Self-Generating Device with Integrated Cooling for Mechanical Systems

The self-generating device merges the rotor assembly and stator assembly into a single integrated unit that converts mechanical energy from the main shaft directly into electrical energy. This combination allows the mechanical system to simultaneously perform its primary mechanical function while generating electricity, resolving the contradiction by integrating energy generation within the existing mechanical structure rather than adding separate systems.

The main shaft serves dual functions: transmitting mechanical power to the operating part and simultaneously driving the rotor assembly to generate electricity. This multi-functionality reduces the need for separate dedicated generators, thereby improving electricity generation capability while minimizing the increase in overall device complexity.

The bearing is segmented into two distinct races (first race and second race) with different functional requirements. The first race supports radial loads from the inner balls, while the second race supports both radial and axial loads from the outer balls. This segmentation allows each race to be optimized for its specific load type, improving overall bearing reliability while reducing the cumulative manufacturing precision requirements compared to a single complex race structure.

The bearing design extracts and separates the load-bearing functions into distinct components: the first race handles primary radial loads, while the second race handles secondary radial and axial loads. By taking out and addressing each load type separately with specialized race structures, the design achieves high reliability without requiring excessive manufacturing precision across a single monolithic structure.
