Abstract
The device serves for the end face, angularly true driving of a pre-toothed workpiece (21) clamped between work centers by the rotating work spindle (3) of a tooth flank grinding machine. It takes place by means of a wobble plate (10) connected without play to the work spindle by way of the work arbor (1), the intermediate disc (17) and the cylindrical steel rollers (13, 18), the surface of which said wobble plate which contacts the workpiece end face (29) being according to the invention coated with galvanically bonded hard material grains (24).
Claims8
A device for end face transmission of a driving torque of a work spindle (3) of a machine tool, to a rotating workpiece (21), comprising a work arbor (1) firmly attached to said spindle (3) and a spring loaded work center (26) axially displaceably located therein without play, wherein between said work arbor (1) and said workpiece (21) torsionally and axially rigidly connected without play to said work arbor (1) a wobble plate (10) is arranged, said wobble plate (10) having a surface contacting the workpiece end face (29) and being coated with hard material grains (24) and wherein said wobble plate and said work arbor are torsionally and rigidly connected to one another by means of a pliable, axially elastic thin-walled tube.
