Problems solved by technology

[0005] Furthermore, the condition of the seals is very difficult to assess and judge due to often very poor access
Since such rotor bearings, which often weigh several tons, are also connected to the generator and, if necessary, to other components of the connection structure, it is not always possible, for example, to keep dirt out of the area of ​​the seals during installation work, maintenance work or repair work. In addition, these dirt can damage the sealing lip and thus adversely affect the overall sealing effect

Embodiment Construction

[0035] A preferred application of the sealing principle according to the invention is depicted by way of example in the drawing. It is a rolling bearing 1 which is preferably intended to be used in a wind power plant, in particular as a rotor bearing or main bearing.

[0036] Two concentric bearing rings can be seen, namely an inner ring 2 having a planar circular configuration and an outer ring 3 with a corresponding geometry surrounding the inner ring on the outside. Preferably, the two rings 2 , 3 each have a flat end face 4 , 5 which can serve as a connection face for connection to a base or to a fitting or machine part. For this purpose, at least one end face 4 , 5 of each bearing ring 2 , 3 is provided with a plurality of fastening means arranged in the form of a rim, in particular for the insertion or screwing of mechanical bolts, (threaded) pins or similar The fastening hole 6 of the object, the longitudinal axis of which preferably passes through the relevant end fac...

Abstract

The invention relates to a sealing assembly for a rolling bearing, comprising two rings which are concentric to one another and are spaced apart from one another by a peripheral gap in which one or more rows of revolving rolling elements are disposed, such that the two rings can be rotated with respect to one another about the common axis thereof, and wherein the gap in the region of at least one of the two mouths thereof is sealed, wherein in the region of a gap seal at least two sealing rings are provided, each having at least one sealing lip and an anchoring region on a surface region of the relevant sealing ring which faces away from the sealing lip, wherein the sealing rings are fixed to the same rolling bearing ring, while the respective sealing lips thereof rest against the other rolling bearing, namely against surface regions having the same or similar cross-sections.

Description

technical field [0001] The invention relates to a sealing system for a rotary connection, in particular for a rolling bearing having two rings concentric with each other, which are spaced apart from each other by a gap surrounding the circumference, in which gap one or more rows are arranged Circumferential rolling bodies, so that the two rings can rotate about their common axis relative to each other, and wherein the gap is sealed in the region of at least one of its two openings. Background technique [0002] The range of application of rotary connection devices is generally very wide, especially the range of application of rolling bearings is particularly wide. Rotary connections according to the class, in particular rolling bearings, are very frequently lubricated with grease and rarely with oil. The lubricating medium is trapped in the area of ​​the (rolling) bearing by preferably seals on both sides. Often individual shaft sealing rings are used as seals, which are f...
