圆锥滚子轴承的作用和使用事项

The Role and Use of Tapered Roller Bearings

圆锥滚子轴承主要承受以径向为主的径、轴向联合载荷。轴承承载能力取决于外圈的滚道角度,角度越大承载能力越大。该类轴承属分离型轴承,根据轴承中滚动体的列数分为单列、双列和四列圆锥滚子轴承。单列圆锥滚子轴承游隙需用户在安装时调整;双列和四列圆锥滚子轴承游隙已在产品出厂时依据用户要求给定,不须用户调整。

Tapered roller bearings are to bear radial primarily diameter, the axial joint load. Rolling bearing capacity depends on the angle of the outer ring, the bearing capacity of the larger angle. This kind of bearing is separable bearings, roller bearings according to the number of columns is divided into single row, double row and four row circular cone roller bearings separately. Tapered roller bearing clearance adjustment to users in the installation; double row and four row tapered roller bearing clearance has been in the factory according to user requirements given, the user does not have to adjust.
圆锥滚子轴承有圆锥形内圈和外圈滚道,圆锥滚子排列在两者之间。所有圆锥表面的投影线都在轴承轴线的同一点相聚。这种设计使圆锥滚子轴承特别适合承受复合(径向与轴向)负荷。轴承的轴向负荷能力大部分是由接触角α决定的;α角度越大,轴向负荷能力就越高。角度大小用计算系数e来表示;e值越大,接触角度越大,轴承承受轴向负荷的适用性就越大。

Tapered roller bearings have conical inner ring and outer ring raceway. Tapered rollers are arranged in between. Projection lines on all conical surfaces converge at the same point in the bearing axis. This design makes tapered roller bearings particularly suitable for bearing composite (radial and axial). Load. The axial load capacity of the bearing is mostly determined by the contact angle α; The greater the α angle, the higher the axial load capacity. The greater the e value, the greater the contact angle, the greater the applicability of bearing to axial load.
圆锥滚子轴承通常是分离型的,即由带滚子与保持架组件的内圈组成的圆锥内圈组件可以与圆锥外圈(外圈)分开安装。

Tapered roller bearings are usually of separate type, i.e. conical inner ring assemblies consisting of inner rings with roller and cage assemblies can be mounted separately from conical outer rings (outer rings).
圆锥滚子轴承广泛用于汽车、轧机、矿山、冶金、塑料机械等行业。

Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
圆锥滚子轴承正在装置进程中涌现创痕的次要缘由是:轴承正在装置、组装时涌现内圈、外圈歪斜;或者许是正在装置和组装的进程中的涌现冲锋陷阵负荷,最终形成轴承涌现创痕。
正在装置圆锥滚子轴承时要依照工作规范停止,要不会形成许多成绩,如装置的形式或者办法没有当,则会形成轴承的滚道面及骨碌面上形成轴承涌现线状的创痕。深沟球轴承的装置间接反应着轴承运用时的精密度、寿数和功能。

The main reason is that the emergence of tapered roller bearing device in the process are: bearing device, when assembling the emergence of the inner ring, the outer ring of skew; or perhaps the emergence of load device and assembling charge into the enemy ranks are in the process of the final formation. That is the emergence of the bearing device conical roller bearing should be in accordance with the job specification to stop, not many results, such as to form or not when the device, will emerge the scar formation of linear bearing raceway surface and rolling bearing surface. Device of deep groove ball bearing with bearing using the indirect reaction when precision, life and function.
圆锥滚子轴承质量等各方面虽然都比较好,但滚动轴承是精密部件,其使用也须相应地慎重进行。无论使用多么高性能的轴承,如果使用不当,则不会得到预期的高性能。有关轴承的使用注意事项有以下几条: 

Although the quality of tapered roller bearings is good, the rolling bearings are precision parts, and their use should be carefully carried out accordingly. No matter how high performance bearings are used, if they are not used properly. The expected high performance will not be obtained. The following considerations are noted for the use of bearings:
(1)、保持圆锥滚子轴承及其周围清洁。 
    即使是眼睛看不到的小尘埃,也会给轴承带来坏影响。所以,要保持周围清洁,使尘埃不致侵入轴承。 

Keep the tapered roller bearings and their surroundings clean. Even small dust that is invisible to the eyes can have a bad effect on the bearings. So keep the surroundings clean so that the dust does not intrude into the bearings.
(2)、小心谨慎地使用。 
    在使用中给与圆锥滚子轴承强烈冲击,会产生伤痕及压痕,成为事故的原因。严重的情况下,会裂缝、断裂,所以必须注意。 

Give taper roller bearing a strong impact in use, will produce scars and indentation, become the cause of the accident. In serious cases, will crack, fracture, so we must pay attention to.
(3)、使用恰当的操作工具。 
    避免以现有的工具代替,必须使用恰当的工具。 

Use the right operating tools. Avoid using existing tools. Use the right tools.
(4)、要注意圆锥滚子轴承的锈蚀。 

Attention should be paid to the corrosion of tapered roller bearings.

