制冷压缩机中的轴承安装

BEARING ARRANGEMENTS IN A REFRIGERATION RECIPROCATING COMPRESSOR
摘要：
The compressor comprises: a crankcase (10) carrying a cylinder (20) and a bearing hub (40) having a first and a second end portions (40a, 40b) and defining a radial bearing (41), in which is housed a crankshaft (50); and a connecting rod (60) coupled to a piston (30) housed in the cylinder (20) and having a larger eye (61) mounted in an eccentric end portion (55) of the crankshaft (50). Each of said end portions (40a, 40b) is defined by a bushing extension (45, 46) affixed in the interior of the bearing hub (40) and having an end portion (45a, 46a) projecting outwards from the bearing hub (40), in order to be elastically and radially deformed when pressed by a confronting portion of the crankshaft (50), which presents coaxiality deviation in relation to the axis (X1) of the radial bearing (41).
摘要（中）：

压缩机包括：承载缸体（20）的曲轴箱（10）和具有第一和第二端部（40a，40b）并且限定径向轴承（41）的轴承座（40），其中容纳有曲轴 （50）; 以及联接到容纳在所述气缸（20）中并具有安装在所述曲轴（50）的偏心端部（55）中的较大的眼睛（61）的活塞（30）的连杆（60）。 每个所述端部（40a，40b）由固定在所述轴承座（40）的内部中的衬套延伸部（45,46）限定，并且具有从所述轴承毂（40）向外突出的端部（45a，46a） ），以便在由曲轴（50）的相对部分按压时相对于径向轴承（41）的轴线（X1）产生同轴度偏差而弹性和径向变形。
