DRIVEN HEAD OF PHOTOSENSITIVE DRUM AND DRIVE OF IMAGING DEVICE Russian patent published in 2016 - IPC G03G15/00 

FIELD: engines.

SUBSTANCE: present invention relates to a driven head of a photosensitive drum and drive for an image forming device. Proposed driven head of an imaging device comprises a curved recess and energy transmission sections with curved inclined surfaces comprising faces to engage with the driven head of a photosensitive drum, herewith the driven head of the photosensitive drum contains a drum flange positioned on the end part of the photosensitive drum and connected with the photosensitive drum; a drum shaft running in the axial direction from the end part of the drum flange and a boss passing axially from the end surface of the drum shaft and engaged with the curved recess, herewith on the side wall of the boss there is at least one convex tooth passing in the radial direction along the boss and engaged with the power transfer section; and the convex tooth has the first side surface and the second side surface, which is an inclined chamfer gradually varying in the direction of the convex tooth root along the end part of the convex tooth.

EFFECT: technical result is ensuring high accuracy of the curved projection twisting angles and the curved recesses of a traditional driven head of a photosensitive drum in engagement between the curved projection and the curved recess.
