滚动轴承的安全检查 | 2013-3-26 8:02:00
滚动轴承的安全检查
1)轴承元件应预防出现裂纹、脱落、伤痕、锈斑、点蚀或变色等。保持架应完整无变形。转动灵活,无异响。
2)不得采取在轴颈上打麻面或加垫的办法来处理该项配合出现的间隙。
3)、滚动轴承径向磨损间隙应预防超过规定。
4)安装圆锥滚柱轴承时,必须用垫调整轴向间隙,使其符合设计图纸要求。
5)装配轴承轴颈的表面粗糙度Ra≤0.8μm ,轴承座孔的表面粗糙度Ra≤1.6μm。
6)轴承润滑的油量要适当,油质应符合规定,轴承座不得漏油。
7)装配时应将轴承上注有字样的端面朝外,轴承必须紧贴在轴肩或间隔套上,不得有间隙(可调整的轴承例外)。
8)滚针轴承的表面不得有划痕或退火现象。拆卸时不得混套,应原套装在原轴上。同一组滚针的直径差不得超过0.005mm。滚针直径磨损量不得超过0.02mm。
9) 轴承在运行中应无异常响声,运行中的温度:滚动轴承不得超过75oC;滑动轴承不得超过65 oC,或按厂家技术文件执行。
