본 발명은 소음 및 진동방지용 고온 철강롤러에 관한 것으로서, 이를 보다 구체적으로 설명하자면, 철강제품 등의 중량물 이송에 사용되는 철강롤러의 구조를 개선하여 롤러의 강도, 수명, 가공성 등을 향상시킴은 물론 장기간 사용에도 롤러의 편마모 현상과 파손 등을 예방하여 주고 나아가 롤러의 생산비용을 현저히 절감토록 하여 줌에 그 목적을 가지고 발명된 것이다. The present invention relates to a high temperature steel roller for preventing noise and vibration, and more specifically, to improve the structure of the steel roller used for transporting heavy materials such as steel products, as well as improving the strength, service life, workability, etc. of the roller. It is invented with the purpose to prevent uneven wear and breakage of the roller even in long-term use and to significantly reduce the production cost of the roller.

일반적으로 철강롤러는 철강산업 분야에서 생산되는 철강제품(고중량의 철판 등과 같은 중량물)을 이송시키기 위하여 사용되는 롤러이다. In general, steel rollers are rollers used to transport steel products (heavy weight such as heavy steel plates) produced in the steel industry.

즉, 위와 같은 철강롤러를 간략하게 설명하자면,That is, to briefly explain the above steel roller,

본 출원인이 선출원한 실용신안 20-2003-0001611호와 같이 내부 중심위치로 지지대에 의해 철강파이프가 내설된 내부회전체 양측부로 각각 회전축이 열가공결합을 통해 억지 끼움 된 다음 상기 내부회전체 외부연으로 하나 이상의 회전고무롤러와 내열강으로 제작된 결합롤러가 순차적으로 반복 설치되어 고정너트에 의해 고정되되, As shown in Utility Model No. 20-2003-0001611, filed by the present applicant, the rotary shafts are inserted into both sides of the inner rotating body in which the steel pipes are built by the support to the inner center position, and the rotary shafts are forced through the heat-processing coupling. As one or more rotary rubber rollers and combined rollers made of heat-resistant steel are sequentially installed and fixed by fixing nuts,

상기 회전고무롤러의 외주연으로는 세라본이 구성되고, 상기 내부회전체의 내부공간으로는 액체, 기체, 고체가 선택적으로 충진되어진다.The outer periphery of the rotary rubber roller is composed of a cerabon, and the interior space of the inner rotor is filled with liquid, gas, and solid selectively.

따라서, 상기와 같이 구성된 철강롤러는 다수개가 반복적으로 이송컨베이어에 설치되어 각각의 회전모터에 의해 회전하면서 무게하중이 매우 큰 철강제품 등 의 중량물을 이송하게 되는데, Therefore, the steel rollers configured as described above are repeatedly installed in the conveying conveyor to convey heavy objects such as steel products having a very high weight load while rotating by the respective rotating motors.

이때 상기 내부회전체 외주연에 다수개의 회전고무롤러가 설치되어져 있어, 중량물에 대한 충격을 흡수하여 줌과 동시에 내부회전체 내부에 충진된 액체, 기체, 고체 입자가 중량물의 진동과 소음을 이중으로 흡수하여 철강롤러의 고속회전시 발생하게 되는 진동과 소음을 보다 효과적으로 예방하여 주게 된다. At this time, a plurality of rotary rubber rollers are installed on the outer circumference of the inner rotor, absorbing the impact on the heavy object and at the same time, liquid, gas, solid particles filled inside the inner rotor double the vibration and noise of the heavy object Absorption effectively prevents vibration and noise generated during high speed rotation of steel rollers.

그러나, 위와 같은 종래의 철강롤러는 중량물의 이송시 그에 따른 소음이나 진동은 어느 정도 예방하여 줄 수 있으나, 단 시간내에 롤러에 편마모가 발생하거나 또는 철강롤러의 내부회전체 외주에 설치된 다수개의 회전고무롤러에 유격이 발생하여 흔들리거나 파손되는 등의 폐단을 가지고 있었다. However, the conventional steel rollers as described above can prevent the noise or vibration caused by the transfer of heavy materials to some extent, but a plurality of rotary rubbers installed on the outer circumference of the inner rotor of the steel roller or the occurrence of uneven wear on the roller within a short time The roller had a closed end such as play and shaking or breakage due to play.

이를 보다 상세히 설명하자면 상기의 철강롤러는 중량물을 회전고무롤러로 회전/이송시키는 것으로 중량물의 장시간 이송시, 상기 회전고무롤러 외주연의 세라본과 회전고무롤러가 중량물에 의해 쉽게 마모되거나 벗겨지는 문제가 발생함은 물론 제작이 바로 이루어진 철강제품은 고열을 가지고 있어, 상기 회전고무롤러와 그 외주연의 세라본이 쉽게 녹아 버리게 되는 폐단이 있었으므로 중량물의 이송에 불편함을 줌은 물론 소음 및 진동을 유발하였고, To describe this in more detail, the steel roller rotates / transfers the heavy material to the rotary rubber roller, and when the heavy material is transported for a long time, the slave rubber and the rotary rubber roller of the outer edge of the rotary rubber roller are easily worn or peeled off by the heavy material. Of course, the steel product is made immediately, as well as has a high temperature, the rotary rubber roller and its outer periphery had a closed end that is easily melted discomfort in transporting heavy materials, as well as noise and vibration Triggered,

나아가 종래의 철강롤러는 그 구성이 내부 액체,기체,고체를 저장할 수 있는 내부회전체와 상기 회전고무롤러와 세라본을 가지는 외부회전체로 구분 구성되어져 있어, 그 제조가 매우 까다로움은 물론 제조비용이 많이 소용되는 폐단을 가지고 있었던 실정이었다. Furthermore, the conventional steel roller is composed of an internal rotating body capable of storing internal liquids, gases, and solids, and an external rotating body having the rotary rubber roller and the serabon. It was a situation that had a costly use.

본 발명은 위와 같은 종래의 문제를 해소하여 주기 위하여 발명된 것으로서, 특히 철강롤러의 회전축 외주로 강선이 브러쉬 형상으로 감겨져 있는 하나 이상의 회전롤러를 반복설치하여 중량물의 진동과 소음을 상기 다량의 강선으로 흡수시켜 그 발생을 예방토록 하고 나아가 철강롤러의 구성을 보다 간소화시켜 그 제작과 비용의 절감효과를 얻을 수 있도록 하였다.
이하 첨부된 도면과 함께 본 발명을 상세히 설명하자면 아래와 같다. The present invention has been invented to solve the above conventional problems, in particular by repeating the installation of one or more rotary rollers in which the steel wire is wound in the shape of a brush around the outer shaft of the steel roller to the vibration and noise of the heavy weight to the large amount of steel wire Absorption to prevent its occurrence and further simplify the construction of the steel roller to achieve the effect of manufacturing and cost reduction.
Hereinafter, the present invention with reference to the accompanying drawings in detail.