操作轴承时,手上的汗会成为生锈的原因。要注意用干净的手操作,最好尽量带上手套。
圆锥滚子轴承利用听觉来辨识不规则的运转是一种很普通的方法,例子如借助电子式听诊器来查觉某一零件的不正常噪音是有经验操作员使用。轴承若是处于良好的运转状况会发出低的呜呜声音,若是发出尖锐的嘶嘶音圆锥滚子轴承、吱吱音及其它不规则的声音、通常表示轴承处于不良的运转状况。

When operating the bearing, the sweat on the hand can be the cause of rust. Use clean hands and wear gloves as far as possible. Tapered roller bearings use hearing to identify irregular movement is a very common method. For example, using an electronic stethoscope to detect a zero piece of abnormal noise is used by an experienced operator. Bearings in good working condition emit a low whine. A sharp hissing tapered roller bearing, squeak and other irregular sounds usually indicate that the bearing is in bad working condition.
1、瓦面腐蚀:光谱分析发现有色金属元素浓度异常;铁谱中出现了许多有色金属成分的亚微米级磨损颗粒;润滑油水分超标、酸值超标。

1, tile surface corrosion: spectra of non-ferrous metal element concentration anomaly; there are many nonferrous metal components of sub micron particle wear ferrography; oil water exceed the standard, exceed the standard value.
2、轴颈表面拉伤:铁谱中有铁系切削磨粒或黑色氧化物颗粒,金属表面存在回火色。

2, the journal surface strain spectrum: iron iron line cutting abrasive or black metal oxide particles, temper the surface.
3、轴颈表面腐蚀:光谱分析发现铁元素浓度异常,铁谱中有许多铁成分的亚微米颗粒,润滑油水分超标或酸值超标。

3, shaft neck surface corrosion: spectral analysis of iron concentrations found abnormal, submicron particles have many iron components of iron in the spectrum of lubricating oil or water exceed the standard.
4、表面拉伤:铁谱中发现有切削磨粒,磨粒成分为有色金属。

4 value exceed the standard, the surface strain: iron spectrum is found in cutting abrasive, abrasive composition for nonferrous metals.
5、瓦背微动磨损:光谱分析发现铁浓度异常,铁谱中有许多铁成分亚微米磨损颗粒,润滑油水分及酸值异常。在液体润滑条件下,滑动表面被润滑油分开而不发生直接接触,还可以大大减小摩擦损失和表面磨损,油膜还具有一定的吸振能力

5, tile back fretting wear the spectral analysis showed that iron The concentration is abnormal, and there are many submicron wear particles of iron in the iron spectrum, and the water and acid value of the lubricating oil are abnormal. Under the condition of liquid lubrication , the sliding surface is separated from the lubricating oil without direct contact , the friction loss and the surface abrasion can be greatly reduced , and the oil film also has certain vibration absorption capacity
尖锐的吱吱噪音可能是由于不适当的润滑所造成的。不适当的轴承间隙也会造成金属声。圆锥滚子轴承外圈轨道上的凹痕会引起振动,并造成平顺清脆的声音,若是由于安装时所造成的敲击伤痕也会产生噪音,此噪音会随著轴承转速的高低而不同。若是有间歇性的噪音,则表示滚动件可能受损,圆锥滚子轴承此声音是发生在当受损表面被辗压过时,轴承内若有污染物常会引起嘶嘶音,严重的轴承损坏会产生不规则并且巨大的噪音。

A sharp creak noise may be due to inadequate lubrication caused. The bearing clearance can also cause inappropriate metallic sound. Dent taper roller bearings on the track will cause vibration, resulting in smooth crisp sound, if the installation of the percussion scars will produce noise, the noise will follow bearing speed vary. If intermittent noise, said rolling element may be damaged, tapered roller bearings, this sound is when the damage occurred in the surface is rolled out, bearing if hissing sound pollution often caused serious damage to the bearing will produce irregular and loud noise.
轴承损坏固然可藉由听力来查觉,但是通常此时已经到了轴承必须马上被更换不可。所以,较好的方法例如使用如电子式状况监测仪器,圆锥滚子轴承预先疹断轴承的运转情况。

Bearing damage can be detected by hearing, but usually the bearing must be replaced immediately by this time. Therefore, better methods such as using electronic condition monitoring instruments. The operation of tapered roller bearings is broken in advance.
