Description

Technical Field

[0001] This utility model relates to the field of bearing housing technology, and in particular to a bearing housing that is easy to maintain. Background Technology

[0002] In mechanical design, the ease of maintenance of bearing housings directly impacts equipment downtime and maintenance costs. For example, split bearing housings, through their separate top cover and base design, allow for bearing replacement without disassembling the drive shaft. Their typical structure uses bolt fastening, combined with O-rings or labyrinth seals, maintaining sealing while reducing maintenance difficulty.

[0003] Split bearing housings offer significant advantages in terms of ease of maintenance due to their detachable design. However, in practical use, they may also encounter a series of problems due to structural characteristics, installation processes, or operating environments. For example, since the top cover and base are mainly secured by bolts, insufficient bolt preload or harsh vibration environments may cause the bolts to loosen, leading to misalignment between the top cover and base, resulting in vibration and noise problems; it may also cause leakage at the sealing surface.

[0004] However, in existing technologies, maintenance and repair are usually carried out after the bolts have already loosened, causing vibration and noise problems in the bearing housing. It is impossible to detect and warn the workers immediately when the bolts become loose, resulting in the bearing housing not being able to respond in time, leading to problems such as severe wear or seal failure.

[0005] Therefore, it is necessary to solve the above problems by using a bearing housing that is easy to maintain. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] To address the problem in existing technologies that fail to detect and warn workers immediately when bolts become loose, resulting in delayed feedback when bearing housings become loose, leading to severe wear or seal failure, the following embodiments are proposed.

[0019] This utility model provides, for example Figures 1 to 4 The illustrated bearing housing, designed for easy maintenance, includes a bearing housing top cover 2 and a bearing housing base 1. The bearing housing base 1 is equipped with a bolt mounting seat 6, and the bearing housing top cover 2 is equipped with a retaining ring corresponding to the bolt mounting seat 6. A bolt body 3 passes through the retaining ring and is threaded into the bolt mounting seat 6. The bearing housing top cover 2 is fixedly mounted on the bearing housing base 1 via the bolt body 3, which is rotatably connected to the bolt mounting seat 6. A fastening assembly 4 is provided on the bolt body 3, and a detection assembly 5 is located at the bottom of the fastening assembly 4. After the bearing housing top cover 2 and the bearing housing base 1 are assembled, the space formed between them serves as a mounting hole for an external bearing.

[0020] By setting the fastening component 4, when the bolt body 3 becomes loose, the fastening component 4 can stabilize the connection between the bearing housing top cover 2 and the bearing housing base 1, and reduce the vibration of the bearing housing top cover 2 caused by the loosening of the bolt body 3. The fastening component 4, together with the detection component 5, can accurately identify whether the bolt body 3 is currently loose, so as to promptly provide feedback to the staff and warn them that the machine needs to be stopped for maintenance and repair, so as to avoid the problem of severe wear or seal failure caused by the failure to promptly report the loosening of the bearing housing.

[0021] like Figures 3-4As shown, the detection component 5 includes an angle sensor 501 mounted on the bottom surface of the fastening component 4, and a test plate 502 is provided at the sensing end of the angle sensor 501. It also includes a control console, which is connected to the angle sensor 501 via an electrical signal. The angle sensor 501 can transmit the measured data to the control console. After receiving the data, the control console issues a warning, alerting the operator that the bearing housing is loose and needs to be stopped for maintenance. The control console is for operators to view and operate, as well as control the operation and shutdown of the electronic components in this invention. A connecting post 406 is provided at the bottom end of the moving cylinder 402. A long through hole is opened on the test plate 502, and the connecting post 406 passes through the long through hole and slides along the long through hole.

[0022] It should be noted that after the fastening component 4 is installed, the measurement value of the angle sensor 501 is adjusted to zero through the main control panel, so that the initial value of the angle sensor 501 is zeroed in the initial state, which makes it easier to measure the angle change data value more accurately in the future.

[0023] During use, when the bolt body 3 becomes loose, it indicates that it is rotating. At the same time as the bolt body 3 rotates, it drives the snap-fit ​​top plate 405 to rotate synchronously. The snap-fit ​​top plate 405 drives the moving cylinder 402 to slide along the slide groove through the lifting column 403. At the same time as the moving cylinder 402 slides, it drives the test plate 502 to rotate through the connecting column 406. The angle sensor 501 detects the angle change and transmits the data change signal to the main control panel. After receiving the data, the main control panel starts the alarm program to remind the staff that the bearing seat is loose and that the machine needs to be stopped for maintenance in time.

