ABSTRACT:
A high-capacity elastomeric combination journal-thrust bearing comprises at least one encapsulated lobe. The encapsulated lobe comprises an outer tubular member having a first ring joined along substantially all of its outer periphery to the inner periphery of the outer tubular member at a first end and having a second ring joined along substantially all of its outer periphery to the inner periphery of the outer tubular member at a second end. The encapsulated lobe further comprises an inner tubular member having the same longitudinal axis of the outer tubular member, and having a third ring joined along substantially all of its inner periphery to the outer periphery of the inner tubular member, spaced between the first and second rings. An elastomer separates and joins the rings to each other and to the tubular members, and the tubular members to each other. As the radial distance from the longitudinal axis increases, the thickness of the elastomer increases.
