Description

Double output traversing worm gear box

technical field

The invention relates to a Raschel warp knitting machine, in particular to a turbine box which provides different traverse amounts for the bar of the Raschel warp knitting machine.

Background technique

Raschel warp knitting machine is a type of warp knitting machine characterized by an angle of more than 140° between the fabric pulling direction and the needle bar plane layer. It is often used to weave curtains, tablecloths, bedspreads, blankets, lace ribbons, fishing nets, packaging Warp knitted fabrics with complex organization structures such as bags.

The bar of the warp knitting machine is an important part of the warp knitting fabric part, and different bars need to be provided with different traverse amounts during the weaving process of the warp knitting machine. Because the output of the main shaft of the warp knitting machine is the rotational speed, the rotational speed of the main shaft must first be formed into different rotational speed outputs, and then the different rotational speed outputs are converted into different traverse amounts of the bar.

Contents of the invention

The technical problem to be solved by the present invention is to realize two different rotational speed outputs through one worm gear box.

In order to solve the above-mentioned technical problems, the double-output traversing worm gear box of the present invention includes a base on which a worm gear box is fixed, and a first worm wheel cavity and a second worm wheel cavity are opened in the worm wheel box, and the first worm wheel An assembly of the first worm wheel and the first worm is arranged in the box, and an assembly of the second worm wheel and the second worm is arranged in the cavity of the second worm gear, and the output speed ratios of the two groups of worms are different.

The first worm wheel is rigidly and fixedly connected to the solid shaft, the second worm wheel is rigidly and fixedly connected to the hollow shaft, and the hollow shaft is connected to the solid shaft and the worm gear box through a bearing.

The output end of the solid shaft is connected with the faceplate; the output end of the hollow shaft is connected with the knitting wheel.

After adopting the above structure, the worm gear box includes two worm gear chambers, and the combined output speed ratios of the worm gear and worm in the worm gear chambers are different, so the worm gear box can have two different speed outputs. In addition, through the cooperation of the solid shaft and the hollow shaft, the space of the whole device is reduced and the cost is saved.

detailed description

As shown in FIG. 1 , the double output traversing worm gear box of the present invention includes a base 1 on which a worm gear box 2 is fixed. The first worm gear cavity 4 and the second worm gear cavity 3 are opened in the described worm gear box, the assembly of the first worm wheel 8 and the first worm 7 is arranged in the first worm wheel box, and the second worm wheel is arranged in the second worm wheel cavity 3 6 and the assembly of the second worm 5, the output speed ratios of the two groups of worm gears are different. Here the input speed of the first worm 7 and the second worm 5 is consistent with the main shaft speed of the warp knitting machine, because the output speed ratio of the first worm group and the second worm group is different, so the first worm 8 and the second worm 6 The output speed is not the same, to achieve a speed input, two different speed output.

In order to transfer the output of the first worm wheel 8 and the second worm wheel 6 to the traverse amount of the warp knitting machine bar, it is necessary to connect the rotating shaft to the first worm wheel 8 and the second worm wheel 6 on the first worm wheel 8 and the second worm wheel 6. output at different speeds. However, if the first worm wheel 6 and the second worm wheel 8 are respectively connected to a solid shaft output, the positions of the two solid shafts will inevitably be staggered, so that more space is needed to place the two solid shafts, and the production cost will be increased. Here, in order to further save space and cost, the first worm wheel 8 is rigidly fixedly connected to the solid shaft 9, and the second worm wheel 6 is rigidly connected to the hollow shaft 10. Here, the rigidly fixed connection is fixed by means of a keyway. The rotational speed of the solid shaft 9 is the same as that of the first worm wheel 8 like this, and the rotational speed of the hollow shaft 10 is the same as that of the second worm wheel 6, so that the hollow shaft 10 and the solid shaft 9 are output at different rotational speeds. The hollow shaft 10 is sleeved on the outside of the solid shaft 9, and the hollow shaft 10 is connected to the solid shaft 9 and the worm gear box 2 through bearings, that is, the inside of the hollow shaft 10 is connected to the solid shaft 9 through the first bearing 11 and the second bearing 12. Connection, spaced between the first bearing 11 and the second bearing 12; the outer side of the hollow shaft 10 is connected with the worm gear box 2 through the third bearing 13. In this way, the hollow shaft 10 and the solid shaft 9 belong to concentric shafts, which is equivalent to using only one solid shaft, which saves space and saves costs; in addition, the hollow shaft 10 and the solid shaft 9 are connected by bearings to ensure that the hollow shaft 10 and the solid The shaft 9 is output at different rotational speeds.

Further, in order to convert the different output rotational speeds on the hollow shaft 10 and the solid shaft 9 into traverse amounts on different comb bars. A faceplate 15 is connected to the output end of the solid shaft 9, and the faceplate 15 can convert the rotational motion of the solid shaft 9 into the lateral movement of the bar; in addition, the output end on the hollow shaft 10 is connected with a knitting pattern Wheel 14, four grooves are arranged on the braided flower wheel 14, four cover chain blocks can be installed, and the chain blocks can convert the rotary motion of hollow shaft 9 into the traverse amount of bar. Because the output speeds of the hollow shaft 10 and the solid shaft 9 are different, so the traverse amount of the comb bars connected to them is also different.

Of course, the first worm wheel and the solid shaft, and the second worm wheel and the hollow shaft in the present invention can also adopt other practical fixing methods, and such transformations all fall within the protection scope of the present invention. Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to these embodiments without departing from the principles and principles of the present invention. substance. The scope of the invention is limited only by the appended claims.
