Description

The power transmission device of running cam of a jacquard machine

The present invention relates to a drive device for a plurality of timing gears in cam drive power transmission of a narrow loom, and more particularly, mechanical friction noise generated when the cam rotates while safely transmitting power to a heald and a lever formed on the narrow loom. And a cam driving power transmission of a narrow loom which can safely rotate the cam by transmitting the rotational force of the drive motor to a plurality of timing gears and timing belts fixed to a rotating shaft so as to prevent abrasion. It is about.

In general, in order to rotate the healds attached to the conventional narrow loom, a separate gear box is formed to transmit the rotational force of the motor.

In addition, the method of transmitting the rotational force of the motor rotating at a high speed to the cam has a method of engaging the bevel gears with each other inside the gearbox as shown in FIG. 5 (a). Also, as shown in FIG. It is widely used as a method of transmitting the rotational force of the motor to the cam in an assembled state inside the box.

However, the problem caused by the use of the mechanism made in this way is that it is formed integrally with the gear assembled inside the gearbox, with the cumbersome disadvantage of having to periodically replace or replenish the lubricating oil and oil charged inside the gearbox. Since the shaft protrudes to the outside and rotates at high speed, a part of the lubricant filled inside the gearbox flows into the gap between the waterproof Teflon and the packing member, and leakage occurs periodically on the projected shaft surface. There was a problem polluting the surroundings and products.

In addition, various gears formed inside the gearbox have a structure in which the shaft of the shaft interlocking with the driving motor shaft is engaged at a right angle of 90 ° due to the characteristics of the narrow loom. There is a disadvantage working.

The present invention has been made in order to solve the above problems, to provide a drive device of a plurality of timing gears that can transmit power to the heald and lever formed in the narrow loom of the driving motor more safely and simply. have.

In order to achieve the above object, a plurality of timing gears fixed to a rotating shaft which is interlocked with the driving force received by the driving motor and another plurality of timing gears formed at a right angle to each other are twistedly interconnected by a timing belt to improve the rotational force of the driving motor. In the cam drive power transmission of the narrow loom to transmit and rotate the cam safely, it is intended to implement a drive device of a plurality of timing gears.

The present invention is configured to transfer power by connecting a plurality of timing gears fixed to the rotating shaft of the drive motor and a timing gear fixed to the cam shaft with a plurality of timing belts.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment of the present invention as follows.

1 is a front view showing a driving device of a plurality of timing gears according to the present invention, Figure 2 is a side view showing a driving device of a plurality of timing gears according to the present invention, Figure 3 is a state in which the main portion of the present invention is assembled and operated 4 (a) and (b) are assembled perspective views taken from a drive device of a plural timing gear which is the main part of the present invention, and FIG. 5 (a) (b) shows a cam drive device of a conventional narrow loom. The assembled perspective view shown.

First, the rotation of the heald 10 attached to the narrow loom (not shown) operates the heald 10 up and down by the operation of the cam 12 and the lever 11 fixed to the camshaft 13.

And the rotation of the cam 12 fixed to the camshaft 13 is configured to be made by the rotation of the plurality of timing gear 21.

In this case, the plurality of timing gears 21 are configured to be connected to the timing belt 20 by forming a plurality of timing gears 21 fixed to the rotation shaft 24 of the driving motor 17 at a 90 ° angle. .

In this situation, the plurality of timing gears 21 and the plurality of timing gears 21 connected to the camshaft 13 fixed to the shaft 22 interlocked with the rotational force of the driving motor 17 are geared. The modules are formed identically.

Therefore, in order to transfer the rotational force of the drive motor 17 to the cam shaft 13, it is preferable to interconnect with the timing belt 20.

The timing belt 20 is twisted as shown in FIG. 1 and FIG. 2, but it does not generate a large tension due to the same module of the gear.

In addition, in order to efficiently transmit the rotational force of the driving motor 17, it is reasonable to form a plurality of timing gears 21 and timing belts 20, and the size and number of gears can be variously adjusted according to circumstances. Due to the characteristics of the timing belt 20, it is not slippery and noise is low, so that the high speed rotation can be continuously transmitted.

Referring to the operation and effects of the present invention made of the above configuration as follows.

First, the cam 12 and the timing gear 21 are integrally assembled to the cam shaft 13 assembled as shown in FIG. 3.

In addition, the cam 12 fixed to the camshaft 13 is assembled with the lever 11 connected to the heald 10, wherein the lever 11 may move up and down on the curved surface of the cam 12.

The rotation of the cam 12 operated in this way is 90 ° perpendicular to the plurality of timing gears 21 fixed to the camshaft 13 and the plurality of timing gears 21 fixed to the rotation shaft 24 of the drive motor 17. By connecting to the twisted timing belt 20 in the formed state to transmit the rotational force of the drive motor 17 to the cam 12 will be able to safely operate the lever (11).

That is, only a plurality of timing belts 20 are simply connected in a state where a plurality of timing gears 21 formed as shown in FIG. 4A are assembled to the cam shaft 13 and the rotation shaft 24 of the driving motor 17. To complete the assembly work.

In addition, depending on the situation, power may be transmitted to one timing gear 21 as shown in FIG.

Therefore, it is possible to drive the cam of the narrow loom without a drive device made of a complicated configuration such as a conventional gearbox.

The present invention described above is possible to those skilled in the art to which the present invention belongs to various modifications and changes can be made within the scope without departing from the technical spirit of the present invention in the foregoing embodiments and the accompanying drawings. It is not limited.

The present invention does not require a gearbox, which is a separate drive device in which bevel gears and worm gears are assembled, and can significantly reduce the cost of manufacturing narrow looms. In addition, mechanical friction noise and lubricating oil in the gearbox flow down. Not only does the phenomenon occur, the product can be manufactured more safely, and the work environment is pleasant, and it has the characteristics of increasing production efficiency.
