圆柱滚子轴承常见的异常损伤解决措施原理

日期:2019-03-05 11:57 作者:ina 阅读:
1) SUNTHAI轴承运转时若出现有节奏的敲击声或撞击声,可能是由于圆柱滚子轴承滚道剥落、有压痕、或其他零件安装不当造成;
2)发现SUNTHAI轴承有 ;咕碌、咕碌 ;的声音,可能是由于轴承密封不严、润滑油不干净、轴承游隙太大造成的;
3)发现轴承有 ;吱咛、吱咛 ;的尖叫声音,可能是由于润滑剂干涸或缺乏润滑剂造成的;
4)若发现轴承有 ;沙沙沙 ;的响声,可能是圆柱滚子轴承未清洗干净,内部混有磨屑、砂粒、灰尘等杂物所致;
5)轴承内圈受热过度膨胀,轴承及密封件与相关零件发生摩擦;
6)安装SUNTHAI轴承时,因敲打轴承或其他零件,引起轴承变形;
7)轴承的紧定套上得过紧或松动;
8)轴承箱的尺寸过大(包括使用中变大),引起IKO轴承外圈在轴承座中转动……等等,都有可能使轴承产生噪声和异常声。引起圆柱滚子轴承振动的原因,基本上与造成轴承噪声和异常声的原因相同,两者之间有很强的相关性。但不在音频范围内的振动频率,则不会引起噪声和异常声。
轴承的辗轧声及其控制方法辗轧声是圆柱滚子轴承在所有场合都可能发生的刺耳的金属摩擦声,大多发生在脂润滑的较大型号轴承中,而在基油性能劣化的润滑脂中更易发生,在油润滑时几乎不发生。nsk轴承代理商依按摩擦性质而定,直线运动导轨可以分为滑动摩擦导轨、滚动摩擦导轨、弹性摩擦导轨、流体摩擦导轨等种类。nsk轴承是在模具的开模动作中能够按垂直于开合模方向或与开合模方向成一定角度滑动的模具组件。 当产品结构使得模具在不采用滑块不能正常脱模的情况下就得使用滑块了。此外,在冬季时较易发生,当承受纯径向负荷时,在径向游隙大的场合容易发生,并且随型号大小的不同,在某一特定的转速范围内容易发生,既会连续发生又会间歇出现。对外圈滚道采取特殊的加工方法可以防止辗轧声的出现,必要时可选用这种高温轴承,或适当减少轴承的径向游隙,使用性能优良的润滑脂和提高与圆柱滚子轴承相配机件的刚性。
 
  (1)选择低噪声轴承;这就取决于买高质量的圆柱滚子轴承,一般好的IKO轴承都是用高材料的钢制成,具有高密度,高耐性的特点;
 
  (2)从轴承应用环节上设法消除噪声,就是在环节上面加润滑油脂,一定要选好润滑材料,可以起到事半功倍的效果;
 
  (3)避免与主机发生共振,避开共振敏感转速;此点需要专业人员的安装调试,可以避免共振问题;
 
  (4)如果在其他方法无效时,就采取隔音和消声的附加措施,安装一些声音控制设备等等。日本nsk轴承轴承工业飞速发展,轴承品种由少到多,产品质量和技术水平从低到高,行业规模从小到大,已经形成了产品门类基本齐全、生产布局较为合理的专业生产体系。
