PUSH ROD FOR A CRANK DRIVE MECHANISM

摘要

A push rod for the crank drive of double-acting piston machines which makes simple and rapid disassembly possible. The shaft portion under the influence of the traction forces set up, is subjected to only relatively light tensile stressing or to compressive stressing. The push rod is secured assembled by anchoring screws with expanding shanks along its entire length and is subjected to alternating stressing, under the influence of a compressive stress which at least partially cancels the tensile stress set up during operation.
