Tremendous Potentiality of Steel Worm Gear Drive;

The article describes the advantages and disadvantages of worm gear drives and the domestic and abroad research.

In this paper the authors introduce a new worm gear drive with ground double profile, expound its features, theoretical background, computed results and EHD lubrication characteristics analysis.

Study and development of worm-drive CAD system;

Involute cylindrical worm-helical gear transmission is to use helical gears to replace worm wheels in traditional worm wheel transmission so as to form a new worm transmission.
