智能燃气表电机阀用超越离合器结构应力分析及改进
|
摘要
基于赫兹理论以及有限元分析软件ANSYS Workbench对新型智能燃气表电机阀中使用的超越离合器进行静力学分析,并根据分析结果对滚柱母线进行鼓形修整。改进结果表明,鼓形量在0.010 mm时,滚柱表面所受到的最大应力从10.3 MPa降低至7.8 MPa,应力减少了24%,提高了超越离合器的使用寿命。此外,改进设计对改善超越离合器和智能燃气表的可靠性及稳定性具有一定的指导意义。
By using the Hertz theory and the finite element analysis software named ANSYS Workbench,a static analysis is conducted for the overrunning clutch used in a new type of motor valve of the intelligent gas meter,and drum modification of the roller generatrix is conducted according to the analysis results. The improvement results show that the drum amount at 0. 010 mm,the maximum equivalent stress of roller decreased by 24% from 10. 3 MPa to 7. 8 MPa,so that the service life of overrunning clutch is improved. The improving design results could have a certain guiding significance on the working reliability and stability for the overrunning clutch.
