The main application relates to a roller bearing guide but a straight guide with a 3 guide cable in one plane and guide rails arranged in parallel with between Guide rails and guide slides arranged and endless circumferentially guided rolling bodies.

The subject matter of the main application is characterized in that the rolling elements consist of balls or barrel-shaped rollers beetenon and the roller tracks of the rolling elements between guide rails and guide carriage essentially the Vtälzbereioh the rolling elements are adapted and have a large Umsohlingungswinkel for the rolling area of the rolling elements.

The subject of the main application is a rolling bearing guide τοπ high load capacity, which is also self-provided . The advantages only appear when the guide carriages are mounted.

In a further development of the subject matter of the main application, the present invention therefore set itself the task of creating a roller bearing guide in which lifting of the guide base is avoided. This object is achieved according to the invention solved by the fact that the associated collars of the Rolling elements in the guide rail and guide carriage than in the Yersühisbeebsns opposite one another roughly V-shaped designed grooves with provided in the flanks and for the Viälzbereich of the rolling elements a large looping angle forming roundings are formed and arranged on the guide carriage at the ends of the Umlenketüoke, the rolling elements not touching "wire" are provided in the installed state.

In the arrangement according to the invention, the rolling elements are therefore located both in the runways of the guide as well as you in the runways of the guide rails at two points each, with a total of four contact points in an area of 35 ° to 50 °, expediently at 45 °, eu of the shift plane Hegen · This ensures that the guide carriage does not move while maintaining the self-prestressing of the door part

can take off.

The safety wire is dee at the ends of the deflection piece Guide carriage attached so that it is under constant

Pührungssohlittens no contact with the rolling elements occurs. For this purpose, it is further provided in an expedient embodiment of the arrangement according to the invention that at the base of the approximately V-shaped grooves are provided in the guide rails to accommodate the Sloherungsdrraht.

In the drawing, an exemplary embodiment of the invention is shown. The figure shows the left part of a roller bearing guide ia cross section *

In the exemplary embodiment shown, there are two parallel Guide rails are provided, of which the illustrated guide rail is denoted by 2a. On these guide rails is a guide carriage 4a slidable in the direction of the guide rails. For this purpose, channels are provided in the guide carriage 4a, in which rolling elements revolve endlessly are led. The in the shown game of execution as Balls 7 formed rolling bodies run from a Büokfuhrkanal E via a deflection channel 9a between roller tracks 10a and 10b of the guide rail center 4a and runways 11a and 11b of the Guide rails 2a via a further deflection channel (not shown) in the return guide channel 8 back.

702081412.11.70

The roller tracks for the rolling elements in the guide rail 2a and in the guide carriage 4a are approximately V-shaped grooves 20 and 21 respectively. The finish of the grooves 20 or 21 are each rounded so that the runways 10a, 10b, 11a, 11b each have a large Umsole 1 angle for the Rolling range of the rolling elements, in the present case for the The spherical surface of the balls 7 form. The total tier facility * put the Wälakörpera in the approximately V-shaped Grooves 20 and 21 are each at an angle of about 45 ° to the leveling plane.

The groove 21 has a recess 22 at its foot, which serves to hold a safety wire 23 The safety wire 23 is at the ends of the deflection stttoke (not shown) under constant tension so ar ^ ebraoht that Ια built-in State of the guide sole 4a no contact with the fuse wire 23 with the rolling bodies (balls 7) enters.

It is of course also possible to use the return channel 8 under a « to be arranged at an acute angle in relation to the displacement plane
