Technical Field

[0001] The utility model relates to the field of gears, in particular to a gear forging. Background Art

[0002] Gear forgings refer to gear blanks formed through a forging process. There are teeth on the rim of the gear forgings, and they can continuously mesh to transmit motion and power. Gears, as power transmission parts, are commonly seen in people's daily lives and are widely used in mechanical equipment.

[0003] According to the Chinese authorized patent announcement number: CN219866139U, a gear forging that is not easy to loosen is disclosed, including a first gear assembly, a wear-resistant wrapping layer, a gear connecting mechanism and a second gear assembly, the outer wall of the first gear assembly is provided with a wear-resistant wrapping layer, and the side of the wear-resistant wrapping layer is provided with a gear connecting mechanism, the side of the first gear assembly is provided with a second gear assembly, the gear connecting mechanism includes a tooth block, a protrusion and a second wear-resistant layer, and the side of the tooth block is provided with a protrusion, and the surface of the tooth block is provided with a second wear-resistant layer. The gear forging which is not easy to loosen, the first wear-resistant layer and the second wear-resistant layer are both made of diamond wear-resistant layer, and the wear-resistant layer is coated in the tooth gaps of multiple tooth blocks and the toothed disc. Then, since each tooth block of the gear is chamfered and the side raised bumps are set, the gear forging can be more tightly matched. Finally, the shaft hole is set to cooperate with the positioning groove to avoid shaking and deviation during installation. However, the gear forging still has shortcomings. With the long-term use of the gear forging, when the connecting parts between the gear forging and the transmission shaft are worn or damaged, the gear forging often needs to be replaced as a whole, which is not only time-consuming and labor-intensive, but also increases maintenance costs. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a gear forging, which solves the problem that when the connecting parts between the gear forging and the transmission shaft are worn or damaged after long-term use, the gear forging often needs to be completely replaced, which is not only time-consuming and labor-intensive, but also increases maintenance costs.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a gear forging, including a gear forging ring, a plurality of forging grooves are annularly distributed inside the gear forging ring, and a connection limit mechanism is arranged inside each of the plurality of forging grooves, the connection limit mechanism includes a locking screw, an adjusting nut, a limit stop column and anti-slip grooves, the locking screw is arranged inside the forging groove, and the inner end of the locking screw is penetrated inside the gear forging ring, a threaded groove is penetrated between the gear forging ring and the locking screw, the outer end of the locking screw is fixedly connected with an adjusting nut, a limit stop column is arranged on the outer side of the adjusting nut, and the limit stop column is fixedly connected to the gear forging ring.

[0006] Preferably, the outer surface of the adjusting nut is provided with a plurality of anti-slip grooves.

[0007] Preferably, a shaft connecting column is arranged in the middle of the gear forging ring, and a plurality of threaded limiting holes are distributed in an annular manner on the outer surface of the shaft connecting column.

[0008] Preferably, a hexagonal groove is provided in the middle of the shaft connecting column.

[0009] Preferably, a plurality of teeth are distributed in an annular shape on the outer surface of the gear forging ring.

[0010] Preferably, a forging circular hole is provided between two adjacent forging grooves. Beneficial Effects

[0011] The utility model provides a gear forging. Compared with the prior art, it has the following beneficial effects:

[0012] The utility model provides a connection limiting mechanism, and before the gear forging and the mechanical equipment transmission shaft are installed, the shaft connecting column is placed at the center of the gear ring, and the adjusting nuts in the grooves of the multiple forgings are respectively screwed with a wrench to retract the inner ends of the locking screws into the center position of the gear forging ring, until the inner ends of the multiple locking screws are completely screwed into the threaded limiting holes on the outer sides of the shaft connecting column. Under the locking action of the multiple locking screws, the shaft connecting column can be prevented from being separated from the inside of the gear forging ring. After that, the mechanical equipment transmission shaft can be inserted into the hexagonal groove of the shaft connecting column to achieve the installation of the gear forging and the shaft. If the hexagonal groove is worn and deformed due to the long-term use of the gear forging, the multiple adjusting nuts can be screwed in the opposite direction in the same way as mentioned above to separate the inner ends of the multiple locking screws from the shaft connecting column. At this time, the shaft connecting column can be removed and replaced and then reinstalled, without the need to replace the entire gear forging, thereby reducing maintenance costs.

[0013] 2. In the utility model, by setting a limit stop column, during the process of removing the shaft connecting column, as the user uses a wrench in reverse to twist the adjusting nut, the adjusting nut moves toward the outer end together with the locking screw. When the locking nut moves to a position that fits with the limit stop column, the inner end of the locking screw is completely disengaged from the threaded limit hole of the shaft connecting column. The limit stop column provides an obvious sign of disassembly completion, so that the operator can easily complete the disassembly work even under conditions of limited vision or narrow operating space, thereby improving disassembly efficiency.
