Description

Technical Field

[0001] This application relates to the technical field of pulley bearing housing and shaft modification, and in particular to a guide bar pulley bearing housing and shaft. Background Technology

[0002] The guide rail pulley bearing housing and shaft are the core transmission components of guide rail equipment in industries such as textiles, printing and dyeing, and papermaking. Their performance directly affects the operational stability, production efficiency, and maintenance costs of the equipment.

[0003] Traditional bearing housings and bearing structures have unreasonable design flaws that are not conducive to uniform force transmission. This causes stress to concentrate in local areas when the bearing is under load and cannot be effectively dispersed, causing the bearing to bear additional unbalanced forces. In cases where the type and specifications of the selected bearing and bearing housing are not matched, the load-bearing capacity cannot meet the working load-bearing capacity.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a guide bar pulley bearing housing and shaft, which has the advantages of improving production efficiency and reducing equipment failure rate. It solves the problem that the existing device is not conducive to uniform force transmission, which leads to stress concentration in local areas when bearing load, and cannot be effectively distributed, causing the bearing to bear additional unbalanced force. In the case of mismatch between the selected bearing and bearing housing type and specifications, the load-bearing capacity cannot meet the working load-bearing capacity.

[0006] The technical solution provided in this application for a guide bar frame pulley bearing seat and shaft is as follows: It includes a connecting shaft, with two fixed shafts fixedly connected to its outer surface. Each fixed shaft has a bearing body fixedly mounted on its outer surface. A spacer is fixedly connected to the outer surface of the connecting shaft, and the outer surface of the spacer is fixedly connected to both fixed shafts. A bearing frame and a cover are provided on the outer side of the connecting shaft. The inner wall of the cover is slidably connected to the bearing frame. Both the bearing frame and the inner wall of the cover are rotatably connected to their respective fixed shafts. The inner wall of the bearing frame is inserted into both bearing bodies. Several sliding grooves are formed on the outer surface of the bearing frame. Several limiting plates are fixedly connected to the inner wall of the cover, and the inner wall of each sliding groove is slidably connected to its corresponding limiting plate.

[0007] By adopting the above technical solution, the connecting shaft serves as the central load-bearing component of the overall structure. Two fixed shafts are fixedly connected to its outer surface, forming a symmetrical support structure. Simultaneously, the two fixed shafts are connected by spacers, enhancing overall rigidity and preventing deformation of the fixed shafts under stress. The bearing housing is installed on the outer surface of the corresponding fixed shaft to reduce rotational friction between the fixed shaft and external components, improving rotational smoothness. The bearing bracket and cover form a combined protective structure, together forming a bearing seat to support the connecting shaft. The inner wall of the cover is slidably connected to the bearing bracket, allowing for relative opening and closing, facilitating the installation and maintenance of internal components. The inner walls of both the bearing bracket and cover are rotatably connected to the corresponding fixed shaft, ensuring the overall structure can rotate flexibly around the fixed shaft. Simultaneously, the inner wall of the bearing bracket is inserted into the two bearing bodies, further fixing their positions and preventing displacement. The sliding engagement of the slide groove and the limiting plate restricts the relative movement trajectory of the bearing bracket and cover, ensuring they can only slide smoothly along the slide groove direction, preventing misalignment or detachment, and improving structural stability.

[0008] Preferably, the outer surface of the cover is provided with a plurality of first fixing grooves, and the outer surface of the bearing frame is provided with a plurality of second fixing grooves, wherein the inner wall of each first fixing groove is connected to the corresponding second fixing groove.

[0009] By adopting the above technical solution, the first fixing groove is opened on the outer surface of the frame cover, and the number corresponds to the second fixing groove. It is a fixing interface on one side of the frame cover. When the frame cover and the bearing frame slide to close to the preset position, the inner wall of each first fixing groove is connected to the corresponding second fixing groove to form a complete fixing channel. The core function of this structure is to provide installation space for external fasteners.

[0010] Preferably, a fixing bolt is inserted into the inner wall of each of the first fixing slots, and the outer surface of each fixing bolt is inserted into the corresponding second fixing slot.

[0011] By adopting the above technical solution, the fixing bolt, as the core fastener, is inserted into the first fixing groove of the cover, passes through the entire groove, and then extends into the second fixing groove of the bearing bracket, forming an insertion fit with the groove. The cooperation between the sliding groove and the limiting plate can ensure the precise position of the cover and the bearing bracket when closed, so that the first fixing groove and the corresponding second fixing groove are perfectly aligned. Then, the fixing bolt locks the two through the aligned fixing grooves, preventing relative sliding or separation. This ensures convenience during installation and maintenance, and provides a reliable fastening effect during equipment operation.

