Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reducers, and more particularly to a reducer with heat dissipation fins. Background Art
[0002] A reducer is a relatively sophisticated machine designed to reduce speed and increase torque. It matches speed and transmits torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. Reducers can be divided into general-purpose and specialized categories based on their intended use. Each category has distinct design, manufacturing, and operational characteristics.
[0003] A reducer is an independent component consisting of a gear transmission, a worm transmission, and a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. The reducer will generate a certain temperature during operation. The temperature change varies according to climatic conditions, load capacity, the meshing conditions between internal gears, and internal mechanical damage. If the reducer operates at an abnormal temperature for a long time, it will cause abnormal wear between the gears inside the reducer.
[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0005] The purpose of the utility model is to provide a reducer with heat dissipation fins, which can achieve better heat dissipation effect and effectively improve the performance and service life of the reducer.
[0006] The utility model provides a reducer with heat dissipation fins, comprising a shell body and heat dissipation fins; the heat dissipation fins are annular, and a plurality of the heat dissipation fins are sleeved at intervals on the side of the shell body; two annular grooves are provided on the heat dissipation fins, and a plurality of heat dissipation notches perpendicular to the annular grooves are also provided on the heat dissipation fins.
[0007] By adopting the above technical solution, the multiple heat dissipation fins provided on the shell body increase the heat dissipation area of the shell body and improve the heat dissipation efficiency; at the same time, two annular grooves and multiple heat dissipation notches perpendicular to the annular grooves are provided on the heat dissipation fins, which further increase the heat dissipation area, improve the heat dissipation efficiency, and effectively improve the performance and service life of the reducer.
[0008] Furthermore, a receiving cavity is provided inside the shell body, and a low-temperature alloy is provided in the receiving cavity.
[0009] By adopting the above technical solution, when the reducer is working, the overall temperature of the reducer rises. When the temperature reaches the melting point of the low-temperature alloy, the low-temperature alloy melts from solid to liquid, and absorbs heat during melting, thereby taking away part of the heat inside the shell body; the low-temperature alloy melts and absorbs heat and its temperature remains unchanged, so a constant low-temperature area is formed in the area where the accommodating cavity is located, which is conducive to achieving better heat dissipation effect; when the reducer stops working, the overall temperature of the reducer decreases, and the low-temperature alloy in the accommodating cavity will change from liquid to solid; the reducer with heat dissipation fins of the utility model can achieve better heat dissipation effect, effectively improving the performance and service life of the reducer.
[0010] Furthermore, the melting point of the low-temperature alloy is between 46 degrees and 48 degrees.
[0011] By adopting the above technical solution, the melting point of the low-temperature alloy is between 46 degrees and 48 degrees, slightly lower than 50 degrees, which is conducive to efficient heat dissipation of the reducer and avoids a significant decrease in the efficiency of the reducer.
[0012] Furthermore, the distances between adjacent heat dissipation fins are the same.
[0013] Furthermore, 12 heat dissipation gaps are provided on the heat dissipation fins, and the distances between adjacent heat dissipation gaps are the same.
[0014] The reducer with heat dissipation fins of the utility model has multiple heat dissipation fins on the shell body to increase the heat dissipation area of the shell body and improve the heat dissipation efficiency; at the same time, two annular grooves and multiple heat dissipation notches perpendicular to the annular grooves are provided on the heat dissipation fins, which further increase the heat dissipation area, improve the heat dissipation efficiency, and effectively improve the performance and service life of the reducer.

[0026] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0027] The terms "first", "second", "third", "fourth", etc. in the description and claims of the present utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0028] Example 1
[0029] Figure 1 This is a schematic structural diagram of a reducer with heat dissipation fins provided in an embodiment of the present utility model. Figure 2 for Figure 1 Schematic diagram of the structure of the heat dissipation fins of the reducer with heat dissipation fins. Figure 1 、 Figure 2 The reducer with heat dissipation fins provided by an embodiment of the present invention includes a shell body 100 and heat dissipation fins 400; the heat dissipation fins 400 are annular, and a plurality of the heat dissipation fins 400 are arranged at intervals on the side of the shell body 100; two annular grooves 500 are provided on the heat dissipation fins 400, and a plurality of heat dissipation notches 600 perpendicular to the annular grooves 500 are also provided on the heat dissipation fins 400.
