ABSTRACT:
The saw assembly is provided with a self-contained balancing means for the automatic balancing of the wheel head. In one embodiment, the balancing means includes an annular rotor which is mounted on the wheel head and which contains a vaporizable fluid medium within circumferentially spaced chambers. Heating elements are provided for heating selected chambers in order to vaporize and transfer the balancing medium between chambers via a capillary manifold tube, or pneumatic means is used to transfer the balancing medium. Sensors are provided to sense the rotation of the wheel head and the radial vibration of the wheel head and cutting blade of the saw assembly in order to determine where the wheel head is out-of-balance.
