Embodiment Construction

[0040] figure 1 Shown is a photosensitive drum 10 to which a driving assembly 1 according to an embodiment of the present invention is applied. The driving assembly 1 is fixed at one end of the drum main body 9 of the photosensitive drum 10. The peripheral surface of the drum main body 9 has a photosensitive layer. The driving assembly 1 is used to receive the rotational driving force from the printer driving mechanism, and transmit the rotational driving force to the drum main body 9, so that the drum main body 9 rotates around its axis under the action of the rotational driving force.

[0041] Figure 2 ~ Figure 4 The basic composition of the driving assembly 1 is shown, and its structure mainly includes a gear 2 , a rotating driving force receiving head 3 , an adjusting slider 4 , an adjusting rod 5 , a rotation limiting pin 6 , a limiting bottom plate 7 and a helical compression spring 8 . The gear 2 is closely matched with one end of the drum main body 9, the axis of the...

Abstract

The invention provides a photosensitive drum driving assembly which comprises a gear wheel and an adjusting assembly, wherein the gear wheel is closely fitted at one end of a photosensitive drum; the adjusting assembly comprises a rotary driving force receiving head which extends out of the gear wheel; the adjusting assembly can be arranged in the gear wheel to move in reciprocating translation relative to the gear wheel along the axial direction of the photosensitive drum and a first direction vertical to the axial direction, and an elastic support part and an axial limit part are arranged between the adjusting assembly and the gear wheel; and the rotation driving force receiving head can be rotatably arranged on the adjusting assembly around the axis per se. Compared with the prior art, the photosensitive drum driving assembly allows simple and convenient assembly, and has stable structure performance; and a processing box in which the photosensitive driving assembly is adopted ensures stable disembarking and stable operation and has reliable performance.

Description

technical field [0001] The present invention relates to a photosensitive drum driving assembly for a process cartridge. Background technique [0002] In an image forming apparatus such as an electrostatic copier, a digital copier, or an all-in-one printer, a developing device for developing an electrostatic latent image formed on a photosensitive drum is provided, and the developing device deposits toner on the electrostatic latent image for development. Usually, the toner powder consumed by developing is generally provided by the process cartridge, and when the toner powder in the process cartridge is used up, a new process cartridge will be replaced. [0003] Generally, the process cartridge operates by receiving the driving force of the image forming apparatus through a photosensitive drum driving assembly assembled at one end of the photosensitive drum. US Patent Application Publication No. US2008 / 0152388A1 discloses a process cartridge, in which the photosensitive drum...
