摘要

Connecting device for a rotor (10) of an electric motor (3) with a shaft (4), in particular a crankshaft of a hermetic refrigeration compressor, in which between the rotor (10) and the shaft (4) is arranged a sleeve (11) and the parts of the rotor (10), the sleeve (11) and the shaft (4) are added together axially, to at least a part of the sleeve (11) in a bore (12) of the rotor (10) and at least a part of the shaft (4) in the sleeve (11) is received, characterized in that the bore (12) of the rotor (10) a conical widening (16) or increase in diameter and a sleeve (11) are used, whose inside diameter by a predetermined first value (x) is greater than the outside diameter of the shaft (4) and their outside diameter by a predetermined second value (y) is greater than the diameter of the bore (12), and the sleeve (11) on the shaft (4) slides, the axially relative to the shaft (4) and then holds the rotor..
