Abstract
Description
Technical Field
[0001] This application relates to the field of bearing housing installation technology, and in particular to a support device for installing bearing housings. Background Technology
[0002] Large bearing housings need to be installed vertically during assembly. This process requires not only stable and reliable vertical support and positioning of the bearing housing, but also heating the mating surfaces of the bearing housing to approximately 150°C to achieve a heat-fitted connection.
[0003] In existing technology, when installing a bearing housing, it is first hoisted to a support position for positioning. Then, heating equipment needs to be introduced and precisely adjusted to the heating area of the bearing housing. After heating is completed, the heating equipment must be removed before the bearing housing can be hoisted onto the spindle for assembly. The entire process involves multiple repetitive hoisting, alignment, and equipment switching, resulting in a complex assembly process and low work efficiency. Utility Model Content
[0004] The purpose of this application is to provide a support device for installing bearing housings, which can effectively avoid the redundant steps of multiple hoisting, equipment switching and alignment in the traditional method, and significantly simplify the assembly process.
[0005] In a first aspect, this utility model provides a support device for mounting a bearing housing, comprising: Base; At least one support seat is arranged in a ring on the base, and the support seat is used to support the bottom surface of the bearing seat; A support frame is provided on the base and located within the annular area enclosed by the support base; At least one heating component is disposed on the support frame. The heating component includes a plurality of coil supports and a heating coil. The plurality of coil supports are arranged in a ring around the circumference of the support frame, and the heating coil is arranged around the coil supports. When the bearing housing is installed on the support base, the support frame and the heating assembly extend into the spindle hole of the bearing housing, and the heating coil of the heating assembly is used to heat the inner wall of the spindle hole.
[0006] Beneficial effects: This support device for installing bearing housings uses a hoisting system to flip the horizontally fed bearing housing with double hooks during installation, then hoists it onto the support device. This allows the support frame and heating assembly to pass through the spindle hole of the bearing housing, and the bottom surface of the bearing housing is placed on the support, ensuring the bearing housing is placed vertically. Subsequently, the heating assembly is activated, and its heating coil heats the inner wall of the spindle hole of the bearing housing. Once the bearing housing reaches the required process temperature, it is smoothly hoisted out, placed above the spindle, and fitted onto the spindle.
[0007] Because the support base is distributed in a ring and fits snugly against the bottom surface of the bearing housing, it provides stable support for the vertically placed bearing housing, avoids positioning misalignment when the bearing housing is placed on the support base, ensures that the bearing housing maintains a stable posture during heating and subsequent assembly, and improves the coaxiality accuracy of the bearing housing and spindle assembly.
[0008] The support device forms a stable load-bearing structure through the base and the annular support seat, while integrating the heating component onto the support frame. During bearing housing installation, the support frame and heating component can simultaneously extend into the spindle bore without subsequent adjustments, effectively avoiding redundant steps such as multiple hoisting, equipment switching, and alignment required in traditional methods, significantly simplifying the assembly process. The coordinated layout of the support seat and heating component ensures smooth transitions between each stage of the bearing housing process, from positioning and heating to final hoisting onto the spindle, reducing manual intervention and waiting time, thereby comprehensively improving assembly efficiency.
[0009] Furthermore, because the coil support of the heating component is arranged in a ring around the support frame, and the heating coil is positioned around the support and precisely corresponds to the bearing mating surface on the inner wall of the spindle hole, this structure can directly achieve directional heating of the target area after the bearing seat is installed, avoiding uneven temperature caused by heating deviation. At the same time, the coil is stably fixed by the support, reducing the risk of displacement during the heating process and ensuring the heating effect.
[0010] In one optional embodiment, the heating assembly further includes a ring-shaped connecting plate, which is detachably mounted on the support frame, and a plurality of coil supports are distributed circumferentially along the connecting plate and detachably mounted on the connecting plate.
