Rod end joint and assembling method thereof

A rod end joint and its assembly method, and the manufacturing technical field in the field of mechanical design, including a custom Rod End Fittings pipe body, a threaded bushing, a threaded joint, the threaded bushing is connected to one end of the pipe body, the threaded joint is connected to the threaded bushing, and the threaded bushing is Cylindrical,One or both ends have grooves distributed along the circumferential direction. The middle of the cylindrical surface has an annular groove along the circumferential direction. The inner hole is a threaded hole.


The part of the pipe body corresponding to the groove of the threaded bushing is fixed with the threaded bushing through the indentation process. , The part of the pipe body corresponding to the annular groove of the threaded bushing is fixed with the threaded bushing through the rolling groove process.

The threaded joint and the threaded bushing are connected by threads. The threaded pipe body and the threaded bushing groove and the indentation and rolling of the annular groove realize the butt joint of the dissimilar material pipe body and the threaded joint without reducing the connection strength.

The rod obtained by the end joint and its assembly method is simple in structure, light in weight, and low in manufacturing cost, and is especially suitable for the dual requirements of general aircraft to reduce the manufacturing cost and weight of mechanical components.
