Abstract
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.
Claims31
A coupling including first and second opposed members clamped to each other by a clamping means, each of said members having a contact surface for contacting one another, each of said members having a series of inner and outer centering elements for centering said members, each of said centering elements having only one centering surface extending outwardly relative to a central region of said member and transversely relative to said contact surface,
- said inner centering elements of said first member being disposed inside said outer centering elements of said second member, said outer centering elements of said first member being disposed outside said inner centering elements of said second member,
- said centering surface of each said inner centering element of said first member being disposed to abut said centering surface of only one adjacently disposed inner centering element of said second member,
- said centering surface of each said outer centering element of said first member being disposed to abut said centering surface of only one adjacently disposed outer centering element of said second member,
- each of said centering elements having remaining transversely extending surfaces in addition to said centering transversely extending surface, said remaining transversely extending surfaces of one member being separated sufficiently in a radial and circumferential direction with respect to adjacent remaining transversely extending surface of the centering element of the other member to allow for expansion without deformation of said centering elements when said coupling is at a maximum operating temperature.
