Description

【０００１】
【発明の属する技術分野】
本発明は、エンジンの支持装置に関する。より詳しくは、エンジンの支持位置や配置上の自由度が向上するエンジンの支持装置に関する。
【０００２】
【従来の技術】
従来のエンジンの支持装置においては、エンジンケースに取付部を形成し、この取付部を介してエンジンを機体に固定する技術が公知となっている（例えば、特許文献１参照）。例えば、船舶用のエンジン支持装置において、図１０に示すように、エンジン１００のケース１０１と取付部１０２・１０２とを一体的に構成するとともに、該取付部１０２・１０２をケース１０１から左右方向に向けて突出して配設していた。そして、該取付部１０２・１０２を据付脚１０３・１０３にボルト等の固定手段で固定し、該据付脚１０３・１０３を機体の固定部１０４・１０４に取付部材１０５・１０５を介して固定していた。このような構成で、機体の固定部１０４・１０４にエンジン１００を載置固定し、エンジン１００を支持していた。また、エンジンの振動が機体に伝達されるのを防止するため、エンジンの機体に対する相対移動を防止する移動防止手段を使用し、振動の伝達を阻止していた。従来は、この移動防止手段を適宜位置に設けていた。例えば、特許文献１の図２に示すように、移動防止手段を適宜長さのパイプサポートで構成する。そして、移動防止手段のパイプサポートを圧縮される方向の脚部間に設置し、エンジンの機体に対する相対移動を防止するとともに、エンジンの振動を機体に伝達するのを防いでいた。

【発明が解決しようとする課題】
しかし、従来のエンジンの支持装置において、エンジンケースに形成されている取付部は、エンジンケースの左右側方に突出した状態に形成されているため、取付幅が広く、また、取付高さが高くなるという不具合があった。
【０００５】
従って、エンジン取付時のエンジンの重心が高くなり、また、取付幅が広くなることで、エンジンの共振回転数が上がる。このエンジンの共振を防止するため、アイドリング回転数を上げていたが、アイドリング回転数を上げることによって、騒音、振動の問題や燃費が悪いという問題が生じていた。
【０００６】
また、エンジンの振動が機体に伝達されるのを防止する移動防止手段は、広い取付スペースが必要であり、また、移動防止手段の支持方法は片持ち支持構造となっていたので、強度不足、過大な荷重が発生するなどの問題があった。そこで、本発明では、エンジンの支持位置や配置上の自由度が向上するエンジンの支持構造を提供する。
【０００７】
【課題を解決するための手段】
本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。

エンジン（１）を据付けるエンジン支持部材であって、動力取出用伝動ケース（１１）と別体に形成した据付部材（２０）を介して、エンジン（１）を支持し、該据付部材（２０）は、本体部（２１）、取付部（２３・２３）で構成し、該本体部（２１）はプレート状に構成され、略中央部に嵌入孔（２１ａ）を設け、該嵌入孔（２１ａ）には、該動力取出用伝動ケース（１１）の外周を嵌入できる形状とし、前記取付部（２３・２３）は、該据付部材（２０）の左右側端部にプレート状に形成して配設し、側面上下方向に複数箇所の固定孔（２３ａ）を設け、該固定孔（２３ａ）に対して、据付脚（３１）の取付高さを調節し、エンジン（１）の取付位置の調節を可能とし、該据付脚（３１）は、正面視Ｌ字状のプレートで、垂直部（３２）と水平部（３３）とで構成し、該垂直部（３２）にも孔が形成されており、前記取付部（２３・２３）の固定孔（２３ａ）と固定し、該水平部（３３）には、取付孔（３３ａ）を形成し防振支持部（４０）を接続可能とし、該据付脚（３１）に防振支持部ストッパ（３６）を設け、該防振支持部ストッパ（３６）は、正面視において据付脚（３１）の前記垂直部（３２）と水平部（３３）の角部に設け、該据付脚（３１）の内面沿った状態でＬ字状に形成し、該防振支持部ストッパ（３６）を、側面視で据付脚（３１）より後方に突出配置し、該据付脚３１の後面角部を覆うように構成したものである。
【０００９】
【発明の実施の形態】
次に、発明の実施の形態を説明する。
【００１０】
図１は本発明に係るエンジン支持装置を装備したエンジンの全体側面図、図２は同じく全体正面図である。
【００１１】
図３は据付部材の正面図、図４は同じく側面図、図５は取付部の側面図、図６はストッパが装着された据付脚を示す平面図である。
【００１２】
図７は同じく側面図、図８は同じく正面図、図９は別実施例の据付部材の正面図、図１０は従来のエンジン支持構造を示す正面図である。
【００１３】
まず、図１、図２よりエンジンの全体構成から説明する。エンジン（内燃機関）１は複数のピストンを収納したシリンダとクランクケースからなるシリンダブロック２にクランク軸３が軸支され、該クランク軸３の一端（本実施例では後端）は減速ギヤケース６に挿入されて、該ギヤケース６より出力軸（図示せず）が突出される。
【００１４】
前記シリンダブロック２下部がオイルパン４により覆われ、該オイルパン４内に潤滑油が貯留されている。また、前記シリンダブロック２の上部はシリンダヘッド５により覆われ、その上方に弁腕室８が配置され、該弁腕室８の上に更に過給機９が配置され、該弁腕室８の一端に熱交換器（クーラー）１０が配置されている。
【００１５】
そして、前記シリンダブロック２の一側（本実施例では前側）に、動力取出用伝動ケースであるギヤケース１１を付設して、カムギヤやポンプ駆動ギヤ等を収納している。該ギヤケース１１には据付部材２０が装着されており、前記エンジン１は本体側に設けられている固定台１９・１９に該据付部材２０を介して支持されている。また、エンジン１の後部に設けられている前記ギヤケース６にも据付部材を装着し、エンジン１の後部を支持している。
