根据现场检测记录和计算分析,轴悬式牵引电机传动装置在线路上运行时,牵引齿轮总是在偏载情况下工作。随着工况不同,轮齿接触位置偏离程度并不等,当电机前导时,尤为严重。轮齿偏载,齿轮端部产生过大的压力,是造成轮齿过早磨损、早期裂纹、局部点蚀和断齿的重要原因。为此,改善轮齿偏载,乃是 According to the on-site test records and calculation analysis, when the shaft-suspended traction motor drive runs on the line, the traction gear always works under partial load. As the working conditions are different, the gear contact position deviation does not wait, when the motor leads, especially serious. Gear tooth partial load, the gear end of the excessive pressure is caused by tooth premature wear, early cracks, local pitting and broken teeth important reason. To this end, improving gear partial load, but yes
