Abstract

PURPOSE: An anti-vibration band for a generator is provided to reduce a noise and a vibration of the generator by reducing a magnitude of a force applied on the generator, by pressing a compression band assembled on an outer circumference of a key bar to a core assembled on the key bar portion. CONSTITUTION: An anti-vibration band for a generator includes a plurality of segments(11) having uniform curvatures along with a circumference. The plurality of segments are linked with one another.

Description

발전기용 진동방지 밴드{Band for Prevention Vibration of Generator}Band for Prevention Vibration of Generator

본 발명은 발전기용 진동방지 밴드에 관한 것으로, 보다 상세하게는 밴드를 발전기의 부품인 코어에 압착설치함으로써, 발전기에 가해지는 진폭을 최소화시켜 발전기의 소음 및 진동을 감쇠시킬 수 있도록 한 것이다.The present invention relates to an anti-vibration band for a generator, and more particularly, by compressing and installing the band on a core that is a part of a generator, thereby minimizing the amplitude applied to the generator to attenuate the noise and vibration of the generator.

일반적으로 발전기의 소음 및 진동을 줄이기 위해 설계 단계에서 발전기 자체의 고유 진동수를 2극 발전기의 경우 가진 진동수 60Hz,120Hz를 피해 설계하였다. 이는 발전기 설계의 기본 개념이고 더불어 컴프레이션 밴드(COMPRESSION BAND)를 키 바(KEYBAR)에 감아 코어를 압착시키는 방법으로 진폭을 줄이는 방법으로 소음과 진동을 효과적으로 방지할 수 있으나, 이러한 감진효과를 구체화기 위한 장치가 없었다.In general, in order to reduce the noise and vibration of the generator, the natural frequency of the generator itself was designed to avoid the 60Hz and 120Hz frequency of the two-pole generator. This is the basic concept of the generator design, and the compression band is wrapped around the keybar to press the core to reduce the amplitude, which effectively prevents noise and vibration. There was no device for it.

본 발명은 상기와 같은 문제점을 해소하기 위해 제안된 것으로, 링 모양의 밴드를 제작하고, 이 밴드를 발전기의 부품인 코어를 압착시키는 방법으로 설치함으로써, 발전기에 가해지는 진폭을 줄여 발전기의 소음,진동을 감쇠시킬 수 있도록 하는 점에 목적이 있다.The present invention has been proposed to solve the above problems, by manufacturing a ring-shaped band, and by installing the band by pressing the core which is a part of the generator, by reducing the amplitude applied to the generator noise of the generator, The purpose is to be able to dampen vibrations.

11 : 세그먼트 12 : 밴드11: segment 12: band

상기와 같은 목적을 달성하기 위한 본 발명은 일정한 곡률을 이루는 다수개의 세그먼트로 구성되고, 이 세그먼트를 서로 연결하여 밴드로 제작되는 점에 특징이 있다.The present invention for achieving the above object is composed of a plurality of segments forming a constant curvature, it is characterized in that the segments are connected to each other to be produced as a band.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

첨부된 예시도면 도 1은 컴프레이션 밴드의 구조를 나타낸 도면으로 발전기내부에서의 작업성을 고려하여 하나의 링을 5개의 세그먼트(SEGMENTS)(11)로 구성하고 각 세그먼트(11)를 서로 연결하여 하나의 밴드(12)로 제작된다.1 is a view illustrating a structure of a compression band. In consideration of workability in a generator, a single ring is formed of five segments 11 and each segment 11 is connected to each other. It is made of one band 12.

참고적으로, 세그먼트(11)간에는 별도의 연결재를 통해 체결되거나 용접된다.For reference, the segments 11 are fastened or welded through a separate connecting member.

위와 같이 본 발명은 컴프레이션 밴드를 키 바의 외경부에 조립하여 키 바부에 조립된 코어를 압착시킴으로써, 발전기에 가해지는 가진력의 진폭을 줄여 발전기의 소음,진동을 감쇠시키는 효과가 있다.As described above, the present invention assembles the compression band to the outer diameter of the key bar and compresses the core assembled to the key bar, thereby reducing the amplitude of the excitation force applied to the generator, thereby reducing the noise and vibration of the generator.
