The purpose of this study is to enlarge the range of design applicability and to improve the engagement performance by introducing a coefficient of transverse shift as a new factor in designing of crossed helical gears. Basic designing theories are first reviewed. Designing equations are newly formulated. On this basis, problems related to the engagement limit are examined. A large number of limit diagrams are then prepared. An optimal designing system is established on the basis of the theoretical study and the study of limit diagrams. The designing system and technique are tested by extensive designing computation and trial manufacture of gears. It is confirmed that the introduction of a coefficient of transverse shift is considerably effective in expansion of designing feasibility and improvement of the engagement performance. The gears manufactured for trial are smoothly engaged. The practicability is thus verified.
