乏燃料反应器中的主传动系统为面齿轮传动,其处在高温浓硝酸中工作且要求地震条件下不被损坏,为合理设计其强度,研究了该面齿轮传动的动载特性。阐述了面齿轮啮合原理和特性;基于集中质量法建立了面齿轮传动的动力学模型,考虑了制造与安装误差、时变啮合刚度、齿面腐蚀、地震等因素对其动载特性的影响,推导了面齿轮传动系统的微分方程;利用龙格库塔法求解该微分方程,获得了安装误差、地震和腐蚀等因素作用下面齿轮传动的动载荷,进一步分析了激励因素对动载系数的影响规律。结果表明,腐蚀和地震是引起动载系数大幅增加的关键因素;在所考虑的多因素综合作用下,动载荷小于驱动载荷的2倍。
The main transmission system in a spent fuel reactor is a face gear drive
which works in concentrated nitric acid with high-temperature
and requires not to be damaged under earthquake. To design its strength reasonably
the dynamic performance of the face gear drive is studied. Its meshing principle and characteristics are briefly elaborated. The dynamic model of the face gear drive is established based on the centralized mass method.The influence of factors such as manufacturing errors and misalignments
time-varying meshing stiffness
corrosion on tooth surfaces
earthquakes on the dynamic performance are taken into consideration to deduce the differential equations of the face gear drive. Runge-Kutta method is applied to solve the differential equation
the dynamic loads under excitations of misalignment
earthquake and corrosion are obtained
and the influence law of these excitations on the dynamic load coefficient is further analyzed. The corrosion and earthquake are the key factors that cause significant increase of dynamic load coefficients
the dynamic load caused by the combined action of the considered various factors is less than twice the driving load.
