초록 ▼

The present invention is a hydrodynamically lubricated interference type rotary shaft seal suitable for environmental exclusion and high pressure lubricant retention which incorporates an environment-side groove to control and minimize interfacial contact pressure at the dynamic sealing interface, which permits optimum hydrodynamic film thickness, thereby significantly lowering the self-generated heat produced by the seal, as compared to the prior art. The cool-running nature of the present invention permits the use of higher modulus seal materials and higher surface speeds, compared to the prior art, and allows the seal to operate in applications with relatively poor heat dissipation. The controlled interfacial contact pressure of the present invention also permits effective hydrodynamic lubrication with lower viscosity lubricants, including water.

대표청구항 ▼

A resilient hydrodynamic seal for location within a housing defining a lubricant chamber containing lubricant and for dynamic interference sealing engagement with a relatively rotatable surface and for serving as a partition between the lubricant chamber and a contaminated environment, comprising: (a) a circular ring-like seal body being composed of resilient sealing material and defining axial ends, one of said axial ends being a lubricant end adapted to be exposed to the lubricant chamber, the other of said axial ends being an environment end adapted to be exposed to the contaminated environment; (b) a circular dynamic sealing lip being defined by said circular ring-like seal body at said environment end and having an axially varying edge at one axial extremity thereof defining a hydrodynamic end for exposure to lubricant in the lubricant chamber and having an abrupt axially nonvarying edge at the opposite axial extremity thereof and defining an environment end of said circular dynamic sealing lip for exposure to the contaminated environment, said circular dynamic sealing lip further having a peripheral sealing surface for establishing a seal contact footprint of varying axial width with the relatively rotatable surface; and (c) said circular ring-like seal body defining radially spaced flexible generally circular body rims at said environment end of said circular ring-like seal body and defining a generally circular groove intermediate said generally circular flexible body rims, said generally circular groove opening toward the contaminated environment, said radially spaced flexible generally circular body rims being radially flexible inwardly to control interfacial contact pressure of said seal with the housing and with the relatively rotatable surface and thus regulating hydrodynamic film thickness, one of said generally circular body rims defining at least a portion of said circular dynamic sealing lip.
