The purpose of this utility model is achieved in that a kind of synchronous belt drive mechanism, comprise the first regulating wheel, Timing Belt and for being fixed on the upper spindle synchronous wheel on upper main shaft, first regulating wheel is arranged on the first regulating wheel and installs on fixed axis, first regulating wheel, Timing Belt and upper spindle synchronous wheel form V belt translation, described Timing Belt is double cog synchronous belt, the outside of this double cog synchronous belt is affixed on for the lower rotary shuttle shaft synchronizing wheel be arranged on lower rotary shuttle shaft, and double cog synchronous belt forms cornerite on lower rotary shuttle shaft synchronizing wheel, described upper spindle synchronous wheel is made to form transmission by this double cog synchronous belt and lower rotary shuttle shaft synchronizing wheel.
On the basis of such scheme and as the preferred version of such scheme: also comprise the second regulating wheel and the second regulating wheel installs fixed axis, this second regulating wheel is arranged on the second regulating wheel and installs on fixed axis, described second regulating wheel, upper spindle synchronous wheel and the first regulating wheel are three angular range assemblings, and described double cog synchronous belt is also stretched on the second regulating wheel.
On the basis of such scheme and as the preferred version of such scheme: the low points on lower rotary shuttle shaft synchronizing wheel is lower than the high site of the first regulating wheel.
On the basis of such scheme and as the preferred version of such scheme: described double cog synchronous belt is that glass fibre is strength layer and its outer endless belt coated with polyurethane.
On the basis of such scheme and as the preferred version of such scheme: upper spindle synchronous wheel adopts aluminum alloy materials to make.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the double cog synchronous belt in synchronous belt drive mechanism of the present utility model directly drives lower rotary shuttle shaft synchronizing wheel to rotate, and lower rotary shuttle shaft and upper main shaft can be made to be formed rotate backward, have the advantages that transmission accuracy is high.Moreover this synchronous belt drive mechanism also has the feature that transmission progression is few, transmission efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1;
This gives a kind of synchronous belt drive mechanism, transmission of torque is given lower rotary shuttle shaft 2 by this synchronous belt drive mechanism by upper main shaft 1, and also can achieve lower rotary shuttle shaft 2 relative to upper main shaft 1 in rotating backward.It comprises lower rotary shuttle shaft synchronizing wheel 3, first regulating wheel 4, first regulating wheel and installs fixed axis (figure does not show), double cog synchronous belt 5 and take turns 6 for the upper spindle synchronous be fixed on upper main shaft.First regulating wheel 4 is arranged on the first regulating wheel and installs on fixed axis.During use, the first regulating wheel is installed fixed axis and is satisfied with in Sewing machines, make the first regulating wheel rotatable relative to Sewing machines.First regulating wheel 4, double cog synchronous belt 5 and upper spindle synchronous wheel 6 forms V belt translation, and double cog synchronous belt 5 is stretched on spindle synchronous wheel 6 and the first regulating wheel 4, enables this double cog synchronous belt pass on power.The outside of this double cog synchronous belt 5 is affixed on for the lower rotary shuttle shaft synchronizing wheel 3 be fixed on lower rotary shuttle shaft 2, and double cog synchronous belt 5 is formed with cornerite on lower rotary shuttle shaft synchronizing wheel 3, described upper spindle synchronous wheel 6 is made to form transmission by this double cog synchronous belt 5 with lower rotary shuttle shaft synchronizing wheel 3.
Be understandable that, the lateral surface of the double cog synchronous belt in this synchronous belt drive mechanism is directly connected with lower rotary shuttle shaft synchronizing wheel, and to make upper main shaft drive lower rotary shuttle shaft to rotate backward, its transmission progression is few, and transmission efficiency is high.
Preferably, this synchronous belt drive mechanism is also provided with described regulating wheel and comprises the second regulating wheel 7 and the second regulating wheel and install fixed axis 8.This second regulating wheel 7 is arranged on the second regulating wheel and installs on fixed axis 8.Described second regulating wheel 7, upper spindle synchronous wheel 6 and the first regulating wheel 4 are in three angular range assemblings, and described double cog synchronous belt 5 is also stretched on the second regulating wheel 7, specifically, as shown in fig. 1, double cog synchronous belt is stretched on spindle synchronous wheel, the first regulating wheel and the second regulating wheel, and its three is in three angular range layouts.Second regulating wheel 7 is used for regulating double cog synchronous belt 5 tensioning.First regulating wheel 4 is used to make double cog synchronous belt better to fit lower rotary shuttle shaft synchronizing wheel, makes this double cog synchronous belt have larger cornerite on lower rotary shuttle shaft synchronizing wheel, to improve the bearing capacity of this toothed belt transmission.In order to increase cornerite further, adjust the position of the first regulating wheel 4 relative to lower rotary shuttle shaft synchronizing wheel 3, as shown in FIG., the low points 31 on lower rotary shuttle shaft synchronizing wheel 3 is lower than the high site 41 of the first regulating wheel 4.
In the present embodiment, double cog synchronous belt 5 is strength layer and its outer endless belt coated with polyurethane for glass fibre.It is accurate that it has transmission, little to axle active force, compact conformation, oil resistant, the advantages such as ABRASION RESISTANCE is good, and ageing resistace is good.Upper spindle synchronous wheel 6 adopts aluminum alloy materials to make.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
