TURBOMACHINE BEARING HOUSING |
摘要 |
The invention concerns a turbomachine bearing housing (E) comprising a fixed wall (9), a rotating shaft (5), first and second seals (10, 20) between the wall and the shaft, and a chamber (Cam) between the fixed wall (9) and a stator element (19) supplied with air via an opening (19a) close to said shaft (5). The housing is characterised by the fact that an air guide means (30) is arranged along the surface of the wall (9) of the housing, outside same, such that at least a portion of the air exiting the guide means passes between the first seal (10) and the shaft, said guide means being supplied with air by an air intake separated radially from the shaft, the air from the air intake being at a higher pressure than at the shaft. |
