Variable P Angle for Plane Envelope Hourglass Worm
-
摘要: 本文提出一種變β角的平面包絡環面蝸桿,并導出其有吳方程式。以這種蝸桿所形成的傳動將改善小傳動比時蝸桿變尖和根切現象。理論分析使用了北京鋼鐵學院的包絡法及其算符。Abstract: This paper developed a new type hour-glass worm enveloping by a variable P angle of the generating plane, and obtainned all of the equations of the worm. The drive by this worm will improve its profile in appearance sharp-pointed or undercut under the small velocity ratio.This paper was theorized about with the "Methodology of Envelope" devised by Beijing University of Iron and Steel Technology,
