Hey!!! This is me Violet Z here! Keep the cool stuff coming!
Please Make detailed video on Inner Ring split ball Bearing
I was asked about this knowledge in the job interview, I am so glad that I watched this video!!
That's fantastic to hear! I'm thrilled that the video was helpful for your job interview. If there are any other topics or questions you'd like assistance with, feel free to let me know. Thank you for sharing your success story!
As usual, very useful!
As usual, very appreciated!
Thanks 🙏
You’re welcome 😊

Thank you for the love! ❤️
Thanks for the video and for sharing your knowledge. Could you suggest some books about the topics of rotor dynamics?
Thank you so much
I will appreciate it if you can provide videos on below topics
1- sub synchronous vibration
2- misalignment effect on rotor dynamic
3- thermal management of bearings
4- Optimum damping and stiffness determination of flexible rotor
5- SFD design process for flexible rotors
6- Operation of SFD (oil pressure, temperature correlation for required damping value)
7- Open ended and close ended SFD design criteria and which approach is suggested for better operation
Thanks in advance
But what about thermal expansion in the housing? The housing is die cast aluminum and the bearing and shaft are steel... So they have different coefficients... And the higher temperature will make loose fit even more loose...
Your question suggests that you may be relatively new to designing rotating equipment. It's important to note that temperature stabilizes over time rather than increasing indefinitely. This allows for an optimal fit between the bearing, shaft, and housing. In most cases, the bearing acts as the primary heat source, while the housing functions as a heat sink. As a result, the thermal expansion will typically be greater on the bearing side compared to the housing.

"Thank you for the suggestion! I'll definitely consider making a video on vibrations in the future. If you have any specific aspects of vibrations you'd like me to cover in the video, please let me know. Your input is valuable for creating content that meets your interests.
