Patent

CA 2530245

This invention concerns a rolling screw with smaller advance per turn than the pitch of the threading, characterised in that a threaded coupling is foreseen in which a screw (1) is turned inside one or more female screws inserted in a single body or sleeve (2) and where the pitch of the thread of said female screws is equal to that of the screw (1), whereas the nominal diameter is greater than that of the screw itself.

L'invention se rapporte à une vis à billes présentant une vitesse inférieure par tour à celle du pas du filetage. Elle se caractérise par le fait qu'un raccord fileté est prévisible, une vis étant tournée à l'intérieur d'au moins une vis femelle insérée dans un seul corps ou manchon, et le pas du filet des vis femelles étant égal à celui de la vis, le diamètre nominal étant en revanche supérieur à celui de la vis elle-même.
