Abstract
The utility model discloses a Se-drum core gear wheel, comprising a gear wheel body; one end of the gear wheel body is provided with a gear wheel working surface, and the other end thereof is concentrically matched with the inner wall of the drum core; and the outer wall of one end of the gear wheel body concentrically matched with the inner wall of the drum core is provided with a plurality of glue sinking grooves. Since the outer wall of one end of the Se-drum core gear wheel body concentrically matched with the inner wall of the OPC drum core is provided with a plurality of glue sinking grooves, proper friction force is reasonably used and the mount of glue is increased so that the gluing is firm; moreover, the glue cannot be overflowed, thereby preventing the outer surface of the gear wheel from being polluted.
Description
Technical field
The utility model relates to the parts of a kind of printer or duplicating machine, relates in particular to a kind of toner cartridge drum core gear.
Background technology
Toner cartridge on existing printer or the duplicating machine generally comprises parts such as bulging core, magnetic roller, powder delivery cutter, waste powder hopper and powder box, wherein rouses core and is made up of aluminium base pipe 2 that has applied the OPC material and the bulging core gears 1 that are assemblied in aluminium base 2 pipes, one end.
As shown in Figure 1, existing bulging core gear 1 is provided with some card keys 13 with the outer circumference surface of the end that aluminium base 2 pipes are connected, the inwall of corresponding aluminium base pipe 2 is provided with and blocks the draw-in groove 21 that key 13 matches, and drum core gear 1 is connected by draw-in groove 21 and card key 13 with aluminium base pipe 2.Card key 13 on the above-mentioned bulging core gear 1 is easy to wear after long-term work, and drum core gear 1 and aluminium base pipe 2 cause the matching loose between them because the variation of environment temperature can be expanded with heat and contract with cold, and influences the printing effect of printing.
Summary of the invention
The invention provides a kind of toner cartridge drum core gear, solved the problem that glue is bonding and glue is excessive of OPC drum aluminium base pipe of core and gear mass.
A kind of toner cartridge drum core gear comprises the gear body, and gear body one end is provided with the working gear face, and the other end has some glue deep gouges with drum in-core wall concentric fit, gear body with an end outer wall of drum in-core wall concentric fit.
The quantity of described glue deep gouge is 8～12.
Described band glue deep gouge position uniform ring is listed on the gear body outer wall, is filled in the groove position with anti-spilled outside influence drum core outward appearance so that glue is evenly distributed and surplus glue can be taken advantage of a situation, and is bonding more firm.
The outside wall surface of the utility model toner cartridge drum core gear is offered the glue deep gouge, has increased the loading of glue, makes bondingly firmly and can not allow glue excessive, avoids polluting the gear outside surface.
Description of drawings
Fig. 1 is existing drum core gear and the aluminium base pipe of the bulging core of the OPC structural representation when unassembled;
Fig. 2 is for having the structural representation after the aluminium base pipe of drum core gear and OPC drum core assembles now;
Fig. 3 is the utility model drum core gear and the aluminium base pipe of the bulging core of the OPC structural representation when unassembled;
Fig. 4 is the utility model drum core gear and the aluminium base pipe of the OPC drum core structural representation after assembling.
Embodiment
As shown in Figure 3 and Figure 4, a kind of toner cartridge drum core gear comprises gear body 1, and an end of gear body 1 is provided with working gear face 11, and the other end is cylindrical and become the concentric circles plus tolerance to cooperate with aluminium base pipe 2 inner chambers of OPC drum core.Have 10 glue deep gouges 12 on the outer circumference surface of this end.Certainly the shape of gear body 1 this end can change with aluminium base pipe 2 inner chamber specifications size and alteration of form, and the quantity of glue deep gouge 12 also can be adjusted, and operated by rotary motion is at 8～12.For bonding more firm, glue deep gouge 12 general uniform ring are listed on gear body 1 outer wall.
When assembling, an end and the aluminium base pipe 2 of OPC drum core that gear body 1 is provided with glue deep gouge 12 add suitable pressure by specific installation, the gear lasso end that scribbles suitable glue is pressed into OPC drum in-core with one heart, utilize normal friction to add the bonding force of glue, make gear become concentric circles to be closely linked with OPC drum core, glue spots can prevent that in glue deep gouge 12 inside it is excessive, assembling process does not need the clamping copolymerization, and is easy for installation.
