Description of the Related Art For example, when a head cover or an oil pan is attached to a cylinder head or a cylinder block of an engine, in order to prevent noise and damage due to vibration transmission, these are supported by a vibration-proof rubber or spring for vibration-proof support. Is well known.

ている。Reference numeral 1 denotes a vibrating body serving as a vibration source, and 2 denotes an object to be insulated, which are connected by a bolt 5 via a distance 3 and a vibration-proof rubber 4 fitted to the outer periphery thereof. 6 is a gasket or rubber packing. The distance 3 is made of iron, and the pipe portion 7 into which the bolt 5 is inserted and the pipe portion 7
And a seat surface portion 8 that is integrally formed at the upper end of and extends radially outward. The anti-vibration rubber 4 has substantially the same shape as the distance 3, and its ring-shaped support portion 9 is sandwiched between the lower surface of the seat surface portion 8 and the upper surface of the flange 10 of the insulator 2 to absorb or insulate vibration. Further, the anti-vibration rubber 4 has a tubular portion 11 that fits over the entire outer circumference of the tube portion 7 of the distance 3, and the tubular portion 11 is in close contact with the entire outer peripheral surface of the tubular portion 7 to prevent coming off from the distance 3. However, the assembling is improved. Further, the tubular portion 11 is also fitted in the mounting hole 10a formed in the flange 10 to thereby perform the vibration isolation of the object to be insulated 2 in the horizontal direction and, at the same time, the positioning thereof in the horizontal direction.
【0005】このように、ディスタンス形の利点とし

れる。As described above, the advantage of the distance type is that the antivibration rubber 4 can be mounted on the distance 3 in advance, so that the assembling property is good, and the antivibration rubber 4 can be appropriately compressed and supported, so that the optimal vibration absorption and durability are obtained. Can be maintained.

【発明が解決しようとする課題】ところで、図9に示す
ように、防振ゴム4の支持部9は、それが軸即ち厚さ方
向に潰れ変形を行うことにより、座面部8とフランジ1
0との間をシールする役割も果たしている。By the way, as shown in FIG. 9, the supporting portion 9 of the vibration-proof rubber 4 is crushed and deformed in the axial direction, that is, in the thickness direction, so that the bearing surface portion 8 and the flange 1 are formed.
It also plays the role of sealing the gap between 0 and 0.
【0007】支持部9は変形前9aに対し9bのように

い。The support portion 9 is deformed like 9b with respect to the pre-deformation portion 9a, but the outer peripheral edge portion 12 of the support portion 9 can be easily deformed because it is escaped radially outward. On the other hand, the inner peripheral edge portion 13
Is restricted by the tube portion 7 of the distance 3 and cannot be deformed inward in the radial direction. In other words, the point 12a of the outer peripheral edge portion 12 can be largely displaced radially outward to the point 12b, that is, the rubber can flow, while the point 1a of the inner peripheral edge portion 13 can be moved.
3a can make only a small axial displacement to point 13b.
【0008】そのため、変形が規制される分、内周縁部

周縁部13近くにへたり限界値qを越える部分aがある
ため、長期間使用すると劣化によりこの部分aの内部応
力が減少し、平均応力値が下がってシール性が悪化する
問題が生じる。Therefore, a relatively large internal stress remains in the vicinity of the inner peripheral edge portion 13 due to the restriction of the deformation. That is,
As shown in FIG. 10, the internal stress distribution is biased near the inner peripheral edge portion 13. In the case of a new product, a predetermined average stress p, that is, a sufficient sealing surface pressure can be secured even in this state, but there is a portion a near the inner peripheral edge portion 13 or exceeding the limit value q. Internal stress decreases, the average stress value decreases, and the sealing property deteriorates.

いものの方が望ましく、この観点からも上記のものは、
内周縁部13の変形の規制により振動絶縁機能を低下さ
せていた。On the other hand, regarding vibration absorption, it is preferable to use a soft material which facilitates rubber flow in which internal stress gradually increases with respect to displacement.
The vibration insulation function is lowered due to the restriction of the deformation of the inner peripheral edge portion 13.

たものは従来報告例が見当たらない。As a countermeasure against this, the inner peripheral edge portion 1 of the anti-vibration rubber 4 is
It is conceivable that a clearance is provided between the distance 3 and the tube portion 7 of the distance 3, and the clearance allows deformation inward in the radial direction to obtain a uniform and sufficient internal stress. A conventional anti-vibration support structure using such anti-vibration rubber is, for example,
Examples include those disclosed in Japanese Patent Publication 57-58710 and Japanese Utility Model Publication No. 60-26257. Regarding the former, the anti-vibration rubber is not the above-mentioned distance type one, but the bolt is directly inserted therein, and the ones that function similarly to the supporting portion 9 and the tubular portion 11 are individually provided. However, if this is done, the workability of mounting the anti-vibration rubber is poor, and there is a risk that it will fall off during the mounting, and there is a problem that the assemblability deteriorates. In addition, the number of parts increases, resulting in high cost. On the other hand, with regard to the latter, this is also not a distance type, so that the assemblability is poor, and there is no component that functions in the same manner as the above-mentioned tubular portion 11, and vibration isolation and positioning in the lateral direction cannot be performed. Thus, when considering a distance type vibration proof rubber, there is no conventional report that has all of the advantages and functions.

