Abstract

See full text

A scroll compressor includes: a rotary shaft; a compression mechanism including an orbiting scroll and a non-orbiting scroll, an extension portion of the orbiting scroll engaging with an eccentric structure of the rotary shaft via a bushing and a driving bearing having an axial height L1; and a counterweight located on the bushing, a mass center of the counterweight being located above an axial lower end of the driving bearing and having an axial distance L2 to the axial center of the driving bearing, and the ratio R of the axial distance L2 to the axial height L1 satisfying: 0.1≤R≤0.4. The scroll compressor can reduce the contact and wear between the bushing and the driving bearing and reduce the requirements for the manufacturing precision and the mounting precision of components such as the counterweight and the bushing, achieving optimized system design.
