Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, specifically to a jacquard machine gearbox. Background Technology

[0002] Jacquard looms, as key pieces of equipment in textile machinery, weave complex patterns through the interlacing of warp and weft yarns and are widely used in fields such as apparel fabrics. With the textile industry developing towards high-speed and intelligent manufacturing, the precision requirements for the transmission system of jacquard looms are increasing. As the power transmission hub of the jacquard loom, the gearbox's performance directly affects weaving efficiency and fabric quality—the meshing precision of the driving and driven gears must meet the demands of hundreds of reciprocating motions per minute, while the lubrication condition inside the gearbox is a core element ensuring the stable operation of the transmission system.

[0003] Traditional jacquard machine gearboxes are typically maintained by disassembling the gearbox and then manually applying lubricant. Taking a certain model of jacquard machine as an example, a single disassembly requires removing more than 10 components, including the drive motor and transmission rod, which is time-consuming and requires specialized technicians. This not only leads to high downtime maintenance costs but also may cause the gearbox seals to age due to frequent disassembly, potentially leading to oil leaks. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a gearbox for a jacquard machine that allows for the addition of lubricating oil to the internal gears without disassembling the gearbox, and can seal the connections to prevent oil leakage during lubrication.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A jacquard machine gearbox includes a gearbox, a drive motor mounted on one side of the gearbox via a fixing block, a connecting rod mounted on the output end of the drive motor, a transmission rod connected to the other end of the connecting rod via a thread, a drive gear fixedly connected to one end of the transmission rod, the drive gear being located inside the gearbox, two sets of first bearings being provided on the outside of the connecting rod, an oil injection sleeve being fixedly connected to the outside of the two sets of first bearings, the connecting rod, the first bearings, and the oil injection sleeve forming an oil injection chamber, an oil injection port being fixedly connected to the outside of the oil injection sleeve, and oil injection holes being opened inside the connecting rod, the transmission rod, and the drive gear.

[0006] Preferably, a sealing part is provided at the connection between the connecting rod and the transmission rod, an oil injection pipe is threadedly connected to the outside of the oil injection port, and another sealing part is provided at the connection between the oil injection pipe and the oil injection port.

[0007] Preferably, the sealing part comprises a sealing gasket, a conical platform, and a conical groove adapted to the conical platform, wherein the sealing gasket is disposed at the connection between the conical platform and the conical groove.

[0008] Preferably, the gearbox is further provided with a driven gear that meshes with the driving gear. The meshing point of the driven gear on the driving gear is provided with an oil outlet that communicates with the oil filling hole. The oil filling chamber corresponds to the oil inlet that communicates with the oil filling hole.

[0009] Preferably, a plurality of positioning rings are fixedly connected inside the gearbox, and a support rod is installed inside the positioning ring, the support rod being connected to the driven gear.

[0010] Preferably, a limiting groove is provided inside the gearbox, and a gear ring is slidably connected inside the limiting groove, the gear ring meshing with the driven gear.

[0011] Preferably, the connecting rod has two sets of anti-leakage grooves on its outside, and a baffle is fixedly connected to one side of the first bearing, the baffle being adapted to the anti-leakage groove.

[0012] Preferably, the gearbox has an oil outlet and a limiting hole on one side, with the limiting hole located above the oil outlet.

[0013] Preferably, a limiting plate is fixedly connected to the outside of the oil injection pipe, and a connecting sleeve is movably installed on the outside of the oil injection pipe.

[0014] Preferably, the oil injection sleeve is connected to the gearbox.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a gearbox for a jacquard machine, which has the following advantages: This is used for gearboxes in jacquard machines. When using it, first open the oil outlet to drain any residual lubricating oil inside the gearbox, then close the oil outlet. Simultaneously, inject lubricating oil into the oil filling chamber through the oil filling hole. Then, guide the oil into the gear set through the oil filling hole inside the connecting rod and transmission rod, allowing the lubricating oil to lubricate the gear set. Observe whether the lubricating oil in the gearbox is flowing out from the limit hole. When the lubricating oil flows out from the limit hole, stop adding oil to the oil filling chamber. This achieves the function of adding lubricating oil to the gears without disassembling the gearbox.

