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

Method of fixing a wear element on the front edge of a support and corresponding fixing means

Excavator bucket tooth

Excavator bucket tooth adapter

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.

Fixing means for fixing a wear element on the front edge of a support

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 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 L. In a mounted position, the stop has a front face opposite the front wall, where the distance between both is Dand the distance between the head and the hole has a value of D, and the condition of D&#x2212;L&#x3e;Dis met in the mounted position.

Fixing device for fixing a wear or protection element on a bucket of an earth moving machine and corresponding fixing method and wear or protection system

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.

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.

Retention device for male and female components in excavator machines

Device for detachable fastening of two mechanical components between which a channel or housing is defined, including a peg, with at least two grooves on opposite faces, and a band accommodated in the grooves, fastened by pinching at the lower part of the peg and with a flexible portion that has the upper end thereof bent in order to retain the peg/band assembly in a transverse grove of the channel The invention applies in particular to the fastening of a tooth in a tooth holder of the scoop of an excavating machine or the like.

Device for detachable fastening of two mechanical components

The invention relates to a retaining device, a retaining system between a female part and a male part, and a female part and male part to assure the 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, comprises, 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. Said retaining device is formed by one or more attached tightening elements

A coupling system for coupling a wear element to an adapter for excavators and similar machinery and the components thereof. The coupling system is formed by a wear element, preferably a tooth though possibly a bucket protection element, a tooth bar or adaptor element and a securing system for securing the two elements, formed mainly by a pin. In addition, the securing system can include a retaining element with resilient properties, associated with the pin.
