Description
Technical Field
[0001] This invention relates to the field of bearing housing structure technology, specifically to an optimized heat dissipation structure for an outer spherical bearing housing. Background Technology
[0002] A bearing housing is a large or extra-large bearing housing with a special structure that can accept comprehensive loads. It is characterized by its compact structure, sensitive rotation, and convenient installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is commonly referred to as the bearing housing. Spherical roller bearing housings are important mechanical components widely used in various industrial equipment, especially in heavy-duty, long-term continuous operation environments where the bearing's operating temperature rises significantly. Traditional spherical roller bearing housings typically rely on the thermal conductivity of the material and the designed heat dissipation channels for heat dissipation.
[0003] The existing technology has the following defects or problems: Existing spherical bearing housing structures are mostly integrated, resulting in poor air circulation. They rely on external structures for heat dissipation and lack internal circulation cooling structures. Furthermore, the outer wall does not have additional heat-conducting structures, making it impossible to effectively dissipate internal temperatures.
[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an optimized heat dissipation structure for spherical bearing housings, solving the current problems.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an optimized heat dissipation structure for an outer spherical bearing housing, comprising: The mounting base has four mounting ends at its top, each mounting end being a mounting nut and a threaded connection of a screw. The mounting base has screw holes at the four ends corresponding to the mounting ends. The mounting ends are used to achieve a stable connection between the mounting base and external equipment. A bearing seat is provided on the top of the mounting base, and a bearing seat body is provided on the top end face of the bearing seat for stable installation of the bearing; The mounting base has a mounting groove in the middle of the top end face, the bearing base has a slot at the bottom, and a circulation box is provided between the mounting groove and the slot. The bearing housing body has an installation hole inside, and an outer spherical bearing is installed inside the installation hole; A heat-conducting component is disposed on both sides of the top end face of the bearing housing body to achieve effective heat conduction.
[0007] In some embodiments, the bearing housing body has fixed ends fixedly connected to both sides of its bottom, and the bearing seat has a fixed groove at the corresponding position. The size of the fixed end is the same as the size of the fixed groove, and the connection between the two is achieved by welding. A heat insulation cavity is provided between the bearing housing body and the bearing seat through two sets of fixed ends.
[0008] In some embodiments, a circulating fan is fixedly installed inside the circulation box, and the output end and return end of the circulating fan are respectively fixedly connected to an air guide pipe and a return air pipe; The bearing seat has through holes on both sides of the bottom end face, and the air guide pipe and return air pipe extend into the bearing seat body through the through holes; The air inlet of the circulating fan is connected to an air inlet pipe, and a hole is provided on the rear side of the circulating box to accommodate the extension of the air inlet pipe.
[0009] In some embodiments, the bearing housing body has an air hole inside, which is specifically composed of an air inlet and an air outlet, and is connected to an air duct and a return air duct respectively. The two are used to cooperate with the internal fan mechanism of the circulation box to form a circulation air duct.
[0010] In some embodiments, limit plates are detachably mounted on both the front and rear sides of the mounting holes inside the bearing housing body via bolts; Each set of limiting plates is composed of four sets of arc-shaped panels arranged in a ring array. The outer spherical bearing is disposed between two sets of limiting plates, and a flow cavity is provided at intervals between the mounting hole walls to maintain the flow of cooling air.
[0011] In some embodiments, heat-conducting grooves are provided on both sides of the top end face of the bearing housing body, and heat-conducting components are fixedly connected inside the two sets of heat-conducting grooves. The bottom of the heat-conducting groove is embedded with a heat-conducting copper sheet, and a heat dissipation hole is opened through the bottom end face. Several sets of heat dissipation holes are provided.
[0012] In some embodiments, the heat-conducting component specifically comprises a heat-conducting plate and heat dissipation fins, both made of copper. The heat-conducting plate is fixedly installed inside the heat-conducting groove, and the two are sized to fit together tightly. Heat dissipation fins are fixedly installed on the top of the heat-conducting plate, and the heat dissipation fins are arranged in several groups, specifically in an inverted L-shape, to increase the heat conduction area. In some embodiments, the spherical bearing includes; Bearing outer sleeve, wherein the bearing outer sleeve is disposed inside the mounting hole; The bearing inner ring is movably installed inside the bearing outer ring, and the two are slidably connected. An eccentric sleeve is fixedly connected to the front end face of the bearing inner ring for connecting the shaft structure to achieve transmission. Fixing bolts are provided on all four sides of the outer side of the eccentric sleeve.
