1. Wear between the output shaft and the guide copper sleeve

phenomenon:

Friction scratches appear on the output shaft

Copper chips fell from the lower end of the output shaft

There is a sharp abnormal noise between the output shaft and the guide copper sleeve

Reason: The roundness or coaxiality error of the output shaft is large, resulting in wear and tear

Solution for metal debris falling into the interior of cylinder B: Replace the worn output shaft and guide copper sleeve to ensure cleanliness inside the cylinder.

2. Damaged ball screw

phenomenon:

The output is unstable and the displacement deviation is relatively large

There is abnormal noise in the ball screw part of B

Reason:

The processing of a workpiece is not concentric, resulting in

Iron filings have fallen into the screw rod, causing damage to the screw nut. Solution: Replace the screw rod and replace the workpiece if it is not concentric

3. Bearing damage

phenomenon:

There is abnormal noise in the bearing area

The output of B is unstable and the displacement deviation is relatively large

Reason:

Iron filings have fallen into the bearing

B machining part bearing position machining part concentric

Solution: Replace the bearing. If the bearing position of the machined part is not concentric, replace the machined part

4. Synchronous belt wear

phenomenon:

There is abnormal noise in the belt section

There is a lot of black belt powder on it

Reason:

Install a synchronous belt with two ends that are not concentric

There is a problem with the matching of the synchronous belt and synchronous wheel

Solution: Replace the synchronous wheel or synchronous belt
