Abstract
A rotor assembly, a compressor and an air conditioner are provided. The rotor assembly includes a first rotation shaft and a first rotor rotatably arranged on the first rotation shaft. The first rotor includes a plurality of first screw blades, and a first tooth slot is formed between two adjacent first screw blades; a suction end of the first rotor has at least one oil slinger slot, to allow a lubricant to enter the first tooth slot through the at least one oil slinger slot. It is ensured that the lubricant can fully lubricate and seal the first tooth slot, so that the compressor can run more smoothly, reduce wear of screw blades and improve the service life of the compressor.
