Description
Technical field:
The utility model relates to the marine propeller device, relates in particular to the improvement of boats and ships adjustable pitch propeller.
Background technology:
Adjustable pitch propeller can be rotating speed, turn under the unmodified situation because of it at main frame and axle; Rotation through propeller hub is rotated blade; Thereby change the pitch angle of blade; To change the size and Orientation of thrust, adapt to the advancing of boats and ships, retreat, stop and requirement such as speed change, thereby be widely used in the propulsion system of boats and ships.Adjustable pitch propeller can improve the manoevreability of engine installation, and main frame need not frequently to change operating mode, can make ship-machine-oar be in good matching status, improves propulsion coefficient.And be easy to realize handling automation, this improves reliability to prolonging the main frame life-span, reduces oil consumption, and it is all very favourable to improve economy.The blade of adjustable pitch propeller becomes an integral body to constitute by blade and discoid blade seat are affixed; The blade seat is fixedly mounted on the rotary propeller hub through threaded connector, in being threaded of propeller hub and blade seat, owing to have the gap between hole part and the screw rod; So the deflection angle of each blade is difficult in full accord in the actual installation; This makes adjustable pitch propeller in the working process of reality, and the thrust that each blade receives is all inequality, and this makes the stressed bigger too early damage of blade easily; Also can cause the vibration of hull; Cause hull to damage and influence the normal operation of some instrument and meter easily, also can increase the wearing and tearing of adjustable pitch propeller enclosure interior rotatable parts, reduce the service life of adjustable pitch propeller.Conforming scheme of each blade angle and measure are still rare in the raising adjustable pitch propeller at present.
The utility model content:
To the above-mentioned deficiency that prior art exists, the purpose of the utility model is that a kind of adjustable pitch propeller that detent mechanism is arranged will be provided, and it has the characteristics of blade angle high conformity, long service life, saving service expenditure.
In order to solve the problems of the technologies described above; The scheme of the utility model technical solution problem is: a kind of adjustable pitch propeller that detent mechanism is arranged; Comprise housing, blade, be installed in the rotating propeller hub in this housing and drive the transmission device that this propeller hub rotates, the side of said housing radially symmetry be processed with the propeller hub hole, the end of said propeller hub is positioned at described propeller hub hole; Described blade becomes an integral body to constitute by blade and discoid blade seat are affixed; The end face of said propeller hub is provided with screw, and described blade seat is provided with and the cooresponding through hole of said screw, also is provided with detent mechanism on described propeller hub and the described blade seat.
After adopting such scheme; Because described propeller hub and described blade seat are provided with detent mechanism; And the position of the detent mechanism on the every pair of propeller hub and the blade seat is all identical, screw in the screw on the propeller hub and with blade and be fixedly mounted on the described propeller hub so can pass through hole on the blade seat through threaded connector in the actual installation, and the location dimension of detent mechanism is all identical on every propeller hub and the blade seat; Thereby can make the deflection angle of every blade consistent; Guarantee the stressed identical of every blade in the working process, also can not increase the wearing and tearing of adjustable pitch propeller inner rotation parts, both prolonged adjustable pitch propeller service life, reduce the vibration of hull and to instrument and meter and interference; Make boats and ships be in economic good running state again, reduce expensive lying up and service expenditure.

Description of drawings:
There is the adjustable pitch propeller of detent mechanism to do further to specify below in conjunction with the accompanying drawing and the specific embodiment to the utility model.
Fig. 1 is the structural principle scheme drawing of the utility model adjustable pitch propeller that detent mechanism is arranged.
The specific embodiment:
Among Fig. 1; The adjustable pitch propeller that detent mechanism arranged by housing 1, blade, be installed in the rotating propeller hub 4 in the housing 1 and drive the transmission device that this propeller hub 4 rotates and constitute (transmission device does not draw among the figure), the side of said housing 1 radially symmetry be provided with propeller hub hole 2, the end of said propeller hub 4 is positioned at described propeller hub hole 2; Blade becomes an integral body to constitute by blade 9 and discoid blade seat 7 are affixed; Be processed with screw 5 on the end face of propeller hub 4, be processed with on the blade seat 7 and the cooresponding through hole 6 in screw 5 positions, propeller hub 4 is provided with detent mechanism with blade seat 7; Detent mechanism is the mortise structure; Be processed with a knock hole 3 on the propeller hub 4, be processed with a location lug 8 on the blade seat 7, the position of knock hole 3 and location lug 8 is corresponding each other.Earlier the location lug on the blade seat 78 is placed the knock hole 3 on the propeller hub 4 during installation; Pass in the screw 5 on the through hole 6 screw-in propeller hubs 4 on the blade seat 7 (threaded connector does not draw among the figure) with threaded connector then; Thereby blade is fixedly mounted on the propeller hub 4; Because the position of the detent mechanism on all propeller hub and the blade seat is all identical, so also unanimity of the angle of every blade is guaranteed the stressed identical of every blade in the working process; Can not increase the wearing and tearing of adjustable pitch propeller inner rotation parts yet; Both prolonged adjustable pitch propeller service life, reduce the vibration of hull and to instrument and meter and interference, make boats and ships be in economic good running state again, reduce expensive lying up and service expenditure.
