A tooth for attachment to the lip of a bucket of a working machine via an adaptor, having a cavity for receiving a portion of the adaptor, the cavity extending between first and second opposed outer working surfaces () from an open end () to a bottom end (); the cavity () delimited by an inner wall () having first and second facing inner walls (), and opposing side walls (), interconnecting the first and second inner walls (). The cavity defines a back portion (BP) along the Y axis and between the plane spanned by the X and Z axes and the open end of the cavity, a front portion (FP) along the Y axis and between the plane spanned by the X and Z axes and the bottom end of the cavity; and a stepped portion (SP), interconnecting the back portion and the front portion.

Tooth and adaptor for attachment of the tooth to a working machine

The present disclosure relates to a tooth () for attachment to the lip of a bucket of a working machine, such as an excavator or loader, via an adaptor, the tooth () comprising The disclosure also relates to an adaptor, and to the coupling between a tooth and an adaptor.

The device is characterized in that the nose of the tooth-carrier has a general structure in which two end regions thereof, one corresponding to the area of junction of the said nose with the body of the tooth-carrier and the other to the free end of the tooth-carrier, assume in cross-section a dovetail structure, the dovetail at the first end region being inverted compared to the dovetail at the second end region, the cross-section of the end projection of the nose of the tooth-carrier being constant and the upper face of junction of the said projection with the base of the tooth-carrier assuming a curved structure with the convexity directed outwards, the lateral faces of the nose of the tooth-carrier assuming a structure of flat facets, one of them carrying in proximity to the junction with the body of the tooth-carrier a substantially vertical indentation for the coupling of the retaining cotter pin.

Device for the coupling of excavator teeth

The device is characterized by the coupling protuberance of the tooth in a zone which is adjacent to the base of the tooth and is comprised of side faces which are both inclined from said base towards the axis of the piece and from the lower edge inwardly, and also presenting an upper face inclined from top to bottom and a lower planar face, continued into a second zone which presents additionally planar faces extending from the lower edges of the protuberance and showing an inward inclination; the coupling protuberance is terminated by a posture section of which the side faces extend from an upper planar face which is parallel to the piece axis, and inclined inwardly and joining a unique lower face which is also planar and parallel to the piece axis and terminated at the planar extremity of the protuberance which is perpendicular to the piece axis.
