Abstract: Controllable modification of
cone-generated cylindric worm gearing has been carried out. The
tooth contact state of modified gearing can be controlled by
selecting the positions of contact points of worm surface and
the correction amount of curvature. The modification machining
can be conveniently implemented by changing the geometrical
sizes and setting parameters of grinding wheel. Therefore the
research has better scientific basis and practical value.
