Refrigerating equipment and compressor thereof

The utility model discloses a refrigerating equipment and compressor thereof, establish including bent axle, cover and establish at the cylinder in the roller outside and set up the last flange at the cylinder upper surface at the roller of bent axle off -centre portion and cover, wherein, set up bent axle off -centre into the taper shape to serving as reasons the external diameter setting of bent axle off -centre portion, to keep away from the flange crescent to being close to last flange direction, correspondingly, sets up the inner wall of roller for cooperating the circular conical surface with bent axle off -centre. The circle all makes the supporting assembly of toper of beta angle into in conical bent axle eccentric circle and the roller, bears the gravity that comes from rotor and bent axle by terminal surface under the roller, and owing to the area of contact of terminal surface under the obconic roller and lower flange is more than the area of contact of bent axle thrust surface and lower flange, the pressure of terminal surface is smaller under the roller promptly to the degree of wear of roller and lower flange is relatively little, has improved the compressor reliability. On the other hand has increased the wearing and tearing at the interact power between bent axle eccentric circle and the interior circle of roller, reducible bent axle eccentric circle position.
