Abstract
Power honing/grinding machine for the finishing of cylindrical gears with external toothing tools, comprising a workpiece clamping unit having a first electrospindle rotatable about a first axis, and a tool-holder unit having a second electrospindle rotatable about a second axis, in which the movement of rotation of the second electrospindle about the second axis is synchronized with the movement of rotation of the first electrospindle about the first axis, wherein the first electrospindle has an external stator and an internal rotor and the second electrospindle has an internal stator and an external rotor.
Claims8
Power honing/grinding machine for the finishing of cylindrical gears with external toothing tools, comprising:
- a workpiece clamping unit having a first electrospindle rotatable about a first axis, wherein the first electrospindle has an external stator and an internal rotor and a first moment of inertia with respect to the first axis;
- a tool-holder unit having a second electrospindle rotatable about a second axis, wherein the second electrospindle has an internal stator and an external rotor and a second moment of inertia with respect to the second axis,
- wherein the movement of rotation of the second electrospindle about the second axis is synchronized with the movement of rotation of the first electrospindle about the first axis, and
- wherein the second moment of inertia is sufficiently greater than the first moment of inertia, whereby rotational disturbances of the first electrospindle are prevented from being transmitted to the second electrospindle.
