For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a gearbox housing casting with good heat dissipation. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7 .

[0032] To address the problems of existing technologies that rely on a series of moving parts to achieve heat dissipation and cooling, resulting in complex structures, high overall processing and assembly costs, and cumbersome disassembly and assembly operations due to bolt connections between housings, this solution proposes a high-heat-dissipation reducer housing casting. This casting comprises a lower housing 1, an upper housing 2 that engages with the upper end of the lower housing 1, and a reduction gear set 3 installed in the middle of the lower housing 1. Multiple heat dissipation components are located inside the lower housing 1, consisting of fan blades 4 mounted on the drive shaft of the reduction gear set 3, heat dissipation copper plates 5 embedded in the inner sides of the left and right ends of the lower housing 1, and heat dissipation fins 6 located on the outer side of the heat dissipation copper plates 5. A fixing mechanism is located at the corner of the upper end of the lower housing 1, and this fixing mechanism enables the upper housing 2 to form a disassembly structure at the upper end of the lower housing 1.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during operation, the reduction gear set 3 inside the lower housing 1 drives the fan blade 4 to rotate inside the lower housing 1 via the drive shaft. This allows the heat inside the lower housing 1 to be quickly dissipated outward through the through hole 7, achieving a good heat dissipation effect. Furthermore, with the combination of the heat dissipation fins 6 and the through hole 7, the heat dissipation fins 6 are embedded inside the lower housing 1, while the through hole 7 extends outward from the lower housing 1. Through the heat dissipation fins 6 and the through hole 7, heat is conducted from the heat dissipation fins 6 to the through hole 7 and then dissipated outward, further improving the actual heat dissipation effect. Moreover, the overall structural design is very simple, the production cost is low, and it is suitable for widespread use. In addition, the dustproof net 8 can prevent external dust from entering the lower housing 1 through the through hole 7 during heat dissipation, achieving a good dustproof effect. When there is a lot of dust on the dustproof net 8, the dustproof net 8 can be disassembled, cleaned, and replaced simply by loosening the fastening bolt 9.

[0034] When maintenance is required on the components inside the lower housing 1, such as Figure 6 and Figure 7As shown, the fixing mechanism includes a protrusion 10, a fixing plate 11, a fixing groove 12, an auxiliary block 13, a movable plate 14, a connecting rod 15, and a connecting cap 16. By rotating the connecting cap 16 on the outer surface of the threaded connecting rod 15, the connecting cap 16 loosens the limit between the connecting rod 15 and the movable plate 14. Then, the movable plate 14, which is hinged to the middle of the auxiliary block 13, is flipped over. At the same time, the auxiliary block 13 is fixed to the side of the upper end of the lower housing 1. The movable plate 14 rotates with the auxiliary block 13. At this time, the movable plate 14 is limited between the protrusion 10 and the upper housing 2, thereby loosening the limit between the upper housing 2 and the lower housing 1. Then, the upper housing 2 is pulled upward to disassemble the upper housing 2, which facilitates the disassembly, maintenance, and upkeep of the components inside the lower housing 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
