Title (EN) SILENT CHAIN TRANSMISSION
(FR) TRANSMISSION PAR CHAÎNE SILENCIEUSE
(JA) サイレントチェーン伝動装置
Abstract: front page image
(EN) Provided is a silent chain transmission capable of reducing wear of teeth. The present invention relates to a silent chain transmission (1) including a silent chain (3) and a sprocket wheel (2). The contour of each of the teeth (21) of the sprocket wheel (2) is so configured that the distance α between the line (K) connecting the center of two pin holes (52) of the link plate (5) and the center (51c) of inner flanks, and the distance β between the line (K) connecting the center of two pin holes (52)and the top (51d) of a tooth (51) of the link plate (5) satisfy the following formula: 3.5α≤β≤ 3.8α.
(FR) La présente invention concerne une transmission par chaîne silencieuse, capable de réduire l'usure des dents. Ladite transmission par chaîne silencieuse (1) comprend une chaîne silencieuse (3) et une roue dentée (2). Le contour de chacune des dents (21) de la roue dentée (2) est ainsi configuré que la distance α entre la ligne (K) raccordant le centre de deux trous d'axes (52) de la plaque de liaison (5) et le centre (51c) de flancs internes, et la distance β entre la ligne (K) raccordant le centre de deux trous d'axes (52) et le sommet (51d) d'une dent (51) de la plaque de liaison (5) satisfait à la formule suivante : 3,5α ≤ β ≤ 3,8α.
(JA)  歯部の磨耗を抑制することができるサイレントチェーン伝動装置を提供することを課題とする。本発明は、サイレントチェーン(3)とスプロケットホイール(2)とを備えるサイレントチェーン伝動装置(1)であって、リンクプレート(5)のピン孔(52)の中心を結ぶ直線(K)と内股中央部(51c)までの長さαと、リンクプレート(5)のピン孔(52)の中心を結ぶ直線(K)と歯部(51)の先端(51d)までの長さβが、3.5α≦β≦3.8αの関係を満足するように、スプロケットホイール(2)の歯部(21)に、噛合い面を創成する。
