中文摘要:
提出一种能够同时传递相交轴间的转动和移动的端曲面齿轮副。根据齿轮传动有关理论,设计了偏心端曲面齿轮副传动比,推导了偏心端曲面齿轮副节曲线。通过齿轮啮合原理,建立了该齿轮副的啮合方程和齿面方程,研究了偏心端曲面齿轮副压力角的变化规律,并使用SolidWorks的API接口进行二次开发,实现了偏心端曲面齿轮副的三维建模。分析结果表明偏心端曲面齿轮副设计方法能够实现更大的传动比和压力角,满足更多的潜在工程应用。
English Summary:
A kind of curved-face gear pair was proposed to transfer rotation and movement of the intersecting axes. According to the theories of gear transmission, the transmission ratio of eccentric curved-face gear pair was designed, and the pitch curve of eccentric curved-face gear pair was deduced. Through the principle of gear engagement, the meshing equation and tooth surface equation were built, and the change law of pressure angle of gear pair was studied, besides, a 3D model of eccentric curved-face gear pair was built with API in SolidWorks. The results validate the correctness of the design method of eccentric curved-face gear pair, and show that it can realize larger transmission ratio and pressure angle, and the gear pair can meet more potential engineering application.
