AI Technical Summary

Technical Problem

Existing lightweight alloy threaded connection technologies suffer from problems such as difficulty in achieving high-strength connections, complex processing, high costs, and poor maintainability.

Method used

The double-ended stud connection structure includes a double-ended stud, a bearing cap, a positioning sleeve, and a hexagonal head positioning nut. Precise positioning is achieved through interference fit and clearance fit. The preload generated by the rotation of the stud ensures uniform distribution of thread stress.

Benefits of technology

It achieves high-strength threaded connections with a load capacity of 10.9 or higher, and features good maintainability and easy disassembly and assembly, thus reducing manufacturing costs.
