RETENTION PIN AND METHOD OF FORMING

A retention pin assembly (50) may include a stud (72) having a head (76), a shaft (74), and a deformable end (78). The shaft (74) may include a stepped surface having a greater diameter than the deformable end (78). The assembly may include a support member (66) having an opening for receiving the d...

description A retention pin assembly (50) may include a stud (72) having a head (76), a shaft (74), and a deformable end (78). The shaft (74) may include a stepped surface having a greater diameter than the deformable end (78). The assembly may include a support member (66) having an opening for receiving the deformable end (78). The support member (66) may include a pocket (80). The stepped surface of the shaft (74) may position the stud (72) in relation to the support member (66). The deformable end (78) of the stud (72) may be operable to be melted to form a mechanical retainer within the pocket (80) without forming a metallurgical joint between the stud (72) and the pocket (80). A leaf seal assembly comprising such a retention pin, and a corresponding method of forming a joint. La présente invention se rapporte à un ensemble broche de retenue qui peut comprendre un goujon qui comporte une tête, un axe et une extrémité déformable. L'axe peut comporter une surface étagée qui présente un diamètre plus important que celui de l'extrémité déformable. L'ensemble peut comprendre un élément de support qui comporte une ouverture destinée à recevoir l'extrémité déformable. L'élément de support peut comprendre une poche. La surface étagée de l'axe peut positionner le goujon par rapport à l'élément de support. L'extrémité déformable du goujon peut être utilisée pour être fondue afin de former un dispositif de retenue mécanique dans la poche sans former de joint métallurgique entre le goujon et la poche.
