Abstract: The lubrication behavior of
double enveloping hourglass worm gearing is studied experimently.
The effects of rotational speed of the worm and load on the
formation of the fluid film between engagement tooth surfaces
are investigated in detail, and working angle of this worm
gearing is also analyzed. Some beneficial results are obtained.
Key words:
