Description

Technical Field

[0001] The invention relates to the technical field of roller bearings, in particular to a high-strength and low-friction torque tapered roller bearing. Background Art

[0002] Tapered roller bearings are an important basic mechanical component. Tapered roller bearings are separable bearings. The inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and unidirectional axial loads. When the bearing is subjected to radial loads, an axial force component will be generated, so another bearing that can withstand the axial force in the opposite direction is required to balance it.

[0003] At present, the roller bearings in the prior art are mostly of one-piece design. During the application process, the outer ring of the bearing is sleeved on the outer surface of the roller. Its unique conical shape fits each other during the application. Although it has a certain connection stability, it is obviously impossible to repair and replace a roller if it is damaged during the specific application process, which may cause the whole roller to be scrapped, poor reliability, and high cost of replacing the bearing as a whole;

[0004] For example, the Chinese patent with the announcement number "CN218935018U" discloses a new double-row tapered roller bearing, including a tapered roller bearing inner sleeve, a tapered rolling groove, a bearing retainer, a restraining shaft, a roller, a retainer slit, a threaded groove, a fixing plate, a small fixing bolt and a double-row tapered roller bearing outer sleeve. By setting a detachable and fixed retainer, it is convenient to inspect and repair the body and improve reliability.

[0005] The above device can indeed realize the function of disassembly and assembly to a certain extent. However, it has some obvious defects and shortcomings in practical application. Specifically, the device adopts a design method in which each screw corresponds to one roller, which means that when a roller is damaged, it is often not just one roller that is damaged. In actual use, it is very likely that multiple rollers will be damaged inside the bearing. At this time, due to the small size of the thread groove and the screw, the disassembly and assembly of multiple rollers requires the cumbersome removal of each screw, which will undoubtedly consume a lot of time and energy, making it difficult to achieve rapid disassembly and replacement when multiple rollers are worn. Obviously, this design is difficult to meet the needs of rapid replacement of rollers. In addition, the rollers are installed with smaller screws, which will bring great risks during high-speed rotation. Since the screws are small , the stress it bears is relatively large. Under long-term high-speed rotation, the screws are very likely to wear or even break. Once there is a problem with the screws, it will not only affect the normal operation of the bearing, but may also cause serious damage to the entire equipment. Moreover, smaller screws are difficult to maintain a strong positioning stability for the roller. During the operation of the equipment, the roller needs to maintain a stable position to ensure the normal operation of the bearing. However, due to the small size of the screws, their ability to position the rollers is limited, which can easily cause the rollers to move and shake during operation, thereby affecting the performance and life of the bearings. In summary, the device has obvious problems in the disassembly and assembly of the rollers and the positioning stability, and has certain defects and deficiencies in overall use. Therefore, it is urgent to improve it to improve its reliability and efficiency in practical applications. Summary of the invention

[0011] Furthermore, the overall cross-sectional shape of the guide block is also arranged in a right triangle, and the inclined surface of the guide block and the inclined surface of the limit block are fitted and connected.

[0012] Furthermore, an adjusting screw is threadedly connected to one side of the adjusting disk, and the end of the adjusting screw is rotatably connected to an outer end of the base disk. The outer end of the adjusting screw passes through the base disk and is fixedly connected to a countersunk hexagonal screw head.

[0013] Furthermore, a protective shell is fixedly installed on the outer side of the base plate, and the protective shell covers the outer sides of the adjusting plate, the connecting rod and the threaded rod.

[0014] Furthermore, mounting plates are fixedly mounted on the outer side of the protective shell in a circular arrangement at equal intervals, and threaded mounting holes are provided on the inner side of the mounting plates.

[0015] Furthermore, the guide mechanism includes an arc-shaped circular groove, which is arranged in a ring shape with equal intervals and opened on the inner inclined surface of the base plate.

After the base plate is installed, the limit block contacts the limit groove, the limit spring resets and pushes the base plate outward, the limit block is inserted into the limit groove, and the auxiliary base plate is clamped at both ends of the base frame. This design not only ensures the stability of the installation, but also provides convenience for subsequent disassembly, which fully reflects the ingenuity and practicality of the design.

[0021] Thirdly, in the present invention, if disassembly is required during use, insert the Allen wrench into the countersunk hexagonal screw head, swing the wrench to drive the adjusting screw to rotate, push the adjusting disk to slide, and the connecting rod assists in supporting the adjusting disk to make it stably retractable.

DETAILED DESCRIPTION

[0031] See also Figure 1-Figure 8 In an embodiment of the present invention, a high-strength and low-friction torque tapered roller bearing comprises a mounting mechanism 1 and two base plates 4, the two base plates 4 are arranged on both sides of the mounting mechanism 1, the inner sides of the base plates 4 are provided with guide mechanisms 3 at equal intervals, the overall cross-sectional shape of the base plates 4 is arranged in an isosceles trapezoidal shape, and the inner sides of the base plates 4 are rotatably connected with a bearing housing 2;

[0032] The mounting mechanism 1 includes a mounting groove 11 and a base frame 12, and reserved grooves 13 are evenly spaced at both ends of the base frame 12. The mounting groove 11 is opened in the middle of the base plate 4, and a limit spring 14 is evenly fixedly installed on the inner side of the reserved groove 13, and a base plate 15 is fixedly installed on the outer end of the limit spring 14. The base plate 15 is slidably connected to the inside of the reserved groove 13, and a limit block 16 is fixedly installed on the outer end of the base plate 15. Limit grooves 17 are evenly spaced on the outer side of the base plate 4, and the inner side of the limit groove 17 is connected to the mounting groove 11. The end of the limit block 16 is inserted into the inside of the limit groove 17, and an adjustment component 18 is movably installed on the outer side of the base plate 4. The mounting mechanism 1 consists of the mounting groove 11 and the base frame 12, and cooperates with the two base plates 4. The overall design is compact and reasonable. The guide mechanism 3 arranged at equal intervals on the side provides a stable guide for the operation of the bearing, ensuring that the roller can accurately move along the predetermined trajectory during rotation, thereby reducing the friction torque. The overall cross-section of the base plate 4 is an isosceles trapezoid. This unique shape design not only has a certain aesthetic appeal in appearance, but more importantly, it has advantages in mechanical properties. The isosceles trapezoidal structure enables the base plate 4 to disperse stress more evenly when subjected to forces from all directions, thereby improving the overall strength and stability of the bearing. The limit system composed of the limit spring 14, the base plate 15 and the limit block 16 arranged in the reserved groove 13 at both ends of the base frame 12 plays a vital role. During the installation process, when the installation groove 11 on the inner side of the base ring contacts the limit blocks at both ends of the base frame 12 16, the limit block 16 is triangular, and its outer inclined surface can fit the inner wall of the installation groove 11 for guidance. At this time, the limit block 16 is forced to squeeze the substrate 15. After the substrate 15 is forced, it acts on the limit spring 14. The limit spring 14 is forced to shrink, causing the limit block 16 to move inward, so that the limit block 16 can completely enter the interior of the installation groove 11. When the base plate 4 is completely installed, the limit block 16 and the limit groove 17 contact each other, and the substrate 15 loses the extrusion force. At this time, the limit spring 14 resets, pushing the substrate 15 to move outward, and the limit block 16 is inserted into the inner side of the limit groove 17. The right-angled side of the limit block 16 and the limit groove 17 contact and limit, which assists in clamping and installing the base plate 4 on the two ends of the base frame 12. This design not only makes the installation process more convenient and efficient, The adjustment assembly 18 movably installed on the outside of the base plate 4 further improves the practicality of the bearing. When disassembly is required, only the Allen wrench needs to be inserted into the countersunk hexagonal screw head 187. The Allen wrench can be swung to drive the countersunk hexagonal screw head 187 to drive the adjusting screw 186 to rotate. After the adjusting screw 186 rotates, the adjusting disk 184 is pushed to slide toward one side of the base plate 4. During this period, the connecting rod slides on the inner side of the sliding hole 181, which can assist in supporting and reinforcing the adjusting disk 184, so that the adjusting disk 184 can stably telescope and slide. As the adjusting disk 184 approaches the base plate 4, the inclined surface of the guide block 185 squeezes the inclined surface of the limit block 16.By squeezing the inclined surface of the limit block 16 with the inclined surface of the guide block 185, the limit block 16 can be pushed inward to disengage from the limit groove 17. At this time, the base plate 4 can be removed from both ends of the base frame 12, and the rollers inside each arc-shaped circular groove 31 can be quickly replaced. This convenient disassembly method saves time and cost for repairing and replacing rollers, and improves the maintainability of the bearing. It can be seen that this high-strength and low-friction torque tapered roller bearing installation mechanism 1 has excellent performance in improving bearing strength, reducing friction torque, facilitating installation and disassembly, and improving maintainability through its ingenious structural design and practical functional configuration, and has extremely high application value.

