Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a shock absorbing device that dampens mechanical vibrations generated from equipment and the like.

(Prior Art) Conventionally, as shown in FIG. 2, a substantially cylindrical buffer section 10 having flexibility in both the axial direction and the radial direction, and a coaxial direction on the upper and lower surfaces of the buffer section 10, are provided. A shock absorbing device is known which includes mounting sections 20 and 21 provided at the upper mounting section 2 of the buffer section.
Connect a device that generates vibration to the lower mounting part 2.
By attaching 1 to a foundation, etc., it can buffer vibrations transmitted from the device to other devices via the foundation, or conversely, dampen vibrations transmitted from other devices to the device via the foundation. I was letting it happen.

(Problems to be solved by the invention) In the conventional shock absorbing device, since it has flexibility both in the axial direction and in the direction orthogonal to the axis, the shock absorbing portion 10 is attached to the mounting portion 20. Deformation occurred in the radial direction due to the weight or vibration of the equipment. For this reason, there was a problem in that the cores of the devices connected via the buffer device were tilted.

(Purpose of the invention) In view of the above-mentioned conventional problems, the present invention aims to provide a shock absorber that buffers vibrations generated by equipment and alleviates deformation in the direction orthogonal to the axis due to the weight or vibration of the equipment. be.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a substantially column-shaped buffer section that is flexible in both the axial direction and the direction orthogonal to the axis, and the buffer section. In a shock absorbing device equipped with mounting parts coaxially provided on the upper and lower surfaces, a rigid cylindrical frame with an open upper face is provided around the shock absorbing part, and the lower face of the frame has a mounting part provided on the same axis. The bottom surface of the buffer part is fixed, and the upper end of the frame and the upper end of the buffer part are connected by a support plate formed of a thin plate member, and the support plate has elasticity in the axial direction. It is characterized by having a restrictive property in the direction orthogonal to the axis.

(Function) According to the present invention, vibrations and shocks generated from the device are buffered by the buffer section of the shock absorber, and transmission of vibrations and shocks to or from other devices is prevented. Attenuated. In addition, a rigid frame is provided around the buffer section, and a support plate is provided between the frame and the buffer that has elasticity in the axial direction and restraint in the direction perpendicular to the axis. By connecting, deformation of the buffer section in a direction orthogonal to the axis is restrained.

(Embodiment) FIGS. 1 and 3 show an embodiment of the present invention, and the same components as those of the conventional example are denoted by the same reference numerals. That is, 10 is a buffer section, which includes a cylindrical section 11 formed of a flexible member such as silicone rubber, a silicone gel 12 filled inside the cylindrical section 11, and openings at the top and bottom of the cylindrical section 11. It is constructed of two airtight steel lids 13 that are attached to the main body.

20 and 21 are the lid 13 and the frame 3, respectively.
0, and the mounting parts 20 and 21 have seats 20a and 21a, and male screw parts 20b and 21, respectively.
b is provided.

30 is a cylindrical steel frame with an open top;
The buffer section 10 is housed inside the frame body 30 on the same central axis, and the bottom surface 31 of the frame body 30 and the bottom surface 13a of the lid 13 of the buffer section 10 are in close contact.
Further, there is a space between the side wall 32 of the frame 30 and the side wall outer surface 11a of the cylindrical portion 11 of the buffer portion 10. A ring-shaped support plate 40 is horizontally connected between the upper end surface 32a of the side wall 32 of the frame body 30 and the upper surface 13b of the upper lid 13 of the buffer section,
The support plate 40 is formed of a thin steel plate having a concentrically corrugated shape.

According to this embodiment, the mounting portion 21 of the shock absorber
is attached to the foundation, and the attachment part 2 of the shock absorber is also attached to the base.
0 is attached to equipment that generates vibrations or shocks, the vibrations or shocks from the equipment are buffered by the flexible buffer section 10, and are not transmitted to other equipment via the foundation on which the mounting section 21 is attached. Vibration or shock transmission is damped. Further, the support plate 40 horizontally connected between the buffer section 10 and the rigid frame 30 has elasticity in the axial direction, but has restraint in the direction perpendicular to the axis, so that the buffer section It has a restraining force against deformation in a direction perpendicular to the axis of 10.

Therefore, the problem of tilting of the axis between the two devices attached via the shock absorbing device is alleviated.

(Effects of the invention) As explained above, according to the invention, not only vibrations can be damped by the buffer part having flexibility in the axial and radial directions, but also vibrations can be damped by the buffer part and the frame having rigidity. The support plate, which is horizontally connected between the buffer parts, has elasticity in the axial direction, but has restraint in the direction perpendicular to the axis, so it exerts a restraining force against deformation in the direction perpendicular to the axis of the buffer part. have

Therefore, the problem of tilting of the axis between two devices axially connected via the shock absorbing device is alleviated.
