LZG-30单头螺杆干式真空泵的建模与仿真
摘要
本文的研究对象,螺杆型干式真空泵,吸入腔没有任何工作液,保证了空间用泵无污染;没有油蒸汽排放,保证清洁的外部环境。由于转子齿面之间有间隙,因而可以抽除含有灰尘或腐蚀性的有毒气体。本课题主要集中在以下几个方面:基本原理的干式螺杆真空泵,阴阳转子螺杆型线的研究,螺旋型面线是单边等螺距型线,演绎数学的计算,建立几何模型面型线方程推导,然后螺旋齿面方程推导。几何特征研究等。
设计完成后应用solidworks软件做运动仿真对真空泵转子做三维建模,并且模拟转子运动展示其工作过程.
关键词:干式螺杆真空泵转子型线三维建模运动仿真

Modeling and Simulation of  LGZ-30 single screw dry vacuum pump
Abstract
The research object of this paper, Dry screw vacuum pump, The suction chamber with no working fluid, ensure the space is pumped from pollution; No oil vapor emissions, guarantee the clean of the external environment. Due to the gaps between the rotor tooth surface of Yin and Yang, thus it can be pumped in addition to containing dust, or corrosive, poisonous gases. The author studies mainly focus on the following aspects: the basic principles of dry screw vacuum pump. Yin and Yang screw type line of research. Screw type face line made bilateral symmetric circular arc line, deduce the mathematical expressions of meshing principle, establish geometric model face type line equation is deduced, and then screw tooth surface equation is deduced. Geometric characteristics research, etc.
After the design pleted using SolidWorks software to do motion simulation to do 3D modeling of vacuum pump rotor. And the simulation of rotor motion display their works.
Keywords: dry screw vacuum pump rotor type line Three-dimensional modeling
Motion simulation
