Beschreibung
Zusammenfassung:	The invention relates to a bearing assembly (21, 22) for a turbo-engine, comprising a bearing and parts of a bearing temperature detecting device (60), the bearing comprising: a main body (24) having a thermoplastic bearing layer (28) that forms a bearing surface (30), a space (38) is defined in the interior of the main body (24) and of the thermoplastic bearing layer (28) at least for accommodating parts of the bearing temperature detecting device (60), wherein the space (38) comprises a through hole (42) having a first opening (36) located in the bearing surface (30) of the thermoplastic bearing layer (28) and a second opening (40) located in the sec- ond surface (32) of the main body (24), wherein the parts comprise a temperature conducting element (46) having a peripheral surface and a first end (48) with a first end surface, a temperature sensor (64) in contact with the temperature conducting element (46) and a securing fixture (53) that attaches the temperature conducting element. To provide a bearing assembly with improved sealing properties, the first opening (36) of the through hole (42) comprises a chamfer (43) or a step and the first end (48) of temperature conducting element (46) comprises a head which is correspondingly shaped to the chamfer (43) or step in a form fitting manner with the chamfer (43) or step. For reduced downtime in a case of a temperature sensor (64) defect, the center-axis of the temperature sensor extends transversely to the center-axis of the temperature conducting element. L'invention concerne un ensemble palier (21, 22) pour une turbomachine, l'ensemble comprenant un palier et des parties d'un dispositif (60) de détection de la température du palier, le palier comprenant : un corps principal (24) comportant une couche thermoplastique (28) de palier formant une surface (30) de palier ; un espace (38) est défini à l'intérieur du corps principal (24) et de la couche thermoplastique (28) de palier, au moins pour recevoir des parties du dispositif (60) de détection de la température du palier ; l'espace (38) comprend un trou traversant (42) comportant une première ouverture (36) située dans la surface (30) de palier de la couche thermoplastique (28) de palier, et une seconde ouverture (40) située dans la seconde surface (32) du corps principal (24) ; les parties comprennent un élément thermoconducteur (46) comportant une surface périphérique et une première extrémité (48) dotée d'une première surface d'extrémité, un capteur d
