Abstract

1433995 Intermittent toothed gearing UMC INDUSTRIES Inc 8 April 1974 15471/74 Heading F2Q In an indexing apparatus continuous rotation of an input shaft 3 is converted into intermittent rotation of an output shaft 13 by a mechanism comprising a grooved cam 4 fast on the input shaft 3 engaging roller followers 11 on radial spindles of a follower hub 12 fast on the output shaft 13. The arrangement is such that the grooved cam 4 has bevelled side ribs 21, 22 which during each dwell period, between indexing movement, engage the preceding and succeeding rollers 19, 20, the intermediate, i.e. indexed, roller 17 being freely i.e. inactively accommodated with clearance in the central cam groove 10 during the dwell period period. During the period of each indexing movement at the cam indexing point 23 the intermediate roller and one of said preceding and succeeding rollers are in engagement with relevant cam surfaces 24-30 to eliminate backlash and ensure very accurate indexing movement. The cam 4 is mounted with some preloading with respect to the follower hub 12 to ensure some pressure loading between the cam and hub roller followers during both the index and dwell cycles. The central cam groove 10 may be widened to accommodate more than one indexed follower rollers therein at a time.
