交叉滚子轴承在经过长时间使用之后,会因为磨损出现各种情况,影响轴承的使用,其中轴承在使用过程出现异响就是一种常见的情形,导致轴承出现异响的原因也有很多,不同的形成原因有不同的解决方法,下面给大家介绍下交叉滚子轴承异响的原因及解决方法。

一、交叉滚子轴承异响的原因

01 轴承磨损

轴承的内外滚道有磕碰、凹痕或者严重的故障时会导致交叉滚子轴承出现异响,滚动体的表面撞击、刮擦等缺陷也会导致交叉滚子轴承出现平滑的清脆响声。轴承在长时间的使用之后,很容易出现磨损,导致轴承与轴承和轴的啮合关系发生损坏,使得轴发生偏差导致出现周期性的振动脉冲。

02 轴间隙过小

交叉滚子轴承的轴向间隙一般是要求转动间隙越小越好,但是如果滚道内的滚子挤得过紧,轴向间隙过小,导致摩擦的阻力增加,在滚动体和保持架兜孔之间出现剧烈的碰撞,从而出现异响。

03 进入异物杂物

像是一些杂质、铁屑等异物进入到轴承的滚道运转区,会和滚道内的滚子发生剧烈摩擦,这时即使是很小的灰尘也会导致轴承出现周期性或非周期性的振动脉冲,导致轴承在运转过程中出现异响。

04 润滑油性能不足

交叉滚子轴承所使用的润滑油性能比较差或者是润滑油质量较差会导致轴承在使用过程中出现异响。轴承密封不当导致机油或者油脂泄漏,滚动体和保持架的凹槽间发生摩擦,以及滚动体在运行过程中由于研磨润滑剂而导致出现振动脉冲使得轴承出现异响。

二、交叉滚子轴承异响的解决方法

01 磨损后及时更换

交叉滚子轴承在出现异响之后要对轴承的表面进行检查,看是否有碰撞、破损的现象,如果轴承有问题则需要及时地进行更换,因为轴承中出现的微小问题也会对轴承的运转产生影响。

02 调整间隙

交叉滚子轴承的间隙过小会使它的附加力矩变大,所以在出现异常噪音时,也可以先检查是否是间隙太小,尝试调节间隙。

03 更换润滑油

润滑油的选用对轴承的性能有很大的影响,所以对于润滑油的选用要多加重视,润滑油对轴承转速、载荷噪声、磨损、腐蚀等都有很大的影响。

在轴承运转使用过程中出现异响是很常见的一种情况,要仔细分析其异响原因,并找到相应的方法进行解决。
