Bearing-slide

Abstract

Abstract 1. Bearing shoe comprising a series of rolling carrier elements (3) which are movable in a support (1) comprising a body with two parallel tracks (2a) called rectilinear or curved bearing tracks, and two return end pieces (9) connecting together two respective ends of the two tracks (2a) so as to form an endless track, the carrier elements (3) being able both to pivot about their axis of symmetry (03) which is parallel to the tracks (2a) and to move perpendicularly to this axis (03), along the endless track (2a) and in which an insert element (4) is placed between two successive rolling carrier elements (3), the ends of these insert elements (4), or these insert elements themselves, being disposed in recesses (5) which form a path (11) for holding the insert elements (4, 13) in position the recesses (5) being formed either in the endless track or else laterally in or on shoulders (2) for lateral guiding of the rolling carrier elements (3), characterized in that the position and the shape of the path (11) holding the insert elements (4) or (13) in position with respect to the endless track (2a) of the rolling carrier elements (3) or conversely, is determined so that the spacing between homologous axes of any two adjacent rolling elements (3) or of any two adjacent insert elements (4, 13), measured along the path of these homologous axes, remains constant ; such an homologous axis being defined by the fact that it is : a) parallel to the contact generatrix lines (A3), said contact being either between each rolling element (3) and the endless track (2a), or between each insert element (4) and its holding path (11) and that it is : b) situated in a plane perpendicular to the endless track (2a) or to the holding path (11) and passing through said contact generatrix line (A3), and that it is : c) situated inside the section of the rolling element (3) or the insert element (4, 13) and that : d) all the homologous axes are at the same distance from the endless track (2a) or from said holding path (11).
