The main part between the product and the product must be applied to the rotating shaft. The shaft used for rotating work to bear both bending moment and torque is called the rotating shaft. And if it was worn, what harm would it do?

Wear is actually one of the most common problems in shaft use, mainly caused by axial metal characteristics: metal while high hardness, poor but concessions (that is, deformation is unable to recover after), poor fatigue resistance, impact resistant performance is poor, so easy to cause abrasive wear, adhesive wear and fatigue wear and fretting wear, etc. Most of the shaft wear is not easy to detect, and will only be detected when the machine is high temperature, large jumping range, abnormal noise, etc., but when people notice, most of the shaft has been worn, thus causing the machine to stop.
