Abstract
The invention discloses a clearance compensation straight gear, which comprises a driving gear and a driven gear, wherein the driving gear is connected with the driven gear together; one side that the driving gear is combined with the driven gear is provided with a cavity; the cavity is internally provided with a spring; the central parts of the driving gear and the driven gear are provided with connecting holes; parts close to edges are provided with positioning holes; two ends of the spring are respectively embedded into the positioning holes of the driving gear and the driven gear; and the driving gear is provided with two thread positioning holes. The clearance compensation straight gear provided by the invention has the advantages that the structure is simple, the distance of needles of a sewing machine can be reasonably controlled, reset of the needles of the sewing machine can be guaranteed, and processing is not influenced, so that the sewing quality is improved.
Description
Technical field
The present invention relates to the sewing machine field, relate in particular to a kind of gap compensation spur gear.
Background technique
Sewing machine owing to phenomenons such as broken string and card cloth can occur, needs to squeegee again circuit after occurring pausing when making in course of working.Existing compensation device rotates by the handwheel that is arranged on sewing machine edge mostly, realizes the compensation of needlework by the belt drivening rod; But the easy position of crossing of this device compensation method influences quality of processing.
Summary of the invention
Technical problem to be solved by this invention is, a kind of gap compensation spur gear of can reasonable compensation making circuit is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of gap compensation spur gear, comprise driving gear and driven gear, described driving gear and driven gear link together, the one side that driven gear combines with driving gear is provided with cavity, be provided with spring in the described cavity, driving gear and driven gear center portion are provided with attachment hole, the edge position of keeping to the side is provided with positioning hole, and the two ends of spring is embedded in respectively in the positioning hole of driving gear and driven gear.
Preferably, described driving gear is provided with the screw thread positioning hole.
Preferably, described screw thread positioning hole has two.
Compared with prior art, usefulness of the present invention is: this gap compensation spur gear is simple in structure, can rationally control the eedle needle gage, and can guarantee that eedle resets, and does not influence processing, has improved sewing quality.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of gap compensation of the present invention spur gear structural representation.
Among the figure: 1, driving gear; 2, driven gear; 3, spring; 4, attachment hole; 5, positioning hole;
6, screw thread spacing hole; 7, cavity.
Embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of gap compensation spur gear shown in Figure 1, comprise driving gear 1 and driven gear 2, described driving gear 1 links together with driven gear 2, the one side that driven gear 2 combines with driving gear 1 is provided with cavity 7, be provided with spring 3 in the described cavity 7, driving gear 1 and driven gear 2 center portions are provided with attachment hole 4, and the edge position of keeping to the side is provided with positioning hole 5, and the two ends of spring 3 is embedded in respectively in the positioning hole 5 of driving gear 1 and driven gear 2; In order to fixedly connected with drive link and to be easy for installation and removal, described driving gear 1 is provided with two screw thread positioning holes 6.
This gap compensation spur gear is simple in structure, can rationally control the eedle needle gage, and can guarantee that eedle resets, and does not influence processing, has improved sewing quality.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
