The utility model discloses changed original connected mode that the motor passes through shaft coupling and upper shaft of directly driving, the cancellation shaft coupling directly drives and adopts a synchronous pulley lug connection between motor and the upper shaft, simultaneously with the antifriction bearing direct mount on a synchronous pulley, compact structure like this, simple to operate, greatly increased the interior space of aircraft nose, satisfied some special sewing machine's demand.
Description
Technical field
The utility model relates to a kind of Sewing machines, is specifically related to a kind of direct driving motor transmission mechanism of Sewing machines.
Background technology
The transmission mechanism of general traditional direct driving motor Sewing machines, the kind of drive of its mechanism adopts shaft coupling to connect.
See Fig. 1, its drive mechanism is: direct driving motor 1 utilizes fillister head screw 12 to fix with one end of shaft coupling 11, the other end fillister head screw 12 of shaft coupling 11 is fixedly connected with upper axle 8, synchronous pulley 13 is fixed on upper axle 8 by screw 4, utilize Timing Belt 6 by synchronous pulley 13 and the synchronous pulley be fixed on lower shaft 9 (under) 7 to couple together.
The transmission implementation procedure of above-mentioned conventional sewing machine is: the power of direct driving motor 1 drives upper axle 8 to rotate by shaft coupling 11, and drive synchronizing wheel 13 utilize Timing Belt 6 connect synchronous pulley (under) 7 drive lower shafts 9 rotate, form whole transmission mechanism.
Above-mentioned transmission mechanism need be provided with rolling bearing 2 and shaft coupling 11 between synchronous pulley 13 and direct driving motor 1, and number of parts causes the volume ratio of mechanism own comparatively large more, takies the space in head of sewing machine, and installs inconvenient.
Utility model content
The technical problems to be solved in the utility model there is provided a kind of compact conformation, easy for installation, the direct driving motor transmission mechanism that reduces a kind of Sewing machines of Sewing machines volume.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of transmission mechanism of Sewing machines, described transmission mechanism comprises casing, direct driving motor, upper axle, lower shaft and Timing Belt, described direct driving motor is directly connected by the first synchronous pulley with upper axle, described lower shaft is provided with the second synchronous pulley, and described first synchronous pulley is connected by Timing Belt with the second synchronous pulley.
In a preferred embodiment of the present utility model, described upper axle and lower shaft are separately positioned on casing.
In a preferred embodiment of the present utility model, one end of described first synchronous pulley is fixed by screws on axle, and the other end of described first synchronous pulley is fixedly connected with direct driving motor by holding screw.
In a preferred embodiment of the present utility model, described first synchronous pulley is provided with rolling bearing.
The beneficial effects of the utility model are:
The utility model changes the connected mode of original direct driving motor by shaft coupling and upper axle, cancel shaft coupling, the first synchronous pulley is adopted directly to be connected between direct driving motor with upper axle, rolling bearing is directly installed on the first synchronous pulley simultaneously, such compact conformation, easy for installation, considerably increase the space in head, meet the demand of some special Sewing machines.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of existing Sewing machines transmission mechanism;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 2, the direct driving motor transmission mechanism of the Sewing machines that the utility model provides, wherein casing 100 is respectively arranged with axle 110 and lower shaft 120, direct driving motor 200 is fixedly connected with by holding screw 310 one end with the first synchronous pulley 500, the other end of the first synchronous pulley 500 is fixed on upper axle 110 by screw 320, is arranged on the first synchronous pulley 500 by rolling bearing 400 simultaneously.
Lower shaft 120 is provided with the second synchronous pulley 600, between the second synchronous pulley 600 and the first synchronous pulley 500, is provided with Timing Belt 700.
Specific works process of the present utility model is as follows:
When direct driving motor 200 works, the upper axle 110 directly connected by the first synchronous pulley 500 is with it driven to rotate, by Timing Belt 700, rotary power is delivered on the second synchronous pulley 600 when upper axle 110 rotates, second synchronous pulley 600 can drive lower shaft 120 to rotate together when rotating, thus achieve direct driving motor 200 and rotated by the first synchronous pulley 500 upper shaft direct drived 110, and be synchronized with the movement with lower shaft 120 by the upper axle 110 of Timing Belt 700 realization, complete the whole transmission process of Sewing machines.
Like this by above-mentioned enforcement, change the connected mode of original direct driving motor by shaft coupling and upper axle, eliminate shaft coupling, directly be connected by adopting the first synchronous pulley 500 between direct driving motor 200 with upper axle 110, rolling bearing 400 is directly installed on the first synchronous pulley 500, such compact conformation simultaneously, easy for installation, considerably increase the space in head, meet the demand of some special Sewing machines.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
