Embodiment Construction

[0040] The structure of the drive assembly in a process cartridge is as follows:

[0041] Figure 6 It is an exploded schematic view of the drive assembly in the process box used in the embodiment. As known from the figure, the drive assembly in the process box includes: a flange 20 that is arranged at the end of the rotating part and transmits power to the rotating part; The power transmission mechanism for the driving force of the image forming device, the elastic element 40 that acts as a buffer, and the connecting piece 7 that connects the flange 20 with the power transmission mechanism.

[0042] Figure 7 and Figure 8 They are the three-dimensional schematic diagram and the cross-sectional view of the flange respectively. As can be seen from the figure, the flange 20 includes: a cylindrical groove 20d coaxial with the flange, a central shaft hole 20c set on the axis of the flange, and a central axis hole 20c set in the groove 20d A pair of radially symmetrically distr...

Abstract

The invention relates to a driving assembly in a processing box anda processing box with the driving assembly; the driving assembly comprises a flange, a power transmission mechanism located in the flange, and an elastic element disposed between the flange and the power transmission mechanism for resetting; the flange comprises a pair of flange force-bearing parts which are symmetrically distributed radially; the power transmission mechanism comprises a power transmission member, a support column, an elastic element force-bearing part, a power receiving part, a pair of force transmission parts which are symmetrically distributed radially, and a support disc; the power transmission member is sleeved by the support disc. The power transmission member is supported by the support disc and the support column, so sloshing of the power transmission member generated during rotation relative to the flange is reduced.

Description

technical field [0001] The invention relates to a drive assembly in a process box and a process box including the drive assembly. Background technique [0002] A process cartridge is a cartridge that can be detachably loaded into the main body of an image forming apparatus, and includes a photosensitive drum, a charging unit, at least a rotating roller (such as a developing roller, a toner feeding roller) and cleaning elements as an integral unit. One of the processors, etc., the photosensitive drum and the turning roller are both rotatable parts in the process cartridge. Since the processing box is detachably installed relative to the main body of the device, it is convenient for maintenance of the device. The electrophotographic image forming device using the electrophotographic imaging method works like this: the light of the image forming device selectively exposes the photosensitive drum that has been uniformly charged by the charging unit to form an electrostatic late...
