今天为大家简单介绍链轮轴组维修检测的基本标准。

一、拆解

清洗链轮表面,清除煤渣;

将链轮垂直吊起,松开上端的油塞,将链轮吊到废油池,松开下端的放油塞,放出废油;

将链轮垂直立起,拆下密封盖,再用200吨拔轮器将链轮体,轴承座拆解等。

二、清洗检测

链轮轴的检测:链轮轴无拉伤,裂纹,碰伤,弯曲和严重磨损,传动配合花键应无扭曲、无断裂、无变形、无严重磨损和破碎,链轮轴两端装配轴承外无不得有拉伤。

链轮体:链轮齿不得有破碎现象,磨损不得过于严重,链轮内孔花键无破碎,裂纹和扭曲变形。

轴承座:轴承座安装摩擦密封部位不得破碎,磨损不能过大,装配轴承内孔不得有拉伤和严重磨损。

距离套:主要是控制轴承轴向窜动的部件,所以它的长度磨损不得超过0.2mm(即:端面磨损),不得有裂纹。

浮封座:浮封腔外圆和端面不得有锈蚀、磨损、破碎等现象。

轴承:检测轴承滚珠、滚道无点蚀、拉伤、破损、保持架体完好,转动灵活,轴承游隙及尺寸符合国标。

密封:更换全套密封。
