Abstract
A novel distance-adjustable oar hub including an oar housing and a blade base bearing installed in the oar housing. A rotatable crank plate is installed on the outer wall of the oar housing, and a reinforcement rib is connected to the inner side surface of the oar housing. The novel distance-adjustable oar hub improves the capability for bearing seawater pressure, effectively utilizes main machine power, and prolongs the service lifetime.
Description
Technical field
The utility model belongs to the adjustable pitch propeller of boats and ships, relates in particular to a kind of tuning for Controllable Pitch Propeller propeller hub.
Background technology
Adjustable pitch propeller is made up of five big parts such as blade, propeller hub mechanism, oil distributor, hydraulic efficiency pressure system and electronic telecontrol system or system.The blade of adjustable pitch propeller is not fixed on the propeller hub; Around rotational perpendicular to the oar axle, utilize the steering unit in the propeller hub to rotate blade, change pitch angle; Thereby change the size and Orientation of thrust, advance to adapt to ship, retreat, speed change and requirement such as stop.Adjustable pitch propeller can make full use of the function and the rotating speed of main frame under different navigation operating modes, therefore be widely used in the boats and ships of each types such as towboat, auxiliary vessel, oil carrier, Scientific Research Ship.
Blade root bearing and propeller hub integral type, oil cylinder piston drives, and propeller hub links to each other with prop shaft with torsional pin with bolt originally as integral type, and blade is fastened on the crank disc through blade root screw and torsional pin, and crank-sliding block-saddle rotating vane mechanism is set in the hub; Propeller hub mechanism adopts thin oil lubricant, gravity oil oil distribution port and the axle of gravity tank through oil distributor be endoporus with the annular space of oil guide pipe formation to the propeller hub fuel feeding.
The structure of existing oar housing is thin, and it is limited in one's ability to bear sea pressure; Propeller speed is not high, causes main engine power to be not fully utilized; And influence service life of whole piece ship.
Summary of the invention
Thin for the structure that overcomes existing tuning for Controllable Pitch Propeller propeller hub, bear the deficiency that sea pressure is limited in one's ability, main engine power can not make full use of, service life is short, the novel tuning for Controllable Pitch Propeller propeller hub that the utility model provides a kind of lifting to bear the sea pressure ability, effectively utilize main engine power, increase the service life.
The utility model solves the technical scheme that its technical matters adopted:
A kind of novel tuning for Controllable Pitch Propeller propeller hub comprises oar housing and the blade root bearing that is installed in the oar housing, and the outer wall of said oar housing is installed rotating crank disc, and the medial surface of said oar housing connects reinforced rib.
Further, said crank disc has four, and four crank discs uniformly-spaced are arranged in said oar housing outer wall one circle.
Further again, first copper sheathing is installed in the said oar housing, said first copper sheathing is captiveed joint with said second copper sheathing, and said crank disc is positioned at said second copper sheathing.
The technical conceive of the utility model is: respectively add reinforced rib one from inboard four the crank disc positions of propeller hub, cast out with the oar housing.Crank disc is adorned towards the inside by oar housing outside; Solving the crank disc fixation problem is: (first copper sheathing fixes with second copper sheathing and is connected the blade root flange for one group of copper sheathing.Second copper sheathing and oar housing close-fitting are together; Make crank disc firmly and rotate and be controlled at flexibly in the oar housing; First copper sheathing is close to second copper sheathing interference fit with it, and first copper sheathing has been a transitional function, and purpose is to make blade root flange and crank disc can combine closely and rotate flexibly; And the employing copper material, also can improve the situation of serious wear between blade root flange and the crank disc.Make propeller hub can well resist the pressure of seawater under sail, make full use of main engine power, the Combination property of whole piece ship is got a promotion significantly.
The beneficial effect of the utility model mainly shows: promote the sea pressure ability of bearing, effectively utilize main engine power, increase the service life.
Description of drawings
Figure 1 is the utility model propeller pitch propeller grain structure diagram;
Fig. 2 is the structural representation of copper sheathing assembly.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2, a kind of novel tuning for Controllable Pitch Propeller propeller hub comprises oar housing 1 and the blade root bearing that is installed in the oar housing 1, and the outer wall of said oar housing 1 is installed rotating crank disc 2, and the medial surface of said oar housing 1 connects reinforced rib.
Said crank disc 2 has four, and four crank discs 2 uniformly-spaced are arranged in said oar housing 1 outer wall one circle.In the said oar housing 1 first copper sheathing 3 is installed, said first copper sheathing 3 is captiveed joint with said second copper sheathing 4, and said crank disc 2 is positioned at said second copper sheathing 4.
In the present embodiment; Through improvement to the aspects such as mounting means of oar housing structure form and crank disc; Improve new oar housing structure form and new crank disc fixed form; Make crank disc firmly and rotate and be controlled at flexibly in the oar housing, the pressure that makes ship resist seawater when the navigation through this improvement has improved, thereby also can be prolonged greatly the service life of ship.
