Abstract
A feathering propeller hub structure applied to ship propulsion mainly comprises a propeller hub body, a guide frame, a blade base, a blade, a propeller shaft, an external oil pipe, an internal oil pipe and a slide block, wherein the guide frame is positioned in the propeller hub body and divides the propeller hub body into a right oil chamber and a left oil chamber; hydraulic oil are filled in the two oil chambers through the external oil pipe and the internal oil pipe; a groove is formed under the blade base; the slide block is arranged in the groove; eccentric pins are arranged on the guide frame; the guide frame, the eccentric pins, the slide block and the blade base constitute a slider crank mechanism; the blade is in the aheading position when the directions of the eccentric pins are perpendicular to a propeller axis; and the blade driven by the eccentric pins can rotate to a position where the surface of the blade is parallel to the propeller axis nearly. The feathering propeller hub structure has the characteristics of compact structure, reliable strength, high safety and the like, and is applicable to multiple different operating conditions; the resistance of an out-of-service propeller can be reduced greatly; and the total propulsion efficiency can be improved, thereby achieving the purposes of energy saving, consumption reduction and efficient ship propulsion.
Description
Technical field
What the present invention relates to is a kind of feathering propeller hub structure that is applied to propulsion of ship, is particularly useful for frequent coming and going, and tune space finite sum has a plurality of angle of rake boats and ships, like double end ferry boat, two oar oil tanker, boat and passenger boat.
Background technology
More existing large ships and special purpose boats and ships; The a plurality of propellers of general employing, and these screw propellers all are conventional adjustable oar usually, when the part screw propeller is out-of-run; If can reduce the resistance of this part screw propeller, just can improve the efficient of total propelling.And conventional adjustable oar is not worked, when promptly blade pitch is zero, this moment blade and axis normal; The resistance that screw propeller receives is maximum; If can the position of blade be transferred to and parallel axes, at this moment resistance will reduce greatly, but existing conventional propeller hub structure can't satisfy above-mentioned need of work.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, and a kind of compact conformation is provided, intensity is reliable; Safe; Go for multiple different operating mode, significantly reduce the not resistance of working screw oar, improve total efficient that advances; Can be energy-saving and cost-reducing, efficiently advance the feathering propeller hub structure that is applied to propulsion of ship of boats and ships.
The objective of the invention is to accomplish through following technical scheme; It mainly comprises propeller hub body, saddle, blade seat, blade, oar axle, outer oil pipe, inner oil tube and slide block; Described saddle be positioned at the propeller hub body and the propeller hub body is divided into about two oil pockets; These two oil pockets feed hydraulic oil through outer oil pipe and inner oil tube respectively, and described blade seat below has groove, and slide block places groove; Saddle is provided with eccentric pin; Said saddle, eccentric pin, slide block and blade seat have been formed slider-crank mechanism, and said eccentric pin direction of living in is the positive car position of blade when vertical with propeller axis, and the blade that drives through eccentric pin can turn to the blade face position almost parallel with propeller axis.
Described blade is bolted on the blade seat through blade, and blade drives through the built-in Fu of propeller hub body and rotates, and oar axle and blind flange are fixed on the propeller hub body through bolt with flange together.
The four sides of said saddle is provided with eccentric pin, and described inner oil tube is communicated with the left oil pocket of propeller hub body, and outer oil pipe is communicated with the right oil pocket of propeller hub body.
Owing to the adjustable oar that the stroke of feathering is conventional relatively is much bigger, general structure is easy to take place locking phenomenon; And the present invention is arranged on saddle with eccentric pin but not on the blade seat, the bigger oil pressure thrust arm of force is arranged like this, can not reduce to produce locking phenomenon owing to the arm of force, makes total more reliable.Blind flange, oar axle get up through same bolted connection, have reduced the length of propeller hub, and structure is more compact.
The present invention has compact conformation, and intensity is reliable, characteristics such as safety height, and it goes for multiple different operating mode, significantly reduces the not resistance of working screw oar, improves total efficient that advances, thereby reaches energy-saving and cost-reducing, efficiently advances the purpose of boats and ships.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Label among the figure is: 1 propeller hub body, 2 saddles, 3 blade seats, 4 blades, 5 slide blocks, 6 blade bolts, 7 blind flanges, 8 bolt with flanges, 9 oar axles, 10 outer oil pipes, 11 inner oil tubes.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description.Shown in Figure 1; The present invention mainly comprises propeller hub body 1, saddle 2, blade seat 3, blade 4, oar axle 9, outer oil pipe 10, inner oil tube 11 and slide block 5; Described saddle 2 be positioned at propeller hub body 1 and propeller hub body 1 is divided into about two oil pockets; These two oil pockets feed hydraulic oil through outer oil pipe 10 and inner oil tube 11 respectively, and described blade seat 3 belows have groove, and slide block 5 places groove; Saddle 2 is provided with eccentric pin; Said saddle 2, eccentric pin, slide block 5 and blade seat 3 have been formed slider-crank mechanism, and said eccentric pin direction of living in is the positive car position of blade when vertical with propeller axis, and the blade 4 that drives through eccentric pin can turn to the blade face position almost parallel with propeller axis.
The four sides of said saddle 2 is provided with eccentric pin, and described inner oil tube 11 is communicated with the left oil pocket of propeller hub body, and outer oil pipe 10 is communicated with the right oil pocket of propeller hub body.
Working process of the present invention is:
A) when passing through inner oil tube 11, hydraulic oil gets into left oil pocket; Saddle 2 begins to move to right; Hydraulic oil in the right oil pocket begins to return, and saddle 2 moves to right and drives slide block 5 and move to right, and slide block 5 drives 3 rotations of blade seat through the trough of blade seat 3 bottoms; Blade seat 3 is fixing through blade bolt 6 with blade 4, thereby makes blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized the feathering of boats and ships, and positive car stops or reversing.
B) when passing through outer oil pipe 10, hydraulic oil gets into right oil pocket; Saddle 2 begins to move to left; The hydraulic oil of a left side in the oil pocket begins to return, and saddle 2 moves to left and drives slide block 5 and move to left, and slide block 5 drives 3 rotations of blade seat through the trough of blade seat 3 bottoms; Blade seat 3 is fixing through blade bolt 6 with blade 4, thereby makes blade 4 rotate to set angle.Blade 4 rotates the purpose that has reached roll adjustment, has realized reversing, parking, positive car or the feathering of boats and ships.
