The present invention relates to a novel arrangement for attaching, by screw threads, one device to another wherein the one device has a greater thermal rate of expansion than the other and the devices are assembled at a temperature which is lower than that at which the two devices are regularly subjected. In particular, the novel arrangement maintains the security of the attachment where the differing thermal rates of expansion would normally cause the screw thread attachment to become loose.
La présente invention se rapporte à un nouvel agencement permettant d'attacher, par des filets de vis, un dispositif à un autre, l'un de ces dispositifs possédant un taux de dilatation thermique supérieur à celui de l'autre dispositif, et les deux dispositifs étant assemblés à une température qui est inférieure à celle à laquelle ces dispositifs sont soumis habituellement. Ce nouvel agencement permet notamment d'assurer la sécurité de la fixation dans des conditions où les taux de dilatation thermique différents provoqueraient normalement un relâchement de la fixation par filets de vis.
