Support bearing, in particular running roller

Abstract

The invention relates to a support bearing, for example for straighteners, having an outer ring (2, 24, 41), having an inner ring (7, 23, 31, 40) and rolling bodies (1) which can roll between the outer ring (2, 24, 41) and the inner ring (7, 23, 31, 40) on raceways, wherein a bending moment prevails between the rings (2, 24, 41, 7, 23, 31, 40) as a result of a load with a fixed direction of action. With the aim of compensating for the bending moment, it is proposed to provide an outer raceway of the inner ring (7, 23, 31) and / or an inner raceway of the outer ring with a profiling with a variable diameter in the axial width, wherein the profiling is adapted or approximated to a non-cylindrical bending line caused by the bending moment in the rolling contact, and the bending line is defined by a line, on which bending forces which are transmitted from the inner ring (7, 23, 3) to the rolling bodies (1) and are caused by the bending moment lie substantially perpendicularly. As a result, in particular, the disadvantageous edge loading in a given load direction is suppressed, with the result that more rolling bodies (1) can transmit load between the rings (2, 24, 41, 7, 23, 31, 40) at the same time.

Description

technical field [0001] The invention relates to a supporting bearing, for example for a straightening machine, with an outer ring, an inner ring and between the outer ring and the inner ring rolling bodies that can roll on raceways, wherein, by having a fixing effect directional load while there is a bending moment between the loops. Background technique [0002] In support bearings (also referred to as load bearing bearings), the axial orientation of the shaft is assumed by one or more bearings, depending on the direction of the introduced forces. Guide rollers (in particular backup rollers, cam rollers or ball bearing guide rollers) belong to the support bearing. Support rollers are fully assembled needle or roller bearings with particularly thick-walled outer rings, which are also used in multi-roll rolling stands, straightening machines, cam drives, guide rails, transport facilities and linear guides system (eg DE102010036248A1). [0003] Cam rollers are support rolle...

AI Technical Summary

Problems solved by technology

[0005] Furthermore, it is problematic that precisely the area of ​​the rolling contact can be particularly damaged due to edge loads in the event of a bending moment, and the service life of the support bearing is likewise significantly impaired

In addition, there can be large uneven loads between the outer rolling bearing row and the inner rolling bearing row
