Description

Technical Field

[0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a waterproof bearing box. Background Art

[0002] Currently, there are relatively mature methods for treating rust on steel plates. The original pickling method has been abandoned in favor of a more environmentally friendly brushing method. One of the most efficient brushing methods is to pass the steel plate through two scale-breaking rollers arranged one above the other. The high-speed rotating scale-breaking rollers use the abrasive on their surfaces to simultaneously grind the upper and lower surfaces of the steel plate, thereby removing the oxide scale on the steel plate surface.

[0003] The invention patent with application number 202023341331.1 discloses a closable shaft seat drive device. The document records that a front baffle and a rear baffle are provided at the front end and tail end of the base, and two side plates are provided on both sides of the base, and a bottom plate is connected between the bottoms of the two side plates; and a bearing seat is slidably connected to the base, which is used to connect the bearing seat supporting the descaling roller; a partition arranged at the tail end of the bearing seat and staggered with the bottom plate makes it possible that when the bearing seat moves to abut against the front baffle, each side plate, front and rear baffle, bottom plate and partition form a relatively sealed interval with the base.

[0004] If the device in the above scheme is rotated 180 degrees, that is, turned upside down, the scale-breaking rollers used for grinding and brushing can be supported on the upper and lower surfaces of the steel plate through the device, and the steel plate passing between the two scale-breaking rollers can then be brushed. However, the problem with this is that the steel plate grinding and brushing operation involves water, and the bottom plate and the partitions are staggered, leaving a gap. Although the hanging method described in the public document makes it difficult for water to splash into the enclosed area, when inverted, water can easily flow into the interior through the gap, causing negative effects. Therefore, a more sealed box is needed. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a waterproof bearing box for connecting a brush roller, which is formed by tightly splicing a front plate, a rear plate, a top plate, a bottom plate and left and right side plates to form a sealed box body for waterproofing, and the movable bearing seat provided inside it can seal the opening with the elastic seal when extended outward, so that the box body is still in a relatively sealed state, thereby achieving a waterproof effect.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] The cam is secured to the rear of the chassis and is secured to the chassis by a secure seal which allows the chassis to move relative to the chassis and to the chassis base.

[0008] The front, top, bottom, and left and right side panels are welded together into a single piece, eliminating gaps that may exist in traditional splicing methods and improving overall waterproofing. The rear panel is connected with screws, which reduces the amount of water splashing onto the bearing housing and facilitates installation and removal of the movable bearing seat within the bearing housing. Because the system operates in a water-exposed environment, when the movable bearing seat extends out of the working opening, the elastic seal cooperates with the movable bearing seat to seal the opening. Its elastic deformation allows it to conform more closely to the bearing housing at the working opening when subjected to pressure, further enhancing waterproofing.

[0009] The drive box is also formed by integral welding, and its sealing is better. At the same time, the front opening can use the rear plate to form an independent sealing area, which reduces the use of materials and reduces possible gaps. If a plate is set at the opening position for sealing, the drive box may have a gap at the connection position, and the plate may have a gap when connected to the bearing box body. Directly connecting the top plate and the side plate to the rear plate can indirectly improve the waterproof performance.

[0010] Preferably, the connecting top plate and the rear plate are connected by a flange fit, which means that one end of the connecting top plate at the opening of the drive box extends upward to form a flange, and the flange is fit connected to the rear side of the rear plate; the two connecting side plates are connected by a covering connection with the rear plate, which means that the connecting side plates extend forward to the left and right side walls of the rear plate and are fit connected therewith.

[0011] The flanged edges of the top panel increase the connection area with the rear panel, improving both connection stability and sealing performance. The extended side panels wrap around the left and right edges of the rear panel, creating a close fit and further enhancing the seal. Directly connecting the side panels to the rear panel's backside results in a less airtight connection than with a wrap-around connection.

[0012] Preferably, the tail end of the movable bearing seat is connected to a flange, the elastic seal is connected to the side wall of the flange, and the flange and the front plate are squeezed together to form a pressure against the elastic seal.

[0013] The elastic deformation of the elastic seal is achieved through the extrusion of the flange and the front plate. In the working state, the flange will move toward the working port position together with the movable bearing seat. The movable bearing seat extends out of the working port to support the brush roller, and the flange presses the elastic seal against the side wall of the front plate, causing it to deform, thereby further improving the tightness of the abutment and making the sealing performance better.

