Description
Technical field
The utility model relates to a kind of adjustable pitch screw propeller peculiar to vessel, belongs to equipment of Vessel field.
Background technology
Screw propeller is to depend on blade to rotate in air or water, turn of engine power is converted into the device of propulsive force, can have two or more leaf to be connected with hub, and the one side backward of leaf is for helical surface or be similar to a kind of ship propeller of helical surface; Yet what nowadays on boats and ships, use is all generally fixed pitch propeller, and the diesel main engine of employing spacing oar, its minimum speed of a ship or plane is subject to the restriction (being generally 6 ~ 7 joints) of diesel engine minimum steady speed, if boats and ships are navigated by water with Ultra-Low Speed, just must make main frame start intermittently, stop, once and dead stick, will lose steerage, affect manoeuvre of ship, when large ship passes through complicated navigation channel or inward & outward, conventionally need Ultra-Low Speed navigation, and existing screw propeller can not navigate by water by Ultra-Low Speed, so this is a urgent problem.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable pitch screw propeller peculiar to vessel.
Problem to be solved in the utility model be existing screw propeller can not Ultra-Low Speed the defect of navigation.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of adjustable pitch screw propeller peculiar to vessel of the utility model, comprise blade, bolt a, bolt b, tailing axle, protective cover, propeller hub, blade flange, streamlined reefer housing, bearing dish, pull bar, movable block, chute and eccentric pin, blade has three, be welded on respectively on blade flange, bearing dish is contained on propeller hub, blade flange is arranged on propeller hub by bolt a, propeller hub head is provided with streamlined reefer housing, propeller hub rear portion is provided with protective cover, tailing axle is fixed together by bolt b and propeller hub, tailing axle is hollow structure, pull bar is through tailing axle, movable block has three, be separately fixed on pull bar, on each movable block, be provided with a horizontal chute, relative with bearing dish respectively, bearing dish bottom is provided with an eccentric pin, and eccentric pin is contained in chute.
The threaded portion of bolt a and bolt b scribbles molybdenum disulphide, and scribbles sealant at its planar section.
The utility model has the advantages that: the effect by pull bar is moved movable block, thereby eccentric pin is moved in chute, the eccentric action of eccentric pin on bearing dish, makes the translation straight-line motion of pull bar change rotatablely moving of blade into, realizes the object that blade pitch changes; Therefore improved the maneuvering performance of boats and ships, can in the situation that main frame does not stop, realize Ultra-Low Speed navigation arbitrarily, and can also make where necessary oar alternately with positive car or reversing work, guarantee steerage.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of a kind of adjustable pitch screw propeller peculiar to vessel of the utility model;
Fig. 2 is the partial cutaway diagram of a kind of adjustable pitch screw propeller peculiar to vessel of the utility model;
In figure: 1, blade 2, bolt a 3, bolt b 4, tailing axle 5, protective cover 6, propeller hub 7, blade flange 8, streamlined reefer housing 9, bearing dish 10, pull bar 11, movable block 12, chute 13, eccentric pin.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
A kind of adjustable pitch screw propeller peculiar to vessel of the utility model, comprise blade 1, bolt a2, bolt b3, tailing axle 4, protective cover 5, propeller hub 6, blade flange 7, streamlined reefer housing 8, bearing dish 9, pull bar 10, movable block 11, chute 12 and eccentric pin 13, blade 1 has three, be welded on respectively on blade flange 7, bearing dish 9 is contained on propeller hub 6, and bearing dish 9 rotates at the interior energy of propeller hub 6; Blade flange 7 is arranged on propeller hub 6 by bolt a2, and propeller hub 6 heads are provided with streamlined reefer housing 8, and streamlined reefer housing 8 plays the effect of water conservancy diversion, reduces the resistance of water; Propeller hub 6 rear portions are provided with protective cover 5, and protective cover 5 plays a protective role, and seawater can not be entered in propeller hub 6; Tailing axle 4 is fixed together by bolt b3 and propeller hub 6, and tailing axle 4 drives whole screw propeller to rotate, and tailing axle 4 is hollow structure, pull bar 10 is through tailing axle 4, and pull bar 10 can be in the interior movement of tailing axle 4, and and then tailing axle 4 synchronously rotates, movable block 11 has three, is separately fixed on pull bar 10; On each movable block 11, be provided with a horizontal chute 12, relative with bearing dish 9 respectively, bearing dish 9 bottoms are provided with an eccentric pin 13, eccentric pin 13 is contained in chute 12, under the effect of eccentric pin 13 and chute 12, can make the translation straight-line motion of movable block 11 change rotatablely moving of bearing dish 9 into.
The threaded portion of bolt a2 and bolt b3 scribbles molybdenum disulphide, and scribbles sealant at its planar section.
The utility model using method, first whole propeller is arranged on boats and ships, pull bar 10 is moved by hydraulic power, by pull bar 10, drive the movable block 11 being fixed on pull bar 10, eccentric action due to bearing dish 9 bottom eccentric pins 13, thereby change the translation straight-line motion of pull bar 10 into blade 1 rotatablely move, therefore realize the object that blade 1 pitch changes; By variable pitch oar, can realize from zero to the infinite speed variation maximum speed, and in the situation that main frame does not stop also without commutation, can realize down boat at an easy rate; Can in the situation that main frame does not stop, realize Ultra-Low Speed navigation arbitrarily, and can also make where necessary oar alternately with positive car or reversing work, guarantee steerage.
