Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ear yarn assembly for water jet looms, and specifically to a durable ear yarn disc. Background Technology
[0002] During the operation of a water-jet loom, the ear yarn device tightly twists the weft yarn through a twisting action to ensure the tightness of the fabric selvage. Simultaneously, related components such as the ear yarn wheel, ear yarn gear, and tension adjustment mechanism work together to ensure the stability and tension consistency of the ear yarn during the twisting process. The sensing and control system monitors and adjusts relevant parameters in real time to ensure the normal operation of the loom and the quality of the fabric. When the ear yarn disc drives the ear yarn wheel to rotate at high speed, uneven force leads to relatively severe wear on the inner shaft of the gear, resulting in downtime for maintenance and affecting work efficiency. Therefore, this utility model provides a durable ear yarn disc. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] like Figures 1 to 3 As shown, a durable ear wire spool includes a weaving gear 1, which comprises a gear disk 15 and a gear edge 16. The gear edge 16 is detachably connected to the edge of the gear disk 15 by bolts. The gear edge 16 is made of engineering plastic, which is high-strength, lightweight, and replaceable. When the teeth of the weaving gear 1 wear down, only the gear edge 16 needs to be replaced, thus reducing costs.
[0022] The selvage gear 1 has a first through hole at its center, and a first ball bearing 2 is installed inside the first through hole. A central shaft 3 is inserted into the center of the first ball bearing 2. To improve stability, there are two first ball bearings 2, which are arranged side by side in the first through hole.
[0023] The first end of the central shaft 3 is flush with the first side of the selvage gear 1, and the second end extends toward the second side of the selvage gear 1. A central gear 6 is fitted onto the segment of the central shaft 3 located on the second side of the selvage gear 1. The central gear 6 is fixedly fitted to the central shaft 3 and rotates synchronously.
[0024] Two second through holes are symmetrically opened on both sides of the first through hole on the selvage gear 1. A second ball bearing 4 is installed in the second through hole, and a planetary gear shaft 5 is inserted in the center of the second ball bearing 4. To improve stability, there are two second ball bearings 4, which are arranged side by side in the second through holes.
[0025] The first end of the planetary gear shaft 5 is connected to the connecting disc 7 located on the first side of the selvage gear 1, and the second end extends toward the second side of the selvage gear 1. A planetary gear 8 is fitted onto the segment located on the second side of the selvage gear 1. The planetary gear 8 does not mesh with the central gear 6. The connecting disc 7, the planetary gear shaft 5, and the planetary gear 8 rotate synchronously.
[0026] The second side of the selvage gear 1 is provided with planetary idler gears 9, which mesh with both the central gear 6 and the planetary gear 8. There are two planetary idler gears 9, which are sleeved around the third ball bearing 10. An idler gear shaft 11 is inserted into the center of the third ball bearing 10. The first end of the idler gear shaft 11 is connected to the selvage gear 1, and the second end extends towards the second side of the selvage gear 1. The selvage gear 1 rotates under the drive of an external drive mechanism. The central shaft 3 is fixed, and the central gear 6 rotates relative to the selvage gear 1, driving the planetary gear 8 to rotate. The planetary gear 8 drives the connecting disc 7 to rotate. Simultaneously, the connecting disc 7 revolves under the drive of the selvage gear 1, thereby causing the lug disc connected to the connecting disc 7 to revolve and rotate.
[0027] The second side of the selvage gear 1 is provided with a connecting and fixing plate 12, which is connected to the central shaft 3, the planetary gear shaft 5, and the idler gear shaft 11. The connecting and fixing plate 12 is rotatably connected to the central shaft 3 via a fourth ball bearing 13, rotatably connected to the planetary gear shaft 5 via a fifth ball bearing 14, and fixedly connected to the idler gear shaft 11. Specifically, the fourth ball bearing 13 and the fifth ball bearing 14 are both disposed in through holes opened on the connecting and fixing plate 12 and are fitted onto the central shaft 3 and the planetary gear shaft 5. The idler gear shaft 11 is detachably fixed to the selvage gear 1 and the connecting and fixing plate 12 by bolts for easy disassembly and maintenance. To avoid the connecting and fixing plate 12 affecting the selvage gear 1, the edge of the connecting and fixing plate 12 does not extend beyond the edge of the selvage gear 1.
[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
