도 5는 공지된 스크롤 유체기계의 수직 측단면도이다.5 is a vertical side cross-sectional view of a known scroll fluid machine.

본 발명은 스크롤 유체기계에 관한 것이다.The present invention relates to a scroll fluid machine.

도 5는 공지된 스크롤 유체기계의 수직 측단면도이다.5 is a vertical side cross-sectional view of a known scroll fluid machine.

고정 스크롤(1)은 외주에 입구(2)를 가지고 중앙에 출구(3)를 가진 원형 고정 단부 플레이트(4)를 갖는다. 고정 단부 플레이트(4)는 전면에 나선 랩(spiral wrap)(5)을 갖고, 동일한 높이를 갖는 복수의 수평 물결모양 쿨링 핀(10)은 배면에 일정한 간격으로 배치된다.The fixed scroll 1 has a circular fixed end plate 4 with an inlet 2 on the outer circumference and an outlet 3 in the center. The fixed end plate 4 has a spiral wrap 5 on the front side, and a plurality of horizontal wavy cooling fins 10 having the same height are arranged at regular intervals on the back side.

고정 스크롤(1)의 뒤에 베어링 플레이트(11)가 제공된다. 베어링 플레이트(11)의 중앙에 있어서, 관형 보스(tubular boss)(15)는 베어링(14)을 통해 구동축(12)의 편심 축부(13)를 지지한다. 공지된 크랭크 핀형 자전 방지 장치(16)는 주변의 세 위치에 제공되고, 선회 스크롤(7)이 제공된 하우징(17)에 대하여 구동축(12) 주위로 선회 스크롤(7)이 선회하게 한다.The bearing plate 11 is provided behind the fixed scroll 1. In the center of the bearing plate 11, a tubular boss 15 supports the eccentric shaft portion 13 of the drive shaft 12 via the bearing 14. The known crankpin anti-rotation device 16 is provided in three peripheral positions, causing the pivoting scroll 7 to pivot about the drive shaft 12 with respect to the housing 17 provided with the pivoting scroll 7.

커버 플레이트(18)는 고정 스크롤(11)의 전면상에서 나사(19)로 고정된다. 선회 스크롤(7)은 베어링 플레이트(11)에 나사(20)로 고정된다. 고정 스크롤(1)의 배면(21)은 하우징(17)의 전면에 볼트(22)와 너트(23)로 고정된다.The cover plate 18 is fastened with screws 19 on the front surface of the fixed scroll 11. The swinging scroll 7 is fixed to the bearing plate 11 with a screw 20. The back 21 of the fixed scroll 1 is fixed to the front of the housing 17 with bolts 22 and nuts 23.

베어링 플레이트(11)의 배면상에 일정한 간격으로 배치된 자전 방지 장치(16)는 후방으로 개구되는 지지 튜브(24)와 맞물리는 종동부(25)와, 하우징(17)의 후벽(17a)에 일정한 간격으로 배치된 지지홀(20)과 맞물린 지지체(27)를 포함한다.The anti-rotation device 16 disposed on the rear surface of the bearing plate 11 at regular intervals is connected to the follower 25 which engages with the support tube 24 opened rearward, and the rear wall 17a of the housing 17. And a support 27 engaged with the support holes 20 disposed at regular intervals.

지지 튜브(24)의 개구단부는 지지 튜브(24)와 맞물리는 볼트(29)에 의해 고정된 베어링 홀더(28)와 접촉한다. 베어링 홀더(30)는 지지홀(26)의 전면과 접촉하고, 하우징(17)의 후벽(17a)과 맞물린 볼트(31)로 고정된다.The open end of the support tube 24 is in contact with a bearing holder 28 fixed by a bolt 29 that engages the support tube 24. The bearing holder 30 is in contact with the front surface of the support hole 26 and is fixed by a bolt 31 engaged with the rear wall 17a of the housing 17.

그러나, 하우징(17)의 후벽(17a)에 있어서의 자전 방지 장치(16)의 지지체(27)는 지지홀(26)과 맞물린다. 지지홀(26) 앞의 베어링 홀더(28)는 하우징(17)의 후벽(17a)에 볼트(31)로 고정된다.However, the support 27 of the anti-rotation device 16 in the rear wall 17a of the housing 17 is engaged with the support hole 26. The bearing holder 28 in front of the support hole 26 is fixed to the rear wall 17a of the housing 17 with bolts 31.

