Description
Technical field
The present invention relates to a kind of propeller hub of adjustable oar propulsion system, be particularly useful for the propeller hub that to realize the feathering state of the two oar configurations of two-shipper.
Background technology
In the adjustable oar propulsion system of the two oars configurations of two-shipper at present, be that two oars move simultaneously generally speaking, but sometimes when the wall scroll oar goes wrong in real navigation needs or the underway, only have this moment an oar keeping the boats and ships operation.In the single-blade operation; Current can drive another blade running, and it is running that the rotation of blade drives whole axle, and this moment is bigger to the influence of bearing; Rotate though axle braking device can stop oar axle system, can't reduce the resistance that blade increases to hull when zero pitch state.Therefore when screw propeller is not devoted oneself to work, reduce the resistance of inoperative screw propeller as far as possible, be equivalent to reduce hull resistance, thereby make total propulsion coefficient improve.
If adopt a kind of propeller hub that can realize the feathering state; At emergency situation or when needing the low speed of a ship or plane, can stop wherein an oar and make blade be in the following current state, not only can guarantee the safety of single-blade operation; Reduce hull resistance; Energy savings, and the blade that is in the following current state can not rotatablely move at all, and blade is safer this moment.
Why can not realize the feathering state for the blade in traditional propeller hub, tracing it to its cause is: in the blade packing guide groove the position is set, in traditional propeller hub; When blade was in 0 pitch state, the guide groove line of centers was positioned at the angular bisector (see figure 1) of the adjustment angle α of blade packing, and the slide block on the saddle occupy the chute stage casing at this moment; The propeller hub of this structure; No matter be positive car operation or car backing operation, the scope of blade rotation angle all is the same, has all occupied 1/2 of α.Owing to do not allow to reach or surmount 180 ° when surmounting 180 ° (reach or be stuck easily), therefore, no matter be positive car operation or car backing operation, the angle of blade rotation all can not reach 90
0, the feathering state can not appear.At present, can realize the propeller hub of feathering state, not be seen in report.
Summary of the invention
The objective of the invention is to: be directed against the following current state that present propeller hub can't be realized blade, promptly under the single-blade running state, another oar can increase the practical problems to the hull running resistance, and a kind of new propeller hub that can realize the feathering state is provided.
The objective of the invention is to realize like this: a kind of propeller hub of realizing the feathering state; Comprise propeller hub body, blade, blade packing, saddle and the stern tube shaft that contains oil pipe; After slide block slides in guide groove the blade packing is adjusted; Maximum setting range to the blade packing is adjustment angle α, and adjustment angle α is made up of positive car zone and reversing zone, and it is characterized in that: described adjustment angle α is 110 ° ~ 130 °; Positive car zone accounts for 0.5 alpha+beta, 0.5 alpha+beta=90 °; The reversing zone accounts for 0.5 alpha-beta.
In the present invention; With the point of transition of operation of positive car and car backing operation 0 pitch state as blade, the angle that blade is in positive car zone is for just, and blade is in the regional angle of reversing and bears; The setting range of positive car operation is 0 ~ 90 °, is the feathering state when blade is in 90 °; The accent scope of car backing operation is 0 ~-(0.5 alpha-beta) °.
In the present invention, can described guide groove be located on the blade packing, described slide block is fixedly installed on the saddle outer wall, and to car backing operation direction displacement angle β, positive car zone adjustment model accounts for 0.5 alpha+beta to the line of centers of said guide groove by 0.5 α place.Or described slide block is fixedly installed on the blade packing; Described guide groove is located on the saddle outer wall; Slide block to blade packing axle center apart from the unmodified prerequisite under, with the position of slide block by 0.5 α place to car backing operation direction displacement angle β, make positive car zone account for 0.5 alpha+beta.
In the present invention, oar paddy can be adopted following structure:
A) oil cylinder is located at propeller hub body front end, and oil cylinder is connected with the propeller hub body through flange;
B) saddle places the propeller hub body, and the front portion of saddle is the ante-chamber of hollow, and the rear portion is the back cavity of hollow, and front and back are provided with dividing plate between the chamber; Form front chamber after preceding cavity outer wall inserts described oil cylinder, the front end of said stern tube shaft inserts the back cavity wall and forms rear chamber; The blade packing is located in the propeller hub body, and the blade packing simultaneously is provided with guide groove or slide block, and another side is provided with locating dowel pin; The outer wall that slide block is fixedly installed on the saddle back cavity is provided with cooresponding slide block or guide groove, and described slide block places cooresponding chute;
When c) blade and blade packing all are in 0 pitch state, locate them, and, make positive car zone account for 0.5 alpha+beta through bolt through locating dowel pin;
D) be provided with inner oil tube and outer oil pipe in the stern tube shaft, dividing plate and front chamber that inner oil tube passes in the saddle are linked up, and outer oil pipe and rear chamber are linked up, and stern tube shaft is connected with the rear end of propeller hub body through flange.
In the present invention, the cross section at described saddle rear portion is a square, and is provided with cooresponding blade packing in the cooresponding propeller hub body of four edges.
In the present invention, the outside of described oil cylinder is provided with copper sheathing.
In the present invention, before the saddle between cavity outer wall and the cylinder wall, behind the front end of stern tube shaft and the saddle between the cavity wall and be equipped with sealing arrangement between the dividing plate in inner oil tube and the saddle.
In the present invention, the shift length of saddle in oar paddy satisfies slide block omnidistance displacement in guide groove.
The invention has the advantages that: through the position that is provided with of guide groove between change blade packing and the saddle or slide block; Changed propeller hub to the distribution angle of positive car in the adjustment angle with the reversing zone; Make blade can be in the feathering state; When this propeller hub is not worked, reduced the resistance of propeller hub to ship's navigation; Because the material of oil cylinder is generally cast steel material, to prevent marine corrosion, prolong oil cylinder service life at the outside copper sheathing that increases of oil cylinder like this, reduce maintenance cost; Because saddle double as piston, the saddle front end is supported on the oil cylinder, forms front chamber between saddle front end and the oil cylinder; The front end axis body of stern tube shaft and saddle rear end inwall sliding block joint; Between stern tube shaft end face and saddle inwall, form rear chamber, structure is very compact, has increased area of thrust surface; Reduce the system pressure requirement, improved the safe reliability of system; Because outer oil pipe of the employing in the stern tube shaft and inner oil tube, the hydraulic oil in the work in the propeller hub is in recurrent state all the time, compares with single vitta structure, and the cleanliness level of hydraulic oil is higher.
