本考案はエンジンのオイルパン取付装置に関す
るものである。[Detailed Description of the Invention] The present invention relates to an oil pan mounting device for an engine.
従来のこの種のオイルパンはシリンダブロツク
に直接に取付けられてあり、シリンダブロツクか
らの励振により多大の騒音を発生していた。これ
に対して従来から遮音、制振あるいは防振の対策
が取られてきたが、コストや信頼性の問題があつ
た。 Conventional oil pans of this type are attached directly to the cylinder block, and generate a large amount of noise due to vibration from the cylinder block. Countermeasures such as sound insulation, vibration control, or vibration prevention have been taken in the past to address this problem, but these have been problematic in terms of cost and reliability.
本考案は上記の事情に鑑みなされたものであつ
て、その目的とするところは、騒音の発生が軽減
されるばかりかオイルパンが確実にシリンダブロ
ツクに取付けられて油洩れ性も向上できるエンジ
ンのオイルパン取付装置を提供することにある。 The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide an engine that not only reduces noise generation but also improves oil leakage by ensuring that the oil pan is securely attached to the cylinder block. An object of the present invention is to provide an oil pan mounting device.
以下、本考案を図面を参照して説明する。図面
中１はシリンダブロツクであり、２はオイルパン
である。オイルパン２の上部外面には周方向に所
定の間隔をおいて複数本のスタツドボルト３が植
設してある。 Hereinafter, the present invention will be explained with reference to the drawings. In the drawing, 1 is a cylinder block, and 2 is an oil pan. A plurality of stud bolts 3 are installed on the upper outer surface of the oil pan 2 at predetermined intervals in the circumferential direction.
図面中４はオイルパン２の全周に亘る防振材で
あり、この防振材４は耐油性にすぐれたNBR，
SR等が使用されている。この防振材４には横孔
５と縦孔６とが長手方向にそれぞれ所定の間隔を
おいて形成してある。 4 in the drawing is a vibration isolating material that extends around the entire circumference of the oil pan 2, and this vibration isolating material 4 is made of NBR, which has excellent oil resistance.
SR etc. are used. In this vibration isolating material 4, horizontal holes 5 and vertical holes 6 are formed at predetermined intervals in the longitudinal direction.

ロツク１に取付けてあつてスタツドボルト３及び
ボルト８により防振材４を介してシリンダブロツ
ク１にオイルパン２が取付けてある。 Then, by inserting the stud bolt 3 of the oil pan 2 into the horizontal hole 5 and tightening the nut 10, the vibration isolating material 4 is attached to the oil pan 2 via the presser plate 11 that covers the entire circumference. Circumferential presser plate 9
The bolts 8 which are brought into contact with the lower surface of the vibration isolator 4 and penetrated through the holding plate 9 are screwed into the screw holes 12 of the mounting seat 7 through the vertical holes 6, and by tightening these bolts 8, the holding plate is closed. The vibration isolating material 4 is attached to the cylinder block 1 via bolts 9, and the oil pan 2 is attached to the cylinder block 1 via the vibration isolating material 4 using stud bolts 3 and bolts 8.
しかして、シリンダブロツク１の防振力は防振
材４を介してオイルパン２に伝達されるために振
動伝達率が小さくなる。 Therefore, the vibration damping force of the cylinder block 1 is transmitted to the oil pan 2 via the vibration damping material 4, so that the vibration transmission rate becomes small.
また、防振材４の全周を押え板９，１１で押え
つけることによつて油洩れを防ぐことができる。 Further, by pressing the entire circumference of the vibration isolating material 4 with the press plates 9 and 11, oil leakage can be prevented.

材４を押えてこの防振材４を取付けたことを特徴
とするエンジンのオイルパン取付装置である。 As described in detail above, in the present invention, a plurality of stud bolts 3 are installed in the circumferential direction on the upper outer circumferential surface of the oil pan 2, and nuts 10 screwed into the stud bolts 3 are tightened around the outer circumference of the oil pan 2 to secure the entire circumference. The vibration isolating material 4 is pressed down via the holding plate 11 extending over the
This oil pan mounting device for an engine is characterized in that the vibration isolating material 4 is mounted on the cylinder block 1 by tightening bolts 8 and holding the vibration isolating material 4 through a presser plate 9 extending around the entire circumference. It is.

振材４によつて吸収されるので騒音の発生が軽減
されるばかりかオイルパン２は確実にシリンダブ
ロツク１に取付けられて油洩れ性も向上できる。 Therefore, the excitation force of the cylinder block 1 is absorbed by the vibration isolating material 4, which not only reduces the generation of noise, but also allows the oil pan 2 to be securely attached to the cylinder block 1, thereby improving oil leakage. .