[0011] Beneficial effects: The annular connecting plate provides a unified installation benchmark for the coil brackets, allowing multiple coil brackets to be evenly distributed along the circumference of the connecting plate, adapting to the heating requirements of the spindle holes of bearing seats of different specifications; at the same time, by replacing the annular connecting plate of different sizes, or adjusting the installation position of the coil brackets on the connecting plate, it is possible to adapt to heating coils of different outer diameters and heights, thereby meeting the heating requirements of mating surfaces of various types of bearing seats, avoiding the need to design heating components separately for a single specification of bearing seat, and improving the overall versatility of the support device.
[0012] In one optional embodiment, the coil support includes a mounting portion and a winding portion, the winding portion is disposed on the mounting portion, the outer wall of the winding portion is used to wind the heating coil, and the winding portion extends along the height direction of the support frame, and the mounting portion is detachably connected to the connecting plate.
[0013] Beneficial effects: The structure of the winding part extending along the height of the support frame allows the heating coil to form a continuous loop along the axial direction of the inner wall of the bearing housing spindle hole, ensuring full-height coverage heating of the bearing mating surface of the inner wall of the spindle hole and avoiding temperature gradient deviation caused by discontinuous heating areas; at the same time, the outer wall of the winding part is designed to wind the heating coil, which can guide the heating coil to form a regular arrangement and further improve the heating uniformity.
[0014] In one optional embodiment, a plurality of limiting grooves are provided on the outer wall of the winding portion, and the plurality of limiting grooves are spaced apart along the height direction of the winding portion, and the heating coil is embedded in the limiting grooves.
[0015] Beneficial effects: By setting multiple limiting grooves on the outer wall of the winding section, the limiting grooves can constrain the arrangement trajectory of the heating coils, preventing overlap or offset of the heating coils during the winding stage, or displacement due to thermal expansion and vibration during the heating process. This ensures that the heating coils remain uniformly distributed along the height direction of the winding section, thereby ensuring a consistent temperature distribution in the heating area of the bearing housing spindle hole, effectively avoiding problems of local overheating or insufficient heating.
[0016] In one optional embodiment, the mounting part is provided with a plurality of waist-shaped holes, and the connecting plate is provided with a plurality of connecting holes, the waist-shaped holes being provided in correspondence with the connecting holes.
[0017] Beneficial effects: Compared with round holes, the oblong hole has an adjustment margin along the length direction. When the mounting part is assembled with the connecting plate, even if there is a slight positional deviation between the oblong hole and the connecting hole, precise alignment can be achieved through the adjustment space of the oblong hole. There is no need to repeatedly adjust the overall position of the coil bracket or the connecting plate, which greatly reduces the alignment difficulty in the assembly process and improves assembly efficiency.
[0018] In one optional embodiment, two heating components are provided, and the two heating components are spaced apart along the height direction of the support frame; When the bearing housing is installed on the support, the two heating components heat the bottom and top of the bearing housing, respectively.
[0019] Beneficial effects: The two heating components spaced apart along the height of the support frame can simultaneously heat the bottom and top of the bearing housing, avoiding local temperature differences caused by the limited heating range of traditional single heating components. This ensures that the mating surfaces of the bottom and top of the bearing housing reach the required process temperature at the same time, effectively avoiding uneven thermal deformation of components caused by temperature differences between the upper and lower areas, ensuring the assembly accuracy when the bearing housing and bearing are interference-fitted, and meeting the process requirements for overall temperature consistency.
[0020] In one optional embodiment, a limiting hole is provided on the support base, and the limiting hole is provided corresponding to the mounting hole at the bottom of the bearing housing; When the bearing housing is installed on the support base, the bearing housing is connected to the support base by fasteners passing through the limiting hole and the mounting hole.
[0021] Beneficial effects: By passing fasteners through the limiting holes of the support base and the mounting holes at the bottom of the bearing housing, the bearing housing and the support base can be rigidly connected as a whole, which effectively limits the horizontal displacement or vertical swaying of the bearing housing caused by thermal expansion and vibration during the heating process, and at the same time prevents the bearing housing from shifting during hoisting, transportation and heating operations.
