(FR) GALET TENDEUR DE CHAINE
Abstract:
(EN) The present invention relates to a chain idler of guide bar on chain sawing device having a hub (2) and a cage (3). There are grooves or hollows (6) on the rotating cage (3) which catch lubricating oil and transport the same, driven by the rotation movement, towards the hub (2) to effectively lubricate a bearing and the sides of the cage (3).
(FR) La présente invention se rapporte à un galet tendeur de chaîne d'une glissière de guidage sur une tronçonneuse, comprenant un moyeu (2) et une cage (3). Des rainures ou des creux (6) se trouvant sur la cage rotative (3) saisissent de l'huile lubrifiante et la transportent, entraînée par le mouvement de rotation, vers le moyeu (2) afin de lubrifier efficacement un palier et les côtés de la cage (3).
