Abstract
An arrangement to devibrate a hand-held, compressed air-driven rotary grinding machine with vertical spindle. A grinding machine equipped with an unbalanced and unequally worn grinding wheel vibrates severely and will injure the operator. To avoid vibration reaching the hands of the operator, the drive unit (2) with its integral spindle (13) is supported by shock and vibration-absorbing elements (3, 4, 4', 16) in the outer case (1) where it is able to move in three dimensions. The working movement (compression-elongation as well as sideways) of the elements is never exceeded by the amplitude of the vibration that occurs when the machine runs at a normal working rotational speed, which is much higher than the critical resonance speed. The drive unit (2) is very lightweight in relation to the outer case (1) and to the grinding wheel (5, 6, 7). As a result of this, the grinding wheel will centre itself automatically when the critical resonance speed is passed. Compressed air is supplied to the motor through a flexible hose (10).