[0022] In one optional embodiment, a high-temperature resistant layer is provided on the support surface of the support base.
[0023] Beneficial effects: During the heating process of the bearing housing, heat is easily transferred from the bottom surface of the bearing housing to the support surface of the support base. The high-temperature resistant layer set on the support surface can effectively block the conduction of high temperature, avoiding problems such as material aging, deformation or strength reduction of the support base body due to long-term exposure to high temperatures, ensuring the structural stability of the support base and extending the service life of the entire support device.
[0024] In one optional embodiment, the support device further includes a plurality of guide members disposed on the base and configured to correspond to the wind turbine locking holes of the bearing housing.
[0025] Beneficial effects: The guide component is designed to correspond to the impeller locking hole of the bearing housing. During the process of hoisting the bearing housing to the support device, the impeller locking hole can slide down or fit along the outer wall of the guide component, forming a clear positioning guide benchmark. This eliminates the need for repeated manual adjustments to the horizontal position of the bearing housing to align with the support, allowing for rapid initial positioning of the bearing housing on the support device. This significantly reduces hoisting and alignment time and operational errors, improving assembly efficiency.
[0026] In one alternative embodiment, the insertion end of the guide is provided in a conical shape.
[0027] Beneficial effects: The guide insert is tapered, with its outer diameter gradually increasing from the top to the bottom, forming a smooth guide slope. During the bearing housing hoisting process, even if there is a slight positional deviation between the impeller locking hole and the guide, the tapered insert can guide the impeller locking hole to automatically correct its position through the slope. This allows for rapid fitting of the locking hole and the guide without the need for manual fine-tuning, significantly shortening the hoisting alignment time and improving assembly efficiency.

[0031] In related technologies, when installing bearing housings, the bearing housing is first hoisted to the support position for positioning. Then, heating equipment needs to be introduced and precisely adjusted to the heating area of the bearing housing. After heating is completed, the heating equipment must be removed before the bearing housing can be hoisted onto the spindle for assembly. The entire process involves multiple repetitive hoisting, alignment, and equipment switching, resulting in a complex assembly process and low work efficiency.
[0032] In the early stages of research and development for this application, to simplify the bearing housing assembly process and improve efficiency, the team first tried a "horizontal heating" solution. The heating equipment was placed directly into the horizontally positioned bearing housing, heated to the designated temperature, and then removed from the equipment before the bearing housing was hoisted to the spindle for assembly. This approach aims to utilize the horizontal arrival state of the bearing housing, eliminating the need for posture adjustment steps and theoretically shortening the operation process.
[0033] However, actual testing revealed a core flaw in this design: the horizontal bearing housing lacks stable positioning constraints, making it prone to shifting or tilting during heating due to its own weight and thermal expansion and contraction. This not only leads to misalignment between the heating equipment and the mating surface and uneven heating, but also increases the difficulty of aligning with the spindle during subsequent hoisting due to the inaccurate bearing housing posture, and may even cause collision risks, thus reducing efficiency and posing safety hazards.
[0034] Based on this, the inventors of this application have redesigned the support device for installing the bearing housing. During installation, the horizontally fed bearing housing is flipped using a hoisting device with double hooks and then hoisted onto the support device. This allows the support frame and heating assembly to pass through the spindle hole of the bearing housing, and the bottom surface of the bearing housing is placed on the support, ensuring the bearing housing is placed vertically. Subsequently, the heating assembly is activated, and its heating coil heats the inner wall of the spindle hole of the bearing housing. Once the bearing housing is heated to the required process temperature, it is smoothly hoisted out, placed above the spindle, and fitted onto the spindle.
[0035] Because the support base is distributed in a ring and fits snugly against the bottom surface of the bearing housing, it provides stable support for the vertically placed bearing housing, avoids positioning misalignment when the bearing housing is placed on the support base, ensures that the bearing housing maintains a stable posture during heating and subsequent assembly, and improves the coaxiality accuracy of the bearing housing and spindle assembly.
