Embodiment Construction

[0027] figure 1 A cross-section through a linear guide according to the invention is shown with a guide carriage 1 rolling on a guide rail 2 . The guide carriage 1 comprises a support 3 and an end part 4 (see FIG. 4 ), wherein the end part 4 is fixed on both sides of the support 3 . The support 3 has two guide arms 5 and a connecting web 6 which is integrally connected to the two guide arms 5 , specifically in the form of a U-shaped support. The guide slide 1 is supported on the guide rail 2 by the longitudinal movement of the roller 7 . Rollers 7 are arranged in roller grooves 8 . Each roll groove 8 comprises a support groove 9 supporting the roller 7 , a return groove 10 returning the roller 7 and two turning grooves 11 interconnecting the support groove 9 and the return groove 10 . The roller groove 8 has guide rails 12 , 13 , 14 , 15 , 16 , 17 for the rollers 7 . The guide rail 12 is formed on the guide rail 2 . Two such guide rails 12 are arranged on each longitudina...

Abstract

The invention relates to a linear roller bearing comprising a guiding carriage (1) which can be mounted on a guiding rail (2) by means of rolls (7) and comprises at least one continuous roll channel (8) for the rolls (7). Said roll channel (8) comprises a carrier channel (9) for carrying rolls (7), a return channel (10) for returning rolls (7), and two deviation channels (11) which interconnect the carrier channel (9) and the return channel (10). The guiding carriage (1) comprises a carrier body (3) containing the return channel (10) and the carrier channel (9), and end parts (4) which contain the deviation channels (11) and are arranged on both front sides of the carrier body (3). The return channel (7) comprises a return pipe (11), the ends of said pipe being connected to the end parts (10). The roll channel comprises tracks for the rolls and lateral surfaces for laterally defining the roll channel. The return pipe (11) is provided with tongues (33) which engage in the end part (4), the facing tongue surfaces (34) forming the lateral surfaces (22) of the deviation channel (11). A separation joint (37) is arranged between each tongue (33) and the end limb (4) at least parallel to the return pipe (11).

Description

technical field [0001] The invention relates to linear rolling bearings used, for example, in linear guides for machine tools. The invention relates in particular to such a linear rolling bearing, through which both forces and torques are transmitted transversely to the guiding direction. Background technique [0002] DE 41 38 026 A1 discloses a linear rolling bearing with a guide carriage which can be mounted rolling on a guide rail via rollers. The guide carriage has at least one annular roller groove for the rollers. The roller trough includes a support trough for supporting the roll, a return trough for the return roll and two turning troughs connecting the support trough and the return trough to each other. The guide slide includes a return groove and a support having a support groove and an end piece provided on both end faces of the support having turning grooves. The return trough includes a return tube, the tube end of which is connected to the end piece. The ro...
