Abstract
A compression linkage is disclosed for use between a first swivel pin having a first thermal expansion characteristic and a second swivel pin of a second and differing thermal expansion characteristic, comprising: (a) a first shaft comprised of substantially the same material as the first pin and having a mateable end and another end adapted for swivel connection to said first pin; (b) a second shaft comprised of substantially the same material as the second pin and having a mateable end and another end adapted for swivel connection to said second pin; and (c) means providing a rigid compression joint between the mateable ends of said first and second shafts. Preferably, the first pin is adapted to operate in a high temperature environment, such as 400.degree.-500.degree. F., and is comprised of a ceramic effective to have a flexural strength of at least 100,000 psi (500 MPa) in such temperature range. The material for the second pin is preferably comprised of metal having a tensile strength of at least 550 MPa and a coefficient of thermal expansion in the range of 8-20 ppm/.degree. K. The metal may be selected from the group consisting of high carbon steel and sintered powdered metal.