[0014] Preferably, an annular abutment portion is provided on the inner side of the front plate at a position corresponding to the working port to form a secondary sealing abutment with the elastic seal; when the elastic seal is driven to move forward, it is elastically deformed along its radial direction due to the extrusion of the flange and the front plate, and then abuts and seals with the inner ring wall of the abutment portion.

[0015] The abutment portion is provided to improve the sealing performance at the working port. When the elastic seal is deformed, due to the limitation of the front plate and the flange, it can only deform in its radial direction, so that the deformed extended part abuts against the inner ring wall of the abutment portion, further improving the sealing performance.

[0016] Preferably, the front plate is provided with an outflow hole at the bottom of the working port for draining away water splashed onto the elastic seal and the periphery of the working port.

[0017] The outflow hole can timely guide away the water splashed onto the elastic seal and the working port in the working state, preventing the water from accumulating there and then slowly soaking and flowing into the interior of the bearing box body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The front plate, rear plate, top plate, bottom plate and left and right side plates are tightly connected to form a sealed box body, which can effectively prevent water from splashing into the interior; the cooperation between the movable bearing seat and the elastic seal can block the opening, which not only facilitates the extension of the movable bearing seat, but also keeps the box body in a relatively sealed state, effectively waterproofing;

[0020] The drive box further improves the sealing of the connection through the flange connection of the top plate and the cladding connection of the side plate, further improving the waterproof performance;

[0021] The arrangement of the abutting portion and the annular structure enable the elastic sealing member to form a secondary abutting seal with the inner ring wall after being deformed by the abutting pressure, thereby improving the waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0032] The following is a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0033] In this embodiment, a waterproof bearing box for connecting a brush roller is specifically disclosed. Figure 1-9 As shown, its specific structure includes a bearing box body 1 arranged on a horizontally movable beam 2, and a brush roller connecting mechanism 4 for connecting to a supporting brush roller 5 is provided in the bearing box body 1. The brush roller connecting mechanism 4 includes a sliding seat 401 that can slide relatively along the length direction of the bearing box body 1 and a movable bearing seat 402 connected to the side wall of the sliding seat 401. The sliding seat 401 and the movable bearing seat 402 are arranged in a front-to-back manner along the length direction of the bearing box body 1, and a shaft support device for connecting to the shaft head of the brush roller 5 is passed through the sliding seat 401 and the movable bearing seat 402; the rear side of the bearing box body 1 is also sealed and connected to a drive box 115 with a built-in drive device, and the drive device is passed through The rear side wall of the bearing box body 1 and its output end are connected to the sliding seat 401, and the interior of the bearing box body 1 and the interior of the drive box 115 are isolated by the rear side wall of the bearing box body 1 to form two independent spaces that do not affect each other; the sliding seat 401 drives the shaft support device to move synchronously through the drive device to dock and install or loosen and replace the brush roller 5; the front side of the bearing box body 1 is also provided with a working port 106. When working, the movable bearing seat 402 is extended from the working port 106 and is in a sealed state with the working port 106 to prevent water from entering the bearing box body 1; when replacing the brush roller 5, the movable bearing seat 402 can be retracted into the bearing box body 1 to avoid collision.

[0034] When in use, the bottom surface of the bearing box body 1 is installed correspondingly to the top surface of the beam 2, and the fixed bearing seat 3 is also pre-installed on the beam 1. The two can cooperate to connect the shaft heads at both ends of the supporting brush roller 5 respectively, and the above device is arranged below the steel plate feed; similarly, the above device can also be rotated 180 degrees and arranged inverted above the steel plate feed route. When the steel plate needs to be brushed, the movement of the brush roller 5 is controlled by turning on and off the drive motor 6 that drives the brush roller 5 to rotate.

[0035] During the brushing process, water needs to be sprayed on the steel plate to wash away the oxide scale and abrasive debris from the steel plate surface. On the other hand, it can also cool the grinding area to prevent frictional overheating that affects the brushing effect of the abrasive. Therefore, if water splashes into the bearing box body 1 or the drive box 115 during the steel plate grinding process, it may cause negative effects.