【００１６】
次に、据付部材２０について説明する。据付部材２０は、エンジン１を支持するためのものであり、図３、図４に示すように、本体部２１、補強メンバ２２・２２、取付部２３・２３等で構成されている。前記本体部２１は、プレート状に構成され、本実施例では、正面視八角形に形成されており、左右幅は、左右の固定台１９・１９（図２）間の距離より若干小さく形成されている。該本体部２１の略中央部には、嵌入孔２１ａが設けられており、該嵌入孔２１ａは前記ギヤケース１１の外周を嵌入できる形状としている。また、本体部２１には、据付部材２０をエンジン１に装着固定する際に使用する、固定用の孔２１ｂ・・・が前後方向に穿設され、ボルト等の固定手段で装着できるようにしている。
【００１７】
前記補強メンバ２２・２２は、据付部材２０をエンジン１に装着した時に、クランク軸３の中心の上下に位置する部分に設けられている（図２）。本実施例では、補強メンバ２２・２２は、本体部２１の上部・下部の二箇所に配設されている。本体部２１の上部に設けられている補強メンバ２２は、左右両端が低く中央部が高く形成されており、左右両端は、左右の取付部２３・２３の上部に接続している。一方、本体部２１の下部に設けられている補強メンバ２２は、上部に設けられた補強メンバ２２と上下方向に対称に形成されており、左右の取付部２３・２３の下部に接続している。よって、上下の補強メンバ２２・２２は、前記嵌入孔２１ａを囲むように配置している。また、補強メンバ２２・２２は、前記本体部２１の一側面（本実施例では前面）から突出して形成され、本体部２１と一体的に構成されている。このように、据付部材２０の、クランク軸３中心上下に位置する部分に、補強メンバ２２・２２を設けることで、据付部材２０の剛性を効率的に向上することができ、据付部材２０の軽量化を図ることができる。
【００１８】
前記取付部２３・２３は、据付部材２０の左右側端部に配設されている。該取付部２３・２３は、プレート状に形成されており、図５に示すように、側面に固定孔２３ａ・・・が設けられている。前記固定孔２３ａ・・・は、前後方向に二列、上下方向に数箇所（本実施例では三箇所）配設されている。該固定孔２３ａ・・・を上下方向に数箇所設けることで、後述する据付脚３１・３１の取付高さを調節でき、よって、エンジン１の取付位置の調節が行なえる構成としている。従って、エンジン１の配置構成に応じてエンジン１の位置の調節が行なえ、エンジン特性に応じたエンジン１の配置を行なえ、振動や騒音を低減することができる。
【００１９】
そして、図３、図４に示すように、前記取付部２３・２３には据付脚３１・３１が固定されている。該据付脚３１・３１は、正面視Ｌ字状のプレートで、垂直部３２・３２と水平部３３・３３とで構成されている。また、据付脚３１・３１の角部の前面と後面に補強部材３４・３４を設け、据付脚３１・３１の補強を行なっている。前記据付脚３１の垂直部３２は、左右方向に孔が形成されており、前記取付部２３の固定孔２３ａ・・・と固定手段であるボルト２９・・・等で固定されている。また、前記据付脚３１の水平部３３には、中央部にボルトを嵌入する取付孔３３ａが形成されており、後述する防振支持部４０を接続できるようにしている。
【００２０】
次に、防振支持部４０について説明する。防振支持部４０は、載置台４１、カバー４２、防振部材４３、取付プレート４４、ネジ部材４５、高さ調節部材４６等で構成されている。前記載置台４１は、前記固定台１９（図２）に載置され、固定手段２８等で固定台１９に固定されている。該載置台４１の上面には、防振部材４３を覆うカバー４２が立設しており、該カバー４２内部に防振部材４３を填充している。そして、前記防振部材４３の上方に取付プレート４４が固定されている。前記取付プレート４４には、ネジ部材４５が取付けられている。該ネジ部材４５は、取付プレート４４の上面の略中央部から上方に立設しており、溶接等により取付プレート４４と一体的に構成している。そして、前記ネジ部材４５に、高さ調節部材４６が装着されている。高さ調節部材４６は、前記据付部材２０の装着時の高さを調節するもので、本実施例の高さ調節部材４６は、二個のナット４６ａ・４６ａを使用している。該ナット４６ａ・４６ａは、前記ネジ部材４５に嵌入され、設定高さに該ナット４６ａ・４６ａを調節固定している。
【００２１】
このような構成の防振支持部４０に、前記据付部材２０を装着したエンジン１を固定する。まず、エンジン１と前記据付部材２０の取付から説明する。図２、図３に示すように、該エンジン１の前部に設けられているギヤケース１１に、前記据付部材２０の嵌入孔２１ａを挿入する。そして、前記本体部２１に設けられている固定用の孔２１ｂ・・にボルト等を嵌入し、ギヤケース１１と据付部材２０とを固定する。また、据付部材２０の左右側部に設けられている取付部２３・２３に、前記据付脚３１・３１を取付ける。該据付脚３１・３１は、据付部材２０の設定高さに合わせて選択される固定孔２３ａ・・を使用して、ボルト２９・・・により取付部２３・２３に締結固定される。次に、前記据付部材２０及び据付脚３１・３１を装着したエンジン１と、防振支持部４０との取付について説明する。前記防振支持部４０のネジ部材４５に、上方から該据付脚３１の取付孔３３ａを嵌入する。該据付脚３１は、前記高さ調節部材４６の上方に載置固定され、更にネジ部材４５にナット４７を嵌入し、締結して、防振支持部４０に据付部材を接続して、エンジン１を支持している。
