    • A scroll compressor can be provided with different wrap thicknesses to compensate for the different material properties of the orbiting and fixed scroll elements. The concept of different wrap thicknesses also aids in the select-fitting of parts and in the provision of and adjustment of a clearance or spacing between the wrap elements. Additionally, in the manufacture of a scroll compressor, the total wrap thickness of the two wraps is kept constant within narrow tolerances while the individual wrap thicknesses are allowed to vary over a predetermined range. The cutting tools used are sized such that even if they differ in their cutting diameters, the combined cutting diameters, and therefore the total wrap thicknesses, are constant within narrow tolerances. This permits the tools to be used and resharpened until their cutting diameters fall below the minimum acceptable diameter.
    • 涡旋压缩机可以设置有不同的包裹厚度,以补偿轨道和固定涡旋件的不同材料特性。 不同包裹厚度的概念还有助于部件的选择配合,以及提供和调节包裹元件之间的间隙或间隔。 此外,在涡旋压缩机的制造中,两个包装的总包裹厚度在窄公差范围内保持恒定,同时允许单个包装厚度在预定范围内变化。 所使用的切削工具的尺寸使得即使它们的切割直径不同,组合的切割直径也因此总包裹厚度在窄公差范围内是恒定的。 这允许使用工具并重新硬化直到它们的切割直径低于最小可接受的直径。