[0036] In order to ensure the waterproof performance of the bearing box body 1, the bearing box body 1 is formed into an integral welded part by the front plate 101, the top plate 103, the bottom plate 104 and the left and right side plates 105, and then the sliding seat 401 and the movable bearing seat 402 are installed in the bearing box body 1. The output end of the driving device installed in the drive box 115 first passes through the rear plate 102 and then connects to the sliding seat 401, and then the rear plate 102 is tightly connected to the rear side of the welded part by screws. Similarly, the drive box 115 is also tightly connected to the rear plate 102 by screws, and the joints are coated with sealant to ensure waterproof performance. The drive box 115 is arranged on the rear side of the bearing box body 1. On the one hand, it is convenient to install the drive device, and on the other hand, it is to keep away from the brush roller 5. The bearing box body 1 first blocks the splashing water, which also provides a certain protection for the drive box 115, but the drive box 115 still needs to have sealing performance. The drive box 115 is formed by welding a connecting top plate 1151, two connecting side plates 1152 and connecting plates located at the bottom and rear sides, and an opening is left on the front side. The drive box 115 forms a closed box body through the connection with the rear plate 102; at the same time, in order to ensure the sealing of the connection, the connecting top plate 1151 extends upward to form a flange 1153, and the flange 1153 can increase the contact area with the rear plate 102. The fitting connection with the rear plate 102 can improve the sealing of the top of the drive box 115. At the same time, the two connecting side plates 1152 also extend forward to the left and right side walls of the rear plate 102 and are fit connected therewith, which further ensures the sealing of the drive box 115 when connected to the rear plate 102.

[0037] Since the movable bearing seat 402 needs to extend outward from the bearing box body 1 and cooperate with the fixed bearing seat 3 to support the brush roller 5, a working port 106 is opened on the front plate 101, that is, on the front side of the bearing box body 1; the sliding seat 401 can move in the bearing box body 1, and the movable bearing seat 402 is fittedly connected to the side wall of the sliding seat 401, so that the movable bearing seat 402 can extend outward from the working port 106, but it should be noted that the movable bearing seat 402 needs to maintain a sealed state with the working port 106 when extending outward to prevent water from entering the interior of the bearing box body 1. The drive box 115 is sealed and connected to the rear side of the bearing box body 1. On the one hand, it is farther away from the water spraying position than the bearing box body 1. On the other hand, the bearing box body 1 also plays a certain shielding role. The internal drive device is penetrated through the rear side wall of the bearing box body 1. Therefore, even when the movable bearing seat 402 is extended outward and the sealing state with the working port 106 fails, the bearing box body 1 is flooded with water, and the water that enters will not enter the drive box 115 to affect the drive device, so that the impact is minimized.

[0038] Because this type of brushing method mainly uses the abrasive on the brush roller 5 for brushing, the frequency of replacing the brush roller 5 is still relatively high. Therefore, the traditional exposed movable bearing seat 402 is prone to collision when changing the roller. The sliding seat 401 and the movable bearing seat 402 in this embodiment are both located in the bearing box body 1 when changing the roller, so they can play a good protective role. Although the working port 106 is in an exposed state at this time, because brushing is not required at this time, no water spraying is required and no abrasive debris and oxide scale will be generated.

[0039] When brushing the steel plate, if the brush roller 5 is installed in the traditional production method, the brush roller 5 is connected to the middle position of the movable bearing seat 402; but the shaft support device in this embodiment is located above the central axis of the movable bearing seat 402 to form an eccentric setting, and the height of the brush roller 5 is increased so that when the crossbeam 2 moves horizontally to drive the bearing box body 1 to move, the top surface of the bearing box body 1 can avoid the steel plate to be polished; the movable bearing seat 402 has an elliptical cross-section and is arranged vertically on the front side of the sliding seat 401 to increase the connection area between the movable bearing seat 402 and the side wall of the sliding seat 401 and the stability of the movable bearing seat 402 when supporting the brush roller 5.

