Mitigating vortex pumping effect upstream of oil seal |
摘要 |
Oil sump seal pressurization apparatus for a turbine engine are disclosed. An example oil sump seal pressurization apparatus may include an oil sump comprising at least one bearing mounted therein; an oil seal operatively disposed between a non-rotating structural member of the sump and the shaft; a generally radially inwardly oriented passage arranged to supply pressurization air to the outward side of the oil seal; a generally radially outwardly oriented pathway arranged to receive at least some of the pressurization air from the passage, the pathway being at least partially defined by a generally radially outwardly extending arm disposed on the shaft, the arm rotating with the shaft; and/or a windage shield at least partially separating the passage and the pathway, the windage shield being operatively mounted to the non-rotating structural member of the sump. |

1. An oil sump seal pressurization apparatus for a turbine engine, the oil sump seal pressurization apparatus comprising:
an oil sump comprising at least one bearing mounted therein, the bearing allowing rotation of a shaft with respect to the sump; an oil seal operatively disposed between a non-rotating structural member of the sump and the shaft, the oil sealing having an inward side exposed to an interior of the oil sump and an outward side; a generally radially inwardly oriented passage arranged to supply pressurization air to the outward side of the oil seal; a generally radially outwardly oriented pathway arranged to receive at least some of the pressurization air from the passage, the pathway being at least partially defined by a generally radially outwardly extending arm disposed on the shaft, the arm rotating with the shaft; and a windage shield at least partially separating the passage and the pathway, the windage shield being operatively mounted to the non-rotating structural member of the sump. |
