Description

Technical Field

[0001] This utility model belongs to the field of bearing housing technology, and more specifically, it relates to a modular bearing housing that can be quickly disassembled and assembled. Background Technology

[0002] In practical applications of bearings, to ensure the operational stability of the bearings, as well as the coaxiality and operational accuracy of the shaft system, modular bearing housings are usually used to position, support, and protect the bearings. When the bearing housing is used in a humid environment, in order to avoid the hidden damage caused by moisture intrusion and corrosion, it is usually necessary to disassemble and inspect the bearing housing regularly to prevent the failure from escalating and to ensure the stable operation of the bearing housing and equipment.

[0003] For example, existing application number CN202221394800.2 relates to the field of mechanical parts, and in particular to a bearing housing, comprising: a housing, the housing being hollow and extending through both ends; a main shaft, the main shaft being located inside the housing; an end cap, the end cap being connected to one end of the housing; a bearing, the bearing being sleeved on the main shaft and connected between the housing and the main shaft, enabling the main shaft to rotate about its axis relative to the housing; and a sealing assembly, the sealing assembly being located between the bearing and the end cap, which solves the technical problem of lubricating oil leakage in the bearing housing; and achieves the technical effect of reducing lubricating oil leakage in the bearing housing.

[0004] Based on the above, when disassembling and inspecting modular bearing housings, it is necessary to use positioning bolts to separate the side cover from the bearing housing to enable internal inspection and protection. However, in humid environments, moisture can easily seep into the gaps between the bolts and threaded holes, causing corrosion. Local corrosion of the bolts and threaded holes not only easily leads to partial breakage of the bolt heads during disassembly, increasing the difficulty of disassembling the modular bearing housing, as well as maintenance costs and equipment downtime, but also easily causes the outer ring of the bearing to come out of the support module after the bolt breaks, resulting in shaft misalignment and collision with the housing, causing equipment downtime, component scrapping, and endangering the safety of operators. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a modular bearing housing that can be quickly disassembled and assembled. This solves the problem that in humid environments, moisture easily seeps into the gap between the bolts and threaded holes, causing corrosion of the bolts and threaded holes. After local corrosion of the bolts and threaded holes, not only is it easy for the bolt heads to break during disassembly, increasing the difficulty of disassembling the modular bearing housing, as well as maintenance costs and equipment downtime, but it is also easy for the outer ring of the bearing to come out of the support module after the bolt breaks, causing the shaft to shift and collide with the housing, resulting in equipment downtime, component scrapping, and endangering the safety of operators.

[0006] The purpose and effect of this utility model, a modular bearing housing that can be quickly disassembled and assembled, are achieved by the following specific technical means:

[0007] A modular bearing housing capable of quick assembly and disassembly includes a bearing housing shell, protective side plates, positioning bolts, transmission auxiliary rings, a sealing auxiliary mechanism, and an assembly / disassembly auxiliary mechanism. Two protective side plates are symmetrically mounted on the outer end faces of the bearing housing shell. Multiple threaded mounting holes are circumferentially arranged on the inner sides of the protective side plates and the bearing housing shell. The outer end faces of the threaded mounting holes have a conical hole structure. Multiple positioning bolts are threadedly connected to the outer sides of the multiple threaded mounting holes. Multiple transmission auxiliary rings are circumferentially arranged and rotatably connected to the inner sides of the protective side plates, with the transmission auxiliary rings aligned with the threaded mounting holes. The sealing auxiliary mechanism is located between the mating surfaces of the bearing housing shell and the protective side plates. The assembly / disassembly auxiliary mechanism is located at the inner end of the protective side plates. The inner end of the protective side plates has a hollow structure, and a filling port is provided at the top of the protective side plates. A discharge groove is provided inside the threaded mounting holes of the protective side plates.

[0008] Furthermore, oil reservoir rings are fixedly connected to the outer sides of the left and right ends of the bearing housing; an oil guide port is provided between the oil reservoir ring and the contact surface of the bearing.

