Full circle swinging adjustable pitch propelling unit
The utility model belongs to a kind of boats and ships all-direction propeller.
The tradition all-direction propeller makes screw propeller and conduit in horizontal surface, do 360 ° of rotations around vertical axis through bevel gear system transmission device, in order to the propelling boats and ships and control the direction of propulsion of boats and ships.Full-rotating rudder paddle has good handling, converts the effect that is equivalent to rudder power fully into because of it makes the thrust of its screw propeller, can play a part simultaneously to advance and handle boats and ships, can change the size and Orientation of thrust arbitrarily, can make the boats and ships pivot turn, and is free to advance or retreat.Because its complex structure, cost is higher relatively, is usually used in handling is required lower boats and ships.
Summary of the invention
For high, the handling lower deficiency of complex structure, cost that overcomes existing all-direction propeller, the utility model provides a kind of simplified structure, cost-cutting, handling good full circle swinging adjustable pitch propelling unit.
The utility model solves the technical scheme that its technical matters adopted:
A kind of full circle swinging adjustable pitch propelling unit comprises full-rotating rudder paddle axle, propeller hub and blade, and said propeller hub is installed on the full-rotating rudder paddle axle; Distance adjustor is installed in the said propeller hub; Said distance adjustor comprises the oil cylinder that is sleeved on the full-rotating rudder paddle shaft end, and said oil cylinder middle part is provided with piston, and said full-rotating rudder paddle axle is provided with the inside and outside oil pipe that is communicated with said oil cylinder both sides oil pocket respectively; Said piston is captiveed joint with saddle; Said saddle is sleeved on the said full-rotating rudder paddle axle slidably, and said saddle is provided with the slide block slot that supplies slide block to slide, and slide block is slidably mounted in the slide block slot; Said slide block is assemblied on the bent axle of crank disc, and said crank disc is installed blade.
The technical conceive of the utility model is: 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.Adjustable pitch propeller can change pitch according to the variation of boats and ships operating mode; Be rotating speed, turn under the unmodified situation at main frame and axle,, change pitch angle through the adjusting mechanism in the propeller hub; Thereby change the size and Orientation of thrust, to adapt to the advancing of boats and ships, pusher, to stop and requirement such as speed change.Blade is contained on the propeller hub with mobilizable blade fixed sturcture, drives blade by the blade rotating mechanism in the propeller hub and rotates around blade-span axis.Tuning for Controllable Pitch Propeller can not only improve the manoevreability of engine installation, and main frame need not frequently to change operating mode, and this improves reliability to prolonging the main frame life-span, reduces oil consumption, and it is all favourable to improve aspect such as economy, and easily is automated and controls.
The beneficial effect of the utility model mainly shows: simplified structure, cost-cutting, handling good.
Description of drawings
Fig. 1 is the angle of rake constructional drawing of full circle swinging adjustable pitch.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of full circle swinging adjustable pitch propelling unit comprises full-rotating rudder paddle axle 1, propeller hub 2 and blade; Said propeller hub 2 is installed on the full-rotating rudder paddle axle 1, in the said propeller hub 2 distance adjustor is installed, and said distance adjustor comprises the oil cylinder 3 that is sleeved on the full-rotating rudder paddle shaft end; Said oil cylinder 3 middle parts are provided with piston 4; Said full-rotating rudder paddle axle is provided with the inside and outside oil pipe 5 that is communicated with said oil cylinder both sides oil pocket respectively, and said piston 4 is captiveed joint with saddle 6, and said saddle 6 is sleeved on the said full-rotating rudder paddle axle 1 slidably; Said saddle 6 is provided with the slide block slot that supplies slide block to slide; Slide block 7 is slidably mounted in the slide block slot, and said slide block 7 is assemblied on the bent axle of crank disc 8, and said crank disc 8 is installed blade.
In the present embodiment, said full-rotating rudder paddle axle pastern branch also wraps drive motor, the vertical installation of said drive motor.Said adjustable pitch propeller propeller hub and blade part also comprise oil distributor and pitch feedback mechanism.During roll adjustment,, make oil cylinder internal piston both sides form difference of pressure, move forward and backward together thereby make piston on prop shaft is axial, drive saddle through the physical construction of hydraulic-driven and propeller hub component internal crank disc-saddle-slide block.Slide block on the saddle also can be done straight-line motion thereupon in slide block slot; Because slide block is assemblied on the crank of crank disc; Make the straight-line motion of slide block be converted into the circular movement of crank, finally drive crank disc and rotate, and through blade root bolt and blade root pin connecting crank dish and blade; Screw blade also can rotate around axis of runner blade thereupon, thereby changes pitch.
