Abstract
A device for fitting two components together by a clevis is improved by a seal including a deformable ring subjected to axial compression between one of the cheeks and a mobile washer which is brought closer to the cheek when a bolt passing through the clevis is tightened. This axial compression causes the rod to be clamped by the seal, eliminating all play and giving the assembly good cohesion while at the same time eliminating the transmission of vibration and noise.
Claims28
A connecting device between a first component, bearing a clevis with two cheeks having aligned piercings, and a second component with coupling having a piercing, the connecting device comprising, in a connection mounting state, a bolt, of which a rod passes through piercings of the cheeks and the piercing of an end aligned between the piercings of the cheeks in an axial direction, the bolt being tightened on either side of the cheeks;
- and the device being wherein:
- a washer, on which the bolt bears, penetrates into the piercing of the first of the cheeks;
- and the device comprising an annular seal which, in the connection mounting state, is fixed in the piercing of the coupling, the seal comprising a deformable ring with a hole that is passed through by the rod of the bolt, a main portion being tightened radially against the rod of the bolt and tightened axially between the washer and a second of the cheeks in the mounting state.
A connecting assembly comprising a spacer with two opposing ends, in which the spacer comprises, at at least one of the ends, a clevis with two parallel cheeks having piercings that are aligned in an axial direction;
- wherein the assembly also comprises:
- an annular seal which comprises a deformable ring having a hole;
- a bolt with a rod that can pass through the hole of the ring and the piercings of the cheeks;
- a washer that can penetrate into the piercing of the first of the cheeks and on which the bolt can bear;
- the ring having a first axial end of smaller radius than the piercing of the first of the cheeks, and a second axial end of greater radius than the piercing of the second of the cheeks.
