Problems solved by technology

With these linear ball bearings, the problem arises that the rolling bearing elements which run around in the running channel have to traverse the separating points (Trennstelle) between the individual components of the housing several times, which leads to relatively high wear.

Embodiment Construction

[0035] exist figure 1 and 2 The linear guide 1 shown in FIG. 1 comprises a carrier body 2 at which, forming a guide structure 4 with a longitudinal axis 3 , two linear guide rails 5 are arranged such that they are oriented parallel to the longitudinal axis 3 . Displaceably positioned on the guide structure 4 according to the double arrow 6 in the axial direction of the longitudinal axis 3 is a guide slide 7 which overlaps the guide structure 4 in a cursor-like manner and is displaceable by means of a linear guide unit 8 ground support at each rail 5.

[0036] The two linear guide units 8 are preferably configured identically. one of the Figures 3 to 8 shown separately. The figures also show at least one fastening interface 12 formed on the linear guide unit 8 , with which the linear guide unit 8 is fastened on the guide slide 7 in a preferably detachable manner. The at least one fixing interface 12 is preferably formed by one or more fixing holes through which the linear...

Abstract

The present invention relates to a linear guide device having at least one linear guide unit (8), the linear guide unit (8) having a housing (15), the housing (15) configured with two surround channels (16, 17), the bearing element (32) located therein. A housing (15) and configured to contain more than two-piece cover plate (36, 37), arranged in between the core body (34) and surrounding the core (34) of the frame body (35). In addition to the support - no collaboration core (34) of the channel cross section (66) outside the area, the surround channel (16, 17) is formed by a frame structure (35) of the guide groove (75), the corresponding is the cover (36, 37) in a cover.

Description

technical field [0001] The invention relates to a linear guide (Linearführungseinrichtung) with at least one linear guide unit having a housing with two cover plates spaced apart from each other in the height direction and a separate a core body (Kernkörper) and a separate frame body surrounding the core body in a frame plane perpendicular to the height direction, wherein the housing defines two surrounding passages spaced apart from each other in the height direction and closed annularly themselves, It respectively accommodates a large number of rolling bearing elements arranged one behind the other in the longitudinal direction of the channel, which can carry out an orbiting movement in the longitudinal direction of the channel, wherein each orbiting channel has a frame leg associated with the front of the frame body. rectilinear support-channel section that supports the rolling bearing element located therein against external forces, associated with the rear frame leg (42b)...
