Abstract
Abstract The invention relates to a system for the continuous lubrication of a rolling bearing. The rolling bearing is arranged in a bearing bore provided at a bearing bracket. The lubrication system comprises a reservoir containing a supply of lubricating oil, from which at least one wick leads to the bearing, the lubricating oil being suppliable to the bearing by the wick. To obtain as long as possible a continued lubrication period with as small as possible a supply of lubricating oil, one or more oilproof cavities are provided as lubricating oil reservoir in a separate bearing cover attachable to the bearing bracket. Such a bearing cover can be postfitted in machines to increase the period of continued lubrication.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
136 words
In a system for the continuous lubrication of a rolling bearing arranged in a bearing bore provided at a bearing bracket, which comprises a reservoir containing a supply of lubricating oil and at least one wick leading from this reservoir containing a supply of lubricating oil being suppliable to the bearing through said wick, the improvement wherein: at least one oilproof cavity filled with oil is formed in a separate bearing cover attachable on the bearing bracket and covering the bearing bore; a felt ring is located between the bearing cover and the rolling bearing, contacting the rolling bearing and communicating with the wick; and said bearing cover further comprises two interconnectable cover halves having depressions extending in axial and circumferential directions, said depressions being opposite each other after the two halves have been fitted together.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
85 words
The system according to claim 1, wherein on the two cover halves wall portions are provided, extending from the radially external depressions radially inward and forming a contact area for the two halves, a channel being formed between said wall portions by corresponding, radially extending embossments, the wick being placed into said channel and passed through a bore provided at the radially inner end of the channel to the felt ring disposed at the wall portion of the cover half turned toward the rolling bearing.
