Definitions

  • Cylindrical roller bearing or needle roller bearing executed.
  • German Patent Application DE 19726726 A1 can be mentioned here. While the cited patent publication still shows an axial stop in the drive bearing, which avoids an axial sliding out of the cylindrical roller bearing, it was found that pushed out in modified versions with a smooth continuous cylindrical bore in the drive bearing for receiving the cylindrical roller bearing in rare cases this camp from the drive end plate can be. This pushing out is caused by acting between the drive shaft and the rolling friction when pushing out the drive shaft.

Abstract

L'invention concerne un dispositif de démarrage destiné à des moteurs à combustion interne et comprenant un palier d'entraînement (11) et un arbre d'entraînement (14), l'arbre d'entraînement (14) dans le palier d'entraînement (11) étant supporté par un palier à roulement (13). Le palier à roulement (13) permet un mouvement relatif à parts rectilignes et rotatives entre l'arbre d'entraînement (14) et le palier à roulement (13). Le dispositif de démarrage selon l'invention est caractérisé en ce que le palier à roulement (13) possède une bague externe (30) qui est bloquée dans le palier d'entraînement (11) et qui présente une butée (33) empêchant un déplacement du palier à roulement (13) hors du palier d'entraînement (11).
