Evaluation method of torque transmission feature (2nd Report)

Abstract

Last presentation, empirical formula on maximum transmission torque that is based on geometrical parameter of intersection volume and its angle was proposed. This parameter is changed by clearance easily. Desirable torque transmission feature must not change geometrical parameter easily. So, we evaluated 3 type of feature Hexagon, Oval and Square by concentration of intersection and change of parameter on clearance. Finally, we decided oval feature is best feature of three.
