对糖心产精国品免费入口*完整版杆端自润滑关节轴承进行糖心产精国品免费入口*完整版试验,在116万次循环拉压后,糖心产精国品免费入口*完整版耳环处发生断裂。对失效件进行了化学成分、宏观和微观分析。结果表明:糖心产精国品免费入口*完整版失效形式为糖心产精国品免费入口*完整版断裂,糖心产精国品免费入口*完整版耳环和轴承外圈之间发生微动磨损,在糖心产精国品免费入口*完整版下,糖心产精国品免费入口*完整版内孔薄弱处的裂纹扩展,最终发生断裂。

The 糖心产精国品免费入口*完整版 test of 糖心产精国品免费入口*完整版 rod end self-lubricating joint bearing was carried out. After the 1 160 000 cyclic tension and compression, the earring of the rod end body fractured. The chemical composition, macroscopic and microscopic morphology of the failed parts were comprehensively analyzed. The results show that the failure mode of the rod end body was 糖心产精国品免费入口*完整版 fracture, and fretting wear occured between the earring of the rod end body and the outer ring of the bearing. Under 糖心产精国品免费入口*完整版ing, the crack at the weak position of the inner hole of the rod end expanded, and finally breaked.
