Scroll fluid machine

Co-rotational scroll apparatus with optimized coupling between scroll wraps.

In a co-rotational scroll apparatus having two interleaving scroll wraps secured to end plates rotating about parallel, non-concentric axes to produce a relative orbital motion, a coupling for causing concurrent rotation and for enhancing the nutational stability of the scroll element. In the preferred embodiment, the nutation reducing means is comprised of an Oldham-type coupling engaging extension members on one of the scroll end plates and drive keys on the other respective end plate. The angular disposition thereof is optimized to cause the Oldham coupling to generate during rotation a moderating moment load in opposition to the tipping moment load of at least one of the scroll elements and thereby enhance the nutational stability of the scroll elements. The moderating moment load of the coupling imposed on the scroll elements may be altered by varying the angular and radial disposition of the center of gravity of the coupling.

Scroll compressor

An orbiting scroll 2 meshes with a non-orbital scroll 1 to form a compression space. A frame 3 axially supports the orbiting scroll and radially supports a drive shaft 8. A high and low pressure separator 4 is fixed to the frame 3. A seal member 10 in a clearance between the separator 4 and the non-orbital scroll 1 defines a pressure portion which presses the scroll 1 toward the scroll 2. The seal member 10 is disposed in the clearance at a position so as to lie in a plane parallel with the base plate of the non-orbital scroll 1 so that the scroll 1 is not diametrically restrained at the seal position.

MANUFACTURE OF OLDHAM'S COUPLING IN SCROLL COMPRESSOR

PURPOSE: To manufacture Oldham's couplings in quantities by manufacturing an annular plate and pawl members that constitute an Oldham's coupling separately and fixing the pawl members to the annular member by stud welding or air resistance welding. CONSTITUTION: A thin steel plate is blanked by press working and a thin annular member 91 is manufactured. On the other hand pawl members 92 are worked by a milling machine up to finishing. Then, pawl members 92 for fitting bearing and fitting oscillating scroll are fixed to the member 91 by stud welding or air resistance welding such as projection welding. In stud welding or air resistance welding, current is let flow to the members 91, 92, and an arc is generated only between the joint planes to cause local melting. Accordingly, distortion due to heating hardly occurs in the members 91, 92, and additional working after welding is not required. Thus, Oldham's couplings suitable for mass production can be obtained. COPYRIGHT: (C)1983,JPO&Japio ...

스크롤 압축기는 선회스크롤을 붙잡기 위한 자전(自轉)방지장치로서 소결금속으로 만든 올댐링(Oldhams ring)을 구비하고 있다. 그리고 올댐링은 소결금속성형의 후속공정인 절삭작업이나 연삭작업에 맞게 모양을 갖춤으로써 결과적으로 올댐링의 생산성이 개선되며 내마모성이 우수하게 된다. 그리고 내마모성이 우수한 경(硬)소결합금을 채용하여 싸고 신뢰도가 높은 스크롤 압축기를 얻을 수 있다. 제1홈(3a)과 제2홈(3b)은 올댐링의 환상(環狀)링(2)의 끝면(end face)(3)에 형성되어 소결된다. 그리고 올댐링의 제조후 높이는 제1홈(3a)이 가장 낮고, 다음 제2홈(3b), 그리고 끝면(3)의 순이다. 공구에서 가장 마모되기 쉬운 모서리부분은 가공부담이 상당량 줄어들고 주로 공구의 측면(side face)에 의해서 가공된다. 그리고 제1홈(3a)부분을 가공하지 않으므로 결국 공구의 비용이 절감된다. The scroll compressor has an Oldhams ring made of sintered metal as an anti-rotation device for catching the turning scroll. In addition, the old dam ring is shaped for cutting or grinding work, which is a subsequent process of sintering metal forming, and as a result, productivity of the old dam ring is improved and wear resistance is excellent. In addition, by employing a light alloy having excellent wear resistance, a scroll compressor having low cost and high reliability can be obtained. The first groove 3a and the second groove 3b are formed on the end face 3 of the annular ring 2 of the old dam ring and sintered. And the height after the manufacture of the old dam ring is the lowest in the first groove (3a), the next second groove (3b), and the end surface (3). The edges most prone to wear on the tool are significantly reduced in machining burden and are mainly machined by the side face of the tool. In addition, since the first groove 3a is not processed, the cost of the tool is reduced.