[0040] If the traditional installation method is used, the height of the brush roller 5 relative to the bearing housing body 1 will be reduced. As the abrasive on the surface of the brush roller 5 is worn away during grinding, the height difference between the steel plate on which it is ground and the top of the bearing housing body 1 will gradually decrease. At this time, when the entire crossbeam 2 is moved out from under the steel plate along the width direction of the steel plate, it is easy for the steel plate and the top surface of the bearing housing body 1 to interfere with each other. However, the eccentric setting of the bearing support device can avoid this situation. In addition, the elliptical setting of the movable bearing seat 402 can also increase the connection area with the sliding seat 401, thereby improving the stability of the connection. Because the brush roller 5 is heavy, the movable bearing seat 402 has a prying action on the movable bearing seat 402 when supporting the brush roller 5. If a traditional bearing seat is used, it is prone to jitter and instability during operation after installation. The elliptical setting, on the one hand, provides a connection point for the eccentric setting of the bearing support device, and on the other hand, the elliptical lower half supports the prying action of the brush roller 5, improving stability.

[0041] Although the movable bearing seat 402 can also be set in a circular shape and the shaft support device can be set eccentrically, compared with the elliptical setting, the circular shape will occupy more horizontal space, making the volume of the bearing box body 1 larger.

[0042] In this embodiment, when the movable bearing seat 402 is installed to the bearing box body 1 and extends outward and downward for work, the difference D between the height of the upper end of the movable bearing seat 402 and the height of the top of the bearing box body 1 is 4-5 cm, preferably 4 cm; the height of the highest point of the circumferential surface of the brush roller 5 and the height L of the top of the movable bearing seat 402 are 14-16 cm, preferably 14 cm. This ensures that the top of the bearing box body 1 will not interfere with the steel plate.

[0043] The shaft support device includes a sleeve 404 that is inserted into the sliding seat 401 and the movable bearing seat 402 to improve the stability of the connection between the sliding seat 401 and the movable bearing seat 402. An inner core tube 405 is rotatably connected to the sleeve 404. The end of the inner core tube 405 has a connecting port 406 for connecting to the shaft head of the brush roller 5. The inner core tube 405 extends outward from the outside of the movable bearing seat 402 and the extended end is also sleeved with a brush roller rotating shaft sleeve 403.

[0044] Since the movable bearing seat 402 and the sliding seat 401 in this embodiment are arranged to be connected in a front-to-back manner, instead of hanging the movable bearing seat 402 under the sliding seat 401 as in the traditional method, the sleeve 404 is passed through the movable bearing seat 402 and the sliding seat 401. On the one hand, the length of the sleeve 404 and the inner core tube 405 is made longer, thereby improving the strength of the two themselves; on the other hand, the connection between the movable bearing seat 402 and the sliding seat 401 is made more stable, and the prying of the movable bearing seat 402 by the brush roller 5 is further balanced.

[0045] The sealing state between the movable bearing seat 402 and the working port 106 when the movable bearing seat 402 is extended is achieved in the following manner: an annular abutting portion 111 is provided at the position of the inner side wall of the bearing box body 1 surrounding the working port 106, and a pressing interval 112 is formed in the radial direction between the inner ring wall of the abutting portion 111 and the periphery of the working port 106; an elastic sealing member 113 located on the side wall of the sliding seat 401 is sleeved on the circumferential surface of the movable bearing seat 402, and the elastic sealing member 113 can be a sealing ring made of rubber, or a flange 411 is connected to the tail end of the movable bearing seat 402. The elastic seal 113 is connected to the side wall of the flange 411; when the bearing seat 402 is moved and extended, the elastic seal 113 can enter the pressing zone 112 and abut against the side wall of the bearing box body 1 at the working port 106; after the elastic seal 113 is deformed by abutment, its periphery abuts against the inner ring wall of the abutting portion 111 to prevent water from entering the bearing box body 1; the bearing box body 1 is provided with an outflow hole 114 at the bottom of the working port 106; in the working state, the outflow hole 114 can guide and discharge water splashed onto the elastic seal 113 and the periphery of the working port 106.

[0046] The elastic seal 113 is made of rubber and has a certain degree of deformation capability. When the movable bearing seat 402 extends from the working port 106 to support the brush roller 5, the elastic seal 113 also moves therewith, entering the pressing zone 112 during the movement. When pressing against the inner side wall of the bearing box body 1, the sliding seat 401 and the inner side wall of the bearing box body 1 squeeze the elastic seal 113, causing it to deform and extend radially, thereby abutting against the inner annular wall of the abutting portion 111, further improving the sealing effect.

