Abstract:
A gas thrust bearing, a bearing assembly, a compressor, an air conditioner, and an automobile. The bearing assembly comprises: a rotor (10) having a rotating shaft (12) and a thrust collar (11); a bearing housing (21) sleeved on the rotating shaft (12); and a plurality of foil groups arranged in the circumferential direction of the bearing housing (21), wherein each foil group comprises: a bump foil and a top foil. The top foil comprises a first top foil section (22) and at least two second top foil sections (231, 232). The first top foil section (22) is parallel to the surface of the thrust collar (11). An inclination angle is formed between the at least two second top foil sections (231, 232) and the surface of the thrust collar (11). According to the rotation direction of the rotor (10) during operation, the first top foil section (22) is located at the downstream of the at least two second top foil sections (231, 232), and the inclination angle of the second top foil sections (231, 232) located at the upstream relative to the surface of the thrust collar (11) is greater than the inclination angle of the second top foil sections (231, 232) located at the downstream relative to the surface of the thrust collar (11).
