Abstract
A rolling-element bearing assembly includes a device for supplying a fluid into a rolling chamber of a rolling-element bearing. The device includes a fluid supply ring disposed in the axial direction lateral to the rolling-element bearing, and at least one fluid conduit for conveying the fluid from the fluid supply ring into the rolling chamber. One end of the conduit protrudes into the rolling chamber so as to be disposed axially between a rotation-induced air cushion and the rolling elements and/or a raceway surface of the rolling element bearing.
Claims16
A rolling-element bearing assembly comprising:
- at least one rolling element bearing having at least one inner ring, at least one outer ring, a rolling chamber defined between the inner and outer rings and a plurality of rolling elements disposed within the rolling chamber, the rolling elements generating a rotation-induced air cushion in the rolling chamber axially adjacent to the rolling elements during operation,
- a fluid supply ring disposed lateral to the rolling-element bearing and on an opposite side of the rotation-induced air cushion, and
- at least one fluid conduit configured to convey a fluid from the fluid supply ring through the air cushion into the rolling chamber, wherein a discharge end of the conduit protrudes into the rolling chamber and is disposed close enough to the rolling elements and/or to at least one raceway surface, such that the discharge end of the conduit is disposed axially between the rotation-induced air cushion and the rolling elements and/or the at least one raceway surface.
