[0003] In the prior art, sometimes the herringbone gear is relatively large in size. For the convenience of transportation, for such a relatively large herringbone gear, generally two helical gears with different bevel angles are produced during production, and the two helical gears are combined into a herringbone gear when reaching the place of use.
[0004] However, the combined herringbone gears in the prior art are usually fixed by fasteners, and during use, the herringbone gears may be separated due to the loosening of the fasteners, thereby causing certain production accidents. Content of the Utility Model
[0005] The purpose of the utility model is to provide a combined herringbone gear structure to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A combined herringbone gear structure includes a first helical gear and a second helical gear. The top and bottom cross-sections of the first helical gear and the second helical gear are circular rings. The bottoms of the first helical gear and the second helical gear are respectively provided with a first bottom plate and a second bottom plate. A plurality of first missing openings are opened inside the top of the first helical gear. The bottoms of the plurality of first missing openings are on the same horizontal plane as the top of the first bottom plate. A plurality of second missing openings are opened inside the top of the second helical gear. The bottoms of the plurality of second missing openings are on the same horizontal plane as the top of the second bottom plate. The first missing openings and the second missing openings correspond one by one. A fixing opening is opened at the center of the bottom of the first missing opening. A limiting opening is opened at the center of the bottom of the second missing opening. The fixing opening and the limiting opening are connected by a fixing bolt. A first through hole is opened at the center of the top and bottom of the first bottom plate. A second through hole is opened at the center of the top and bottom of the second bottom plate. The first through hole and the second through hole are connected by a fixing sleeve inside.
[0008] Preferably, a first fixing ring is arranged at the top of the fixing sleeve, and a magnetic connection is carried out between the bottom of the first fixing ring and the first bottom plate.
[0009] Preferably, a second fixing ring is arranged at the bottom of the fixing sleeve, and a magnetic connection is carried out between the bottom of the second fixing ring and the second bottom plate.
[0010] Preferably, a plurality of fixing columns are provided at the top of the second bottom plate and at the bottom of the second helical gear. A plurality of jacks are provided at the bottom of the first bottom plate and at the bottom of the first helical gear. The fixing columns are snap-connected in the jacks.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the combined herringbone gear structure of the present utility model, on the basis that the existing first helical gear and the second helical gear are connected by fixing bolts, a plurality of fixing columns are provided at the bottom of the second bottom plate, and a plurality of jacks are provided at the bottom of the first bottom plate.

[0019] Please refer to Figure 1-2 , the present utility model provides a technical solution:
[0020] A combined herringbone gear structure includes a first helical gear 1 and a second helical gear 2. The top and bottom cross-sections of the first helical gear 1 and the second helical gear 2 are circular rings. The bottoms of the first helical gear 1 and the second helical gear 2 are respectively provided with a first bottom plate 3 and a second bottom plate 16. A plurality of first missing ports 6 are opened inside the top of the first helical gear 1. The bottoms of the plurality of first missing ports 6 are at the same horizontal plane as the top of the first bottom plate 3. A plurality of second missing ports 11 are opened inside the top of the second helical gear 2. The bottoms of the plurality of second missing ports 11 are at the same horizontal plane as the top of the second bottom plate 16. The first missing ports 6 and the second missing ports 11 correspond one by one. A fixing port 8 is opened at the center of the bottom of the first missing port 6. A limiting port 15 is opened at the center of the bottom of the second missing port 11. The fixing port 8 and the limiting port 15 are connected by a fixing bolt 7. First through holes 10 are opened at the centers of the top and bottom of the first bottom plate 3. Second through holes 13 are opened at the centers of the top and bottom of the second bottom plate 16. The inside of the first through holes 10 and the second through holes 13 are connected by a fixing sleeve 5.
[0021] Furthermore, a first fixing ring 4 is provided at the top of the fixing sleeve 5. A magnetic connection is made between the bottom of the first fixing ring 4 and the first bottom plate 3.
[0022] Furthermore, a second fixing ring 12 is provided at the bottom of the fixing sleeve 5. A magnetic connection is made between the bottom of the second fixing ring 12 and the second bottom plate 16.
[0023] Specifically, during installation, the top of the fixing sleeve 5 is integrally connected to the first fixing ring 4. After the first helical gear 1 and the second helical gear 2 are installed, the combination of the fixing sleeve 5 and the first fixing ring 4 is inserted into the first through hole 10 and the second through hole 13. During the installation process, the first fixing ring 4 will be adsorbed on the top of the first base plate 3. After the first fixing ring 4 is adsorbed, a part of the bottom of the fixing sleeve 5 will extend. Then, the central notch of the second fixing ring 12 is sleeved on the outer surface of the fixing sleeve 5. Since the material of the second base plate 16 is the same as that of the first base plate 3, the second fixing ring 16 will be adsorbed at the second base plate 16.
[0024] Furthermore, several fixing columns 14 are provided at the top of the second base plate 16 and at the bottom of the second helical gear 2. Several jacks 9 are opened at the bottom of the first base plate 3 and at the bottom of the first helical gear 1. The fixing columns 14 are connected to the jacks 9 in a snap-fit manner.
[0025] Specifically, when the first helical gear 1 is placed above the second helical gear 2, the jack 9 at the bottom of the first helical gear 1 needs to be aligned with the fixing column 14, so as to better fix the first helical gear 1 and the second helical gear 2.
[0026] In a combined herringbone gear structure of the present utility model, on the basis that the existing first helical gear 1 and the second helical gear 2 are connected by fixing bolts 7, several fixing columns 14 are provided at the bottom of the second base plate 16, and several jacks 9 are opened at the bottom of the first base plate 3. The fixing columns 14 are connected to the jacks 9 in a snap-fit manner. In addition, a first through hole 10 and a second through hole 13 are respectively opened through the centers of the first base plate 3 and the second base plate 16. The first through hole 10 and the second through hole 13 are connected by a fixing sleeve 5. A first fixing ring 4 and a second fixing ring 12 are respectively provided at the top and bottom of the fixing sleeve 5. The first fixing ring 4 and the second fixing ring 12 are respectively magnetically connected to the first base plate 3 and the second base plate 16. Through the above design, when the fixing bolts 7 are loose, the first helical gear 1 and the second helical gear 2 will still be connected through the cooperation of the fixing sleeve 5, the first fixing ring 4, and the second fixing ring 12, and the first helical gear 1 and the second helical gear 2 will not be separated due to the loosening of the fixing bolts 7, thus avoiding production accidents.
[0027] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
