[0002] In the related art, the transmission structure of the rotary compressor, such as Figure 7 As shown, generally the motor is on the top and the compression mechanism is on the bottom. The motor drives the compression mechanism to compress through the crankshaft. However, the structure of the rotary compressor in which the motor and the compression mechanism are arranged up and down has a large height and a high center of gravity, which is not conducive to vibration.
Moreover, since the crankshaft includes a long axis and a short axis, the vibration caused by the deflection of the crankshaft and the unbalanced inertial force is not easy to eliminate

The invention discloses a rotary compressor, an air conditioner outdoor unit having the rotary compressor and an air conditioner, the rotary compressor comprises a casing, a compression mechanism anda motor, an air suction port and an exhaust port are formed on the casing; and the compression mechanism comprises a cylinder assembly, a main bearing, a sub-bearing, a piston, a sliding piece and a crankshaft. The cylinder assembly comprises at least one cylinder, the cylinder has a cylinder chamber and a sliding piece groove, the piston sleeves the crankshaft, an air inlet and an air outlet areformed on the compression mechanism, the air inlet is connected to the air suction port, the air outlet is connected to the exhaust port, and the sliding piece is movably disposed in the sliding piecegroove; and the motor is arranged radially outward of the compression mechanism. The overall height of the rotary compressor is greatly reduced, and the center of gravity is relatively low, so that the vibration due to the high center of gravity of a conventional rotary compressor can be well reduced, the length of the crankshaft is also reduced, so that the vibration caused by the crankshaft deflection and the unbalanced inertial force can be reduced.
Description
technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a rotary compressor and an air conditioner outdoor unit and an air conditioner having the same. Background technique [0002] In the related art, the transmission structure of the rotary compressor, such as Figure 7 As shown, generally the motor is on the top and the compression mechanism is on the bottom. The motor drives the compression mechanism to compress through the crankshaft. However, the structure of the rotary compressor in which the motor and the compression mechanism are arranged up and down has a large height and a high center of gravity, which is not conducive to vibration. Moreover, since the crankshaft includes a major axis and a minor axis, vibrations caused by crankshaft deflection and unbalanced inertial forces are not easily eliminated. Contents of the invention [0003] The present invention aims to solve at least one of the technical prob...
