    • A compressor includes a closed container, a compression element disposed in the closed container, and a motor disposed in the closed container to drive the compression element via a shaft. The compression element includes a first and second bearings supporting the shaft. At least one cylinder having at least one cylinder chamber is disposed between the first and second bearings, with at least one roller fitted to the shaft disposed in the at least one cylinder chamber. The first bearing is disposed closer to the motor than the second bearing. The first and second bearings have first and second annular grooves formed in first and second opposing surfaces opposed to end faces of the at least one roller. The first and second annular grooves are opened to the at least one cylinder chamber. A width of the second annular groove is larger than a width of the first annular groove.
    • 压缩机包括密封容器,设置在密闭容器中的压缩元件和设置在密闭容器中的电动机,以经由轴驱动压缩元件。 压缩元件包括支撑轴的第一和第二轴承。 具有至少一个气缸室的至少一个气缸设置在第一和第二轴承之间,其中至少一个辊安装在设置在至少一个汽缸室中的轴上。 第一轴承比第二轴承更靠近马达设置。 第一和第二轴承具有形成在与至少一个辊的端面相对的第一和第二相对表面中的第一和第二环形槽。 第一和第二环形槽向至少一个气缸室敞开。 第二环形槽的宽度大于第一环形槽的宽度。

    • A compressor includes a closed container housing a compression element driven by the shaft of a motor. The compression element includes a first and second bearings supporting first and second shaft portions, and at least one cylinder having at least one cylinder chamber disposed between the first and second bearings. At least one roller is fitted to the shaft in the at least one cylinder chamber. The first bearing is disposed closer to the motor than the second bearing. The first and second bearings have first and second annular grooves opened to the at least one cylinder chamber and first and second elastic portions provided in first and second opposing surfaces, respectively. A diameter of the second shaft portion is smaller than a diameter of the first shaft portion. A rigidity of the second elastic portion is smaller than a rigidity of the first elastic portion.
    • 压缩机包括容纳由电动机的轴驱动的压缩元件的密闭容器。 压缩元件包括支撑第一和第二轴部分的第一和第二轴承,以及至少一个具有设置在第一和第二轴承之间的至少一个气缸室的气缸。 至少一个气缸室中的至少一个辊安装在轴上。 第一轴承比第二轴承更靠近马达设置。 第一和第二轴承具有向至少一个气缸室敞开的第一和第二环形槽,分别设置在第一和第二相对表面中的第一和第二弹性部分。 第二轴部的直径小于第一轴部的直径。 第二弹性部的刚性小于第一弹性部的刚性。
