SEAL ASSEMBLIES AND RELATED METHODS

摘要

Spring energized seal assemblies configured for use in static or dynamic application and methods of using and making same are provided. The seal assemblies can each have a sealing component and optionally a backup ring or a locking ring or both. An annular spring can be used with a spring groove of either the backup ring or the locking to facilitate assembling of the mentioned components of a seal assembly onto each other and the entire seal assembly into a seal cavity of a housing.

主权项

1. A seal assembly suitable for at least one of static, rotary, and reciprocating sealing applications comprising:
a sealing component and a locking ring; wherein the sealing component has a seal lip for sealing a surface of a shaft; wherein the locking ring is engaged to the sealing component and together with the sealing component defining a spring cavity; wherein a first annular spring is positioned within said spring cavity to energize the seal lip of the sealing component; wherein the locking ring comprises at least one spring groove; wherein a second annular spring is positioned within the at least one spring groove; and wherein the second annular spring is configured to bias against a housing.
