Title (EN) CONJUGATE CURVE-BASED CYLINDRICAL GEAR MESHING PAIR HAVING MULTIPLE CONTACT POINTS
(FR) PAIRE ENGRENÉE D'ENGRENAGES CYLINDRIQUES À BASE DE COURBES CONJUGUÉES AYANT PLUSIEURS POINTS DE CONTACT
(ZH) 基于共轭曲线的多点接触圆柱齿轮啮合副
Abstract:
(EN) A conjugate curve-based cylindrical gear meshing pair having multiple contact points comprises a concave gear and a convex gear meshing with each other via contacting at multiple points. A meshing curved surface of the concave gear and the convex gear is a tubular curved surface, and a contact curve formed by meshing points on a curved tooth surface of the concave gear and a contact curve formed by meshing points on the convex gear are conjugate curves. The meshing pair is meshed by contacting a tooth surface of the concave gear with a tooth surface of the convex gear at multiple points at the same time, and contact trajectories of contact points in respective tooth surfaces are all smooth spatial curves.
(FR) L'invention concerne une paire engrenée d'engrenages cylindriques à base de courbes conjuguées ayant plusieurs points de contact comprenant un engrenage concave et un engrenage convexe s'engrenant mutuellement par l'intermédiaire d'une mise en contact en plusieurs points. Une surface incurvée d'engrènement de l'engrenage concave et de l'engrenage convexe est une surface incurvée tubulaire, et une courbe de contact formée par des points d'engrènement sur une surface de dent incurvée de l'engrenage concave et une courbe de contact formée par des points d'engrènement sur l'engrenage convexe sont des courbes conjuguées. La paire engrenée est engrenée par mise en contact d'une surface de dent de l'engrenage concave avec une surface de dent de l'engrenage convexe au niveau de plusieurs points en même temps, et des trajectoires de contact des points de contact dans des surfaces de dent respectives sont tous des courbes spatiales lisses.
