The flange width being less than or equal to approximately 2.1 millimeters.
Claims11
A method of configuring a bearing compartment for use in a rotational assembly, the bearing compartment having a bearing housing, the method comprising:
- disposing in the bearing housing a seal assembly, the seal assembly having an annular seal housing that comprises a plurality of circumferentially disposed orifices having a first diameter,
- providing a plurality of coil springs, each of the plurality of coil springs having a second diameter, a first axial end and a second axial end,
- providing a plurality of spring guides, wherein each of the plurality of spring guides comprises a first body portion having a third diameter that is smaller than the first diameter, a second body portion having a fourth diameter that is smaller than the second diameter, a flange portion that includes a flange width and a flange diameter, the flange diameter being larger than the second diameter, the flange portion extending circumferentially between the first body portion and the second body portion, the flange portion having a first axial surface and an opposing second axial surface,
- positioning the plurality of spring guides in the respective plurality of orifices wherein each first body portion is received within a respective one of the plurality of orifices and each first axial surface is disposed against the annular seal housing,
- disposing the first axial end of each of the plurality of coil springs against the bearing housing, and
- disposing the second axial end of each of the plurality of coil springs against a second axial end of a respective one of the plurality of spring guides so that the second body portion of the respective one of the plurality of spring guides extends therein.
