Abstract

The invention provides a compressor comprising a rotor, a crankshaft and connecting keys, wherein a shaft hole is formed in the rotor, and first key slots are formed in the wall of the shaft hole; the crankshaft penetrates into the shaft hole, second key slots matched with the first key slots are formed in the peripheral surface of the crankshaft, and the first key slots and the second key slots form locating spaces; and the connecting keys penetrate into the locating spaces so as to fix the rotor and the crankshaft, and the overall dynamic balance of the crankshaft and the rotor is improved through arranging the connecting keys and the locating spaces. The crankshaft is connected with the rotor through the connecting keys to ensure that the interference fit between the crankshaft and the rotor is not needed, so that the assembling complexity of the crankshaft and the rotor is reduced, the production efficiency of the compressor is increased, and the production cost of the compressor is reduced. The mass distribution conditions of the rotor and the crankshaft can be changed through changing the sizes of the locating spaces or changing the masses and volumes of the connecting keys, so that the overall dynamic balance of the rotor and the crankshaft is improved, and furthermore the operation reliability of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a compressor. Background technique [0002] At present, in order to reduce the vibration and noise during the operation of the rotary compressor and improve the reliability of the rotary compressor, it is generally necessary to install a balance structure on the upper end and the lower end of the rotor, so that the rotating parts of the rotary compressor can meet certain requirements during operation. Force balance and torque balance requirements, thereby reducing vibration and noise when the rotary compressor is working, and improving its reliability. [0003] Since the balance structure needs to be installed on both the upper and lower parts of the rotor, the assembly complexity is increased, and it is easy to cause the problem that the two balance structures cannot play a balancing role due to improper fit of the two balance structures.
