How to Mend Bean Peeling Machine Bearing If It Is Damaged

Bean peeling machine bearing is an important part which should be changed in time if it is damaged.

Weld preheating shaft and the end cap inner hole is preheated to 150-250℃. We usually adopt J507Fe welding rod for the bearing. And we use the ordinary welding rod for the end cap inner hole. After welding, we should bury it into the lime powder for slow cooling and control the cold shortness phenomenon caused by shock cooling. When we mend the BEAN PEELING MACHINE BEARING by electrowelding, we should pay attention to the following points:

When the motor shaft neck is less then 40mm, we can adopt the method of 6-8 equally divided parts line-shape surfacing. When the motor shaft neck is more than 40mm, we can adopt full surfacing method. This is decided by the transmission force of the bean peeling machine bearing output power. No matter which method, we should notice to adopt continuous electrode manipulation and symmetric welding to avoid too large change of the bean peeling machine bearing concentricity.

When the concentricity adjusted value is not more than 0.015mm, we should avoid too large noise from high-speed rotation and heat generated from vibration, which can reduce the service life span of the motor.