[0012] Preferably, the inner wall of each of the second fixing grooves is fixedly connected to a placement groove, the inner wall of each placement groove is inserted with a fixing nut, and the inner wall of each fixing nut is threadedly connected to a corresponding fixing bolt.

[0013] By adopting the above technical solution, the rigid locking of the fixing bolt is achieved through the cooperation of the placement groove and the fixing nut, which further improves the connection structure between the bearing bracket and the bracket cover. The placement groove is opened on the bearing bracket and is fixedly connected to the inner wall of the second fixing groove. Its size matches the fixing nut and is specially used to accommodate and position the fixing nut to prevent the fixing nut from rotating or shifting during installation or operation. The fixing nut is inserted into the placement groove, and the inner wall is threadedly connected to the corresponding fixing bolt. Through the thread engagement of the fixing bolt and the fixing nut, the bracket cover and the bearing bracket are firmly locked to form a stable rigid connection.

[0014] Preferably, the outer surface of the connecting shaft has two mounting grooves, and a fixing block is engaged with the inner wall of each mounting groove.

[0015] By adopting the above technical solution, two mounting slots are opened on the outer surface of the connecting shaft. Their shape and size match the fixing block, serving as the mounting base for the fixing block and providing precise positioning space. The fixing block is assembled in the mounting slot by snap-fit, forming a rigid connection with the connecting shaft.

[0016] Preferably, the outer side of the connecting shaft is provided with two transmission wheels, and the inner wall of each transmission wheel is provided with a connecting groove.

[0017] By adopting the above technical solution, the transmission wheel is set on the outside of the connecting shaft and is the core component for realizing power transmission. The connecting groove is opened on the inner wall of each transmission wheel, and its shape and size are matched with the corresponding fixed block. It is the key interface for the transmission wheel to form a connection with the connecting shaft. The rotation of the connecting shaft will drive the transmission wheel to rotate.

[0018] Preferably, the inner wall of each of the transmission wheels is slidably connected to the connecting shaft, and the inner wall of each of the connecting grooves is slidably connected to the corresponding fixing block.

[0019] By adopting the above technical solution, the fixing block is snapped into the mounting groove of the connecting shaft, and its position is fixed. The connecting groove slides along the fixing block, which restricts the movement trajectory of the transmission wheel and ensures that it can only slide smoothly along the axial direction of the connecting shaft, avoiding circumferential rotation or offset. During installation or maintenance, the position of the transmission wheel can be finely adjusted by sliding to ensure precise alignment with external transmission components and reduce uneven wear or vibration during operation.

[0020] Preferably, the inner wall of the bearing frame is provided with a drainage groove, and a fixing cover is inserted into the inner wall of the drainage groove.

