Rolling element guide elements especially for large rolling bearings of the tapered roller type

Abstract

The invention relates to a rolling element guide element for rolling bearings, the rolling element guide element has an inner beam (1), which is arranged between two adjacent rolling elements in the installed state and forms a The first or second beam wall (1a, 1b) facing the corresponding rolling body in the radial direction of the rolling body axis; also having a thrust structure (2) constructed in the region of the corresponding beam wall , to provide at least one roller thrust zone supporting the corresponding rolling body in the direction of revolution; and having a radial guide structure (3) for radially guiding the inner beam. The rolling element guide element according to the invention comprises first and second side edge pieces (4, 5) which protrude beyond the end faces of adjacent rolling elements on the sides of the rolling element guiding element facing away from each other and overlap these end face.

Description

technical field [0001] The invention relates to a rolling element guide, in particular for large rolling bearings of the tapered roller type carrying axial and radial loads, wherein such a rolling element guide is arranged in each case between two successive rolling elements of the rolling bearing In this case, two adjacent rolling elements are supported relative to each other in the circumferential direction, and a minimum distance is ensured between these rolling elements, thereby avoiding direct contact of the rolling elements. Background technique [0002] Hitherto, for large tapered roller bearings (diameter > 2000 mm) in the wind power sector and other fields of application of this bearing size, rolling-element guiding cages were generally used, which can be implemented, for example, as so-called pin-type cage or plastic segmented cage. Plastic segmented cages place a requirement on the bearing design that they must have a multiple of the number of rollers that are...

AI Technical Summary

Problems solved by technology

However, full roller bearings without cages suffer from high friction losses and are overall heavy

Furthermore, there are difficult lubrication conditions in these bearings and thus cause large deviations in predictable life expectancy
