Description

탈착이 가능한 씰투스를 갖는 틸팅패드 저어널 베어링.{Tilting pad journal bearing with removal seal tooth.}Tilting pad journal bearing with removal seal tooth.

본 발명은 베어링케이스턱의 내주연 원주방향으로 가공 형성된 홈부와, 상기 홈부에 안착되는 씰투스와, 베어링케이스의 측면에서 관통되어 상기 홈부내에 형성된 결합공이 다수개로 형성되고, 상기 결합공에 정확하게 일치되도록 나사산을 가진 관통공이 형성된 씰투스를 볼트로 체결하여 베어링케이스에서 씰투스를 탈착가능하게 하여 베어링케이스에 씰투스의 교체 및 설치에 소요되는 시간을 절약하고 가공에 소요되는 비용을 절감토록한 탈착이 가능한 씰투스를 갖는 틸팅패드 저어널베어링에 관한 것이다.The present invention is formed with a plurality of grooves formed in the inner circumferential direction of the bearing case jaw, a seal tooth seated on the groove portion, and a plurality of coupling holes formed in the groove portion through the side of the bearing case, and accurately formed in the coupling holes. Tighten the seal tooth with threaded through-hole to be matched with bolts so that the seal tooth can be detached from the bearing case, saving time for replacement and installation of the seal tooth in the bearing case and reducing the cost of processing. The present invention relates to a tilting pad journal bearing having a detachable seal tooth.

일반적으로 틸팅패드 저어널베어링은 도 1에 도시된 바와 같이 윤활유는 외부에서 환상홈(annulus groove)(504)을 통해 공급되면 공급홀(feed hole)(503)을 지나 오리피스(501)를 통과한 후 베어링패드(202)로 공급되는 구조를 가지고 있다.In general, as the tilting pad journal bearing is shown in FIG. 1, when lubricating oil is supplied through an annular groove 504 from the outside, the lubricating oil passes through a feed hole 503 and passes through an orifice 501. The bearing pad 202 is then supplied to the structure.

축이 회전하게 되면 윤활유는 베어링패드(202)의 선단으로 유입하여 베어링패드(202)의 후단으로 빠져나게 되고 회전하는 로터와 마찰로 인하여 윤활유 온도는 상승하게 된다.When the shaft rotates, the lubricating oil flows into the front end of the bearing pad 202 and exits to the rear end of the bearing pad 202. The lubricating oil temperature is increased due to friction with the rotating rotor.

따라서, 오피리스(501)로부터 냉각된 윤활유와 혼합되므로, 베어링패드(202)선단으로 공급되는 전체적 윤활유의 온도는 오피리스(501)에서 공급되는 윤활유의 온도보다 높게된다.Therefore, since it is mixed with the lubricating oil cooled from the opiris 501, the temperature of the overall lubricating oil supplied to the tip of the bearing pad 202 becomes higher than the temperature of the lubricating oil supplied from the opis 501.

한편, 틸팅패드 저어널베어링에 설치된 씰투스(203)는 도 2 및 도 3에 도시된 바와 같이, 씰투스(203)는 베어링 케이스(200)의 양 끝단 턱에 형성하여 로터(201)와 베어링패드(202)사이에서 유막(윤활유막)을 형성하고 있는 윤활유가 축방향으로 과도하게 배출되는 것을 막고, 베어링 운전중 로터(201)와 베어링패드(202)사이에 적정한 유막(윤활유막)이 유지되는 것을 돕도록 구성한다.Meanwhile, as shown in FIGS. 2 and 3, the seal tooth 203 installed in the tilting pad journal bearing is formed on the jaws of both ends of the bearing case 200 to form the rotor 201 and the bearing. Prevents excessive discharge of lubricating oil which forms an oil film (lubricating oil film) between the pads 202 in the axial direction, and maintains an appropriate oil film (lubricating oil film) between the rotor 201 and the bearing pad 202 during bearing operation. Organize to help

이와 같은 씰투스(203)는 기존의 틸팅패드 저어널베어링에 있어, 윤활유가 과도하게 누설되는 것을 방지하기 위한 목적으로 설치하며 씰투스(203)를 고정하기 위해서는 코킹(calking)작업을 한다.Such seal tooth 203 is installed in the existing tilting pad journal bearing for the purpose of preventing excessive leakage of lubricating oil and caulking (calking) to fix the seal tooth 203.

또한, 베어링 설계자는 씰투스(203)가 마모되거나 씰투스(203)의 높이가 변경되어 씰투스(203)를 재설치할 경우, 베어링을 외부로 반출한 후, 기존에 설치된 씰투스(203)를 제거하기 위하여 베어링케이스턱(204)에 홈부(205)를 가공한 후, 상기 홈부(205)에 씰투스(203)를 안착시키고, 이를 고정하기 위해여 코킹(calking)작업을 한 후, 설계 치수대로 정삭하는 작업을 수행하여야 한다. In addition, when the seal tooth 203 is worn out or the height of the seal tooth 203 is changed and the seal tooth 203 is reinstalled, the bearing designer takes out the existing seal tooth 203 after carrying out the bearing to the outside. After removing the groove 205 in the bearing case jaw 204 to remove it, the seal tooth 203 is seated in the groove 205, and then caulked to fix it. Finishing work should be carried out.

이 경우, 씰투스(203)의 제작과 설치에 많은 시간이 소요되고 베어링케이스(200)를 가공기계가 있는 장소까지 이송하는데 따른 시간적 경제적 손실을 준 많은 문제점이 있었다.In this case, the production and installation of the seal tooth 203 takes a lot of time, and there are many problems that give a time and economic loss of transporting the bearing case 200 to the place where the processing machine is located.

상기와 같은 문제점을 해결하기 위해서, 본 발명은 베어링케이스턱의 내주연 원주방향으로 가공 형성된 홈부와, 상기 홈부에 안착되는 씰투스와, 베어링케이스의 측면에서 관통되어 상기 홈부내에 형성된 결합공이 다수개로 형성되고, 상기 결합공에 정확하게 일치되도록 나사산을 가진 관통공이 형성된 씰투스를 볼트로 체결하여 베어링케이스에서 씰투스를 탈착가능하게 하여 베어링케이스에 씰투스의 교체 및 설치에 소요되는 시간을 절약하고 가공에 소요되는 비용을 절감하기 위하여 탈착이 가능한 씰투스를 갖는 틸팅패드 저어널베어링을 제공하는 데 그 목적이 있다.In order to solve the above problems, the present invention provides a plurality of grooves formed in the inner circumferential direction of the bearing case jaw, a seal tooth seated on the groove portion, and a plurality of coupling holes formed in the groove portion through the side of the bearing case. It is formed of two pieces, and the seal tooth formed with the threaded through-hole to be exactly matched to the coupling hole is bolted so that the seal tooth is detachable from the bearing case, thereby saving time for replacing and installing the seal tooth in the bearing case. The purpose is to provide a tilting pad journal bearing having a detachable seal tooth in order to reduce the cost of processing.
