Abstract
A grinding wheel having a hollow balance ring embedded in the grinding wheel material about the arbor hole. Steel shot partially fills the balance ring and automatically moves to a position to dampen any rotating imbalance in the grinding wheel both when it is new and as it wears. The balance ring can also function as a substitute for the conventional fracture or safety ring in the grinding wheel.
Claims7
A combination comprising:
- a grinding wheel adapted to be rotated about an axis, the grinding wheel including a mass of abrasive material;
- a hollow balance ring embedded in the grinding wheel material, the balance ring being formed about a central axis coinciding with the axis of rotation of the grinding wheel, the balance ring having an endless, internal annular channel;
- and
- a plurality of steel shot, partially filling the annular channel so as to move to a position to dampen any dynamic imbalance in the grinding wheel as it is being rotated about the axis of rotation.