(a) 후벽은 하우징(17)의 전면 개구부로부터 멀리 떨어져 있다. 따라서, 하우징(17)의 후벽(17a)상에 자전 방지 장치(16)의 지지체(27) 전면과 접촉하는 베어링 홀더(30)를 지지하는 볼트(31)를 위한 암 보어(female bore)를 형성하기가 상당히 어렵다. 따라서, 볼트(31)를 위한 암 보어는 하우징(17) 후벽(17a)상의 커버 플레이트(32)의 볼트(33)를 위한 암 보어와 동일하다.(a) The rear wall is remote from the front opening of the housing 17. Thus, a female bore is formed on the rear wall 17a of the housing 17 for the bolt 31 supporting the bearing holder 30 in contact with the front surface of the support 27 of the anti-rotation device 16. It is quite difficult to do. Thus, the arm bore for the bolt 31 is identical to the arm bore for the bolt 33 of the cover plate 32 on the rear wall 17a of the housing 17.

그러나, 볼트(31)와 그 툴은 하우징(17)의 전면 개구부로부터 암 보어에 놓여 하우징(17)의 전면으로부터 먼 후벽(17a)의 암 보어를 볼트(31)가 통과하도록 하여 상당히 힘들고 많은 시간이 소요된다.However, the bolt 31 and its tool are placed in the arm bore from the front opening of the housing 17 and allow the bolt 31 to pass through the arm bore of the rear wall 17a away from the front of the housing 17, which is quite difficult and time consuming. This takes

(b) 하나의 베어링 홀더(30)를 위한 3개 이상의 볼트(31)가 존재하여 볼트(31)가 고정밀도로 평행하고 일정하게 암 보어와 맞물리기가 어렵게 한다. 베어링 홀더(30)의 중앙이 자전 방지 장치(16)의 지지체(27)의 축으로부터 이격되거나 베어링 홀더(30)가 하우징(17)의 후벽(17a)의 전면에 대하여 기울어지기 쉽다. 따라서, 베어링 홀더(30)의 전체 표면은 지지홀(26)의 에지와 일정하게 가압되어 접촉하지 않는다. 따라서, 지지체(27)와 종동부(25)의 연결부뿐만 아니라 베어링의 다른 관련 부품에 있어서 부하가 일정해지지 않아서 관련 부품의 마모를 촉진시킨다.(b) Three or more bolts 31 for one bearing holder 30 are present, making it difficult for the bolts 31 to mesh with the arm bores with high accuracy and parallelism. The center of the bearing holder 30 is spaced apart from the axis of the support 27 of the anti-rotation device 16 or the bearing holder 30 is inclined with respect to the front surface of the rear wall 17a of the housing 17. Therefore, the entire surface of the bearing holder 30 is not pressed in constant contact with the edge of the support hole 26. Thus, the load is not constant at the connection of the support 27 and the follower 25 as well as other related parts of the bearing to promote wear of the related parts.

(c) 사용함에 따라, 진동, 열에 의한 팽창/수축 및 다른 원인이 볼트(31)를 느슨하게 함으로써 하우징(17)의 후벽(17a)에 있어서의 자전 방지 장치(16)의 지지체(27)를 유지하도록 베어링 홀더(30)를 충분히 가압하지 못하게 한다.(c) With use, the support 27 of the anti-rotation device 16 in the rear wall 17a of the housing 17 may be held by loosening the bolt 31 due to vibration, heat expansion / contraction and other causes. The bearing holder 30 may not be sufficiently pressurized.

(d) 베어링 홀더(30) 장착의 전후에 있어서, 자전 방지 장치(16)의 지지 체(27)를 축방향으로 조정 또는 변경하는 것을 거의 불가능하게 한다.(d) Before and after mounting the bearing holder 30, it becomes almost impossible to adjust or change the support body 27 of the anti-rotation device 16 in the axial direction.

(e) 베어링 홀더(30)는 제조 및 유지보수를 어렵게 하는 분리된 부재로서 제조되어야 한다.(e) The bearing holder 30 should be manufactured as a separate member that makes manufacturing and maintenance difficult.

상기 문제점을 감안하여 이루어진 것으로서, 본 발명의 목적은 하우징의 후벽에 자전 방지 장치의 지지체를 유지하는 것을 용이하게 함으로써 지지체에 베어링 홀더를 일정하고 정확하게 장착할 때의 어려움및 수고를 극복하게 하는 스크롤 유체기계를 제공하는 것이다.In view of the above problems, an object of the present invention is to facilitate the maintenance of the support of the anti-rotation device on the rear wall of the housing, thereby overcoming the difficulties and troubles of constantly and accurately mounting the bearing holder on the support. To provide a machine.
