基于理论概率法的齿轮传动孔系精度设计

The Precision Design of the Gear-driven Hole's System Based on Theoretical Probabilistic Method

依据机械加工工艺和装配过程的经典误差理论及其几何参数分布规律，运用理论概率法的原理和方法，提出机械精度设计的数学模型，提高了工程设计水平。

Accordign to the classical error theory and its geometrical parmeter's distribution of the mechanicl machining and part as- sembling,this paper handles the principles and ways of theoretical probabilistic method to put forward the mathematical model model of the me- chanical precision design,it improves the engineering design levels.
