入しゴム２の内周面に生じた残留応力を除去していた。DETAILED DESCRIPTION OF THE INVENTION Conventionally, a torsional damper, which is attached to the crankshaft of an engine and used to reduce the vibration of the crankshaft, has an inertia ring 1 and a rubber 2. At the same time, the inner circumferential surface of the rubber 2 is vulcanized and bonded to the annular collar 3, and then the collar 3 is attached.
was press-fitted into the cylindrical portion 5 of the main body 4 fixed to the crankshaft to remove residual stress generated on the inner peripheral surface of the rubber 2.
しかし、カラー３を用いるため部品点数が多くコストが
増加し、また円筒部５が板金製であるため第１図下方へ
湾曲しやすいため、カラー３を円筒部５に圧入する作業
は難しかった。However, since the collar 3 is used, the number of parts increases, which increases cost, and since the cylindrical part 5 is made of sheet metal, it tends to bend downward in FIG. 1, making it difficult to press fit the collar 3 into the cylindrical part 5.
本発明は特許請求の範囲、に記載されたように構成され
ているので５部品点数が少なく、シかも円筒部を拡径す
るだけでよいため作業性もすぐれている。Since the present invention is configured as described in the claims, the number of parts is small, and the workability is also excellent because it is only necessary to expand the diameter of the cylindrical part.
以下２本発明の実施例について具体的に説明する。Two embodiments of the present invention will be specifically described below.
第２図に示す第１実施例において１本体ＩＯはクランク
軸に装着される支持面１１と水平方向に延びた円筒部１
２とからなり２円筒部１２は２点鎖線の形状に形成され
ている。ゴム１３は円環状に形成され２点鎖線の形状の
円筒部１２の外周に当接されている。イナーシャリング
１４は円環状に形成され、ゴム１３の外周に装着されて
いる。そして上記ゴム１３を加硫して上記イナーシャリ
ング１４と円筒部１２に接着する。次に円筒部１２をプ
レスにより拡径して第２図実線の状態に成形する。In the first embodiment shown in FIG.
2, and the cylindrical portion 12 is formed in the shape of a two-dot chain line. The rubber 13 is formed in an annular shape and is in contact with the outer periphery of the cylindrical portion 12 shaped like a two-dot chain line. The inertia ring 14 is formed in an annular shape and is attached to the outer periphery of the rubber 13. Then, the rubber 13 is vulcanized and adhered to the inertial ring 14 and the cylindrical portion 12. Next, the diameter of the cylindrical portion 12 is expanded by a press and formed into the state shown by the solid line in FIG.
したがって、従来のカラーを必要としないため部品点数
低減コスト低下が計れ、またゴム１３の内周の残留歪を
円筒部１２を拡径するだけで除去でき２作業性が良いも
のである。Therefore, since the conventional collar is not required, the number of parts can be reduced and the cost can be reduced, and residual strain on the inner circumference of the rubber 13 can be removed simply by expanding the diameter of the cylindrical portion 12, resulting in good workability.
第３図に示す第２実施例は第１実施例のゴムの硬度が大
きすぎる場合に、ゴム１３の容量を大きくしその分だけ
ゴム１３を軟いものとしたものである。In the second embodiment shown in FIG. 3, when the hardness of the rubber of the first embodiment is too high, the capacity of the rubber 13 is increased and the rubber 13 is made softer by that amount.
また、第２図において円筒部１２の内周にゴム１３を加
硫接着した場合には９円筒部１２を絞り加工して縮径し
ても同様の作用効、果が得られるものである。Further, in the case where the rubber 13 is vulcanized and bonded to the inner periphery of the cylindrical portion 12 in FIG. 2, the same effects and effects can be obtained even if the diameter of the cylindrical portion 12 is reduced by drawing.
