Abstract

906,651. Making dog-clutches; rolling gear teeth. ZAHNRADFABRIK FRIEDRICHSHAVEN A.G. Dec. 9, 1958 [Jan. 28, 1958], No. 39747/58. Classes 83 (2) and 83 (4). In a method of making internal and external profiles on a workpiece e.g. clutch teeth for stepped change-speed gears, the profile of the workpiece is formed by rough cutting machining and is relieved by cold-rolling with a tool having at least one tooth profile whose teeth are of a pitch corresponding to those required on the workpiece, the tool and the workpiece being radially displaceable relatively to each other. A roller-tool 19, Fig. 1, is carried on a driven spindle 15 centred at one end and mounted in a bracket 13 at the other, the whole assembly being slidable on a slide 11 towards a workpiece 2, 3 on a centred mandrel 7. The slide 11 is moved by a pressure medium device which also exerts the radial working pressure. The clutch rim 2 of the workpiece is initially rough machined to toothed profile and recesses 45, Fig. 5 (not shown), are formed at the base of the teeth to admit material flowing during subsequent rolling by the tool 19 to form external teeth of a clutch dog-rim. The tool may have a pair of rolling rims for the simultaneous relief-rolling of more than one toothed rim on a workpiece. Individual teeth 41 on the tool are tapered in the direction of the width for producing the type of profile indicated in Figs. 6 and 7 (not shown), while the teeth 42 (Fig. 3, not shown) are thicker than the teeth to be formed on the workpiece and produce the form of profile shown at Fig. 8. Teeth 46, 47, Fig. 4 (not shown) may alternatively be provided on a similar tool. In rolling teeth internally on a rough-cut annular dog-rim 21 of a gear selector sleeve 22, Fig. 2, the workpiece 22 is pressed radially, by a roller 29 mounted on a slide 33, against teeth 23 of a tool 25 mounted on a driven spindle 27.
