Description

Technical Field

[0001] This utility model relates to the field of main reducer technology, specifically to an upper housing of a main reducer. Background Technology

[0002] The main reducer is a key component in the transmission system that reduces speed and increases torque. When the engine is longitudinally mounted, it also changes the direction of torque rotation. It achieves speed reduction by using a gear with fewer teeth to drive a gear with more teeth; using bevel gear transmission can change the direction of torque rotation.

[0003] The main reducer generates heat during operation, and the longer it operates, the more heat is generated. Existing main reducer housings are typically enclosed and have poor heat dissipation performance, making it difficult to quickly dissipate heat from the inside of the housing. Over time, this leads to a reduction in the lifespan of the main reducer. Utility Model Content

[0004] The purpose of this utility model is to provide an upper housing for a main reducer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a main reducer upper housing, comprising a housing, characterized in that: a heat dissipation assembly is provided on the housing, the heat dissipation assembly comprising a plurality of heat-conducting fins, a plurality of heat dissipation plates, and a plurality of bolts, a plurality of mounting grooves A are provided through the upper and lower parts of the housing, the lower half of the heat-conducting fins are inserted into the mounting grooves A and then fixedly connected to the housing by bolts, the bottom wall of the heat dissipation plate is provided with mounting grooves B, the upper half of the heat-conducting fins are inserted into the mounting grooves B and then fixedly connected to the heat dissipation plate by bolts.

[0006] Preferably, a plurality of support plates are fixedly provided on the outer side of the housing, and an installation groove C communicating with the installation groove A is opened on the top wall of the support plate. The heat-conducting sheet is inserted into the installation groove A and the installation groove C and fixedly connected to the housing and the support plates.

[0007] Preferably, the heat-conducting sheet and the heat sink are respectively provided with through holes A and B, and the top wall of the support plate is provided with a positioning groove that communicates with the mounting groove C. After the heat sink is inserted into the positioning groove, the positions of through holes A and B coincide. The bolts are inserted into through holes A and B and are fixedly connected to the heat-conducting sheet and the heat sink.

[0008] Preferably, a positioning ring is fixedly provided on the inner side of the housing, and the lower half of the heat-conducting sheet is inserted into the mounting groove A and abuts against the positioning ring.

[0009] Preferably, the heat-conducting sheet and the support plate are respectively provided with through holes C and D. When the heat-conducting sheet is in contact with the positioning ring, the positions of through holes C and D coincide. The bolt is inserted into through holes C and D and fixedly connected to the heat-conducting sheet and the support plate.

[0010] Preferably, a plurality of heat sinks are fixedly disposed on the heat sink plate.

[0011] Preferably, the heat-conducting sheet is made of copper, and both the heat sink and the heat dissipation plate are made of aluminum.

[0012] The beneficial effects of this utility model are as follows: When using this utility model, the heat-conducting sheet is placed above the support plate, and the lower half of the heat-conducting sheet is inserted into mounting grooves A and C, so that the heat-conducting sheet abuts against the positioning ring, and the positions of through holes C and D coincide.

