【摘要】：提出了一種弧線等高齒高減速比準(zhǔn)雙曲面(HRH)齒輪,探討了HRH齒輪節(jié)錐的演變以及弧線等高輪齒在齒高和齒厚方向上的演化過程。分析了HRH齒輪幾何特性的演變過程及其涉及的關(guān)鍵因素,給出了弧線等高齒HRH齒輪節(jié)錐設(shè)計的優(yōu)化方法。利用大輪齒面幾何和嚙合方程推導(dǎo)出共軛小輪的齒面方程,求出離散齒面點坐標(biāo)。對大小輪輪齒實體進行了三維建模仿真,并與所加工的實體模型進行了對比分析。證明了所提出的弧線等高齒HRH齒輪在理論和實踐上的可行性。
[Abstract]:This paper presents a kind of hypoid HRH gear with arc contour tooth height and deceleration ratio. The evolution of the pitch bevel of HRH gear and the evolution process of arc contour gear tooth in the direction of tooth height and tooth thickness are discussed. The evolution process of geometric characteristics of HRH gears and the key factors involved are analyzed. The optimization method for the design of HRH gear pitch bevel with arc isodontic teeth is presented. The tooth surface equation of the conjugate small wheel is derived by using the geometry and meshing equation of the large gear tooth surface and the coordinates of the discrete tooth surface point are obtained. The 3D modeling and simulation of the large and small gear teeth are carried out and compared with the machined solid model. The theoretical and practical feasibility of the proposed arc isodontic HRH gear is proved.
