RADIAL SHAFT SEAL WITH STATIC AND HYDRODYNAMIC SEALING FEATURES |
摘要 |
<p>A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air-side of the shaft seal from an oil-side of the shaft seal is provided. The seal includes an annular mounting portion; an elastomeric seal body connected to the mounting portion, and a seal lip connected to the seal body. The seal lip has an annular inner sealing surface extending axially between an oil-side end and a free air-side end. The inner sealing surface has a first groove region and a circumferentially continuous annular static band. The first groove region is spaced axially from the static band and extends between the static band and the oil-side end to pump lubrication toward the oil-side of the seal. The static band prevents the lubrication from leaking from the oil-side to the air-side of the seal.</p> |
