Abstract
A first coupling device is particularly destined for a dispersing apparatus and comprises a first coupling part having a flange and a tubular connecting piece fixed thereto, the connecting piece having at least two borings for receiving one ball each, and a concentrically surrounding, free moving ring. The diameter of the boring is slightly greater than that of the balls, but in the vicinity of the inner surface of the connecting piece, it is slightly smaller so that the balls may in part protrude into the interior of the connecting piece. The lower portion of the ring has an inner circular recess so that, when the ring is raised, the balls may travel backwards into the circular recess. The second coupling part is adapted to be introduced into said connecting piece and has circular recesses for receiving said balls. Another coupling device for the slippage free connection of high speed rotating shafts of dispersing apparatuses comprises two coupling parts which both have six teeth whose flanks are of 60.degree.. Such coupling devices allow a rapid and safe coupling of dispersing equipment to dispersing apparatus without rotational or axial slippage.
