摘要

为了研究塑料斜齿轮与钢制蜗杆在传动过程中齿面的受力情况,建立了考虑齿间载荷分配的塑料斜齿轮与钢制蜗杆啮合副力学模型,并利用齿轮啮合过程中的变形协调关系,计算得到了塑料斜齿轮齿面接触点啮合力在连续啮合过程中的变化规律。同时也利用ANSYS Workbench有限元软件对塑料斜齿轮与钢制蜗杆的啮合力进行了仿真分析,分析结果显示采用本文方法计算结果与有限元仿真结果吻合良好,验证了本文方法的合理有效。研究表明,塑料斜齿轮齿面在正常啮合过程中的最大啮合力出现在靠近齿根处的少齿啮合区,塑料斜齿轮在此处容易发生磨损和疲劳破坏。所提方法实现了对塑料斜齿轮与钢制蜗杆啮合力的快速计算,可为工程中齿轮设计以及提高齿轮承载能力提供一定的参考。

Abstract

In order to investigate the meshing force of the tooth surface of the plastic helical gear and the steel worm in the transmission process,the mechanical model of the meshing pair of plastic helical gear and steel worm is established by considering the load distribution between the meshing teeth. By using the deformation compatibility in the gear meshing process,the variation of the contact point meshing force of the tooth surface of the plastic helical gear in the continuous meshing process is calculated. And the meshing force of the plastic helical gear and the steel worm is analyzed with the ANSYS Workbench finite element software. The calculation examples show that the results obtained by the method are in good agreement with the simulation results of the finite element method,which proves that the proposed method is reasonable and effective. The research shows that the maximum meshing force of plastic helical gears in the normal meshing process appears in the small tooth meshing area near the tooth root,so the plastic helical gears are prone to wear and fatigue damage.The fast calculation of meshing force between plastic helical gear and steel worm is realized by the proposed method,some references for gear design and gear loading capacity improved in engineering can be provided.
