본 발명은 베어링에 관한 것으로, 특히 내경외륜을 N극 외경내륜을 N극으로 착자시켜 무접촉 상태에서 회전하도록 하여 소음이 적을 뿐만 아니라, 제조가 간편하며 가격이 저렴하면서 마모와 파손등이 없도록 한 볼레스베어링에 관한 것이다.The present invention relates to a bearing, and in particular, the inner diameter outer ring is magnetized to the N pole outer diameter inner ring to the N pole to rotate in a non-contact state, so that the noise is not only low, but also easy to manufacture and inexpensive so that there is no wear and damage It is about a ballless bearing.

종래 기술에 따른 볼베어링은 도 2에 도시되어 있는바, 회전축이 삽입되는 내경면에 있는 내륜(10)과, 이 내륜(10)의 외측이면서 도시되지 않은 하우징에 고정되는 외경면의 외륜(11)과, 상기 내륜(10)과 외륜(11)의 사이에서 회전하도록 설 치된 볼(13)과, 이 볼(13)을 리벳(14)으로 감싸도록 한 리테이너(15)와, 상기 내륜(10)과 외륜(11)의 사이에 배치된 볼(13)로 수분이 침투되지 않도록 설치된 시일드(16)를 포함한다.The ball bearing according to the prior art is shown in Fig. 2, the inner ring 10 in the inner diameter surface into which the rotating shaft is inserted, and the outer ring 11 of the outer diameter surface which is fixed to a housing not shown and outside of the inner ring 10. And a ball 13 installed to rotate between the inner ring 10 and the outer ring 11, a retainer 15 for wrapping the ball 13 with a rivet 14, and the inner ring 10. And a shield 16 installed so that moisture does not penetrate into the ball 13 disposed between the outer ring 11 and the outer ring 11.

따라서 도시되지 않은 회전축이 회전하게 되면 회전축과 고정된 내륜(10)의 외경과 도시되지 않은 하우징에 고정된 외륜(11)의 내경에 배치된 볼(13)이 회전하게 된다.Therefore, when the rotating shaft (not shown) rotates, the ball 13 disposed at the outer diameter of the inner ring 10 fixed to the rotating shaft and the inner diameter of the outer ring 11 fixed to the housing not shown rotates.

그러나 상기 볼(13)에 의해 원활히 회전을 하는 경우 소음등을 일으키지 않기 위해서는 볼의 정밀도와 궤도면인 외륜의 내경과 내륜의 외경을 정밀하게 가공해야 하는 문제점이 있었다.However, when the ball 13 rotates smoothly, there is a problem in that the precision of the ball and the inner diameter of the outer ring and the inner diameter of the inner ring are processed precisely so as not to generate noise.

또한 이들 중요 부품의 조그만 결함이 있을 때에는 당장 소음에 문제가 발생되는 문제점이 있었다.In addition, when there are small defects of these important parts, there was a problem that a problem occurs immediately.

또 생산에 따른 공정이 많고, 가격 또한 고가인 문제점이 있었다.In addition, there are many processes involved in production, and the price is also expensive.

이에 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 내경외륜을 N극 또 외경내륜을 N극으로 착자시켜 무접촉 상태에서 회전하도록 구성하여, 소음이 적을 뿐만 아니라 제조가 간편하며 가격이 저렴하면서 마모와 파손등이 없도록 한 볼레스베어링를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by rotating the inner diameter outer ring to the N pole and the outer diameter inner ring to the N pole to rotate in a non-contact state, not only low noise but also easy to manufacture and cost Its purpose is to provide a ballless bearing that is inexpensive and free of wear and tear.

상기와 같은 목적을 달성하기 위한 본 발명은, 회전축의 회전이 자유롭게 이루어지도록 설치되는 볼레스베어링에 있어서, 상기 회전축이 중심에 끼워지면서 외경의 양단에는 제1 단차부가 형성된 내륜과, 상기 내륜의 일측 제1 단차부에 맞춰져 회전되도록 내경의 일단에 돌출부가 형성됨과 더불어 타단의 외경에는 제2 단차부가 형성된 외륜과, 상기 외륜의 제2 단차부에 압입되어 안착됨과 더불어 상기 내륜의 타측 제1 단차부에 맞춰져 고정된 측면코어를 갖추는 한편, 상기 내륜의 외경부 전체와 상기 외륜의 내경부 전체에는 같은 극성을 갖도록 착자되며, 상기 측면코어의 내경에 내륜의 외경과 같은 극성으로 착자된 것을 특징으로 하는 볼레스베어링을 제공한다.The present invention for achieving the above object is, in a ballless bearing installed so that the rotation of the rotation shaft is free, the inner ring is formed in the first step portion at both ends of the outer diameter while the rotation shaft is fitted in the center, and one side of the inner ring A protruding portion is formed at one end of the inner diameter so as to be rotated in accordance with the first step portion, and an outer ring having a second step portion is formed at the outer diameter of the other end, and is press-fitted and seated on a second step portion of the outer ring, and the other first step portion of the inner ring While having a side core fixed in accordance with, while the entire outer diameter portion of the inner ring and the entire inner diameter portion of the outer ring magnetized to have the same polarity, the inner diameter of the side core is magnetized with the same polarity as the outer diameter of the inner ring Provides ballless bearings.

