Abstract
The present invention relates to a kind of damping reaction fin peculiar to vessel.Including stern post and fin hub, the fin hub sleeve is connected on outside stern post, the fin hub is provided with blade, the fin hub is integral with blade and formed by casting, annular gap is provided between stern post and the fin hub, the fin hub rear and front end is respectively equipped with baffle plate, and the baffle plate is welded to connect with fin hub and stern post outer surface, and epoxy is marked with the annular gap.The present invention is simple in construction, and one is cast as by using Fin hubs and blade, improves firmly installing property, it is easily manufactured, by injecting epoxy in the annular gap between Fin hubs and stern post, reduce Fin hub vibrating noises, reaction fin quality and rigidity are improved, is increased the service life.
Description
Technical field
The present invention relates 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 hubs outer surface, and reaction fin is welded on Fin hubs surface, and not prison welding can influence whole admittedly
Body rigidity, Fin hubs are arranged on stern post, and reaction fin can produce very big vibrating noise in the process of running, and influence is firmly installed
Property, reduce service life.
The content of the invention
It is easy to make it is an object of the invention to provide one kind is simple in construction for drawbacks described above, can reducing vibration make an uproar
Sound, improves firmly installing property, improves the rigidity of reaction fin, a kind of damping reaction fin peculiar to vessel increased the service life.
It is for this technical solution adopted in the present invention：
Including stern post and fin hub, the fin hub sleeve is connected on outside stern post, and the fin hub is provided with blade, and the fin hub is one with blade
Entirety is simultaneously formed by casting, annular gap is provided between stern post and the fin hub, the fin hub rear and front end is respectively equipped with gear
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 circle, the stern post
Rear end section with fin hub is polygon.
It is an advantage of the invention that：
The present invention is simple in construction, and one is cast as by using Fin hubs and blade, improves firmly installing property, easily manufactured, leads to
Cross and epoxy is injected in the annular gap between Fin hubs and stern post, reduce Fin hub vibrating noises, improve reaction fin quality and firm
Property, increase the service life.

Embodiment
A kind of damping reaction fin peculiar to vessel, including stern post 1 and fin hub 2, the fin hub 2 are socketed in outside stern post 1, the fin hub
2 are provided with blade, and the fin hub 2 is integral with blade and formed by casting, and ring is provided between the stern post 1 and fin hub 2
Shape gap, the rear and front end of fin hub 2 is respectively equipped with baffle plate 3, and the baffle plate 3 is welded to connect with fin hub 2 and the outer surface of stern post 1,
Epoxy 4 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, is welded on stern post 1
Annular slab 5 on outer surface, outside and the baffle plate 3 of the annular slab 5 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 the stern post 1 and fin hub 2 is circle, the tail
The rear end section of post 1 and fin hub 2 is polygon.
