PROBLEM TO BE SOLVED: To simplify unclear design, analysis, processing and evaluation and the like and assure and improve accuracy accompanying with this simplification as its first theme, more practically to cause a design reference point to become a contact point when the design reference point is applied as one item and a gear tooth is rotated to pass through the design reference point and to cause a tooth trace passing through the design reference point is placed on a pitch plane and to cause a tooth thickness and a groove width of tooth surface 1 and tooth surface 2 to be varied in well-balanced state in a tooth trace direction on a pitch plane while holding a substantial specified rate as its second theme.SOLUTION: All the adjoining tooth surfaces are formed independently, a tooth profile on the design reference plane passing through a design reference point is set as a bus line and a rotating plane with a straight line on the design reference plane in parallel with a gear center line being applied as a center. |
