齿轮径向跳动误差源于齿轮加工安装偏心引起的原理性误差,实际测量中由于齿轮芯轴中心孔偏心,会使测量结果产生系统误差,需予以消除.通过对实际的齿轮进行测量,分析得出当齿轮安装回转中心与芯轴中心一致时,齿轮径向跳动误差与芯轴的径向跳动误差产生同向误差;反之,产生反向误差.将齿轮芯轴的径向跳动误差作为修正值,对齿轮径向跳动误差测量值进行补偿,即可获得齿轮径向跳动误差的真实值,可以实现对齿轮精度的正确评定.

公差对机床的精度设计具有指导意义,目前机床设计大多仍依赖于传统经验。为揭示机床零部件公差与机床几何误差源参数间的映射关系,本文以数控外圆磨床为例,构建了零部件公差与其表面几何形貌误差的关系模型,依据磨床零部件公差的概念及其运动规律,推导出零部件几何误差形貌与几何误差源参数的内在联系,建立了磨床关键零部件公差与机床几何误差源参数间的关系模型,为数控外圆磨床运行精度预报及关键零部件的公差参数优化分配奠定理论基础。
