Abstract
The utility model provides a transmission mechanism of a sewing machine, and the transmission mechanism belongs to the technical field of sewing machines. The transmission mechanism of the sewing machine solves the problems of the prior art that the assembly difficulty of a gear is great, a needle is easily collided and the like, comprises a sewing machine body, a stand, an upper shaft of the sewing machine arranged in the sewing machine body, and a lower shaft of the sewing machine arranged in the stand, and is characterized in that the upper shaft of the sewing machine is driven by a driving motor, synchronous belt pulleys are correspondingly arranged on the upper shaft and the lower shaft; the upper shaft drives the lower shaft through a synchronous belt; and the ratio of the diameters of the reference circles of the synchronous belt pulleys on the upper shaft and the lower shaft is 2:1. The transmission mechanism of the sewing machine has the advantages of simplicity, practicality, precision and stability in processing and the like.
Description
Technical field
The utility model belongs to the sewing machine technique field, refers in particular to a kind of transmission mechanism of Sewing machines.
Background technology
The transmission mechanism of Sewing machines typically refers to being in transmission connection between the axle and lower shaft on the Sewing machines, in the Sewing machines actual moving process, upper axle is not identical with the rotating speed of lower shaft, and its rotating speed is to satisfy when Sewing needles once pumps, and rotating shuttle angular speed rotated for two weeks.
At present, Sewing machines of the prior art normally on the Sewing machines axle by belt pulley transmission sewing machine feed lifting axle, feed lifting rock shaft is again by the gear drive lower shaft, there is following problem in this structure: the one, and higher to the required precision of gear, and structure is comparatively complicated, required part is also more, caused part processing and assembly difficulty large, have influence on performance and the maintenance of the complete machine of Sewing machines, increased production cost, the 2nd, wear and tear after long-term the use because gear is intermeshing, then have influence on lower shaft and upper axle speed ratio, easily produce the striker phenomenon, incured loss through delay the duration, reduced production efficiency.
Summary of the invention
The purpose of this utility model provides the transmission mechanism that directly drives a kind of Sewing machines of lower shaft by upper axle.
The purpose of this utility model is achieved in that a kind of transmission mechanism of Sewing machines, comprise Sewing machines body, support and be positioned at the lower shaft of sewing machine of axle, support on the Sewing machines of body, axle is to drive by drive motors on the described Sewing machines, it is characterized in that: be equipped with accordingly synchronous pulley on described upper axle, the lower shaft, upper axle drives lower shaft by Timing Belt, and the ratio of the synchronous pulley on the described upper axle and the reference diameter of the synchronous pulley on the lower shaft is 2: 1.
Principle of the present utility model is directly to drive lower shaft by upper axle to rotate, rotating ratio according to diaxon is different, adopt the synchronous pulley of corresponding reference diameter, and then connect by toothed belt transmission, its sync rates of the upper and lower axle of this transmission mechanism is high, therefore in Sewing machines work process, process more accurate.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utility model is to adopt upper axle directly to drive lower shaft by Timing Belt, synchronous pulley, has omitted original gear drive or link transmission, and therefore the sync rates of upper and lower axle is high, Sewing machines precision machining, stable.
2, synchronous pulley of the present utility model is the synchronous pulley with fixed size ratio, has guaranteed that the rotating ratio of upper axle and lower shaft is 2: 1, has avoided striker, card pin work delays.
3, of the present utility model simple and practical, easy to operate.
Description of drawings
Fig. 1 is structure function sketch of the present utility model.
Fig. 2 is that the utility model is installed in the structural representation on the Sewing machines.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
A kind of transmission mechanism of Sewing machines, comprise Sewing machines body 1, support 2 and be positioned at axle 3 on the Sewing machines of body, lower shaft of sewing machine 4 in the support, axle 3 is to drive by drive motors on the described Sewing machines, described upper axle 3, be equipped with accordingly synchronous pulley 5 on the lower shaft 4, upper axle 3 drives lower shaft 4 by Timing Belt, the ratio of the synchronous pulley 51 on the described upper axle and the reference diameter of the synchronous pulley 52 on the lower shaft is 2: 1, principle of the present utility model is directly to drive lower shaft 4 by upper axle 3 to rotate, rotating ratio according to diaxon is different, adopt the synchronous pulley of corresponding reference diameter, and then connect by toothed belt transmission, on this transmission mechanism, its sync rates of lower shaft is high, therefore in Sewing machines work process, process more accurate.
Above-described embodiment is preferred embodiment of the present utility model only, is not to limit according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
