How to improve the wear problem of the wall vibrator

The wall vibrator is widely used. In some areas, it is also called the wall vibration exciter. It is often used in a variety of mechanical equipment to provide exciting force. The speed of use is relatively high, up to 800 revolutions per minute, and the torque carried. The impact vibration is relatively large. Because the rotation speed is relatively high, the working temperature can reach 80 °C. During long-term use, metal fatigue wear will occur.

Wear is a loss to the vibrator, which can adversely affect the exciter and shorten its service life. Can this loss be improved?

We understand that the main cause of wear is thermal stress. In order to repair the vibration and wear caused by the vibration of the exciter shaft, a more wear-resistant material is needed to repair the problems such as pits and cracks of the mechanical bearing. It is very difficult to do such a work with a single material, so I need to select more materials to complement their performance and achieve good repair and protection.
