Propeller Shaft Earthing System patented continuous slip ring cleaning device the rotating propeller shaft and the ship s hull.

800 series available with AEGISTM shaft grounding rings. The encoder need to be pre-prepared with a special encoder shaft in order to permit the mounting of a SGR. As the SGR is somewhat subject to wear are they always mounted outside the encoders enclosure [Figure 5] and can therefore easily be replaced. Thus preventing cur-

Propeller Shaft Grounding System consists of the following Slip Ring - Elevated silver band reduce dirt for best possible contact. Brush Holders - Double and single brush holders for grounding and measurement. Strong springs for proper brush pressure Silver slip band - Reliable contact. Easy installation

To protect the bearings from harmful currents the bearings are electrically insulated and the shaft equipped with an earthing device. The earthing devices that are normally used are based on metal to metal contact which requires a lot of maintenance, or based on micro-fibers which are costly and restricted by export control regulations.

US 5,454,724 A discloses an electrical machine having an input shaft and an earthing device for electrically earthing the input shaft, the earthing device having a sliding contact for making contact with the input shaft. A disadvantage of this is that the earthing device has a comparatively high resistance, and therefore electrostatic charges on the input shaft are opposed by a comparatively
