The developing assembly of the carbon powder box is used for supplying development for an imaging system, and a device which is used for supplying the development in the developing assembly is generally named as a photosensitive drum. The structure of the photosensitive drum is formed by a drum cylinder and a gear driving assembly, wherein the gear driving assembly of the photosensitive drum is connected with a driving slot of a printer when in work so that a rotating power device is provided for the carbon powder box, and the structure of the gear driving assembly is formed by a driving assembly fixing shaft and a driving shaft. According to the gear driving assembly of the photosensitive drum, disclosed by the invention, the structure is simple, the performance is reliable, and the work is stable.
Description
Technical field
It is that a kind of laser printer uses the photosensitive drum gear drive end assembly in the cartridge developing apparatus that type of the present invention relates to.。
Background technology
It is the developing device of cartridge that a kind of laser printer uses that type of the present invention relates to, and this cartridge developing device is that imaging system provides development, and this developing apparatus that provides is photosensitive drums usually.The structure of photosensitive drums is by conducting end, drum barrel, gear drive end assembly; This gear drive assembly divides driven unit stationary shaft, driving shaft two parts to constitute; Wherein driving shaft one end is the spherosome shape; And can be movable at driven unit axle fixed part; The stationary shaft internal activity space of spherosome body and gear drive assembly through the axle of overdriving when cartridge is put into printer mobile makes driving shaft fully contact with the driver slot of printer; When printer in when work, the drive shaft turns of the moving photosensitive drums of the rotating band of printer driver groove, thereby the revolving force that provides for cartridge.
The shortcoming of the drive assembly of photosensitive drum of said structure be the driving shaft in the driven unit be prone to come off (particularly coming off in the process of transportation) with when the work contact with the driven unit fixed part can forfeiture driving function hidden danger; Job insecurity when power is provided; Openly examine the structure that the photosensitive drums assembly of asking adopts spring at Chinese patent CN 101916055A; This structure is the adjustment assembly; It includes the rotary driving force that stretches out outside the said gear and receives head; The adjustment assembly can along photosensitive drum shaft to and perpendicular to this axial first direction is arranged at respect to gear in the middle of this gear with reciprocating and flatly moving, be provided with elastic support member and axial limiting parts between adjustment assembly and the gear; Rotary driving force receives head and can be arranged at rotatably on the said adjustment assembly around self axis, and this complex structure causes the photosensitive drum gear driven unit of developing device to come off or causes and gear drive assembly stationary shaft loose contact forfeiture drives function.。
Summary of the invention
The object of the invention does not contact the photosensitive drum gear driven unit difficult drop-off of the developing device in this cartridge and cartridge with gear drive assembly stationary shaft when the work can lose the driving function; Stable rotation power can be provided, simple in structure, the convenience of this driven unit.
For realizing above-mentioned purpose, the present invention provides following technical scheme: a kind of gear drive assembly of photosensitive drums is provided, and this driven unit comprises driven unit axle stationary shaft, driving shaft bipartition.
Driving shaft is made up of drive end, spherosome, driving shaft stiff end three parts; Drive end is made up of two branch protrusion engaging nails; Constitute with coupling shaft between drive end and the spherosome, constitute by coupling shaft between driving shaft stiff end and the spherosome, thereby form an integral body.
The driven unit stationary shaft is made up of gear set, driven unit spherosome activity space and photosensitive drums inwall connecting portion; Gear set is distributed in the driven unit outside; Gear set, driven unit spherosome activity space, photosensitive drums inwall connecting portion constitute an integral body.
Driving shaft and driven unit stationary shaft are combined into an integral body.The spherosome of driving shaft is positioned at driven unit stiff end internal activity space, and the spherosome fixing pin is fixed on spherosome in the pickup groove of drive assembly of photosensitive drum stationary shaft spherosome activity space upper strata through the fixed orifice in the middle of the spherosome; The driving shaft stiff end extends to spherosome activity space lower part through the spherosome activity space to the other end; Wherein the driving shaft stiff end has a fixed orifice, and the driving shaft fixing pin is fixed on the driving shaft stiff end in the pickup groove of drive assembly of photosensitive drum spherosome activity space lower part through this fixed orifice.
Driven unit spherosome activity space is positioned at drive assembly of photosensitive drum inside, and the spherosome activity space is divided into two-layer up and down, up and down each pickup groove.The upper strata pickup groove is a fixed drive axle spherosome fixing pin, its objective is that the cartridge rotary power that the printer driver groove provides when work drives the drive end of drive assembly of photosensitive drum, thereby drives the photosensitive drums rotation; Another purpose of upper strata pickup groove is to prevent that the inner lower floor of driving axial photosensitive drums from moving or come off.Lower floor's pickup groove is a fixed drive axle drive fixing end fixing pin, its objective is to prevent the driving axial external moving or come off; Photosensitive drums inwall connecting portion its objective is that in the individual outside lower end of photosensitive drums drive group drive assembly of photosensitive drum becomes as a whole with the fixed connection of photosensitive drums.
The driving shaft that the present invention has the drive assembly of photosensitive drum of said structure can not come off, and can stable rotation power be provided for photosensitive drums.
