Abstract

Disclosed is a method which increases the speed threshold where air ingestion occurs by placing the oil-to-air interface at the ungrooved section of an oil bearing. Thus, the duration of oil bearing continuous run life is improved.

Oil Bearing with Air to Oil Interface at Ungrooved Section

      Disclosed is a method which increases the speed threshold where
air ingestion occurs by placing the oil-to-air interface at the
ungrooved section of an oil bearing.  Thus, the duration of oil
bearing continuous run life is improved.

      Adding recirculation path 11, 12, 13, and 14 in a traditional
oil bearing as illustrated in Fig. 1 can ensure that the oil to air
interface will not be located over the grooves.  A second approach is
illustrated in Fig. 2, where the oil is pumped into a dead ended cup.
Sufficient oil reservoir is placed at 28 to ensure that the oil to
air interface is located away from the grooved region.
