Seeking advice on sealing issues for high-speed rotating shafts (direct motor drive)
Thread Content
I have a question regarding the sealing of high-speed rotating shafts (directly driven by motors): Oil is present at one end, and due to poor sealing, this oil leaks into the motor (the motor operates at 5000 rpm), causing motor failure. What are some good suggestions for sealing solutions? It would be helpful if specific details could be provided, such as the type of seal, materials used, and design aspects Thank you so much!
It’s best to view the video; as for the sealing method, we can only discuss it by looking at the video, for reference purposes.
Try using a shaft seal with a spiral sealing line
5000 revolutions per minute – contact sealing is not suitable; consider a labyrinth design along with an oil return groove
