摘    要
本次毕业设计是关于客车空调用涡旋压缩机的结构设计，以及涡旋压缩机的部分零件二维和三维图纸，然后再对主轴进行强度校核。
涡旋压缩机整体结构设计上属于公转型整机结构，其中比较重要的机构包括静涡盘、动涡盘、主轴和防自转机构，其余的部件包括偏心调节机构、平衡块等等。
涡旋压缩机的设计流程大体如下，首先是简单介绍涡旋式压缩机的原理，其次由既定参数和假设条件得到压缩内容积比与吸气容积；再按照设计要求选择涡旋线，通过涡旋线算出涡旋的一些几何数据，并对涡旋线进行修正；将主要的参数通过已知公式进行计算，从而设计出动、静涡盘和其他部分零件。然后用AutoCAD画出二维装配图和部分的二维零件图；后在Pro/E建出静、动涡盘的三维模型和总体结构模型。最终把偏心主轴放在UG里进行受力分析，并完成强度校核。

ABSTRACT
The purpose of this design is to complete the structural design of a scroll compressor for passenger car air conditioning, and the scroll compressor belongs to the volume compressor.
The structure design of the scroll compressor adopts the rotating structure form and the circular involute scroll line. The main mechanism is the static vortex disk, the moving vortex disk, the eccentric spindle, the cylindrical pin coupling, and the other parts, such as eccentric adjustment mechanism, balance block, motor and so on. The design of the scroll compressor first obtains the compression content product ratio and the suction volume according to the design parameters. After that, the suitable scroll line is determined, the main parameters of the vortex part are calculated, and the vortex line is corrected. The main parameters are calculated, and the dynamic and static vortex disk and other parts are designed. Then use AutoCAD to draw the assembly drawing and part drawing, and then draw the three-dimensional and general structure diagram of the moving and stationary scroll with Pro/E. Finally, the force analysis of the crankshaft is carried out by UG8.0, and the strength is checked.