【００２２】
このように、動力取出用伝動ケースであるギヤケース１１と別体に形成した据付部材２０を介してエンジン１を支持するので、エンジン１の支持幅の減少等、エンジン１支持位置の自由度が向上する。また、エンジン１に接続した据付部材２０の側部に据付脚３１・３１を取付け、該据付脚３１・３１を介してエンジン１を支持するので、エンジン１の配置構成に応じて、据付脚３１・３１が選択可能であり、エンジン１の配置上の自由度が向上する。更に、据付部材２０に防振支持部４０を接続してエンジン１を支持することで、エンジン１の振動による変位を効率的に防振支持部４０に伝達し、振動を効率的に吸収することができる。
【００２３】
次に、防振支持部ストッパ３６について説明する。防振支持部ストッパ３６は、前記据付部材２０側部に設けた据付脚３１に設けられている。図６乃至図８に示すように、防振支持部ストッパ３６は、正面視において据付脚３１の角部に設けられており、据付脚３１の内面沿った状態でＬ字状に形成されている。また、防振支持部ストッパ３６は、側面視で、据付脚３１より後方に突出しており、据付脚３１の後面角部を覆うように構成している。該防振支持部ストッパ３６は、据付脚３１に溶接等により一体的に構成されている。なお、防振支持部ストッパ３６と据付脚３１とを一体成形とすることもできる。このような構成とすることで、防振支持部ストッパ３６は、機体のスラスト方向、ローリング方向、ピッチング方向の揺れに対応することができるので、ストッパに過大な力がかからないため、ストッパの耐久性を向上させ、据付性を向上させることができる。また、据付脚３１に防振支持部ストッパ３６を設けるので、防振支持部ストッパ３６を含む防振支持構成をコンパクトに構成できる。また、該防振支持部ストッパは、据付部材２０自体に取付けることもできる。
【００２４】
次に、据付部材の別実施例について説明する。図９に示すように、据付部材５０は、本体部５１、補強メンバ５２、プレート５３・５３、支持部５４等から構成されている。本体部５１はプレート状に構成されている。また、本体部５１の一面から、補強メンバ５２及び支持部５４が突出して形成されており、該補強メンバ５２及び支持部５４と、本体部５１は、一体的に構成している。また、本体部５１の左右両端には、プレート５３・５３が突出しており、本体部５１と一体的に構成されている。前記補強メンバ５２は、本体部５１の上部に設けられている。そして、補強メンバ５２は、左右両端が低く中央部が高く形成されており、左右両端はプレート５３・５３の上端に接続している。その他の構成は、前記据付部材２０と同様の構成としている。
【００２５】
一方、本体部５１の下部には、支持部５４が設けられている。支持部５４は、本体部５１の一面から突出して配設されており、本体部５１と一体的に構成されている。該支持部５４は、左右両端が高く、中央部を低く形成しており、水平部５４ａと、傾斜支持部である傾斜部５４ｂ・５４ｂとから構成されている。左右の傾斜部５４ｂ・５４ｂは、水平部より厚く構成しており、該傾斜部部５４ｂ・５４ｂに対して垂直方向に取付孔５４ｃ・５４ｃが形成されている。そして、前記取付孔５４ｃ・５４ｃに防振支持部６０を嵌入し、据付部材５０を固定している。該防振支持部６０は、斜め内側にむけて立設しており、前述の防振支持部４０と略同様の構成としている。このような構成で、防振支持部６０の高さ調節部材６６により据付部材５０の支持高さを調節し、ネジ部材６５に前記取付孔５３ｃを嵌入して、ナット６７で締結し、据付部材５０を防振支持部６０に接続している。このように、エンジン１に接続する据付部材５０に、傾斜支持部である傾斜部５４ｂ・５４ｂを設けることをで、容易な構成により、ローリング方向の振動を低減することができる。
【００２６】
【発明の効果】
本発明は、以上のように構成したので、以下に示すような効果を奏する。
【００２７】

BACKGROUND OF THE INVENTION
The present invention relates to an engine support device. More specifically, the present invention relates to an engine support device that improves the engine support position and the degree of freedom in arrangement.
[0002]
[Prior art]
In a conventional engine support device, a technique for forming an attachment portion on an engine case and fixing the engine to the airframe via the attachment portion is known (for example, see Patent Document 1). For example, in a marine engine support device, as shown in FIG. 10, the case 101 and the mounting portions 102, 102 of the engine 100 are integrally formed, and the mounting portions 102, 102 are arranged in the left-right direction from