Problems solved by technology

However, in this assembly method, on the one hand, during the installation process, the drive assembly is axially squeezed by the image forming device so that the drive assembly moves along the axis L of the photosensitive drum. This extrusion requires a large external force and is not convenient for installation. , Disassembly; on the other hand, the drive assembly must move along the axis L of the photosensitive drum, making the connection between the drive assembly and the photosensitive drum more complicated

Embodiment 1

[0044] like figure 1 As shown, the driving assembly 100 of the present invention includes a power receiving part 101, a power transmitting part 102 and a power driving part 103; it is used to receive the rotational force of the driving head of the main body of the image forming apparatus, and pass the rotational force through the rotating force provided at the end of the photosensitive drum. The photosensitive drum hub is transmitted to the photosensitive drum to drive the photosensitive drum to rotate. When the drive assembly receives and transmits the rotational force of the drive head of the host, the drive assembly has a rotation axis, and the rotation axis coincides with the axis of the photosensitive drum, and at this time, the power transmission part is not bent away from the axis of the photosensitive drum deformed state. When the process cartridge including the photosensitive drum is mounted in and removed from the main body of the image forming apparatus, the power ...

Embodiment 2

[0053] like Figure 5 and Image 6 As shown, this embodiment differs from Embodiment 1 in that: the drive assembly further includes a limit member 104 arranged along the drive assembly, and the limit member 104 has the following characteristics: Bending deformation will not occur when the force in the direction of the drum axis) is applied, and bending deformation may occur deviating from the axis of the photosensitive drum when subjected to forces in other directions; the limiting member 104 is a steel strip-shaped sheet, or a polyethylene sheet or a Thin tube; one end of the limiting member 104 is connected with the power receiving part 101 , and the other end is connected with the photosensitive drum hub 200 . In this embodiment, a horizontally protruding post 101d is provided on the receiving portion base 101b, a positioning hole 200b is provided in the photosensitive drum hub 200, one end of the limiting member 104 is connected to the post 101d, and the other end is fixe...

Embodiment 3

[0057] This embodiment is a photosensitive drum provided with the driving assembly as described in Embodiment 1 or Embodiment 2, the photosensitive drum hub is provided at the end of the photosensitive drum, and the top of the photosensitive drum hub has a through hole for the driving assembly to pass through. The transmission part passes through the through hole and is exposed outside the through hole, and the power driving part is located in the through hole.

Abstract

The invention relates to a driving assembly and a photosensitive drum and a process cartridge including the same. The driving assembly is used for receiving the rotational force of the driving head of the main body of the image forming apparatus, and transmitting the rotational force to the photosensitive drum through the photosensitive drum hub arranged at the end of the photosensitive drum. The photosensitive drum is used to drive the photosensitive drum to rotate, including: a power receiving part, which is engaged with the main drive head of the image forming device and receives power from the main drive head of the image forming device; the power driving part is connected with the photosensitive drum and drives the photosensitive drum to rotate; the power The transmission part connects the power receiving part and the power driving part, and transmits the power from the driving receiving part to the power driving part; the power transmission part can be bent and deformed away from the axis of the photosensitive drum. In the drive assembly of the present invention, the power transmission part can be bent relative to the axis of the photosensitive drum when it is stressed. During the installation and removal of the process cartridge, due to the bending deformation of the power transmission part due to the force, the installation and removal space can be obtained, which is convenient for installation. , dismantling.

Description

technical field [0001] The present invention relates to a process cartridge with a photosensitive drum used in laser printers, copiers or facsimile machines, and more particularly, to a drive assembly used on the photosensitive drum in the process cartridge, and a process cartridge using the drive assembly. Background technique [0002] The process cartridge is a cartridge that is detachably installed in the main body of the image forming apparatus. The process cartridge as an integral unit includes a photosensitive drum, a charging unit, a rotating roller (such as a toner feed roller, a developing roller) and a cleaning element, etc., the photosensitive drum and the The rotating rollers are all rotatable parts in the process cartridge. Since the process cartridge is detachably mounted with respect to the main body of the image forming apparatus, maintenance of the image forming apparatus is facilitated. An electrophotographic image forming apparatus employing the electroph...
