Abstract
(EN)
A thrust bearing assembly, a compressor, and a refrigerant circulation system. The thrust bearing assembly comprises: a first thrust bearing (6), having a first thrust surface (62) and a first positioning surface (61) disposed on the same side of the first thrust bearing (6), the first thrust surface (62) being located on the radial inner side of the first positioning surface (61) and axially protruding outwards with respect to the first positioning surface (61); a second thrust bearing (9), having a second thrust surface (92) and a second positioning surface (91) disposed on the same side of the second thrust bearing (9), the second thrust surface (92) being located on the radial inner side of the second positioning surface (91) and axially protruding outwards with respect to the second positioning surface (91), the second thrust surface (92) being opposite to the first thrust surface (62), and the second positioning surface (91) being opposite to the first positioning surface (61); and a positioning ring (8), provided between the first thrust bearing (6) and the second thrust bearing (9), and comprising a first matching surface (81) attached to the first positioning surface (61) and a second matching surface (82) attached to the second positioning surface (91). The provision of the positioning ring between the thrust bearings makes it convenient to adjust the clearance of the thrust bearing assembly.

L'invention concerne également un ensemble palier de butée, un compresseur et un système de circulation de réfrigérant. L'ensemble palier de butée comprend : un premier palier de butée (6), comportant une première surface de butée (62) et une première surface de positionnement (61) disposée sur le même côté du premier palier de butée (6), la première surface de butée (62) étant située sur le côté interne radial de la première surface de positionnement (61) et faisant saillie axialement vers l'extérieur par rapport à la première surface de positionnement (61) ; un second palier de butée (9), comportant une seconde surface de butée (92) et une seconde surface de positionnement (91) disposée sur le même côté du second palier de butée (9), la seconde surface de butée (92) étant située sur le côté interne radial de la seconde surface de positionnement (91) et faisant saillie axialement vers l'extérieur par rapport à la seconde surface de positionnement (91), la seconde surface de butée (92) étant opposée à la première surface de butée (62) et la seconde surface de positionnement (91) étant opposée à la première surface de positionnement (61) ; et une bague de positionnement (8), disposée entre le premier palier de butée (6) et le second palier de butée (9), et comprenant une première surface d'adaptation (81), fixée à la première surface de positionnement (61), et une seconde surface d'adaptation (82), fixée à la seconde surface de positionnement (91). La disposition de la bague de positionnement entre les paliers de butée facilite le réglage du jeu de l'ensemble palier de butée.
