Abstract: The invention relates to a method of fixing a wear element (2) on the front edge of a support (1) using fixing means, where the wear element (2) comprises two arms (3) with first through openings (4) and the support (1) has a second through opening (5) sandwiched between the first through openings (4). The fixing means comprise a C-shaped first body (6), a wedge (14), ratchet means (24) between both and a second body (8), which are housed in the openings in an assembled position. The method consists of positioning the first body (6) and the second body (8) in the openings, inserting the wedge (14) between both, positioning a screw (21) between the wedge (14) and the second body (8) and screwing it in such a way that the wedge (14) moves with respect to the second body (8) and the first body (6) until the wedge (14) reaches its assembled position, and at least partially unscrewing the screw (21) and removing the screw (21) from the fixing means.

Abstract: A wear element configured to be fixed on a support, where the wear element comprises two arms wrapping around the front edge of the support. The wear element being fixed with [a] a C-shaped body, [b] a wedge, [c] a screw with a shank, with a first segment having a smaller diameter than the head, a second segment having a larger diameter than the first segment, and a threaded segment, and [d] a nut. The shank of the screw is housed between the wedge and the body. The C-shaped body has a C-shaped projection suitable for housing the first segment of the screw. The projection has substantially the same height as the first segment. Neither the head nor the second segment can go through the projection. The wedge has a first projection and a second projection. Both projections have through holes suitable for allowing the passage of the threaded segment and suitable for blocking the passage of the nut, and the distance between both projection is greater than the height of the nut.

Abstract: 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 (12, 14) from an open end (104) to a bottom end (105); the cavity (103) delimited by an inner wall (102) having first and second facing inner walls (106, 107), and opposing side walls (108), interconnecting the first and second inner walls (106, 107). 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.

Abstract: The present invention relates to a fixing device for fixing a wear or protection element on a bucket of an earth moving machine, comprising: a base with a housing with a front wall and a rear wall with a through hole, a stop with a lower part housed in the housing, a screw having a head going through the hole and having an end thereof fixed to the stop and a partially compressed elastic device arranged between the screw and the hole. When the elastic device is fully compressed it has a length of L0. In a mounted position, the stop has a front face opposite the front wall, where the distance between both is D1 and the distance between the head and the hole has a value of D2, and the condition of D2?L0>D1 is met in the mounted position.

Abstract: The present disclosure relates to a tooth (1) for attachment to the lip of a bucket of a working machine, such as an excavator or loader, via an adaptor, the tooth (1) comprising a cavity (103) for receiving a portion of said adaptor, the cavity (103) extending between said first and second opposed outer working surfaces (12, 14) from an open end (104), at said attachment end of the tooth, to a bottom 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), being the internal surfaces associated with said first outer working surface and said second working outer surface (12,14), respectively, and opposing side walls (108), interconnecting said first and second inner walls (106, 107), the cavity defining a back portion (BP) extending along the Y axis, the back portion being at least partially located between the plane spanned by the X and Z axis and the open end (104) of the cavity, a front portion (FP) exte

Abstract: A retaining device, a retaining system between a female part and a male part, and a female part and male part to assure retention between a wear element or tooth and an adaptor element or tooth bar used in excavators and the like. The female part, which can be a wear element or tooth, or an adaptor element or tooth bar, has, auto-fixed thereto, a retaining device which participates in the coupling with a pin of the female part with a male part, and prevents the pin from coming out of its blocking position, maintaining the fixing between the two parts, i.e., male part and female part. The coupling between both parts is detachable, allows removing the pin from the coupling and replacing the female part or male part together with the retaining device. The retaining device is formed by one or more attached tightening elements.