[0024] By setting up angle sensor 501 and test plate 502, the fastening component 4 can detect whether the bolt body 3 is rotating in a timely manner, thereby detecting the current loosening of the bearing seat in a timely manner. This can promptly alert the staff and prevent the bearing seat from being worn out or the seal from failing to be maintained in time due to the loosening of the bearing seat.

[0025] like Figures 3-4As shown, the fastening assembly 4 includes a snap-fit ​​top plate 405 and a snap-fit ​​bottom plate 401. One end of the snap-fit ​​top plate 405 is provided with a through hole, which fits with the top end of the bolt body 3. One end of the snap-fit ​​bottom plate 401 is provided with a notch, which fits with the bottom of the bolt mounting seat 6. A movable cylinder 402 is slidably disposed on the snap-fit ​​bottom plate 401. A lifting column 403 is slidably disposed inside the movable cylinder 402. The snap-fit ​​top plate 405 is disposed on the top of the lifting column 403. A spring 404 is fixedly connected to the bottom of the lifting column 403. The end of the spring 404 away from the lifting column 403 is fixedly connected to the inner bottom end of the movable cylinder 402. A sliding groove is provided on the snap-fit ​​bottom plate 401. The bottom of the movable cylinder 402 passes through the sliding groove and slides along the sliding groove.

[0026] During use, the operator aligns the snap-fit ​​top plate 405 with the top of the bolt body 3, then pulls the moving cylinder 402 to slide down along the outer surface of the lifting column 403 until the moving cylinder 402 drives the snap-fit ​​bottom plate 401 to lock into the bottom of the bolt mounting seat 6. At the same time, the spring 404 is stretched, generating a contraction force, which stabilizes the connection between the snap-fit ​​top plate 405 and the snap-fit ​​bottom plate 401 at the bearing seat top cover 2 and the bearing seat base 1. That is, during the period from when the detection component 5 detects that the bolt body 3 has become loose until the operator stops the machine for maintenance, the snap-fit ​​top plate 405 and the snap-fit ​​bottom plate 401, with the assistance of the contraction force of the spring 404, can effectively stabilize the connection between the bearing seat top cover 2 and the bearing seat base 1, reducing vibration.

[0027] The working principle of this utility model is as follows: First, install the fastening component 4 and the detection component 5. The operator aligns the snap-fit ​​top plate 405 with the top of the bolt body 3 and installs it. Then, the moving cylinder 402 is pulled down along the outer surface of the lifting column 403 until the moving cylinder 402 drives the snap-fit ​​bottom plate 401 to be snapped into the bottom of the bolt mounting seat 6. At the same time, the spring 404 is stretched, generating a contraction force, so that the snap-fit ​​top plate 405 and the snap-fit ​​bottom plate 401 stabilize the connection between the bearing seat top cover 2 and the bearing seat base 1.

[0028] Secondly, the angle sensor 501 is set to zero. After the fastening assembly 4 is installed, the staff adjusts the initial measurement value of the angle sensor 501 to zero through the control panel.

[0029] Then, if loosening occurs, an immediate warning will be issued. When the bolt body 3 becomes loose, it indicates that it is rotating. At the same time as the bolt body 3 rotates, it drives the snap-fit ​​top plate 405 to rotate synchronously. The snap-fit ​​top plate 405 drives the moving cylinder 402 to slide along the slide groove through the lifting column 403. At the same time as the moving cylinder 402 slides, it drives the test plate 502 to rotate through the connecting column 406. The angle sensor 501 detects the angle change and transmits the data change signal to the main control panel. After receiving the data, the main control panel will activate the alarm program to remind the staff that the bearing seat is currently loose and that the machine needs to be stopped for maintenance in time.

[0030] Finally, the machine was shut down for maintenance and repair. The staff stopped the operation of the external bearing through the main control panel, removed the fastening component 4, and performed maintenance on the connection between the bearing housing top cover 2 and the bearing housing base 1.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
