When hypoid gears are used as high-reduction gears with a 90-degree shaft angle, the expected gear cannot be obtained by a calculation method for designing general hypoid gears. In our first report, we set up a fundamental formula regarding the design by a difference of the pinion shape. In the present report, by using the results, the calculation method with adjustability of the tooth bearing and degree of freedom for designing is investigated for the case in which the blanks of pinion and gear are of conical shape. As a result, it is clarified that a method for designing which accomplishes the above purpose is can be obtained if the gear spiral angle is freedom as a variable.
