(JA) ステアリングラック及びその製造方法
Abstract:
(EN) Provided is a steering rack comprising: a rack shaft (10); a plurality of rack teeth (11a) that are provided on a rack shaft and that each have a tooth trace that is inclined with respect to a first direction which intersects the axial direction of the rack shaft; and dummy teeth (33a) provided on the rack shaft so as to be aligned with the rack teeth. The dummy teeth (33a) are provided non-uniformly in a second direction which is parallel to the tooth trace of the rack teeth (11a).
(FR) L'invention concerne une crémaillère de direction, laquelle crémaillère comprend : un arbre de crémaillère (10) ; une pluralité de dents de crémaillère (11a) qui sont disposées sur un arbre de crémaillère et qui ont chacune une ligne de flanc qui est inclinée par rapport à une première direction qui croise la direction axiale de l'arbre de crémaillère ; et des dents fictives (33a) disposées sur l'arbre de crémaillère de manière à être alignées avec les dents de crémaillère. Les dents fictives (33a) sont disposées de manière non uniforme dans une seconde direction qui est parallèle à la ligne de flanc des dents de crémaillère (11a).
(JA) ステアリングラックは、ラックシャフト(10)と、ラックシャフトに設けられ、ラックシャフトの軸方向に直交する第1方向に対して傾斜した歯筋を有する複数のラック歯(11a)と、ラック歯に並んでラックシャフトに設けられたダミー歯(33a)と、を備える。ダミー歯(33a)は、ラック歯(11a)の歯筋と平行な第2方向に関して非一様に設けられている。
