Apparatus for compensating unbalance in rotating bodies

Claim 1

AN APPARATUS FOR COMPENSATING UNBALANCES IN ROTATING BODIES, PARTICULARLY GRINDING WHEELS, COMPRISING A CYLINDRICAL HOUSING RELEASABLY SECURED TO A ROTATING BODY TO BE BALANCED, AN OPERATING CAP DISPOSED COAXIALLY WITH AND ADJACENT TO SAID HOUSING, TWO INTERNALLY TOOTHED RINGS SPACED AXIALLY FROM EACH OTHER AND RIGIDLY SECURED IN SAID HOUSING, A FIRST PLANET WHEEL DISPOSED IN SAID HOUSING AND MESHING WITH ONE OF SAID INTERNALLY TOOTHED RINGS, A SECOND PLANET WHEEL DISPOSED IN SAID HOUSING AND MESHING WITH THE OTHER OF SAID INTERNALLY TOOTHED RINGS, A SHAFT EXTENDING AXIALLY THROUGH SAID HOUSING AND THROUGH SAID OPERATING CAP, A SLEEVE DISPOSED COAXIALLY WITH AND SURROUNDING SAID SHAFT, A FIRST TOOTHED WHEEL KEYED TO SAID SHAFT AND MESHING WITH SAID FIRST PLANET WHEEL, A SECOND TOOTHED WHEEL KEYED TO SAID SLEEVE AND MESHING WITH SAID SECOND PLANET WHEEL, EACH OF SAID PLANET WHEELS INCLUDING A BALANCING MASS, A FIRST GEAR WHEEL KEYED TO SAID SLEEVE AND DISPOSED WITHIN SAID OPERATING CAP, A SECOND GEAR WHEEL KEYED TO SAID SHAFT AND DISPOSED WITHIN SAID OPERATING CAP, SAID SECOND GEAR WHEEL THUS ROTATING WITH SAID FIRST TOOTHED WHEEL, SAID HOUSING HAVING A NECK PORTION OF REDUCED DIAMETER A THIRD GEAR WHEEL SECURED TO THE OUTER SURFACE OF AND ROTATING WITH SAID NECK PORTION OF SAID HOUSING, A PLANET CAGE DISPOSED COAXIALLY WITH SAID ROTATABLY ABOUT SAID SLEEVE, SAID PLANET CAGE INCLUDING A PLURALITY OF SECOND SHAFTS DISPOSED PARALLEL TO THE LONGITUDINAL AXIS OF SAID SHAFT, A THIRD INTENALLY TOOTHED RING SECURED TO THE INNER SURFACE OF SAID OPERATING CAP, A FIRST ADJUSTING RING AND A SECOND ADJUSTING RING ROTATABLY MOUNTED IN AND ACCESSIBLE FROM THE OUTSIDE OF SAID OPERATING CAP, SAID FIRST ADJUSTING RING INCLUDING A FOURTH INTERNALLY TOOTHED RING, SAID SECOND ADJUSTING RING INCLUDING A FIFTH INTERNALLY TOOTHED RING, A FIRST GROUP OF THIRD PLANET WHEELS ROTATABLY MOUNTED ON SAID SECOND SHAFT AND MESHING WITH SAID THIRD GEAR WHEEL AS WELL AS WITH SAID THIRD INTERNALLY TOOTH RING, A SECOND GROUP OF FOURTH PLANET WHEELS ROTATABLY MOUNTED ON SAID SECOND SHAFTS AND MESHING WITH SAID FIRST GEAR WHEEL AS WELL AS WITH SAID FOURTH INTERNALLY TOOTHED RING OF SAID FIRST ADJUSTING RINGS, AND A THIRD GROUP OF FIFTH PLANET WHEELS ROTATABLY MOUNTED ON SAID SECOND SHAFT AND MESHING WITH SAID SECOND GEAR WHEEL, AS WELL AS WITH SAID FIFTH INTERNALLY TOOTHED RING OF SAID SECOND AJDUSTING RING, SO THAT THE UNBALANCE IS COMPENSATED BY SAID BALANCING MASSES OF SAID FIRST AND SECOND PLANET WHEELS BY FIRST DETERMINING THE ANGULAR POSITION OF SAID UNBALANCE BY JOINTLY TURNING SAID TWO BALANCING MASSES IN THE SAID DIRECTION OF ROTATION AND THEREAFTER COMPENSATING FOR SAID UNBALANCE BY TURNING SAID BALANCING MASSES IN OPPOSITE DIRECTIONS OF ROTATION RELATIVE TO EACH OTHER BY OPERATION OF SAID ADJUSTING RINGS.

