MUD MOTOR ROTOR WITH CORE AND SHELL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240026880 titled 'MUD MOTOR ROTOR WITH CORE AND SHELL

Simplified Explanation

The abstract of the patent application describes a rotor for a mud motor. The rotor includes a core with a first outer shape and a shell positioned around the core with a second outer shape that is different from the first outer shape. The second outer shape of the shell defines lobes and cavities that engage a stator bore during rotation of the rotor relative to the stator. The thickness of the shell varies around the core, ranging from a non-zero minimum thickness to a maximum thickness.

  • The rotor for a mud motor has a core and a shell.
  • The core has a first outer shape, while the shell has a second outer shape that is different from the first outer shape.
  • The second outer shape of the shell includes lobes and cavities.
  • The lobes and cavities engage a stator bore during rotation of the rotor.
  • The thickness of the shell varies around the core, ranging from a non-zero minimum thickness to a maximum thickness.

Potential Applications:

  • Mud motors used in drilling operations
  • Oil and gas exploration and extraction
  • Mining operations
  • Geothermal drilling

Problems Solved:

  • Improved engagement between the rotor and stator
  • Enhanced efficiency and performance of mud motors
  • Reduced wear and tear on the rotor and stator components
  • Increased durability and lifespan of mud motors

Benefits:

  • Increased drilling efficiency and productivity
  • Reduced downtime and maintenance costs
  • Improved control and stability during drilling operations
  • Extended lifespan of mud motor components


Original Abstract Submitted

a rotor for a mud motor includes a core having a first outer shape, and a shell positioned around the core, the shell having a second outer shape that is different from the first outer shape, the second outer shape defining one or more lobes and one or more cavities that are configured to engage a bore of a stator during rotation of the rotor relative to the stator. a thickness of the shell varies as proceeding around the core, from a non-zero minimum thickness to a maximum thickness.
