Definitions

  • the invention relates to a balancing device for rotary tools which are subject to wear, for example grinding wheels, in which an annular preferably dovetail-shaped groove may be provided in the face of a flange on each side of the tool for receiving adjustable weights to compensate for out-of-balance, additional unbalancing as occurring during operation as a result of wear of the tool being periodically balanced by smaller additional weights which are likewise displaceably secured to the flange.
  • At least one of the two anges comprises a groove in addition to the one usually provided, such additional groove being concentric and smaller in diameter and cross-section than the conventional groove, and housing at least two additional weights adapted to be displaced to compensate unbalance occurd, 2,958,155 Patented Nov.. l, 1960 ring spasmodically during operation.
  • the ratio of the cross-section of the smaller annular groove to that of the larger annular groove is between 1:2 to 1:10 and preferably between 1:3 to 1:5.