[0033] See also Figure 1-Figure 7 The overall cross-sectional shape of the base frame 12 and the overall cross-sectional shape of the inner side of the mounting groove 11 are both hexagonal snowflake-shaped, and the overall cross-sectional shape of the limit block 16 is a right-angled triangle. The hexagonal snowflake design of the base frame 12 and the mounting groove 11 performs well in structural stability. Compared with the traditional simple geometric shape, this shape has more edges and angles, and can better disperse forces from all directions. During the operation of the bearing, it will bear loads in different directions. The hexagonal snowflake design enables the base frame 12 and the mounting groove 11 to bear these forces more evenly, thereby improving the stability and strength of the entire bearing structure. At the same time, this unique shape also increases the contact area between the base frame 12 and the mounting groove 11, making the two fit more closely during assembly, reducing possible looseness and clearance, and further enhancing the overall performance of the bearing. The right-angled triangle cross-sectional shape design of the limit block 16 plays an important role in the installation and disassembly process. During installation, when the mounting groove 11 on the inner side of the base ring When the limit blocks 16 at both ends of the base frame 12 are in contact, the outer inclined surface of the limit block 16 can fit the inner wall of the installation groove 11 for guidance. This inclined surface design makes the installation process smoother, and the limit block 16 can smoothly enter the installation groove 11 without precise alignment operation. When the limit block 16 is pressed by the base plate 15, the right-angled triangle shape enables the limit block 16 to slide stably in the reserved groove 13, and when the force is applied, the force can be effectively transmitted to the base plate 15 and the limit spring 1 4. After the base plate 4 is completely installed, the limit block 16 is inserted into the inner side of the limit groove 17. At this time, the right-angled side contacts and limits the limit groove 17. The design of the right-angled side can provide a stable clamping effect, ensuring that the base plate 4 will not easily separate from the base frame 12 during use. When disassembly is required, the shape of the right-angled triangle also enables the inclined surface of the guide block 185 to more effectively squeeze the inclined surface of the limit block 16, thereby pushing the limit block 16 to move inward and separate from the limit groove 17, making the disassembly operation convenient and quick.

