Achslagerung in einem Güterwagen

摘要

In a goods wagon axle bearing assembly of the type provided with a sealing device (20) at its axially outer end, the sealing device comprises a rigid, non-rotating shield (21). Integrated with the sealing device (20) is a current generator, consisting of a magnetised impulse generating ring (25) rotatably fast with one of the rotating parts (12) of the bearing, and a coil (24) operatively facing the magnetised impulse ring and secured to the non-rotating shield (21). The current induced in the coil (24) is supplied to a current drain point on the same goods wagon.
