Abstract
The utility model provides a correction tape driving wheel with simple structure and easy fabrication. The driving wheel comprises a columnar hub, a gear arranged at the shaft side of the hub, a plurality of independent arced plates arranged in the circumferential direction to form the side of the hub far from the gear and protrusion blocks arranged at the outer side of each arced plate in the axial direction. The outer diameter of the hub is set smaller than the inner diameter of a tape-delivering wheel, and the protrusion blocks are arranged at the outer side of individual arced plates in the axial direction, so that the friction in inner diameter between each protrusion block and the tape-delivering wheel provides a frictional force required for a correction tape. The driving wheel has simple structure, easy fabrication and no complicated process control.
Description
Technical field
The utility model relates to a kind of correction band, relates in particular to a kind of correction band driving wheel.
Background technology
Revise band be used for revising write or the mistake of print procedure for known, it generally comprises housing, is located at driving wheel, driven pulley, take-up pulley, feed roller and band mouth in the housing, described feed roller is located on the driving wheel, described take-up pulley is located on the driven pulley, described driving wheel and driven pulley engaged transmission and be configured to the linear velocity of driving wheel and the linear velocity of driven pulley consistent.But because the footpath of the correction roll coil of strip on the feed roller constantly reduces, and the correction tape base material coil diameter on the take-up pulley constantly increases, like this in the process of driving wheel and driven pulley engaged transmission, feed roller will be arranged to slide relatively to compensate the length difference that driving wheel and driven pulley engaged transmission cause with respect to driving wheel, guarantees to revise the band operate as normal.With reference to figure 1, present it gear 2 that comprises four flexure strips 1 of circumferential setting and be located at axial sides of driving wheel that uses, described four flexure strips 1 can be with respect to the feed roller strain of its radial outside, when revising tape base material overtension, feed roller can be slided along circumferential with respect to four flexure strips 1 of driving wheel like this.This kind driving wheel is when producing, and the craft precision of four flexure strips 1 requires very high, even the difference of daytime and night, summer and winter, assembling occasion and use occasion all can be brought adverse influence to the normal use of revising band.
Summary of the invention
The purpose of this utility model provides a kind of correction band driving wheel simple in structure, easy to make.
The technical solution of the utility model is such: a kind of correction band driving wheel, comprise the column wheel hub and be located at the gear of hub spindle side, described wheel hub is made up of the some arcs that along the circumferential direction are separated away from that side of gear, and described each arc radial outside is provided with projection.
Above-mentioned correction band driving wheel, described arc has four.
The beneficial effects of the utility model are to abandon the flexure strip structure of known driving wheel complexity, but the wheel hub external diameter is arranged to less than the feed roller internal diameter, at each arc radial outside projection is set then, the friction by each projection and feed roller internal diameter provides the frictional force of revising in the band use.This driving wheel is simple in structure, and is convenient for production.
Description of drawings
Fig. 1 is known driving wheel stereogram;
Fig. 2 is the embodiment stereogram;
The specific embodiment
With reference to figure 2, embodiment discloses a kind of correction band driving wheel, it comprises column wheel hub 3 and is located at the gear 4 of wheel hub 3 axial sides, described wheel hub 3 is made up of four arcs 31 that along the circumferential direction are separated away from that side of gear 4, and the radial outside of described each arc footpath plate 31 is respectively equipped with projection 311.When feed roller was sheathed on this driving wheel, four projections 311 in the driving wheel outside can satisfy with the sliding friction of feed roller internal diameter revised band use needs, and the driving wheel of this kind structure is simple in structure, convenient for production like this.
In the foregoing description, described each arc can be to be fixedly arranged on gear shaft on the sidewall of a side with the form that is separated from each other respectively, and it belongs to another embodiment of the present utility model.The quantity of described arc is not limited to four, also can be three or five etc., can realize the purpose of this utility model equally.
Claims (2)
1. revise the band driving wheel for one kind, comprise the column wheel hub and be located at the gear of hub spindle side, it is characterized in that: described wheel hub is made up of the some arcs that along the circumferential direction are separated away from that side of gear, and described each arc radial outside is provided with projection.
2. correction band driving wheel according to claim 1 is characterized in that: described arc has four.
