ROLLING BEARING Russian patent published in 2005 - IPC

FIELD: mechanical engineering, particularly rolling bearings and rivets.

SUBSTANCE: rolling bearing comprises racers, rolling members and retainer. Retainer includes two halves connected by rivets, which are installed in coaxial orifices formed in pads of each retainer halve. Rivet includes rod member having length of not more than summary thickness of retainer halves to be connected, set head and closing head formed of axial profiled fixing pin. Shape and dimensions of rod member and axial fixing pin correspond to that of coaxial retainer orifices and rivet bar. Fixing pin profile is changed along rivet axis. Fixing pin profile apexes are located in axial rivet plane or lie on helical rod member line. Valleys thereof are spaced a distance equal to radial rivet bar dimensions from rivet axis. Summary length of rod member and axial fixing pin exceeds summary thickness of retainer halves to be connected for value necessary for forming closing head of the rivet.

EFFECT: possibility of retainer riveting automation during rolling bearing assembling.
