IMO 形ねじボンプの工作に関する研究（第1報） Studies on Machining of IMO Screw Pump, First Report 両角, 宗晴 降旗, 建治 In this paper, we deal with the fundamental research for designing and machining the IMO Screw Pump. As the results, the shape of the screw thread of which the corner has been chamfered, the generating curve of the main screw thread meshing with the above chamfered screw thread, the contact state between the two screw thread surfaces mentioned above, the static equilibrium condition of the chamfered screw and the theoretical pump discharge are analytically made clear. The authors show a numerical example with a view to facilitating the practical utilization of the theoretical formulas obtained in this paper. Then the right-handed main screw of double threads and the chamfered left-handed screw of double threads are shaped as a helical gear with a gearshaper. Finally the results of the calculated analysis are compared with those of the experiment.
