Abstract: Power receiving unit and process cartridge are provided. The power receiving unit of a process cartridge is detachably mounted in an image formation apparatus configured with a power output unit that is swingable. An outer circumference of the power output unit contains a recessed portion, and the power receiving unit is engaged with the power output unit to receive a driving force. The power receiving unit includes a protrusion. The protrusion is disposed inside the power receiving unit. The protrusion is engaged with the recessed portion of the power output unit to receive the driving force. When the power receiving unit moves along an axial direction thereof and is in a contact engagement with the power output unit, the protrusion abuts against a front end of the power output unit to cause the power output unit to be tilted and swung.

Abstract: Power receiving unit, rotating component, process cartridge, and assembly and disassembly methods thereof are provided. The process cartridge is detachably mounted in an image formation apparatus configured with a swingable power output unit, an outer circumference of the power output unit contains a recessed portion, and the power receiving unit is engaged with the power output unit to receive a driving force. The power receiving unit comprises a wheel hub, a power receiving part, and a bias part. The wheel hub is disposed on an end of a rotating component in the process cartridge. The power receiving part includes a fixing protrusion and a notch that are oppositely disposed, the fixing protrusion is inserted into the recessed portion, and the notch provides a swinging space for the power output unit. The bias part provides a bias force toward the fixing protrusion for the power output unit.