[0009] A rubber ring is fixedly connected to the center of the inner side of the protective side plate.

[0010] Furthermore, the sealing auxiliary mechanism includes: a sealing auxiliary ring and a positioning protrusion. There are two sealing auxiliary rings, which are respectively fixedly connected between the two mating surfaces of the protective side plate and the bearing housing. There are multiple positioning protrusions, which are circumferentially arranged and fixedly connected to the outside of the sealing auxiliary ring. A positioning groove is provided at the alignment position between the bearing housing and the positioning protrusion.

[0011] Furthermore, the disassembly and assembly auxiliary mechanism includes: limiting protrusions and limiting grooves. There are multiple limiting protrusions, which are respectively fixedly connected to the inner side of multiple transmission auxiliary rings. There are multiple limiting grooves, which are respectively opened on the outer side of multiple positioning bolts. The limiting grooves and the limiting protrusions are aligned and are the same size.

[0012] Furthermore, the disassembly and assembly auxiliary mechanism also includes: transmission gears and drive gear rings. There are multiple transmission gears, which are coaxially fixedly connected to the outer sides of multiple transmission auxiliary rings. There are two drive gear rings, which are rotatably connected to the inner ends of two protective side plates. The drive gear rings on the left and right sides mesh with the transmission gears.

[0013] Furthermore, the disassembly and assembly auxiliary mechanism also includes: a limiting guide ring, there are two limiting guide rings, the two limiting guide rings are respectively fixedly connected to the inner ends of the two drive gear rings, and the longitudinal cross section of the limiting guide ring is a convex structure; multiple guide grooves are arranged circumferentially on the inner side of the transmission auxiliary ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model achieves functional optimization and upgrade through the coordinated cooperation of multiple components. The oil storage rings on the outer sides of the left and right ends of the bearing housing cooperate with the oil guide ports on the bearing contact surface, which can more conveniently lubricate the bearing. The lubricating oil can be accurately guided to the bearing parts that need lubrication without complicated operations, effectively ensuring the lubrication effect of the bearing and extending the service life of the bearing. The rubber ring at the center of the inner side of the protective side plate can play a certain role in buffering and sealing the internal structure of the bearing housing, further enhancing the overall protective performance.

[0016] When in use, this utility model employs a sealing auxiliary mechanism, which not only ensures that the protective side plate and the threaded mounting hole of the bearing housing are automatically aligned on the same axis during assembly, improving the smoothness of the positioning bolt assembly, but more importantly, the sealing auxiliary ring significantly enhances the sealing effect between the two, slows down the rate at which moisture seeps into the gap between the positioning bolt and the threaded mounting hole, and effectively reduces bolt corrosion.

[0017] In use, this invention employs a disassembly and assembly auxiliary mechanism. Rotating any one of the positioning bolts drives multiple transmission gears and the positioning bolt to rotate simultaneously via a drive gear ring. This eliminates the cumbersome traditional method of operating each bolt individually, significantly shortening disassembly and assembly time and improving the efficiency of disassembly and assembly of modular bearing housings. Especially in scenarios requiring frequent disassembly and inspection, it effectively reduces equipment downtime. Furthermore, during disassembly and assembly, it automatically guides rust remover to the space between the threaded mounting hole and the positioning bolt, providing continuous protection for the bolt and threaded hole, preventing rust on the positioning bolt and reducing the likelihood of localized bolt head breakage during disassembly. This not only reduces the difficulty of disassembling the modular bearing housing but also reduces increased maintenance costs due to bolt breakage. It also prevents serious consequences such as shaft misalignment and collision with the housing caused by the bearing outer ring detaching from the support module, ensuring stable equipment operation and providing more reliable safety for operators.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0027] Example 1: As shown in the attached document Figure 1 To be continued Figure 3 As shown:

[0028] This utility model provides a modular bearing housing that can be quickly disassembled and assembled, including a bearing housing shell 1, protective side plates 2, positioning bolts 3, transmission auxiliary rings 4, and a sealing auxiliary mechanism. There are two protective side plates 2, which are symmetrically installed on the outer end faces of the bearing housing shell 1.

