Single row spherical bearing

Claim 1

IN A SINGLE ROW SELF-ALIGNING BEARING HAVING INNER AND OUTER RACE RINGS AND A PLURALITY OF ROLLERS THEREBETWEEN MAKING UP A BEARING CAPABLE OF ACCOMMODATING A RADIAL LOAD AND A THRUST LOAD IMPRESSED THEREON AND CAPABLE OF OPERATING WITH THE ROLLERS AND INNER RACE RING THEREOF MISALIGNED RELATIVE TO THE OUTER RACE RING, SAID PLURALITY OF ROLLERS EACH HAVING A RADIUS OF CURVATURE FOR ITS OUTER CIRCUMFERENTIAL SURFACE PROVIDING AN AXIALLY CONVEX CONTOUR, AND WITH SAID OUTER RACE RING HAVING AN AXIALLY CONCAVE SPHERICAL RACEWAY BUT HAVING NO FLANGES AT THE SIDES OF SAID RING TO DEFINE A RACEWAY AND HAVING A RADIUS OF CURVATURE WITH THE ORIGIN THEREOF AT THE AXIAL CENTER OF THE ASSEMBLED BEARING, SAID RADIUS OF CURVATURE OF SAID OUTER RACE RING RACEWAY BEING SUBSTANTIALLY THE SAME AS THE RADIUS OF CURVATURE OF EACH ROLLER SURFACE, THE MEANS IN SAID BEARING TO PRODUCE SAID LOAD CAPABILITY FOR SAID BEARING COMPRISING SAID INNER RACE RING HAVING AN AXIALLY CONCAVE RACEWAY WITH A RADIUS OF CURVATURE SUBSTANTIALLY THE SAME AS THE RADIUS OF CURVATURE OF THE SURFACE OF EACH OF SAID ROLLERS AND HAVING A GUIDE FLANGE AT EACH SIDE THEREOF DEFINING A RACEWAY IN SAID INNER RACE RING, SAID INNER RACE RING HAVING AN AXIAL CENTER, SAID GUIDE FLANGES ON SAID INNER RACE RING BEING SPACED APART A DIMENSION GREATER THAN THE AXIAL LENGTH OF THE ROLLERS AND BEING WITHIN A DIMENSIONAL RANGE WHEREIN THE MINIMUM ALLOWABLE TOTAL OF THE END CLEARANCES BETWEEN A ROLLER AND SAID TWO GUIDE FLANGES IS ONE-TENTH OF AN AXIAL MOVEMENT OF SAID ROLLER IN SAID BEARING IN A DIRECTION RELATIVE TO THE AXIAL CENTER OF SAID INNER RACE RING IF THERE WERE NO GUIDE FLANGES ON THE INNER RACE RING AND THE AXIALLY CONCAVE EXTENDED THE FULL WIDTH OF THE INNER RACE RING MULTIPLIED BY THE ROLLER DIAMETER TO ROLLER LENGTH RATIO, AND WHEREIN THE MAXIMUM ALLOWABLE TOTAL OF THE END CLEARANCES BETWEEN SAID ROLLER AND SAID TWO GUIDE FLANGES ON SAID INNER RACE RING PERMITS ONLY A MAXIMUM ANGLE OF ROLLER-SKEW OF 1 DEGREE FOR SAID ROLLER IN THE INNER RACEWAY BETWEEN SAID TWO GUIDE FLANGES.
