Abstract
An assembly is provided that includes a shaft, a bearing, a stator seal element, a rotor seal element and a shield. The shaft extends along an axis. The bearing supports the shaft and receives lubrication fluid. The stator seal element circumscribes the shaft. The rotor seal element is mounted on the shaft axially between the bearing and the stator seal element. The rotor seal element forms a seal with the stator seal element. The shield substantially prevents the lubrication fluid from traveling axially away from the bearing onto the rotor seal element.
Claims19
A turbine engine assembly, comprising:
- a turbine engine shaft extending along an axis;
- a bearing including an inner race and an outer race, the inner race mounted on the shaft and separated from the outer race by a gap;
- a rotor seal element mounted on the shaft;
- a shield blocking all axial lines of sight between the gap and the rotor seal element;
- and
- an annular stator seal element configured to engage and form a seal with the rotor seal element.
An assembly, comprising:
- a shaft extending along an axis;
- a bearing supporting the shaft, the bearing configured to receive lubrication fluid;
- a stator seal element circumscribing the shaft;
- a rotor seal element mounted on the shaft axially between the bearing and the stator seal element, the rotor seal element configured to engage and form a seal with the stator seal element;
- and
- a shield comprising an annular disk configured to prevent the lubrication fluid from traveling axially away from the bearing onto the rotor seal element;
- the annular disk extending axially between opposing disk side surfaces, and the annular disk extending radially to a disk end surface, wherein the disk end surface extends axially between and is contiguous with the opposing disk side surfaces.
