Abstract: A method of modifying the
hourglass worm gearing with developable tooth surface has been
proposed. The method has been applied to relieve the worm
gearing from the influence of manufacture errors. The tooth
contact and kinematic precision of the modified worm gearing
with manufacture error has been investigated by the TCA method.
The results show that by the modification, the edge contact
resulting from the manufacturing error is avoided or effectively
relieved and the kinematic error of the worm gearing is
obviously reduced.
