【摘要】 以实际使用的一类渐开线变位齿轮轴为例推导了各种坐标系下的渐开线方程,同时列出了在Pro/E中各种坐标系下建立渐开线所对应的参数方程,指出了目前变位齿轮数字化参数建模时存在的问题,详细说明了变位齿轮建模的基本原理和参数化过程。参数化结果与测量结果的一致性说明了方法的可行性,为传动机械参数化设计或建立数字样机提供了必要的参考。更多还原

【Abstract】 A practical example about profile modified gear shaft is made. The involute equations in theory and PRO/E environment in three coordinate systems are deduced. The existent problem of model parameterized building nowadays is introduced. The basic principle of model building and the parameterization process are demonstrated in detail. The result contrast between parameterization and measure illuminates the correctness of the methods. It provides necessary reference for parameterization designing and digital prototype building.更多还原
