Abstract

1,227,636. Jointing; making shafts, print drums. NATIONAL CASH REGISTER CO. 25 Sept., 1969 [27 Sept., 1968], No. 47223/69. Headings B3A and B3V. A drum, particularly a printing drum, is joined to a shaft by shrink fitting an integral hardened contacting surface of the drum on to a hardened external contacting surface of the shaft after depositing on one of the surfaces a layer of softer metal. The drum and shaft are preferably of steel and the layer of soft metal copper which is first deposited as a layer about 0À005 inch thick and then ground to a thickness of about 0À0005 inch. The shaft 16 is made by machining from vacuum melt steel, heat treated and stress relieved then finish machined. The shaft is packed in charcoal to prevent decarburization during heat treatment, which produces an austenitic steel. This is followed by quenching in an oil bath. The shaft is examined for eccentricity or run out, any run out being corrected by selective loading of the shaft, and then tempered at 450‹ F. in a forced air furnace for 2 hours, stabilized at - 120‹ F. for 2 hours and then tempered, unloaded, at 450‹ F. for 2 hours. The hardness of the external contacting surface 18 should now be 58 to 60 Rockwell. The shaft is ground, the layer of copper applied to the surface and ground to the desired thickness. The drum is made from tool steel of wall thickness 0À152 inch with a centre portion 32 of 0À5 inch thickness and heat treated to harden it. The diameter of portion 32 is ground to be 0À004 inch less than the finished diameter of the surface 18 and the two interfitted by freezing the shaft to - 120‹ F. and heating the drum to 450‹ F. Pulleys 22 are shrink fitted to driving surfaces 20 on the shaft by conventional techniques and rotors 28 are shrink fitted to each end.
