본 고안은 모우터축을 지지하는 베아링장치에 관한 것으로, 비교적 작은 하중이나 주속(周速)조건(축의 비틀림에 의하여 베아링에 접촉하는 국부접촉면등)이 발생하는 곳에 이용되는 소형 모우터축을 지지하는 개량된 베아링장치에 관한 것이다.The present invention relates to a bearing device for supporting a motor shaft, and an improvement for supporting a small motor shaft used in a place where a relatively small load or circumferential condition (local contact surface contacting the bearing due to the torsion of the shaft) occurs. It relates to a bearing device.
일반적으로 모우터축을 지지하는 베아링장치는 상기 모우터축을 확실하게 지지하고 원활한 축의 회전을 위하여 베아링장치의 성능이 보다 우수하게 설치한 바가 있으며, 따라서 베아링 구조의 내하중성을 향상시켜서 전체적인 베아링 장치의 수명을 연장시킴과 동시에 신뢰성을 높이는 것이 바람직하며 또한 축을 지지하는 베아링 구조의 간단함도 요청되어 왔었다.In general, the bearing device for supporting the motor shaft has been installed with better performance of the bearing device in order to reliably support the motor shaft and smooth rotation of the shaft, thus improving the load resistance of the bearing structure to improve the life of the overall bearing device. It is desirable to increase the reliability and to increase the reliability, and the simplicity of the bearing structure supporting the shaft has also been requested.
종래에는 축에 베아링을 지지시키기 위하여 축과 접하여 일체로 회전하는 내륜에 베아링을 장착시킨 뒤 상기 베아링에 다시 외륜을 감싸 하우징에 설치한 구조로 되어 있었다.Conventionally, in order to support the bearing on the shaft, the bearing was mounted on the inner ring which is integrally rotated in contact with the shaft, and then the outer ring was wrapped around the bearing to be installed in the housing.
이와 같은 구조로 인하여 축이 회전할 때 상기 축과 하우징에 장착된 부착면과 같은 내ㆍ외륜이 움직이므로 베아링의 회전을 저지시킬 뿐만 아나라, 축에 베아링 내경을 강제 압입하므로 볼 베아링의 볼 파손으로 베아링의 불량을 야기시켜 회전기기의 고장을 일으킬 염려가 있었다.Due to this structure, when the shaft rotates, the inner and outer rings, such as the mounting surface mounted on the shaft and the housing, move, which not only prevents the rotation of the bearing, but also forcefully presses the bearing inner diameter into the shaft. As a result, there was a fear of causing a failure of the bearing by causing a failure of the bearing.
이에 본 고안은 상기한 결점을 해소시키기 위하여 하우징에 베아링 외경을 강제 압착시켜 고정시키고 축에 내륜을 설치하되 상기 내륜의 안쪽끝에다 판 스프링과 E링을 설치하며, 상기 내ㆍ외륜사이에 베아링을 장착하므로 축이 회전할 때 축에 일체로 부착된 내륜을 효과적으로 지지할 뿐만 아니라 내륜에 설치된 판스프링에 베아링의 하중이 일정하게 분배되어 회전기기의 원활한 회전을 유도하는 모우터축을 지지하는 베아링장치를 제공함에 그 목적이 있다.In order to solve the above-mentioned shortcomings, the present invention forcibly compresses and fixes the bearing outer diameter on the housing and installs an inner ring on the shaft, and installs a leaf spring and an E ring at the inner end of the inner ring, and installs the bearing between the inner and outer rings. As the shaft rotates, it not only effectively supports the inner ring that is integrally attached to the shaft, but also the bearing device that supports the motor shaft that induces the smooth rotation of the rotating machine by uniformly distributing the load of the bearing to the leaf spring installed on the inner ring. The purpose is to provide.
이하, 본 고안은 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail based on the accompanying drawings.
본 고안은 외륜(1)의 면이 접하는 하우징(2)의 선단 안쪽둘레면에 지지부(3)를 형성시키고 상기 하우징(2)에 외륜(1)을 설치하되 상기 외륜(1)의 안쪽끝에다 탄발력을 갖춘 판스프링(4) 및 E링(5)을 장착하여 외륜(1)을 지지하며, 내륜(6)사이에 축(7)을 내장시킨 구조로 되어 있다.The present invention forms a support part 3 on the inner circumferential surface of the front end of the housing 2 in contact with the surface of the outer ring 1 and installs the outer ring 1 on the housing 2, but at the inner end of the outer ring 1. The leaf spring 4 and the E-ring 5 having elasticity are mounted to support the outer ring 1, and the shaft 7 is embedded between the inner rings 6.
미설명부호 8은 회전기기, 9는 베아링 볼이다.Reference numeral 8 is a rotary machine, 9 is a bearing ball.
