Need help: What’s going on here? Rotork electric valve actuator
Thread Content
The shaft end of the gearbox was pushed out. What is the reason? How to fix it? Thank you!
Have it repaired. It is caused by internal jamming. It is caused by a faulty limit switch or an overload fault.
Take it apart and analyze it; address each specific issue individually
I’m also very curious; please let me know if there are any results.
Upon disassembly, it was found that the rolling bearing at the drive end of the drive shaft was damaged. It is likely a lubrication failure.
Can’t we turn to the manufacturer or its agent in such a situation?
The actuator has low torque; it’s a fundamental deficiency.
I contacted the manufacturer, who replied that the actuator and gearbox might not be compatible.
Guru! Why does bearing damage to the drive shaft occur when the torque is low?
If the torque is low, everything in the reducer becomes smaller; it’s impossible to prevent it from breaking.
