- Effect of Weld Deformation on Coaxiality of Scroll Compressor Bearings
抄録
<p>In order to prevent global warming, there is a need to reduce emissions of carbon dioxide, a greenhouse gas, and there is a demand for compressors for refrigeration and air conditioning to be more efficient and reliable. This paper focuses on scroll compressors and discusses weld deformation, which affects both efficiency and reliability. A scroll compressor consists of a cylindrical casing with a lid cap and bottom cap welded circumferentially to both ends, in which the compression element and electric motor are hermetically sealed and mounted. The frame and bottom frame, which comprise the bearings, are plug-welded to the casing, and a reduction in the coaxiality of these two parts is a problem that directly affects the performance and reliability of the compressor. Analytical investigation of the weld deformation of a scroll compressor revealed the following. To ensure the coaxiality of the frame and lower frame, it is important that the clearance between the casing and the frame/lower frame during plug welding be uniform. And if the clearance is not uniform, the frame and lower frame will tilt due to weld deformation, resulting in deterioration of the coaxiality.</p>
