されている。Conventionally, this type of vibration damping device has been designed to perform rotational motion using a nut and threaded rod that are screwed together to compensate for the relative displacement in the axial direction during vibration D between two support members connected to the allocation target and the structure, respectively. An inertial vibration damping device is known that converts the rotational motion into A mechanism has been proposed that incorporates a mechanism 411 for speeding up the rotation, thereby reducing the size of the inertial body and also being able to cope with low-cycle vibration F. ing.

いる。A detailed example of the present invention will be described below with reference to the drawings. The main cylinder 1, which is one of the supporting members, has a handle 1 on the outside of the pane lid 1a.
b, through which it can be connected to an allocation target such as a structure or piping system. Further, one end of a first threaded rod 2 extending in the direction of the solid axis is fixed to the inside of the lid 1a at one end.

The other end of the sub-tube 3 is inserted into the main 1f%'il so as to be able to move in and out in the axial direction, and the other end lid 3c is inserted into the main 1f%'il.
The threaded rod 2 is freely moved in and out. Lid 3 of secondary cylinder 3
Inside a, there is a threaded rod 4 of the thread 2 extending in the direction of the solid axis.
One end is fixed. The pitch of the second threaded rod 4 is
It shall be smaller than that of the first threaded rod 2.

First and second pole nuts 6.7 are fixedly screwed onto the threaded rods 2, 4 of. Therefore, the first and second threaded rods 2, 4 are connected to the first and second pole nuts 6, respectively.
．． 7, and can freely rotate relative to the inertial body 5 and move in and out in the axial direction.

This M control device is used by connecting either the main cylinder 1 or the sub cylinder 3, 10,000 of which is connected to the object to be purchased, and the other to the object of allocation. If a vertical displacement occurs between the allocation target and the construction due to temperature sharpening, the jjfl element 5 slowly rotates together with the bolt 1 and the second nut 6.7. And this can be tolerated without difficulty.

The 119-force body 5 is unable to follow the rotation caused by the vibration caused by the vibration, and this 1U-force resistance becomes a large reaction force against the vibration.

ｉ、ｌに適用可能である。In addition, since this mating uses two threaded rods 2 and 4 and two corresponding pole nuts 6.7,
The rotation speed will be increased compared to the case where the rotational motion is obtained by screwing the tension rod and the nut together. That is, for example, if the thread pitch of the first screw f7g2 is P, that of the second threaded rod is P2, and PI>P2, then the first pole nut 6 and the first threaded rod 2 are relatively When only the PI is transferred, Paul Nut 7 and Paul Nut 6 are moved to 1.
P2 in the axial direction relative to the second threaded rod 4
move only. Therefore, in order to rotate the pole nut 6.7 and the inertial body 5 once, it is necessary to use the first two threaded rods A.
g mlJ. In other words, compared to the combination of a flower nut and a threaded rod, the present invention is not limited to the embodiment shown in the figure. For example, there are various known allocation systems that indirectly use the writing function of NUT 6.7.
It is applicable to i, l.

ことができるという効果が得られる。As explained above, the present invention provides the threaded rods 2 and 4, respectively.
Threaded rods 2 of the main cylinder 1 and the secondary cylinder 3, which are supporting members equipped with
4 are respectively screwed together with first and second nuts 6.7 integrally connected to each other, and due to the relative axial displacement bi)r between the nuts 6.7 and the threaded rods 2, 4, the nuts 6, Since the 14-mer body on 7 was purchased to rotate at an increased speed, the speed increasing mechanism could be made smaller and lighter, with a relatively large increase in speed by 1! The effect is that the ratio can be obtained.
