Printing cylinder assembly

Abstract

Abstract TION FOR A PRESS-FIT ON THE FIRST SHOULDER PORTION. THE INNER RACE OF THE SECOND BALL BEARING WILL PASS OVER THE SHAFT END FOR A PRESS-FIT ON THE SECOND SHOULDER PORTION. THE OUTER CIRCUMFERENCE OF THE CYLINDER IS CONCENTRIC WITH THE LONGITUDINALLY ALIGNED ROTATIVE AXES OF THE BALL BEARINGS TO PROVIDE A PRECISELY IN-ROUND CYLINDER DIAMETER FOR ACCURATE PRINTING. THE INTERMEDIATE SHAFT PORTION HAS A CROSSSECTIONAL DIMENSION LARGER THAN THE SECOND SHOULDER PORTION TO PROVIDE A STOP ABUTMENT AGAINST WHICH THE INNER RACE OF THE SECOND BALL BEARING IS POSITIONED. THE SHAFT HAS A PORTION ADJACENT TO THE FIRST SHOULDER PORTION AND ON THE OPPOSITE SIDE OF THE FIRST SHOULDER PORTION FROM THE INTERMEDIATE SHAFT PORTION TO PROVIDE A STOP ABUTMENT AGAINST WHICH THE INNER RACE OF THE FIRST BALL BEARING IS POSITIONED. A PRINTING CYLINDER ASSEMBLY INCLUDING A SHAFT HAVING LONGITUDINALLY AND AXIALLY SPACED FIRST AND SECOND SHOULDER PORTIONS WITH AN INTERMEDIATE SHAFT PORTION THEREBETWEEN, THE SECOND SHOULDER PORTION BEING LOCATED NEARER TO THE SHAFT END, AND THE FIRST SHOULDER PORTION BEING PROVIDED WITH A CROSS-SECTIONAL DIMENSION LARGER THAN THAT OF THE SECOND SHOULDER PORTION AND INTERMEDIATE SHAFT PORTION, AND THE SECOND SHOULDER PORTION BEING PROVIDED WITH A CROSS-SECTIONAL DIMENSION LARGER THAN THE SHAFT END. THE PRINTING CYLINDER IS PROVIDED WITH A LONGITUDINAL PASSAGE THERETHROUGH THAT RECEIVES THE SHAFT. FIRST AND SECOND BALL BEARINGS ARE CARRIED BY OPPOSITE ENDS OF THE CYLINDER WITH THEIR ROTATIVE AXIS IN LONGITUDINAL ALIGNMENT, THE OUTER RACES OF THE BALL BEARINGS BEING FIXED TO THE CYLINDER. THE INNER RACE OF THE FIRST BALL BEARING IS PROVIDED WITH A CROSSSECTIONAL DIMENSION LARGER THAN THAT OF THE INNER RACE OF THE SECOND BALL BEARING AND ONLY SLIGHTLY SMALLER THAN THAT OF THE FIRST SHOULDER PORTION. THE INNER RACE OF THE SECOND BALL BEARING IS PROVIDED WITH A CROSS-SECTIONAL DIMENSION ONLY SLIGHTLY SMALLER THAN THAT OF THE SECOND SHOULDER PORTION YET LARGER THAN THAT OF THE SHAFT END, WHEREBY THE INNER RACE OF THE FIRST BALL BEARING WILL PASS OVER THE SHAFT END, SECOND SHOULDER PORTION AND INTERMEDIATE SHAFT POR-
