Retention device for male and female components in excavator machines

摘要

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

主权项

1. A retaining device for a male part with an orifice or for a female part with an orifice which are to be coupled to one another, the retaining device comprises at least one tightening element to allow auto-fixing of the retaining device by pressure directly to a surface of the female part or of the male part, said tightening element comprising:
two straight sectors attached to one another by an intermediate third sector, and wherein at least one of the two straight sectors has a split or bifurcation thus forming two sub-sectors approximately parallel to one another so as to press against a common interior side of the female part or the male part so that each of the two subsectors engages an opposite side of a pin when inserted in the orifice of the female part or the orifice of the male part; and wherein the male part and the female part are for a tooth assembly of an excavator.
