Abstract
A generally cylindrical metallic member of hardened steel, especially a race for a journal bearing, is fitted into or around a supporting element of relatively deformable metal, such as structural steel, having a face perpendicular to the cylinder axis. The hardened metallic member has a peripheral groove into which some of the material of the supporting element is extruded by indenting the perpendicular face, preferably by a circular array of notches.
Claims8
In a journal bearing including a pair of coaxial annular races of hardened steel separated by a set of rotary bodies, one of said races having a cylindrical surface remote from said bodies, and a supporting element of relatively deformable metal for said one of said races, said supporting element having an annular surface coaxial with said cylindrical surface and in contact therewith,
- the improvement wherein said one of said races is formed on said cylindrical surface with a peripheral groove of rectangular cross-section overlain by said annular surface, said groove being occupied over at least part of its length and over its entire width by metal from said supporting element extruded into same, the extruded metal transmitting axial forces between said element and said one of said races while preventing any relative axial shifting thereof.
