この発明は、等速ジヨイントのブーツ取付は方法に関し
、特に熱可塑性エラストマー製ブーツの取付は方法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for installing a boot of a constant velocity joint, and more particularly to a method for installing a boot made of thermoplastic elastomer.
等速ジヨイントの外輪と内輪のシャフトの間に装着され

示すようにシャフト１及び外輪２の外周面に複数の周溝
３を形成し、周溝３の部分にブーツ４の端部５を嵌め、
その外周面をバンド６により締付けるようにしている。A bellows-shaped boot that is attached between the outer ring and inner ring shaft of a constant velocity joint is generally attached by tightening the end of the boot with a band. In addition, if the boots are made of thermoplastic elastomer such as polyester resin, they are less flexible than rubber, so as shown in Fig. 3, and fit the end 5 of the boot 4 into the circumferential groove 3,
Its outer peripheral surface is tightened by a band 6.
なお、端部５の内周面には、位置決め用のリファが形成
される。Note that a positioning reference is formed on the inner circumferential surface of the end portion 5.
上記のごとき熱可塑性エラストマー製ブーツ（例えば、
商品名「ハイトレル」製のブーツ）は、通常の加硫ゴム

る。特にブーツ４の小径端部５においてその（引回が見
られる。Thermoplastic elastomer boots as described above (e.g.
Boots made under the trade name "Hytrel" have a large bending modulus of elasticity that is about 10 times that of ordinary vulcanized rubber (in other words, they have little flexibility), so the constant velocity joint takes a large operating angle and can be used for long periods of time. When used, it may be pulled out from the mounting part. Particularly, the (routing) can be seen at the small diameter end 5 of the boot 4.
この発明は、このような問題点を解決するブーツの取付
は方法を提供することを目的とする。The object of the present invention is to provide a method for installing a boot that solves these problems.
前記の目的を達成するために、この発明は熱可塑性エラ

ある。To achieve the above object, the present invention provides a method for attaching a thermoplastic elastomer boot to a constant velocity joint, in which a circumferential groove is formed on the outer peripheral surface of the constant velocity joint, and the boot is fitted onto the circumferential groove. High-frequency heating is applied from the outer periphery of the end, thereby heating the boot end of the constant velocity joint, and the inner surface of the boot end, which has softened or melted due to the heat, is partially fitted into the circumferential groove. .
第１図に示すように、シャフト１の外周面に従来と同様
の複数の周溝３を形成する。一方、前記の「ハイトレル
」製ブーツ４の小径端部５のまわりにエポキシ樹脂又は
ナイロン６６の複合材等でなる拘束リング８を嵌める。As shown in FIG. 1, a plurality of circumferential grooves 3 similar to the conventional one are formed on the outer peripheral surface of the shaft 1. On the other hand, a restraining ring 8 made of epoxy resin or a composite material of nylon 66 is fitted around the small diameter end 5 of the Hytrel boot 4.
小径端部５の内周面には、従来と同様の位置決めリブ７
が形成される。A positioning rib 7 similar to the conventional one is provided on the inner peripheral surface of the small diameter end 5.
is formed.
上記の小径端部５をシャフト１の周溝３のまわりに嵌め
、拘束リング８のまわりに高周波加熱用コイル９を装着
する。しかるのち、この高周波加熱用コイル９に周波数
３０ ｋｌｌｚ、電圧２．５ＫＶ、電流２ＯＡの高周波
電流を約１３秒間流す。The small-diameter end 5 is fitted around the circumferential groove 3 of the shaft 1, and a high-frequency heating coil 9 is mounted around the restraining ring 8. Thereafter, a high frequency current having a frequency of 30 kllz, a voltage of 2.5 KV, and a current of 2 OA is passed through the high frequency heating coil 9 for about 13 seconds.
これにより、シャフト１が加熱され、その熱により端部

溝３の凹みに倣って部分的に嵌入する。第２図の符号１
０はその嵌入部を示す。As a result, the shaft 1 is heated, and the inner surface of the end portion 5 is softened or melted by the heat. Therefore, the end portion 5 follows the recess of the circumferential groove 3 and partially fits into it. Number 1 in Figure 2
0 indicates the inserted portion.
なお、拘束リング８は、加熱時に小径端部５が外周方向
へ膨張することを抑えるために使用される。Note that the restraining ring 8 is used to prevent the small diameter end portion 5 from expanding in the outer circumferential direction during heating.
以上はブーツ４の小径端部５の取付は方法について述べ
たが、大径端部を外輪の外周部に取付ける場合も同様で
ある。Although the method for attaching the small-diameter end 5 of the boot 4 has been described above, the same applies to the case where the large-diameter end is attached to the outer circumference of the outer ring.

は難い効果がある。また、従来のごとき締付はバンドを
必要としない効果もある。As described above, the present invention heats the shaft using high-frequency heating, indirectly heats the end of the boot using the heat, deforms the inner peripheral surface thereof, and improves the FiHJI of the boot attachment part of the shaft, etc. Since it is partially inserted into the shaft, the restraining force on the shaft of the boot, etc. is large, and it has the effect that it is difficult to remove even when the constant velocity joint takes a large operating angle. Further, conventional tightening has the advantage of not requiring a band.