[0036] The support device forms a stable load-bearing structure through the base and the annular support seat, while integrating the heating component onto the support frame. During bearing housing installation, the support frame and heating component can simultaneously extend into the spindle bore without subsequent adjustments, effectively avoiding redundant steps such as multiple hoisting, equipment switching, and alignment required in traditional methods, significantly simplifying the assembly process. The coordinated layout of the support seat and heating component ensures smooth transitions between each stage of the bearing housing process, from positioning and heating to final hoisting onto the spindle, reducing manual intervention and waiting time, thereby comprehensively improving assembly efficiency.
[0037] Furthermore, because the coil support of the heating component is arranged in a ring around the support frame, and the heating coil is positioned around the support and precisely corresponds to the bearing mating surface on the inner wall of the spindle hole, this structure can directly achieve directional heating of the target area after the bearing seat is installed, avoiding uneven temperature caused by heating deviation. At the same time, the coil is stably fixed by the support, reducing the risk of displacement during the heating process and ensuring the heating effect.
[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.
[0039] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.
[0040] According to embodiments of the present invention, on the one hand, such as Figures 1 to 4 As shown, a support device for mounting a bearing housing is provided, including a base 100, a support base 200, a support frame 300, and a heating assembly 400.
[0041] Specifically, such as Figure 1 and Figure 2 As shown, at least one support base 200 is provided, and the support base 200 is arranged in a ring on the base 100. The support base 200 is used to support the bottom surface of the bearing housing 1000, so that the bearing housing 1000 is placed vertically on the base 100.
[0042] Specifically, such as Figure 2 As shown, the support frame 300 is mounted on the base 100, and the support frame 300 is located within the annular area enclosed by the support base 200.
[0043] Specifically, such as Figure 2 As shown, at least one heating assembly 400 is provided, wherein the heating assembly 400 is mounted on the support frame 300. The heating assembly 400 includes a coil support 410 and a heating coil 420. Multiple coil supports 410 are provided, and the multiple coil supports 410 are arranged in a ring around the support frame 300 along the circumference of the support frame 300. The heating coil 420 is arranged around the coil support 410.
[0044] Specifically, such as Figure 1 and Figure 2 As shown, when the bearing housing 1000 is installed on the support base 200, the support frame 300 and the heating component 400 are inserted into the spindle hole 1100 of the bearing housing 1000, and the inner wall of the spindle hole 1100 of the bearing housing 1000 is heated by the heating coil 420 on the heating component 400.
[0045] This support device for installing bearing housings involves using a hoisting device to flip the horizontally fed bearing housing 1000 using double hooks during installation. The bearing housing 1000 is then hoisted onto the support device, allowing the support frame 300 and heating assembly 400 to pass through the spindle hole 1100 of the bearing housing 1000. The bottom surface of the bearing housing 1000 is then placed on the support base 200, ensuring the bearing housing 1000 is placed vertically. Subsequently, the heating assembly 400 is activated, heating the inner wall of the spindle hole 1100 of the bearing housing 1000 through its heating coil 420. Once the bearing housing 1000 reaches the required process temperature, it is smoothly lifted out, hoisted above the spindle, and fitted onto the spindle.
[0046] Because the support base 200 is distributed in a ring and fits and conforms to the bottom surface of the bearing housing 1000, it provides stable support for the vertically placed bearing housing 1000, avoids the positioning offset problem when the bearing housing 1000 is placed on the support base 200, ensures that the bearing housing 1000 maintains a stable posture during heating and subsequent assembly, and improves the coaxiality accuracy of the bearing housing 1000 and the spindle assembly.
