摘要

通过给定齿面方程及数据点,基于UG三维软件建立塑料蜗杆与钢质斜齿轮的基本啮合模型;采用Hyper Mesh软件进行模型网格划分、约束施加和接触条件设定等前处理,运用有限元方法动态对比分析负载状态下塑料蜗杆与钢质斜齿轮、钢质蜗杆与钢质斜齿轮的两齿-单齿-两齿接触齿面应力变化及接触状态变化规律;分别采用滚齿、注塑和车削方法完成钢质斜齿轮、塑料蜗杆和钢质蜗杆的样件试制,并基于微型传动实验平台进行齿面磨损对比测试。结果表明,塑料蜗杆啮合过程中接触应力低、波动小,且具有更好的耐磨性。

Abstract

The 3 D model of worm and helical gear is established based on UG by the equation of tooth surface and the data point. On the basis of Hyper Mesh,the pretreatment of the finite element model including mesh generation,applying constrains,setting contact condition,etc. is carried out. By using FEM,the analysis of dynamic contact from the double teeth-meshing to the single teeth-meshing and then to the double teeth-meshing is carried out to simulate the changes of the tooth contact stress and shape under the actual working conditions and to find the characteristics of engagement about plastic worm and steel helical gear,steel worm and steel helical gear. The samples including steel helical gear,plastic worm and steel worm are machined by hobbing,injection and turning respectively,then used to wear test on the basic of the micro-transmission test platform,the results show that the contact stress and fluctuation in the meshing process of plastic worm is small,and it has the better wear resistance.
