Beschreibung
Zusammenfassung:	A pump body assembly includes: a crankshaft (1), a first baffle plate (6) and a second baffle plate (7). The crankshaft (1) includes a first eccentric portion (12), a support shaft (13) and a second eccentric portion (15) which are arranged at intervals in an axial direction; the first baffle plate (6) and the second baffle plate (7) are arranged in sequence between the first eccentric portion (12) and the second eccentric portion (15), a first round hole (17) is arranged defined on the first baffle plate (6), the support shaft (13) is arranged in the first round hole (17), so that the first baffle plate (6) and the support shaft (13) form a baffle plate bearing, and the baffle plate bearing has a stress relief structure for reducing a contact stress between the support shaft (13) and the first baffle plate (6). A compressor and an air conditioner includes the pump body assembly. This kind of pump body assembly can reduce bearing wear problems caused by an excessive local stress and prolong service life of the baffle plate bearing.
