軸承是所有機械設備中最常使用的關鍵零組件之一，而大部分軸承在長時間的操作下後都需要定期的保養及維修，以減少可能因為軸承磨損所產生的影響，但工業界對於軸承缺陷的成因及後續維修保養的方法都不甚了解，甚至保養及維修的作法都有許多改善的地方。
本研究主要針對自調心球面滾子軸承元件進行破損探討及分析。當軸承於不同運轉條件下，其運轉間隙將因彈性變形而有所變化，進而影響到軸承的性能，導致軸承的使用壽命縮短，使得在工業界應用上有所限制。本研究將採用標準軸承安裝的方式，利用千分錶準確設定安裝間隙，並使用本實驗室所設計的軸承性能測試設備，進行量測及記錄軸承運轉性能的數據，隨時監控軸承性能及狀態的變化，同時記錄軸承內外環滾道及球面滾子所產生的磨損情況，進而分析其破損的型態分析及表面微結構的改變，做為工業界增加自調心滾子軸承的使用壽命與保養維修的參考。

Bearings are one of the most commonly used key components in all mechanical equipments. Most bearings require regular maintenance and repair after long-term operation to reduce the possible impact of bearing wear. The causes of bearing defects and subsequent maintenance methods are not well-known by industries, even maintenance and repair practices have many improvements. This study will discusses and analyzes the damage of self-aligning spherical roller bearing components. When the bearing is under different operating conditions, its operating clearance will change due to elastic deformation, which will affect the performance of the bearing, shorten the life span of the bearing, and limit its application in the industrial world. This study will adopt the standard bearing mounting method, use a dial indicator to accurately set the installation clearance, and use the bearing performance testing equipment, which designed by our laboratory, to measure and record the data of the bearing while operating, and monitor the bearing performance and status at any time. Futhermore, the wear conditions of the inner and outer ring raceways and spherical rollers of the bearing are recorded, and then the morphological analysis of the damage and the change of the surface microstructure are analyzed, so as to increase the service life and maintenance of the self-aligning roller bearing in the industry.
