Problems solved by technology

Furthermore, it is disadvantageous that the sacrificial anodes that are consumed during the operation of the rolling bearing can only be replaced with great effort
Also disadvantageous is that the grooves next to the raceways weaken the bearing ring as a whole

Embodiment Construction

[0020] figure 1 Shown is a bearing designed as a rolling bearing, which comprises a first bearing ring 1 designed as an outer ring and a second bearing ring 2 designed as an inner ring, wherein each of the two bearing rings 1 , 2 is provided with a The rolling elements 5 of the rolling bearing are configured as bearing raceways 3, 4 of rolling raceways.

[0021] The bearing is designed as a medium-lubricated bearing, that is to say, the bearing is passed through by a liquid surrounding medium, which lubricates the bearing raceways 3, 4, the surrounding medium, in particular water, is corrosive, in particular based on chloride ions The surrounding medium can attack the material of the bearing rings 1 , 2 , ie the rolling bearing steel, in a pitting manner, and dissolve it point by point, especially in the vicinity of the bearing raceways 3 , 4 .

[0022] Furthermore, the bearing comprises a sacrificial anode 6 which is assigned to the first bearing ring 1 , ie is electrically ...

Abstract

The invention relates to a bearing lubricated with a medium, particularly a roller bearing or sliding bearing, comprising two bearing rings (1, 2) and a bearing path (3, 4) arranged on each of said bearing rings (1, 2), and a sacrificial anode (6) that is associated with at least one of the two bearing rings (1). The problem addressed by the invention is that of providing a bearing lubricated with a medium and comprising a sacrificial anode, the operational behaviour of said bearing being only slightly influenced by said sacrificial anode. According to the invention, this problem is solved in that the sacrificial anode (6) is arranged outside of the bearing interior (7) which is formed between said bearing rings (1, 2); and in that the sacrificial anode (6) is connected to the bearing interior (7) in an electrically-conductive manner.

Description

technical field [0001] The invention relates to a medium-lubricated bearing according to the preamble of claim 1 . Background technique [0002] In practice, so-called medium-lubricated bearings are known, which are penetrated by a liquid surrounding medium surrounding the bearing and in particular also lubricated. The surrounding medium can especially be an electrolyte, especially water, especially salt water, as long as no specific corrosion-resistant material (but expensive in its application) is provided for the bearing ring, then the salt water will cause damage to the bearing due to its chloride ions. Corrosion of the ring material. Rolling bearing steels in particular in salt water are subject to corrosion, in particular pitting corrosion, during which, especially the bearing raceways of rolling bearings, i.e. the rolling surfaces of the rolling elements of rolling bearings, are The Tao will be damaged in a short time. [0003] In practice, it is known in principle...
