Embodiment Construction

[0021] The linear rolling bearing according to the invention can be produced in that the carriage running surface formed integrally on the main body in the linear rolling bearing known from DE 10 2007 056 862 is replaced by a running surface component with a carriage running surface described below. DE 10 2007 056 862 is therefore cited in full and forms the content of the present application.

[0022] figure 1 A roughly schematic cross-section through a linear rolling bearing 10 according to the invention is shown. The linear rolling bearing 10 comprises a guide rail 11 made of hardened rolling bearing steel extending in a longitudinal direction 12 , wherein the longitudinal direction 12 is oriented perpendicular to the plane of the drawing. The guide rail 11 has a substantially constant cross-sectional shape over its entire longitudinal extent, a total of four flat rail running surfaces 14 being provided for the substantially cylindrical rolling bodies 13 .

Abstract

The invention relates to a guiding slide carriage (30) of linear rolling bearing (10). The guiding slide carriage can be supported a guiding rail (11) extended in the longitudinal direction (12) in a longitudinally movable way by a plurality of rolling bodies (13); wherein, the guiding slide carriage (30) comprises at least one rolling surface component (32); the rolling surface component has at least one slide carriage rolling surface (36) used for the rolling body (13); wherein, the rolling surface component (32) is fixed on the main body (31) of the guiding slide carriage (30) by at least one adhesive layer (33). According to the present invention, a thin plate (50) having at least one through hole is disposed between the rolling surface component (32) and the main body (31); and the adhesive layer is disposed in the through hole.

Description

technical field [0001] The invention relates to a guide carriage for a linear rolling bearing. Linear rolling bearings in the sense of the invention are, for example, ball and roller rail guides, spherical bushings and ball splines. Background technique [0002] DE 20 2004 002 258 U1 discloses a linear rolling bearing in the form of a cross roller guide. According to DE20 2004 002 258 U1 figure 1 , the linear rolling bearing comprises a guide rail 3 extending in the longitudinal direction, on which a U-shaped guide carriage 4 is longitudinally displaceably supported via a plurality of roller-shaped rolling elements 11 . According to DE20 2004 002 258 U1 figure 2 , a special rolling surface part 21 is provided in the guide slide, with the slide rolling surfaces 8, 9 for the rolling bodies. According to DE 20 2004 002 258 U1 Figure 4 a, An adhesive layer 39a, 39b is arranged between the rolling surface parts and the guide carriage body for fixedly connecting the parts t...
