Abstract

1,214,382. Gear-finishing. CARL HURTH MASCHINEN-UND ZAHNRADFABRIK. 9 Sept., 1968 [7 Sept., 1967; 18 Dec., 1967], No. 42775/68. Heading B3K. A machine for finish machining gears by means of a gear-shaped tool 2 e.g. a shaving or rolling tool, comprises a spindle for supporting the workpiece 1 on a table 4 which is integral with or fixed to the machine frame 3 and a circular section tool slide 26 in a circular section guide 20 arranged to provide the tool with depth feed only. The tool mounting means comprises: a support 8 pivotably adjustable about a vertical pin 9 and fixable in adjusted position on the frame 3, a slide guide 20 adjustable towards the work in an inclined slideway 18 of the support 8 and fixable on the support 8, a slide 26 of circular cross-section enclosed in the slide guide 20 and arranged to be fed therein towards and away from the work by a cam 65 and follower 58, and a tool head 37 which is angularly adjustable on the slide 26 to vary the angular relationship 131 between the tool and workpiece, the tool head 37 carrying a tool and tool drive motor 52. Feed of the slide 26 together with the toolhead 37 takes place against the pressure of springs 72 which serve for retracting the slide and tool. The cam 65 and its drive motor 66 are mounted on a lid 60 loaded by springs 74 against the rear end of the slide guide 20 so that feed of the tool can be limited by an adjustable stop member (Fig. 5, not shown) adapted to abut against the toolhead 37, any excess feed being accommodated by rearward displacement of the lid 60 against the action of springs 74. Rollers 30, 31 operate in an inclined groove 29 in the slide 26 to provide a helical or angular motion to the slide and tool during the feed stroke. In an alternative embodiment (Figs. 7, 8, not shown) a single roller mounted on the slide runs in a groove of a member adjustably mounted on the slide guide, the angular disposition of the member being adjustable to vary the helical feed motion of the slide. Motors 52, 66 are preferably hydraulic and their speeds may be regulated in variable interdependence upon each other. Alternatively electrical motors with variable speed transmission may be used. Cam drum 69 mounted coaxially with the cam 65 operates switches 71 controlling the machine cycle.