[0047] The driving device is an oil cylinder 409, the piston rod of the oil cylinder 409 passes through the side wall of the bearing box body 1 and is connected to the rear side of the sliding seat 401; the bearing box body 1 is also provided with two parallel guide rods 410 along its length direction and spaced apart from the bottom of the bearing box body 1, and the two ends of the guide rod 410 are respectively connected to the front and rear inner walls of the bearing box body 1, and the bottom of the sliding seat 401 is mounted on the guide rod 410 and can slide axially along the guide rod 410. The sliding seat 401 forms an empty area with the bottom of the bearing box body 1 through the installation of the guide rod 410.

[0048] The drive of the oil cylinder 409 will be more stable. The oil cylinder 409 is arranged in the drive box 115. It is relatively independent of the components in the bearing box body 1 and cooperates with each other. The piston rod of the oil cylinder 409 passes through the side wall of the bearing box body 1, thereby driving the sliding seat 401 to move. The guide rod 410 provides a connection point for the sliding seat 401 on the one hand, making the sliding seat 401 more stable when sliding. On the other hand, it also makes the sliding seat 401 and the movable bearing seat 402 in a suspended state inside the bearing box body 1, located above the bottom of the bearing box body 1. In actual production, the elastic seal 113 will age and break after long-term use. This may cause the sealing effect to be poor when the movable bearing seat 402 is extended, and water will enter the bearing box body 1. However, the mounted sliding seat 401 and the movable bearing seat 402 will not be exposed to the entering water, and also play a waterproof role. Since the drive box 115 is blocked by the rear side wall of the bearing box body 1, it will not be affected by water.

[0049] The bearing box body 1 is also provided with a drainage system at the bottom to discharge water entering the bearing box body 1 when the seal fails; the drainage system includes a drainage port 110 opened at the bottom of the bearing box body 1, and a plurality of partition plates 107 are vertically provided on the bottom plate of the bearing box body 1. The partition plates 107 are arranged at intervals along the length and width directions of the bearing box body 1 to form a plurality of water collection areas 108 for preventing water entering the bearing box body 1 from spreading; the partition plates 107 arranged along the length direction of the bearing box body 1 are all provided with connecting holes 109 at the bottom to make the water collection areas 108 in the length direction connected to each other; the water entering each water collection area 108 can flow from the connecting holes 109 to the drainage port 110 for discharge.

[0050] The cause of seal failure may be due to aging and fracture of the elastic seal 113, or elastic failure after repeated pressure, which makes it unable to return to its original state, resulting in seal failure when pressure is applied again. After failure, water will enter the bearing box body 1. If the seal failure is not discovered in time, more and more water will accumulate in the bearing box body 1. At this time, even with the installation of the guide rod 410, the water will eventually submerge the sliding seat 401 and the movable bearing seat 402, causing some negative effects.

[0051] The water collection area 108 formed by the partition plate 107 at the bottom of the bearing housing body 1 temporarily accumulates incoming water. When water flows in through the working port 106, it flows into the corresponding water collection area 108 and is discharged from the drain port 110 under the guidance of the connecting hole 109. The partition plate 107 prevents the spread of incoming water. The water collection areas 108 along the length of the bearing housing body 1 are interconnected to guide water out and prevent it from accumulating in the bearing housing body 1. The lack of connection across the width of the bearing housing body 1 prevents water entering one water collection area 108 from spreading to other water collection areas 108, thereby maintaining a dry environment in other areas.

[0052] If there is no partition plate 107, when water enters the bearing box body 1, it will spread to the bottom of the bearing box body 1 and wet the entire bottom of the bearing box body 1. Even if the amount of water entering is small, it will still spread and wet the bottom of the bearing box body 1; after the partition plate 107 is set, the water that enters falls into the corresponding water collection interval 108, and can flow through the various water collection intervals 108 connected in the length direction of the bearing box body 1 and be discharged from the drain outlet 110. The drain outlet 110 can be set in the middle of the bottom surface of the bearing box body 1 or near the working port 106, thereby further shortening the water flow path and ensuring the dryness of other positions at the bottom of the bearing box body 1; even if the amount of water entering is large, the partition plate 107 can also block and divert the water, and the connecting hole 109 will guide and drain the water flowing into the corresponding water collection interval 108 in time, so that it will not flow into the water collection interval 108 at other positions, so that the bearing box body 1 can maintain a relatively dry environment as much as possible.