the case 101. It was arranged to protrude. The mounting portions 102 and 102 are fixed to the mounting legs 103 and 103 by fixing means such as bolts, and the mounting legs 103 and 103 are fixed to the fixing portions 104 and 104 of the airframe via mounting members 105 and 105. It was. With such a configuration, the engine 100 is mounted and fixed on the fixing portions 104 and 104 of the airframe to support the engine 100. Further, in order to prevent the vibration of the engine from being transmitted to the airframe, a movement preventing means for preventing a relative movement of the engine with respect to the airframe is used to prevent the vibration from being transmitted. Conventionally, this movement preventing means has been provided at an appropriate position. For example, as shown in FIG. 2 of Patent Document 1, the movement preventing means is configured with a pipe support having an appropriate length. And the pipe support of the movement preventing means is installed between the legs in the direction to be compressed to prevent relative movement of the engine with respect to the airframe and to prevent the vibration of the engine from being transmitted to the airframe.

Japanese Patent Laid-Open No. 7-215295
[Problems to be solved by the invention]
However, in the conventional engine support device, the mounting portion formed on the engine case is formed so as to protrude to the left and right sides of the engine case, so that the mounting width is wide and the mounting height is high. There was a problem of becoming.
[0005]
Accordingly, the center of gravity of the engine when the engine is mounted is increased and the mounting width is increased, so that the engine rotational speed is increased. In order to prevent the resonance of the engine, the idling speed has been increased. However, raising the idling speed has caused problems such as noise and vibration and poor fuel consumption.
[0006]
Moreover, the movement preventing means for preventing the vibration of the engine from being transmitted to the airframe requires a wide mounting space, and the support method for the movement preventing means has a cantilevered support structure, so that the strength is insufficient. There were problems such as excessive load. Therefore, the present invention provides an engine support structure that improves the engine support position and the degree of freedom in arrangement.
