Deformable Bearing Cage Rotor Thermal Contraction

The patent applies the dynamics principle by making the bearing deformable rather than rigid. The deformable bearing allows the bar to move dynamically in response to thermal contraction of the short-circuit ring during cooling, maintaining continuous contact and low electrical resistance while still providing structural support. This resolves the contradiction by replacing a static rigid connection with a dynamic adaptive connection.

The patent applies parameter changes by modifying the physical state of the bearing material to be deformable. The bearing's material properties are selected to allow controlled deformation under thermal stress, enabling the bar to follow the contraction of the short-circuit ring. This changes the parameter of bearing rigidity to an optimal intermediate state that provides both support and adaptability.

The deformable bearing provides a dynamic support system that adapts its rigidity based on operational conditions. During normal operation, it provides sufficient mechanical support to maintain bar positioning, while during thermal contraction, it deforms to allow bar movement. This dynamic behavior resolves the contradiction between free movement and mechanical support.

The bearing acts as an intermediary element between the rigid slot and the bar. It mediates the interaction by providing controlled deformation, allowing the bar to move when necessary while maintaining mechanical support. The bearing absorbs the thermal stress and transfers it to the slot in a controlled manner, protecting both the bar and slot from damage.

The patent simplifies the bearing structure by focusing on material property changes rather than complex mechanical designs. The deformable bearing achieves its function through careful selection of material properties (viscoelastic or plastic deformation characteristics) rather than through complex geometries or multiple components. This reduces device complexity while maintaining the required functionality.

The bearing is designed as a flexible element that can be made from thin-walled structures or flexible materials. This approach simplifies the overall structure compared to rigid mechanical assemblies with multiple moving parts. The flexible nature of the bearing allows it to deform smoothly under thermal stress without requiring complex mechanisms.
