Abstract:
1. A rotary bearing, comprising a radially inner bearing part and a radially outer bearing part rotatable relative to one another about an axis; a lubricant passage arrangement for supplying a lubricant both to engaging surfaces of said radially inner bearing part and said radially outer bearing part and also to a further lubricating point, said lubricant passage arrangement including at least one first lubricant passage having one end which opens in an inner peripheral surface of said radially outer bearing part and another end which is connectable with a lubricant supply, at least one second lubricant passage which leads from an outer peripheral surface of said radially inner bearing part to an inner peripheral surface of said radially inner bearing part, and a ring chamber between said inner peripheral surface of said outer bearing part and said outer peripheral surface of said inner bearing part, said at least one first lubricant passage and said at least one second lubricant passage opening in said ring chamber; a lubricant distributing element formed as a separate part which is arranged in said ring chamber, said lubricant distributing element being in a lubricant supplying connection with said at least one first lubricant passage; means forming at least one first outflow path associated with said lubricant distributing element for supplying lubricant to the engaging surfaces of said bearing parts, and means for providing at least one second outflow path associated with said lubricant distributing element for supplying lubricant through said at least one second lubricant passage to said at least one further lubricating point, wherein said first outflow path is formed between an outer surface of said lubricant distributing element which extends substantially orthogonal to an axial direction and a counter surface of said ring chamber whit extends also substantially orthogonal to the axial direction.