[0030] It should be noted that the multiple heat dissipation fins 400 provided on the shell body 100 increase the heat dissipation area of the shell body 100 and improve the heat dissipation efficiency; at the same time, the heat dissipation fins 400 are provided with two annular grooves 500 and multiple heat dissipation notches 600 perpendicular to the annular grooves 500, which further increase the heat dissipation area, improve the heat dissipation efficiency, and effectively improve the performance and service life of the reducer.
[0031] Figure 3 for Figure 1 Schematic diagram of the cross-sectional structure of the heat dissipation fins of the reducer with heat dissipation fins, Figure 4 for Figure 1 Another cross-sectional structural diagram of the heat dissipation fins of the reducer with heat dissipation fins. Figure 3 、 Figure 4 In the present invention, a receiving cavity 200 is provided inside the shell body 100 , and a low-temperature alloy 300 is provided in the receiving cavity 200 .
[0032] It should be noted that when the reducer is working, the overall temperature of the reducer rises. When the temperature reaches the melting point of the low-temperature alloy, the low-temperature alloy melts from solid to liquid, absorbing heat during melting, thereby taking away some of the heat inside the shell body. The low-temperature alloy melts and absorbs heat, and its temperature remains unchanged. Therefore, a constant low-temperature area is formed in the area where the accommodating cavity is located, which is conducive to achieving a better heat dissipation effect. When the reducer stops working, the overall temperature of the reducer drops, and the low-temperature alloy in the accommodating cavity changes from liquid to solid.
[0033] The reducer with heat dissipation fins of the utility model can achieve a better heat dissipation effect and effectively improve the performance and service life of the reducer.
[0034] Furthermore, the melting point of the low-temperature alloy 300 of the present invention is between 46 degrees and 48 degrees.
[0035] It should be noted that the melting point of the low-temperature alloy is between 46 degrees and 48 degrees, slightly lower than 50 degrees, which is conducive to efficient heat dissipation of the reducer and avoids a significant decrease in the efficiency of the reducer.
[0036] Furthermore, the distances between adjacent heat dissipation fins 400 are the same; 12 heat dissipation gaps 600 are provided on the heat dissipation fins 400, and the distances between adjacent heat dissipation gaps 600 are the same.
[0037] Based on the above description, it can be seen that the advantages of the present invention are:
[0038] 1. In the reducer with heat dissipation fins of the present invention, a plurality of heat dissipation fins 400 are provided on the shell body 100 to increase the heat dissipation area of the shell body 100 and improve the heat dissipation efficiency; at the same time, two annular grooves 500 and a plurality of heat dissipation notches 600 perpendicular to the annular grooves 500 are provided on the heat dissipation fins 400, which further increase the heat dissipation area, improve the heat dissipation efficiency, and effectively improve the performance and service life of the reducer.
[0039] 2. The reducer with heat dissipation fins of the present invention, when the reducer is working, the overall temperature of the reducer rises. When the temperature reaches the melting point of the low-temperature alloy, the low-temperature alloy melts from solid to liquid, and absorbs heat during melting, thereby taking away part of the heat inside the shell body; the low-temperature alloy melts and absorbs heat and its temperature remains unchanged, so a constant low-temperature area is formed in the area where the accommodating cavity is located, which is conducive to achieving better heat dissipation effect; when the reducer stops working, the overall temperature of the reducer decreases, and the low-temperature alloy in the accommodating cavity will change from liquid to solid; it can achieve better heat dissipation effect, and effectively improve the performance and service life of the reducer.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
