Description
Technical field
The utility model relates to propeller for vessels, especially relates to ship shaft and carries the multistage counter rotating propeller of conduit.
Background technology
Screw propeller is simple with its structure, the more high advantage of technology maturation, conversion efficiency, it is still the main propulsion mode of current modern army-ship for civil use at present, and the research and development application of counter rotating propeller in sequential propeller sequential, then successfully solve monomer screw propeller to postpone eddy energy in wake flow and cannot utilize, become restriction propulsion coefficient and be difficult to improve this pendent difficult problem for a long time.To turn oar due to former and later two screw propeller hand of rotation on horizon contrary, but water flow rotary direction is consistent, but effectively can absorb the eddy energy in bow oar wake flow, therefore can improve marine engine widely and advance conversion efficiency.
At present boats and ships counter rotating propeller mainly contains three kinds of different structural shapes in the world: be respectively the concentric shaft type researched and developed by Japan to turning oar (CRP), the DuaT-EndCRP propulsion system released by STEERPROP company and bavin electricity mixing pod propulsion (CRP) propulsion system released by ABB AB of Britain.These are several to turning the application of paddle type formula through recent two decades, although conversion efficiency is improved, but in real-world operation, all there is following drawback: complex structure, when installing and using this propulsion system, after former propeller system need be removed, the equipment of new increase again, this will bring a large amount of maintenance loads to follow-up operation, particularly it will destroy the hull structure of new shipment, this brings new potential safety hazard by vessel motion, complicated structure occupies hull finite space, high cost, the power input newly increased, simultaneously can't with the interconnected compatibility of existing ship propeller propulsion system, therefore technological value is caused to be difficult to promote.
Utility model content
For the drawback in above-mentioned existing technology existing for counter rotating propeller, the utility model provides that a kind of structure is simple, volume compact, it not destroy under hull structure just can with the interconnected compatibility of existing almost various ships screw propeller (first wife made full use of by transforming ship puts propeller propulsion system), the ship shaft that just significantly can improve conversion efficiency carries the multistage counter rotating propeller of conduit.Particularly because this axle carries turning the structure institute of oar extremely, it also has concurrently and effectively solves boats and ships half immersion screw propeller while guarantee significantly improves propulsion of ship efficiency, because oar dish blade face half is in water, half is in atmosphere exposed, the difficult problem that the water noise that shake oar phenomenon serious when causing running and effectively reducing produces in military, civilian ship's navigation progradation is excessive.
The technical scheme that the technical problems to be solved in the utility model is taked is, described ship shaft carry the multistage counter rotating propeller of conduit comprise the axle be connected with hull carry conduit and be disposed on axle carry in conduit be connected with each other to turning device, describedly comprise casing to turning device, be contained in the rotating forward helicallobe of front axle one end and be contained in the reversion helicallobe of rear axle one end, described front axle one end is by power driven, the front axle other end to be movably arranged on bearing and rotating forward crowngear is housed, the other end of rear axle to be movably arranged on bearing and reversion crowngear is housed, front axle is connected with the solid axle sleeve of rear axle, sun gear shaft is provided with between solid axle sleeve and casing, be symmetrically arranged with turning gear up and down at sun gear shaft, be meshed respectively with rotating forward crowngear and the crowngear that reverses to turning gear, described casing is fixed on axle by strut bar and carries on conduit, tank ends end cap and sealing layer by bearing felt in casing.
The utility model can realize reaching to transhipment is dynamic the object significantly improving propulsion coefficient by coaxially multistage on the same axle of same power driven with two (or multiple to turning device), thus realizes multistage counter rotating propeller work.
The utility model is not only simple and compact for structure but also can be compatible with various ships propeller propulsion system quickly and easily, only need carry out transformation and upgrade to propeller for vessels simply, under not destroying hull structure, not increasing ship power input condition, just can realize that counter rotating propeller is efficient, the oar rudder integration work of low noise and convenient, flexible operation.
