tooth for attaching to the edge of a bucket of an operating machine, such as an excavator or loader, by means of an adapter, adapter for attaching a tooth to the edge of a bucket of an operating machine, such as an excavator or loader, vehicle and bucket

摘要

The present disclosure relates to a tooth (1) for affixing to the edge of a bucket of an operating machine, such as an excavator or loader, by means of an adapter, the tooth (1) comprising a cavity (103) for receiving a part of said adapter, the cavity (103) extending between said first and second opposing external functional surfaces (12, 14) of an open end (104) at said tooth attachment end to a lower end (105) ; the cavity (103) being delimited by an inner wall (102); said inner wall (102) comprising first and second internally facing inner walls (106, 107), which are the inner surfaces associated with said first outer functional surface and said second outer functional surface (12,14), respectively, and sidewalls. (108) interconnecting said first and second inner walls (106, 107), the cavity defining a rear portion (bp) extending along the y-axis, the rear portion being at least partially located between the covered plane by the x-axis and the open end (104) of the cavity, the front part (fp) extending along the y-axis, the front part being located between the plane covered by the x-axis and the lower end (105) of the cavity; and a stepped portion (sp), which interconnects the rear and the front; at the rear, the first and second inner walls (106, 107) each comprise a pair of essentially planar rear contact surfaces (130a, b; 140a, b) being separated by a rear dividing region (132, 142). ), which extends behind the pair of first contact surfaces. The disclosure also relates to an adapter, and to the coupling between a tooth and an adapter.
