Background art of the present invention is disclosed in Republic of Korea Utility Model Publication No. 20-0387825 (June 27, 2005, the name of the invention: the skeg of light information outboard machine).

Since the general outboard motor is disposed in the vertical direction of the engine, a separate support structure is required to rotatably support the output shaft. Therefore, it is difficult to design an outboard motor engine by applying a vehicle engine.

Therefore, there is a need for improvement.

An object of the present invention is to provide an outboard motor which can apply the output shaft mounting structure of the engine in the same way as the output shaft mounting structure of the vehicle engine.

The present invention relates to a semiconductor device comprising: a housing; An engine installed in the housing and providing power; A drive shaft through which power of the engine is transmitted; A propeller rotatably installed in the housing and rotated by the power of the engine transmitted from the drive shaft; A differential gear unit configured to shift power transmitted along the drive shaft and transmit the power to the propeller; And it characterized in that it comprises a switching unit for switching the direction in which the power of the engine is transmitted to transmit to the drive shaft.

In addition, the differential gear unit of the present invention, the differential gear unit is installed in the housing and connects the rotation shaft of the drive shaft and the propeller; And a shift shaft connected to the differential gear part and varying a speed ratio.

In addition, the output shaft of the engine is characterized in that it is disposed in the horizontal direction orthogonal to the drive shaft.

In addition, the switching unit, the main gear is installed on the output shaft; And a driven gear connected to the main gear and connected to the drive shaft.

The outboard motor according to the present invention can be equipped with the output shaft of the outboard motor engine in the same way as the output shaft mounting structure of the vehicle engine, so that the outboard motor engine can be manufactured by applying the engine for the vehicle, which can reduce the time and cost required for the outboard motor development. There is an advantage.

1 is a diagram illustrating an outboard unit according to an embodiment of the present invention.

Hereinafter, an embodiment of an outboard motor according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation.

In addition, the terms described below are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

Referring to FIG. 1, an outboard motor according to an embodiment of the present invention includes a housing 1, an engine 10 installed in the housing 1 to provide power, and a drive through which power of the engine 10 is transmitted. The propeller 80 is rotatably installed in the shaft 50, the housing 1, and rotated by the power of the engine 10 transmitted from the drive shaft 50, and is transmitted along the drive shaft 50. It includes a differential gear unit 70 for shifting the power to the propeller 80, and the switching unit 30 for changing the direction in which the power of the engine 10 is transmitted to the drive shaft 50.

When the engine 10 is driven after the housing 1 is installed at the rear of the boat, the power of the engine 10 is transmitted along the drive shaft 50, and the power is reduced or increased while passing through the differential gear part 70. This propeller 80 is delivered.

Therefore, since the propeller 80 located below the water surface rotates to generate a propulsion force, the boat moves forward or backward.

The switching unit 30 transfers the driving direction of the power of the engine 10 and transmits it to the drive shaft 50, so that the drive shaft 50 is disposed long in the vertical direction even when the mounting position of the engine 10 varies. It is possible to transmit the power of the engine 10 to.

In the engine 10 of the present embodiment, the output shaft 12 is disposed in the horizontal direction, and is connected by the drive shaft 50 and the switching unit 30 arranged in the vertical direction.

The output shaft 12 of the engine 10 is disposed in the horizontal direction to be orthogonal to the drive shaft 50.

Since the output shaft 12 of the engine 10 according to the present embodiment has a similar mounting structure to the output shaft of the vehicle engine disposed in the horizontal direction, the engine 10 of the outboard motor can be developed by applying the vehicle engine.

The differential gear unit 70 is connected to the differential gear unit 70 and the differential gear unit 70 which is installed in the housing 1 and connects the rotation shaft of the drive shaft 50 and the propeller 80, and the transmission ratio is variable. And a shift shaft 52.

The differential gear unit 70 has a structure similar to that of the differential gear installed in the power transmission unit of the vehicle, and the differential gear unit is driven according to whether the shift shaft 52 connected to any one of the pair of differential gears is driven. The power passing through the fisherman 70 is decelerated or increased.

Here, the connection structure and the operation relationship between the differential gear portion 70 and the shift shaft 52 can be easily implemented by those skilled in the art with the technical configuration of the present invention will not be described in detail or description.

A plurality of piston shafts 14 rotatably connected to the output shaft 12 and rotating the output shaft 12 are arranged at intervals in the horizontal direction.

A plurality of pistons are installed in the engine 10, and a piston shaft 14 connected to the piston is rotatably installed on the output shaft 12.

Therefore, power is generated while the linear motion of the piston shaft 14 generated by repeated explosion of fuel is converted into the rotational motion of the output shaft 12.

Since the piston shaft 14 of the present embodiment is spaced in the horizontal direction and the plurality of piston shafts 14 are disposed, the load applied to the plurality of piston shafts 14 is equally applied.

Therefore, compared with the plurality of piston shafts 14 arranged in the vertical direction, the problem of designing by calculating gravity or load is reduced.

The switching unit 30 includes a main gear 32 installed on the output shaft 12 and a driven gear 34 geared to the main gear 32 and connected to the drive shaft 50.

Since the main gear 32 and the driven gear 34 is connected in a bevel gear method, the power of the engine 10 transmitted in the horizontal direction is converted into a vertical direction and transmitted to the drive shaft 50.

Therefore, an engine in which the output shaft is disposed in the horizontal direction, such as a vehicle engine, can be used as the outboard motor engine 10.

Since the main gear 32 and the driven gear 34 are disposed inside the covers 16 and 16 installed between the engine 10 and the housing 1, the connection portions of the main gear 32 and the driven gear 34. Prevent foreign matter from entering.

Looking at the operation of the outboard motor according to an embodiment of the present invention configured as described above are as follows.

After the housing 1 is installed at the rear of the boat, the lower end of the housing 1 is placed below the surface of the water, and the engine 10 is driven so that the power of the engine 10 passes through the piston shaft 14 to the output shaft 12. It is transmitted to the main gear 32 along.

At this time, the direction in which the power of the engine 10 proceeds is switched from the horizontal direction to the vertical direction.

Thereafter, the power of the engine 10 is transmitted to the drive shaft 50 through the driven gear 34 geared to the main gear 32.

The power of the engine 10 transmitted along the drive shaft 50 is converted to the horizontal direction again while passing through the differential gear portion 70 and transmitted to the rotation shaft of the propeller 80.

Therefore, the propeller 80 disposed below the water surface is rotated to provide propulsion to the boat.

As a result, it is possible to provide an outboard unit which can apply the output shaft 12 mounting structure of the engine 10 in the same manner as the output shaft 12 mounting structure of the vehicle engine 10.
