DRUM ASSEMBLY, CARTRIDGE, ELECTROPHOTOGRAPHIC IMAGING DEVICE AND COUPLING Russian patent published in 2022 - IPC G03G21/16 

FIELD: information technology.

SUBSTANCE: invention relates to information technologies, namely to means of image formation. A drum assembly comprising a photosensitive drum and a coupling functionally connected to the photosensitive drum, wherein the coupling includes the main part, a protrusion capable of moving relative to the main part, the first elongated section supporting the protrusion, the second elongated section connected to the first elongated section, and a connecting section between the first elongated section and the second elongated section, while the first elongated section is connected to the main part through the second elongated section, with the first direction, in which the first elongated section extends from the connecting section, and the second direction in which the second elongated section extends to the connecting section are opposite to each other relative to the axial direction of the coupling.

EFFECT: increasing the wear resistance of the main node of the imaging device.
