Abstract
The present disclosure includes features configured to reduce geometric stress concentration of landing gear shock absorber bearing seal grooves. The stress-reducing features are configured to provide a more gradual section area change as stresses approach a central seal groove axially from either side. The auxiliary stress-reduction grooves can have outwardly sloped surfaces for gradual section area change that increase in diameter approaching the central seal groove. As a result, the geometric stress concentration of the central seal groove can be significantly reduced within the corner radii of the rectangular groove by redirecting stress flow lines around the central seal groove, such as in axial loading and pressure loading from the central chamber during use of the shock-absorbing strut.
