[0002] Couplings are used to connect two shafts or a shaft and a rotating component, rotating together during the transmission of motion and power. For example, a self-aligning gear coupling disclosed in Chinese Patent Application No. CN202322178719.1 specifically includes: a first connecting body and a second connecting body. Both the inner walls of the first and second connecting bodies are fixedly provided with toothed grooves, which engage with a limiting groove and a limiting block. Simultaneously, two adjacent rotating plates are engaged inside a fourth groove. Then, through the interaction of a fixing block on the outer wall and a first bolt, the first and second connecting bodies are fixedly connected. The first gear engages with the toothed groove, and the locking pin is aligned with the second groove. By pressing the L-shaped plate, it rotates, thereby engaging with the locking block and the locking groove. Under the action of the second bolt, the connection of the coupling is made more stable. However, it has the following technical problems:

[0003] When connecting gears with different numbers of teeth, the entire first and second connecting bodies need to be replaced, resulting in a waste of resources. Furthermore, once the tooth grooves wear out, the entire coupling needs to be replaced, which easily increases the cost of use. Utility Model Content

[0004] To address the problem mentioned in the background section that the entire coupling needs to be replaced after the tooth grooves wear, this utility model provides the following technical solution:

[0005] A self-aligning gear coupling includes a first connecting block and a second connecting block for limiting the movement of two gears;

[0029] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0030] Please see Figures 1-8 This utility model provides a self-aligning gear coupling, including a first connecting block 100 and a second connecting block 200 for limiting the movement of two gears 10. The first connecting block 100 and the second connecting block 200 are fixed by bolts. A connecting shaft 11 is fixedly installed at one end of the gear 10, and a slot 12 is opened in the middle of the gear 10. Arc-shaped tooth sleeves 300 for locking the gear 10 are installed inside the first connecting block 100 and the second connecting block 200. Through the arrangement of the first connecting block 100, the second connecting block 200 and the arc-shaped tooth sleeves 300, the motion transmission between the two gears 10 is relatively stable. Furthermore, due to the detachable arc-shaped tooth sleeves 300, when the arc-shaped tooth sleeves 300 meshing with the gears 10 wear out, only the arc-shaped tooth sleeves 300 need to be replaced, without replacing the entire device, thereby saving on usage costs.

[0031] The first connecting block 100 includes a semicircular block 110, and the second connecting block 200 includes a semicircular block 210. The left and right sides of the semicircular block 110 are provided with mounting grooves 111 for placing the arc-shaped toothed sleeve 300, and the interior of the semicircular block 210 is provided with a cavity of the same size as the mounting groove 111 to facilitate the placement of the arc-shaped toothed sleeve 300. After the two arc-shaped toothed sleeves 300 are spliced ​​together, they are located outside the gear 10. The gear 10 can fully mesh with the arc-shaped toothed sleeves 300, so that when one of the gears 10 rotates, it drives the first connecting block 100 and the second connecting block 200, which are equipped with arc-shaped toothed sleeves 300, to rotate, thereby synchronously driving the gear 10 at the other end of the first connecting block 100 and the second connecting block 200 to rotate synchronously.

[0032] A channel 112 is provided in the middle of the semicircular block 110. The channel 112 has a T-shaped cross section and is connected to the mounting groove 111. The two ends of the channel 112 are respectively connected to the mounting grooves 111 on the left and right sides of the first connecting block 100. The outer wall of the semicircular block 110 is provided with an oil inlet 113 for conveying lubricating oil into the channel 112. A sealing plug 114 is installed at one end of the oil inlet 113 to seal the oil inlet 113. After the first connecting block 100 and the second connecting block 200 limit the gear 10, lubricating oil is injected into the oil inlet 113. The lubricating oil is conveyed into the channel 112 through the oil inlet 113 and finally flows into the two mounting grooves 111, so that the lubricating oil is between the gear 10 and the arc-shaped gear sleeve 300, thereby reducing friction and wear and increasing the service life of the arc-shaped gear sleeve 300. Sealing gaskets 120 are installed on both the left and right sides of the semicircular block 110 to seal the mounting grooves 111. Through the sealing of the sealing gaskets 120, the lubricating oil in the mounting grooves 111 cannot leak, and the lubricating oil can always play a lubricating role.

[0033] The mounting groove 111 has a positioning groove 115 in the middle of the groove cavity. Bolts 150 are installed at both ends of the semicircular block 110. The semicircular block 110 has holes on both sides for the bolts 150 to be inserted, and the holes extend into the positioning groove 115. A fixing block 310 is fixedly installed in the middle of the arc-shaped gear sleeve 300 to position the arc-shaped gear sleeve 300 in conjunction with the positioning groove 115. The fixing block 310 has a threaded hole 311 in the middle for fixing the arc-shaped gear sleeve 300 with a bolt 150. When installing the arc-shaped gear sleeve 300, the arc-shaped gear sleeve 300 is inserted into the groove of the mounting groove 111. When the fixing block 310 is engaged in the positioning groove 115, the arc-shaped gear sleeve 300 is positioned. When the gear 10 drives the arc-shaped gear sleeve 300 to rotate, the arc-shaped gear sleeve 300 drives the first connecting block 100 to rotate synchronously, so that the arc-shaped gear sleeve 300 at the other end of the first connecting block 100 drives the gear 10 to rotate synchronously. After the bolt 150 is screwed into the threaded hole 311, the arc-shaped gear sleeve 300 can be locked.

[0034] A square insert rod 130 is symmetrically installed on the left and right sides of the middle of the semicircular block 110, and the square insert rod 130 can slide left and right in the middle of the semicircular block 110. A slider 131 is fixedly installed on the end of the square insert rod 130 facing the middle of the semicircular block 110. The side of the slider 131 facing the second connecting block 200 is machined with an arc edge 132. A spring 140 is sleeved on the outside of the square insert rod 130. The spring 140 makes the two sliders 131 abut against each other. When the two sliders 131 abut against each other, one end of the square insert rod 130 does not extend into the mounting groove 111. A groove cavity for limiting the square insert rod 130 and the spring 140 is installed in the middle of the first connecting block 100, and a groove cavity for limiting the square insert rod 130 and the spring 140 is opened in the middle of the second connecting block 200, so that the square insert rod 130 can extend and retract smoothly.

[0035] The two ends of the semicircular block 210 are equipped with bolts 220 for fixing the arc-shaped gear sleeve 300 with threaded holes 311. Bolts 220 are screwed into threaded holes 311 to fix the arc-shaped gear sleeve 300 installed on both sides of the semicircular block 210. The middle of the semicircular block 210 is provided with threaded holes 211. Bolts 3230 for pushing the two sliders 131 are threaded in threaded holes 211. One end of bolts 3230 is rounded. When bolts 3230 are rotated, the rounded head of bolts 3230 presses against the two arc-shaped edges 132, so that the two sliders 131 synchronously drive the square insert rod 130 to insert into the slot 12, further positioning the gear 10.

[0036] This invention utilizes a detachable square insert 130 and an arc-shaped toothed sleeve 300, allowing for individual replacement of the square insert 130 and arc-shaped toothed sleeve 300 after wear, eliminating the need for complete replacement and reducing operating costs. Furthermore, this invention can be paired with multiple arc-shaped toothed sleeves 300 of different tooth counts and sizes to accommodate gears 10 of varying sizes, achieving effective transmission for gears 10 of different sizes. This invention has a wide range of applications and lower maintenance costs after wear. Lubricating oil is injected into the mounting groove 111 through the channel 112, slowing down the wear rate and increasing the service life of the arc-shaped toothed sleeve 300.

[0037] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
