Problems solved by technology

[0003] However, in general, even a small marine external engine is formed to be long in the vertical direction, so it is bulky and needs to be improved in terms of portability when moving the marine external engine
In addition, for the same reason, the operation of installing a marine outboard engine to the hull is not easy
In addition, such a marine external engine also takes up a lot of space when it is stored or transported by a vehicle, which is inconvenient.

Embodiment 1

[0022] figure 1 It is a partial cross-sectional view of a marine outboard engine according to Embodiment 1 of the present invention.

[0023] exist figure 1 In , the symbol 10 represents a marine external engine. The marine outboard engine 10 passes through two stern brackets ( figure 1 Only one shown) 14 is secured to the rear (stern frame) 18 of the hull 16.

[0024] An internal combustion engine (drive source, hereinafter referred to as "engine") 20 is provided at a position above the marine outboard engine 10 in the vertical direction. The engine 20 is a single-cylinder gasoline engine with a displacement of about 50 cc, and generates an output of 1.5 kW (about 2 PS). As shown in the drawing, the crankshaft (output shaft) 22 of the engine 20 is arranged parallel to the vertical direction, and the engine 20 and the crankshaft 22 are covered by an engine cover 24 .

[0025] The so-called "up and down direction" below refers to the direction parallel (or roughly paral...

Embodiment 2

[0064] Figure 7 for with figure 1 The same partial sectional view of a marine outboard engine showing a second embodiment of the invention.

[0065] Dang Yihe figure 1 While focusing on the differences between the embodiments, in the second embodiment, a rubber mount (elastic body) 90 is arranged (assembled) inside the receiving portion 34c formed near the lower end of the motor cover 34 .

[0066] like Figure 8 to Figure 10 As shown, the rubber mount 90 is formed in a substantially cylindrical shape. The rubber mount 90 is made of an elastic material (specifically, chloroprene rubber), and its hardness (elasticity) is set to suppress transmission of the vibration of the driving source (the engine 20 and the electric motor 28) to the driving part (specifically, the driving part). Shaft cover 42) (for example, about HS60°).

[0067] This will be described below. Conventionally, a marine external engine in which an internal combustion engine or the like is mounted on a ...

Abstract

The present invention provides a marine external engine, which can improve the portability of the marine external engine, make it easy to install on a ship hull, and can reduce the space occupied during storage. A drive source [specifically, an engine (20) and an electric motor (28)] and a drive part are detachably connected by a fastening part (38), wherein the drive part has at least a drive shaft (40) and a propeller (54), the drive shaft (40) is connected with the drive source so as to be driven by it, and the propeller (54) is connected to the drive shaft (40) through the gear mechanism (44). In addition, an elastic body (90) is arranged on the fastening part (38), and the driving source part and the driving part are connected by the elastic body.

Description

technical field [0001] The invention relates to a marine outboard engine. Background technique [0002] Traditionally, smaller marine outboard engines have only been mounted to the hull (hull) by the boat operator or custodian when in use and removed from the hull when not in use And keep it in the specified storage place. Therefore, various techniques have been proposed to facilitate the operation of moving the marine outboard engine to a storage place [for example, Japanese Patent Application Laid-Open Publication No. 11-001199 (paragraphs 0019, 0026, Figure 10 Wait)]. [0003] However, generally, even a small marine external engine is formed to be long in the vertical direction, so it is bulky, and it is necessary to improve the portability when moving the marine external engine. Also, for the same reason, the operation of mounting a marine outboard engine to the hull is not easy. In addition, such a marine external engine also takes up a lot of space when it is store...
