摘要

针对某钢厂210 t转炉倾动机构在启动过程中存在抱闸开启不同步现象,为研究此工况下接触冲击对齿轮强度的影响,在Pro/E中建立减速器末级齿轮的几何实体模型,将其导入Hyper Mesh有限元前处理软件建立有限元求解模型,利用显式动力学求解器LS-DYNA进行求解。结果表明,在齿轮零间隙接触的情况下,抱闸不同步打开使滞后启动小齿轮所受冲击应力远小于其他3个小齿轮。同时,验证了齿轮接触冲击应力随着齿轮间速度差的增加而增大,齿轮最大冲击应力发生在齿宽中部齿根位置处。

Abstract

Aiming at the brakes open out of sync phenomenon of 210 t converter tilting mechanism in a steel plant,to study the influence of contact-impact on the gear strength under this working condition,the geometry entity model of the reducer is set up in Pro / E,and it is imported into the software of Hyper Mesh to built the finite element solving model,and the solving is carried out by using the explicit dynamics solver LS-DYNA.According to the results,a conclusion can be drawn that the impact stress of the pinion starting later is far less than that of three other pinions,when the gears contact without clearance and brakes open out of sync.At the same time,the result verifies the conclusion that the gear contact impact stress increases with increasing of the velocity difference between the gears and the maximum impact stress of gear occurs in tooth root in the middle of tooth width.
