Driving force receiving assembly of photosensitive drum

Abstract

The invention discloses a driving force receiving assembly of a photosensitive drum. The driving force receiving assembly of the photosensitive drum is used for receiving rotating force of a driving head of an image forming device and transmitting the rotating force to the photosensitive drum through a photosensitive drum gear arranged at the end part of the photosensitive drum to drive the photosensitive drum to rotate. The driving force receiving assembly comprises a driving force receiving part, a driving force transmission part and a gear matching part, wherein the driving force receiving part is engaged with an engaging part of the driving head of the image forming device; the driving force transmission part is connected with the driving force receiving part and the gear matching part; the gear matching part is matched with the photosensitive drum gear; and the driving force receiving assembly is engaged with the driving head in a manner of forming a fixed angle by a vertical intersection line of the center point of the engaging part and the rotating center line of the driving head and the vertical intersection line of a stress point of the driving force receiving part and the rotating center line of the driving force transmission part. By the driving force receiving assembly, driving force transmission can be stably and reliably achieved; and the condition that a process cartridge is smoothly put in/taken out can be ensured.

Description

technical field [0001] The present invention relates to a process cartridge having a photosensitive drum used in a laser printer, copier or facsimile machine, and more particularly, to a driving force receiving assembly used on the photosensitive drum in the process cartridge. Background technique [0002] Electrophotographic image forming apparatuses such as laser printers, copiers, facsimile machines, etc. usually have a process cartridge inside, and the process cartridge can be detached from the electrophotographic image forming apparatus. Existing process cartridges mainly include the following categories: an integrated box in which the photosensitive drum and the developing device, charging device and cleaning device are arranged together, and an integrated box in which the photosensitive drum and the charging device are arranged together, or the photosensitive drum and the developing device are arranged together split box. Whether it is an integrated process cartridge...

Problems solved by technology

[0004] The method of using the swing rod to assist the telescopic method or the main machine door cover to assist the push of the swing rod depends on the structure of the machine, the compatibility is not good, and there is a problem that the machine is not in place or it is difficult to take it out; There are problems such as slippage caused by the failure of the drive parts to mesh with the drive head of the main engine when turning in at certain angles when landing

Moreover, no matter it is a process box that adopts a pendulum-assisted telescopic mode or a main machine door cover that assists in pushing the pendulum, or a process box that is created and dismantled by force, the drive head must be in contact with the drive during the process of loading / unloading the process box. The drive claws of the force receiving component are in contact. If the position is not appropriate, there will be problems such as the drive claw of the drive force receiving component meshing with the drive head of the main engine, etc.
