An anti-fishnet oil lubricating sealed-in device for ship's stern shaft. The part which guards against fishnet twining works in the following way: Anti-fishnet drive screw is used to revolve anti-fishnet moving ring together with stern shaft. When fishnet twines around damp ring assembly it is blocked, and then ground by two carbide layers between the surface of friction to prevent the ground fishnet from entering. And because of the compensation effect of anti-fishnet spring assembly, the two carbide layers always keep appressed so that it is difficult for the ground fishnet to enter. The oil lubricating sealed-in device consists of moving ring which rotates with stern shaft, spring assembly, compensating ring and static ring. |
