Abstract: A method for creating a releasable joint between two components wherein one of the components is elastically deformed by radial compressive forces in such a way that one effective circumferential contour corresponds to the corresponding effective circumferential contour of the other component with a predefined clearance, and the two components are fitted together. After being fitted together, a compressive joint is created by the fact that the deformed component is elastically deformed back by reducing or discontinuing the radial compressive forces. What is used as the elastically deformable component is a hollow body which has multiple cavities in its wall, and the radial compressive forces are exerted on the inner or outer contour of the hollow body located opposite the effective circumferential contour in such a way that their working lines, considered in the circumferential direction, run approximately centeredly through the cavities.

Abstract: An improved connecting rod assembly and method for making a connecting rod wherein the installation of the bearing sleeve members in the large bearing end of the connecting rod is improved. The connecting rod is forged, and then notches are cut in the large bearing end to define a separation plane about which the large bearing end is subsequently separated to form a cap member and a body member. Sleeve bearing members are inserted into the cap member and body member. Free ends of the sleeve bearing members project beyond associated surfaces of the cap and body members a predetermined distance. Upon compressive re-attachment of the cap member to the body member, the free ends of the bearing members are compressed and deformed to provide protrusions that extend into the notch. The protrusions help to prevent rotation of the bearing members relative to the bearing housing.

This telescope assembly contains roller bearings to reduce stiction and prevent torsional losses. The adjustment mechanism includes an adjustable outer race shim composed of two oppositely tapered races moving longitudinally in relation to each other, thereby causing their combined thickness to expand or contract thus allowing the bearing pre-load to be adjustable.

In addition, this collar enables greater geometric latitude on the shape of the inner tube, thereby enabling significant strengthening of the telescoping assembly using light weight materials and lower cost manufacturing processes that hitherto have been unachievable.
