摘要
以采煤机摇臂输出轴轴承为研究对象,对轴承进行受力分析并计算出轴承所承受的载荷。使用Hertz接触理论公式,计算出最大接触应力,利用ABAQUS有限元软件对轴承进行仿真得到最大应力,结合接触疲劳寿命计算,求得轴承的疲劳寿命值为2.6 a,为轴承的维护和检修提供了参考依据。
Taking the output shaft bearing of shearer rocker arm as the research object, the force of the bearing was analyzed and the load borne by the bearing was calculated. Using Hertz contact theory formula, the maximum contact stress was calculated, the ABAQUS finite element software was used to simulate the bearing to get the maximum stress, combined with contact fatigue life calculation, the fatigue life value of bearing is 2.6 years. This provides a reference for the maintenance and overhaul of bearings.
