Examines gear teeth mating in unique configurations, suggesting applications in reduction gears.
In this paper, we report the studies on the mating of gear teeth in the case of the pinion without dedendum and the gear without addendum. If the pinion is a driver, the gear teeth mates in arc of recess only, consequently, increases the smoothness of operation. Accordingly, the gear of this type can be applied to a reduction gear. The equations for this tooth profile are expressed by equations (3-6), (3-7) and (3-8), and the equations for tooth thickness are obtained from the following equations given in the 1st. report : numerical formula The gear of this type can be designed by using these equations.
