Boot Seal For Machine System And Method

摘要

A machine system includes a first component, a second component, and a joint assembly pivotably connecting the first and second components in a finite angular pivoting range. A boot seal seals between the first and second components, and has a rest configuration where the boot seal has a curvilinear taper, and is deformable to a squished configuration forming a radially outward bulge. The radially outward bulge stores an energy of compression of the boot seal, to bias a sealing ring in the boot seal against the second component.

1. A machine system comprising:
a first machine component; a second machine component pivotable relative to the first machine component in a finite angular pivoting range; and a joint assembly connecting the first and second machine components and including a boot seal sealing therebetween; the boot seal defining a center axis extending between a first and a second axial end, and having a first and a second sealing ring positioned at the first and second axial ends, respectively, the first sealing ring being in radial contact with the first machine component, and the second sealing ring being in axial contact with the second machine component; and the boot seal being held in axial compression between the first and second machine components, and including a radially outward bulge storing an energy of the axial compression such that the second sealing ring is biased against the second machine component.
