本考案は、ダンパの改良に関する。本考案のダンパは自動車エンジン等の各種 の回転駆動系に装着され、クランクシャフト等の回転シャフトに生起される振動 を吸収減衰するトーショナルダンパとして用いられる。 The present invention relates to an improved damper. The damper of the present invention is attached to various rotary drive systems such as an automobile engine, and is used as a torsional damper that absorbs and dampens vibrations generated in a rotary shaft such as a crankshaft.
【０００２】[0002]
従来から、図６および図７に示すように、円筒部２の軸方向一端に内周方向へ 向けてフランジ３を設けたスリーブ１を有し、ハブ４の外周側に円筒部２を嵌着 し、フランジ３の軸方向一方であってハブ４側に弾性体５を介して質量体６を接 続したダンパが知られている。このダンパは製造時、各部品を図示した状態に組 み立ててからスプレー装置等を使用して塗装されるものであり、特にスリーブ１ は板金製であって、塗装しないと大気に晒されて錆びてしまう。 Conventionally, as shown in FIGS. 6 and 7, a sleeve 1 having a flange 3 is provided at one axial end of a cylindrical portion 2 toward the inner peripheral direction, and the cylindrical portion 2 is fitted to the outer peripheral side of a hub 4. However, there is known a damper in which the mass body 6 is connected to the hub 4 side on one side of the flange 3 in the axial direction via the elastic body 5. At the time of manufacture, this damper is assembled by assembling the parts as shown in the figure and then painted using a sprayer, etc. Especially, the sleeve 1 is made of sheet metal and if it is not painted, it will be exposed to the atmosphere. It will rust.
【０００３】[0003]
上記ダンパにおいて、スリーブ１には、円筒部２の内周面およびフランジ３の ハブ４側の軸方向端面に、ハブ４に接触していない、または弾性体５に覆われて いない表面露出部分７がある。そしてこの表面露出部分７は各部材に囲まれてい て組み立ててからでは塗装することができないところである。したがって従来技 術によると、この表面露出部分７が大気に晒されたままであって、泥水の侵入等 によってスリーブ１がこの表面露出部分７から錆びる虞がある。 またスリーブ１を単品状態で塗装またはメッキすれば、円筒部２の内周面およ びフランジ３のハブ４側の軸方向端面についてもこれらを塗装またはメッキする ことができる。しかしながらこの場合には、塗装後、スリーブ１をハブ４に嵌着 するときに塗料またはメッキの一部がハブ４によって削り取られてしまい、その 結果として円筒部２の内周面に表面露出部分７が生じ、スリーブ１がこの表面露 出部分７から錆びる虞がある。 In the above damper, in the sleeve 1, the exposed surface portion 7 that is not in contact with the hub 4 or is not covered by the elastic body 5 is formed on the inner peripheral surface of the cylindrical portion 2 and the axial end surface of the flange 3 on the hub 4 side. There is. The exposed surface portion 7 is surrounded by each member and cannot be painted after it is assembled. Therefore, according to the conventional technique, the exposed surface portion 7 is still exposed to the atmosphere, and the sleeve 1 may be rusted from the exposed surface portion 7 due to intrusion of muddy water or the like. If the sleeve 1 is painted or plated as a single piece, the inner peripheral surface of the cylindrical portion 2 and the axial end surface of the flange 3 on the hub 4 side can also be painted or plated. In this case, however, a part of the paint or plating is scraped off by the hub 4 when the sleeve 1 is fitted onto the hub 4 after painting, and as a result, the surface exposed portion 7 is formed on the inner peripheral surface of the cylindrical portion 2. May occur and the sleeve 1 may rust from the surface exposed portion 7.
