CONSTITUTION:A supporter 1 is formed of a body 1a and connecting plates 1b and 1c and has through holes 1d, 1e and 1f directed in the axial directions X, Y and Z. An object 3 to be supported is formed of a body 3a and connecting plates 3b and 3c and has through holes 3d, 3e and 3f directed in the axial directions X, Y and Z. A shaft 5 is pierced through the through holes 1d and 3d and attached with a clasp 6, and a spring 7 is provided between the clasp 6 and the bodies 1a and 3a. Shafts 8 and 11 are likewise pierced through the through holes 1e and 3e and 1f and 3f, respectively, clasps 9 and 12 are attached to the shafts 8 and 11, respectively, and springs 10 and 13 are provided between the clasp 9 and the connecting plates 1b and 3b and between the clasp 12 and the connecting plates 1c and 3, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION This @ Ming relates to a vibration isolating device using a spring.

In the conventional vibration isolator, a rubber (IQ) is disposed between a support member (1) and a temporary support member (3) as shown in Fig. 1.

For this reason, there was a drawback that sufficient vibration damping performance could not be maintained for many years due to deterioration of the rubber 06).

This invention was made to eliminate the above drawbacks.
Provides a vibration isolator (l-) that does not deteriorate and has good vibration isolating performance.

The figures will be explained below. In Figures 1 to 3,
(1) is the vibration f! of the cass breaker etc. :Equipment that generates (

It is rolled up by the connecting plate (l b) (lc) provided in a). (14), (le) (If) are the through holes from 1 to 3 that are bent in the main body (la) and the connecting plates (lb) (lc,), and the X It penetrates in each axis direction: axis, Y axis, and z axis. +31 indicates equipment that is prone to failure due to vibration, such as a waste detector (4)
It is a supported member with an IX capacity of 0.1, and is structured by the main body (3a) and the connecting plates (3b) and (3c). (3d

) (3c) A through hole that penetrates in the X, Y, and Z axis directions. (5) is the hole and the fourth through hole (la
) (3d), and clasps (6) are attached to both ends and the center of the shaft. (7) is a coiled metal spring, which is pressed and arranged at the IF body (la) (3a) and the stop @ (61+ij. (8)
) is a second shaft that passes through the second and fifth through holes (le) (3e), and has clasps (9) fixed to both ends and the center. (lO) is the second spring of coiled metal, and the clasp (

(10) is a third shaft passing through the second and O6 through-holes (If) (8f), and a stopper α powder is fixed to both ends and the center. (13) is a third coiled metal spring, which is compressed and arranged between the stopper t121 and the connection &(lc) (8c).

Next, the operation will be explained. Now, when the device (2) swings in the Y1 direction (FIG. 2, vertical direction), the second spring 10) vibrates and absorbs the auxiliary energy. Also,
When the mechanism (2) vibrates in the X-axis direction (second direction, left and right direction), the first spring (7) stretches and absorbs the vibration energy. 2-axis direction (Fig. 2, perpendicular to the drawing) During vc vibration-assisted vibration, the third spring -(+31) expands and contracts to absorb the vibration energy t-.Each axis i51 +

1) is not likely to restrict the displacement in the vibration direction between the support member 11+ and the plate support member (3). Therefore, the vibration damping performance is good regardless of the direction of vibration.

Above 51 The man has each coiled spring (7 + 1101 H
Although the anastomotic VC using K was explained, as shown in the sixth example, the same effect can be obtained even if the corrugated washer (14) and the flat plate 05 are aligned by -1.

Note that the above explanation is based on the case where each spring [51 (81 + 10) is used to support each spring [7 + tlol (+31)], but the spring is used as a leaf spring (not shown) and its ends are connected to each other. Board (lb) (lc) (8b)
(8c) or the main body (la) (8a), the shaft [51[81(101) can be omitted.

Note that *t y'' described above deals with the three-dimensional vibration jνJ of the Y axis, YIiIIIll, and Z qa, but if the cutting direction is two-dimensional and the relief is only in the horizontal direction, the Y axis and Y Spring pressure can be applied to both directions of the shaft.

As described above, according to the present invention, at least 2IJ
By connecting the supporting member and the supported member with multiple springs that generate spring pressure in the 111 direction, vibration isolation performance can be improved without deterioration.
