摘要

The device (1) has an annular locking element (4) i.e. locking washer, and/or a spacer ring (5) arranged between a nut e.g. hexagonal nut (6), and a pulley (3). Two separate, replaceable segments are formed from a portion (29) of an engine shaft (2), where the portion is formed with an external thread. The segments comprise a threaded sleeve (7) that surrounds the shaft at a predetermined location and forms a fixing unit with an internal thread of the nut. The locking element and/or the spacer ring is formed with a cylindrical pipe.
