Abstract (en)

[origin: WO2016000933A1] The invention relates to securing devices for running wheels (30) of compressors on driveshafts (10), having a driveshaft (10) with an axial portion (32), which has an outer thread (34), and a running wheel (30), which is pretensioned axially against a stop (20) formed on the driveshaft (10) by means of a securing nut (36) screwed onto the outer thread (34) of the driveshaft (10). In order to prevent a torsion of the shaft as much as possible, a contour (38) is formed on an axial end (37) from which the running wheel (30) can be pushed onto the driveshaft (10). A corresponding wrench, via which the torques can be directly received, can be plugged into said contour when tightening the securing nut (36).
