Abstract (en)
Assembly of a tooth (3) and an adapter (1) for application with an excavator, such as e.g. a cutter. The parts have telescoping elements (4 and 2, respectively) with tapering surfaces. Recesses (11, 12) for receiving a locking element (10) are made in two abutting surfaces. At least one of said two abutting surfaces (5, 7) of the tooth (3) and/or the adapter (1) has a curved surface as seen transverse to the sliding direction of the parts. Both abutting surfaces (5, 7) can be of curved design with the centres (6, 8, resp.) of the radii of curvature (R, S, resp.) are at the same side of the abutting surfaces and one radius of curvature (S) being larger than the other (R) so that initially the surfaces contact each other according to a line (9). <IMAGE>
