摘要:

研究了电子齿轮箱的实现原理及其在数控系统中的实现方法,从几何角度分析了齿轮展成法加工误差产生的原因,并推导出电子展成误差的计算公式。建立了电子齿轮箱仿真模型,通过对模型的仿真分析和优化,计算得到了该控制模型的电子展成误差。将该模型用于六轴数控系统实验平台,在空载条件下分析了电子展成误差。最后将自主研发的带电子齿轮箱的滚齿数控系统应用于YS3118数控滚齿机,通过齿轮加工及检测证明了该电子齿轮箱的控制精度满足齿轮的加工要求。

Abstract:

The implementation principles of EGB and the EGB realization method in CNC system were first studied herein. Then, the reasons of gear generating errors were discussed from the point of geometric view, and the instantaneous EGB control error calculation formula was deduced. In addition, the simulation models of EGB were built, the control errors were obtained by simulation analysis and optimization, and the optimization model was applied into the CNC system of six axis experimental platform. Then, the errors were analyzed under the no-load conditions. Finally, the CNC system with EGB was applied in YS3118 CNC gear hobbing machine. The gear machining and measuring results show that the EGB control precision can satisfy the demands of gear machining.

Key words: electronic gearbox(EGB), gear-hobbing, generating, feedforward