이하 본 발명에 의한 일실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 볼레스베어링을 설명하는 종단면도이다.1 is a longitudinal cross-sectional view illustrating a ballless bearing according to the present invention.

본 발명에 따른 볼레스베어링(100)은, 도시되지 않은 회전축이 중심에 끼워지면서 외경의 양단에는 제1 단차부(111)가 형성되면서 외륜에는 N극이 착자되도록 한 내륜(110)과, 이 내륜(110)의 일측 제1 단차부(111)에 맞춰지도록 내경의 일단에 돌출부(121)가 형성됨과 더불어 타단의 외경에는 제2 단차부(122)가 형성되면서 내경에는 N극이 외경에는 S극이 착자되도록 한 외륜(120)를 포함한다.The ballless bearing 100 according to the present invention includes an inner ring 110 having a first stepped portion 111 formed at both ends of an outer diameter while the rotating shaft (not shown) is fitted at the center thereof, and the N pole is magnetized at the outer ring. The protrusion 121 is formed at one end of the inner diameter to be aligned with the first stepped portion 111 of the inner ring 110, and the second step 122 is formed at the outer diameter of the other end, while the N pole is S at the outer diameter. It includes an outer ring 120 to allow the pole to magnetize.

물론 상기 내륜(110)과 외륜(120)의 극성이 같은 경우에는 S극이 착자되어도 무방하다.Of course, when the inner ring 110 and the outer ring 120 have the same polarity, the S pole may be magnetized.

또한 상기 외륜(120)의 제2 단차부(122)에 압입되어 안착됨과 더불어 상기 내륜(110)의 타측 제1 단차부(111)에 맞춰져 고정된 단면이 ㄱ자 형상으로 이루어진 측면코어(130)를 포함한다.In addition, the side core 130 is press-fitted to the second step portion 122 of the outer ring 120 and the cross-section fixed to the other first step portion 111 of the inner ring 110 has a L-shape. Include.

여기서 상기 측면코어(130)는 내경측이 N극 외경측이 S극으로 착자되어 있 다.Here, the side core 130 is magnetized to the inner pole side of the N pole outer diameter side S pole.

또 상기 내륜(110)과 외륜(120)은 일정한 간격을 유지하도록 조립되어 있다.In addition, the inner ring 110 and outer ring 120 is assembled to maintain a constant interval.

따라서 상기 외륜(120)은 도시되지 않은 하우징에 압입하여 설치하고, 상기 회전축에 압입되어 설치된 내륜(110)을 외륜(120)의 내경측으로 끼운 다음, 상기 측면코어(130)를 상기 외륜(120)의 제2 단차부(122)에 압입하여 볼레스 베어링의 설치를 완료한다.Therefore, the outer ring 120 is press-installed in a housing (not shown), and the inner ring 110 is pressed into the rotation shaft and inserted into the inner diameter side of the outer ring 120, and then the side core 130 is the outer ring 120 The second stepped portion 122 is pressed in to complete the installation of the ballless bearing.

이때 상기 내륜(110)의 외경과 외륜(120) 및 측면코어(130)의 내경이 모두 N극으로 착자되어 있어 회전축이 회전할 때 상기 내륜(110)과 외륜(120)은 아무런 접촉이 없이 회전이 된다.At this time, both the outer diameter of the inner ring 110 and the inner diameter of the outer ring 120 and the side core 130 are magnetized to the N pole so that the inner ring 110 and the outer ring 120 rotates without any contact when the rotating shaft rotates. Becomes

즉, 상기 내륜(110)과 외륜(120)은 무접촉에 의해 회전되므로 소음이 없게 된다.That is, the inner ring 110 and the outer ring 120 is rotated by contactless, there is no noise.

또한 상기 내륜(110)과 외륜(120) 및 측면코어(130)는 별도의 볼이 삽입되지 않으므로 조립공정의 단순화는 물론 원가절감이 이루어진다.In addition, since the inner ring 110, the outer ring 120 and the side core 130 are not inserted into a separate ball, the assembly process is simplified as well as cost reduction.

이상 설명한 바와 같이 본 발명에 의하면, 소음이 적을 뿐만 아니라 제조가 간편하며 가격이 저렴하면서 마모와 파손등이 없는 효과가 있다.As described above, according to the present invention, not only the noise is low, but the manufacturing is simple and the price is low, and there is no effect of wear and damage.
