Abstract
The present disclosure provides sealing devices and construction methods thereof. The sealing devices include a duct having a main axial portion, an intermediate annular portion facing the main axial portion, and an annular end portion facing the intermediate annular portion. The intermediate annular portion and the end annular portion are connected by an annular fold so as to form an axial annular mounting slot that is axially open opposite this annular fold. A connecting member comprises a radial plateau and, around a through-opening, an axial annular mounting portion. The axial annular mounting portion of the connection member is engaged and grasped in the axial mounting slot between the intermediate annular portion and the end annular portion of the duct.
Claims17
A sealing device, comprising:
- a duct;
- and
- a link member secured to the duct;
- wherein the duct comprises:
- a main axial portion;
- an intermediate annular portion facing an end annular part of the main axial portion;
- a terminal annular portion facing the intermediate annular portion, the terminal annular portion being situated radially inside the intermediate annular portion, or the intermediate annular portion being situated radially inside the terminal annular portion, the intermediate annular portion and the terminal annular portion being linked by an annular fold to form an axial annular mounting slit that is open axially opposite the annular fold and opposite another end annular part of the main axial portion, the intermediate annular portion extending between the end annular part of the main axial portion and the terminal annular portion;
- wherein the link member comprises a radial flange plate and, around a through-opening, an axial annular mounting portion, the radial flange plate and the axial annular mounting portion being linked by a second annular fold;
- wherein the axial annular mounting portion of the link member is engaged axially and gripped radially, over at least one annular zone, in the annular mounting slit between the intermediate annular portion and the terminal annular portion of the duct, and
- wherein the main axial portion, the intermediate annular portion of the duct, the axial annular mounting portion of the link member and the terminal axial portion of the duct have annular ridges engaged in one another.
The sealing device as claimed in 1, wherein the intermediate portion is linked to the main axial portion by a third annular fold.
A method for manufacturing a sealing device comprising a duct and a link member, the link member comprising a radial flange plate and an axial annular mounting portion, the method comprising:
- folding an end annular part of the duct, to obtain an axial annular mounting slit that is open axially outward, between an intermediate annular portion linked to a main axial portion a first annular fold and a terminal annular portion linked to the intermediate annular portion a second annular fold;
- axially engaging the axial annular mounting portion of the link member inside the annular mounting slit;
- and
- radially compressing the axial annular mounting portion of the link member, over at least one annular zone, between the intermediate annular portion and the terminal annular portion of the duct.
A method for manufacturing a sealing device comprising a duct and a link member, the link member comprising a radial flange plate and an axial annular mounting portion, the method comprising:
- producing a preform comprising at least one intermediate annular portion and a terminal annular portion linked by an annular fold and forming between the at least one intermediate annular portion and the terminal annular portion an annular mounting slit;
- mounting the preform on an end annular part of the duct, in a position such that the intermediate annular portion is situated between the end annular part of the duct and the terminal annular portion, and mounting the axial annular mounting portion of the link member in the annular mounting slit;
- and
- radially compressing the axial annular mounting portion of the link member, over at least one annular zone, between the at least one intermediate annular portion and the terminal annular portion.
