摘要： A wear member comprising a front end and a rear end. The rear end having a cavity formed therein, the cavity having rear portion and a forward portion, the rear portion having a cross-sectional width and a cross-sectional height, the cross-sectional width being different than the cross-sectional height, the rear portion of the cavity having two surfaces horizontal in cross-section and angled toward a longitudinal axis of the cavity and four substantially planar surfaces, the four substantially planar surfaces being oblique in cross-section. A first two of the four substantially planar surfaces is disposed on a first lateral side of the two surfaces horizontal in cross-section, and a second two of the four substantially planar surfaces is disposed on a second lateral side of the two surfaces horizontal in cross-section. In the rear portion, the cross-sectional width of either of the two surfaces horizontal in cross-section is different than the cross-sectional width of any one of the four substantially planar surfaces; and an intermediate portion disposed between the rear portion and the forward portion, the intermediate portion comprising a different number of surfaces in cross-section than a number of surfaces of the rear portion and the forward portion in cross-section.

摘要： A wear member assembly comprising an adapter nose having a longitudinal axis. The adapter nose comprising a forward portion having a plurality of outwardly facing surfaces angled with respect to the longitudinal axis of the nose at a first angle, the outwardly facing surfaces of the forward portion being oblique in cross-section. The adapter nose comprising an intermediate portion having a plurality of outwardly facing surfaces angled with respect to the longitudinal axis of the nose at a second angle different than the first angle, the outwardly facing surfaces of the intermediate portion being oblique in cross-section. The adapter nose comprising a rear portion having a plurality of outwardly facing surfaces angled with respect to the longitudinal axis of the nose at a third angle different than the second angle, the outwardly facing surfaces of the rear portion being oblique in cross-section. A plurality of the surfaces being oblique in cross-section being shaped and sized as bearing surfaces to bear against a wear member fit over the adapter nose.

摘要： The tooth and adaptor for dredging machines object of the present invention relates to a tooth which, attached to an adaptor, creates an assembly the purpose of which is to deepen and clean the beds of ports, rivers, channels, etc., removing therefrom sludge, stones, sand, etc., the adaptors being attached to the blades thus forming the cutter head of the dredging machine. The constructive features of the coupling between the tooth and the adaptor allow a great stability between both elements, among other advantages.
