Description
【０００１】[0001]
本考案は、防振ブッシュの改良に関する。 The present invention relates to an improvement of an anti-vibration bush.
【０００２】[0002]
公知の防振ブッシュは、内環の外周側に弾性体を介して外環を接続し、弾性体 をゴム状弾性材により環状に成形している。 In a known vibration-proof bush, an outer ring is connected to an outer peripheral side of an inner ring via an elastic body, and the elastic body is formed into an annular shape by a rubber-like elastic material.
【０００３】[0003]
従来の防振ブッシュにおいては、負荷が径方向に入力した場合には、弾性体が 圧縮で使用されて剛性が大きいために該負荷が大きくてもこれに耐えることがで きるが、負荷が軸方向または捩り方向（円周方向）に入力した場合には、弾性体 が剪断で使用されて剛性が小さいために該負荷が大きいとこれに耐えることがで きず、弾性体が破損する虞がある。 In the conventional anti-vibration bush, when a load is input in the radial direction, the elastic body is used for compression and has a large rigidity, so even if the load is large, it can withstand this. When inputting in the direction or the twisting direction (circumferential direction), the elastic body is used by shearing and has low rigidity, so if the load is large, it cannot withstand this, and the elastic body may be damaged. .
【０００４】[0004]
本考案は以上の点に鑑み、上記従来技術にみられる問題を解消し、防振ブッシ ュの耐久性を向上することを目的として考案されたものであって、この目的を達 成するため、内環の外周側に弾性体を介して外環を接続した防振ブッシュにおい て、前記内環の外周面にはす状の突起を設け、前記外環の内周面にはす状の凹み を設け、前記突起と前記凹みを前記弾性体を介して軸方向および捩り方向に係合 したことを特徴とする防振ブッシュを提供する。 In view of the above points, the present invention was devised with the object of solving the problems found in the above-mentioned conventional techniques and improving the durability of the vibration-proof bushing.To achieve this object, In an anti-vibration bush in which the outer ring is connected to the outer peripheral side of the inner ring via an elastic body, a protrusion is provided on the outer peripheral surface of the inner ring, and a concave recess is formed on the inner peripheral surface of the outer ring. Is provided, and the projection and the recess are engaged with each other in the axial direction and the torsional direction through the elastic body.
【０００５】[0005]
内環の外周面にはす状の突起を設け、外環の内周面にはす状の凹みを設け、こ の突起と凹みを弾性体を介して軸方向および捩り方向に係合すると、負荷が軸方 向または捩り方向に入力した場合に、弾性体のうち突起と凹みに挾まれた部分が 圧縮で使用されることになって剛性が大きくなる。 A protrusion is provided on the outer peripheral surface of the inner ring, and a recess is formed on the inner peripheral surface of the outer ring.When the protrusion and the recess are engaged with each other in the axial direction and the torsional direction through an elastic body, When the load is input in the axial direction or the torsional direction, the part of the elastic body sandwiched between the protrusion and the recess is used for compression and the rigidity is increased.
【０００６】[0006]
つぎに本考案の実施例を図面にしたがって説明する。 Next, an embodiment of the present invention will be described with reference to the drawings.
【０００７】 図１は本考案の実施例に係る防振ブッシュの正面図と側面図である。内環１の 外周面に所要数（図では四本）のはす状の突起２が等配に形成され、外環３の内 周面に所要数（図では四本）のはす状の凹み４が等配に形成され、この突起２と 凹み４が一本ずつ組をなして、弾性体５を介して軸方向および捩り方向に係合し ている。突起２および凹み４はそれぞれ内環１または外環３の軸方向一端から他 端まで達するように形成されている。「はす状」は「ねじ状」または「螺旋状」 である。 しかして上記構成の防振ブッシュによれば、軸方向または捩り方向の負荷が入 力して内環１と外環３が同方向に相対に変位した場合に、弾性体５のうち突起２ と凹み４に挾まれた部分が圧縮で使用されて大きな剛性を有しているために、該 負荷が大きくてもこれに耐えることが可能である。また軸方向の負荷と捩り方向 の負荷が同時に入力した場合にも、弾性体５の一部が圧縮で使用されるために当 該防振ブッシュの耐久性を向上させることができる。 尚、外環３は、図２に示すように、その外周面に歯車（はす歯歯車等）の歯６ を形成したものであっても良い。FIG. 1 is a front view and a side view of an anti-vibration bush according to an embodiment of the present invention. The required number (4 in the figure) of the projections 2 of the shape of a lotus are formed on the outer peripheral surface of the inner ring 1 in an equal arrangement, and the required number (4 in the figure) of the bean-shaped protrusions 2 are formed on the inner surface of the outer ring 3. The recesses 4 are formed at equal intervals, and the projections 2 and the recesses 4 are paired one by one and engaged with each other in the axial direction and the twisting direction via the elastic body 5. The protrusion 2 and the recess 4 are formed so as to reach from one end in the axial direction of the inner ring 1 or the outer ring 3 to the other end. "Lotus shape" is "screw shape" or "spiral shape". However, according to the vibration-proof bush having the above-described structure, when the axial load or the torsional load is applied and the inner ring 1 and the outer ring 3 are relatively displaced in the same direction, the protrusions 2 Since the portion sandwiched in the recess 4 is used for compression and has a large rigidity, it is possible to withstand even a large load. Further, even when a load in the axial direction and a load in the torsional direction are simultaneously input, a part of the elastic body 5 is used for compression, so that the durability of the vibration isolation bush can be improved. The outer ring 3 may have teeth 6 of a gear (a helical gear or the like) formed on its outer peripheral surface, as shown in FIG.
【０００８】[0008]
本考案は次の効果を奏する。すなわち、軸方向または捩り方向の負荷が入力し て内環と外環が相対に変位した場合に、弾性体のうち突起と凹みに挾まれた部分 が圧縮で使用されて大きな剛性を有しているために、該負荷が大きくてもこれに 耐えることができる。また軸方向の負荷と捩り方向の負荷が同時に入力した場合 にも、当該防振ブッシュの耐久性を向上させることができる。 The present invention has the following effects. That is, when an axial or torsional load is input and the inner ring and the outer ring are displaced relative to each other, the portion of the elastic body that is sandwiched between the protrusion and the recess is used for compression and has great rigidity. Therefore, even if the load is large, it can withstand this. Further, even when the axial load and the torsional load are simultaneously input, the durability of the vibration isolation bush can be improved.
