摘要

螺桿壓縮機具有結構簡單、工作可靠、操作簡單和系統獨特的優點，因此在空氣動力、製冷空調等各種工程中獲得了廣泛的應用，是一種應用前景十分廣闊的新型壓縮機。本研究則是透過對螺桿壓縮機的組裝流程與各零件尺寸設計進行深入研究，找出螺桿壓縮機的三個重點精度，利用所發展的一維及二維組裝模擬軟體進行組裝模擬分析，探討其模擬分析結果，得到組裝後可能發生的情況與組裝後的不良率，而針對原始設計尺寸提供建議加以修改，改善螺桿壓縮機的良率與組裝上的困難，降低時間與人力成本，並提供設計者往後在設計時的參考，以縮短設計週期。

Twin screw rotor compressor has the advantages of simple structure, unique system, and reliable and easy operation; therefore it is widely used in various construction works involving aerodynamics and refrigeration air conditioning, etc., making it a new compressor model with a broad application future. This study intends to determine the three key precision parts of screw compressors by making an in-depth research into the assembly process of the twin screw rotor compressor and the size design of various parts. By utilizing and analyzing the results obtained from the 1-D and 2-D assembly simulation software developed to analyze the assembly process, possible situations and the defective rate that may occur after assembly was obtained. Modification advice was therefore proposed based on the original design and size, in order to improve the yield rate of the twin screw rotor compressor, reduce any difficulties in assembly, and cut down on both labor cost and time, while providing future designers with some reference for shortening the design period.
