Abstract: 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.

Abstract: A heat exchanger having a tube bundle disposed within a housing with a resilient end structure disposed in compressed, plug-forming relation at least partially across the heat exchanging cavity. The resilient end structure includes one or more boundary segments extending between an internal wall of the housing and the perimeter of the tube bundle. The boundary segment includes a combination of materials having differing compression characteristics providing enhanced support to the boundary segments.

Abstract: An elastomeric bushing can be incorporated into a pin joint assembly of a machine. The elastomeric bushing can be configured to allow at least three degrees of relative rotational movement, including roll, pitch, and yaw. The elastomeric bushing can rotate with respect to a pin about a longitudinal axis thereof. The elastomeric bushing is adapted to accommodate out-of-plane movement. The elastomeric bushing can include a plurality of alternating elastomeric layers and metal plies.

Abstract: A work machine tire includes an annular body of elastomeric material that includes a middle radial region. A plurality of unpressurized cavities are defined by the middle radial region and are distributed in a pattern that includes a first radial band of cavities and a second radial band of cavities. Each cavity of the first radial band of cavities is oriented at a positive angle with respect to a radius therethrough, and each cavity of the second radial band of cavities is oriented at a negative angle with respect to a radius therethrough. A material volume of the middle radial region is more than one and a half times greater than the combined void volume of the plurality of cavities.