[0034] See also Figure 1-Figure 4 and Figure 6The adjusting assembly 18 includes a sliding hole 181 and a limiting ring 182. The sliding holes 181 are arranged in a ring shape with equal intervals and are opened on the outer side of the base plate 4. The interior of the sliding hole 181 is slidably connected with a connecting rod 183. The outer end of the connecting rod 183 is fixedly installed with an adjusting disk 184. The side of the adjusting disk 184 close to the base plate 4 is fixedly connected with a guide block 185 at equal intervals. The overall cross-sectional shape of the guide block 185 is also set in a right-angled triangle. The inclined surface of the guide block 185 is fitted and connected with the inclined surface of the limiting block 16. One side of the adjusting disk 184 is threadedly connected with an adjusting screw 186. The end of the adjusting screw 186 is rotatably connected to one end of the outer side of the base plate 4. The outer end of the adjusting screw 186 passes through the base plate 4 and is fixedly connected with a countersunk hexagonal screw head 187. The sliding holes 181 are arranged in a ring shape with equal intervals. The row is opened on the outside of the base plate 4, providing a stable sliding channel for the connecting rod 183. The sliding connection design of the connecting rod 183 in the sliding hole 181 enables the adjusting disk 184 to be effectively supported and guided during the movement. When the disassembly operation is required, this structure can ensure that the adjusting disk 184 slides smoothly toward the side of the base plate 4 without shaking or offsetting, thereby ensuring the accuracy and reliability of the disassembly process. The guide blocks 185 fixedly connected to the adjusting disk 184 at equal intervals on one side of the base plate 4 have an overall cross-sectional shape of a right triangle, which is fitted and connected to the inclined surface of the limit block 16. This design plays a key role in the disassembly and installation process. During disassembly, the adjusting disk 184 is pushed closer to the base plate 4 by rotating the adjusting screw 186. At this time, the inclined surface of the guide block 185 squeezes the inclined surface of the limit block 16, and the interaction of the triangular inclined surfaces can effectively push the limit block 16 inward to disengage it from the limit groove 17, thereby realizing the rapid disassembly of the base plate 4. During the installation process, the adjusting screw 186 is operated in the reverse direction to make the adjusting disk 184 away from the base plate 4, providing space for the reset of the limit block 16 and facilitating the installation of the base plate 4. This design makes the disassembly and installation process simple and fast, and improves work efficiency. The threaded connection between the adjusting screw 186 and the adjusting disk 184 and the rotation connection design between its end and the outer end of the base plate 4 provide precise control means for the entire adjustment process. By rotating the countersunk hexagonal screw head 187, the adjusting screw 186 can be easily driven to rotate, thereby accurately The position of the adjusting disk 184 can be accurately controlled. The design of the countersunk hexagonal screw head 187 is convenient for operation with tools, which improves the convenience of operation. At the same time, this threaded connection and rotational connection method can ensure the stability and reliability of the adjustment process, and there will be no loosening or loss of control. It can be seen that the adjustment component 18 of the bearing has a reasonable structural design to achieve fast and accurate disassembly and installation operations, improve the maintainability and ease of use of the bearing, and make an important contribution to the performance improvement of high-strength and low-friction torque tapered roller bearings. The overall cross-sectional shape of the connecting rod 183 is T-shaped, and it and the limit ring 182 can limit each other, which can prevent the connecting rod 183 from falling off, and the overall connection can enable the connecting rod 183 to be stably installed on the outside of the base plate 4.

[0035] See also Figure 1-Figure 2 , Figure 4 and Figure 6 A protective shell 5 is fixedly installed on the outer side of the base plate 4, and the protective shell 5 covers the outer sides of the adjusting disk 184, the connecting rod 183 and the threaded rod. The outer side of the protective shell 5 is evenly spaced and fixedly installed with mounting plates 188 in a circular arrangement. The inner side of the mounting plate 188 is provided with threaded mounting holes 189. The protective shell 5 can play a good protective role for important components such as the adjusting disk 184, the connecting rod 183 and the threaded rod. In the actual use of the bearing, it may face various complex working environments, such as dust, oil, moisture, etc. The protective shell 5 can effectively prevent these external factors from eroding and damaging the internal adjusting component 18, ensuring that the adjusting disk 184, the connecting rod 183 and the threaded rod are always in good working condition, extending the service life of these components, and thus ensuring the overall reliability and stability of the bearing. Secondly The mounting plates 188 fixedly installed in a circular arrangement at equal intervals on the outside of the protective shell 5 and the threaded mounting holes 189 opened on the inner side of the mounting plates 188 provide convenience for the installation of the bearings. Through these threaded mounting holes 189, the bearings can be conveniently connected and fixed with other equipment to ensure that the bearings will not loosen or move during operation. At the same time, this evenly distributed installation method also makes the installation more secure and can better withstand forces from different directions, thereby improving the installation accuracy and stability of the bearings. In addition, the existence of the protective shell 5 also improves the overall aesthetics of the bearing. It effectively shields the complex internal structure, making the bearing more concise and regular in appearance. In some occasions where there are requirements for the appearance of the equipment, this design can better meet the needs of users and enhance the overall image of the equipment.

