【摘要】：线齿轮机构在啮合的过程中,法向侧隙影响其在正转至反转的过渡。在空间曲线啮合理论的基础上,研究了适合正反转的空间螺旋曲面齿轮副。以螺旋线为中心线,研究截面为圆时其曲面方程,并构建此曲面为主动轮齿面,分析其啮合时主动齿面上的正反转接触线。以此正反转接触线为基准,计算矩形截面的从动轮曲面方程,由此构建从动轮曲面,使其能包含主动齿面的圆截面。研究空间螺旋曲面齿轮副的运动学性能,结果表明,此方法构建的齿轮副,在正反转时能够完整过渡而没有大的法向侧隙,能够满足传动的需求。
[Abstract]:In line gear meshing process, normal backlash is to reverse its influence on transition. Based on the theory of space curve mesh, the space for reversing gear helical surface. With spiral line as the center line, the research section is round the surface equation, and construct the surface active tooth surface, and the contact line switching analysis when meshing tooth surface. The active positive and negative switching contact line as the benchmark, calculation of rectangular cross section from the wheel surface equation, thus constructed from the wheel surface, which can contain active tooth surface of circular cross section. The results showed that the kinematics, space research of spiral surface of the gear pair. This method constructs the gear pair, in rotation when complete transition without the normal backlash, which can meet the transmission requirements.
