ABSTRACT:
The tooth shape at around the pitch circle of the outer tooth gear of the pinion to be connected to the prime mover or driven shaft has a tooth surface which is in axial direction at around the central portion of the tooth width and which contacts at around the tooth width end at the allowable displacement angle and the backlash is made small and the outer tooth gear of the pinion is crowned in to an exponential function curve. The precession vibration and the torsional vibration at a high speed rotation can be suppressed because of the small backlash. The crowning curve is exponential function which causes the contacting point to move toward the tooth width end as the displacement increases and the radius of curvature becomes larger as the point on the curve approaches to the tooth width end, so that even when the contacting gear number decreases when displaced, the increase in the contacting stress is suppressed and a larger power can be transmitted as compared to the conventional design.
