摘要
运用ANSYS Workbench软件对楼道升降机的齿轮齿条结构进行静力学分析,先研究楼梯非转弯处的直线齿条,将其齿根处抗折断强度的理论值与ANSYS软件有限元仿真结果进行对比,得出符合此工况的齿轮齿条模型加载方式,再将此方式应用到曲线齿条。结果表明:在楼道非转弯处,直线齿条齿根处的最大应力值与理论计算值基本吻合,且大于齿轮齿根处的最大应力值;在楼道转弯处,不同折弯半径的齿条与齿轮啮合时,齿轮和齿条的齿根处最大应力值呈现先增加后减小的趋势,最终在齿条折弯半径达到500 mm时,齿轮和齿条的齿根处最大应力达到最大,分别为204.19 MPa、400.46 MPa。
When the static analysis of the gear and rack structure of the corridor elevator is carried out by using ANSYS Workbench software, the linear rack at the non turning part of the stairs is usually studied first, and the theoretical value of the breaking strength at the root is compared with the finite element simulation results of ANSYS software, so as to obtain the loading mode of the gear and rack model in line with this working condition, and then this mode is applied to the curved rack. The results show that at the non turning part of the corridor, the maximum stress at the of the linear rack is basically consistent with the theoretical value, and is greater than the maximum stress at the root of the gear. At the corner of the corridor, when the racks with different bending radius mesh with the gears, the maximum stress at the root of the gear and rack increases first and then decreases. Finally, when the bending radius of the rack reaches 500 mm, the maximum stress at the root of the gear and rack reaches the maximum, which are 204.19 MPa and 400.46 MPa respectively.
