Directional Locking Nut with Rolling Members

The locking mechanism uses movable rolling members that can dynamically transition between different positions within recesses. These rolling members automatically adjust their position based on the direction of applied force, providing dynamic locking in one direction while allowing movement in the opposite direction, thus resolving the contradiction between reliability and structural simplicity

The locking nut is segmented into multiple functional components: the threaded portion for engagement, multiple recesses distributed around the circumference, and rolling members within each recess. This segmentation allows each component to perform its specific function independently, providing reliable locking through distributed rolling members while maintaining manufacturing simplicity through modular design

The rolling members automatically perform the locking function without requiring external control systems or complex actuation mechanisms. When a loosening force is applied, the rolling members naturally roll into positions that block the loosening direction, providing self-service locking that enhances reliability while avoiding additional complexity from control systems

The rolling members act as intermediary elements between the threaded connection and the locking function. These intermediaries translate applied forces into locking actions, providing a simple mechanical solution that prevents loosening without requiring complex electronic or hydraulic locking systems
