Patent ID: 8708622

Claim:
A gearwheel cutting machine ( 10 ), which is designed for machining the tooth flanks of gearwheels ( 1 ), and which comprises chucking means ( 20 ) for chucking a workpiece ( 1 ) to be chucked and a gear cutting tool, characterized in that: the chucking means ( 20 ) comprises: a pinion receptacle ( 22 ) having a central hole ( 25 ) for receiving a shaft ( 2 ) of the workpiece ( 1 ), said pinion receptacle ( 22 ) defining a first planar, ring-shaped flange surface ( 28 ) facing toward a lug part ( 23 ); the lug part ( 23 ) having a central hole ( 24 ) for insertion over the shaft ( 2 ) of the workpiece ( 1 ), said lug part ( 23 ) defining a second, planar ring-shaped flange surface ( 29 ) facing toward the pinion receptacle ( 22 ); and a flat, ring-shaped vibration-damping element ( 21 ), which is situated as the only connection between the first planar, ring-shaped flange surface ( 28 ) and the second planar, ring-shaped flange surface ( 29 ), the lug part ( 23 ) being thus decoupled with respect to vibration from the pinion receptacle ( 22 ) and the gearwheel cutting machine ( 10 ).
