What is the harm if the shaft is worn out

The main parts between products must be applied to the rotating shaft. The shaft that bears both bending moment and torque during rotation is called the rotating shaft. And if it is worn, what kind of harm will it bring?

In fact, wear is the most common problem in the use of the shaft, which is mainly caused by the metal characteristics of the shaft: although the metal has high hardness, it has poor resistance (that is, it cannot be restored after deformation), poor fatigue resistance, and poor impact resistance. Therefore, it is easy to cause abrasive wear, adhesive wear, fatigue wear, fretting wear, etc. Most of the shaft wear is not easy to detect. Only when the machine has high temperature, large beating amplitude, abnormal noise, etc., will it be noticed. However, when people find out, most of the shafts have been worn, resulting in machine downtime.
