Description

Quiet propeller

Technical field

This utility model relates to submarine propulsion device, a kind of quiet propeller.

Background technology

The still nuclear-powered submarine that China's submarine is either conventional at present, is all dependent on screw propeller, and it is excessive that screw propeller stirs water noise, is easily found by sonar.

Utility model content

For solving problem present in background technology, the utility model proposes and a kind of stir the underwater sound sound quiet propeller of little submarine.

Technical scheme: a kind of quiet propeller promoting navigation of submarine, including driving shaft, bevel gear, driven axle, spur gear, paddle arm groove, gear cover, base plate, support, described quiet propeller is in the left and right sides of spur gear, it is each provided with a paddle arm groove, the outside of its groove is open type, and inner side is half open type；One paddle arm is set in groove, buting iron, live axle, rectangular blade and opening it is provided with outside it, inner side is provided with tooth bar, it is provided with bevel gear on described driving shaft, bevel gear is engaged another bevel gear, another bevel gear connects electromotor driven axle, and the periphery of bevel gear, spur gear is provided with gear cover.

Provide the benefit that: by using the technical solution of the utility model, noise during navigation can be substantially reduced, thus reduce the probability found by sonar.

Accompanying drawing explanation

Fig. 1 is quiet propeller side view.

Fig. 2 is quiet propeller top view.

Fig. 3 is the top view that quiet propeller increases blade.

In figure, 1, submarine rear end, 2, driving shaft, 3, bevel gear, 4, bevel gear, 5, driven axle, 6, spur gear, 7, paddle arm groove, 8, gear cover, 9, base plate, 10, support, 11, paddle arm, 12, buting iron, 13, blade, 14, live axle, 15, opening, 16, tooth bar.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described further.

By a kind of quiet propeller promoting navigation of submarine shown in Fig. 1, Fig. 2, Fig. 3, including driving shaft, bevel gear, driven axle, spur gear, paddle arm groove, gear cover, base plate, support, described quiet propeller is in the left and right sides of spur gear, it is each provided with a paddle arm groove, the outside of its groove is open type, and inner side is half open type；One paddle arm is set in groove, buting iron, live axle, rectangular blade and opening it is provided with outside it, inner side is provided with tooth bar, it is provided with bevel gear on described driving shaft, bevel gear is engaged another bevel gear, another bevel gear connects electromotor driven axle, and the periphery of bevel gear, spur gear is provided with gear cover.

Concrete, this utility model eliminates propeller, lengthen driving shaft length, change the rotating manner of axle, first then rotate counterclockwise clockwise, alternation, combined by the bevel gear on driving shaft, connect driven axle, , spur gear, realize the transmission of power and 90 ° turn to, and gear cover, support, base plates etc. are auxiliary equipment, when gear rotates toward the clockwise direction, drive the paddle arm in right arm groove while launching blade, advance backward on one side, simultaneously, paddle arm in the arm groove of left side is while drawing blade in, forward end is put back on one side, when spur gear rotates counterclockwise, paddle arm in the arm groove of the left and right sides, blade alternating movement round about.
