| 摘要 |
The invention relates to a device on a controllable-pitch marine propeller, in particular a cycloidal marine propeller, for protecting the same against corrosion. The invention is characterized in that insulating surfaces or insulating parts are arranged at the bearing points on the propeller blades. The insulating surfaces or insulating parts electrically insulate the propeller blades from the bearing supports (bearing housings) or reduce the current transfer to the latter by their high electrical resistance to values which are harmless for electrolytic corrosion. <IMAGE> |
