Abstract
The utility model relates to a backlash compensation spur gear which comprises a driving gear and a driven gear. The driving gear and the driven gear are connected together. A cavity is formed in the surface where the driving gear is combined with the driven gear. A spring is arranged in the cavity. The center portion of the driving gear and the center portion of the driven gear are respectively provided with a connecting hole. A positioning hole is formed in the position, close to the edge, of the driving gear. A positioning hole is formed in the position, close to the edge, of the driven gear. The two tips of the spring are embedded in the positioning hole of the driving gear and the positioning hole of the driven gear respectively. The driving gear is provided with two thread positioning holes. The backlash compensation spur gear has the advantages of being simple in structure, capable of reasonably controlling the needle pitch of a frame needle, capable of ensuring the effect that the frame needle returns, and free of influence on machining, and improving sewing quality.
Description
Technical field
The utility model relates to the Sewing machines field, relates in particular to a kind of backlash compensation spur gear.
Background technology
Sewing machines the phenomenons such as broken string and card cloth occur due to meeting in process, need again to squeegee circuit after occurring pausing when making.Existing compensation arrangement 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 penalty method affects crudy.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of backlash compensation spur gear of can reasonable compensation making circuit is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of backlash compensation spur gear, comprise driving gear and driven gear, described driving gear and driven gear link together, the one side that driven gear is combined with driving gear is provided with cavity, be provided with spring in described cavity, driving gear and driven gear centre are provided with connecting hole, be provided with locating hole by the edge, the two ends of spring is embedded in respectively in the locating hole of driving gear and driven gear.
Preferably, be provided with the screw thread locating hole on described driving gear.
Preferably, described screw thread locating hole has two.
Compared with prior art, usefulness of the present utility model is: this backlash compensation spur gear is simple in structure, can rationally control the eedle needle gage, and can guarantee that eedle resets, and does not affect processing, has improved sewing quality.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model backlash compensation spur gear structural representation.
In figure: 1, driving gear; 2, driven gear; 3, spring; 4, connecting hole; 5, locating hole;
