In worm gears, it is very important to modify the wheel tooth surface to give an entrance gap between the worm and worm-wheel surfaces. A new modification method that can be applied to worm gears with an arbitrary profile was proposed in our previous report. However, it was found that interference occurs between the worm and wheel surfaces when the method is applied to worm gears with a large number of worm threads. In this report, two techniques are introduced to prevent the interference and to obtain good entrance and exit gaps. One is to compensate for the tilting angle of a hob axis in the cutting wheel and the other is to use a hob with a larger thread number than that of the worm. The meshing clearance which indicate the meshing characteristics of worm gears are calculated and shown by means of contour line diagrams by changing the tilting angie of the hob axis and the number of hob threads. As a result, it was found that these techniques are very useful for worm gears with a large number of worm threads.
