摘要：
An assembly for mounting an excavating tooth (30) particularly suited for a dredge cutterhead includes a base (52), an adapter (34), and a lock (36). The base (32) includes a convex, curved bearing surface that abuts a concave, curved bearing surface on the adapter. The curved bearing surfaces are able to maintain substantially full contact with each other under transverse loading.
