    • PURPOSE:To strengthen the connection between the boss and the flywheel body using the boss of simplified shape by forming an annular groove around the hole in the flywheel body for inserting the boss, and by placing and caulking the annular protrusion in the annular groove to prevent the metal flow. CONSTITUTION:Annular grooves 104, 105, 106 having the V-shape section are formed concentrically ariund the hole 102 in the flywheel body. The male mold processes by drawing the flywheel material in the shape of a cup-like flywheel. At this moment, annular protrusions 502, 804 and 805 bite in the flywheel material to prevent the material from being displaced to deform the hole 102 for inserting the boss. In the last process of caulking, the caulked part crushes the peripheral area of the boss insertion hole 102. At this moment, as the annular protrusion 804 of the male mold is in the annular groove, the direction of the metal flow around the boss insertion hole 102 is ristricted as shown with the arrow (a), the clearance is prevented from being provided between the boss insertion hole 102 and boss 2.
    • 目的:通过在飞轮体的孔周围形成一个环形槽,用于插入凸台,并通过在环形槽中放置和铆接环形突起,来加强凸台与飞轮体之间的连接,以便简化形状的凸台 金属流。 构成:具有V形截面的环形槽104,105,106同心地形成飞轮体中的孔102。 阳模通过将飞轮材料拉成杯状飞轮的形状来进行加工。 此时,环形突起502,804和805咬在飞轮材料中以防止材料移位以使孔102变形以插入凸台。 在最后的铆接过程中,铆接部破碎凸台插入孔102的周边区域。此时,随着阳模的环状突起804处于环形槽中,金属流在凸台插入件周围的方向 孔102如箭头(a)所示地排列,防止了在凸台插入孔102和凸台2之间设置间隙。

    • PROBLEM TO BE SOLVED: To provide a torsional damper pulley improving versatility and easily manufacturable with reduced manufacturing costs.
      SOLUTION: This torsional damper pulley is constituted of a hub 11 fixed to a rotary shaft of an internal combustion engine, an annular pulley body 10 arranged coaxially with an annular fixing part 11b on an outer periphery of the hub 11 and an elastic body 13 interposed between an outer peripheral surface of a flange and an inner peripheral surface of the pulley body 10. The pulley body 10 is constituted of an annular frame body 12 having a substantial U-shape in cross section and having a recessed part 15 opened on one side in the shaft direction and an annular inertial mass body 14 inserted and fixed into the recessed part 15 in the shaft direction. The inertial mass body 14 is made of laminated bodies coupled by overlapping circular ring plates 14a. The inertial mass body 14 is fixed by being pressed into the recessed part 15.
