AI Technical Summary

Technical Problem

Existing gearbox machining equipment lacks effective positioning support during the planetary gear pressing assembly process, resulting in vibration, unstable workpiece clamping, and uneven force, which affects the positioning accuracy and overall durability of the gear ring and sun gear.

Method used

By employing a transition fit between an annular positioning groove and an annular positioning frame, combined with an elastic pressing component and an embedded slot snap-fit ​​structure, high-precision radial and axial positioning of the gear ring and sun gear is achieved, preventing offset during assembly.

Benefits of technology

Ensuring the accurate positioning of the gear ring and sun gear during assembly improves the meshing precision and overall durability of the transmission components inside the gearbox.
