The utility model is directly to be connected with the Sewing machines transmission main shaft by machine shaft, machine shaft is directly driven transmission main shaft, further say, that power output with motor is converted into rotatablely moving of transmission main shaft, therefore in this process, avoided the energy dissipation that causes because of belt transmission, and be provided with damping mechanism the structure quake amplitude is reduced, stability strengthens.
In the direct drive type transmission arrangement of above-mentioned Sewing machines, described mutual plug-in connection is: an end of the transmission main shaft that is connected with machine shaft radially is provided with groove or projection, one-body molded projection or the groove that has radially, the groove on the projection on the described machine shaft or groove and the transmission main shaft or protruding socket connection on the end face of the machine shaft that transmission main shaft connects.
In the direct drive type transmission arrangement of above-mentioned Sewing machines, described damping mechanism is to be coated on projection upward or " several " font of the equal thickness in the groove, and the front and back sides of " several " font is complementary with the inner surface of groove and the outer surface of projection respectively.
In the direct drive type transmission arrangement of above-mentioned Sewing machines, the outer surface of the joint portion of described transmission main shaft and machine shaft is fixed with the worm screw that drives the transmission Winder.
In the direct drive type transmission arrangement of above-mentioned Sewing machines, one of described worm screw is fixed by screws on the transmission main shaft, and the other end of worm screw is fixed by screws on the machine shaft.
The utility model compared to existing technology outstanding and useful technique effect is:
1, machine shaft of the present utility model directly drives machine spindle, and the energy loss of having avoided belt gear to cause has reduced production cost.
2, machine shaft of the present utility model and machine spindle are fixedly connected by radial protrusion and radial groove, and be simple in structure and steadiness is strong.
3, also be provided with damping structure between radial protrusion of the present utility model and the radial groove, further reduced vibration, strengthened the stability of using.
4, the utility model has also adopted the worm screw with the transmission Winder respectively machine spindle and machine shaft to be fixed, and has avoided main shaft and rotating shaft to produce displacement, has strengthened the firmness of structure.
