[0027] like Figures 1 to 5As shown, a speed reducer cooling cover includes a cover body 3 for mounting on a speed reducer housing 1. The cover body 3 has a mating surface on one side facing the gear set 2 inside the speed reducer housing 1, which mates with the outer side of the gear set 2. The mating surface is open, and a safety distance is provided between the mating surface and the gear set 2. A heat dissipation component is provided on the cover body 3 that extends into the speed reducer housing 1. The heat dissipation component includes a plurality of horizontally arranged first heat dissipation fins 5, which are vertically arranged at equal intervals. The end of the first heat dissipation fins 5 closest to the gear set 2 is located on the mating surface.
[0028] Multiple first heat sinks 5 are provided on the cover plate body 3, extending into the reducer housing 1, so that the first heat sinks 5 are close to the gear set 2, allowing the first heat sinks 5 to carry away more heat and enhance the heat exchange and cooling effect. The arrangement of multiple first heat sinks 5 increases the heat dissipation area inside the reducer housing 1, resulting in a better heat exchange and cooling effect.
[0029] A horizontally arranged second heat sink 6 is provided between two adjacent first heat sinks 5. The distance between the end of the second heat sink 6 closest to the gear set 2 and the outer side of the gear set 2 is greater than the safety clearance. The addition of the second heat sink 6 allows it to carry away more heat, enhancing the heat exchange and cooling effect. The arrangement of the second heat sink 6 increases the heat dissipation area inside the reducer housing 1, resulting in better heat exchange and cooling. The space between the second heat sink 6 and the outer side of the gear set 2 facilitates air circulation, further improving the heat exchange and cooling effect.
[0030] Both the first heat sink 5 and the second heat sink 6 are aluminum alloy heat sink fins, which facilitates improved heat dissipation performance.
[0031] The endpoints of the mating surfaces are set at the same shortest distance as the sidewall of the gear set 2.
[0032] The outer side of the cover plate body 3 is provided with a plurality of vertically arranged vertical air guide plates 4. The plurality of vertical air guide plates 4 are arranged at equal intervals. The vertical air guide plates 4 are arc-shaped plates, which also increase the heat dissipation area. The heat inside the reducer housing 1 can also be dissipated more from the outer side of the cover plate body 3 through the vertical air guide plates 4.
[0033] The angle between the vertical air guide plate 4 and the outer side of the cover plate body 3 is less than 90 degrees, which helps to reduce the entry of foreign objects from the reducer housing 1 into the reducer housing 1.
[0034] The cover plate body 3 is detachably installed on the reducer housing 1, so that when the cover plate body 3 needs to be replaced, it is convenient to remove the cover plate body 3 from the reducer housing 1.
[0035] like Figure 6 and Figure 7 As shown, cooling pipes 7 are provided on both sides of the cover plate body 3. The upper end of each cooling pipe 7 is connected to a liquid inlet, and the lower end of each cooling pipe 7 is connected to a liquid outlet via a horn-shaped guide pipe. Multiple first guide plates 8 are arranged at equal vertical intervals on one side of each cooling pipe 7, and multiple second guide plates 9 are arranged at equal vertical intervals on the other side of each cooling pipe 7. Both the first and second guide plates 8 and 9 are inclined and staggered vertically. The lower end of each first guide plate 8... The first guide plate 8 is located above the middle of the second guide plate 9 below it, and the lower end of the second guide plate 9 is located above the middle of the first guide plate 8 below it. The upper surfaces of the first guide plate 8 and the second guide plate 9 are both provided with inclined water-blocking protrusions. Coolant or cooling water enters the cooling pipe 7 through the inlet. The first guide plate 8, the second guide plate 9 and the water-blocking protrusions facilitate the extension of the flow time of the coolant or cooling water, so that the coolant or cooling water can stay in the cooling pipe 7 for a longer time and finally be discharged from the outlet, taking away more heat and enhancing the heat dissipation and cooling effect.
