Coupling between at least two members to be subjected to high thermal stress

摘要

A coupling is provided wherein each of two members to be coupled are provided with a series of centering elements for preventing decentering of the two members during periods of thermal change. Inner and outer centering elements are provided on each member, each element having centering surfaces extending radially and transversely relative to contact surfaces of the members to be coupled. The centering elements of one member contact the centering elements of the other member only at their centering surfaces, thereby allowing for thermal expansion toward other surfaces of the elements without deformation of adjacent elements. Additional decentering arrangements are disclosed for coupling flat members. The couplings disclosed are particularly advantageous for coupling metal to ceramic.