[0053] The bottom of the bearing box body 1 is fittedly connected to the top surface of the crossbeam 2 to prevent water from entering the interior of the bearing box body 1 from the bottom of the bearing box body 1. A drain pipe is provided on the crossbeam 2 at a position corresponding to the drain port 110 for draining water entering the bearing box body 1.

[0054] Since the bottom of the bearing box body 1 is closely connected to the crossbeam 2, it can effectively prevent splashing water from entering the bearing box body 1 through the drain port 110 during working. At this time, if the seal of the extended movable bearing seat 402 and the working port 106 fails, the water entering can be discharged from the drain port 110 and further discharged through the drain pipe provided on the crossbeam 2 to prevent water from accumulating more and more in the bearing box body 1.

[0055] Before the brushing is prepared, the upper half of the rear side of the sliding seat 401 is retracted to form an installation interval, and an encoder 407 is provided in the installation interval so that the bearing box body 1 can provide waterproof protection for the encoder 407. The connection end of the encoder 407 passes through the side wall of the sliding seat 401 and is connected to the center position of the end of the inner core tube 405, so that the encoder 407 can simultaneously monitor the operation of the brush roller 5 and the drive motor 6; this installation interval can prevent the encoder 407 from touching the rear side wall of the bearing box body 1 when the sliding seat 401 slides toward the rear side wall of the bearing box body 1, and an encoder mounting seat 408 for supporting the encoder 407 is connected to the rear side wall of the sliding seat 401.

[0056] Usually, the steel plates to be brushed are relatively long, so the brush roller 5 needs to be in a state of continuous working. However, during production, the brush roller 5 may be separated from the fixed bearing seat 3 or the mobile bearing seat 402. At this time, the brush roller 5 is no longer brushing the steel plate. However, it is impossible to manually observe whether the brush roller 5 is running during the brushing process. Therefore, an encoder 407 is usually provided for monitoring.

[0057] In the traditional method, the encoder 407 is installed on the drive motor 6, and the operating status of the brush roller 5 is deduced by monitoring whether the drive motor 6 is running and the speed. However, the problem is that if the brush roller 5 still detaches at this time, the drive motor 6 will not stop running and will idle, but the situation monitored by the encoder 407 is still in a normal operating state; only when the drive motor 6 fails and stops running, can the encoder 407 detect that it is in an abnormal state and then send a signal.

[0058] In this embodiment, the encoder 407 is connected to the inner core tube 405. If the brush roller 5 is detached at this time, the brush roller 5 is definitely in a non-working state, and the encoder 407 can monitor the occurrence of such a situation. If the brush roller 5 stops rotating due to a failure of the drive motor 6, the encoder 407 can also monitor the abnormal situation and send a signal. Moreover, in the traditional method, the encoder 407 is in an exposed state, while in this embodiment, it is located inside the bearing box body 1, which is not only waterproof but also collision-proof. The setting of the installation interval provides the space required for the connection of the encoder 407, and also ensures that the encoder 407 will not touch the inner wall of the bearing box body 1 when the sliding seat 401 slides to the rear side; on the other hand, it also reduces the weight of the sliding seat 401.

[0059] The above-mentioned encoder mounting seat 408 is a cylindrical structure and is horizontally connected to the rear side of the sliding seat 401 along the length direction of the bearing box body 1. The encoder 407 is fixedly connected to the side wall of the encoder mounting seat 408, and its connecting end extends axially toward the encoder mounting seat 408 through the rear side wall of the sliding seat 401 and is connected to the inner core tube 405.

[0060] The top surface and side walls of the bearing box body 1 are both provided with inspection openings, and an inspection cover plate 116 is detachably connected to the inspection opening by bolts. The side of the inspection cover plate 116 that is attached to the bearing box body 1 is coated with sealant.

[0061] Any equipment may be damaged and need repair and maintenance under continuous operation. The setting of the inspection port makes it convenient for operators to inspect the components inside the bearing box body 1. The applied sealant is to prevent water splashed during the grinding process from entering the interior through the gap between the inspection cover 116 and the bearing box body 1.