[0047] The support device forms a stable load-bearing structure through the base 100 and the annular support 200, while the heating component 400 is integrated into the support frame 300. When the bearing housing 1000 is installed, the support frame 300 and the heating component 400 can simultaneously extend into its spindle hole 1100 without subsequent adjustments, effectively avoiding the redundant steps of multiple hoisting, equipment switching, and alignment in traditional methods, and significantly simplifying the assembly process. The coordinated layout of the support 200 and the heating component 400 ensures smooth transitions between the positioning, heating, and final hoisting of the bearing housing 1000 to the spindle, reducing manual intervention and waiting time, thereby comprehensively improving assembly efficiency.
[0048] Furthermore, since the coil support 410 of the heating component 400 is arranged circumferentially along the support frame 300, and the heating coil 420 is arranged around the support and precisely corresponds to the bearing mating surface on the inner wall of the main shaft hole 1100, compared to the existing independent heating equipment that requires repeated position adjustments, this structure can directly achieve directional heating of the target area after the bearing seat 1000 is installed, avoiding uneven temperature caused by heating deviation. At the same time, the coil is stably fixed by the support, reducing the risk of displacement during the heating process and ensuring the heating effect.
[0049] Specifically, one support base 200 may be provided, arranged in a ring, and adapted to the bottom surface of the bearing housing 1000. Alternatively, multiple support bases 200 may be provided, arranged in a ring, so that the ring-shaped support bases 200 adapt to the bottom surface of the bearing housing 1000. In this embodiment, the number of support bases 200 is not specifically limited.
[0050] Specifically, the support frame 300 can be formed by detachably connecting multiple support structures. In this embodiment, the structure of the support frame 300 is not specifically limited.
[0051] Specifically, one or more heating components 400 may be provided, and multiple heating components 400 may be arranged at intervals on the support frame 300. In this embodiment of the application, the number of heating components 400 is not specifically limited.
[0052] In one embodiment, such as Figure 2As shown, the heating assembly 400 also includes a connecting plate 430, which has an annular structure. The connecting plate 430 is detachably mounted on the support frame 300, and a plurality of coil supports 410 are distributed circumferentially along the connecting plate 430, and the coil supports 410 are detachably connected to the connecting plate 430.
[0053] The annular connecting plate 430 provides a unified installation reference for the coil bracket 410, allowing multiple coil brackets 410 to be evenly distributed around the circumference of the connecting plate 430, adapting to the heating requirements of the spindle hole 1100 of different specifications of bearing housing 1000. At the same time, by replacing the annular connecting plate 430 of different sizes, or adjusting the installation position of the coil bracket 410 on the connecting plate 430, it can adapt to heating coils 420 of different outer diameters and heights, thereby meeting the heating requirements of mating surfaces of various types of bearing housing 1000, avoiding the need to design a separate heating component 400 for a single specification of bearing housing 1000, and improving the overall versatility of the support device.
[0054] The connecting plate 430 and the support frame 300, and the coil bracket 410 and the connecting plate 430 are all detachably connected. This not only makes it easy to adjust the position of each component as needed during device assembly, but also allows for the individual disassembly and replacement of damaged components when wear occurs (such as deformation of the coil bracket 410 or aging of the connecting plate 430), without the need to replace the entire heating component 400 or the support frame 300, thus reducing maintenance costs and replacement time.
[0055] Specifically, the connecting plate 430 and the support frame 300 can be detachably connected by means of bolt connection, snap connection or other means. In this embodiment of the application, no specific restrictions are placed on the detachable connection method between the connecting plate 430 and the support frame 300.
[0056] In one embodiment, such as Figure 4 As shown, the coil support 410 includes a mounting portion 411 and a winding portion 412, with the mounting portion 411 connected to the winding portion 412. The winding portion 412 is used to wind the heating coil 420, and extends along the height direction of the support frame 300. The mounting portion 411 is connected to the connecting plate 430 (as shown). Figure 2 (As shown) Detachable connection.
[0057] The structure of the winding part 412 extending along the height direction of the support frame 300 allows the heating coil 420 to form a continuous loop along the axial (height direction) of the inner wall of the main shaft hole 1100 of the bearing seat 1000, ensuring full-height coverage heating of the bearing mating surface of the inner wall of the main shaft hole 1100 and avoiding temperature gradient deviation caused by discontinuity of the heating area; at the same time, the outer wall of the winding part 412 is designed to wind the heating coil 420, which can guide the heating coil 420 to form a regular arrangement, further improving the heating uniformity.
