| 摘要 |
The invention relates to a machine comprising: a shaft (2) having a stage (3) such that a first shaft section (9) having a first diameter (11), a second shaft section (10) having a second diameter (12) that is shorter than the first diameter (11), and a radially extending and rotatable shaft end surface (6) are formed; a housing (5); and a bearing (4) which supports the shaft (2) on the housing (5) by its second shaft section (10), and which is lubricated by a lubrication fluid, wherein the shaft end surface (6) is facing a radially extending and stationary bearing end side (7), whereby a sealing chamber (13) is formed that can be applied with a sealing fluid, by means of which sealing fluid the lubrication fluid can be prevented from leaving the bearing (4), and which sealing chamber is axially limited by the shaft end surface (6) and the bearing end side (7), and radially inwardly limited by the second shaft section (10) released from the bearing (4), characterised in that a radially extending and stationary separator plate (15) is introduced into the sealing chamber (13), such that an aerodynamic shielding of the bearing end side (7) from the shaft end surface (6) is achieved, whereby, when the shaft (2) is rotating, the region between the separator plate (15) and the bearing end side (7) is substantially non-rotational. |
