摘   要

 本文闡述了一小型螺桿壓縮機(jī)的設(shè)計(jì)過(guò)程。簡(jiǎn)述了螺桿壓縮機(jī)的基本結(jié)構(gòu)、工作過(guò)程、主要特點(diǎn)和分類。分析了型線的設(shè)計(jì)過(guò)程，轉(zhuǎn)子的幾何特性和熱力性能的計(jì)算方法。

Abstract

This paper described the design process of a small screw compressor, which outlined the basic structure of the screw compressor, the working process, the main characteristics and classification. This paper also analyzed the design process of lines, the geometry features of the rotor and the calculation method of thermodynamic property.

Based on the analysis of the design process of lines, geometric characteristics and calculation methods of thermal performance, this paper selected the unilateral asymmetry cycloid - sales arc tooth profile of the screw compressor rotor type lines for analysis and calculation using MATLAB and other tools. After above steps, the equation-based and sketch-based line are given the calculation of geometry features and thermal performance are also made. On the basis of rotor design, this paper gave stress analysis and selected bearing and other parts using a variety of analysis software to. Afterwards, the paper established three-dimensional models of the various parts of the screw compressor and carried out the assembly to complete the three-dimensional modeling of the screw compressor. With the application of ADAMS, the paper established motion simulation of the assembly imported from SOLIDWORKS, which could explain the issue vividly and intuitively.

Key words: Screw compressor, three-dimensional modeling, MATLAB, motion simulation