[0013] Compared with the prior art, the present invention provides an optimized heat dissipation structure for an outer spherical bearing housing, which has the following beneficial effects: 1. The optimized heat dissipation structure of the outer spherical bearing housing is provided by setting up a mounting base, a bearing base and a bearing housing body, which are connected in a split structure. At the same time, a heat insulation cavity is provided between the bottom of the bearing housing body and the bearing base to improve air circulation. Compared with the existing bearing housing structure, the optimized heat dissipation structure has a better heat conduction effect. 2. This optimized heat dissipation structure for an outer spherical bearing housing comprises a circulation box, an air duct, a return air duct, a bearing housing body, and heat conduction components. The circulation box contains a circulating fan that draws air through the air duct into the air inlet of the bearing housing body, ensuring that circulating air can enter the mounting hole and blow onto the internally mounted outer spherical bearing. This carries heat from the bearing surface into the air outlet, and the air is returned through the return air duct, thus forming a circulating cooling structure. This allows the heat inside the bearing housing body to be circulated out, improving the heat dissipation effect of the structure. 3. This optimized heat dissipation structure for an outer spherical bearing housing, by setting up heat conduction components, allows heat to rise during the operation of the circulating cooling structure. Heat can then enter the heat conduction groove through the heat dissipation holes, where it is further dissipated more effectively through the heat conduction plate and heat dissipation fins. Since several sets of heat dissipation fins are provided, the heat conduction plate has a larger heat dissipation area, effectively achieving heat conduction. Furthermore, because a copper sheet structure is embedded at the bottom of the heat conduction groove, heat can be more effectively transferred to the heat conduction components, thus ensuring the heat dissipation effect of the structure, thereby improving the service life of the outer spherical bearing and reducing material input.

[0018] Please see Figure 1-7 In this embodiment: an optimized heat dissipation structure for an outer spherical bearing housing includes: Mounting base 1, with mounting ends 2 at all four ends of the top of mounting base 1. Mounting ends 2 are composed of mounting nuts and threaded screws. Screw holes are opened at the four ends of mounting base 1 corresponding to the positions of mounting ends 2. Mounting ends 2 are used to achieve a stable connection between mounting base 1 and external equipment. The bearing seat 3 is located on the top of the mounting base 1. The bearing seat body 5 is provided on the top end face of the bearing seat 3 to achieve stable installation of the bearing. The mounting base 1 has a mounting groove 11 in the middle of the top end face, and the bearing base 3 has a slot 33 at the bottom. A circulation box 4 is provided between the mounting groove 11 and the slot 33. The bearing housing body 5 has an installation hole 51 inside, and an outer spherical bearing 6 is installed inside the installation hole 51. The heat conduction component 7 is disposed on both sides of the top end face of the bearing housing body 5 to achieve effective heat conduction.
[0019] This embodiment adopts a split structure. The bearing housing body 5 has fixed ends 53 fixedly connected to both sides of the bottom. The bearing seat 3 has a fixed groove 32 at the corresponding position. The size of the fixed end 53 is the same as the size of the fixed groove 32, and the connection between the two is achieved by welding. The bearing housing body 5 and the bearing seat 3 are separated by two sets of fixed ends 53 and a heat insulation cavity 54 is provided. A heat insulation cavity 54 is provided between the bottom of the bearing housing body 5 and the bearing seat 3 to improve air circulation. Compared with the existing bearing housing structure, this optimized heat dissipation structure has a better heat conduction effect. This embodiment is designed to form an effective circulating cooling structure: A circulating fan is fixedly installed inside the circulating box 4. The output end and return end of the circulating fan are respectively fixedly connected to the air guide pipe 41 and the return air pipe 42. The bottom end face of the bearing seat 3 has through holes 31 on both sides, and the air duct 41 and the return air duct 42 extend into the bearing seat body 5 through the through holes 31. The air inlet of the circulating fan is connected to an air inlet pipe, and the rear side of the circulating box 4 has a hole for accommodating the extension of the air inlet pipe. The bearing housing body 5 has an air hole 55 inside. The air hole 55 is specifically composed of an air inlet 551 and an air