Abstract
The utility model discloses a kind of propeller for ship outboard machine, which is made of fin-shaped protrusion, hollow hub, blade.The propeller is the junction in propeller shank and hollow hub, it blade is increased width protrudes from the edge of hollow hub and install simultaneously and have the fin-shaped of certain thickness and length raised for same entirety with blade, hollow hub and extend to inside hollow hub, depending on installation number is as needed.Fin-shaped protrusion can be Split type structure with hollow hub and blade, using welding connecting mode.Advantageous effect is：Since the edge that the junction blade increase width of propeller shank and hollow hub protrudes from hollow hub is mounted with that fin-shaped is raised and extends to inside hollow hub simultaneously, it is re-used the current flowed through near hollow hub during propeller works, hydraulic pressure approaches inside and outside hollow hub, thus can effectively stop the formation in hub whirlpool.
Description
Technical field
The utility model is related to a kind of propellers on ship outboard machine.
Background technology
At present, well known ship outboard machine propeller is made of propeller hub, blade.The shape of propeller hub has mounted on groomed oar
Hollow hub on axis, the solid propeller hub also formed in solid paddle shaft.Wherein hollow hub is in propeller works
Also it is poor that water flow pressure can be generated, form hub whirlpool, reduce propulsive efficiency.
The content of the invention
In order to overcome above-mentioned deficiency, the utility model provide it is a kind of can prevent hollow hub hub volute into ship outboard machine
Use propeller.
The utility model realizes foregoing invention purpose using following technical scheme
The propeller is the junction in propeller shank and hollow hub, and blade, which is increased width, protrudes from hollow hub
Edge is installed simultaneously to be had the fin-shaped of certain thickness and length protrusion for same entirety with blade, hollow hub and extends to hollow
Inside propeller hub, depending on installation number is as needed.Fin-shaped protrusion can also be Split type structure with hollow hub and blade.
The beneficial effects of the utility model are：
The edge of hollow hub is protruded from since blade is increased width by the junction of propeller shank and hollow hub simultaneously
It is mounted with fin-shaped protrusion and extends to inside hollow hub, whens propeller works makes to flow through current near hollow hub by again
It utilizes, hydraulic pressure approaches inside and outside hollow hub, thus can effectively stop the formation in hub whirlpool.
Description of the drawings
It elaborates below in conjunction with the drawings and specific embodiments to the utility model.
Fig. 1 is the structure diagram of embodiment 1
Fig. 2 is the A-A faces partial sectional view of Fig. 1
Fig. 3 is 2 structure diagram of embodiment
Fig. 4 is the B-B faces partial sectional view of Fig. 3
Specific embodiment：
Example 1
Such as Fig. 1, shown in Fig. 2, propeller is made of fin-shaped protrusion 1, hollow hub 2, blade 3.Wherein hollow hub 2, paddle
Leaf 3 is the prior art, and in the junction of 3 root of blade and hollow hub 2, blade 3 is increased width, and to protrude from blade 3 hollow
The edge of propeller hub 2, at the same install the fin-shaped protrusion 1 with certain thickness and length by prior art screw pitch direction and blade 3 and
Hollow hub 2 is made of one and extends to inside hollow hub 2, depending on installation number is as needed.
Example 2
Such as Fig. 3, shown in Fig. 4, fin-shaped protrusion 1 and hollow hub 2 and blade 3 are Split type structure, and the side of being welded to connect can be used
Formula, remaining is the same as example 1.
