Abstract
PURPOSE: To prevent a journal part of a soild coupling from being damaged by attaching a low-alloy steel sleeve, which is divided along its periphery, to the journal part.
CONSTITUTION: A low-alloy steel sleeves 4 consist of two half-cylindrical parts and are provided with convex edges 9a and concave edges 9b at their coupling edges. These coupling edges 9a and 9b are of double-tail form so that the coupling edges withstand the centrifugal force induced in the sleeves 4 by the rotation. These sleeves are fitted to a journal part 2 of a rotor 1. In this case, the diameter d of a rotor shaft between the journal part 2 and a coupling 5 is formed a few milimeters smaller than the diameter D of the shaft in way of the journal 2 so that the divided sleeves 4 can be assembled here prior to be inserted to the journal 2.
