Embodiment Construction

[0041] figure 1 A non-circular rolling body 1 is shown, which can be used in a linear rolling bearing. The rolling body 1 is based on the basic shape of a ball and has two parallel flats 2 which lie opposite each other and are perpendicularly passed through by a rolling axis 3 .

[0042] figure 2 The shift lock 4 is shown in section. The shift lock 4 includes a housing 5 in which a locking pin 6 can be axially displaced. The locking pin 6 is mounted in the housing 5 by means of a linear roller bearing 7 . exist image 3 The linear rolling bearing 7 shown in section along the line III-III in , consists of two rows of rolling bodies 1 with a flattened portion 2 .

[0043] Such as image 3 As shown in , the linear rolling bearing 7 comprises a cage 8 with pockets 31 in which two rolling elements 1 arranged side by side are respectively arranged. In this case, the rolling elements 1 are arranged in such a way that the locking pin 6 can be axially displaced against the forc...

Abstract

The invention relates to a linear roller bearing for a linearly movable mounting with non-round roller bodies which the roller body (1) based on a the basic form of a ball has two parallel flattenings(2) running perpendicular to the roller axis.

Description

technical field [0001] The invention relates to a linear rolling bearing with non-circular rolling bodies for linearly movable mounting and to a gear shifting device with a linear rolling bearing. Background technique [0002] For specific applications, rolling bearings with non-circular rolling elements have been proposed. From FR 1 031 490 A is known a linear rolling bearing whose rolling elements have a cylindrical basic shape, wherein the middle section of the rolling elements is concavely arched for fitting into the bearing inner ring, and the two outer rolling elements The body section is conically shaped for matching the bearing outer ring. However, the production of such multi-segment rolling bodies is complex and expensive. [0003] In DE 40 41 489 A1 a rolling element has been proposed with non-circular rolling elements which, in cross-section, can have similarly triangular or triangular prism shapes. In this way, bearing friction in rolling bearings should be r...