[0021] By adopting the above technical solution, the drainage channel is opened on the inner wall of the bearing bracket. It is a channel with a specific direction. Its core function is to guide the lubricating oil and grease to flow inside the bearing bracket and accurately deliver them to the key parts that need lubrication or cooling. The fixed cover is inserted into the inner wall of the drainage channel, which can form a closed or semi-closed state for the drainage channel, preventing external dust and impurities from entering the bearing bracket through the drainage channel.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This guide bar frame pulley bearing housing and shaft, by setting up components such as a fixed shaft, connecting shaft, spacer column, support frame, frame cover, limiting plate, and slide groove, increases the number of bearings and widens the bearings and bearing housing by increasing the number of bearings and the spacer column. After long-term operation, the equipment stabilizes significantly, improves production efficiency, and effectively reduces the equipment failure rate. The sliding cooperation of the limiting plate and slide groove restricts the relative movement trajectory of the frame cover and bearing frame, preventing misalignment or detachment during opening, closing, or operation, thus improving the safety of operation. In this way, the device can expand the bearing area by increasing the number and width of bearings, so that the load-bearing force can be more evenly distributed on the bearings and bearing housing.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A guide bar frame pulley bearing housing and shaft, refer to Figure 1 , Figure 3 , Figure 4 The structure includes a connecting shaft 1, with two fixed shafts 2 fixedly connected to its outer surface. Each fixed shaft 2 has a bearing body 3 fixedly mounted on its outer surface. A spacer 19 is fixedly connected to the outer surface of the connecting shaft 1, with the outer surface of the spacer 19 also fixedly connected to both fixed shafts 2. A bearing bracket 4 and a cover 5 are provided on the outer side of the connecting shaft 1. The inner wall of the cover 5 is slidably connected to the bearing bracket 4. The inner walls of both the bearing bracket 4 and the cover 5 are rotatably connected to their respective fixed shafts 2. The inner wall of the bearing bracket 4 is inserted into both bearing bodies 3. Several grooves 7 are formed on the outer surface of the bearing bracket 4. Several limiting plates 6 are fixedly connected to the inner wall of the cover 5, with the inner wall of each groove 7 slidably connected to its corresponding limiting plate 6. The connecting shaft 1 serves as the central load-bearing component of the overall structure, with two fixed shafts 2 fixedly connected to its outer surface, forming a symmetrical support structure. Simultaneously, the two fixed shafts 2 are connected via the spacer 19. Shaft 2 enhances overall rigidity and prevents deformation under stress. Bearing body 3 is installed on the outer surface of the corresponding fixed shaft 2 to reduce rotational friction between the fixed shaft 2 and external components, improving rotational smoothness. Bearing bracket 4 and bracket cover 5 form a combined protective structure, which together form a bearing seat to support the connecting shaft 1. The inner wall of bracket cover 5 is slidably connected to bearing bracket 4 and can be opened and closed relative to each other, facilitating the installation and maintenance of internal components. The inner walls of bearing bracket 4 and bracket cover 5 are rotatably connected to the corresponding fixed shaft 2, ensuring that the overall structure can rotate flexibly around the fixed shaft 2. At the same time, the inner wall of bearing bracket 4 is inserted into two bearing bodies 3 to further fix the position of bearing bodies 3 and prevent them from shifting. The sliding cooperation between slide groove 7 and limit plate 6 restricts the relative movement trajectory of bearing bracket 4 and bracket cover 5, ensuring that they can only slide smoothly along the direction of slide groove 7, avoiding misalignment or detachment, and improving structural stability.

[0033] Example 2: A guide bar bracket pulley bearing housing and shaft, please refer to... Figure 3 , Figure 4 The outer surface of the cover 5 is provided with several first fixing grooves 8, and the outer surface of the bearing frame 4 is provided with several second fixing grooves 9. The inner wall of each first fixing groove 8 is connected to the corresponding second fixing groove 9. The first fixing grooves 8 are opened on the outer surface of the cover 5, and their number corresponds to the number of the second fixing grooves 9. They are the fixing interfaces on one side of the cover 5. When the cover 5 and the bearing frame 4 slide to close to the preset position, the inner wall of each first fixing groove 8 is connected to the corresponding second fixing groove 9 to form a complete fixing channel. The core function of this structure is to provide installation space for external fasteners.

[0034] Please see Figure 1 , Figure 2 , Figure 3Each first fixing groove 8 has a fixing bolt 11 inserted into its inner wall. The outer surface of each fixing bolt 11 is inserted into the corresponding second fixing groove 9. The fixing bolt 11 is the core fastener. It is inserted from the first fixing groove 8 of the cover 5, passes through the entire groove, and then extends into the second fixing groove 9 of the bearing frame 4, forming an insertion fit with the groove. The mutual cooperation of the sliding groove 7 and the limiting plate 6 can ensure that the cover 5 and the bearing frame 4 are accurately positioned when closed, so that the first fixing groove 8 and the corresponding second fixing groove 9 are perfectly aligned. Then the fixing bolt 11 locks the two through the aligned fixing grooves to prevent relative sliding or separation. This ensures the convenience of installation and maintenance, and provides a reliable fastening effect during equipment operation.

[0035] Please see Figure 3 , Figure 4 , Figure 5 Each second fixing groove 9 has a fixedly connected placement groove 10 on its inner wall. Each placement groove 10 has a fixing nut 12 inserted into its inner wall. The inner wall of each fixing nut 12 is threadedly connected to the corresponding fixing bolt 11. Through the cooperation of the placement groove 10 and the fixing nut 12, the fixing bolt 11 is rigidly locked, which further improves the connection structure between the bearing bracket 4 and the bracket cover 5. The placement groove 10 is opened on the bearing bracket 4 and is fixedly connected to the inner wall of the second fixing groove 9. Its size matches the fixing nut 12 and is specially used to accommodate and position the fixing nut 12 to prevent the fixing nut 12 from rotating or shifting during installation or operation. The fixing nut 12 is inserted into the placement groove 10 and its inner wall is threadedly connected to the corresponding fixing bolt 11. Through the thread engagement of the fixing bolt 11 and the fixing nut 12, the bracket cover 5 and the bearing bracket 4 are firmly locked to form a stable rigid connection.

