Generally be connected between the output shaft of dynamic power machine and the input shaft of work mechanism by coupling, on the direct drive sewing machine axle with electric machine main shaft between also be connected by coupling, in existing sewing machine, last profile of tooth belt wheel is distributed in the different axial positions of axle with coupling.Because last profile of tooth belt wheel and the driven device adjacent fixed of coupling on last axle, have so just increased the length of last axle, have also just increased fuselage simultaneously, have increased weight.
Summary of the invention
The purpose of this utility model is that the structure at the coupling of existing sewing machine can only be installed in relatively long going up on the axle, cause fuselage length and heavy problem to provide a kind of and can be installed in short going up on the axle, fuselage can be made the coupling of weak point and the sewing machine that is used in light weight.
The purpose of this utility model can realize by following technical proposal: a kind of coupling that is used for sewing machine, comprise the driven device of coupling and the motor coupler that is connected with electric machine main shaft of an end that axially are socketed in axle, the driven device of described coupling is connected with motor coupler, the outer cover of driven device of described coupling and motor coupler is connected to the profile of tooth belt wheel, and described upward profile of tooth belt wheel and the driven device of coupling are connected.
The utility model is used on the sewing machine transferring power between the pto and input shaft.Behind electric motor starting, electric machine main shaft drives motor coupler and rotates, motor coupler drives the driven device of coupling and rotates together, the driven device of coupling drives the axle of going up that is connected with it simultaneously and rotates with last profile of tooth belt wheel, last profile of tooth belt wheel drives and the belt rotation that be connected with lower shaft of socket thereon, thereby simultaneously power is input to axle and lower shaft.
In the coupling of above-mentioned sewing machine, driven device of described coupling and motor coupler plug by the double wedge of interlock intersected with each other.Motor coupler drives the coupling follower by the double wedge with the driven device X-bite of coupling and rotates.
In the coupling of above-mentioned sewing machine, be provided with the vibrationproof circle between the double wedge of driven device of described coupling and motor coupler.The vibrationproof circle can cushion the collision between the double wedge and reduce vibration.
Compared with prior art, advantage of the present utility model is:
1, go up the profile of tooth belt wheel and need not be directly installed on axle and be mounted on the driven device of coupling of axle and the motor coupler that the driven device of coupling plugs, effectively shortened last length, the while also shortened fuselage length, alleviated weight.
2, the vibrationproof circle adopts rubber ring, and vibration-isolating effect is better, and cost is low.
3, the motor coupler that plugs of driven device of coupling and the driven device of coupling is installed in the profile of tooth belt wheel, and the coupler structure compactness of this internal hidden type structure is more attractive in appearance.

Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 and Figure 2, the coupling of this sewing machine, comprise and axially be socketed in the motor coupler 4 that axle 1 the driven device 2 of coupling and an end are connected with electric machine main shaft 3, driven device 2 of coupling and motor coupler 4 plug by the double wedge 5 of interlock intersected with each other, the gap of double wedge 5 interlocks is provided with vibrationproof circle 6, the driven device 2 of coupling is connected to profile of tooth belt wheel 7 with the outer cover of motor coupler 4, and last profile of tooth belt wheel 7 is connected with the driven device 2 of coupling.
When the utility model is in running order, behind the electric motor starting, electric machine main shaft 3 drives motor coupler 4 and rotates, double wedge 5 with driven device 2 X-bites of coupling on the motor coupler 4 drives driven device 2 rotations of coupling, the driven device 2 of coupling drives the axle 1 of going up that is connected with it simultaneously and rotates with last profile of tooth belt wheel 7, last profile of tooth belt wheel 7 drive sockets thereon and the belt that is connected with lower shaft rotate, thereby power is imported lower shaft.
As Fig. 1, Fig. 3, Fig. 4 and shown in Figure 5, one end of the driven device 2 of coupling is socketed on the axle 1, the other end is circumferentially with three evenly distributed double wedges 5, and an end of motor coupler 4 connects the other ends with electric machine main shaft 3 and is provided with and 3 suitable evenly distributed double wedges 5 of the double wedge 5 of the driven device 2 of coupling.Double wedge 5 by these interlocks intersected with each other between driven device 2 of coupling and the motor coupler 4 plugs.There are the gap in the double wedge 5 of X-bite and double wedge 5 with electric machine main shaft, are provided with vibrationproof circle 6 in the gap.
