Abstract
The invention relates to a shaftless propeller which is characterized by comprising a shell (1), end covers (2), a rotating wheel (4), a propeller (5), a driving shaft (6), a driving wheel (7) and a toothed belt (8), wherein the two sides of the shell (1) are connected with the end covers (2); the rotating wheel (4) is connected between the end covers (2) by a rolling bearing (3); the rotating wheel (4) is internally and fixedly provided with the propeller (5); the shell (1) is also provided with the driving shaft (6) which is provided with the driving wheel (7); and the driving wheel (7) is connected with the rotating wheel (4) by the toothed belt (8). The propeller fixed on the rotating wheel is driven by the driving wheel arranged on the driving shaft through the toothed belt, so that the shaftless drive is realized by the shaftless propeller; and the shaftless propeller has the characteristics of being large in thrust, low in noise, free from winding, good in directionality and the like.
Description
Technical field
The present invention relates to a kind of propeller, relate in particular to a kind of nothing axle propeller, belong to ship domain.
Background technology
Since 19th-century invention propeller for watercraft propelling unit, this technology begins to use widely in ship's navigation, for very big contribution has been made in the mankind's productive force development.But along with the broad development of screw propeller technology at ship domain, its intrinsic defective also progressively manifests, should not be too high like rotating speed; Limited the speed of ship's navigation, big like noise, vibration is big; Limited the development of boats and ships again, especially noise problem has limited the use of spiral propeller on submarine; Traditional propeller all has axle in addition, twines foreign material such as pasture and water easily, and this has also hindered the navigation of boats and ships.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide that a kind of thrust is big, noise is little, do not have twine, the no axle propeller of good directionality.
The objective of the invention is to realize like this: a kind of nothing axle propeller; Comprise shell, end cap, rotor wheel, screw propeller, axle drive shaft, driving wheel and cog belt; The both sides of said shell are connected with end cap, and said rotor wheel is through being connected between the two end cap through antifriction-bearing box, and the rotor wheel internal fixation is provided with screw propeller; Also be provided with axle drive shaft on the said shell; Said axle drive shaft is provided with driving wheel, and said driving wheel and rotor wheel outer ring are equipped with the flank of tooth with the cog belt coupling, and said driving wheel is connected through cog belt with rotor wheel;
Said screw propeller comprises annulus wheel; Some lodicules evenly are fixed at the inwall of annulus wheel, and the outer rim of annulus wheel is provided with a circle flange I, and said flange I is provided with well-distributed bolt hole I; The inwall of said rotor wheel also is provided with a circle flange II; Said flange II is provided with well-distributed bolt hole II, and said bolt hole I and bolt hole II are mated each other, and said bolt hole I and bolt hole II are passed through bolted connection;
Said end cap is an annular end cap, and end cap is captiveed joint with shell through bolt;
The inboard of said two end cap is equipped with sealing member.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is fixed on the screw propeller on the rotor wheel because the driving wheel on the axle drive shaft drives through cog belt, realizes no shaft drive.
1, thrust is big, and through primary Calculation, it is than the common big 25%-30% of thrust that a screw propeller is arranged with diameter;
2, noise is little, and it does not produce bubble local behind streaming of lodicule blade tip and the leaf, thereby has basically no noise;
3, do not have winding, because its center does not have axostylus axostyle, the center is empty, can be accessible through foreign material and tank, can not produce the phenomenon that foreign material twine;
4, good directionality, screw propeller rotates in cylindrical shell, and the current rectilinear flow does not rearward have basically and distributes, and on direction, restrains, and has increased directivity and thrust;
5, if will improve speed of the ship in meters per second, can be together in series by a plurality of nothing axle propellers, form the multistage propelling unit of pressure charged, its thrust is heightened, even can reach the rank that produces the high speed shock wave, be specially adapted to military speedboat.
