Mechanical Design Manual Bearing Fit Tolerance Issues Help
Thread Content
This post was last edited by Youqing on 2020-6-16 14:03. The attached picture shows the rolling bearing tolerance and fit chapter of the Mechanical Design Manual (Chengdu University version). The fit table of the bearing and the shell is divided into upper and lower parts. From the above, it can be understood that the bearing outer diameter tolerance can be found according to the basic dimensions of the bearing outer diameter and the hole diameter tolerance that matches the bearing outer diameter. The problem is that the lower half of the table is based on the basic dimensions. How to check the gap interference? I am confused. Please give advice.
You will know by drawing the two tolerance zones and overlapping them, and take the limit size
You explained it clearly and I feel so stupid. This is a table. I looked at it as two parts. When the basic dimensions are consistent, the tolerance value and gap interference of the corresponding tolerance zone are determined. Thank you very much.
You're welcome. If you have any questions, come to Haichuan and ask.