[0036] See also Figure 3-Figure 4 and Figure 6The guide mechanism 3 includes an arcuate circular groove 31, which is arranged in a ring shape at equal intervals and is opened at the inner inclined surface of the base plate 4. A support rod 32 is fixedly installed on the inner side of the arcuate circular groove 31, and a guide roller 33 is rotatably connected to the outer surface of the support rod 32. A magnetic ring 34 is fixedly connected to the outer end of the inner side of the arcuate circular groove 31. The magnetic ring 34 and the guide roller 33 are magnetically connected. The magnetic ring 34 is set to martensitic stainless steel. The magnetic ring 34 can absorb the guide roller 33 to prevent the guide roller 33 from accidentally falling during installation, which is convenient for quick installation. The bearing housing 2 includes a conical ring 21, which is rotatably connected between the outer sides of the two base plates 4. The inner inclined surface of the conical ring 21 The outer surface of the conical ring 21 is fitted and connected with the surface of the guide roller 33. The outer side of the conical ring 21 is fixedly installed with a shell 22, and the shell 22 covers the outer side of the mounting mechanism 1 and the base plate 4. The outer side of the shell 22 is fixedly installed with a mounting plate 23. The outer side of the mounting plate 23 is provided with countersunk mounting holes 24 at equal intervals. The arc-shaped circular grooves 31 in the guide mechanism 3 are arranged in a ring at equal intervals and are opened on the inner side inclined surface of the base plate 4, providing a stable installation position for the guide roller 33. The support rod 32 on the inner side of the arc-shaped circular groove 31 enables the guide roller 33 to rotate stably on its outer surface. The cooperation between the support rod 32 and the guide roller 33 ensures the movement accuracy and stability of the roller during work, reducing unnecessary The friction and wear of the guide roller 33 are reduced, thereby reducing the friction torque. The magnetic ring 34 at the inner outer end of the arc-shaped circular groove 31 is made of martensitic stainless steel and has strong magnetism. It can be magnetically connected to the guide roller 33 and can effectively adsorb the guide roller 33 during installation to avoid the guide roller 33 from accidentally falling off, which greatly facilitates quick installation. This design improves the installation efficiency and reduces the occurrence of unexpected situations during the installation process. The conical ring 21 in the bearing housing 2 is rotatably connected between the outer sides of the two base plates 4, and its inner inclined surface is fitted and connected to the surface of the guide roller 33. When the bearing is working, the cooperation between the conical ring 21 and the guide roller 33 can achieve smoother rotation. The conical ring 21 plays a certain role in limiting and guiding the guide roller 33, ensuring that the roller moves on the correct track, improving the working accuracy and stability of the bearing, and the shell 22 on the outside of the conical ring 21 covers the outside of the mounting mechanism 1 and the base plate 4, which plays a good protective role for the entire bearing structure and can effectively prevent external dust, impurities, etc. from entering the bearing and affecting the normal operation of the bearing. The mounting plate 23 on the outside of the shell 22 and the countersunk mounting holes 24 arranged at equal intervals provide convenience for the connection between the bearing and other equipment, making the installation more firm and reliable, and can better adapt to different installation requirements.