[0058] Furthermore, due to the detachable connection between the mounting part 411 and the connecting plate 430, the coil bracket 410 can be flexibly replaced according to parameters such as the diameter of the spindle hole 1100 of different bearing seats 1000 and the height of the heating zone.
[0059] For example, by replacing the winding portion 412 of different lengths to adapt to mating surfaces of different axial dimensions, or by adjusting the circumferential position of the mounting portion 411 on the connecting plate 430 to optimize the coil distribution density, the device can be adapted to multiple specifications of bearing seats 1000 without modifying the main structure of the support frame 300 or the connecting plate 430.
[0060] In one embodiment, such as Figure 3 As shown, the outer wall of the winding portion 412 is provided with a plurality of limiting grooves 4121, wherein the plurality of limiting grooves 4121 are spaced apart along the height direction of the winding portion 412. When the heating coil 420 is wound on the outer wall of the winding portion 412, the heating coil 420 is embedded in the limiting groove 4121.
[0061] By providing multiple limiting grooves 4121 on the outer wall of the winding section 412, the limiting grooves 4121 can constrain the arrangement trajectory of the heating coils 420, preventing the heating coils 420 from overlapping or shifting during the winding stage, or from shifting due to thermal expansion or vibration during the heating process. This ensures that the heating coils 420 remain uniformly distributed along the height direction of the winding section 412, thereby ensuring a consistent temperature distribution in the heating area of the inner wall of the main shaft hole 1100 of the bearing housing 1000, effectively avoiding problems of local overheating or insufficient heating.
[0062] When assembling the heating coil 420, there is no need to repeatedly adjust the spacing and position of the heating coil 420. Simply embed the heating coil 420 into the corresponding limiting groove 4121 to quickly complete the winding and fixing, greatly reducing the time cost and operation error of manual alignment and improving the assembly efficiency of the heating component 400.
[0063] Specifically, the multiple limiting grooves 4121 can be evenly distributed at intervals along the height direction of the winding portion 412. In this embodiment, the distribution of the limiting grooves 4121 is not specifically restricted.
[0064] Specifically, the limiting groove 4121 can be configured as an arc-shaped groove, a rectangular groove, a trapezoidal groove, etc. In this embodiment, the shape of the limiting groove 4121 is not specifically limited.
[0065] In one embodiment, such as Figure 4 As shown, a plurality of oblong holes 4111 are provided on the mounting part 411 of the coil bracket 410, and a plurality of connecting holes are provided on the connecting plate 430, wherein the oblong holes 4111 are provided in correspondence with the connecting holes.
[0066] Compared to a circular hole, the oblong hole 4111 has an adjustment margin along its length. When the mounting part 411 is assembled with the connecting plate 430, even if there is a slight positional deviation between the oblong hole 4111 and the connecting hole (such as machining error or cumulative assembly error), precise alignment can be achieved through the adjustment space of the oblong hole 4111. There is no need to repeatedly adjust the overall position of the coil bracket 410 or the connecting plate 430, which greatly reduces the alignment difficulty in the assembly process and improves the assembly efficiency.
[0067] The adjustable waist-shaped hole 4111 allows for fine-tuning of the installation position of the coil bracket 410 on the connecting plate 430 (e.g., fine-tuning the circumferential angle and radial distance along the length of the waist-shaped hole 4111) according to different dimensions (such as hole diameter and height) of the spindle hole 1100 of the bearing housing 1000 or the winding requirements of the heating coil 420. This eliminates the need to replace the connecting plate 430 or re-machine the connecting hole, thus adapting to the heating requirements of bearing housings 1000 of different specifications and further enhancing the overall versatility and adaptability of the support device.
