Generally, small-sized boats are equipped with an outboard engine, which is a small size engine, mainly on the outside of the hull, and the propulsion power of about 2 horsepower to about 350 horsepower is obtained.

However, the fuel used for the outboard engine is excessively consumed and the output is small. Therefore, it can not be used for a large-sized yacht or a large boat, and a gasoline or diesel engine mounted inside the hull is used as a main power source And an inboard engine system in which the power generated by the engine is transmitted to a stern drive installed outside the hull to obtain propulsion.

However, since the engine for generating power is located inside the hull, there is a merit of not touching the sea water. However, due to the structural characteristics of the hull, the propulsion device and the propeller are always positioned below the sea surface Not only the service life of the parts is shortened but also foreign materials such as seaweeds and barnacles are adhered to cause frequent breakdown of the propulsion device and thereby the life of the engine is drastically reduced.

In addition, even if a rope or a foreign object is wrapped around a propeller, even if it is attempted to repair it, it is far from the stern so that it is not easy for a person to work, and there is a problem that time, cost and manpower are excessively consumed.

Furthermore, there is a risk of safety accidents such as an engine being overheated or damaged or a fire being generated due to a foreign matter being attached to a propulsion device, a propeller, etc., so that cooling water to be supplied to the engine can not be supplied smoothly.

There is the same problem such as corrosion of one part and adhesion of foreign matter.

Also, since the sliding length of a certain distance is required to lift the propulsion device, the size of the gearbox becomes large, and there is a safety risk due to the sliding tolerance length.

As shown in FIGS. 5 to 9, the present invention is characterized by a power transmission body that transmits power from an engine inside a hull to a propulsion device outside the hull, and smoothly performs steering, steering, and tilting. One side of the flywheel plate 10 is completely fixedly coupled to one side of an engine (not shown) to transmit the rotational power of the flywheel plate 10.

The other side of the flywheel 10, which is not coupled to the engine, has a "T" shaped cross section with a central portion protruding therefrom and is connected to a rotational power along the rotational axis of the engine.

The protruded central portion of the flywheel plate 10 is preferably formed in a hollow cylindrical shape, and the spline flange 20 is fitted to an empty central portion.

The protrusion of the spline flange 20 may be formed on the inner circumferential surface of the flywheel plate 10 so as to have a concave / convex shape bent in a direction perpendicular to the rotation direction of the engine. The flywheel plate 10 and the spline flange 20 can be fitted and engaged with each other and the high rotational force of the engine can be transmitted to the propulsion device.

A first nut flange 30 is fixedly coupled to one side surface of the spline flange 20 by bolts. One end of the reinforcing coil 50 is coupled to the first nut flange 30, The second nut flange 60 having the same structure as that of the first nut flange 30 is coupled to the other end of the second nut flange 50.

The ship propulsion device using the reinforced coil power transmission of the present invention is particularly characterized in the shape and the joining method of the reinforced coil 50 connecting the engine and the propulsion device. It is wound in a counterclockwise direction (left-hand direction) instead of a clockwise direction (right-hand screw direction).

10 and 11 showing the reinforcing coil 50, it can be seen that the direction of rotation of the reinforcing coil 50 is formed while rotating in the counterclockwise direction, To prevent breakage of the reinforcing coil (50) and to prevent loosening of the coupling.

The reinforcing coil 50 includes a connecting coil 52 formed at both ends connected to the first nut flange 30 and the second nut flange 60 and a tilting coil 51 formed at the center Since the connecting coil 52 is tightly coupled to the first nut flange 30 and the second nut flange 60 to transmit and support the rotational force of the engine, the connecting coil 52 is relatively in contact with the tilting coil 51 It is preferable to further tightly wind it.

10 and 11, it can be seen that the spacing distance between the connecting coils 52 is smaller than the spacing distance between the tilting coils 51. The reinforcing coil 50, Thereby increasing the bonding force and the supporting force.

The tilting coil 51 is freely rotatable or bendable due to a wider spacing so that it can flex freely in all directions corresponding to an arbitrary pressure externally applied, As shown in Fig.

12 and 13 illustrate a first nut flange 30 and a second nut flange 60 for use in a ship propulsion system using a reinforced coil power transmission according to the present invention. The first nut flange 30, And the second nut flange (60) have a flat disc-like engaging portion (31); An extension part 32 formed to extend in one direction from the coupling part 31 and formed into a hollow cylindrical shape; A center protrusion 33 protruding from the engaging portion 31 so as to be equal to a direction in which the extending portion 32 is formed at the center of the extending portion 32; And the like.

The first nut flange 30 and the second nut flange 60 have the same shape and are connected to the spline flange 20 located on the engine side or the pinion spline 70 positioned on the propeller side Only whether or not they are coupled is different.

The coupling portion 31 is fixedly coupled to the spline flange 20 or the pinion spline 70 by bolt coupling so that the direction of the reinforcing coil 50 from the coupling portion 31, (32) protruding in a direction facing each other between the first nut flange (30) and the second nut flange (60).

The extension portion 32 may be formed in a hollow cylindrical shape, and thus a space through which the reinforcing coil 50 can be engaged is provided.

A center protrusion 33 is formed in the center of the extended portion 32. The center protrusion 33 is disposed concentrically with the extended portion 32 to divide the inner space of the extended portion 32 Thereby forming a fitting space 34 into which the reinforcing coil 50 can be fixedly coupled.

For this coupling, the inner circumferential surface of the extended portion 32 and the outer circumferential surface of the central protrusion 33 are respectively threaded to allow the connection coil 52 of the reinforcing coil 50 to rotate and be coupled, Since the reinforcing coil 50 in the counterclockwise direction (left-handed direction) is used, the inner circumferential surface of the extended portion 32 and the outer circumferential surface of the center protrusion 33 are also formed in the counterclockwise direction .

The outer circumferential surface of the connecting coil 52 and the inner circumferential surface of the extending portion 32 may be connected to each other to secure the connection between the connecting coil 52 and the first nut flange 30 and the second nut flange 60. [ And the inner periphery of the connecting coil 52 and the outer periphery of the central projection 33 coincide with each other.

The connecting coil 52 is inserted into the fitting space 34 by forming a thread of the extending portion 32 and the central projection 33 so that the connecting coil 52 is completely equal to the interval and the number of rotations, It is possible to firmly fix it by simply rotating coupling, and it is possible to smoothly transmit the power even when the engine rotation of several thousand rpm is not released.
