摘要: 附加径向运动方式的斜齿轮双面磨削方法具有小批量多品种加工的特性与机构可靠的优点,但在加工时会出现无法避免的齿面扭曲现象,导致加工齿面与理论齿面存在原理性误差,针对该现象对斜齿轮性能的影响进行了量化研究。以数值方法计算得到双面磨削方法的误差齿面模型,将该误差齿面与理论齿面进行对比,采用齿面接触分析方法(TCA)计算获得不同齿面下的传动误差和接触斑点。结果表明,齿形扭曲对左齿面性能影响较小,左齿面可基本实现理论修形效果,齿向扭曲现象导致右齿面性能发生了明显劣化;合适的修形方式与轴交角可以使左右齿面传动误差差异缩小在15%左右。

Abstract: The double-sided grinding method of helical gears with additional radial motion had the advantages of small-lot and multi-variety machining and reliable mechanisms, but the unavoidable tooth surface distortion phenomenon occured during machining, resulting in the principle errors between the machined tooth surface and the theoretical tooth surface, and the impacts of this phenomenon on the performance of helical gears were quantified. The error tooth surface model of the double-sided grinding method was calculated numerically, and the error tooth surface was compared with the theoretical tooth surface; the transmission errors and contact spots under different tooth surfaces were calculated by the tooth surface contact analysis (TCA) method. The results show that the distortion of tooth shape has less influences on the performance of the left tooth faces, and the left tooth face may basically achieve the theoretical reshaping effect, while the tooth distortion phenomenon causes significant deterioration of the right tooth face performance; the appropriate reshaping method and shaft intersection angle may reduce the transmission error difference between the left and right tooth faces to about 15%.

Key words: form grinding, topological modification, transmission error, contact spot
