Description

Technical Field

[0001] This utility model relates to the field of transmission gear technology, specifically a gear with a splicing structure. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. Gears have been used in transmission for a long time. In the late 19th century, with the emergence of the generating gear cutting method and specialized machine tools and cutting tools using this principle, the smoothness of gear operation became increasingly important as production developed.

[0003] Currently, most gears on the market are one-piece structures, which means that when the gear wears out, the entire gear needs to be replaced, resulting in serious waste of resources. At the same time, one-piece gears are very difficult to install and disassemble in a confined space, and are prone to damage to the gear teeth, resulting in waste. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gear with a splicing structure, which has the advantages of high practicality and convenient installation, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a gear with a splicing structure, including a first gear inner disk mechanism, a second gear inner disk mechanism is snapped onto one side of the first gear inner disk mechanism, two No. 3 fixing bolts are threadedly fixed to the upper end face of the first gear inner disk mechanism, two gear outer disk mechanisms are snapped onto the outer sides of the first gear inner disk mechanism and the second gear inner disk mechanism, two No. 1 fixing bolts are threadedly connected to the upper end face of each of the two gear outer disk mechanisms, and two No. 2 fixing bolts are threadedly connected to the lower end face of each of the two gear outer disk mechanisms.

[0006] As a preferred technical solution of this utility model, the gear outer disk mechanism includes a gear outer disk body, a plurality of gear teeth are fixedly installed on the outer side of the gear outer disk body, two No. 2 screw holes are opened on the upper end face of the gear outer disk body, and a No. 3 screw hole is opened on one side of the upper end face of the gear outer disk body.

[0007] As a preferred technical solution of this utility model, a No. 1 snap-fit ​​block is fixedly installed on one side of the gear outer disk body, a No. 1 screw hole is opened on the upper end face of the No. 1 snap-fit ​​block, a No. 2 snap-fit ​​groove is opened on the other side of the gear outer disk body, and two No. 1 snap-fit ​​grooves are opened on the inner wall of the gear outer disk body.

[0008] As a preferred technical solution of this utility model, the first gear inner disk mechanism includes a first gear inner disk body, and two second snap-fit ​​blocks are fixedly installed on both sides of the first gear inner disk body. The upper end face of the two second snap-fit ​​blocks is provided with a fourth screw hole.

[0009] As a preferred technical solution of this utility model, two No. 3 snap-fit ​​blocks are fixedly installed on the outer side of the main body of the No. 1 gear inner disk, and No. 5 screw holes are opened on the upper end face of the two No. 3 snap-fit ​​blocks.

[0010] As a preferred technical solution of this utility model, the second gear inner disk mechanism includes a second gear inner disk body, and the second gear inner disk body has a third snap-fit ​​groove on both sides, and two sixth screw holes are opened on the upper end face of the second gear inner disk body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This type of gear with a splicing structure divides an integrated gear into an outer gear disc mechanism, a first inner gear disc mechanism, and a second inner gear disc mechanism. The various mechanisms are connected by snap-fit ​​blocks and reinforced with fixing bolts. When the gear teeth are severely worn, only the bolts need to be removed and the corresponding outer gear disc mechanism needs to be replaced, without replacing the entire gear, thereby reducing the waste of resources.

[0014] 2. This type of gear with a splicing structure divides the inner disk of the gear into a first inner disk mechanism and a second inner disk mechanism. When installing the gear in a narrow space, the first inner disk mechanism and the second inner disk mechanism can be interlocked and fixed from both sides of the mounting shaft, which can quickly complete the gear installation and protect the gear teeth, preventing damage to the teeth during the installation process.

[0023] In a preferred embodiment, the integrated gear is divided into a first inner gear mechanism 2, a second inner gear mechanism 4, and a gear outer mechanism 1, which can be interlocked with each other. Then, the first inner gear mechanism 2 and the second inner gear mechanism 4 are threadedly fixed by a third fixing bolt 6, the two gear outer mechanisms 1 are threadedly fixed by a second fixing bolt 5, and the first inner gear mechanism 2, the second inner gear mechanism 4, and the gear outer mechanism 1 are threadedly fixed by a first fixing bolt 3. This increases the overall strength of the spliced ​​gear and ensures the overall stability of the spliced ​​gear.

[0024] The gear outer disk mechanism 1 includes a gear outer disk body 101. Multiple gear teeth 104 are fixedly installed on the outer side of the gear outer disk body 101. Two No. 2 screw holes 105 are opened on the upper end face of the gear outer disk body 101. A No. 3 screw hole 107 is opened on the upper end face of one side of the gear outer disk body 101. A No. 1 snap-fit ​​block 102 is fixedly installed on one side of the gear outer disk body 101. A No. 1 screw hole 103 is opened on the upper end face of the No. 1 snap-fit ​​block 102. A No. 2 snap-fit ​​groove 108 is opened on the other side of the gear outer disk body 101. Two No. 1 snap-fit ​​grooves 106 are opened on the inner wall of the gear outer disk body 101.

[0025] In a preferred embodiment, the first snap-fit ​​block 102 and the second snap-fit ​​groove 108 on the outer gear disc mechanism 1 can be snapped together and fixed. Then, the two outer gear disc mechanisms 1 are threadedly fixed by passing the second fixing bolt 5 through the third screw hole 107 and the first screw hole 103. The first snap-fit ​​groove 106 opened on the inner wall of the outer gear disc body 101 is used to snap together with the first inner gear disc mechanism 2 and the second inner gear disc mechanism 4.

[0026] The first gear inner disk mechanism 2 includes a first gear inner disk body 201. Two second locking blocks 202 are fixedly installed on both sides of the first gear inner disk body 201.

Two third locking blocks 204 are fixedly installed on the outer side of the first gear inner disk body 201. The upper end face of the two third locking blocks 204 is provided with a fifth screw hole 205.

[0027] In a preferred embodiment, the second snap-fit ​​blocks 202 on both sides of the inner disk body 201 of the first gear are used to snap-fit ​​with the inner disk mechanism 4 of the second gear, and the third snap-fit ​​block 204 on the outer side of the inner disk body 201 of the first gear is used to snap-fit ​​with the outer disk mechanism 1 of the gear, thereby splicing together the entire gear.

[0029] In a preferred embodiment, after the second snap-fit ​​block 202 is snapped into the third snap-fit ​​groove 402, it is fixed by the third fixing bolt 6 passing through the sixth screw hole 403 and the fourth screw hole 203, thereby increasing the overall stability of the spliced ​​gear. The fourth snap-fit ​​block 404 is used to snap-fit ​​with the gear outer disk mechanism 1, thereby splicing into a complete gear.

[0030] The working principle is that the integrated gear is divided into an outer gear plate mechanism 1, a first inner gear plate mechanism 2, and a second inner gear plate mechanism 4. The various mechanisms are connected by snap-fit ​​blocks and reinforced with fixing bolts. When the gear teeth 104 are severely worn, only the bolts need to be removed and the corresponding outer gear plate mechanism 1 needs to be replaced. There is no need to replace the entire gear, which can reduce the waste of resources.

[0031] Secondly, by dividing the inner gear disk into a first inner gear disk mechanism 2 and a second inner gear disk mechanism 4, when installing the gear in a narrow space, the first inner gear disk mechanism 2 and the second inner gear disk mechanism 4 can be interlocked and fixed from both sides of the mounting shaft, which can quickly complete the gear installation and also protect the gear teeth 104 and prevent the teeth 104 from being damaged during the installation process.