Claim 2

AN APPARATUS FOR COMPENSATING UNBALANCES IN ROTATING BODIES, PARTICULARLY GRINDING WHEELS, COMPRISING A CYLINDRICAL HOUSING RELEASABLY SECURED TO A ROTATING BODY TO BE BALANCED, AN OPERATING CAP DISPOSED COAXIALLY WITH AND ADJACENT TO SAID HOUSING, TWO INTERNALLY TOOTHED RINGS SPACED AXIALLY FROM EACH OTHER AND RIGIDLY SECURED IN SAID HOUSING, A FIRST PLANET WHEEL DISPOSED IN SAID HOUSING AND MESHING WITH ONE OF SAID INTERNALLY TOOTHED RINGS, A SECOND PLANET WHEEL DISPOSED IN SAID HOUSING AND MESHING WITH THE OTHER OF SAID INTERNALLY TOOTHED RINGS, A SHAFT EXTENDING AXIALLY THROUGH SAID HOUSING AND THROUGH SAID OPERATING CAP, A SLEEVE DISPOSED COAXIALLY WITH AND SURROUNDING SAID SHAFT, A FIRST TOOTHED WHEEL KEYED TO SAID SHAFT AND MESHING WITH SAID FIRST PLANET WHEEL, A SECOND TOOTHED WHEEL KEYED TO SAID SLEEVE AND MESHING WITH SAID SECOND PLANET WHEEL, EACH OF SAID PLANET WHEELS INCLUDING A BALANCING MASS, A FIRST GEAR WHEEL KEYED TO SAID SLEEVE AND DISPOSED WITHIN SAID OPERATING CAP, A SECOND GEAR WHEEL KEYED TO SAID SHAFT AND DISPOSED WITHIN SAID OPERATING CAP, SAID SECOND GEAR WHEEL THUS ROTATING WITH SAID FIRST TOOTHED WHEEL, SAID HOUSING HAVING A NECK PORTION OF REDUCED DIAMETER A THIRD GEAR WHEEL SECURED TO THE OUTER SURFACE OF AND ROTATING WITH SAID NECK PORTION OF SAID HOUSING, A PLANET CAGE DISPOSED COAXIALLY WITH SAID ROTATABLY ABOUT SAID SLEEVE, SAID PLANET CAGE INCLUDING A PLURALITY OF SECOND SHAFTS DISPOSED PARALLEL TO THE LONGITUDINAL AXIS OF SAID SHAFT, A THIRD INTENALLY TOOTHED RING SECURED TO THE INNER SURFACE OF SAID OPERATING CAP, A FIRST ADJUSTING RING AND A SECOND ADJUSTING RING ROTATABLY MOUNTED IN AND ACCESSIBLE FROM THE OUTSIDE OF SAID OPERATING CAP, SAID FIRST ADJUSTING RING INCLUDING A FOURTH INTERNALLY TOOTHED RING, SAID SECOND ADJUSTING RING INCLUDING A FIFTH INTERNALLY TOOTHED RING, A FIRST GROUP OF THIRD PLANET WHEELS ROTATABLY MOUNTED ON SAID SECOND SHAFT AND MESHING WITH SAID THIRD GEAR WHEEL AS WELL AS WITH SAID THIRD INTERNALLY TOOTH RING, A SECOND GROUP OF FOURTH PLANET WHEELS ROTATABLY MOUNTED ON SAID SECOND SHAFTS AND MESHING WITH SAID FIRST GEAR WHEEL AS WELL AS WITH SAID FOURTH INTERNALLY TOOTHED RING OF SAID FIRST ADJUSTING RINGS, AND A THIRD GROUP OF FIFTH PLANET WHEELS ROTATABLY MOUNTED ON SAID SECOND SHAFT AND MESHING WITH SAID SECOND GEAR WHEEL, AS WELL AS WITH SAID FIFTH INTERNALLY TOOTHED RING OF SAID SECOND AJDUSTING RING, SO THAT THE UNBALANCE IS COMPENSATED BY SAID BALANCING MASSES OF SAID FIRST AND SECOND PLANET WHEELS BY FIRST DETERMINING THE ANGULAR POSITION OF SAID UNBALANCE BY JOINTLY TURNING SAID TWO BALANCING MASSES IN THE SAID DIRECTION OF ROTATION AND THEREAFTER COMPENSATING FOR SAID UNBALANCE BY TURNING SAID BALANCING MASSES IN OPPOSITE DIRECTIONS OF ROTATION RELATIVE TO EACH OTHER BY OPERATION OF SAID ADJUSTING RINGS.
