SCROLL COMPRESSOR AND METHOD OF MANUFACTURING THE SAME

摘要

A scroll compressor includes a fixed scroll including a spiral unit, an orbiting scroll including a spiral unit and combined with the spiral unit of the fixed scroll to form a compression chamber for compressing refrigerant, a main shaft for transmitting drive power to the orbiting scroll, an electric motor unit configured to rotate the main shaft, and a first balancer for compensating unbalance of the orbiting scroll with respect to a rotation center of the main shaft. The first balancer has an outline in a cylinder shape, and includes a high-density part made of a high-density material, and a low-density part made of a low-density material having a density lower than a density of the high-density material.