[0068] In one embodiment, such as Figure 2 As shown, there are two heating components 400, which are arranged vertically at intervals along the height of the support frame 300. When the bearing housing 1000 is installed on the support base 200, the two heating components 400 heat the bottom and top of the bearing housing 1000 respectively.
[0069] Two heating components 400 are spaced apart along the height of the support frame 300, which can simultaneously heat the bottom and top of the bearing housing 1000 (i.e., the two key mating surfaces of the inner wall of the spindle hole 1100 of the bearing housing 1000). This avoids the local temperature differences caused by the limited heating range of a traditional single heating component 400, and ensures that the mating surfaces of the bottom and top of the bearing housing 1000 reach the required process temperature at the same time. This effectively avoids the problem of uneven thermal deformation of components caused by temperature differences between the upper and lower areas, ensures the assembly accuracy of the bearing housing 1000 and the bearing when they are interference-fitted, and meets the process requirements for overall temperature consistency.
[0070] Two heating elements 400 simultaneously heat the bottom and top of the bearing housing 1000. Compared to heating in stages with a single heating element 400 (heating the bottom first and then the top, or vice versa), this significantly shortens the overall heating time. Simultaneous heating also prevents temperature loss in already heated areas during staged heating, reducing repeated temperature replenishment. While ensuring heating quality, this further reduces heating time in the bearing housing 1000 assembly process, indirectly improving overall assembly efficiency.
[0071] In one embodiment, such as Figures 1 to 3As shown, a limiting hole 210 is provided on the support base 200, and the limiting hole 210 is correspondingly provided with the mounting hole at the bottom of the bearing housing 1000. When the bearing housing 1000 is installed on the support base 200, the bearing housing 1000 and the support base 200 are connected by fasteners passing through the limiting hole 210 and connecting to the mounting hole.
[0072] By passing fasteners through the limiting hole 210 of the support base 200 and the mounting hole at the bottom of the bearing housing 1000, the bearing housing 1000 and the support base 200 can be rigidly connected as a whole, effectively limiting the horizontal displacement or vertical sway of the bearing housing 1000 caused by thermal expansion and vibration during the heating process, and preventing the bearing housing 1000 from shifting during hoisting, transportation and heating operations.
[0073] The corresponding positioning holes 210 and the mounting holes at the bottom of the bearing housing 1000 form a clear positioning reference. During assembly, the bearing housing 1000 can be quickly positioned on the support 200 simply by aligning the two with fasteners, reducing the error caused by manual adjustment.
[0074] In one embodiment, such as Figure 3 As shown, a high-temperature resistant layer is provided on the support surface of the support base 200.
[0075] During the heating process of bearing housing 1000, heat is easily transferred from the bottom surface of bearing housing 1000 to the support surface of support base 200. The high-temperature resistant layer set on the support surface can effectively block the conduction of high temperature, avoid problems such as material aging, deformation or strength reduction of support base 200 due to long-term exposure to high temperature, ensure the structural stability of support base 200 and extend the service life of the entire support device.
[0076] In high-temperature environments, if the support surface of the support base 200 directly contacts the bottom surface of the bearing housing 1000, the difference in their coefficients of thermal expansion may cause changes in the contact gap, or even local adhesion. The high-temperature resistant layer can reduce this thermal impact, maintain a stable contact between the support surface and the bottom surface of the bearing housing 1000, and prevent the bearing housing 1000 from shifting due to deformation or adhesion of the support surface, further ensuring positioning accuracy during heating and subsequent assembly processes.
[0077] Specifically, the high-temperature resistant layer can be a high-temperature resistant metal coating / plating, a high-temperature resistant polymer material, a high-temperature resistant inorganic non-metallic material, etc. In this embodiment, no specific restrictions are placed on the material type of the high-temperature resistant layer.
[0078] In one embodiment, such as Figure 1 and Figure 2 As shown, the support device is provided with multiple guide members 500, which are installed on the base 100 of the support device, and the multiple guide members 500 are arranged one-to-one with the impeller lock holes 1200 of the bearing seat 1000.
