Rolling bearing device and rolling bearing

Abstract

The present invention discloses a rolling bearing device having at least two rolling bearings, at least one surrounding retention body is arranged between the rolling bearings, and each retention bodyis fixed in position between the bearing rings through radial sections. The invention also discloses the rolling bearings with surrounding retention bodies as an axial confinement structure for a lubricant space. Each retention body is, for example, an I-shaped or flat or L-shaped profile.

Description

technical field [0001] The invention relates to a rolling bearing arrangement having at least two rolling bearings, the bearing rows of which are each arranged in a lubricant space, the bearing rows being delimited radially by two bearing rings each and The mutually facing axial ends of the bearing rows are each delimited by a sealing element and at the mutually facing axial ends of the bearing rows are delimited by at least one retaining body for retaining lubricant. The invention also relates to a rolling bearing for such a rolling bearing arrangement. Background technique [0002] Radial and axial rolling bearings are used to rotatably support two bodies relative to one another. The rolling bearing has at least two bearing rings which can each be arranged on the object to be supported and which can rotate about a common axis. In order to achieve a mutual movement of the bearing rings that is as frictionless as possible, rolling bodies are arranged between the bearing ri...

AI Technical Summary

Problems solved by technology

For multi-row rolling bearings, horizontal transport often presents the problem that the bearing grease passes from one bearing row to the other due to the influence of gravity and / or temperature and / or vibrations

This grease migration can lead especially during the start-up phase of rolling bearings to problems such as increased friction, temperature peaks, increased bearing internal pressure and / or grease outflow
