How should the design and manufacturing of moving parts be considered?

This post was last edited by Haitian LSHW on 2011-4-20 08:12. I used to work with static equipment; now I’m dealing with some dynamic equipment, and there may be quite a few changes needed in terms of design and manufacturing. I’d like to discuss this with everyone. What are the requirements for welds on parts that experience vibration, such as whether crack formation needs to be taken into account? What are the requirements for bolt connections on moving parts, and how is bolt loosening generally addressed? Thank you.

Reply to 1# Haitian LSHW: I don’t understand what you mean by “institution”. I haven’t heard of the names “moving mechanism” and “static mechanism” either. I’ve never heard that \"mechanisms for motion\" have high precision while \"mechanisms at rest\" have low precision. I hope the original poster will take another look at books to find out what an institution is Such as four-bar link mechanisms, jaw crushers (four-bar link mechanisms), and train wheel drives (four-bar link mechanisms) – where do they have high precision and where do they have low precision?

Leave one open loop in the dimension chain (an increase loop or a decrease loop). It is a loop of cumulative processing and assembly errors. “\"The moving parts use hinge seats while the stationary parts are connected with bolts\" – I don’t understand what you mean The coupling is a moving component – why is it connected using bolts? Go and read \"Mechanics Principles\" by yourself; the questions you’re asking are ridiculous
