    • The compressor comprises a bearing hub (40), defining a radial bearing (41) having a first and a second end portion (40a, 40b) and supporting a crankshaft (50) having an eccentric end portion (55) supporting the larger eye (61) of a connecting rod (60) coupled to the piston (30), for example, by a smaller eye (62) mounted around a piston pin (63). The second end portion (40b) and, optionally, the first end portion (40a) of the bearing hub (40) and the larger and smaller eyes (61, 62) of the connecting rod (60) are internally provided with bushings (80). End portions (40a, 40b) of the bearing hub (40) and of the larger and smaller eyes (61, 62) may have their structure resistant to the pressing of a confronting compressor component supported on said end portions, or further present a terminal portion (40c, 40d, 61a, 62a) elastically deformable together with a confronting terminal portion of the associated bushing (80).
    • 压缩机包括轴承座(40),其限定具有第一和第二端部(40a,40b)的径向轴承(41)并且支撑具有支撑较大眼睛的偏心端部(55)的曲轴(50) 例如通过安装在活塞销(63)周围的较小的眼睛(62)连接到活塞(30)的连杆(60)的连接杆(61)。 第二端部(40b)和可选地,轴承座(40)的第一端部(40a)和连杆(60)的越来越小的眼睛(61,62)内部设置有衬套(80) )。 轴承座(40)的端部(40a,40b)和越来越小的眼睛(61,62)的结构可以具有抵抗支撑在所述端部上的面对的压缩机部件的按压的结构,或进一步具有端子 与相关衬套(80)的相对的端子部分一起弹性变形的部分(40c,40d,61a,62a)。
