The curve is the ratio between δ obtained by Eq. (36) and 0.5 times back- lash b, that is δ/b. According to the judgement of gear pair state, the gear pair is in contact state when the ratio is greater than 1 or less than − 1, and the deformation is |δ| −...

from a driving gear to a driven gear. More precisely, the condition of conjugacy requires that: (1) the ratio of the velocity of the two gears in mesh be constant and (2) that the ratio of the velocity of the two gears be equal to the ratio of the numbers of teeth of the two ...
When the gear ratio is substantially different from 1, the limit dedendum of the pinion is used to locate the pitch line element as shown in FIG. 20, such that undercut of the pinion at point M is just avoided. Undercut on the gear is not usually a factor. In any event, the loca...
