Description

[Detailed Description of the Invention] The present invention relates to an improvement of a common anti-vibration support device for a marine internal combustion engine and an auxiliary machine. Originally, ships required auxiliary equipment such as generators, hydraulic pumps, and miscellaneous water pumps, and these were conventionally installed in the engine room with vibration isolators separate from the main engine's vibration isolators. .

However, as mentioned above, installing auxiliary equipment in the engine room through a vibration isolator inevitably increases the size of the equipment, and the disadvantage is that the auxiliary equipment cannot fit into the engine room on ships that do not have engine room space, such as small fishing boats. Furthermore, even if the engine room is entered, the vibration isolating device for attaching the auxiliary equipment is complicated, difficult to install, and the vibration isolating device is also expensive.

Therefore, the purpose of this invention is to solve the above-mentioned drawbacks and to provide an excellent common vibration isolation between the engine and auxiliary equipment of a marine internal combustion engine, which allows the auxiliary equipment to be installed in the engine room without increasing the space of the engine room. A support device is provided.

The marine internal combustion engine of the present invention that achieves the above objectives is:
A vibration isolator is provided on the top of the left and right engine stands, an L-shaped auxiliary equipment mounting plate is interposed between the vibration isolator and the engine, the auxiliary equipment is mounted on the side of the plate, and the auxiliary equipment is attached to the belt. It is characterized by a common anti-vibration support device for the engine and auxiliary equipment of a marine internal combustion engine that is driven.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a main marine engine 1 equipped with auxiliary equipment, which is an embodiment of the present invention. In this example, the vibration isolator 3 of the present invention is placed between the left support leg 1a and the engine stand 2 when viewed from the front of the main engine 1.
is supported, and an auxiliary machine 4 is attached to this vibration isolator 3.

This auxiliary machine 4 is a generator in this embodiment, and its pulley 4a is connected to the front power take-off pulley 1b of the main engine 1 by a V-belt 5, so that it is driven by the belt from the main engine side. .

In Fig. 1, 1c is a gear case, and 1d is an oil pan.

FIG. 2 is an enlarged partial view showing the essential parts of the vibration isolator 3 of the present invention shown in FIG. 1, and FIG. 3 is a view taken along arrow A in FIG.

In this example, an upper plate 8 is attached to the upper part of a lower plate 5 fixed to the engine stand 2 via a rubber vibration isolating member 7.

A stud bolt 9 is provided protruding from this upper plate 8,
An L-shaped auxiliary equipment mounting plate 11 is attached to the upper plate 8 along with main engine installation bolts 10.

In this embodiment, this L-shaped auxiliary equipment mounting plate 11 is formed to have an L-shaped cross section, and is designed to allow auxiliary equipment (not shown) to be mounted horizontally into the mounting hole 11a with bolts or the like. Its shape is not limited to the shape of this embodiment, and the shape can be changed depending on the auxiliary equipment.

With this configuration, even when the auxiliary equipment installed around the marine internal combustion engine is driven by a belt from the main engine side as shown in Fig. Since it is supported by a vibration device, there is almost no loosening of the V-belt 5, and the V-belt 5 is
The belt 5 also does not easily come off, and the auxiliary equipment operates smoothly.

As explained above, the present invention uses the vibration isolating device interposed between the engine stand and the main marine engine in common with the vibration isolating device for the auxiliary machinery, so that the auxiliary machinery can be moved without increasing the space in the engine room. Since it can be installed, it has the effect that auxiliary machinery with a vibration isolator can be supplied at low cost even to ships such as small fishing boats where the engine room does not have a large space.

Furthermore, even when the auxiliary equipment is driven by a belt from the main engine side as mentioned above, the auxiliary equipment is supported by the same vibration isolator as the main engine, so there is almost no chance of the belt loosening or coming off, and there is no possibility of auxiliary equipment failure. It has the effect of being small.

In addition, on the vibration isolator common to the engine and auxiliary equipment,
Since a letter-shaped auxiliary equipment mounting plate is provided and the auxiliary equipment is mounted on the side, it is possible to install the auxiliary equipment on either the left or the right depending on the engine installation and space. It is convenient that the L-shaped auxiliary equipment mounting plate can be selectively mounted on either the left or right side.
