摘　　要：基于CATIA软件,对渐开线非标准圆柱齿轮副进行全参数化精确建模的方法进行了研究。所述的非标准圆柱齿轮主要是指齿轮参数的非标准化而非结构上的非标准,重点探讨了非标圆柱斜齿轮建模参数的选取与建立,部分参数需要通过齿轮副或配对齿轮的参数来进行定义,如齿根高、变位等。基于精准参数建模需要,将齿厚、齿顶、齿根等公差纳入相应的建模方程或公式,以实现自动生成精准数模,可以直接用于进一步的功能、可靠性仿真以及有限元设计分析和优化,并且数模的变更或重新设计仅需修改相关的参数就能实现,大大提高了齿轮数模设计效率。Based on the CATIA software,the method of fully parameterized accurate modeling of involute non-standard cylindrical gear pairs was studied.The non-standard cylindrical gear mainly referred to the non-standard parameters rather than non-standard gear structural.The selection and establishment of modeling parameters of non-standard cylindrical helical gears were discussed.Some parameters need to be defined by gear pair or pair gear parameters,such as tooth root height,displacement and so on.Based on the need of accurate parameter modeling,the tolerances of tooth thickness,tooth top and tooth root are incorporated into the corresponding modeling equations or formulas to realize the automatic generation of accurate digital models,which can be directly used for further function and reliability simulation and finite element design analysis and optimization,greatly improve the gear digital-analog design efficiency.
