Connecting rod for axial cylinder-type reciprocating piston engine

Claim 1

A connecting rod for an axial cylinder-type reciprocating piston engine which includes a wobble ring, a first spherical bearing means provided at the wobble ring, and a second spherical bearing means provided at the piston of the engine, characterized in that a sheet metal tubular shaft is provided, hollow sheet metal spherical shells are welded at respective ends of said tubular shaft, each of said hollow spherical shells including inner and outer spherical surfaces, the inner spherical surfaces extend radially outwardly with respect to a longitudinal axis of the tubular shaft beyond the respective ends of the tubular shaft and are adapted to respectively cooperate with the first and second bearing means, a pair of retaining ring means are provided for releasably connecting the respective spherical shells to the piston and wobble ring, and in that each of said retaining ring means includes spherical surfaces cooperable with the respective outer spherical surfaces of the hollow spherical shells.
