Abstract

998,375. Rollers. MOUNT HOPE MACHINERY Ltd. June 25, 1964, No. 26234/64. Heading F2U. A curved or straight sectional roller consists of a spindle 10 carrying a series of annular spool elements 12 with end clearances 22, the spools in turn carrying abutting sleeve sections 40, 42 forming a continuous outer surface and with their joints 48 axially displaced from the spool clearance gaps 22. The spools 12 are mounted on ball-bearings 16 whose inner races 24 are secured between spacers 23 by locking pins 32 with heads received in a keyway 28 in spindle 10. As shown, the joint between adjacent sleeve sections is of stepped form with the outer portions 62 cemented together, and the inner end portions 50 of one of each pair of adjacent sleeves also cemented to its spool element 40 or 42. In other arrangements the sleeve joints are of the simple butt-type, Fig. 4 (not shown), while in other stepped forms plain or screw-threaded metallic reinforcing rings are incorporated in the joints, Figs. 6 and 7 (not shown). The sleeves are compressed axially by end caps 47, but in the case of a curved roller these are preferably so arranged that there is substantially no compression in the outer convex side of the roller. The arrangement permits ready replacement of any worn sleeve sections.
