Conventionally, there has been a viscous rubber damper as shown in FIG. That is, in the figure, reference numeral 1 denotes a disk-shaped metal hub that is attached to the rotating shaft side of a device (not shown), and 2 denotes metal plate-shaped members 2a and 2b having substantially L-shaped cross sections facing each other, which are connected to each other at their outer peripheries. The welding 2c forms a substantially U-shaped cross section, and is concentric with the hub 1.
The vibration rings 3, 3 are arranged so as to surround the outer diameter of the vibration ring 2, and are applied between the inner diameter of the annular groove 4 of the vibration ring 2 and the opposite radial surfaces 1a and 1b of the hub 1. It is an annular rubber bonded with sulfur. A viscous fluid 6 such as silicone is sealed in a sealed cavity 5 formed by the outer diameter of the hub 1, the outer diameter of the annular groove 4 of the vibration ring 2, and the outer circumference of the annular rubbers 3, 3. The structure is such that the viscosity of the viscous fluid 6 combines with the elasticity of the annular rubbers 3 to produce a damping effect.

The above conventional viscous rubber damper has a hub 1
Since there is still room for the vibration ring 2 to move relative to the vibration ring 2 in the axial and radial directions, if there is even a slight imbalance in the machining accuracy of the vibration ring 2 or the annular rubbers 3, 3, the vibration ring 2 will move during rotation. 2 is hub 1
Contact with the space H1,
There is a problem that H2 and H3 change and the damping effect of the viscous fluid 6 cannot be kept constant.

In view of the above problems, the present invention has been devised to prevent the vibration ring from moving in the axial direction and in the radial direction with respect to the hub. A vibration ring with a substantially U-shaped cross section that surrounds the outer diameter part is concentrically connected via an annular rubber, and a sealed air space formed by the hub, the vibration ring, and the annular rubber.
In a viscous rubber damper having a viscous fluid sealed therein, a sliding bearing having a substantially U-shaped cross section is mounted on the outer diameter side of the hub within the sealed space.

A sliding bearing having a substantially U-shaped cross section is mounted on the outer diameter side of the hub in the sealed space, and the bearing is used as a guide to restrict the movement of the vibration ring only in the circumferential direction.

い。 That is, as shown in FIG. 1, a porous oil-impregnated metal is placed between the outer circumferential edge 1c of the hub 1 and the outer circumferential edge 4c of the annular groove 4 of the vibration ring 2, which corresponds to the outer circumference of the sealed cavity 5. , a slide bearing 7 made of sintered metal, gunmetal, etc. and having a substantially U-shaped cross section is mounted, and the vibration ring 2 is mounted with the slide bearing 7 as a guide.
movement is restricted only in the circumferential direction. Therefore, since the vibration ring 2 does not move axially or radially relative to the hub 1, both 1 and 2
The damping effect of the viscous fluid 6 can be stabilized by preventing wear due to contact between the two and keeping the distance between the sealed spaces 5 constant. Note that the slide bearing 7 may be divided into a plurality of pieces in the circumferential direction.

As explained above, the viscous rubber damper of the present invention has a sliding bearing with a substantially U-shaped cross section installed in the sealed space formed by the hub, the vibrating ring, and the annular rubber. It is designed to prevent movement and radial movement, thereby preventing wear due to contact between the hub and the vibration ring and stabilizing the damping effect caused by the viscous fluid.
