Embodiment Construction

[0036] exist Figures 1a-1d In , various parts of the exemplary embodiment of the sealing assembly 100 of the present invention are respectively shown in cross-section. The seal assembly 100 is used to seal a (not shown) bearing of a shaft 10 disposed in a partially shown bearing housing 12 . Figure 1a , 1c and 1d show cross-sections along the intended axis of rotation R of the shaft 10, which is horizontal in the installed position (wherein the respective sections have different inclinations with respect to the horizontal plane); in Figure 1b , a cross section perpendicular to this axis R is shown.

[0037] The seal assembly 100 comprises a seal housing 110 and in the present case two likewise shaped seal rings 121 and 122 held by the seal housing, each of which bears against the shaft protection sleeve 11 of the shaft 10 and Both therefore have the same sliding diameter D. An annular chamber 130 is formed between the sealing rings 121 and 122 , which is delimited by the...

Abstract

A seal assembly (100) for sealing a shaft bearing (14) includes a seal housing (110), and first and second seal rings (121, 122) retained by the seal housing. The first and second seal rings (121, 122) are configured to around the axis so as to form an annular chamber (130) between the first and second seal rings. The annular chamber (130) is connected to an oil space (13) through a connecting channel (111). In a mounting position of the seal assembly, the connecting channel is configured to permit a fill-level equalization between the oil space and the annular chamber when the oil space is filled to a first possible fill level (N1) and to prevent the fill-level equalization between oil space and annular chamber when the oil space is filled to a second possible fill level (N2). In addition, the seal housing (110) used for the seal assembly is disclosed.

Description

technical field [0001] The present invention relates to a sealing assembly for sealing bearings, such as thrust bearings or radial bearings, in particular azimuth thrusters of ships. Background technique [0002] Bearings are usually set in special housings that include an oil space filled with oil up to a specified fill level to lubricate the bearings. For sealing, a sealing ring is usually used which abuts against the periphery of the shaft or against a shaft protection sleeve surrounding the shaft. Here, the sealing ring is usually held in a sealing housing which is offset in the axial direction relative to the bearing housing; in this document "axial" as well as "radial", "rotational direction" and The specification of the term from which it is derived always refers - unless stated otherwise - to the (intended) rotating shaft of the shaft to be sealed. [0003] Abrasion, material fatigue, unforeseen loads, etc. can cause damage to the seal ring, limiting its function o...
