Assembly of two bodies having distinctly different coefficients of expansion

摘要

Two coaxial bodies of revolution made of materials having distinctly different expansion coefficients are joined together to form an assembly by fixing means comprising at least three resilient brackets of trapezoidal shape, the larger end of each bracket having a flanged edge secured at at least two points by hollow rivets to a metal ring and by bolts extending through the rivets to the body with the higher expansion coefficient, and the smaller end of each bracket being secured by at least one bolt to the body with the lower expansion coefficient in a manner which imposes a cold prestress on the bracket.
