Analysis Of Contact On Multi-parameter Modified Planar Double-enveloping Worm Pairs

In this thesis, planar double-enveloping worm gear pairs is the research object, combined with space Meshing theory, derived from the multi-parameter modification of the mesh equation . The contact line type of original type Worm were analysised, Contact line type of amend-type worm gear pair were recognized are typeâ… and typeâ…¡T hrough the point of theoretical research of transformation point , the instantaneous contact line of the transformation point will appear first-enveloping contact line in the tooth surface, before and after the transformation point of the instantaneous were typeâ… andâ…¡contact line in the tooth surface, the contact line type is defined as the typeâ…¢. animation instantaneous contact line of the typeâ…¢has rendered the processDifferent types of contact line performance analysis and discussion of the single parameter modification and amendment of three parameters simultaneously, the changing of the contact line and meshing performance comparison under different correction variation,The oretical research was supported by Modified Double Enveloping Worm Gear tooth surface when the axial misalignment of the contact line type judging method: using MATLAB software to solveâ… andâ…¡type 2 boundary curves, there are two curves of I-type worm gear surface contact line, there are not two curves ofâ…¡-type worm gear surface contact line.
