Description
[technical field]
The present invention relates generally to a kind of printer with photosensitive drums shaft end gear in the toner cartridge and power transmission part thereof.
[background technology]
Toner cartridge is a kind of important consumable components in image forming apparatus such as duplicating machine, printer and the facsimile recorder; The removable image processing system that is loaded on is convenient to terminal user's maintenance, in general; Toner cartridge is made up of development part that realizes developing and the imaging moiety that forms electrostatic latent image; Photosensitive drums is positioned at imaging moiety, accepts the driving force from image forming apparatus, realizes rotatablely moving; The transmission of this power or realize, or the logical rotation that realizes photosensitive drums by the Transmission Part of photosensitive drums through gear drive.
In the course of work; Toner cartridge is along putting into image processing system perpendicular to photosensitive drums axis direction; For smooth installation and the installation back Transmission Part of realizing toner cartridge links to each other with the accurate of drive end of image processing system; Be provided with universal joint between the rotating shaft of existing toner cartridge Transmission Part and the photosensitive drums turning axle, utilize the ball-type of universal joint to connect, Transmission Part can move in certain degree of freedom.
Let Transmission Part and image processing system drive end accurately work good; Also need respective track be set at image processing system; Guarantee that in the installation process, Transmission Part is elevated and slips into assigned address along track, complex structure; And, cause processing request and cost all higher owing to adopted gimbal structure.
[summary of the invention]
In order to address the above problem, the present invention provides a kind of photosensitive drums shaft end gear and Transmission Part.
Described photosensitive drums shaft end gear is cylindric, and an end directly embeds in the photosensitive drums axle sleeve admittedly; Other end inner hollow; And offer two ball recess, shaft end gear is accepted the rotary power from Transmission Part, drives photosensitive drums with this; In the course of work, shaft end gear is in order to the miscellaneous part gear run-in synchronism of driving with its engagement simultaneously.
Described Transmission Part mainly comprises ball support, conveyor screw two parts, through the cylinder pivot pin the two is contacted.
Described conveyor screw, an end is cylindric, and pin hole is offered in the side; The spirochetal other end is the screwed union of band concave ball shape; Toner cartridge is along in the vertical direction installation process of photosensitive drums axis, and when Transmission Part during against the printer driver end, spirochetal concave spherical joint is admitted a protrusion spheroid of printer driver end; Concave ball shape screwed union on the conveyor screw is fixed, and acceptance that can be stable is from the power output of printer driver end.
Described ball support adopts rigid high-abrasive material; Comprise disk and the ball post two parts that have ball, the disc centre perforate, pore size and conveyor screw cylindrical end are complementary; The pin hole with conveyor screw cylindrical end consistent size is offered in the disk side; With disk and conveyor screw series connection, prevent that the two from relatively rotating by the cylinder pivot pin, effectively stop the ball support to endwisely slip simultaneously along the conveyor screw cylindrical end; The two ends of said disk are two ball posts that have ball, and the ball post is symmetrically distributed, and designs for integral type with disk.Force in output along photosensitive drums axis direction; Can make the ball on the ball post easily snap in two ball recess establishing in the photosensitive drums shaft end gear; Ball has level of freedom in ball recess; And along photosensitive drums axis direction certain sliding space is arranged, the reverse application of force can be separated the ball recess of ball support with the photosensitive drums shaft end gear, when the printer driver output when the photosensitive drums axis rotates; Support ball on the output applies tangential force for simultaneously photosensitive drums shaft end gear inner spherical groove, rotates around axis thereby drive the photosensitive drums main body.
The present invention is simple in structure; Make that again the transmission of coaxial rotation is more reliable between Transmission Part and photosensitive drums; Because the ball holder part of Transmission Part adopts the integral type design, does not use gimbal structure, so processing request and cost are not high yet; And Transmission Part detachably is installed in photosensitive drums one end in ground, be convenient to safeguard photosensitive drums like this.

[embodiment]
According to accompanying drawing and embodiment the present invention is done further elaboration below.
As shown in Figure 1; Transmission Part (3) one ends are connected with photosensitive drums (1) shaft end gear (2); The screwed union of the other end (7) is admitted a protrusion spheroid of printer driver end, and the concave ball shape screwed union (7) on the conveyor screw is fixed, and acceptance that can be stable is from the power output of printer driver end.
As shown in Figure 2; The disk (6) of ball support is enclosed within spirochetal cylindrical end (5); Rotating circular disk (6); Make pin hole and the pin hole centering on the conveyor screw cylindrical end (5) on the disk (6), insert cylinder pivot pin (9), guarantee that disk (6) and spirochetal cylindrical end (5) can not relatively rotate and slide.
As shown in Figure 3; Two ball recess (8) are offered in photosensitive drums shaft end gear (2) inside; Force in output along photosensitive drums (1) axis direction, can make the ball on the ball post (4) easily snap in two ball recess (8) of establishing in the photosensitive drums shaft end gear (2), ball has level of freedom in ball recess (8); And certain sliding space being arranged along photosensitive drums axis direction, the reverse application of force can make ball separate with the ball recess (8) of photosensitive drums shaft end gear (2).
Toner cartridge is along being installed in the process of printer perpendicular to photosensitive drums (1) axis direction; Screwed union on the Transmission Part (7) at first contacts a protrusion spheroid of printer driver end; Make the concave ball shape screwed union (7) on the conveyor screw held fixing; Under the installation thrust, the ball on the Transmission Part ball post (4) is along the past photosensitive drums main direction rollback of the inner ball recess (8) of photosensitive drums (1) shaft end gear (2), thus the smooth installation of realization toner cartridge; Transmission Part is beneficial to the smooth rollback of Transmission Part just being provided with rounded feature in the contact position with the printer driver end.After toner cartridge was installed smoothly, the screwed union on the Transmission Part (3) was stably accepted the driving of printer driver power, and driving force is transferred to the shaft end gear (2) on the photosensitive drums (1) by two support balls (4), drives photosensitive drums (1) rotary work with this.