[0016] This device is used in the gearbox of a jacquard machine. The sealing gasket is placed at the bottom of the tapered groove at one end of the transmission rod, and the tapered platform is aligned with the inside of the tapered groove. Since the connecting rod and the transmission rod are connected by threads, rotating the connecting rod causes the platform of the tapered platform of the connecting rod to press against the sealing gasket. The sealing gasket initially seals the lubricating oil, and at the same time, the inclined surface of the tapered platform is in close contact with the inclined surface of the tapered groove, further sealing the lubricating oil.

[0028] Example 1: This embodiment provides a gearbox for a jacquard machine, which has the following technical features.

[0029] Please see Figure 1-6 The jacquard machine gearbox includes a gearbox 1. A drive motor 2 is mounted on one side of the gearbox 1 via a fixing block. A connecting rod 3 is mounted on the output end of the drive motor 2. A transmission rod 4 is threaded to the other end of the connecting rod 3. A drive gear 5 is fixedly connected to one end of the transmission rod 4. The drive gear 5 is located inside the gearbox 1. Two sets of first bearings 31 are provided on the outside of the connecting rod 3. An oil injection sleeve 32 is fixedly connected to the outside of the two sets of first bearings 31. The connecting rod 3, the first bearings 31, and the oil injection sleeve 32 form an oil injection chamber 33. An oil injection port 321 is fixedly connected to the outside of the oil injection sleeve 32. Oil injection holes 6 are opened inside the connecting rod 3, the transmission rod 4, and the drive gear 5.

[0030] It should be noted that the transmission rod 4 passes through the gearbox 1, and the contact point between the transmission rod 4 and the gearbox 1 is connected by the second bearing 41.

[0031] Furthermore, a sealing part 8 is provided at the connection between the connecting rod 3 and the transmission rod 4, and an oil injection pipe 7 is threadedly connected to the outside of the oil injection port 321. Another sealing part 8 is provided at the connection between the oil injection pipe 7 and the oil injection port 321.

[0032] Furthermore, the sealing part 8 is provided by a sealing gasket 81, a conical platform 82, and a conical groove 83 adapted to the conical platform 82. The sealing gasket 81 is provided at the connection between the conical platform 82 and the conical groove 83.

[0033] It should be noted that the sealing gasket 81 is placed on the platform of the conical platform 82, and the sealing gasket 81 provides initial sealing. When the connecting rod 3 and the transmission rod 4 are installed together, the conical platform 82 at one end of the connecting rod 3 contacts the conical groove 83 at one end of the transmission rod 4, thereby further sealing the connection.

[0034] Furthermore, the gearbox 1 is equipped with a driven gear 51 that meshes with the driving gear 5. The meshing point of the driven gear 51 on the driving gear 5 is provided with an oil outlet that communicates with the oil filling hole 6. The oil filling chamber 33 corresponds to the oil inlet that communicates with the oil filling hole 6.

[0035] It should be noted that the lubricating oil enters the oil filling hole 6 through the oil inlet in the oil filling chamber 33, and then lubricates the gears through the oil outlet.

[0036] Furthermore, several positioning rings 13 are fixedly connected inside the gearbox 1, and support rods 14 are installed inside the positioning rings 13. The support rods 14 are connected to the driven gear 51.

[0037] It should be noted that when the driven gear 51 rotates, the support rod 14 connected to the driven gear 51 rotates inside the positioning ring 13, and at the same time, the positioning ring 13 positions the support rod 14.

[0038] Furthermore, a limiting groove 15 is provided inside the gearbox 1, and a gear ring 52 is slidably connected inside the limiting groove 15, which meshes with the driven gear 51.

