Title (EN) METHOD FOR ASSEMBLING CRUCIFORM UNIVERSAL JOINT, AND CRUCIFORM UNIVERSAL JOINT
(FR) PROCÉDÉ D'ASSEMBLAGE DE JOINT DE CARDAN EN CROIX ET JOINT DE CARDAN EN CROIX
(JA) 十字軸式自在継手の組立方法、及び十字軸式自在継手
Abstract:
(EN) A cup bearing (13a) is assembled inside a circular hole (11c) of a linking arm part (10c) constituting part of a yoke, after which a notch (25) having a V shape in a cross section is formed in a portion of the outer-side surface of the linking arm part (10c) that is near the periphery of the circular hole (11c). A thin part (27) having a substantial trapezoid shape in a cross section, the thin part (27) being formed in the radially inward portion of the notch (25) in the open edge part of the circular hole (11c), is then elastically deformed radially inward to form a crimped part (14a). Achieved thereby are a method for assembling a cruciform universal joint, and a cruciform universal joint, with which a crimped part for preventing a cup bearing from falling out can be formed without complicating the work of crimping.
(FR) L'invention concerne une crapaudine (13a) assemblée dans un trou circulaire (11c) d'une partie bras de liaison (10c) constituant une partie d'une fourche, après quoi une encoche (25) ayant une forme de V dans une section transversale est formée dans une partie de la surface du côté extérieur de la partie bras de liaison (10c) qui est proche de la périphérie du trou circulaire (11c). Une partie mince (27) ayant une forme sensiblement trapézoïdale dans une section transversale, la partie mince (27) étant formée dans la partie radialement tournée vers l'intérieur de l'encoche (25) dans la partie bord d'ouverture du trou circulaire (11c), est ensuite élastiquement déformée radialement vers l'intérieur pour former une partie sertie (14a). Il est ainsi obtenu un procédé d'assemblage de joint de cardan en croix et un joint de cardan en croix avec lesquels une partie sertie destinée à empêcher la chute d'une crapaudine peut être formée sans compliquer le travail de sertissage.
(JA) ヨークを構成する結合腕部(10c)の円孔(11c)内にカップ軸受(13a)を組み込んだ後、この結合腕部(10c)の外側面のうち円孔(11c)の周囲近傍部分に、断面V字形のノッチ(25)を形成する。その後、この円孔(11c)の開口縁部のうち、このノッチ(25)の径方向内側部分に形成された、断面略台形状の薄肉部(27)を、径方向内方に塑性変形させてかしめ部(14a)とする。これにより、かしめ作業を煩雑にする事なく、カップ軸受の脱落を防止する為のかしめ部を形成できる、十字軸式自在継手の組立方法、及び十字軸式自在継手を実現する。
