耐蝕性を損う欠点があつた。 As shown in Fig. 2, a commonly used vibration isolator consists of a damper cable 1, such as a galvanized steel stranded wire, with weights 2 fixed to both ends.
It is suspended from a wire 4 via a clamp 3. If such a vibration isolator is used in an area with high salt content or an area with high sulfur dioxide gas such as a chemical factory, the vibration isolator will be damaged within a few years after installation. Red rust occurs on the damper cable, which shortens the life of the damper cable, and the red rust stains the vibration isolator. In addition, a damper cable made of stranded steel wire covered with a rubber-like elastic material is used, but the compressed and fixed part between the damper cable and the weight is not watertight, allowing some rainwater to enter, resulting in corrosion resistance. There were drawbacks that impaired the quality of the product.

る。 In view of this, the present invention has devised a simple manufacturing method for a vibration isolator with excellent corrosion resistance.After attaching weights to both ends of a damper cable to construct a vibration isolator, this is heated and melted. It is characterized by providing a coating of the rubber-like elastic material on the surface of the vibration isolator by immersing it in a liquid mainly composed of a rubber-like elastic material.

れる。 Figure 1 shows an example of a corrosion-resistant vibration isolator manufactured by the method of the present invention. 1 shows a damper cable made of stranded steel wire (which may or may not be galvanized); A vibration isolator, in which a weight 2 is fixed, a damper cable 1 is held at the center by a clamp 3, and suspended from an electric wire 4, is immersed in a liquid mainly composed of a rubber-like elastic body melted by heating. Therefore, a coating 5 of a rubber-like elastic material was provided on the surface of the corrosion protection device. If the desired thickness of the film 5 cannot be obtained by one soaking, it can be easily obtained by repeating the soaking two or three times.

たり安定したゴム状弾性体の被膜を維持し得る。 As the rubber-like elastic body, natural rubber outer vinyl, silicone rubber, chloroprene, and other elastic substances are used.After being attached to the electric wire as a vibration isolator, the damper cable and weight will be displaced, but the coating has elasticity, so it will not displace. Therefore, the corrosion resistance of the damper cable and the weight can be ensured without impairing the vibration-proofing characteristics of the damper cable. Furthermore, since the film of the rubber-like elastic material coated on the surface of the damper cable is formed by immersing it in a liquid mainly composed of a heated and melted rubber-like elastic material, the film is formed by filling the gaps between the twists of the damper cable. Ru. Therefore, when the damper cable vibrates, the coating is also reliably deformed, and the vibration energy can be consumed due to the elastic hysteresis loss, which has the effect of improving the anti-vibration effect as well as the corrosion protection of the damper cable. Moreover, since the rubber-like elastic body covers the damper cable, if excessive bending stress is applied to the rubber-like elastic body, the rubber-like elastic body in the form of a coating will cover the damper cable. It is possible to maintain a stable coating of the rubber-like elastic material over a long period of time without causing any cracks or the like in the rubber-like elastic material.

A vibration isolating device with a long life can be obtained, and the vibration isolating effect can be improved.
