Analysis of spalling parts
发布时间:2021-07-29浏览次数:5

Test results: the axial runout of inner ring and outer ring obviously exceed the standard, indicating that the internal accuracy has deteriorated;

The dimensional accuracy of 7 steel balls in the bearing was tested. The measured diameter group difference of the steel ball was 0.8u m, slightly exceeding the standard requirements. Among them, the dimensional deviation of the steel ball in the cracked pocket of the cage was slightly larger, as shown in Table 2.

Analysis of spalling parts

The spalling part of the inner raceway was observed under the scanning electron microscope, and no material defects such as inclusions were found. There were metal convex edges at the spalling source, which were distributed in an arc and gradually extended to the spalling center. As shown in Fig. 8, the spalling property is fatigue spalling.
