Cage and roller method

Abstract

Abstract IN CAGE AND ROLLER COMBINATIONS SUITABLE FOR OPERATION BETWEEN INNER AND OUTER MEMBERS TO FORM A BEARING, A CAGE GUIDED ON ITS OUTSIDE DIAMETER IS PRODUCED BY FORMING A BLANK HAVING THICKENED RIM PORTIONS AT THE ENDS, RELIEVED RELATIVELY THIN PORTIONS INWARDLY OF THE RIM PORTIONS, THICKENED GUIDING PORTIONS AND OUTWARD RETAINING PORTIONS INWARDLY OF THE RELIEVED PORTIONS AND A RELATIVELY THIN MID-LENGTH PORTION, THEN PUNCHING WINDOWS WITH PARALLEL SIDES FROM THE MID-LENGTH PORTION, THE GUIDING AND OUTWARD RETAINING PORTION AND THE RELIEVED PORTION BUT NOT ENTERING THE RIM PORTIONS, THE WINDOWS BEING RELATIVELY WIDE AT THE ENDS AND RELATIVELY NARROW AT THE MIDDLE, AND THEN COINING THE CROSSBARS DESIRABLY SIMULTANEOUSLY TO FORM LIPS AT THE GUIDING AND OUTWARD RETAINING PORTIONS NEAR THE OUTSIDE WHILE RETAINING PARALLEL SIDES AT THE GUIDING PORTIONS NEAR THE PITCH DIAMETER, AND TO DISPLACE METAL FROM THE MID-LENGTH PORTIONS SO AS TO FORM INWARDLY CONVERGING SIDE WALLS WHICH WILL CLEAR THE ROLLERS AND PREVENT ESCAPE OF THE ROLLERS INWARDLY. THE INVENTION MAY PROVIDE CAGE AND ROLLER COMBINATIONS IN WHICH A SINGLE ROLLER IN A WINDOW IS GUIDED ADJOINING THE PITCH CIRCLE NEAR THE END, THE GUIDING PORTION OUTWARDLY CONVERGES TO RETAIN THE ROLLER AGAINST OUTWARD MOTION, AND THE WINDOW AT THE END TERMINATES SHORT OF THE RIMS.
