| By cutting-machining a side face of a scroll wrap with a non-rotational tool, swells in the perimeter direction have a smaller size. Thus, compressed gas is prevented from leaking between relatively slidable side faces of the respective wraps of the stationary scroll and the slewing scroll. This configuration provides a scroll compressor that has a higher accuracy and thus high compression efficiency and low noise are realized. | ||||||

| A performance of a compressor is enhanced and durability of scroll bodies is enhanced by optimizing relief to machining tolerance at a central end part of spiral members for forming the scroll bodies. In a scroll type compressor in which a reinforced portion (for example, a large radius of curvature R) reinforced more than in other root corner portions 5 is provided in a root corner portion 5 at a central end part in which a stress of the two spiral members 10 and 20 is increased, a first relief is formed in a region in which the two spiral members 10 and 20 come into contact with each other where the reinforced portion is applied only to one of the spiral members 10 and 20, and a second relief larger than the first relief is provided in a region in which the two spiral members come into contact with each other at a portion in which the radius of curvature R is provided in both of the two spiral members, thereby reasonably forming reliefs for avoiding interference at the point of contact of two spiral members. | ||||||

| A method of producing, in a workpiece such as a spiral member of a scroll element, a curved groove for receiving a mechanical seal by using a milling cutter, especially, an end mill. A relative feed in a given direction "A" is provided between the milling cutter and the work, and the milling cutter rotating in a predetermined direction "B" about an axis of rotation thereof is set so that the milling cutter provides an inner side wall of the curved groove with respect to a center of curvature of the curved groove with an up milling in which the direction "B" is directed against the direction "A", and that the milling cutter provides an outer side wall of the curved groove confronting the inner side wall with a down milling in which the direction "B" is directed toward the direction "A", in order to suppress formation of coarse and rough surface on both the inner and outer side wall of the curved groove. Thus, the width of the curved groove can be constantly accurate over an entire length of the groove. | ||||||

| A tool is brought into contact with a radially outer part of an inner wall surface of a scrollwall along an X-axis at a position displaced from the center of a basic circle of an involute curve by a radius of the basic circle along a Y-axis. Thereafter, the tool and the scrollwall are relatively moved along the X- and Y-axes while rotating the scrollwall about the center of the basic circle and keeping a normal direction of the wall surface at a contact point with the tool parallel with the X-axis, so that the tool is brought into contact with the wall surface from the same wall surface. In this way, the inner wall surface the wall surface at the center and the outer wall surface can be continuously processed in the same direction. The processing can be easily corrected based on a processing error resulting from the deviation of the positional relationship from a predetermined one, with the result that the processing accuracy can be maintained at a satisfactory level. | ||||||
| 96 | Scroll member and method of forming a scroll member | US778761 | 1991-10-21 | US5122040A | 1992-06-16 | Gene M. Fields |
| A scroll member is formed using a scroll profile cutter including a first portion generating a diameter equal to the desired width between scroll involute flanks, where the first portion also is of a length determined by a distance between the tip of the cutter and a second portion of greater diameter. The length of the first portion determines the scroll wrap height. Radii are provided at both ends of the first portion of the scroll profile cutter so that a fillet is generated at the base of the corresponding scroll wrap and a radius is generated at the edges of the scroll wrap tip to improve the strength of the scroll wrap and to remove sharp corners which could burr or interfere with the base of the opposing scroll wrap. | ||||||

| A scroll compressor has a pair of mating scrolls that are disposed on parallel, eccentric axes, and each of these scrolls has a scroll plate and a spiral, involute wrap. The scrolls are driven so that one of them orbits about the axis of the other scroll while maintaining a fixed azimuthal relationship to it. The orbital motion causes a compressible fluid to enter at the periphery of the scrolls, and be carried and compressed by pockets formed between the mating wraps of these scrolls. The compressed gas is discharged out a discharge port at the center of one of the scrolls. The discharge port is bored diagonally into the scroll plate of the one scroll so that it has an elongated elliptical aperture at the center of the scroll plate. The port is machined into the scroll from the wrap side of the scroll. The enlarged size of the port aperture reduces the resistance to fluid flow and hence reduces the back pressure, thereby increasing the compressor efficiency. | ||||||
