Abstract

The invention relates to a photoreceptive drum connection assembly, which is connected to a driving shaft. The photoreceptive drum connection assembly comprises a drum gear and a connector, wherein the drum gear is provided with a first connection part, which is arranged at one end of the drum gear; a second connection part corresponding to the first connection part is arranged at one end of the connector, and the other end of the connector is provided with a connection end; a central post and a plurality of convex blocks formed by extension of the outer edge of the central post are formed at the connection end, and the convex blocks can be a plurality of spherical convex blocks; and the second connection part is detachably connected to the first connection part, and the connection end is detachably connected to the driving shaft. Therefore, the damaged drum gear or connector can be replaced, and the effects of lowering the cost, reducing castoff and lowering maintenance and repair expense are achieved further.

Description

technical field [0001] The invention mainly provides a photosensitive drum connecting assembly, especially a connecting assembly used in an image forming device for connecting a photosensitive drum and a driving shaft. Background technique [0002] Existing photosensitive drums are mainly used in image forming devices, such as figure 1 As shown, it is a photosensitive drum 1a and a drive shaft 2a currently on the market, wherein a triangular groove 21a is formed in the center of the drive shaft 2a, and the photosensitive drum 1a has a drum gear 11a and is symmetrical to the triangular groove. 21a, a triangular column-shaped bump 12a is used to facilitate the connection between the two. [0003] The existing drum gear 11a and the triangular columnar projection 12a have an integrated structure, but the wear of the drum gear 11a and the wear of the triangular columnar projection 12a are due to two different contact mechanisms, so the drum gear 11a or the triangular columnar pr...
