This thesis is mainly concerned with the principle of conjugate surface in singular points. In the light of this principle, a new -type worm gear drive, namely 0?involute-enveloping worm gear drive, is systematically investigated from the aspect of theoretical analysis and experimental research.
This thesis classifies the conjugate boundary among the category of singular question on conjugation. Based on the first -type limit and the second -type limit, a detailed research is carried ou...
