Abstract
A clamping device including a collar which has a belt able to be clamped by the reduction of its diameter and a seal disposed inside the belt by being retained axially relative to the collar. The seal is formed in a strip which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement. The seal undergoes a stress towards the inner surface of the belt and is configured to be elastically deformed against the stress to allow the insertion of an annular object between the seal and the belt.
Claims18
A clamping device comprising a collar which has a belt able to adopt an unclamped state and a clamped state in which a diameter of the belt is reduced compared to the unclamped state, and a seal disposed inside the belt by being retained axially relative to the collar, the seal being formed in a strip, which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement, wherein, in the unclamped state of the belt, the pre-mounted seal disposed inside the belt undergoes a stress towards an inner surface of the belt, the seal being configured to be elastically deformed against said stress to allow the insertion of an annular object between the seal and the belt, the seal having a rear edge which is provided with at least one insertion ramp inclined towards an axis of winding of the strip in a direction moving away axially from the seal from said rear edge, so as to promote insertion of the annular object between the seal and the belt, wherein the seal has a front edge provided with at least one abutment configured to cooperate with a front edge of the belt to retain the seal with respect to a movement in at least one direction relative to the belt and the abutment comprises a lug bent outwardly.
A tube clamping assembly, comprising a clamping device and a tube, the clamping device comprising a collar which has a belt able to adopt an unclamped state and a clamped state in which a diameter of the belt is reduced compared to the unclamped state, and a seal disposed inside the belt by being retained axially relative to the collar, the seal being formed in a strip, which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement, wherein, in the unclamped state of the belt, the pre-mounted seal disposed inside the belt undergoes a stress towards an inner surface of the belt, the seal being configured to be elastically deformed against said stress between a first configuration in which the seal is in contact with an inner surface of the belt, and a second configuration in which the tube is inserted between the seal and the belt and in which the seal is stressed against an inner periphery of the tube.
A tube clamping assembly, comprising a clamping device and a tube, the clamping device comprising a collar which has a belt able to adopt an unclamped state and a clamped state in which a diameter of the belt is reduced compared to the unclamped state, and a seal disposed inside the belt by being retained axially relative to the collar, the seal being formed in a strip, which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement, wherein, in the unclamped state of the belt, the pre-mounted seal disposed inside the belt undergoes a stress towards an inner surface of the belt, the seal being configured to be elastically deformed against said stress to allow the insertion of an end of the tube between the seal and the belt, the assembly comprising a tube position key determining an angular position of the tube relative to at least one of the elements comprising the seal and the collar.
A clamping device comprising a collar which has a belt able to adopt an unclamped state and a clamped state in which a diameter of the belt is reduced compared to the unclamped state, and a seal disposed inside the belt by being retained axially relative to the collar, the seal being formed in a strip, which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement, wherein, in the unclamped state of the belt, the pre-mounted seal disposed inside the belt undergoes a stress towards an inner surface of the belt, the seal being configured to be elastically deformed against said stress to allow the insertion of an annular object between the seal and the belt, the seal having a rear edge which is provided with at least one insertion ramp inclined towards an axis of winding of the strip in a direction moving away axially from the seal from said rear edge, so as to promote insertion of the annular object between the seal and the belt, wherein the insertion ramp is formed by a lug whose free end is bent inwardly.
