Abstract
Description
Technical Field
[0001] This utility model relates to the field of speed reducer technology, and in particular to a speed reducer heat dissipation device. Background Technology
[0002] As a commonly used piece of equipment in industrial production, the speed reducer is mainly installed between the power source and the working equipment to play a role in speed matching and torque transmission. However, during operation, the friction between the gears generates a lot of heat. Due to the high ambient temperature, the speed reducer relies solely on its own casing for heat dissipation, resulting in poor heat dissipation efficiency. This heat accumulation can cause the lubricating oil and seals to fail temporarily, and may even affect the transmission accuracy, leading to malfunctions and unsatisfactory performance.
[0003] Existing methods for cooling gearboxes generally fall into two categories. The first involves using external devices such as cooling plates and fans for heat dissipation. This method typically requires additional power, resulting in energy waste. The second method involves installing a cooling fan on the gearbox's input motor, with the motor driving the fan for cooling. However, this direct-blowing cooling method is ineffective. Utility Model Content
[0004] In order to solve the problems existing in the background art, the present invention provides a speed reducer heat dissipation device.
[0005] A speed reducer heat dissipation device includes a base plate, a speed reducer mounting base and two side plates at the upper end of the base plate, the speed reducer mounting base being detachably connected to the base plate by bolts, and a plurality of spaced strip-shaped mounting holes on the speed reducer mounting base; the two side plates are symmetrically arranged on both sides of the speed reducer mounting base, each side plate having uniformly distributed heat dissipation fins on its outer side and a heat-conducting contact plate on its inner side, the heat-conducting contact plate being connected to the side plate by a plurality of heat-conducting pipes.
[0006] Furthermore, the side plate and the base plate are connected by an angle steel bracket and an inverted U-shaped support frame; the angle steel bracket is fixedly connected to the side plate, and the bottom of the angle steel bracket is provided with a slider and an assembly hole, and the base plate is provided with a groove and a strip-shaped adjustment hole at the corresponding position. The slider and the groove slide in cooperation, and the assembly hole and the strip-shaped adjustment hole are positioned correspondingly. The angle steel bracket is fixed by fasteners that pass through the assembly hole and the strip-shaped adjustment hole; the two ends of the inverted U-shaped support frame are fixed to the upper end of the base plate, and the middle part spans the two side plates and is slidably connected to the side plates.
[0007] Furthermore, the heat dissipation fins are parallel plate-shaped structures, and horizontal air ducts with equal spacing are formed between adjacent heat dissipation fins.
[0008] Furthermore, the inverted U-shaped support frame has a horizontally extending top bracket in the middle, and the top bracket has a cooling fan mounting slot and an exhaust hole.

[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This utility model transfers the heat of the reducer to the side plate through a heat-conducting contact plate and multiple heat-conducting pipes. Evenly distributed heat dissipation fins are arranged on the outer side of the side plate, increasing the heat dissipation area and thus improving heat dissipation efficiency. This design eliminates the need for additional motor fans or coolant, reducing energy consumption and maintenance costs.

[0015] 3. The heat dissipation fins are parallel plate-shaped structures, with horizontal air ducts of equal spacing between adjacent fins.

[0016] 4. The inverted U-shaped support frame of this utility model has a horizontally extending top bracket in the middle, on which a cooling fan mounting slot and an array of exhaust holes are provided, which facilitates the installation of a cooling fan when needed, thereby enhancing the expandability of the device and the adjustability of its heat dissipation capacity.
[0017] 5.

