Title (EN) DUAL LIP SEAL AND METHOD OF FORMING THE SEAL
(FR) JOINT D'ETANCHEITE A DEUX LEVRES ET PROCEDE DE PRODUCTION DU JOINT
Abstract: front page image
(EN)A dual lip shaft seal includes two sealing disks (49-50) bonded directly to a radial wall (41) of an annular metal case (37). The radial wall (41) has an annular step (43), such that two separate mounting surfaces (45-47) are formed for mounting the two disks (49-50). Each sealing disk (49-50) is preferably formed of PTFE and heat-bonded to its respective mounting surface (45-47) by an induction heater coil (53) disposed in confronting relation to the radial wall (41) of the metal case (37).
(FR)Un joint d'étanchéité à deux lèvres pour un arbre comprend deux disques d'étanchéité (49-50) directement fixés à une paroi radiale (41) d'une enveloppe métallique annulaire (37). La paroi radiale (41) comprend un épaulement annulaire (43) formant deux surfaces de montage séparées (45-47) permettant de monter les deux disques (49-50). Chaque disque d'étanchéité (49-50) est de préférence composé de PTPE et est thermo-collé à sa surface de montage respective (45-47) par une bobine de chauffage à induction (53), placée de manière opposée à la paroi radiale (41) de l'enveloppe métallique (37).
