轴承钢采用连铸机锻造时，二次散热区域分布在扇形截面上，故又称扇形截面轴承。这种轴承经常用于钢厂和其余工业，如果经常发生故障，整个南京INA轴承钢加工系统可能会瘫痪。因此，为了降低扇形轴承的维护成本，提高整个生产线的加工效率，有必要对失效原因进行分析。
When bearing steel is forged by continuous casting machine, the secondary heat dissipation area is distributed on the sector section, so it is also called sector section bearing. Such bearings are often used in steel mills and other industries, and if frequent failures occur, the entire Nanjing INA bearing steel processing system may be paralyzed. Therefore, in order to reduce the maintenance cost of sector bearing and improve the processing efficiency of the whole production line, it is necessary to analyze the failure reas***.
（一）负荷分布的不均匀性
(1) the inhomogeneity of load distribution
（1）装南京INA轴承配不当造成的载荷分布不均匀。主要原因是前轴承、轴和滚子的匹配没有获得准确的测量。解决这一问题的更好的方法是调整零件之间的配合指。
(1) uneven load distribution caused by improper bearing of INA bearing in Nanjing. The main reason is that the matching of front bearing, shaft and roller has not been accurately measured. A better way to solve this problem is to adjust the mating fingers between parts.
（2）径向间隙不均匀引起的负荷不均匀。当轴承安装在同一滚子上时，如果间隙值过大，就会产生不均匀的轴承力，从而对南京INA轴承造成损坏。解决办法是适当调整轴承安装在同一滚子上的间隙。
(2) uneven load caused by uneven radial gap. When the bearing is installed on the same roller, if the clearance value is too large, it will produce uneven bearing force, thus causing damage to Nanjing INA bearing. The solution is to properly adjust the clearance between bearings mounted on the same roller.
（二）污染物***
(two) pollutant intrusion
外来污染物的***主要有两个原因。首先，轴承本身是密封的，使轴承容易受到杂质的直接***，或者由于杂质在密封装置周围积聚，杂质容易进入轴承内部扇形轴承，南京INA轴承停止，I.T固定。由于轴承清洗工作没有到位或在维护环境和工作工具上都不干净，使污染物进入轴承，导致轴承寿命缩短。
There are two main reas*** for the invasion of foreign pollutants. First of all, the bearing itself is sealed, so that the bearing is vulnerable to direct invasion of impurities, or because impurities accumulated around the sealing device, impurities easy to enter the bearing internal sector bearing, Nanjing INA bearing stopped, I.T fixed. Because the bearing cleaning work is not in place or in the maintenance of the environment and working tools are not clean, so that pollutants into the bearing, resulting in shortened bearing life.
为了解决这个问题，我们需要做的就是改进轴承密封装置，它不仅可以防止漏油，而且可以防止污染物的***。同时，风机轴承须清洗和***。
To solve this problem, we need to do is to improve the bearing sealing device, it can not only prevent oil leakage, but also prevent the invasion of pollutants. Meanwhile, fan bearings must be cleaned and maintained.
（三）径向间隙尺寸的影响。
(three) the influence of radial clearance size.
间隙的大小不仅影响南京INA轴承的载荷分布不均匀，而且会引起轴承噪声、温升、旋转精度下降等故障。因此，有必要合理选择扇形轴承的径向游隙。
The size of clearance not only affects the uneven load distribution of Nanjing INA bearings, but also causes bearing noise, temperature rise, rotation accuracy decline and other faults. Therefore, it is necessary to choose the radial clearance of sector bearings reasonably.
