【考案の詳細な説明】
本考案は、合成樹脂製のロッカカバーをシリンダヘッド
に固定する装置に関するもである。[Detailed Description of the Invention] The present invention relates to a device for fixing a synthetic resin rocker cover to a cylinder head.
周知の通り合成樹脂のロッカカバーは底形が容易で、軽
量化が可能なことから採用の傾向が高まっている。As is well known, the use of synthetic resin rocker covers is increasing because the bottom shape is easy and the weight can be reduced.
しかしその反面本格的に採用するには解決しなければな
らない問題があることも事実である。However, on the other hand, it is also true that there are problems that need to be resolved before it can be adopted on a full scale.
その問題の一つに鋳鉄製でなるシリンダヘッドへ、軟質
部材の合成樹脂製ロッカカバーをあやまって過度に締め
付けると、パツキンを必要以上に変形させたり、そのう
えロッカカバーのフランジに亀裂を生じさせるという不
具合がある。One of the problems is that if a synthetic resin rocker cover, which is a soft member, is accidentally over-tightened to a cast iron cylinder head, the packing may be deformed more than necessary, and the flange of the rocker cover may crack. There is a problem.
本考案は上記に鑑みてなされたもので、過度の締め付け
を防止し、さらにパツキンを最適な状態に圧縮させるこ
とのできる装置を提供せんとするものである。The present invention has been made in view of the above, and aims to provide a device that can prevent excessive tightening and further compress the packing to an optimal state.
以下その実施例を図面により説明する。Examples thereof will be described below with reference to the drawings.
１は合成樹脂製のロッカカバーで、周縁に形成されたフ
ランジ２には所定間隔をもってボルト孔３が設けられ、
その一方端面すなわち後述するシリンダヘッドとの対向
面には環状凹部４が形成されている。Reference numeral 1 denotes a rocker cover made of synthetic resin, and a flange 2 formed on the periphery is provided with bolt holes 3 at predetermined intervals.
An annular recess 4 is formed on one end surface thereof, that is, the surface facing a cylinder head, which will be described later.
円筒部５とつば部６が一体的に形成されたカラー７は、
つば部６を凹部４側にして円筒部５をボルト孔３へ嵌装
すると、つば部６は凹部４へ陥没して端部８と同一面を
なし、先端９とボルト孔３の開口に載置した座金１０間
にはおよそ０．ＩＷｒＩ４から０．２２ＦＥＩ１１程度
の空隙１１が形成されている。The collar 7 in which the cylindrical part 5 and the collar part 6 are integrally formed,
When the cylindrical part 5 is fitted into the bolt hole 3 with the flange 6 facing the recess 4, the flange 6 sinks into the recess 4, becomes flush with the end 8, and fits into the tip 9 and the opening of the bolt hole 3. The space between the placed washers 10 is approximately 0. A void 11 of about 0.22FEI11 is formed from IWrI4.
１２はシリンダヘッドで端面１３にはボルト１６の孔３
と対応する位置にネジ１４が設けてあり、つば部６と端
面１３間にはパツキン１５が介在されている。12 is a cylinder head, and an end face 13 has a hole 3 for a bolt 16.
A screw 14 is provided at a corresponding position, and a gasket 15 is interposed between the collar portion 6 and the end surface 13.
ロッカカバー１とシリンダヘッド１２はボルト１６の締
め付けによりパツキン１５を圧縮して液密に固定される
。The rocker cover 1 and the cylinder head 12 are fixed fluid-tightly by tightening the bolts 16 and compressing the packing 15.
円筒部５とつば部６はフランジ２の変形後の高さを規正
するもので、ボルト１６の締め付けによって僅かな空隙
１１に相当する分だけフランジ２が圧縮されると先端９
と座金１０が接触してボルト１６の締め付けが終了し、
それ以上フランジ２は変形することなく該フランジ２の
高さは規正される。The cylindrical portion 5 and the flange portion 6 regulate the height of the flange 2 after deformation, and when the flange 2 is compressed by an amount corresponding to a small gap 11 by tightening the bolt 16, the tip 9
The washer 10 comes into contact with the bolt 16, and the tightening of the bolt 16 is completed.
The height of the flange 2 is regulated without further deforming the flange 2.
そして前記のような僅かな空隙１１分だけフランジ２を
変形させるので、その圧縮荷重がパツキン１５に作用し
、つば部６で押圧されるパツキン１５は残留応力が増加
する。Since the flange 2 is deformed by the small gap 11 as described above, the compressive load acts on the packing 15, and residual stress in the packing 15 pressed by the collar 6 increases.
そため合戒樹脂製のロッカカバー１が熱によるクリープ
を起こしても、パツキン１５の反発力でボルト１６は弛
むことがない。Therefore, even if the rocker cover 1 made of synthetic resin creeps due to heat, the bolt 16 will not loosen due to the repulsive force of the packing 15.

有する。As mentioned above, the present invention is a device that fixes a synthetic resin rocker cover and a cylinder head with bolts via a gasket, in which the cylindrical part and the flange part are integrally formed and the collar is inserted into the flange. The flange is brought into contact with the packing, and a slight gap is provided between the tip of the cylindrical part and the washer placed on the flange, so that the height after flange deformation is regulated and the flange is By compressing the gasket, the bolt will not loosen due to the repulsive force of the gasket, which has an excellent effect that the liquid-tight structure will not be damaged.
