| 61 | Scroll-type compressor, scroll, and manufacturing method with partially abbreviated machine working process | US10047590 | 2002-01-15 | US20020098100A1 | 2002-07-25 | Tatsushi Mori; Masao Iguchi; Yasushi Watanabe; Yoshio Fujita; Shinsuke Asou; Yoshiharu Yoshida |
| A scroll material 160 for the production of a scroll is cast, a scroll portion 54 thereof is left as cast, and the portions other than the scroll portion 54 are machine-worked. Positioning portions 168, 169, and 170 and an engagement hole 172 are cast together with the scroll portion 54 of the scroll material 160, etc., in a die-casting process. In a machine working process, an engagement portion 248 of a holding jaw 234 is engaged with the engagement hole 172 of the positioning portion 168 and at the same time the positioning portions 168, 169, and 170 are held with the holding jaws 234, 236 and 238 of a chuck 230. In this state, the outer side surface of the base 162 opposite to the scroll portion 54, etc., are cutting-worked with work tools. Using the positioning portions 168, 169, and 170 as the work basis is almost equal to using the scroll portion 54 as the work basis, and a movable scroll, having a high relative positioning accuracy between the scroll portion 54 and other portions, can be manufactured. | ||||||
| 62 | Variable flank relief for scroll wraps | US238383 | 1999-01-27 | US6149411A | 2000-11-21 | James W. Bush |
| A scroll compressor having a non-uniform generating radius for its scroll wraps is formed to have a flank relief which is greatest at locations having the highest generating radius. In scroll compressors having non-uniform generating radii, there is an increased likelihood of contact at the areas having the highest generating radius. Thus, flank relief is provided at the areas having the higher generating radii. In addition, the flank relief is preferably proportional to the generating radius. Further at areas having a generating radius below a predetermined minimum, no flank relief is necessary. | ||||||
| 63 | Method of manufacturing a movable scroll element and a scroll element produced by the same method | US677955 | 1996-07-10 | US5711659A | 1998-01-27 | Tetsuhiko Fukanuma; Yasushi Watanabe; Shinya Yamamoto; Yuichi Tsumagari; Shigeki Iwanami |
| A movable scroll element for a scroll type compressor is produced by a combination of a mold casting process and a machining process. The mold casting process produces a cast product having an end-plate forming portion, a spiral-member-forming portion and a projecting portion for forming a drive power receiving portion. The cast product has an entire outer faces covered with black scale, and the machining process machines the end-plate-forming portion, a spiral member forming portion, the projecting portion by cutting. Nevertheless, at least an outer circumference of the drive power receiving portion, i.e., a boss portion of the movable scroll element is covered with an outermost layer consisting of black scale. Thus, a sufficient mechanical strength of the movable scroll element is obtained even if the wall thickness of the drive power receiving portion, i.e., the boss portion of the movable scroll element, is reduced. | ||||||

| 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. | ||||||

| Disclosed is a method of working a semi-finished scroll member for a scroll compressor which has a circular end plate having a first end face and a second end face with a spiral wrap extending therefrom. Before the second end face and the wrap are machined, the outer peripheral surface of the end plate is formed therein with a circumferencial groove to provide jaw finger engaging surfaces spaced from the first and second end faces of the end plate. Then, radial grooves are formed in the outer periphery of the end plate such that each groove extends between and is open in one of the jaw finger engaging surfaces and in the first end face of the end plate. Thereafter, the semi-finished scroll member is positioned relative to a machine tool such that the first axial end face of the end plate is placed adjacent a back-up member of the machine tool. Then, jaw fingers of the machine tool are moved into engagement with the jaw finger engaging surfaces of the semi-finished scroll member, respectively, and are further moved axially of the machine tool toward the back-up member until the first axial end face of the end plate is urged against the back-up plate, whereby the semi-finished scroll member is firmly fixed to the machine tool and ready for machining of the second axial end face of the end plate and of the spiral wrap thereon. | ||||||

| The scroll elements of a scroll-type compressor are treated employing a lapping tool to achieve increased flatness of the base surface and increased smoothness of the side walls of the involute wrap. This reduces flank leakage, tip leakage, and thrust friction losses. The lapping device that is placed against the scroll element has a radially extending base and a generally spiral wrap, the wrap generally matching that of the scroll element workpiece. The lapping device wrap has axially erect walls and a radially flat tip surface. After engaging the scroll element work piece, the lapping device is moved relative to the scroll element in an orbiting motion. A suitable lapping compound is introduced at least between the lapping device wrap tip surface and the base surface of the scroll element, and, if desired, also between the side walls of the lapping device wrap and the side walls of the scroll element wrap. The lapping compound can be introduced directly or in a gas flow. | ||||||

| A method of machining, with a formed tool, a first rotor and a second rotor with mutually complementary meshing threads involves rotating a first workpiece about a longitudinal axis of the workpiece. The tool makes one or more passes along the longitudinal axis of the workpiece as the workpiece rotates so as to remove material, thereby forming the flanks of each helix of the first rotor's thread. The value of at least one of the parameters that collectively define the relative position and relative movement of the workpiece and formed tool is varied during each pass so as to vary the lead of the thread. The above steps are repeated for a second workpiece, thereby forming the second rotor. Adjustments are made to at least one of said parameters during one or more of the passes in order to maintain mutually complementary shapes of the threads of the rotors. | ||||||

| In a scroll machining method, a scroll has a disc-like end plate and a scroll wall extending from a first side surface of the disc-like end plate, and the scroll is driven to rotate around a center axis C of the scroll, and a first cutter machines a side wall surface of the scroll wall while the scroll is rotating. The first cutter is a non-rotary cutter. When the scroll is machined, the scroll rotates around its center axis, and the first cutter does not rotate around its axis, thereby improving the scroll's machining precision and machining efficiency. | ||||||

A distance that the first inward-protruding portion protrudes into the volume is greater than a thickness of the first inward-protruding portion such that removal of the first inward-protruding portion results in a first intake opening in the outer wall. The first intake opening provides a path for a flow of refrigerant into the volume. | ||||||
