Claims (7)

1. Linearlager (1), bestehend aus
  • - einem ortsfesten Teil (2) und
  • - einem relativ zum ortsfesten Teil (2) in eine Verschieberichtung (L) linear verschiebbaren beweglichen Teil (3),
wobei in den Teilen (2, 3) jeweils mindestens eine Führungsfläche (4, 5) angeordnet ist die zur Anlage von Wälzelementen (6), insbesondere Kugeln, dient
wobei die Wälzelemente (6) die beiden Teile (2, 3) in einer Wirkrichtung (R) gegeneinander abstützen, die senkrecht zur Verschieberichtung (L) verläuft, und
wobei beide Teile (2, 3) zur Einstellung des Spiels zwischen den Führungsflächen (4, 5) und den Wälzelementen (6) relativ zueinander in Wirkrichtung (R) gegeneinander festlegbar sind,
dadurch gekennzeichnet, dass an mindestens einem Teil (2, 3) formschlüssig zusammenwirkende Mittel (7) angeordnet sind, die eine stufenweise Verstellung der beiden Teile (2, 3) in Wirkrichtung (R) relativ zueinander zulassen.1. Linear bearing ( 1 ) consisting of
  • - A fixed part ( 2 ) and
  • - a movable part ( 3 ) which is linearly displaceable relative to the stationary part ( 2 ) in a displacement direction (L),
at least one guide surface ( 4 , 5 ) is arranged in each of the parts ( 2 , 3 ) and is used for bearing rolling elements ( 6 ), in particular balls
wherein the rolling elements ( 6 ) support the two parts ( 2 , 3 ) against each other in an effective direction (R) which is perpendicular to the direction of displacement (L), and
The two parts ( 2 , 3 ) for setting the play between the guide surfaces ( 4 , 5 ) and the rolling elements ( 6 ) can be fixed relative to one another in the effective direction (R),
characterized in that on at least one part ( 2 , 3 ) positively cooperating means ( 7 ) are arranged, which allow a gradual adjustment of the two parts ( 2 , 3 ) in the effective direction (R) relative to each other. 2. Linearlager nach Anspruch 1, dadurch gekennzeichnet dass die formschlüssig zusammenwirkenden Mittel (7) aus einer Verzahnung bestehen.2. Linear bearing according to claim 1, characterized in that the positively cooperating means ( 7 ) consist of a toothing. 3. Linearlager nach Anspruch 2, dadurch gekennzeichnet, dass die einzelnen Zähne des Verzahnungsprofils (7) in die lineare Verschieberichtung (L) verlaufen.3. Linear bearing according to claim 2, characterized in that the individual teeth of the tooth profile ( 7 ) extend in the linear direction of displacement (L). 4. Linearlager nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass mindestens eines der Teile (2, 3) im Querschnitt im wesentlichen rahmenförmig ausgebildet ist.4. Linear bearing according to one of claims 1 to 3, characterized in that at least one of the parts ( 2 , 3 ) is substantially frame-shaped in cross section. 5. Linearlager nach Anspruch 4, dadurch gekennzeichnet, dass das rahmenförmig ausgebildete Teil (2, 3) aus zwei im wesentlichen U-förmigen Abschnitten (2', 2", 3', 3") besteht.5. Linear bearing according to claim 4, characterized in that the frame-shaped part ( 2 , 3 ) consists of two substantially U-shaped sections ( 2 ', 2 ", 3 ', 3 "). 6. Linearlager nach einem der Ansprüche 2 bis 5, dadurch gekennzeichnet, dass die formschlüssig zusammenwirkenden Mittel (7) aus einem sich linear in Wirkrichtung (R) erstreckenden, im Querschnitt im wesentlichen fingerförmig ausgebildeten Abschnitt (8) und aus einem sich linear in Wirkrichtung (R) erstreckenden, im Querschnitt im wesentlichen gabelförmig ausgebildeten Abschnitt (9) bestehen, wobei beide Abschnitte (8, 9) im Innenbereich der Gabel an den sich gegenüberliegenden Flächen mit der Verzahnung (10) versehen sind. 6. Linear bearing according to one of claims 2 to 5, characterized in that the form-fitting interacting means ( 7 ) from a linearly extending in the direction of action (R), cross-sectionally finger-shaped section ( 8 ) and from a linearly in the direction of action (R) extending section ( 9 ) which is essentially fork-shaped in cross section, both sections ( 8 , 9 ) being provided with the toothing ( 10 ) on the opposite surfaces in the inner region of the fork. 7. Linearlager nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet dass eines der Teile (2) das andere Teil (3) zumindest teilweise umschließt.7. Linear bearing according to one of claims 1 to 6, characterized in that one of the parts ( 2 ) at least partially surrounds the other part ( 3 ).
