A drive coupling and transmitting assembly for photosensitive drum and toner cartridges is disclosed. The assembly includes a drive shaft configured in a printer to transmit a rotational driving forceand a coupling member. The coupling member includes a main drum body and a bushing member. Main drum body has a flexible shaft subassembly including a receiver, an adapter, and a flexible shaft member extended between adapter and receiver such that a first end of flexible shaft member is secured to a receiver post and a second end of flexible shaft member is secured to an upper end of adapter. The bushing member is slidably disposed between main drum body and flexible shaft subassembly. Adapter is slidably disposed in bushing member and configured with at least one rotational force transmitting pin to engage with a spiral groove disposed on bushing member such that bushing member is moved longitudinally inward or outward while rotational force transmitting pin is rotated by drive shaft ora compression and torsion spring in the spiral groove in a clockwise or counterclockwise direction. Receiver is configured to receive the rotational driving force from drive shaft and transmit the rotational driving force through flexible shaft member to adapter such that main drum body, bushing member and flexible shaft subassembly are rotated about an axis.
Description
technical field [0001] The present invention relates to the field of electrostatic image forming devices such as copiers, facsimile machines, electrophotographic printers, and replaceable or replaceable cartridges for these devices, such as toner cartridges for laser printers, and more particularly to such The rotational force from the drive mechanism used in the electrostatic image forming apparatus is mechanically coupled to another rotational apparatus. Background technique [0002] Many electrophotographic apparatuses, such as photocopiers or laser printers, use a detachable developing sleeve containing a photosensitive member. The cartridge is also referred to as a toner cartridge or developer cartridge, and it is detachably mounted to an integral copier or printer. This configuration enables the user to maintain the printing capability of the device without the assistance of a repairman. [0003] The developing sleeve is connected to a drive mechanism that rotates th...