[0037] The working principle of the present invention is as follows: in the present invention, during the actual application of the device, by setting the bearing housing 2 and the guide mechanism 3 to cooperate with each other, the guide roller 33 can be sleeved on the outer surface of the support rod 32 during use. At this time, the magnetic ring 34 exerts a strong adsorption effect, which can firmly adsorb the guide roller 33, ensuring that the guide roller 33 is stably located in the arc-shaped circular groove 31 and will not fall off easily, which greatly facilitates the installation operation. After the guide roller 33 is installed, the conical ring 21 is placed on the top of a base plate 4, and the bottom inclined surface of the conical ring 21 is tightly connected to the outer surface of the guide roller 33. Then, the base frame 12 is inserted into the installation groove 11, and then another base plate 4 is covered on the top of the base frame 12. When the two base plates 4 are assembled and installed, the limit block 16 is just located at the limit The inner side of the groove 17 can assist in the clamping and installation of the two base plates 4. At the same time, when the base plates 4 are clamped and installed, the bearing housing 2 can be stably sleeved between the outer sides of the base plates 4, thereby completing the entire stable installation process. During the application process, the countersunk mounting hole 24 and the threaded mounting hole 189 are respectively connected to the required application device. During the rotation, the guide roller 33 plays an auxiliary rolling guide role between the tapered ring and the inner side of the base plate 4. Since the guide roller 33 is sleeved on the outer surface of the support rod 32, and the guide roller 33 rotates on the inner side of the arc-shaped circular groove 31, the arc-shaped inner wall of the support rod 32 and the arc-shaped circular groove 31 can assist in support and reinforcement, thereby promoting the overall stability of the guide roller 33, further improving the stability of the guide roller 33 during the overall use period, and extending its service life;

[0038] In the present invention, during the installation of the bearing, when the mounting groove 11 on the inner side of the base ring contacts the limit blocks 16 at both ends of the base frame 12, the limit blocks 16 are triangular, and the outer inclined surface of the limit blocks 16 can fit the inner wall of the mounting groove 11 for guidance. At this time, the limit blocks 16 are forced to squeeze the base plate 15, and the base plate 15 is forced to act on the limit spring 14, and the limit spring 14 is forced to contract. In this way, the limit blocks 16 can be moved inward, so that the limit blocks 16 can completely enter the inner wall of the mounting groove 11. When the base plate 4 is completely installed, the limit block 16 and the limit groove 17 contact each other, and the base plate 15 loses the extrusion force. At this time, the limit spring 14 is reset, pushing the base plate 15 outward, and the limit block 16 is inserted into the inner side of the limit groove 17. The right-angle side of the limit block 16 and the limit groove 17 contact and limit, which assists in clamping and installing the base plate 4 on both ends of the base frame 12. During use, if it is necessary to disassemble, just insert the Allen wrench into the countersunk hexagonal screw head 187, and swing the Allen wrench to drive The countersunk hexagonal screw head 187 drives the adjusting screw 186 to rotate. After the adjusting screw 186 rotates, the adjusting disk 184 is pushed to slide toward the side of the base plate 4. During this period, the connecting rod slides on the inner side of the sliding hole 181, which can assist in supporting and reinforcing the adjusting disk 184, so that the adjusting disk 184 can be stably telescopically slidable. As the adjusting disk 184 approaches the base plate 4, the inclined surface of the guide block 185 squeezes the inclined surface of the limit block 16, and the inclined surface of the guide block 185 squeezes the inclined surface of the limit block 16, so that the adjusting disk 184 can be pushed. The limit block 16 moves inward and disengages from the limit groove 17. At this time, the base plate 4 can be removed from both ends of the base frame 12. It can be seen that during the disassembly and assembly of the device, only one adjusting screw 186 needs to be adjusted to synchronously link all the limit blocks 16, so that the base plate 4 can be quickly removed. At this time, the rollers inside each arc-shaped circular groove 31 can be quickly replaced as needed. It can be seen that the overall disassembly, assembly and maintenance of the device are relatively fast and convenient, and the overall use and operation are more convenient, making the overall device extremely valuable for promotion and application.
