<p>Rotation device that can be attached to a working machine or to a tool attached to said machine comprising a lower plate (5) and an upper plate (2), (14), (23) said plates having the same direction and installed to a distance from each other, comprising a bearing between said plates in order to rotate them in relation to each other and a possible rotating device (3) in order to rotate said plates in relation to each other. The removal of the bearing clearance between the plates and/or an interlocking of the reciprocal rotation are adjusted in connection with the bearing between said plates in which case said interlocking can be achieved by arranging a compression between bearing surfaces which compression prevents the reciprocal rotation of said plates and the removal of the bearing clearance can be achieved by arranging an essentially smaller compression than the previous compression between the bearing surfaces.</p> |
