“…8 (a) shows that the worn surface has lots of furrows. The threebody abrasive wear is the major form of wear during the service time [11][12][13][14][15][16] . Under the continuous action, the furrows gradually grow wider and deeper along with the removal of the base materials.…”

The severely worn position and failure mechanisms of the ring die of a feed pellet machine were investigated. The macroscopic and microscopic morphologies of the failed surface, the chemical composition and mechanical properties of the collected samples were analyzed using scanning electron microscopy, energy disperse spectroscopy, optical emission spectrometry, and a universal testing machine. Results show that the dip angle at the entrance of the ring die hole between the roller and ring die was severely worn. The feed powder could not be fully extruded through the dip angle at the entrance of the ring die holes, thus the density of the feed particles produced could not meet the requirements. Therefore, abrasive wear under high stress is the main reason of failure at the entrance of the ring die holes under the action of feeding powder; and cutting and fatigue spalling lead to substantial material loss. In addition, a high damp-heat environment aggravates abrasive wear on the die hole internal surface.

“…Generally, the bearing failure was attributed to the interacted failure factors of bearing, including human factors, equipment factors, material, processing methods and qualities, and service condition. 6 A large number of failure analysis cases in the previous references confirmed that the bearing life was obviously influenced by the material quality (large inclusions, defects), heat treatment quality, 7,8 stress concentration, 9 unreasonable design, 10 improper process, 11 environmental factors, [12][13][14] machined surface quality [15][16][17][18] , and overload. [19][20][21] To the best of our knowledge, there is no systematic and effective failure analysis method for the water pump shaft bearing.…”

The shaft bearing is the key component of water pump and its fatigue failure results in the abnormal operation of the system. However, the failure mechanisms of bearing are still unclear. In this paper, the failure analysis on the engine water pump shaft bearing was carried out by using the measurement of material composition and properties, observation of macro and micro morphologies, and theoretical analysis of fatigue failure. The wear behavior and failure mechanisms were clarified, and the prevention measures was further proposed. The bearing failure reflected from the fracture of bearing cage and serious wear of roller and mandrel. The wear behavior of the mandrel originated from the surface fatigue, and the failure was attributed to the large radial deflection load. Further, the decreased weight of impeller and shaft connector and the increased bearing thickness were recommended to improve the bearing operation.
