ABSTRACT:
There is disclosed improved sealing rings having two complementary parts. The sealing rings are used on the shafts of rotating elements. The first ring has an annular face with a recess therein and adapted and constructed to mate with an axially extending flange which extends from the annular face of the second ring. The flange has grooves on the radially outwardly facing surface. The inwardly facing wall of the recess also possesses grooves. Additionally, there is a communicating orifice through the first ring to communicate with the recess. The various grooves are designed to accumulate foreign particles that may be incursive with respect to the journalling means of a driving or driven device. These foreign particles are then expelled through the aforementioned orifice due to centrifugal forces while the device is being employed.
