Abstract
(EN)
A power transmission chain in which connection members (50) are inserted into through holes (9, 10) in the link (2) of the chain (1). Each of the connection members (50) includes first and second pins (3, 4). The first and second pins (3, 4) are so formed that the pair of end parts (14, 15, 27, 28) thereof in an orthogonal direction (V) crossing perpendicularly to both a chain advancing direction (X) and a chain lateral direction (W) are received by receiving parts (38, 39, 40, 41) formed in the corresponding through holes (9, 10) in the corresponding link (2). At least one of the end parts (14, 15, 27, 28) includes curved surface parts (14, 15, 32a, 32a) received by the corresponding receiving parts (38, 39, 40, 41). The curved surface parts (14, 15, 32a, 32a) include top parts (20, 22, 33, 33) in the orthogonal direction (V), and the radii of curvatures of the curved surface parts (14, 15, 32a, 32a) are continuously or stepwise increased toward the top parts (20, 22, 33, 33).
(FR)
La présente invention concerne une chaîne de transmission de puissance dans laquelle des éléments de raccordement (50) sont insérés dans des orifices traversants (9, 10) dans la liaison (2) de la chaîne (1). Chacun des éléments de raccordement (50) comprend une première et une seconde broche (3, 4). La première et la seconde broche (3, 4) sont formées de sorte que la paire de leurs extrémités (14, 15, 27, 28) dans une direction orthogonale (V) croise perpendiculairement une chaîne avançant dans la direction (X) et qu'une chaîne dans la direction latérale (W) soit reçue par des parties de réception (38, 39, 40, 41) formées dans les orifices traversants correspondants (9, 10) dans la liaison correspondante (2). Au moins l'une des extrémités (14, 15, 27, 28) comprend les parties de surface incurvées (14, 15, 32a, 32a) reçues par les parties de réception correspondantes (38, 39, 40, 41). Les parties de surface incurvées (14, 15, 32a, 32a) comprennent des parties supérieures (20, 22, 33, 33) dans la direction orthogonale (V) et les rayons d'incurvation des parties de surfaces incurvées (14, 15, 32a, 32a) sont augmentés en continu ou par étapes vers les parties supérieures (20, 22, 33, 33).
