Abstract:
A rotor assembly, a compressor and an air conditioner. The rotor assembly (10) comprises a first rotating shaft (11) and a first rotor (12), which is rotatably arranged on the first rotating shaft (11). The first rotor (12) comprises a plurality of first helical blades (121), wherein a first tooth groove (122) is formed between two adjacent first helical blades (121); and an air suction end (123) of the first rotor (12) is provided with at least one oil thrower groove (124), so as to make a lubricant enter the first tooth grooves (122) by means of at least one oil thrower groove (124). It is ensured that the lubricant can fully lubricate and seal the first tooth grooves, such that the compressor operates more smoothly, abrasion on the helical blades is reduced, and the service life of the compressor is prolonged.
