ABSTRACT:
A device for trimming, or removing burrs from, and bevelling, the teeth of gears and pinions comprises means for rotatably driving the gear to be treated, at least one milling head of which the cutter is adapted to engage the lateral edges of the gear teeth, a follower adapted to follow radially the tooth outline of the rotating gear, and means responsive to said follower for moving the cutter in a plane transversely to said gear in order to cause said cutter, in synchronism with the gear rotation and by temporary shape engagement in each hollow between teeth, to remove the burrs from, and bevel, the corresponding tooth edges, said means comprising a bell-crank lever rigid with said follower and co-acting with a slide controlling the milling head for converting the radial movement of said follower into a transverse movement of said milling head in relation to the wheel to be treated, this device comprising if desired two milling heads for treating simultaneously both faces of a same gear.