[0039] It should be noted that the gear ring 52 is provided with a limiting block that matches the limiting groove 15.

[0040] Furthermore, the connecting rod 3 has two sets of anti-leakage grooves 34 on its outside, and a baffle 311 is fixedly connected to one side of the first bearing 31. The baffle 311 is adapted to the anti-leakage groove 34.

[0041] It should be noted that the baffle 311 is only fixed to the outer ring of the first bearing 31, and ensures that the first bearing 31 can work.

[0042] Furthermore, the gearbox 1 has an oil outlet 11 and a limiting hole 12 on one side, with the limiting hole 12 located above the oil outlet 11.

[0043] It should be noted that the level of the lubricating oil inside the gearbox 1 is limited by the limiting hole 12, and the lubricating oil inside the gearbox 1 is discharged through the oil outlet hole 11.

[0044] Furthermore, the oil injection pipe 7 is externally fixedly connected to a limiting plate 71, and the oil injection pipe 7 is externally movably installed with a connecting sleeve 72.

[0045] It should be noted that the oil inlet 321 has external threads, and the connecting sleeve 72 is adapted to the external threads of the oil inlet 321.

[0046] Furthermore, the oil injection sleeve 32 is connected to the gearbox 1.

[0047] It should be noted that the oil filling sleeve 32 is fixed to the gearbox 1 by the fixing block to prevent the oil filling sleeve 32 from rotating during operation.

[0048] Working principle: Place the sealing gasket 81 on the limiting plate 71 on one side of the oil injection pipe 7, then place the conical platform 82 of the oil injection pipe 7 into the conical groove 83 of the oil injection port 321, so that the end of the conical groove 83 abuts against the sealing gasket 81. Then connect the connecting sleeve 72 on the oil injection pipe 7 to the oil injection port 321 through threads. Lubricating oil is injected into the oil filling chamber 33 through the oil injection pipe 7 and the oil injection port 321. The lubricating oil enters the oil injection hole 6 through the oil inlet and then lubricates the gear through the oil outlet of the oil injection hole 6. The driving gear 5 meshes with the driven gear 51, and the oil outlet of the oil filling hole 6 is located at the meshing point of the driving gear 5 and the driven gear 51. Therefore, when the gear is working, it can also add lubricating oil to the gear inside the gearbox 1. The lubricating oil injection is stopped according to the height of the lubricating oil level inside the gearbox 1. When oil comes out of the limiting hole 12, the lubricating oil injection into the oil filling port 321 is stopped. Before adding lubricating oil to the gear inside the gearbox 1, the lubricating oil in the gearbox 1 is discharged through the oil outlet hole 11.

[0049] In summary, this gearbox for a jacquard machine operates by first opening the oil outlet 11 to drain the residual lubricating oil inside the gearbox 1, then closing the oil outlet 11. Simultaneously, lubricating oil is injected into the oil filling chamber 33 through the oil filling hole 6. The oil is then introduced into the gear set through the oil filling hole 6 inside the connecting rod 3 and transmission rod 4, thus lubricating the gear set. At the same time, it is observed whether the lubricating oil in the gearbox 1 flows out from the limiting hole 12. When the lubricating oil flows out from the limiting hole 12, the oil filling chamber 33 is stopped. This achieves the function of adding lubricating oil to the gears without disassembling the gearbox 1.

[0050] This is used in the gearbox of a jacquard machine. The sealing gasket 81 is placed at the bottom of the tapered groove 83 at one end of the transmission rod 4, and the tapered platform 82 is aligned with the inside of the tapered groove 83. Since the connecting rod 3 and the transmission rod 4 are connected by threads, the connecting rod 3 is rotated so that the platform of the tapered platform 82 of the connecting rod 3 hits the sealing gasket 81. The sealing gasket 81 initially seals the lubricating oil, and at the same time, the inclined surface of the tapered platform 82 is in close contact with the inclined surface of the tapered groove 83, further sealing the lubricating oil.
