Abstract
The method and the device provide for the balancing of rotating bodies, in particular for balancing the drum of a reproduction unit such as a roller of a printing plate exposure device. At least one weight element is provided as a balancing element that can be repositioned along a predetermined movement path, especially a movement path running at a constant radial distance from the axis of rotation of the rotating body. The weight element compensates for imbalances and it can be fixed in different balancing positions by interlocking engagement.
Claims28
A method of balancing a rotating body, which comprises:
- providing a rotating body with a given axis of rotation and having a predetermined movement path on the rotating body;
- repositioning at least one weight element along the predetermined movement path;
- selectively fixing the weight element in a balancing position by means of interlocking engagement;
- catching the weight element for moving along the predetermined movement path by a catching fixture;
- and
- introducing a catching member into a blind hole formed in the weight element, the catching member and the blind hole being offset in relation to one another in a radial direction of the rotating body such that the offset is smaller than a radius of the blind hole.
A balancing assembly, comprising:
- a rotating body having a defined axis of rotation and formed with a predetennined movement path;
- at least one weight element having a blind hole formed therein, said weight element positioned along said predetermined movement path and selectively fixable in a plurality of balancing positions by interlocking engagement with said rotating body;
- and
- a catching fixture having a catching member for catching said weight element for movement along said predetermined movement path, said catching member being introduced into said blind hole said catching member and said blind hole are offset in relation to one another in a radial direction of said rotating body and said offset being smaller than a radius of said blind hole.
