Studies on tooth surface modification of worm gears (3rd report, for worm gears with a large number of worm threads)

摘要

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.
