  • Arrangement for securing at least one circlip against centrifugal force, which circlip is axially fastened on a rotor shaft of an electrical machine for positional securing, and use of an arrangement of this type
    Patent number: 11939998
    Abstract: An arrangement secures at least one circlip against centrifugal force. The circlip is axially fastened on a rotor shaft of an electrical machine for positional securing. At least one securing element is provided for securing against the centrifugal forces acting on the circlip when the rotor shaft rotates. The at least one securing element is placed onto the rotor shaft by means of a first portion for fastening and, by means of a second portion, is slid at least partially over the circlip and radially secures the circlip.

  • Assembly for securing the axial position of a sun gear of a planetary gearing stage on a rotor shaft of an electrical machine, and use of such an assembly
    Patent number: 11287028
    Abstract: An assembly secures the axial position of a sun gear of a planetary gearing stage on a rotor shaft of an electrical machine. The sun gear has an end section that is stepped radially outward on the inner diameter and is axially secured on the rotor shaft by means of at least one securing ring. At least one securing element is provided to secure against the centrifugal forces acting on the securing ring during rotation of the rotor shaft. The securing element is inserted into the end section on the sun gear and is at least partially pushed over the securing ring and radially secures the same.
