    • PURPOSE:To control vibration produced in a long bolt by compressing and deforming a tubular vibration control member which is longer than an insertion hole for the bolt and inserted between the bolt and the insertion hole with a gap by screwing the bolt, to be brought into contact with the outer peripheral surface of the bolt and the inner wall surface of the insertion hole. CONSTITUTION:A stud bolt 1 is inserted in an insertion hole 4 formed in a cylinder head 2 and a cylinder block 3, so that both the cylinder head 2 and the cylinder block 3 are fastened to a crank case 5 and fixed thereto. A vibration control member 6 is inserted in the insertion hole 4. The vibration control member 6 is a metallic thin wall tubular member a little longer than the insertion hole and inserted between the stud bolt 1 and the insertion hole 4 with a gap. When the stud bolt 1 is screwed in, a slidng curved portion 7 is compressed and deformed, so that bending lines P1, P3 are brought into contact with the outer peripheral surface of the stud bolt 1 and a bending line P2 is brought into contact with the inner wall surface, whereby the vibration of the stud bolt can be controlled.
    • 目的:通过压缩和变形长度大于螺栓插入孔的管状振动控制构件来控制在长螺栓中产生的振动,通过螺栓拧入插入螺栓和插入孔之间的间隙,使其进入 与螺栓的外周表面和插入孔的内壁表面接触。 构成:将双头螺栓1插入到形成在气缸盖2和气缸体3中的插入孔4中,使得气缸盖2和气缸体3都被紧固到曲轴箱5并固定在其上。 振动控制构件6插入插入孔4中。振动控制构件6是比插入孔稍长的金属薄壁管状构件,并且间隔地插入在双头螺栓1和插入孔4之间。 当双头螺栓1旋入时,滑动弯曲部分7被压缩和变形,使得弯曲线P1,P3与双头螺栓1的外周表面接触,并且弯曲线P2与 内壁表面,从而可以控制双头螺栓的振动。