In a vibration-damping support structure including a distance that is integrally formed at one end of the portion and that extends outward in the radial direction thereof, and a vibration-proof rubber that is fitted to the distance, the vibration-proof rubber is A ring-shaped support portion fitted to the outer periphery of the pipe portion and arranged along the seat surface portion, a gap portion formed along the inner peripheral edge portion of the support portion, and a gap portion filled to fill the gap portion with the outer periphery of the pipe portion. It comprises a plurality of circumferentially extending drop-off portions extending integrally along the axial direction.

る。By virtue of the fact that the drop-off portion presses the outer circumference of the distance tube portion, the anti-vibration rubber can be attached to the distance in advance and the assemblability can be improved. Further, the clearance allows the inner peripheral edge of the support to deform radially inward, whereby sufficient vibration absorption, durability, and sealability can be obtained.

And the surface portion 8. The vibration-proof rubber 4 fitted to the distance 3 has a ring-shaped support portion 9 fitted to the outer periphery of the pipe portion 7 and arranged along the lower surface of the seat surface portion 8. The support portion 9 is formed in a tapered shape in which the lower portion is slightly narrowed in the ring cross section, and the inner peripheral edge portion 13 thereof has a groove-shaped gap portion 14 formed along it. Gap 14
Has a groove shape with an open bottom end and an upward depth,
A tubular thin portion 16 and, in particular, three stopper portions 17 provided at equal intervals in the circumferential direction are integrally formed on the radially inner side. The thin portion 16 partitions and forms a radially inner side wall forming the gap portion 14 and a peripheral wall of the center hole 15 of the support portion 9. It also serves as a stiffener connecting the three drop-off portions 17. The hole diameter of the center hole 15 before being fitted to the distance 3 is slightly smaller than the outer diameter of the tube portion 7 of the distance 3. Therefore, the center hole 15 is slightly expanded and deformed at the time of fitting. As shown in FIG. 2, the drop-off portion 17 is formed in a substantially semi-circular shape in cross section, fills the gap portion 14, and extends integrally along the outer peripheral wall of the pipe portion 7 in the axial direction. The diameter of the circle that is in contact with the outer end, that is, the apex of the semicircle is made slightly larger than the diameter of a mounting hole 10a (see FIG. 5) of the object to be insulated 2 described later.

図られている。FIG. 5 is a diagram showing a state in which the insulator 2 is attached to the vibrating body 1 using the distance 3 and the vibration-proof rubber 4. The vibrating body 1 is provided with a bolt hole 18, and the flange 10 of the object to be insulated 2 is provided with a mounting hole 10a. A gasket or rubber packing 6 is provided between the mounting surfaces of the vibrating body 1 and the insulator 2. Mounting hole 10
"a" is aligned with the bolt hole 18, and the anti-vibration rubber 4 to which the distance 3 is previously attached is inserted into the mounting hole 10a. At this time, the retaining portion 17 is pushed between the peripheral wall of the mounting hole 10a and the peripheral wall of the tube portion 7 of the distance 3. Further, the bolt 5 is inserted from above into the pipe portion 7 of the distance 3, and the bolt 5 is fixed in the bolt hole 18. It should be noted that the bolts 5 are standard or standardized products to reduce the cost.

できる。As shown in FIGS. 1 to 3, when the anti-vibration rubber 4 is fitted into the distance 3, the thin portion 16 of the anti-vibration rubber 4 is inserted.
The locking portion 17 presses the outer peripheral surface of the tube portion 7 of the distance 3, and the friction between them prevents the vibration isolating rubber 4 from falling off, which can improve the mounting workability and the assembling property. Also, after a long period of time, the elastic force of the thin portion 16 having a small thickness, that is, the pressing force may decrease due to the deterioration of the rubber, but the retaining portion 17 still retains sufficient elastic force. For example, it is possible to prevent loss even when attaching and detaching for maintenance.

巾に高めることができる。Further, as shown in FIG. 5, after the mounting, the supporting portion 9 of the vibration isolating rubber 4 is crushed and deformed in the axial direction. Then, the inner peripheral edge portion 13 of the support portion 9 is deformed radially inward so as to fill the gap portion 14. Further, the outer peripheral edge portion 12 is deformed so as to escape outward in the radial direction as described above. As a result, uniform deformation is possible from the inner peripheral edge portion 13 to the outer peripheral edge portion 12. As shown in FIG. 6 and FIG. 7, the internal stress distribution of the support portion 9 is not biased in the radial direction at the time of new installation, that is, immediately after installation, and the maximum stress value does not sag and does not exceed the limit value q and its vicinity. Is a uniform distribution. Therefore, the average stress p can be maintained at a sufficient value even after a long period of time, and high sealability and durability can be secured. Further, since there is no hard portion having a high internal stress, the vibration can be softly absorbed, and thus the vibration absorption can be greatly enhanced.

Is inserted. As a result, the flange 10, that is, the object to be insulated 2 can be laterally vibration-proofed and simultaneously positioned. Especially, since the drop-off portions 17 are provided only at three positions at equal intervals in the circumferential direction, the vibration-proof support and positioning can be performed with the minimum number if necessary, and the gap portion 14 is provided between them.
There is an advantage that a place for providing the can be secured. Further, the thin-walled portion 16 that bridges them prevents bending and deformation during insertion and facilitates assembly.
