摘　　要：对啮合同向旋转双螺杆几何学和无间隙全啮合双螺杆四面体间隙的几何形状与体积做了详细的探讨,并建立了四面体间隙的数学模型.澄清了过去对四面体间隙形状的种种推测,为提高双螺杆机械的设计水平提供了较为准确的依据.The geometry of intermeshing co- rotating twin- screw, especially the shape and volume of the tetrahedral gap of the equipment were studied throughly and the mathematical model of the volume of the gap was proposed. The results in this paper clear up a lot of misunderstanding of the shape of the tetrahedral gap and provide a fairly exact model for the design of twin-screw extruders.