[0079] The guide component 500 is configured to correspond to the impeller locking hole 1200 of the bearing housing 1000. During the process of hoisting the bearing housing 1000 to the support device, the impeller locking hole 1200 can slide down or fit along the outer wall of the guide component 500, forming a clear positioning guide reference. Without the need for repeated manual adjustments to the horizontal position of the bearing housing 1000 to align with the support base 200, the initial positioning of the bearing housing 1000 on the support device can be quickly completed, significantly reducing hoisting and alignment time and operational errors, and improving assembly efficiency.
[0080] After the bearing housing 1000 is fitted onto the guide member 500, the guide member 500 can form a horizontal limiting constraint on the bearing housing 1000 through the impeller locking hole 1200, so as to prevent the bearing housing 1000 from being horizontally displaced due to vibration, thermal expansion or external force during the heating process.
[0081] It should be noted that the wind turbine lock hole 1200 is an inherent structure of the bearing housing 1000 (such as the wind turbine main shaft bearing housing 1000). The guide component 500 is designed to directly correspond to the wind turbine lock hole 1200. There is no need to additionally machine positioning holes on the bearing housing 1000 or the support device, thus avoiding damage to the original structure of the component. It can be adapted to various bearing housings 1000 with wind turbine lock holes 1200. There is no need to redesign the positioning structure for different models of bearing housings 1000, further improving the compatibility and versatility of the support device.
[0082] Specifically, the guide member 500 can be a guide post, which is set to correspond to the impeller locking hole 1200 of the bearing housing 1000. When the bearing housing 1000 is installed on the support device, the guide post passes through the impeller locking hole 1200 of the bearing housing 1000 to form a clear positioning guide reference.
[0083] In one embodiment, such as Figure 1 As shown, the insertion section of the guide 500 is set in a conical shape.
[0084] The guide member 500 has a tapered insertion end 510, with its outer diameter gradually increasing from the top to the bottom, forming a smooth guide slope. During the hoisting of the bearing housing 1000, even if there is a slight positional deviation between the impeller locking hole 1200 of the bearing housing 1000 and the guide member 500, the tapered insertion end 510 can guide the impeller locking hole 1200 to automatically correct its position through the slope. This allows for rapid fitting of the locking hole and the guide member 500 without the need for manual fine adjustment, significantly shortening the hoisting alignment time and improving assembly efficiency.
[0085] If the insertion end 510 of the guide member 500 is a right angle or a columnar structure, during the hoisting and fitting of the bearing housing 1000, misalignment may cause the locking hole to make hard contact with the guide member 500, resulting in collision and impact, which may cause wear on the edge of the locking hole or deformation of the guide member 500. The conical structure can buffer the force during the fitting process through the inclined surface, allowing the locking hole to slide slowly along the inclined surface and adapt to the guide member 500, avoiding damage to the wind turbine locking hole 1200 of the bearing housing 1000 and the guide member 500 from hard impact, and extending the service life of the components.
[0086] In one embodiment, such as Figure 1 As shown, the base 100 has multiple fork-tooth holes 110. In addition, the base 100 is also provided with multiple lifting rings 120.
[0087] The fork tooth hole 110 can be adapted to the insertion of fork teeth of forklifts and other handling equipment, making it easy to quickly move the entire support device to the designated work position according to the needs of the assembly site, without relying on large hoisting equipment, thus reducing the difficulty and cost of device relocation.
[0088] Multiple lifting rings 120 are reasonably distributed along the base 100 (usually in a symmetrical layout). When the support device needs to be moved as a whole (such as for inter-workshop transfer or installation at high-altitude workstations), the lifting equipment can be connected through the lifting rings 120 to ensure that the device is subjected to force evenly and to avoid tilting or structural deformation of the base 100 caused by single-point lifting. In addition, the setting of the lifting rings 120 also provides convenient lifting points for the installation, commissioning, maintenance and repair of the support device, improving the safety and efficiency of the overall operation.
