Abstract
A rolling bearing-cooling device for a bearing arrangement is provided. The bearing arrangement includes at least one rolling bearing for mounting a drum of a decanter centrifuge or solid bowl centrifuge. The rolling bearing-cooling device includes a lubricant supply line, a lubricant discharge line, a cooling air supply line, and a cooling air discharge line. The lubricant supply line is spaced from the cooling air supply line and is opposite the cooling air discharge line, and the cooling air supply line is opposite the lubricant discharge line with regard to the rolling bearing.
Claims9
A bearing arrangement, comprising:
- a housing, comprising
- a rolling bearing arranged to bear a bowl of a centrifuge;
- and
- a rolling bearing cooling apparatus, comprising
- a lubricant source;
- a lubricant supply line coupled to the lubricant source;
- a lubricant discharge line;
- a cooling air source;
- a cooling air supply line coupled to the cooling air source;
- and
- a cooling air discharge line,
- wherein an inlet opening of the lubricant discharge line lies on a larger radius of the housing than that of an inlet opening of the cooling air discharge line, and
- wherein the lubricant and cooling air discharge lines are proximate to the rolling bearing, the lubricant discharge line is arranged on a first lateral side of the rolling bearing relative to the cooling air discharge line, and the cooling air discharge line is arranged on a second lateral side, which is opposite of the first lateral side, of the rolling bearing relative to the lubricant discharge line, and
- wherein a lubricant flow supplied to the rolling bearing through the lubricant supply line and a cooling air flow supplied to the rolling bearing through the cooling air supply line are each guided through axial openings in the rolling bearing, between an inner ring of the rolling bearing and an outer ring of the rolling bearing.
A centrifuge, comprising:
- a bowl;
- and
- a housing, comprising
- a rolling bearing arranged to bear the bowl of the centrifuge;
- and
- a rolling bearing cooling apparatus, comprising
- a lubricant source;
- a lubricant supply line coupled to the lubricant source;
- a lubricant discharge line;
- a cooling air source;
- a cooling air supply line coupled to the cooling air source;
- and
- a cooling air discharge line,
- wherein an inlet opening of the lubricant discharge line lies on a larger radius of the housing than that of an inlet opening of the cooling air discharge line, and
- wherein the lubricant and cooling air discharge lines are proximate to the rolling bearing, the lubricant discharge line is arranged on a first lateral side of the rolling bearing relative to the cooling air discharge line, and the cooling air discharge line is arranged on a second lateral side, which is opposite of the first lateral side, of the rolling bearing relative to the lubricant discharge line, and
- wherein a lubricant flow supplied to the rolling bearing through the lubricant supply line and a cooling air flow supplied to the rolling bearing through the cooling air supply line are each guided through axial openings in the rolling bearing, between an inner ring of the rolling bearing and an outer ring of the rolling bearing.
