Title (EN) TAPER PULLEY
(FR) POULIE CONIQUE
(JA) テーパプーリ
Abstract:
(EN) Provided is a taper pulley whereby a belt can be appropriately conveyed while preventing friction even in a low-temperature environment. A rubber part (22) that is the outer peripheral face of a pulley (11) is divided, in the axial direction, into a plurality of areas (A1), (A2) and (A3).  The hardness (H-30°C) at -30°C of the areas (A1) and (A3) is higher than the hardness (H-30°C) at -30°C of the area (A2).  The areas (A1) and (A3) comprise a highly hardwearing rubber such as NBR.  The area (A2) comprises a highly cold-proof rubber such as SBR or BR.  These highly cold-proof rubbers show a small increase in hardness with a lowering in temperature from room temperature (23°C) to a low temperature (-30°C).
(FR) La présente invention se rapporte à une poulie conique, une courroie pouvant être acheminée de manière appropriée tout en empêchant le frottement même dans un environnement à faible température. Une partie caoutchouc (22) qui est la face périphérique extérieure d’une poulie (11) est divisée, dans la direction axiale, en une pluralité de zones (A1), (A2) et (A3). La dureté (H-30°C) à -30°C des zones (A1) et (A3) est supérieure à la dureté (H-30°C) à -30°C de la zone (A2). Les zones (A1) et (A3) comprennent un caoutchouc ayant une résistance à l’usure très élevée tel que le NBR. La zone (A2) comprend un caoutchouc ayant une résistance au froid très élevée tel que le SBR ou BR. Ces caoutchoucs ayant une résistance au froid très élevée présentent une petite augmentation de dureté lorsque la température diminue, passant de la température ambiante (23°C) à une basse température (-30°C).
(JA)  低温環境下でも、摩擦の発生を抑制しつつ、ベルトを適切に運転可能なテーパプーリを提供する。 プーリ11の外周面であるゴム部22は、軸方向に複数の領域A1、A2、A3に分割される。領域A1、A3の-30℃における硬度H-30℃は、領域A2の-30℃における硬度H-30℃より高い。領域A1、A3は、NBR等の耐摩耗性の高いゴムで形成される。領域A2は、SBR、BR等の耐寒性の高いゴムで形成される。これら耐寒性の高いゴムは、常温(23℃)から低温(-30℃)に下げたときの硬度上昇率が低い。