제1도 및 제2도는 본 고안은 일례로 선풍기 모우터축에 설치한 전체적인 단면도를 도시한 것으로, 종래의 내륜을 축에 압입하여 고정하던 베아링구조를 본 고안에서는 도시된 바와 같이 하우징(2)에 외륜(1)을 강제 압입하되 상기 외륜(1)의 한쪽끝에다 탄발력을 갖춘 판스프링(4)을 장착시키고, 그 판스프링(4)의 다른쪽면은 상기 축(7)에 설치된 E링(5)과 접하도록 한다. 또한 하우징(2)에는 그 선단 안쪽둘레면에 상기 외륜(1)의 면을 지지하여 외부로 빠져나오지 못하게 하는 지지부(3)를 형성하므로서, 외륜(1)의 면은 그 지지부(3)에 접하여 하우징(2)에 압착고정되어 있고, 또한 내륜(6) 사이에다 축(7)을 설치한다.1 and 2 show the overall sectional view of the present invention installed in the fan motor shaft as an example. In the present invention, a bearing structure in which a conventional inner ring is press-fitted to the shaft is fixed to the housing 2 as shown in the present invention. The outer ring 1 is forcedly press-fitted to one end of the outer ring 1, and a leaf spring 4 having elastic force is mounted, and the other side of the leaf spring 4 has an E ring installed on the shaft 7 5). In addition, the housing 2 is formed with a support part 3 on the inner circumferential surface of the tip thereof to support the surface of the outer ring 1 so as not to escape to the outside, so that the surface of the outer ring 1 is in contact with the support part 3. It is fixed to the housing 2 and the shaft 7 is provided between the inner rings 6.
이와 같이 이루어진 베아링장치는 축(7)이 모우터의 회전기기(8)에 의하여 회전할 때, 상기 축(7)에 일체로 부착된 내륜(6)은 처음에 안쪽으로 약간 뒤로 밀린 후 인장력을 부여하는 판스프링(4)의 탄발력에 의해 다시 원래의 위치로 내륜(6)을 밀므로 축(7)과 함께 회전하게 된다.The bearing device made in this way has a tension force when the shaft 7 is rotated by the rotary machine 8 of the motor, and the inner ring 6 integrally attached to the shaft 7 is initially pushed back slightly inward. The inner ring 6 is pushed back to its original position by the elastic force of the leaf spring 4 to be imparted, thereby rotating together with the shaft 7.
또한 상기 내륜(6)과 접하는 베아링볼(9)이 상기 축(7)과 함께 회전할 때 베아링볼(9)의 하중을 상기 내륜(6)에 균등하게 분배되어질 수 있도록, 상기 판스프링(4)은 축(7)에 고정된 E링(5)을 고정점으로 약간의 전후이동이 가능하다. 더욱, 하우징(2)에 압착고정된 외륜(1)은 상기 하우징(2) 선단 안쪽 둘레면에 형성된 지지부(3)에 의해 확실히 고정될 뿐만 아니라 축(7)이 회전하더라도 좌우이동이 적어진다.In addition, the leaf spring 4 so that the load of the bearing ball 9 can be evenly distributed to the inner ring 6 when the bearing ball 9 in contact with the inner ring 6 rotates with the shaft 7. ) Can be moved back and forth slightly with the E-ring (5) fixed to the shaft (7) as a fixed point. In addition, the outer ring 1 which is pressed and fixed to the housing 2 is not only securely fixed by the support part 3 formed on the inner circumferential surface of the front end of the housing 2 but also less lateral movement even if the shaft 7 rotates.
이상과 같이 이루어진 본 고안은 외륜(1)과 접하는 하우징(2)에 지지부(3)를 형성시키고 내륜(6)을 축(7)에 부착하되, 축(7)에 고정된 E링(5)에 판스프링(4)이 접하여 상기 내륜(6)을 받쳐주게 되므로써 축에 일체로 부착된 내륜과 하우징에 부착된 외륜은 상기 축이 회전하더라도 좌우이동을 효과적으로 방지하고 베아링의 회전하중을 판스프링의 인장력을 적절하게 내륜에 분배시켜 회전기기의 원활한 회전을 유도할 수 있는 잇점이 있다.The present invention made as described above forms a support part 3 in the housing 2 in contact with the outer ring 1 and attaches the inner ring 6 to the shaft 7, but the E ring 5 fixed to the shaft 7. Since the leaf spring 4 is in contact with the inner ring 6 to support the inner ring 6, the inner ring integrally attached to the shaft and the outer ring attached to the housing effectively prevent left and right movement even if the shaft rotates, and prevent the rotation load of the bearing from the leaf spring. The advantage is that the tension can be properly distributed to the inner ring to induce smooth rotation of the rotating machine.
