Title
(EN) REPLACEABLE ADAPTER FOR EXCAVATING CUTTERHEAD
(FR) ADAPTATEUR REMPLAÇABLE POUR TETE DE TREPAN D'EXCAVATION
Abstract
(EN)
An adapter assembly (27, 29, 41) for an excavating cutterhead (20) including a combination of a blade socket (27) with a hemispherical recess (28), an adapter (29) with a hemispherical bottom (31) on shank (30) to fit in the socket (27), and a mounting ring (41) around the adapter shank (30) opposite to bottom (31) which can be indexed with respect to each other such that the adapter (29) may be precisely replaced in an operating assembly without need to reorient the entire assembly (27, 29, 41). Mutually indexing (44, 45) of each of the adapter (29) and the mounting ring (41) prior to the initial orientation of the assembly (27, 29, 41) permits replacement of the adapter (29) without use of the normal profile board. The adapter (29) supports a removable and replaceable tooth (33) in proper orientation on the cutterhead (20).
(FR)
L'invention concerne un ensemble adaptateur (27, 29, 41) destiné à une tête de trépan d'excavation (20), et qui comprend une combinaison d'une douille de lame (27) comportant une encoche hémisphérique (28), d'un adaptateur (29) comportant un fond hémisphérique (31) sur la tige (30) destinée à entrer dans la douille (27), et d'une bague de fixation (41) entourant la tige de l'adaptateur (30) opposée au fond (31). On peut étalonner la bague de fixation par rapport à la tige, de façon à pouvoir replacer avec précision l'adaptateur (29) dans un ensemble fonctionnel sans avoir besoin de réorienter la totalité de l'ensemble (27, 29, 41). En étalonnant mutuellement (44, 45) l'adaptateur (29) et la bague de fixation (41) avant l'orientation initiale de l'ensemble (27, 29, 41), on peut remplacer d'adaptateur (29) sans utiliser le gabarit normal. L'adaptateur (29) porte une dent amovible et remplaçable (33) orientée de manière convenable sur la tête (20).
