Abstract

The invention provides a scroll compressor and an air conditioner. The scroll compressor comprises a crankshaft and a support sleeved on the crankshaft; a bearing is arranged between the crankshaft and the support; a damping member is further arranged between the crankshaft and the support; and when the crankshaft swings in the radial direction, the damping member can be extruded to deform. According to the invention, the damping member is arranged between the crankshaft and the support; when the crankshaft swings in the radial direction, the crankshaft applies force to the damping member, so that the damping member is forced to deform; the deformed damping member generates friction heat; and then, swing vibration of the crankshaft is converted into heat of the damping member for counteraction, so that vibration of a compressor shaft system can be essentially reduced, the noise level of the compressor is improved, and the operation reliability of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a scroll compressor and an air conditioner. Background technique [0002] For scroll compressors, the compression process of the pump body is driven by the crankshaft. At the same time, in order to ensure the smooth operation of the shaft system, two bearing structures (upper bearing and lower bearing) are generally set to constrain it. However, during the operation of the shafting, due to the fluctuation of the load during the rotation period, the shafting will oscillate to a certain extent in the radial direction, and the vibration caused by this oscillating will be absorbed by the bearing. Typically, the vibrations absorbed by the bearings are transmitted to the compressor casing, where they are released into the air as noise. [0003] In order to reduce the noise generated by the shafting vibration, sound insulation cotton is usually pasted on th...
