Embodiment Construction

[0027] figure 1 A bearing 1 is shown comprising a fixed inner ring 2 and a rotating outer ring 4 which define between them a bearing interior 6 in which rolling elements (not shown) may be arranged. As an alternative not shown, the outer ring 4 can be fixed and the inner ring 2 can be rotated. Therefore, the design of the fixed inner ring 2 also applies to the fixed outer ring 4 .

[0028] A lubricant is usually located in the bearing interior 6 in order to ensure lubrication of the bearing 1 , especially of the rolling elements. The lubricant must be changed during the service life of the bearing 1 . In order to be able to introduce new lubricant into the bearing 1 , the old lubricant must first be removed from the bearing.

[0029] For this purpose, through openings 8 are provided in the inner ring 2 . The through opening 8 is located on the inner ring 2 between the 9 o'clock position and the 3 o'clock position. During the rotation of the outer ring 4 , old lubricant is...

Abstract

A bearing assembly (1) includes an inner ring (2) and an outer ring (4) that define a bearing interior (6) between them and either the inner ring (2) or the outer ring is fixed. When the inner ring is fixed, the inner ring (2) includes at least one substantially radial through opening (8) and when the outer ring is fixed, the outer ring includes at least one substantially axial and / or radial through opening, or at least one substantially axial and / or radial through opening is provided on a ring fixedly connected to the outer ring (4). The through opening (8) is disposed between a 9 o'clock position and a 3 o'clock position on the inner ring when the inner ring is fixed or on the outer ring when the outer ring is fixed.

Description

technical field [0001] The invention relates to a bearing assembly comprising an inner ring and an outer ring forming between them a bearing interior. Background technique [0002] Bearings are usually grease lubricated. Especially in the case of large bearings, such as those used in wind turbines and which may have a service life of 20 years or more, the grease used must be changed continuously. For this, it must be removed from the bearing. For this purpose, an opening is required; however, due to the geometry of the bearing, the opening cannot usually be realized as large as is actually required. If the old grease is not removed from the bearing, the newly replaced grease can escape, or the overflow of grease can occur in an uncontrolled manner through the existing seals. This can lead to damage to the bearing and bearing environment, and can also lead to hazardous operating conditions. In addition, bearings can become overfilled with grease, creating unnecessarily hi...
