AI Technical Summary

Technical Problem

The assembly process of flexible bearings in harmonic reducers is complex, and misalignment can easily lead to bearing damage and scrapping, resulting in a high scrap rate and low assembly efficiency.

Method used

A flexible bearing assembly fixture for a harmonic reducer is adopted, including a base plate fixed on the worktable, a fixture positioning shaft and a chuck. The chuck slides with the base plate and is equipped with an elastic guide component. The thrust is provided by a compression spring to achieve precise positioning and dynamic adjustment of the flexible bearing.

Benefits of technology

This improved the accuracy and success rate of flexible bearing assembly, reduced the risk of scrap, and ensured concentricity and assembly efficiency.
