Abstract
Disclosed are a main bearing housing (40) for a scroll compressor, a dynamic scroll component (60) for the scroll compressor and the scroll compressor. The main bearing housing (40) comprises an anti-thrust surface (S1) for supporting the dynamic scroll component (60), an uneven construction (W) is formed on at least one portion of the anti-thrust surface (S1) to enable a lubricant to form a fluid dynamic pressure lubricating oil film between the main bearing housing (40) and the dynamic scroll component (60). The dynamic scroll component (60) comprises an anti-thrust surface (S2) for being supported by the main bearing housing (40), wherein an uneven construction (W) is formed on at least one portion of the anti-thrust surface (S2) to enable the lubricant to form a fluid dynamic pressure lubricating oil film between the main bearing housing (40) and the dynamic scroll component (60). The scroll compressor comprises at least one of the main bearing housing (40) and the dynamic scroll component (60). No matter whether the dynamic scroll component (60) can produce sufficient oblique circumferential translation or not, a good lubrication can be provided between the dynamic scroll component (60) and the main bearing housing (40).
