Problems solved by technology

[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 projection 12a often occurs When one of the stud bumps 12a is damaged and both have to be replaced together

Abstract

The invention discloses a photosensitive drum connection component which is connected with a driving shaft. The photosensitive drum connection component comprises a drum gear and a connector, wherein the drum gear is provided with a first connecting part; the first connecting part is arranged at one end of the drum gear; the first connecting part is provided with a column; a second connecting part which corresponds to the first connecting part is arranged at one end of the connector; the second connecting part is provided with a groove; the column corresponds to the groove; a connecting end is formed in the other end of the connector; a middle column and a plurality of convex blocks which are formed by extending from the outer edge of the middle column are arranged at the connecting end; the second connecting part is separably connected with the first connecting part; the connecting end is separably connected with the driving shaft. Therefore, damaged drum gears or connectors can be replaced, so that the effects of lowering the cost, reducing waste and saving the repairing expense are achieved.

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...
