Water pump bearing crack analysis

How is the water pump bearing crack? For water pump bearing fatigue crack cause fracture, extend the steps and the stripe is clear, deepens, along with the crack extension speed constantly decreases, and the final stand-off stay for a period of time, traces of staying on the fracture surface. Water pump bearing fracture can be divided into three areas, fatigue crack propagation region, transient crack and the crack source area. When the water pump bearing crack extension to the critical value, shaft combined stress of the remainder of the section there's no way to overcome bending and twisting, which is mainly composed of shear stress can cause instantaneous shear fatigue damage.
