Description

Technical Field

[0001] The utility model belongs to the technical field of gears, and in particular relates to an assembled triple gear. Background Art

[0002] A triple gear is a gear structure commonly used in automobile drives and is a type of gear. For example, the existing triple gear is shown in a triple gear for an inter-axle differential in China's utility model patent publication number CN216009457U. Its effect is to reduce the axial size of the triple gear and lightweight the triple gear by designing the meshing teeth as a whole within the cylindrical space wrapped by the cylindrical teeth.

[0003] However, in actual use, since the triple teeth and the mating surface are in a vibration state during the driving process, it is easy to cause mechanical wear. Therefore, after long-term use, the tooth surface of the triple teeth is easily damaged, resulting in meshing failure. Moreover, when replacing, the entire triple teeth need to be dismantled and replaced, which is quite inconvenient. Therefore, we specially designed an assembled triple teeth. Utility Model Content

[0005] In view of this, the present invention provides an assembled triple gear, comprising:

[0006] A main body, wherein an axial hole is formed on the main body, side teeth are formed on the side wall surface of the main body, and a tooth surface is formed on the end surface of the other side of the main body;

[0007] The movable chainring is detachably arranged on the end surface of the main body away from the tooth surface, and the movable chainring is the output end.

[0008] In the above technical solution, further, the movable crankset includes:

[0009] A disc body, wherein a through hole is formed on the disc body, and a tooth-shaped protrusion is formed on an end surface of one side of the disc body;

[0010] Bolts are arranged on the disc body, a plurality of first bolt holes are correspondingly formed on the disc body, and a second bolt hole is correspondingly formed on the end surface of the main body.

[0011] In the above technical solution, further comprising:

[0012] Hexagonal port, the hexagonal port is formed on the end surface where the main body and the disc are connected, and the disc corresponds to the hexagonal groove;

[0013] The first bolt holes are distributed around the hexagonal groove, and the second bolt holes are distributed outside the hexagonal port.

[0014] In the above technical solution, further comprising:

[0015] The liner is set in the hexagonal groove.

[0016] In the above technical solution, further comprising:

[0017] The bushing is arranged in the shaft hole.

[0031] Example 1:

[0032] This embodiment provides an assembled triple tooth, comprising:

[0033] The main body 1 has an axial hole 2 formed thereon, side teeth 3 formed on the side wall surface of the main body 1, and a tooth surface 4 formed on the end surface of the other side of the main body 1;

[0034] The movable chainring 5 is detachably arranged on the end surface of the main body 1 away from the tooth surface 4, and the movable chainring 5 is the output end.

[0035] As can be seen from this embodiment, an assembled triple toothed gear comprises a main body 1 and a movable toothed gear plate 5;

[0036] An axial hole 2 is formed on the main body 1, and side teeth 3 are formed on the side wall surface of the main body 1. When in use, the side teeth 3 are connected to the driving component. A tooth surface 4 is formed on the end surface of one end of the main body 1. When in use, the tooth surface 4 is driven by the side teeth 3 to rotate and at the same time connects to the driving component to play a driving role. A movable chainring 5 is detachably mounted on the end surface of the other end of the main body 1. The movable chainring 5 is the output end for connecting to an external working component.

[0037] By setting a detachable movable chainring 5 as the output end, in the event of damage or tooth meshing failure during use, maintenance can be carried out by replacing the movable chainring 5, thereby reducing maintenance costs. At the same time, the maintenance efficiency can be improved by removing the chainring separately without disassembling the entire chainring. By setting the side teeth 3 and the movable chainring 5, the triple tooth can be assembled with more gear parts, thereby saving usage space.

[0038] Example 2:

[0039] This embodiment provides an assembled triple tooth, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The movable chainring 5 includes:

[0041] A disc body 51 is formed with a through hole, and a tooth-shaped protrusion 511 is formed on one end surface of the disc body 51;

[0042] Bolts 52 are provided on the disc body 51 . The disc body 51 is correspondingly formed with a plurality of first bolt holes 6 , and the end surface of the main body 1 is correspondingly formed with second bolt holes 7 .

[0043] As can be seen from this embodiment, the movable crankset 5 includes a crankset body 51 and a bolt 52;

[0044] A through hole is provided on the disk body 51, and one end face of the disk body 51 is connected to the main body 1, and a tooth-shaped protrusion 511 is formed on the end face of the other side. A first bolt hole 6 is provided in the gap between the tooth-shaped protrusions 511, and the pin holes are arranged in an equidistant array circumferentially on the disk body 51, and the main body 1 has a second bolt hole 7 corresponding to the first bolt hole 6. The disk body 51 is placed on the main body 1, and after the first bolt hole 6 and the second bolt hole 7 are aligned, it is fixed by the bolt 52. The connection of the bolt 52 is firm, and the first bolt hole 6 and the second bolt hole 7 cause little damage to the overall structure of the disk body 51 and the main body 1, and are convenient for disassembly.

[0045] Example 3:

[0046] This embodiment provides an assembled triple tooth, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] Hexagonal port 8, the hexagonal port 8 is formed on the end surface where the main body 1 is connected to the disc 51, and the disc 51 corresponds to the hexagonal groove 9;

[0048] The first bolt holes 6 are distributed around the hexagonal groove 9 , and the second bolt holes 7 are distributed outside the hexagonal port 8 .

[0049] In this embodiment, it can be seen that the hexagonal port 8 is formed on the end face of the main body 1 connected to the disc body 51, and a second bolt hole 7 is formed on the end face of the main body 1 outside the hexagonal port 8. The disc body 51 is formed with a hexagonal groove 9 corresponding to the hexagonal port 8, and a second bolt hole 7 is formed on the disc body 51 outside the hexagonal groove 9.

[0050] When in use, the hexagonal slot 9 and the hexagonal port 8 are matched together. During the matching process, the corner structures of the hexagonal slot 9 and the hexagonal port 8 can play a positioning role, so that the first bolt hole 6 and the second bolt hole 7 can better correspond to each other, which makes it convenient to use bolts 52 for reinforcement. At the same time, the mutual support of the corner structures can increase the force area between the disk body 51 and the main body 1, so that the torque transmitted by the main body 1 is more transmitted through the corner structure, thereby reducing the stress on the bolt 52 and improving the structural strength.
