이때, 상하부무기질적층시트(10,11)는 제1금속톱니형본체(20)과 플랜지 사이에 위치하면서 플랜지의 체부압시 제1금속톱니형본체(20)의 톱니를 채워 그 금속간의 불완전한 접촉표면을 완벽하게 보완해주는 작용을 하게 되고, 플랜지의 금속경도가 제1금속톱니형본체(20)의 금속경도보다 작을 경우 과체부압시 제1금속톱니형본체(20)에 의한 플랜지의 접촉손상을 차단하도록 구성되어 있다.At this time, the upper and lower inorganic laminated sheets (10, 11) is located between the first metal toothed body 20 and the flange, and fills the teeth of the first metal toothed body 20 during the body pressure of the flange incomplete contact surface between the metal And the metal hardness of the flange is less than the metal hardness of the first metal toothed body 20 to block the contact damage of the flange by the first metal toothed body 20 during overpressure. It is configured to.

한편, 본 발명의 다른 실시예에 따르면, 도3에 도시한 바와 같이 제2금속톱니형본체(21)는 제1금속톱니형본체(20)와 달리 톱니의 산과 골이 각각 둥근 철면(凸面)을 이루도록 형성되어 있다.On the other hand, according to another embodiment of the present invention, as shown in FIG. 3, unlike the first metal toothed body 20, the second metal toothed body 21 is a convex surface of the teeth and the valleys of the tooth, respectively rounded (凸面) It is formed to achieve.

이때, 제2금속톱니형본체(21)는 제1금속톱니형본체(20)와 동일한 작용을 하면서 급격한 열변화에 의한 열수축 또는 열팽창과 같은 급격한 열변형으로 유격이 발생되지 않도록 보완하는 작용을 하게 된다.At this time, the second metal toothed body 21 has the same function as the first metal toothed body 20 and complements such that the play does not occur due to rapid thermal deformation such as thermal contraction or thermal expansion due to rapid thermal change. do.

그리고, 본 발명은 그 또 다른 실시예에 따르면, 도4에 도시한 바와 같이 그 상하면에 평면 또는 둥근 철면(凸面)의 산과 골을 이루는 톱니형(Serrated Type)의 요철이 동심원을 갖도록 구비되는 제1,2금속톱니형본체(20,21)와, 상기 제1,2금속톱니형본체의 상하면에 각각 접착되는 상하부무기질적층시트(10,11)로 구성되어 있다.In addition, according to another embodiment of the present invention, as shown in FIG. 4, the upper and lower surfaces of the present invention are provided such that serrated type irregularities forming valleys with flat or rounded iron surfaces have concentric circles. The first and second metal toothed bodies 20 and 21 and the upper and lower inorganic laminated sheets 10 and 11 adhered to upper and lower surfaces of the first and second metal toothed bodies, respectively.

여기서, 본 발명의 또 다른 실시예는 금속평면외륜(30)을 생략하도록 구성함으로써 보다 저렴한 제조원가를 구현할 수 있는 장점이 있다.Here, another embodiment of the present invention is configured to omit the metal plane outer ring 30, there is an advantage that can be implemented a lower cost manufacturing.

이와 같이, 본 발명의 상세한 설명에서는 구체적인 실시예에 관해 설명하였으나, 이는 본 발명의 범주에서 벗어나지 않는 한도내에서 여러가지 변형이 가능함은 물론이다.Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

그러므로, 본 발명의 실질적인 범위는 상술된 실시예에 의해 한정되어져서는 안되며, 후술하는 청구범위 뿐만 아니라 청구범위와 균등한 구성에 의해 정해져야 함은 당연하다.Therefore, it should be understood that the practical scope of the present invention should not be limited by the above-described embodiments, but should be determined by the constitution equivalent to the claims, as well as the claims described below.
