ABSTRACT:
A connecting rod for a radial piston motor including a spherical surface portion, a rod portion and a pad portion having a sliding surface. The spherical surface portion, rod portion and pad portion are formed integrally, and the sliding surface has a bearing alloy attached to its surface by centrifugal casting. An overlay may be provided on the bearing alloy. The connecting rod is produced in a mass production basis by a method including the steps of integrally forming a star-shape cylindrical monolithic blank (18) having a single cylindrical centrally located axial opening and bearing six equally spaced outwardly radiating rod portions (2), each rod portion bearing an integral, substantially spherical surface portion (1) on its distal end; attaching a bearing alloy by centrifugal casting, to the centrally located axial opening in said blank (18); machining the surface of the bearing alloy; and dividing the blank into six pieces constituting six connecting rods. The machined surface of the bearing alloy may be provided with an overlay, such as a Pb-base alloy.