[0029] Among them, oil reservoir rings 101 are fixedly connected to the outer sides of the left and right ends of the bearing housing 1; an oil guide port is provided between the oil reservoir ring 101 and the contact surface of the bearing.

[0030] A rubber ring 201 is fixedly connected to the center of the inner side of the protective side plate 2.

[0031] The sealing auxiliary mechanism includes: a sealing auxiliary ring 5 and a positioning protrusion 501. There are two sealing auxiliary rings 5, which are fixedly connected between the two mating surfaces of the protective side plate 2 and the bearing housing 1, respectively. There are multiple positioning protrusions 501, which are arranged circumferentially and fixedly connected to the outside of the sealing auxiliary ring 5. A positioning groove 502 is provided at the alignment position between the bearing housing 1 and the positioning protrusion 501.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In use, the oil storage ring 101 and the oil guide port improve the convenience of lubricating the bearing. When assembling the protective side plate 2 with the bearing housing 1, after aligning the positioning groove 502 and the positioning protrusion 501, pressing the protective side plate 2 inward makes the threaded mounting hole 203 of the protective side plate 2 and the threaded mounting hole 203 of the bearing housing 1 automatically keep on the same axis, which improves the smoothness of assembling and positioning the bearing housing 1 and the protective side plate 2 with the positioning bolt 3. The sealing auxiliary ring 5 ensures the sealing effect between the bearing housing 1 and the protective side plate 2 and reduces the seepage of moisture into the positioning bolt 3 and the threaded mounting hole 203.

[0034] Example 2: As shown in the attached document Figure 2 To be continued Figure 6 As shown:

[0035] Based on Embodiment 1, it also includes a disassembly and assembly auxiliary mechanism, which is located at the inner end of the protective side plate 2; the inner end of the protective side plate 2 is a cavity structure, and a filling port 202 is opened at the top of the protective side plate 2; a discharge groove is opened inside the threaded mounting hole 203 of the protective side plate 2.

[0036] The disassembly and assembly auxiliary mechanism includes: a limiting protrusion 401 and a limiting groove 402. There are multiple limiting protrusions 401, which are fixedly connected to the inner side of multiple transmission auxiliary rings 4 respectively. There are multiple limiting grooves 402, which are respectively opened on the outer side of multiple positioning bolts 3. The limiting grooves 402 and the limiting protrusions 401 are aligned and are the same size.

[0037] The disassembly and assembly auxiliary mechanism also includes: a transmission gear 403 and a drive gear ring 404. There are multiple transmission gears 403, which are coaxially fixedly connected to the outer side of multiple transmission auxiliary rings 4.

[0038] The disassembly and assembly auxiliary mechanism also includes: a limiting guide ring 405, there are two limiting guide rings 405, the two limiting guide rings 405 are respectively fixedly connected to the inner ends of the two drive gear rings 404, and the longitudinal section of the limiting guide ring 405 is a convex-shaped structure; multiple guide grooves 406 are arranged circumferentially on the inner side of the transmission auxiliary ring 4.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In use, the rust remover is introduced into the inner end of the protective side plate 2 through the filler port 202. The cavity structure of the protective side plate 2 stores the rust remover. After the limiting protrusion 401 and the limiting groove 402 are aligned, multiple positioning bolts 3 are installed into the threaded mounting holes 203. When any positioning bolt 3 is rotated, the drive gear ring 404 drives multiple transmission gears 403 and the positioning bolt 3 to rotate simultaneously, which improves the disassembly and assembly efficiency of this modular bearing box. At the same time, during the rotation of the transmission auxiliary ring 4, when the guide groove 406 and the discharge groove are aligned, the rust remover automatically flows between the threaded mounting hole 203 and the positioning bolt 3, which greatly avoids the corrosion of the positioning bolt 3 and the local breakage of the positioning bolt 3.
