| 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. |
