Rotor assembly and compressor

The invention provides a rotor assembly and a compressor, and relates to the technical field of compressors. The rotor assembly is used for the compressor and comprises a rotor iron core; the counterweight mechanism is arranged on the end surface of the rotor iron core, and the counterweight mechanism is eccentrically arranged on the rotor iron core; wherein the counterweight mechanism comprises a windward side, the windward side is inclined to the end face of the rotor core, and the windward side is used for reducing the wind resistance of the counterweight mechanism rotating along with the rotor core. 本发明提供了一种转子组件和压缩机，涉及压缩机技术领域。转子组件用于压缩机，转子组件包括：转子铁芯；配重机构，设于转子铁芯的端面，配重机构在转子铁芯上偏心设置；其中，配重机构包括迎风面，迎风面倾斜于转子铁芯的端面，迎风面用于降低随同转子铁芯转动的配重机构的风阻。
