Title (EN) UNIVERSAL JOINT AND YOKE
(FR) JOINT UNIVERSEL ET FOURCHE
Abstract:
(EN) A universal joint (4) includes a pair of yokes (20) and a joint cross (21). The pair of yokes (20) have mutually identical shapes. Each of the yokes (20) has a proximal portion (25) and a pair of arm portions (26) at which the joint cross (21) is mounted. The proximal portion (25) has an insertion hole (29) for mounting a shaft, a slit (27) formed along the insertion hole (29) and a bolt insertion hole (33) for fastening the slit (27). A positional relationship between the proximal portion (25) and the pair of arm portions (26) is set such that a line segment (X) that connects the pair of arm portions (26) to each other and an insertion direction in which a bolt (50) is inserted in the bolt insertion hole (33) intersect with each other at 45°. The bolt insertion holes (33) of the pair of yokes (20) coupled by the joint cross (21) face the same side.
(FR) L'invention concerne un joint universel (4) comprenant deux fourches (20) et un croisillon de joint (21). Les deux fourches (20) sont de forme mutuellement identique. Chacune des fourches (20) présente une partie proximale (25) et deux parties bras (26) au niveau desquelles est monté le croisillon de joint (21). La partie proximale (25) présente un trou d'insertion (29) pour le montage d'un arbre, une fente (27) formée le long du trou d'insertion (29) et un trou d'insertion (33) d'un boulon pour la fixation de la fente (27). La position relative entre la partie proximale (25) et les deux parties bras (26) est définie de telle manière qu'un segment de ligne (X) qui relie les deux parties bras (26) l'une à l'autre et la direction d'insertion dans laquelle un boulon (50) et inséré dans le trou d'insertion (33) se croisent à un angle de 45°. Les trous d'insertion (33) de boulons et les deux fourches (20) accouplées l'une à l'autre par le croisillon de joint (21) sont orientés vers le même côté.
