Title
(EN) TRAILING EDGE COOLED BEARING
(FR) PALIER REFROIDI DE BORD DE FUITE
Abstract
(EN)
A trailing edge cooled bearing provides an illustrative embodiment of an apparatus for increasing heat transfer in various bearings, including but not limited to radial and axial tilting pad bearings. In the illustrative embodiment, the trailing edge cooled bearing may comprise at least one journal pad having a leading and trailing edge. The trailing edge may include a trailing edge face having one or more grooves formed therein. A spray bar may having one or more apertures formed therein may be positioned adjacent the trailing edge face to deliver fluid thereto.
(FR)
L'invention concerne un palier refroidi de bord de fuite procurant un mode de réalisation donné à titre d'illustration d'un appareil permettant d'augmenter le transfert de chaleur dans différents paliers, y compris mais de façon non limitative des paliers à patins oscillants. Dans le mode de réalisation donné à titre d'illustration, le palier refroidi de bord de fuite peut comporter un patin tourillonné ayant un bord d'attaque et un bord de fuite. Le bord de fuite peut comprendre une face de bord de fuite ayant une ou plusieurs rainures formées dans celui-ci. Une rampe de pulvérisation peut avoir une ou plusieurs ouvertures formées dans celle-ci et peut être positionnée de manière adjacente par rapport à la face de bord de fuite pour acheminer le fluide sur celle-ci.
