COUPLING SYSTEM OF A SEALING ASSEMBLY WITH A ROTATING ANNULAR ELEMENT

摘要

Coupling system of a sealing assembly that has an annular rotating element, the seal assembly provides an annular screen providing a sleeve portion to be integrally coupled with the annular element rotating and a flange portion that protrudes radially from the sleeve portion. The sleeve portion by coupling with a seat mounting of the annular rotating element defined by an outer cylindrical surface of the mounting and including a first circumferential discontinuity cooperating with the sleeve portion to locally increase a reaction force of the cylindrical surface at the first circumferential discontinuity due to elastic radial pressure exerted by the sleeve portion on the mounting seat.

1. A coupling system for a sealing unit, the coupling system comprising:
an annular rotating member, and the sealing unit providing;
an annular shield provided with a tubular portion that is coupled with the annular rotating member, anda flanged portion that radially protrudes cantilevered from the tubular portion; whereinthe tubular portion is coupled with a mounting seat of the rotating member and is bordered by a mounting cylindrical external surface that provides a first circumferential discontinuity that cooperates with the tubular portion in order to increase locally in correspondence to the same first circumferential discontinuity a reaction force of the mounting cylindrical external surface; the reaction force being due to a radial elastic pressure exercised by the tubular portion against the mounting seat.
