ンパに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a torsional damper that is attached to a rotating shaft such as a crankshaft of an internal combustion engine and absorbs torsional vibration of the same shaft.

め、このクランクシャフトにトーショナルダンパを取り
付けて捩り振動を吸収することが行われている。(Prior Art) In an internal combustion engine, especially a diesel engine, the crankshaft, which rotates around its axis in response to the reciprocating motion of the pistons, experiences complex torsional vibrations due to the periodic motion of the pistons or the unbalance of the piston crank mechanism. Therefore, a torsional damper is attached to the crankshaft to absorb the torsional vibration.

動が吸収されるようになっている。Such a torsional damper includes a rigid inner cylindrical member fixed to a rotating shaft such as a crankshaft, and a rigid outer cylindrical member serving as a damper mass disposed concentrically with the inner cylindrical member on the outside thereof, Among these two, an elastic member such as rubber as a buffer is interposed between the outer cylinder member,
Torsional vibrations are absorbed by this elastic member and the damper mass rigid outer cylinder member.

ある。By the way, such a torsional damper is constructed by applying a vulcanized adhesive to the outer peripheral surface of the inner cylinder member and the inner peripheral surface of the cylinder member, and in a state in which they are arranged concentrically, there is a gap between the inner and outer cylinder members. A vulcanization adhesive type method in which unvulcanized rubber is injected and vulcanized and bonded, or an elastic member previously vulcanized into a cylindrical shape is press-fitted at a predetermined compression ratio between the inner and outer cylindrical members. A press-fit type system is well known.
（発明が解決しようとする課題）
しかしながらかかる従来の形態のトーショナルダンパは
、製造が比較的容易であるものの以下に述べるような欠
点があった。(Problems to be Solved by the Invention) However, although such conventional torsional dampers are relatively easy to manufacture, they have the following drawbacks.
即ち加硫接着タイプ方式のものは１弾性部材に予備圧縮
が付与されていないため、弾性部材と剛性内、外筒部材
との各々の接着界面に弾性部材の成形による圧縮歪が残
留するとともに、ダンパ使用時にこの接着界面に応力集
中が生ずるなどが原因して、弾性部材の剥離現象が生じ
、その結果弾性部材と剛性内、外筒部材の各々との間に
滑りが生じ、終にトルク伝達機能を喪失するに到るとい
う問題がある。That is, in the case of the vulcanization adhesive type method, no pre-compression is applied to one elastic member, so compressive strain due to molding of the elastic member remains at each adhesive interface between the elastic member, the inner rigid member, and the outer cylinder member. When the damper is used, stress concentration occurs at this adhesive interface, which causes the elastic member to peel off, resulting in slippage between the elastic member and the rigid inner and outer cylinder members, which ultimately results in torque transmission. There is a problem that this leads to loss of function.
一方圧入タイブ方式のものは、安価なコストで製造でき

履歴により弾性部材かへたると、弾性部材と剛性内、外

合が生ずるのである。On the other hand, the press-fit type type has the advantage that it can be manufactured at low cost, but there are restrictions on the wall thickness of the elastic member (because the rigidity and the gap between the outer cylinder members are fixed), and in reality If the press-fitting allowance is not sufficient and the elastic member weakens due to heat history during use, slippage will occur between the elastic member and the rigid inner and outer cylinder members, resulting in the above-mentioned problems.

接着して成ることにある。(Means for Solving the Problems) The torsional tamper of the present invention has been devised based on the above circumstances, and its gist is that the rigid inner cylinder member is attached to the rotating shaft, and the rigid inner cylinder member is attached to the rigid inner cylinder member. The elastic member interposed between the rigid outer cylinder member, which is a damper mass, and which is arranged concentrically with the damper mass, is vulcanized and molded in advance into a band-like or cylindrical shape, and the outer peripheral surface of the inner cylinder member and the inner peripheral surface of the outer cylinder member are And/or after applying an adhesive mainly composed of chlorosulfonated polyethylene to both surfaces of the elastic member to form an adhesive layer, apply a lubricant that is compatible with the elastic member to the outer peripheral surface of the inner cylinder member and the outer cylinder. It is applied to the inner circumferential surface of the member and/or both sides of the elastic member, press-fitted between the inner and outer cylindrical members at a predetermined compression rate, and then glued together.

予備圧縮された状態でこれら内。(Operations and Effects of the Invention) The torsional damper of the present invention is made by bonding an elastic member and inner and outer cylinder members, and these members are pre-compressed.
外筒部材間に介装されているので接着界面に過大な応力
集中は生じず、従って応力集中に基づく接着界面での剥
離現象を生じない。Since it is interposed between the outer cylindrical members, excessive stress concentration does not occur at the adhesive interface, and therefore no peeling phenomenon occurs at the adhesive interface due to stress concentration.
また弾性部材が内、外筒例れの部材にも接着されている

Therefore, it has good durability and ensures reliable power transmission.

造も容易である。Further, in the torsional damper of the present invention, since the elastic member is press-fitted with lubricant applied to the press-fit surfaces of the elastic member and the inner and outer cylindrical members, it is easy to straighten the elastic member. It is also easy to manufacture the torsional damper itself.

Glue the outer cylinder member. Therefore, the torsional damper of the present invention has good adhesive strength, and the adhesive mainly composed of chlorosulfonated polyethylene has high adhesive strength at high temperatures, so it can be used under severe temperature conditions near engines.

内、外筒部材に接着せしめた。Next, after immersing the elastic member in lubricating oil so that both sides of the elastic member are coated, the elastic member is rolled into a cylinder and a predetermined compression rate (25% in the example) is applied between the inner and outer cylinder members. An elastic member was press-fitted between the inner and outer cylinder members to form a cylindrical shape. Furthermore, this was adhered to the inner and outer cylinder members by various adhesion methods (post-adhesion).

After molding with sulfur and applying an adhesive mainly composed of chlorosulfonated polyethylene to the outer peripheral surface of the inner cylinder member, the inner peripheral surface of the outer cylinder member, and/or both surfaces of the elastic member to form an adhesive layer, the elastic A lubricating oil that is compatible with the members is applied to the outer peripheral surface of the inner cylinder member, the inner peripheral surface of the outer cylinder member, and/or both sides of the elastic member, and the elastic member is press-fitted between the inner and outer cylinder members at a predetermined compression ratio. After that, the torsional damper is made by gluing the two together.
