Problems solved by technology

In the prior art, in order to prevent the power receiving member 0212 whose third part is spherical from protruding from the flange cylinder 0210, as image 3 As shown, a barb 02107 is provided on the protruding part 02105 close to the opening of the flange cylinder, and along the radial direction of the flange cylinder, the distance between the opposite barbs is smaller than the third part The diameter of 0212c, however, if the distance is too small, although it can effectively prevent the power receiving part from falling off, it will cause the third part 0212c of the power receiving part to not be easily pressed into the flange cavity; if the distance is too large , it will not be able to effectively prevent the power receiving part from falling off, therefore, the distance must be precisely controlled, that is, the size of the barb part 02107

Embodiment 1

[0052] like Figure 7 As shown, the power transmission device 21 includes an interconnected force applying mechanism 211 and a power receiving mechanism. Preferably, the power receiving mechanism is located at one longitudinal end of the photosensitive cylinder 22 , and the force applying mechanism 211 is located inside the photosensitive cylinder 22 . In this embodiment, the power receiving mechanism includes a power receiving member 212 for receiving driving force from the outside. In order to accommodate the power receiving member 212 more stably, the power receiving mechanism also includes a movable part 217 for carrying the power receiving member 212 , the force applying mechanism 211 is combined with the movable part 217; in order to transmit the driving force to the photosensitive cylinder 22 stably, the power transmission device 21 also includes a flange cylinder 210 installed on a longitudinal end of the photosensitive cylinder 22, and the movable part 217 is combined...

Embodiment 2

[0069] In the above embodiment, the thread in the power receiving mechanism is directly set in the matching groove 2175 of the movable part 217. During mass production, the movable part 217 is generally formed by injection molding of non-metallic material. However, the matching groove 2175 rotates relative to the screw rod 2112 for a long time Slipping may occur in the process, therefore, in order to ensure the overall stability of the power transmission device 21, the power transmission device in this embodiment also includes a movable part 214 made of metal, and this embodiment is the same as the above-mentioned embodiment Parts will have the same number.

[0070] like Figure 7 As shown, the movable part 214 is actually a nut, and the movable part 217 also includes a second receiving part 2174 arranged on the base part 2170. The second receiving part 2174 has a side opening 2178, or in other words, the second receiving part 2174 is formed to extend inwardly from the outer ...

Abstract

The invention relates to a processing cartridge which comprises a processing cartridge shell and a light-sensitive part which is rotationally mounted in the shell. The light-sensitive part comprises a light-sensitive cylinder and a power transmission device connected with the light-sensitive cylinder; the device comprises a force application mechanism and a power receiving mechanism connected with each other; the power receiving mechanism comprises a power receiving piece used for receiving driving force from the exterior; the power receiving piece comprises a first part, a second part and a third part; the second part is used for connecting the first part and the third part; the first part is positioned at one tail end of the second part and comprises a supporting part and at least one pair of power receiving parts extending towards a direction far away from the direction of the second part from the top surface of the supporting part along a rotating axis L3 of the power receiving piece; two entrances are formed between the two power receiving parts; the entrances are always in the same direction as an assembling / disassembling direction of the processing cartridge. Therefore, the power receiving piece is not interfered, and the processing cartridge can be smoothly assembled or disassembled.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a process box detachably installed in an electrophotographic imaging device. Background technique [0002] Electrophotographic imaging is the process of using the photosensitivity of the photosensitive member to charge and expose the photosensitive member, and then sequentially develop, transfer, fix and clean; the process box is a consumable in the process of electrophotographic imaging, including multiple The rotating member, in addition to the above-mentioned cylindrical photosensitive member, also includes components for charging it, such as a cylindrical charging roller, and developing components, such as a cylindrical developing roller or magnetic roller, in electrophotography Both are constantly rotating during the imaging process, therefore, during the electrophotographic imaging process, rotational power must be provided to the rotating member. [0003] If the...
