Abstract
(DE)
Lager-Anordnung (51 ) einer Welle (52) eines Handwerkzeugs (2), insbesondere eines Bohrhammers (3), mit einem der Welle (52) zugeordneten Lagerbereich (23), dem zu seiner Schmierung ein mit Schmiermittel (24) gefülltes Schmiermitteldepot (25) zugeordnet ist. Es ist vorgesehen, dass das Schmiermitteldepot (25) mittels mindestens eines Dichtelements (31 , 32) abgedichtet ist.
(EN)
The invention relates to a bearing arrangement (51) of a shaft (52) of a hand tool (2), especially a boring hammer (3), comprising a bearing region (23) which is associated with the shaft (52) and with which a lubricant store (25) filled with lubricant (24) is associated for the lubrication thereof. According to the invention, the lubricant store (25) is sealed by means of at least one sealing element (31, 32).
(FR)
L'invention concerne un système de support (51) d'un arbre d'un outil à main (2), en particulier d'un marteau perforateur (3), comprenant une partie support (23) associée à l'arbre (52), auquel est associé un dépôt de lubrifiant (25) rempli d'un lubrifiant (24) permettant sa lubrification. Selon l'invention, le dépôt de lubrifiant (25) est rendu étanche au moyen d'un élément d'étanchéité (31, 32).
