Description

Technical Field

[0001] This utility model belongs to the field of gear technology and relates to a split-type large gear. Background Technology

[0002] Gears are mechanical components with teeth on their rims that continuously mesh to transmit motion and power. In actual use, most gears are installed in enclosed spaces to prevent damage from foreign objects and to prevent impurities from adhering and causing accelerated wear, thus affecting their service life. However, gears rotate at high speeds for extended periods during use, and the enclosed space can easily lead to heat buildup, which is difficult to dissipate. Long-term heat buildup can cause corrosion of the gears, affecting their subsequent use. Furthermore, replacement costs are high when gears are damaged. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a large gear that has low replacement cost and heat dissipation function.

[0004] The objective of this utility model can be achieved through the following technical solution: A split-type large gear, comprising a gear body with a main shaft, characterized in that the gear body includes a gear ring with external teeth, a mounting bracket for mounting the main shaft, and a connecting unit for connecting the gear ring and the mounting bracket, the connecting unit including an upper connecting ring and a lower connecting ring, and a cavity between the upper connecting ring and the lower connecting ring, the connecting unit being provided with a heat dissipation unit located in the cavity, which is connected to the connecting unit, cooperates with the main shaft, and improves the heat dissipation effect.

[0005] In the aforementioned split-type large gear, the inner peripheral wall of the gear ring is provided with two radially inward protrusions, which are symmetrically arranged and are used to install corresponding upper and lower connecting rings. The outer peripheral wall of the mounting set is also provided with two protruding rings.

[0006] In the aforementioned split-type large gear, two bearings are provided between the assembly and the main shaft, which are sleeved on the main shaft and facilitate the rotation of the assembly. The two bearings are located at both ends of the assembly, and protective ring plates are provided on both ends of the assembly to protect the bearings.

[0007] In the aforementioned split-type large gear, both the upper and lower connecting rings are provided with several weight-reducing holes to improve heat dissipation and reduce weight.

[0008] In the aforementioned split-type large gear, the heat dissipation unit comprises a mounting shaft, meshing teeth, and an impeller. The two ends of the mounting shaft are respectively connected to an upper connecting ring and a lower connecting ring. The meshing teeth are sleeved on the mounting shaft and connected to it. The impeller is disposed on the meshing teeth and connected to them.

[0009] In the aforementioned split-type large gear, the assembly has a notch groove on the outer peripheral wall of the meshing teeth, and the main shaft has a meshing part located at the notch groove that is connected to and cooperates with the meshing teeth.

[0010] Compared with existing technologies, this split-type large gear improves the heat dissipation effect of the gear body by setting up a heat dissipation unit. Attached Figure Description

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1As shown, this split-type large gear includes a gear body 1 with a main shaft 2. The gear body 1 includes a hollow gear ring with external teeth, a mounting kit for mounting the main shaft 2, and a connecting unit for connecting the gear ring and the mounting kit. The connecting unit includes an upper connecting ring 3 and a lower connecting ring 4, and a cavity is left between the assembled upper connecting ring 3 and lower connecting ring 4. The inner ends of the upper connecting ring 3 and lower connecting ring 4 are connected to the outer ends of the mounting kit, and the outer ends of the upper connecting ring 3 and lower connecting ring 4 are connected to the gear ring. The connection unit is located within the cavity and is equipped with a heat dissipation unit that connects to and mates with the main shaft 2, improving heat dissipation. The inner circumferential wall of the gear ring has two radially inwardly protruding, symmetrically arranged, for mounting corresponding upper connecting ring 3 and lower connecting ring 4. The outer circumferential wall of the assembly also has two radially outwardly protruding, also for mounting corresponding upper connecting ring 3 and lower connecting ring 4. The protruding rings can be connected to the upper connecting ring 3 and lower connecting ring 4 via studs. Two bearings are provided between the main shaft 2 and the main shaft 2, which are sleeved on the main shaft 2 and facilitate the rotation of the assembly. The two bearings are located at both ends of the assembly. Protective ring plates 5 are provided on both ends of the assembly and are connected to them to protect the bearings. The heat dissipation unit consists of a mounting shaft 6, meshing teeth 7 and impeller 8. The two ends of the mounting shaft 6 are connected to the upper connecting ring 3 and the lower connecting ring 4, respectively. The meshing teeth 7 are sleeved on the mounting shaft 6 and are movably connected to it. The meshing teeth 7 can be connected to the mounting shaft 6 through the bearings. The impeller 8 is provided on the meshing teeth 7 and is connected to it. The impeller 8 can be a blade. The assembly has a notch groove on the outer peripheral wall of the meshing teeth 7. The main shaft 2 has a meshing part at the notch groove that is connected to it and cooperates with the meshing teeth 7. Through the meshing part, when the gear body 1 moves, since the main shaft 2 is fixed, the heat dissipation unit rotates with the gear body 1, and the meshing teeth 7 rotate synchronously by touching the meshing part, thereby improving airflow and achieving the purpose of heat dissipation.

[0015] As a preferred structure, both the upper connecting ring 3 and the lower connecting ring 4 are provided with several weight-reducing holes to improve heat dissipation and reduce weight.
