Thrust bearing behaviour in scroll compressors.

Author(s) : GROSS D., ANCEL C., GINIES P.

Summary

The development of scroll compressors requires a precise study of the thrust bearing. The prediction of the contact behaviour between the orbiting scroll and the housing-thrust bearing is one of the most important problems. This thrust bearing contact behaviour has an influence on the lubrication, the compressor reliability and the compressor efficiency. Thus the understanding of this phenomenon thanks to finite elements analysis and lab measurements gave us some information to explain how the orbiting scroll wobbling motion is generated. Another benefit of this study is the knowledge about the creation of the oil film between the two parts while the compressor is running. A direct consequence is the possibility of creating a design which avoids the wear and tear of the thrust bearing, while reducing the qualification time of the product.
