring 3 and the yoke 2 so that they can rotate together, and the process will be explained in detail below.
まず、前記バイブｌは、公知の技術であるフィラメント

、アウターリング３との密着性を確保しておく。First, the vibrator I is molded and hardened by a known technique such as filament winding, and at least the part where the outer ring 3 is inserted (in other words, the part where the fitting part 2a of the yoke 2 is press-fitted) The outer circumferential surface of the outer ring 3 is made into a substantially perfect round and smooth surface by grinding or turning to ensure close contact with the outer ring 3.

(See Figure 1).

強度が高まり好都合である。Next, the outer ring 3 having such a structure is inserted while being positioned around the outer periphery of the end of the vibrator 1, and the part where the serrations 4 are formed extends from the end of the vibrator 1 as shown in FIG. considered to be in a prominent state. At this time, if adhesive is applied to the inner circumferential surface of the outer ring 3 or (and) the outer circumferential surface of the vibrator 1, voids, cracks, and recesses on the turned side of the outer circumferential surface of the pipe l will be filled, and the yoke 2 will be Tightening in the radial direction after press-fitting the fitting portion 2a is convenient because the surface pressure distribution is averaged with respect to the force. Furthermore, if the outer ring 3 and the vibrator L are adhesively bonded in advance (that is, the adhesive is hardened), even if the two are a loose fit, the appearance will be good and the gap will be zero. Therefore, yoke fitting part 2
The press-fitting effect at the time of press-fitting in a is effectively exhibited, which is more convenient. This effect is also convenient for transmitting torque via the outer ring 3. Note that the fit between the outer ring 3 and the vibrator 1 may be an interference fit, and even in this case, it is advantageous to apply an adhesive to increase the bonding strength.
続いてヨーク２の嵌合部２ａをパイプ１内に圧入するの
であるが、前記ヨーク２外周には、嵌合部２ａに続いて

ってバイブ１の端部付近が破壊するのを防止する。After the press-fitting of the yoke fitting portion 2a into the vibrator l is completed, the overlapping portion of the outer ring 3 and yoke 2 (i.e., the serration 4.6 portion) is subjected to cold plastic processing such as roll processing, press processing, or electromagnetic caulking. As a result, the outer ring 3 and the yoke 2 are coupled together so that they can rotate together. In the case of this embodiment, the serrations 4 of the outer ring 3
Since the serrations 6 of the yoke 2 and the serrations 6 of the yoke 2 are to be engaged with each other, the two are firmly connected. At this time, the groove 5 formed on the outer circumferential surface of the outer ring 3 facilitates plastic deformation of the caulked part (i.e., plastic deformation part) of the outer ring 3, and the stress generated at this time causes the end of the vibrator 1 to Prevent damage to the area around the part.

圧入力の低下も抑制される。As described above, in this embodiment, with the outer ring 3 set around the outer periphery of the end of the vibrator l,
Since the yoke fitting part 2a is press-fitted inside, the outer ring 3 can tighten the vibrator 2 at the same time as the yoke fitting part 2a is press-fitted, which simplifies the press-fitting process. , a decrease in press force due to creep phenomena and the like is also suppressed.

なる。Furthermore, since the end of the outer ring 3 and the yoke 2 are coupled together so that they can rotate together after the yoke fitting portion 2a is press-fitted, the torque transmission between the yoke 2 and the vibrator l is
This is done not only from the inner circumferential surface of the vibrator 1 but also from the outer circumferential surface via the outer ring 3. In particular, torque transmission from the outer circumferential surface of the vibrator 1 via the outer ring 3 can be achieved with low shear stress due to the difference in radius from the inner circumferential surface. Compared to the torque transmission of
The degree of fatigue damage caused by delamination or the like in manufactured pipes can be significantly suppressed. In addition, it is possible to reduce the pressing force, and since the outer ring 3 exerts a stiffening effect against the force in the bending direction between the vibrator l and the yoke 2, it also contributes to improving bending rigidity. becomes.

要がある。In the above embodiment, the overlapping portions of the outer ring 3 and the yoke 2 are plastically deformed and connected after the yoke fitting part 2a is press-fitted, but it is also possible to plastically deform and connect them simultaneously with the press-fitting of the yoke fitting part 2a. You can also. However, in this case, the press-in force is likely to be excessive and may cause damage to the FRP vibrator 1, so care must be taken when press-fitting.

が考えられる。In addition to the above embodiments, methods for joining the outer ring 3 and the yoke 2 so that they can rotate together include welding the overlapping parts of the two at a relatively low temperature such as electron beam welding, and using rivets. A possible method is to mechanically connect the two.
