摘要
为研究变速器滚动轴承的动态可靠性,以 5T136 变速器为原型,应用ANSYS软件建立深沟球滚动轴承的有限元模型.对滚动轴承进行模态分析,发现前 6 阶发生共振的可能性很小;经过静力学有限元分析,发现轴承最大等效应力发生在滚动体,为 233.36 MPa,最大变形发生在内圈,为 0.003 311 1 mm;使用 6 Sigma模块进行动态可靠性分析,杨氏模量大于 225.87 MPa的可靠度为 99.993%,轴承运行安全可靠.
Abstract
To study the dynamic reliability of the rolling bearings in the 5T136 transmission prototype,a finite element model of the deep groove ball bearing was established using ANSYS software.A modal analysis was conducted on the rolling bearing,and the possibility of resonance occurring within the first 6 modes was found to be very low.A static finite element analysis was performed,revealing that the maximum equivalent stress in the bearing occurred on the rolling elements and was measured at 233.36 MPa,while the maximum deformation occurred on the inner ring and amounted to 0.003 311 1 mm.A dynamic reliability analysis was carried out using the 6 Sigma module,which indicated a reliability of 99.993%that the Young's modulus would be more than 225.87 MPa,and the bearing can operate safely and reliably.
