扬州INA轴承高温疲劳失效分析 来源:御狮轴承   点击:次   日期:2018-07-26 11:57

扬州INA轴承失效分析是工作面可靠性工程的重要组成部分。轴承是轴承的重要组成部分(轴承功能导致故障或不工作,在规定的损耗下)(轴承故障可分为其正常寿命故障和两次故障)。早期失效主要是由于点蚀和疲劳引起的早期失效,并提出了建议。为了提高轴承的使用寿命和可靠性,提出了改进措施。

Failure analysis of INA bearing in Yangzhou is an important part of reliability engineering of working face. Bearing is an important part of the bearing (the bearing function causes failure or non work, under the prescribed loss) (the bearing fault can be divided into its normal life failure and two failures). Early failure is mainly due to early failure caused by pitting and fatigue, and suggestions are put forward. In order to improve the service life and reliability of bearings, improvement measures are put forward.

扬州INA轴承的疲劳失效是一种失效表面形式,主要表现为疲劳裂纹的萌生、扩展和断裂,其中长期失效载荷的金属是交替产生的。

The fatigue failure of the INA bearing in Yangzhou is a failure surface form, which is mainly manifested by the initiation, expansion and fracture of fatigue cracks, in which the metal of long term failure load is produced alternately.

扬州INA轴承由玻璃纤维增强尼龙66制成。适用于不超过120度的温度。当油在润滑油中使用时,如果油中含有添加剂,可以缩短保持架的使用寿命。当扬州INA轴承温度超过120度时,老化油也会缩短保持架的使用寿命。因此,应注意定期观察和更换润滑油。

Yangzhou INA bearing is made of glass fiber reinforced nylon 66。 It is suitable for a temperature of no more than 120 degrees。 When the oil is used in lubricating oil, if the oil contains additives, the service life of the cage can be shortened。 When the INA bearing temperature in Yangzhou exceeds 120 degrees, the aging oil will also shorten the service life of the cage。 Therefore, attention should be paid to regular observation and replacement of lubricating oil。

密封的扬州INA轴承用经过特殊测试的锂基润滑脂润滑。这种润滑脂能在短时间内经受120度的高温。如果稳定工作温度达到70℃或更高,则缩短了标准锂基润滑脂的使用寿命。

Sealed Yangzhou INA bearings are lubricated with specially tested lithium grease. This grease can withstand 120 degrees of high temperature in a short time. If the stable working temperature reaches 70 centigrade or higher, the service life of the standard lithium base grease is shortened.

高温工作时必须使用特殊的润滑脂。还必须使用耐热材料作为密封装置。标准接触密封不应超过110度的使用温度。

Special grease must be used when working at high temperature。 It is also necessary to use heat-resistant material as a sealing device。 Standard contact seals should not exceed 110 degrees of service temperature。

如果使用扬州INA轴承高温合成材料来密封它,还必须考虑非常有效的氟化材料,其释放有害的健康气体和烟雾超过300度。我们应该更加注意使用火炬来去除圆锥滚子轴承。

If the Yangzhou INA bearing high temperature synthetic material is used to seal it, it is also necessary to consider very effective fluorinated materials that release harmful health gases and smog over 300 degrees。 We should pay more attention to the use of torch to remove tapered roller bearings。

1,圆锥滚子扬州INA轴承比相同体积的滑动轴承小得多,因此滚动轴承具有更大的径向尺寸。因此,轴颈轴承经常被用作内燃机曲轴轴承,重载、小直径和严格的结构要求。

1, the tapered roller Yangzhou INA bearing is much smaller than the same volume sliding bearing, so the rolling bearing has greater radial dimension. Therefore, journal bearings are often used as crankshaft bearings for internal combustion engines, with heavy load, small diameter and strict structural requirements.

2,扬州INA轴承的振动和噪声较大,特别是在后期。因此,对高精度轴承的要求非常高,不允许振动。一般来说,滑动轴承的效果更好。

2, the vibration and noise of INA bearing in Yangzhou are large, especially in the later stage. Therefore, the requirements for high-precision bearings are very high and vibration is not allowed. Generally speaking, the effect of the sliding bearing is better.

3,圆锥滚子轴承对金属废料和其他异物特别敏感。一旦与异物混合,就会产生间歇性的振动和噪声,很容易导致损坏。因此,滚动轴承的使用寿命有一定的局限性。简而言之,类似于INA的轴承寿命比滑动轴承短。

3, tapered roller bearings are particularly sensitive to metal scrap and other foreign objects. Once mixed with foreign matter, it will produce intermittent vibration and noise, which can easily lead to damage. Therefore, the service life of rolling bearings has certain limitations. In short, the life of bearings similar to INA is shorter than that of plain bearings.
