摆动活齿传动强度的模糊可靠性设计

The Fuzzy Reliability Design of Strength for Swing Movable Teeth Drive

摆动活齿传动是一种新型行星传动，本文进行了受力分析，建立了各主要零件的应力计算公式，分析了应力的随机性和许用应力的模糊性，提出了这种传动的模糊可靠性设计方法，并给出了应用实例。

Swing movable teeth transmission is a new type of small teeth difference planetary gear drive. The method of force analysis is presented, and the calculation formulae of stress for various main parts are given in this paper. The randomness of working stress and the fuzziness of allowable stress are discussed. The approach of fuzzy reliability strength design for the drive is proposed, and a numerical example is given for illustration.
