The invention proposes a photosensitive drum driving assembly, which includes an outer casing, a transmission shaft sleeve installed on the inner upper part of the outer casing, an output shaft installed on the inner lower part of the outer casing, a gasket installed between the transmission shaft sleeve and the output shaft, and a The cover plate on the upper part of the shaft sleeve, the first straight bevel gear installed in the cover plate, the input shaft installed on the top of the first straight bevel gear, the second straight bevel gear installed on the inner side of the transmission sleeve and matched with the first straight bevel gear Tooth bevel gear, the third straight bevel gear that is installed on the output shaft top and cooperates with the second straight bevel gear. The photosensitive drum driving assembly of the present invention has a simple structure, and realizes the balance of axial force through the cooperation of three sets of straight-toothed bevel gears, so as to ensure that the photosensitive drum driving assembly stably transmits the driving force from the image forming device and drives the process box reliably. Work.
Description
technical field [0001] The invention relates to a driving assembly, in particular to a photosensitive drum driving assembly. Background technique [0002] A process cartridge is a seed cartridge detachably mounted in an image forming apparatus, and the process cartridge includes an electrophotographic photosensitive assembly and at least one of processing devices such as a charging assembly, a developing assembly, and a cleaning assembly as an integral unit. The image forming device using electrophotographic imaging works like this: after the charging assembly in the process box charges the photosensitive drum with a uniform charge, the light scanning element in the image forming device selectively illuminates a part of the photosensitive drum, A layer of electrostatic latent image is formed on the surface of the photosensitive component, and the developing component uses toner to develop the electrostatic latent image into a toner image, and the toner image is transferred t...