[0036] Please see Figure 3 Two mounting slots 13 are formed on the outer surface of the connecting shaft 1. A fixing block 14 is snapped into the inner wall of each mounting slot 13. There are two mounting slots 13 on the outer surface of the connecting shaft 1. Their shape and size match the fixing block 14. They serve as the mounting base for the fixing block 14 and provide precise positioning space. The fixing block 14 is assembled in the mounting slot 13 by snapping and forms a rigid connection with the connecting shaft 1.

[0037] Please see Figure 1 , Figure 2 Two transmission wheels 17 are provided on the outer side of the connecting shaft 1. Each transmission wheel 17 has a connecting groove 18 on its inner wall. The transmission wheel 17 is located on the outer side of the connecting shaft 1 and is the core component for realizing power transmission. The connecting groove 18 is opened on the inner wall of each transmission wheel 17. Its shape and size are matched with the corresponding fixing block 14. It is the key interface for the transmission wheel 17 to form a connection with the connecting shaft 1. The rotation of the connecting shaft 1 will drive the transmission wheel 17 to rotate.

[0038] Please see Figure 2 The inner wall of each transmission wheel 17 is slidably connected to the connecting shaft 1, and the inner wall of each connecting groove 18 is slidably connected to the corresponding fixing block 14. The fixing block 14 is snapped into the mounting groove 13 of the connecting shaft 1 and its position is fixed. The connecting groove 18 slides along the fixing block 14, which restricts the movement trajectory of the transmission wheel 17 and ensures that it can only slide smoothly along the axial direction of the connecting shaft 1, avoiding circumferential rotation or offset. During installation or maintenance, the position of the transmission wheel 17 can be finely adjusted by sliding to ensure precise alignment with the external transmission components and reduce uneven wear or vibration during operation.

[0039] Please see Figure 5 The inner wall of the bearing housing 4 is provided with a drainage groove 15, and a fixed cover 16 is inserted into the inner wall of the drainage groove 15. The drainage groove 15 is a channel with a specific direction, and its core function is to guide the lubricating oil and grease to flow inside the bearing housing 4 and accurately deliver them to the key parts that need lubrication or cooling. The fixed cover 16 is inserted into the inner wall of the drainage groove 15, which can form a closed or semi-closed state of the drainage groove 15 to prevent external dust and impurities from entering the interior of the bearing housing 4 through the drainage groove 15.

[0040] The implementation principle of this application embodiment is as follows: The connecting shaft 1, as the core load-bearing component, forms a rigid integrated structure with the two fixed shafts 2 through the spacer column 19, ensuring that the whole is not easily deformed under force. The bearing body 3 on the outer surface of the fixed shaft 2 converts the relative movement of the bearing frame 4 and the cover 5 with the fixed shaft 2 into low-resistance rotation through rolling friction, reducing component wear and improving smooth operation. By setting two bearing bodies 3, the bearing area is expanded, so that the load can be more evenly distributed on the bearing body 3 and the bearing frame 4. The bearing frame 4 and the cover 5 achieve precise docking through the sliding structure of the sliding groove 7 and the limiting plate 6, which not only limits the relative offset between the two, but also ensures the stability of the opening and closing action. When the two are closed, the bearing frame 4 and the cover 5 together wrap around the bearing body 3. Together with the fixed shaft 2, a closed protective space is formed to prevent the intrusion of external impurities. After the cover 5 and the bearing bracket 4 are closed, the first fixed groove 8 and the second fixed groove 9 are precisely connected. The fixing bolt 11 passes through the two grooves and is threadedly connected to the fixing nut 12 in the placement groove 10, which rigidly fixes the cover 5 and the bearing bracket 4 into one unit, preventing loosening due to vibration or vibration during operation. The drainage groove 15 serves as a preset channel to guide the lubricant to the friction surface between the bearing body 3 and the fixed shaft 2, achieving precise lubrication. The fixed cover 16 seals the drainage groove 15 by inserting it to prevent lubricant leakage or impurities from entering. After removing the fixed cover 16, lubricant can be added directly through the drainage groove 15 or internal dirt can be cleaned without disassembling the bearing bracket 4 and the cover 5, greatly simplifying the maintenance process.
