负荷轴承负荷的大小、方向和性质[轴承的负荷能力用基本额定负荷表示,其数值载于FAG轴承尺寸表] 轴承负荷富于变化,如负荷的大小、是否只有径向负荷、轴向负荷是单向还是双向、振动或冲击的程度等等。在考虑了这些因素后,再来选择最为合适的轴承类型。

Load bearing load size, orientation, and the nature of [the load carrying capacity of the bearings is expressed in basic rated load, the values contained in the FAG bearing size table] bearing load richly varied, such as whether the size of the load, only the radial loads, axial loads are one-way or two-way, the level of vibration or shock, and so on. After considering these factors, and then to select the most appropriate type of bearing.

一般来说,相同内径的轴承的径向负荷能力按下列顺序递增:深沟球轴承<角接触球轴承<圆柱滚子轴承<圆锥滚子轴承<调心滚子轴承

In General, the same bore diameter of bearing radial load capacity increases in the following order: deep groove ball bearings < angular contact ball bearings < cylindrical roller bearings < tapered roller bearing < spherical roller bearings

1、轴承保养:为了尽可能长时间地以良好状态维持轴承本来的性能,须保养、检修、以求防事故于未然,确保运转的可靠性,提高生产性、经济性。

保养最好相应机械运转条件的作业标准,定期进行。内容包括监视运转状态、补充或更换润滑剂、定期拆卸的检查。运转中的检修事项,有单向轴承的旋转音、振动、温度、润滑剂的状态等等。

1, axle bearing maintenance for bearings in good condition as long as possible to maintain original performance, maintenance, overhaul, in order to prevent accidents, it is imperative to ensure operational reliability, improve productivity, economy.

Maintains the best machinery operating conditions operating standards, conducted on a regular basis. Contents include monitoring the operation condition, supplement or replace lubricants, periodic removal of checks. Running maintenance matters, sound, vibration, temperature, rotating one way bearing lubricant status, and so on.

2、FAG轴承的检修:轴承的清洗:拆卸下轴承检修时,首先记录轴承的外观,确认润滑剂的残存量,取样检查用的润滑剂之后,洗轴承。作为清洗剂,普通使用汽油、煤油。

拆下来的轴承的清洗,分粗清洗和细清洗,分别放在容器中,先放上金属的网垫底,使轴承不直接接触容器的脏物。粗清洗时,如果使轴承带着脏物旋转,会损伤轴承的滚动面,应该加以注意。在粗清洗油中,使用刷子清除去润滑脂、粘着物,大致干净后,转入精洗。

精洗,是将FAG轴承在清洗油中一边旋转,一边仔细的清洗。另外,清洗油也要经常保持清洁。

2, FAG bearings maintenance: cleaning of bearing: bearing under demolition when first recorded appearance of the bearing, confirming residual lubricant stock, after sampling check of lubricants, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.

Remove bearing cleaning, rough and fine cleaning, placed in a container, put the metal mesh on the bottom, bearing no direct contact with the dirt container. Coarse cleaning, if you make the bearings rotate with dirt will damage the rolling surface of the bearing, should be noted. Coarse cleaning oil, use a brush to clean grease, adhesive material, generally after clean, fine wash.

Intensive wash, is the FAG bearing the cleaning oil side rotation and careful cleaning. In addition, cleaning oils should always be kept clean.

3、FAG轴承的检修和判断:为了判断拆卸下来的轴承是否可以使用,要在FAG轴承洗干净后检查。检查滚道面、滚动面、配合面的状态、保持架的磨损情况、单向轴承游隙的增加及有无关尺寸精度下降的损伤,异常。非分离型小型球轴承,则用一只手将内圈支持水平,旋转外圈确认是否流畅。

3, FAG bearing maintenance and judgment: in order to determine whether removed bearing can be used, to get the FAG bearing clean check. Check the Raceway surface, rolling, the mating surfaces, cage wear, one-way bearing clearance increases damage of declining and has nothing to do with dimensional accuracy, the exception. Non-separable small ball bearings, inner ring support level with one hand, rotate the outer ring to confirm fluency.