When the main reducer is working, the heat generated is transferred to the housing, the housing transfers the heat to the heat conduction plate, the heat conduction plate transfers the heat to the heat sink, and the heat is quickly dispersed through the heat sink and the heat sink. The heat sink and the heat sink then exchange heat with the heat conduction plate, which improves the heat dissipation efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-5 As shown, this utility model discloses an upper housing of a main reducer, including a housing 1. The housing 1 is provided with a heat dissipation assembly, which includes a plurality of heat-conducting plates 2, a plurality of heat dissipation plates 3, and a plurality of bolts 15. The housing 1 has a plurality of mounting slots A4 extending vertically. The lower half of the heat-conducting plate 2 is inserted into the mounting slot A4 and then fixedly connected to the housing 1 by bolts 15. The bottom wall of the heat dissipation plate 3 has a mounting slot B5. The upper half of the heat-conducting plate 2 is inserted into the mounting slot B5 and then fixedly connected to the heat dissipation plate 3 by bolts 15. In use, the heat-conducting plate 2 is placed above the support plate 6. The lower half of the heat-conducting plate 2 is inserted into the mounting groove A4 and mounting groove C7, so that the heat-conducting plate 2 abuts against the positioning ring 11, and the through hole C12 and through hole D13 are aligned. Bolt 15 is inserted into through hole C12 and through hole D13 to fix the heat-conducting plate 2 and the support plate 6, thus completing the installation of the heat-conducting plate 2 and the housing 1. The heat sink 3 is placed above the heat-conducting plate 2, and the upper half of the heat-conducting plate 2 is inserted into the mounting groove B5. At this time, the heat sink 3 is inserted into the positioning groove 10, so that the through hole A8 and through hole B9 are aligned. Bolt 15 is inserted into through hole A8 and through hole B9 to fix the heat-conducting plate 2 and the support plate 6. The hot plate 3 is fixedly connected, completing the installation of the heat sink 3 and the heat-conducting plate 2. When the main reducer is working, the heat generated is transferred to the housing 1, the housing 1 transfers the heat to the heat-conducting plate 2, the heat-conducting plate 2 transfers the heat to the heat sink 3, and the heat is quickly dispersed through the heat sink 3 and the heat sink 14. The heat sink 3 and the heat sink 14 then exchange heat with the heat-conducting plate 2, which improves the heat dissipation efficiency. In summary, this utility model has the beneficial effect of improving heat dissipation efficiency and solves the problem that the heat dissipation performance of the housing 1 of the existing main reducer is poor, making it difficult to quickly dissipate heat from the inside of the housing 1, which will lead to a reduction in the service life of the main reducer in the long run.

[0021] Preferably, a plurality of support plates 6 are fixedly disposed on the outer side of the housing 1. The top wall of each support plate 6 has a mounting groove C7 communicating with the mounting groove A4. The heat-conducting plate 2 is inserted into the mounting groove A4 and the mounting groove C7 and fixedly connected to the housing 1 and the support plates 6. The presence of several support plates 6 on the outer side of the housing 1 enhances its strength; the fixed connection of the heat-conducting plate 2 to the housing 1 and the support plates 6 through the mounting grooves A4 and C7 facilitates the assembly and disassembly of the heat-conducting plate 2.

[0022] Preferably, the heat-conducting plate 2 and the heat sink 3 are respectively provided with through holes A8 and B9, and the top wall of the support plate 6 is provided with a positioning groove 10 communicating with the mounting groove C7. After the heat sink 3 is inserted into the positioning groove 10, the positions of through holes A8 and B9 coincide. The bolt 15 is inserted into through holes A8 and B9 and fixedly connected to the heat-conducting plate 2 and the heat sink 3. Since the positioning groove 10 communicating with the mounting groove C7 is provided on the top wall of the support plate 6, after the heat sink 3 is inserted into the positioning groove 10, the positions of through holes A8 and B9 will coincide, which facilitates the positioning of the heat sink 3 and the installation of the bolt 15; since the bolt 15 is inserted into through holes A8 and B9 and fixedly connected to the heat-conducting plate 2 and the heat sink 3, it facilitates the disassembly and assembly of the heat sink 3.

[0023] Preferably, a positioning ring 11 is fixedly provided on the inner side of the housing 1, and the lower half of the heat-conducting plate 2 is inserted into the mounting groove A4 and abuts against the positioning ring 11. Since the lower half of the heat-conducting plate 2 is inserted into the mounting groove A4 and abuts against the positioning ring 11, it serves to prevent the heat sink 14 from falling into the housing 1.

[0024] Preferably, the heat-conducting plate 2 and the support plate 6 are respectively provided with through holes C12 and D13. When the heat-conducting plate 2 abuts against the positioning ring 11, the positions of through holes C12 and D13 coincide. The bolt 15 is inserted into through holes C12 and D13 to fix the heat-conducting plate 2 and the support plate 6. Since the positions of through holes C12 and D13 coincide when the heat-conducting plate 2 abuts against the positioning ring 11, it facilitates the positioning of the heat-conducting plate 2 and the installation of the bolt 15.

[0025] Preferably, a plurality of heat sinks 14 are fixedly disposed on the heat sink 3. The presence of these heat sinks 14 on the heat sink 3 increases the heat dissipation surface area and improves heat dissipation efficiency.

[0026] Preferably, the heat-conducting sheet 2 is made of copper, and the heat sink 3 and heat sink 14 are both made of aluminum. Because the heat-conducting sheet 2 is made of copper, it has extremely high thermal conductivity; and because the heat sink 3 and heat sink 14 are both made of aluminum, they have relatively high thermal conductivity and are lightweight.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
