摘要
为了保证双螺杆压缩机转子在工作运行时的平稳性,提出了一种基于离散像素法的啮合间隙布置方法,根据像素筛选原则及间隙判定原则,结合齿轮啮合及磨损原理,基于双螺杆压缩机转子的齿廓型线特征以及转子在加工工况下的热膨胀仿真结果,对双螺杆压缩机阴阳转子的齿间间隙布置方法进行了研究,利用所提方法可在一对无啮合间隙的阴阳转子的端面型线上合理布置齿间间隙,调整转子啮合位置,减小双螺杆压缩机运行过程中的振动和磨损,降低运行功耗。
To ensure the stability of the twin-screw compressor rotors,a meshing clearance arrangement method was proposed based on the discrete pixel method.According to the principles of the pixel selection and clearance determination,combined with the principles of gear engagement and wear,the inter-lobe clearance arrangement method of the male and female rotors for twin-screw compressors was studied based on the characteristics of the tooth profiles of the twin-screw compressor rotors and the thermal expansion simulation results of the rotors under the processing conditions.The proposed method was used to arrange the inter-lobe clearances on the end face profiles of a pair of male and female rotors without meshing clearances reasonably,adjust the rotor meshing positions,reduce the vibrations and wear during the operations of the twin-screw compressors,and reduce the operation power consumptions.