outlet 552, and is connected to the air duct 41 and the return air duct 42 respectively. The two are used to cooperate with the internal fan mechanism of the circulation box 4 to form a circulation air duct. The bearing housing body 5 has mounting holes 51 inside, and the front and rear sides are detachably mounted with limit plates 52 by bolts. Each set of limiting plates 52 is composed of four sets of arc-shaped panels arranged in a ring array. The outer spherical bearing 6 is set between two sets of limiting plates 52, and a flow cavity is provided at intervals in the wall of the mounting hole 51 to maintain the flow of cooling air. The internal circulating fan of the circulating box 4 operates, which introduces air through the air inlet pipe 41 into the air inlet hole 551 inside the bearing housing body 5, thereby ensuring that the circulating air can enter the mounting hole 51, thereby blowing the internally installed outer spherical bearing 6, carrying the heat on the surface of the outer spherical bearing 6 into the air outlet hole 552, and realizing the return air through the return air pipe 42, thus forming a circulating cooling structure, so that the heat inside the bearing housing body 5 can be circulated out, improving the heat dissipation effect of the structure; This embodiment aims to achieve more effective heat conduction treatment: The bearing housing body 5 has heat-conducting grooves 56 on both sides of the top end face, and heat-conducting components 7 are fixedly connected inside the two sets of heat-conducting grooves 56. A heat-conducting copper sheet is embedded at the bottom of the heat-conducting groove 56, and a heat dissipation hole 57 is provided through the bottom end face of the groove. Several sets of heat dissipation holes 57 are provided. The heat-conducting component 7 is specifically composed of a heat-conducting plate 71 and heat dissipation fins 72. Both the heat-conducting plate 71 and the heat dissipation fins 72 are made of copper. The heat-conducting plate 71 is fixedly installed inside the heat-conducting groove 56, and the two are closely fitted to achieve a tight connection. The heat dissipation fins 72 are fixedly installed on the top of the heat-conducting plate 71. The heat dissipation fins 72 are provided in several groups and are specifically in an inverted L-shaped structure to increase the heat conduction area. The outer spherical bearing 6 includes: Bearing outer sleeve 61 is disposed inside mounting hole 51; The bearing inner ring 62 is movably installed inside the bearing outer ring 61, and the two are slidably connected. An eccentric sleeve 63 is fixedly connected to the front end face of the bearing inner ring 62 for connecting the shaft structure to realize transmission. Fixing bolts 64 are provided around the outer perimeter of the eccentric sleeve 63. During the operation of the circulating cooling structure, the heat rises and enters the heat conduction groove 56 through the heat dissipation hole 57. The heat conduction plate 71 and heat dissipation fins 72 achieve more effective heat dissipation. Since there are several sets of heat dissipation fins 72, the heat conduction plate 71 has a larger heat dissipation area and can effectively conduct heat. In addition, since a copper sheet structure is embedded at the bottom of the heat conduction groove 56, the heat can be transferred to the heat conduction component 7 more effectively, thereby ensuring the heat dissipation effect of the structure, thereby improving the service life of the outer spherical bearing 6 and reducing material input.
[0020] The working principle and usage process of this invention are as follows: First, the outer spherical bearing 6 is installed inside the bearing housing body 5 through the mounting hole 51. After the installation of the limiting plate 52 is completed, a flow cavity is left on the outside of the outer spherical bearing 6. After the installation of the outer spherical bearing 6 is completed, the mounting seat 1 is fixedly installed in the external equipment through the mounting end 2. Its connecting rod structure is installed inside the eccentric sleeve 63, and a stable connection is completed by fixing bolts 64, so that the outer spherical bearing 6 can be put into use. During the operation of the outer spherical bearing 6, the circulating fan inside the circulation box 4 operates, which guides the circulating air into the air inlet 551 through the air guide pipe 41, and allows it to enter the flow cavity inside the mounting hole 51, blowing the outer spherical bearing 6 installed inside, carrying the heat on the surface of the outer spherical bearing 6 into the air outlet 552, and realizing the return air through the return air pipe 42, thereby forming a circulating cooling structure. During the operation of the above structure, heat rises and enters the heat conduction groove 56 through the heat dissipation hole 57, where it is more effectively dissipated through the heat conduction plate 71 and heat dissipation fins 72.
