Abstract
An apparatus for unbalanced compensation of a grinding wheel which is rotatable about an axis of rotation, with compensating weights which are guided rotatably about the axis of rotation of the grinding wheel with symmetrical mass distribution relative to a central plane of the grinding wheel which is perpendicular to the axis of rotation. A positioning mechanism is provided for different angular positionings of the compensating weights. The compensating weights are mounted for rotation through 360.degree. about the axis of rotation at different radii, the product of the mass of each compensating weight and its associated radius being equal to the product of the mass of each other compensating weight and its associated radius.
Claims12
An apparatus for compensating for unbalance in a grinding wheel rotatable about an axis of rotation, comprising:
- first and second compensating weights rotatably disposed with symmetrical mass distribution relative to a central plane of said grinding wheel which is perpendicular to said axis of rotation;
- first and second electric motors having motor shafts to produce different angular positions of said first and second compensating weights, respectively, said motor shafts being concentrically arranged with said axis of rotation;
- and
- first and second rotating mounting sleeves rotatably mounted to guide said first and second compensating weights respectively through 360.degree. about said axis of rotation, said first and second rotating mounting sleeves being drivingly connected to said motor shafts of said first and second electric motors respectively, said compensating weights being disposed at different radii from said axis of rotation so that the product of a mass of each of said first and second compensating weights and an associated radius of said radii is of at least substantially a same magnitude for each of said first and second compensating weights.
An apparatus for compensating for unbalance in a grinding wheel rotatable about an axis of rotation, comprising:
- compensating weights rotatably disposed with symmetrical mass distribution relative to a central plane of said grinding wheel which is perpendicular to said axis of rotation;
- an electric motor associated with each of said compensating weights to produce different angular positions of each of said compensating weights, each said electric motor having a motor shaft concentrically arranged with said axis of rotation;
- and
- a rotating mounting sleeve associated with each of said compensating weights rotatably mounted to guide each of said compensating weights through 360.degree. about said axis of rotation, said rotating mounting sleeve being drivingly connected to said motor shaft of said electric motor associated with each of said compensating weights, each of said compensating weights being disposed at different radii from said axis of rotation so that the product of a mass of each of said compensating weights and an associated radius of said radii is of at least substantially a same magnitude for each of said compensating weights.
