Brush seal for a bearing cavity

摘要

A rotatable shaft is mounted in an oil bearing and generates oil mist. One or more brush seals are carried by the bearing housing for substantially sealing the oil mist in the bearing cavity from migration outwardly. The bristles have a diameter in the range of 0.5 to 1.0 mils, preferably about 0.56 mils. The bristles have a stiffness less than 1 psi/mil and preferably about 0.2 psi/mil. The brush seal is mounted on a sheet metal mounting plate, enabling an inexpensive securement of brush seals to the housing.
