Feeding under-cutting of Lorentz wheel cutting method of Hindley hourglass worm gearing is analyzed at first. And the shape of the wheel tooth surface is made clear by the analysis and the measuring method of the wheel by 3-dimensional coordinate measuring machine is proposed. Statical and dynamical tooth contact are analyzed to control the accuracy of manufacturing a pair of Hindley hourglass worm gearing.
