CA 2108307
Strips of polytetrafluoroethylene (i.e., Teflon) are interposed, equally spaced apart, between the journal and sleeve, and journal and collar of a bearing assembly to provide lubrication thereat. The Teflon strips are fibrous and porous, and compressibly collapsible therefor, to insure that thermal expansion of any one thereof will not unduly load the bearing assembly. The bearing material has surface voids in which to trap and retain the Teflon which is wiped onto the contact surfaces.
Des bandes de polytétrafluoréthylène (Téflon) sont interposées, en espacement régulier, entre un tourillon et un coussinet-douille et entre un tourillon et les joues d'un palier aux fins de lubrification de l'ensemble de support. Les bandes de Téflon sont fibreuses, poreuses et donc compressibles, ce qui assure une protection contre les risques de surcharge du palier sous l'effet de la dilatation thermique. L'antifriction utilisé comporte des vides de surface servant à capter et à retenir les particules de Téflon laissées sur les surfaces de contact.
