Fluid Pump Rotor Axial Fixation via Deformable Locking Element

The connection between the rotor and axle is segmented into modular components: a retaining ring with radial arms that can be independently installed and removed, allowing the rotor assembly to be separated from the axle without damaging either component. This enables easy repair and replacement while maintaining stable operation during use.

The retaining ring is designed with flexible radial arms that can dynamically adapt to assembly tolerances and thermal expansion during operation, ensuring stable connection. During repair, these arms can be easily disengaged to allow rotor removal, providing dynamic adaptability between operational stability and repairability.

The thermal joining process is replaced with a mechanical retention system using a retaining ring with radial arms that engage with grooves on the axle and rotor. This mechanical connection provides sufficient holding strength without requiring heat input, eliminating welding spatter and thermal distortion while simplifying manufacturing.

The connection method changes from thermal (welding) to mechanical (retaining ring), fundamentally altering the joining parameters. The retaining ring uses elastic deformation of its radial arms to create a strong mechanical interlock without thermal energy input, reducing manufacturing complexity and avoiding heat-related defects.

The rotor assembly is segmented from the axle through the removable retaining ring, allowing the rotor to be easily replaced with different models or specifications to adapt to varying operating conditions such as different flow rates, pressures, or fluid types, while maintaining reliable connection during each specific application.

The retaining ring design serves multiple functions: providing reliable mechanical retention during operation, enabling easy removal for adaptation, and accommodating different rotor types through standardized groove dimensions. This universal retention mechanism supports both reliability and adaptability across various operating conditions.

The thermal joining process is completely replaced with a mechanical retention system using a retaining ring that uses elastic deformation and geometric interlocking to achieve strong connection. This eliminates heat input that causes thermal distortion and welding spatter, while also eliminating the acoustic noise associated with thermal processing equipment.

The retaining ring is designed as a simple, inexpensive mechanical component that can be easily replaced if needed, eliminating the need for complex thermal joining equipment. This disposable-like simplicity reduces both heat input and acoustic noise by removing thermal processing from the manufacturing process entirely.
