Abstract
The utility model discloses a direct-driven motor for a chained sewing machine. The direct-driven motor comprises a head which is provided with a spindle; the spindle is fixedly connected with an auxiliary coupler which is fixedly connected with a main coupler through cooperation of grooves and projections; a cushion pad is arranged between end faces of the auxiliary coupler and the main coupler; the main coupler is fixedly connected with an output shaft of the motor; the motor is fixedly connected with the head; an input shaft of the motor is fixedly connected with a hand wheel. The direct-driven motor for the chained sewing machine has the advantages that integral production cost can be reduced, power transmission efficiency can be improved, and energy loss in a transmission process can be reduced.
Description
Technical field
The utility model relates to a kind of motor, is specifically related to a kind of direct-drive motor for chain type sewing machine.
Background technology
Existing chain type sewing machine, divides and can be divided into that manpower drives and two kinds of power drives by type of drive.Early stage Sewing machines drives by manpower mostly; Along with the development of social productive forces, this by manually driven mode low due to production efficiency, can not meet the needs of social production, the appearance of clutch motor is for Sewing machines drives and transfers power drive to reliable basis is provided from manpower.
The driving of modern industry Sewing machines is to provide power to export by clutch motor mostly, then by belt transmission, transmits power on Sewing machines, realizes the motion of Sewing machines.But such kind of drive is limited to bel-drivenn efficiency, power loss is very large; Secondly, belt and belt pulley belong to easily worn part, need often change, and cause production cost to increase; And because the development need of Sewing machines goes up vehicle positioning stop function accurately, and the reaction sensitivity of clutch motor is relatively poor, causing can not accurate stopping.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of direct-drive motor for chain type sewing machine, and it can realize the direct driving to chain type sewing machine.
For solving the problems of the technologies described above, the utility model for the technical solution of the direct-drive motor of chain type sewing machine is:
Comprise head 1, head 1 is provided with main shaft 2; Main shaft 2 is fixedly connected with from shaft coupling 14, from shaft coupling 14, achieves a fixed connection by groove with lead spindle 12 with protruding coordinating; Between shaft coupling 14 and the end face of lead spindle 12, be provided with cushion pad 13; Lead spindle 12 is fixedly connected with the output shaft of motor 5; Motor 5 is fixedly connected with head 1; The power shaft of motor 5 is fixedly connected with handwheel 10.
Described handwheel 10 is fixedly installed locator 8.
Described motor 5 is provided with control cabinet case 7.
The power shaft of described motor 5, output shaft and main shaft 2 are on same axis.
Described motor 5 is provided with safety switch.
The technique effect that the utility model can reach is:
The utility model not only can reduce whole production cost, and can improve the efficiency of power transmission, reduces the energy loss in transmitting procedure.
The utlity model has and go up vehicle positioning stop function accurately; Motor is provided with safety switch, and head starts realizes autostop.
The utility model is without realizing the transmission of Sewing machines by belt and belt pulley, thereby can effectively reduce production costs, and optimizes its transmission mechanism.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is that the utility model is for the decomposing schematic representation of the direct-drive motor of chain type sewing machine.
Description of reference numerals in figure:
1 is head, and 2 is main shaft,
3 is screw, and 4 is screw,
5 is motor, and 6 is screw,
7 is control cabinet case, and 8 is locator,
9 is handwheel hold-down screw, and 10 is handwheel,
11 is screw, and 12 is lead spindle,
13 is cushion pad, and 14 is from shaft coupling,

The specific embodiment
As shown in Figure 1, the utility model, for the direct-drive motor of chain type sewing machine, comprises head 1, and head 1 is provided with main shaft 2; Main shaft 2 is fixedly connected with from shaft coupling 14 by screw 3, from shaft coupling 14 and lead spindle 12 phase clampings, between shaft coupling 14 and lead spindle 12, is provided with cushion pad 13; Lead spindle 12 is fixedly connected with the output shaft of motor 5 by screw 4; Motor 5 is fixedly connected with head 1 by screw 6;
Motor 5 is provided with control cabinet case 7; Control cabinet case 7 is fixedly connected with motor 5 by screw 15;
The power shaft of motor 5 is fixedly connected with handwheel 10 by handwheel hold-down screw 9, and the end face of handwheel 10 is fixedly connected with locator 8 by screw 11;
The power shaft of motor 5, output shaft and main shaft 2 are on same axis.
Of the present utility model from shaft coupling 14 be arranged on main shaft 2 and with motor 5 output shafts on lead spindle 12 phase clampings, not only can facilitate and make motor 5 and being connected of main shaft 2 it be easy to install, cost is relatively low and be easy to change simultaneously.
Lead spindle 12 of the present utility model and cushion pad 13 is installed between shaft coupling 14, can effectively prevent that the moment of torsion that motor 5 produces while starting from damaging main shaft 2.
