Abstract
The utility model provides a Main-axis transmission mechanism for sewing machine. It solves the problem that the existing main-axis transmission mechanism of sewing machine, the auxiliary axis and the main axis are put 3D-crossly. Therefore, they occupy a larger space. One end of the main axis connects with the power section. On the other end of the main axis, a crank connecting-rod component which joint to a pin-rod. The auxiliary axis is set by the side of the main axis. The auxiliary axis and the main axis connect each other via the transmission part which transmits the power from the main axis to the auxiliary axis. Jointing to the pin-fork and the thread picker, the transmission axis is set under the main axis. The transmission axis and the auxiliary axis are set vertically and stay in the same plane. Therefore the whole transmission mechanism occupies little space. By the way, the load pressure on the main axis is lightened via adding an auxiliary axis.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the spindle drive of a kind of transmission mechanism, particularly a kind of Sewing machines.
Background technology
Needle bar mechanism, string-hooking mechanism, thread take-up mechanism and feed mechanism are the 4 big principal organ that realize the sewing purpose, also are the most basic mechanisms of various special-purpose Sewing machiness.For some special machine, for example button holing sewing machine except that said mechanism, has also increased needle swinging mechanism.In button holing sewing machine, shank up-down mechanism, thread take-up mechanism and needle swinging mechanism are all driven by the rotation of main shaft.But the action inertia force of needle swinging mechanism and shank up-down mechanism is very big to the main axis rotation effect, makes main shaft be difficult to rotation at a high speed.
People explore for a long time for this reason, have proposed various embodiments.For example, Chinese patent literature discloses a kind of Sewing machines (application number: 200610105734.1), rotate by the electrical motor of sewing machine driving main shaft, the spindle crank fixing with main shaft drives the work of shank up-down mechanism, and and adopt gear drive between the countershaft that sets of main shaft crossings on different level and the main shaft, countershaft also rotates simultaneously on main axis rotation ground, drive the thread take-up tension lever swing of the thread take-up mechanism that is connected with this countershaft right-hand member linkage type, utilize the needle swinging mechanism that is connected with countershaft left end linkage type to make the shank swing simultaneously.Thereby reach the purpose that main shaft and countershaft separately drive shank up-down mechanism, needle swinging mechanism and thread take-up mechanism.
This scheme has been improved the operating rate of Sewing machines to a certain extent, but because its countershaft and main shaft crossings on different level, the space is bigger about taking.
Summary of the invention
The purpose of this utility model is at the problems referred to above, proposes a kind of rationally distributedly, takies the up and down little spindle drive in space.
The purpose of this utility model can realize by following technical proposal: a kind of spindle drive of Sewing machines, be arranged in the casing of Sewing machines, comprise the main shaft that the one end links to each other with power section, the main shaft other end has and is used for the crank rod assembly that is connected with shank, it is characterized in that, described main shaft sidepiece is provided with countershaft, between countershaft and the main shaft by the transmission of power of the main shaft driving member to countershaft being connected, the power transmission shaft that links to each other with thread take-up tension lever with pin pendulum fork is positioned at the main shaft bottom, have awl tooth one on the above-mentioned countershaft, have the awl tooth two that is meshed with awl tooth one on the above-mentioned power transmission shaft.
In the spindle drive of above-mentioned Sewing machines, described countershaft and spindle parallel setting.By countershaft is set, can solve the problem that part is too concentrated, be easy for installation and maintenance.When needs increase or reduce part, can only dismantle the countershaft at this part place, and to other parts without any influence.
In the spindle drive of above-mentioned Sewing machines, described driving member is the synchronous pulley one and the synchronous pulley two and the synchronous band that are connected on the countershaft that is connected on the main shaft, and band is enclosed within on synchronous pulley one and the synchronous pulley two synchronously.Band transmission synchronously has gearratio accurately, no slippage, and transmission is stable, can absorbing, noise is little, transmission efficiency height, advantage such as maintaining conveniently need not lubricated, and maintenance cost is low.
In the spindle drive of above-mentioned Sewing machines, described driving member is the travelling gear one and the travelling gear two that is connected on the countershaft that is connected on the main shaft, and travelling gear one is meshed with travelling gear two.
In the spindle drive of above-mentioned Sewing machines, the vertical setting of described power transmission shaft and both are in same plane with countershaft.Can dwindle the space hold of whole transmission mechanism like this.
Compared with prior art, the advantage of the spindle drive of this Sewing machines is:
1. rationally distributed, the space is little about taking.
2. by increasing a countershaft, alleviate the load pressure of main shaft.
