Description
Technical field
It the utility model is related to a kind of reaction fin, more particularly to a kind of damping reaction fin peculiar to vessel.
Background technology
Common reaction fin is the propulsive performance for improving ship, it is therefore an objective to produces a direction and is turned round with propeller
Revolution flowing in opposite direction is applied to the current in inflow spiral propeller to promote stern.Existing reaction fin structure is
Some reaction fins are installed in fin hub outer surface, and reaction fin is welded on fin hub surface, and not prison welding can influence whole admittedly
Body rigidity, fin hub are arranged on stern post, and reaction fin can produce very big vibrating noise in the process of running, influence to firmly install
Property, reduce service life.
Utility model content
For drawbacks described above, the purpose of this utility model be to provide it is a kind of simple in construction, it is easy to make, shake can be lowered
Dynamic noise, improves firmly installing property, improves the rigidity of reaction fin, a kind of damping reaction fin peculiar to vessel to increase the service life.
Technical scheme is used by for this utility model：
Including stern post and fin hub, the fin hub sleeve is connected on outside stern post, and the fin hub is provided with blade, the fin hub and blade
It is integral and is formed by casting, annular gap is provided between stern post and the fin hub, the fin hub rear and front end is set respectively
There is baffle plate, the baffle plate is welded to connect with fin hub and stern post outer surface, and epoxy is marked with the annular gap.
As the further improvement of above-mentioned technical proposal, the annular gap rear and front end, which is respectively equipped with, to be welded on outside stern post
Annular slab on surface, outside and the baffle plate of the annular slab are welded to connect.
As the further improvement of above-mentioned technical proposal, the thickness of the annular gap is 40-60mm.
As the further improvement of above-mentioned technical proposal, the front elevational sectional of stern post and the fin hub is circular, the stern post
Rear end section with fin hub is polygon.
The utility model has the advantages that：
The utility model is simple in construction, and one is cast as by using fin hub and blade, improves firmly installing property, manufacture
It is convenient, by injecting epoxy in the annular gap between fin hub and stern post, fin hub vibrating noise is reduced, improves reaction fin matter
Amount and rigidity, increase the service life.
