Meshing Analysis of Non-parallel Double-roller Enveloping Hourglass Worm Gearing
摘要
Abstract
To eliminate the backlash and improve the precision and efficiency of enveloping worm, by analyzing the shortcomings in the existing non-backlash worm gear sets, non-parallel double-roller enveloping hourglass worm gearing was pror~sed based on the research of non-backlash double-roller enveloping hourglass worm gearing. Two rows of rollers were assigned to misplace and there was a certain de- fection angle between the roller axis and the radial. The working principle was introduced. According to the theories of differential geome- try and space engagement theory, the dynamic and static coordinate system based on worm gear pair and the moving coordinate system based on the contacting point were established. The tooth surface equations of worm and contacting line equations of worm gear were de- duced. The formulas of meshing limit function, induced normal curvature, lubrication angle and rotation anise of the non-parallel doubleroller enveloping hourglass worm gearing were derived by means of the theory of differential geometry. The simulation was conducted using MATLAB software IR and T, which impacted the engagement performance of this transmission, were anayzed. The numerical example showed that c2 should not be more than 10 cm,R should be controlled within 8 to 15 cm, and should be controlled within 28° to 50°, for effectively improving the meshing performance of the non-parallel double-roller enveloping hourglass worm gearing.关键词
