SEAL ASSEMBLY AND/OR COMPONENT THEREOF AND METHOD OF MANUFACTURING AND/OR USING SAME

摘要

A sleeve, rotary seal, rotary seal assembly, shaft with an integrated primary surface, rotary seal assembly component, and/or any combination thereof which preferably results in rotary seals having a higher tolerance for radial eccentricity (static eccentricity and/or dynamic eccentricity). Related methods of manufacturing, using, and/or providing same are also set forth.

1. A seal assembly configured to dynamically seal a rotary shaft having a central shaft axis, the seal assembly comprising:
a sleeve configured for positioning over the rotary shaft, the sleeve having a radially inner surface configured to contact the rotary shaft and a radially outer surface, the radially outer surface including a primary surface oriented at an angle relative to the central shaft axis when the sleeve is positioned over the rotary shaft; and a seal having a first seal end and a second seal end, the first seal end being configured for securing to a gland disposed about the rotary shaft such that, when viewed in axial cross section, the seal approaches an orientation perpendicular to the central shaft axis proximate to the first seal end, the second seal end being configured to create a dynamic seal with the primary surface of the sleeve wherein the angle of the primary surface reduces an amount of deflection of the seal resulting from radial eccentricity of the rotary shaft.
