Abstract
A compressor and a refrigeration device are provided. The compressor has a crankshaft, a connecting structure, and an avoidance part arranged on the connecting structure and/or the crankshaft. The avoidance part is located at a position where the connecting structure is matched with the crankshaft. The avoidance part is configured to be suitable for avoiding at least one of the connecting structure and the crankshaft. A gap between the crankshaft and the connecting structure is increased through the arrangement of the avoidance part, so that the avoidance part can avoid the crankshaft when the crankshaft is obliquely deformed.
Claims15
A compressor comprising
- a crankshaft comprising:
- an eccentric portion;
- a first shaft portion connected eccentrically with the eccentric portion, the first shaft portion comprising:
- a first cylindrical portion;
- a second cylindrical portion;
- a first avoidance portion disposed between the first cylindrical portion and the second cylindrical portion;
- and
- a second avoidance portion disposed between the second cylindrical portion and the eccentric portion;
- and
- a second shaft portion connected eccentrically with the eccentric portion, the second shaft portion comprising:
- a third cylindrical portion;
- and
- a third avoidance portion disposed between the third cylindrical portion and the eccentric portion;
- a first bearing comprising a fourth cylindrical portion sleeved over the second cylindrical portion, at least a portion of the first avoidance portion, and the second avoidance portion of the first shaft portion of the crankshaft;
- and
- a second bearing comprising a fifth cylindrical portion sleeved over the third cylindrical portion and the third avoidance portion of the second shaft portion of the crankshaft,
- wherein:
- each of the first, second, and third cylindrical portions have a respective diameter, each of the respective diameters are substantially equal to each other;
- the first avoidance portion forms a first bilateral gap between the first shaft portion and the first bearing;
- the second avoidance portion forms a second bilateral gap between the first shaft portion and the first bearing;
- the third avoidance portion forms a third bilateral gap between the second shaft portion and the second bearing;
- a minimum value of each of the first, second, and third bilateral gaps is δ0;
- a difference between a maximum value of each of the first, second, and third bilateral gaps and δ0 is δ;
- and
- δ is less than δ0.
