Socket Joint Spring Finger Geometry for Controlled Preload

The patent extracts the preload control function from separate components (like Belleville washers) and integrates it directly into the bearing structure itself. The bearing races are designed with specific geometric features that inherently provide preload control, eliminating the need for additional preload components and reducing overall device complexity while maintaining reliable preload control within the confined space.

The patent merges the preload control function with the bearing structure by integrating geometric features directly into the bearing races. This combination allows the bearing to simultaneously support loads and provide controlled preload, reducing the number of separate components needed and simplifying the overall assembly while fitting within the confined operable space.

The patent applies local quality by designing specific geometric features at particular locations on the bearing races. The race geometry includes localized features such as curved surfaces or specific profile shapes that create a progressive spring rate effect, providing controlled preload while limiting load changes during travel through the localized geometric design rather than requiring a uniformly high spring rate throughout.

The patent utilizes parameter changes by designing the bearing race geometry to create a variable spring rate effect. The geometric features are configured to provide different stiffness characteristics at different points in the travel range, effectively changing the spring rate parameter to maintain controlled preload while minimizing excessive load changes over the full range of motion.

The patent segments the bearing structure into distinct functional zones with specific geometric features on the inner and outer races. These segmented features include localized curved surfaces, profile variations, or geometric discontinuities that create controlled interaction points, enabling the bearing to simultaneously provide support functions and generate controllable preload through the segmented geometric design.

The patent introduces geometric features on the bearing races as intermediary elements that mediate between the ball elements and the housing. These intermediary geometric features on the race surfaces create the desired preload control by providing controlled contact and interaction points, enabling preload generation without requiring separate ratchet or locking mechanisms.
