A compressor, including: a first rotor being rotatable around a first axis, the first rotor including a first portion and a second portion; and a first shaft carrying the first portion and the second portion, the first shaft having a first end and a second end that are oppositely arranged. The first rotor is configured to be applied with a preset acting force in a direction from the first end toward the second end or from the second end toward the first end during rotation. The size of the compressor can be reduced with the displacement of the compressor remaining substantially unchanged.

Rotor assembly, compressor and air conditioner

A rotor assembly, a compressor and an air conditioner. The rotor assembly includes a first rotor, including a first working portion and a second working portion coaxially arranged, the first working portion and the second working portion are rotatable about a first axis; the first working portion includes a plurality of first helical blades, with a first blade groove being formed between adjacent two of the plurality of first helical blades; at least one first air pressure groove is provided on a first end face of the first working portion away from the second working portion.

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.