[0020] Figure 2 This is a partially enlarged view of the present invention.
[0021] Figure 3 This is a schematic diagram of the structure of the side plate, heat dissipation fins, heat-conducting contact plate and heat-conducting pipe of this utility model. Detailed Implementation
[0022] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0023] like Figure 1-3 The speed reducer cooling device shown includes a base plate 10, a speed reducer mounting base 20, and two side plates 30. The speed reducer mounting base 20 and the two side plates 30 are located on the upper end of the base plate 10. The speed reducer mounting base 20 is detachably connected to the base plate 10 by bolts 21. The height of the speed reducer mounting base 20 can also be adjusted by the bolts 21, thereby adjusting the installation height of the speed reducer. In addition, a spring washer (not shown in the figure) is provided below the nut of the bolt 21. The spring washer is used to offset the vibration of the speed reducer and reduce the impact of vibration on the connection parts. Of course, rubber washer or other elastic material washer can also be used. The speed reducer mounting base 20 has multiple spaced strip-shaped mounting holes 23. The speed reducer is mounted on the speed reducer mounting base 20 by bolts or pins passing through the strip-shaped mounting holes 23. The multiple strip-shaped mounting holes 23 can accommodate more sizes and models of speed reducers. Two side plates 30 are symmetrically arranged on both sides of the reducer mounting base 20. Each side plate 30 has evenly distributed heat dissipation fins 31 on its outer side and a heat-conducting contact plate 32 on its inner side. The heat-conducting contact plate 32 is connected to the side plate 30 by multiple heat-conducting pipes 33.
[0024] After the speed reducer is installed, the heat-conducting contact plate 32 contacts the speed reducer housing. The heat generated by the speed reducer during operation is transferred through the heat-conducting contact plate 32 to the heat-conducting pipe 33, and then through the heat-conducting pipe 33 to the side plate 30, where it is dissipated by the heat dissipation fins 31.
[0025] By providing evenly distributed heat dissipation fins 31 on the outer side of the side plate 30, the heat dissipation area is significantly increased. When installing the reducer, ensure the thermally conductive contact plate 32 is in contact with the reducer housing, maximizing the contact area to facilitate heat transfer. To further increase the thermal conductivity and efficiency, apply silicone grease between the thermally conductive contact plate 32 and the reducer housing during installation. Furthermore, the thermally conductive contact plate 32 and heat pipe 33 are preferably made of copper, which is inexpensive and has high thermal conductivity. This device solves the problem of low heat dissipation efficiency in traditional reducer cooling systems. Moreover, it eliminates the need for additional motor fans or coolant, reducing energy consumption and maintenance costs, while avoiding the heat dissipation failure problems caused by fan or coolant system malfunctions in traditional cooling methods.
[0026] Furthermore, the top of the side panel 30 curves outward to form a handle 36, and the surface of the handle 36 is provided with anti-slip texture. This facilitates the operator's handling and movement of the entire heat dissipation device, improving the portability and ease of operation of the equipment. By providing an arc-shaped handle at the top of the side panel and providing anti-slip texture on the surface, it ensures that the operator can hold it firmly during handling, reducing accidental injuries caused by slipping.
[0027] In a preferred embodiment, the base plate 10 is made of Q235B steel plate, which has sufficient strength and rigidity to support the weight of the reducer and other components. The reducer mounting base 20 can be connected to the base plate 10 by welding or snap-fit connection, but bolt connection is more convenient for disassembly and maintenance. In addition, the strip-shaped mounting holes 23 on the reducer mounting base 20 are spaced approximately 15mm apart, with a total of 10 holes to accommodate the installation requirements of different models of reducers.
[0028] Furthermore, the top surface of the reducer mounting base 20 is provided with a temperature sensor recess 22. The temperature sensor recess 22 is located on the side of the reducer mounting base 20 that contacts the reducer, facilitating the installation of a temperature sensor for real-time monitoring of the reducer's operating temperature. The temperature sensor recess 22 adopts a rectangular structure to accommodate common temperature sensor dimensions. Alternatively, the temperature sensor can also be mounted on the reducer housing, but the recess design provides better protection for the sensor, preventing it from being affected by external interference and damage.
[0029] refer to Figure 1 and Figure 2In a preferred embodiment, the side plate 30 is connected to the base plate 10 via an angle steel bracket 40 and an inverted U-shaped support frame 50. The angle steel bracket 40 is fixedly connected to the side plate 30. The bottom of the angle steel bracket 40 is provided with a slider 42 and an assembly hole 41. The base plate 10 is provided with a corresponding position of a sliding groove 11 and a strip-shaped adjustment hole 12. The slider 42 slides in conjunction with the sliding groove 11. The assembly hole 41 and the strip-shaped adjustment hole 12 are positioned opposite each other. The angle steel bracket 40 is fixed by fasteners 43 that pass through the assembly hole 41 and the strip-shaped adjustment hole 12. The two ends of the inverted U-shaped support frame 50 are fixed to the upper end of the base plate 10, and the middle part spans the two side plates 30 and is slidably connected to the side plates 30. When installing the reducer, the distance between the two side plates 30 is adjusted to make the heat-conducting contact plate 32 contact the reducer housing. The flexible installation method of the angle steel bracket 40 and the inverted U-shaped support frame 50 not only improves the flexibility and adaptability of the installation, but also facilitates adjustment and maintenance when needed.
[0030] Furthermore, the inverted U-shaped support frame 50 also has a horizontally extending top bracket 51 in the middle, with a cooling fan mounting slot 52 and an exhaust hole 53 on the top bracket 51. The cooling fan mounting slot 52 allows the device to be equipped with or without a fan according to actual needs, improving the expandability and applicability of the equipment. The cooling fan is installed in an exhaust manner to quickly dissipate the heat accumulated between the side plate 30 and the bottom plate 10.
[0031] like Figure 3 As shown, in one specific embodiment, the heat dissipation fins 31 are parallel plate-shaped structures with a spacing of 10mm, totaling 20 fins. The heat dissipation fins 31 are made of aluminum alloy, and adjacent heat dissipation fins 31 form equally spaced horizontal air channels 31a. The extension direction of the horizontal air channels 31a is parallel to the axis of the input shaft of the reducer. The purpose of this arrangement is that when enhanced heat dissipation is required, a cooling fan is added to the shaft of the input motor of the reducer. After the fan operates, the airflow direction is exactly consistent with the horizontal air channel 31a, which can quickly remove heat from the vicinity of the horizontal air channel 31a, thereby improving heat dissipation efficiency. Alternatively, the heat dissipation fins 31 can also adopt a wavy or arc-shaped structure to increase the heat dissipation area and turbulent airflow.
[0032] This speed reducer cooling device effectively solves the problems of low heat dissipation efficiency and complex structure of traditional speed reducer cooling devices, improving the working reliability and service life of the speed reducer, and has significant practical value and market competitiveness. The above-described embodiments only illustrate preferred embodiments of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of this invention, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
