Description
Technical Field
[0001] The utility model relates to the technical field of bearings, in particular to a double-row steel wire roller bearing. Background Art
[0002] In the industrial field, bearings are key components of mechanical transmission, and their performance and versatility are crucial to the stable operation of equipment.
[0003] Traditional bearing structures are often relatively simple in the design of the connecting shaft ring and the inner shaft ring. The sizes of the connecting shaft ring and the inner shaft ring are usually fixed and matched, which to a certain extent limits the application scenarios and versatility of the bearings. In actual production, different equipment may require shafts of different sizes to be connected to bearings, and existing bearings are difficult to flexibly adapt to shafts of various sizes. When the equipment needs to be upgraded or modified, the original bearings may not meet the new shaft diameter requirements, which requires the replacement of the entire bearing, increasing costs and maintenance difficulties; in addition, in harsh working environments, dust, impurities, etc. can easily enter the bearing, resulting in poor lubrication, further exacerbating bearing wear.
[0004] To this end, we propose a double-row wire roller bearing. Utility Model Content
[0005] The main purpose of the utility model is to provide a double-row wire roller bearing, which can improve the versatility, adaptability, sealing and service life, reduce maintenance costs, ensure stable operation of equipment, and effectively solve the problems in the background technology, in order to prevent the bearing from increasing costs and maintenance difficulties due to the inability to adapt to different shaft diameters, and dust and impurities entering the inside of the bearing, resulting in poor lubrication and increased wear.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A double-row wire roller bearing, comprising an inner shaft ring and an outer shaft ring, wherein the outer shaft ring is arranged outside the inner shaft ring, and two relatively parallel connecting shaft rings are inserted at both ends of the inner side of the inner shaft ring, and the outer top and bottom edges of the two connecting shaft rings are both provided with limit blocks, and the top and bottom ends of both ends of the inner shaft ring are both provided with limit grooves matching the limit blocks;
[0008] A screw hole is formed on the inner wall of one end of the limiting groove, and a threaded through hole is formed on the end of the limiting block close to the screw hole to match the fixing bolt, and one end of the fixing bolt passes through the threaded through hole and is threadedly connected to the screw hole;
[0009] A sealing ring is provided between the inner shaft ring and the outer shaft ring. A refueling port is provided on the upper portion of the sealing ring away from one end. A sealing cover is provided on the inner side of the refueling port. An oil delivery channel connected to the refueling port is provided inside the sealing ring.
[0010] By adopting the above technical solution, the connecting shaft ring is connected to the shaft of the external equipment, driving the inner shaft ring to rotate. The inner shaft ring realizes relative rotation with the outer shaft ring through the double-row steel wire roller. The limit block on the connecting shaft ring cooperates with the limit groove on the inner shaft ring to prevent the connecting shaft ring from axial displacement inside the inner shaft ring. When the connecting shaft ring needs to be installed or removed, the fixing bolt is rotated to pass through the threaded through hole and threadedly connected or separated from the screw hole, thereby achieving the fixing or removal of the connecting shaft ring and the inner shaft ring.
[0011] The sealing ring plays a sealing role to prevent external dust, impurities, etc. from entering the space between the inner shaft ring and the outer shaft ring and affecting the normal operation of the bearing. When the bearing needs to be lubricated, the sealing cover can be opened and lubricating oil can be injected into the oil channel inside the sealing ring through the oil filling port. The lubricating oil flows into the space between the inner shaft ring and the outer shaft ring through the oil channel to lubricate the double-row steel wire roller, reducing friction and wear, and improving the service life and working efficiency of the bearing.
[0012] Furthermore, the oil delivery channel includes a first oil chamber and a second oil chamber.
[0013] By adopting the above technical solution, the lubricating oil first enters the first oil chamber, then flows to the second oil chamber, and finally flows into the space between the inner shaft ring and the outer shaft ring, lubricating the double-row steel wire roller, reducing friction and wear, and improving the service life and working efficiency of the bearing.
[0014] Furthermore, the oil filling port is located at one end of the first oil chamber and is connected to the first oil chamber.
[0015] By adopting the above technical solution, since the oil filling port is located at one end of the first oil chamber and is connected, when the bearing needs to be lubricated, the sealing cover is opened and lubricating oil is injected into the first oil chamber through the oil filling port.
[0016] Furthermore, a through hole is provided between the first oil chamber and the second oil chamber.
[0017] By adopting the above technical solution, after the lubricating oil enters the first oil chamber, since a through hole is provided between the first oil chamber and the second oil chamber, the lubricating oil will flow to the second oil chamber through the through hole.
[0018] Furthermore, an oil outlet is formed at one end of the second oil chamber away from the first oil chamber.
[0019] By adopting the above technical solution, the lubricating oil flows out from the oil outlet opened at one end of the second oil chamber.
[0020] Furthermore, the oil outlets and through holes are arranged in a ring array in multiple groups and are staggered with each other.
[0021] By adopting the above technical solution, this staggered arrangement can make the lubricating oil more evenly distributed to the space between the inner shaft ring and the outer shaft ring, comprehensively lubricate the double-row steel wire roller, reduce the friction and wear between the double-row steel wire roller and the inner shaft ring and the outer shaft ring, and improve the service life and working efficiency of the bearing.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] (1) The utility model relates to a double-row steel wire roller bearing, wherein the diameter of the connecting shaft ring is smaller than that of the inner shaft ring. This design enables the bearing to adapt to shafts of different diameters when connected. When the shaft diameter in the equipment changes, there is no need to replace the entire bearing, and only the appropriate connecting shaft ring needs to be selected. This greatly improves the versatility of the bearing and reduces the cost of equipment upgrades or modifications. Since it can adapt to shafts of different sizes, the double-row steel wire roller bearing can be widely used in various types of mechanical equipment, whether small or large equipment, as long as the shaft diameter is within a certain range, the bearing can be used, thus broadening the application range of the bearing.
[0024] (2) The utility model provides a double-row wire roller bearing. Although the diameter of the connecting shaft ring is smaller than that of the inner shaft ring, the stability of the connection can still be ensured through the cooperation of the limit block and the limit groove and the fixation of the fixing bolts. During the operation of the equipment, the connecting shaft ring can be firmly connected to the inner shaft ring without loosening or offset, thereby ensuring the transmission accuracy and reliability of the shaft. The connecting shaft ring with a smaller diameter is more convenient to install and disassemble, and the operator can more easily insert the connecting shaft ring into the inner shaft ring or remove it from the inner shaft ring; at the same time, the operation of the fixing bolts is also more convenient, thereby improving the efficiency of installation and maintenance.
[0025] (3) The utility model relates to a double-row steel wire roller bearing, in which an oil delivery channel is provided inside the sealing ring, including a first oil chamber, a second oil chamber, and a through hole and an oil outlet therebetween, and the oil outlet and the through hole annular array are provided in multiple groups and are staggered with each other. This design enables the lubricating oil to be more evenly distributed to the space between the inner shaft ring and the outer shaft ring, thereby fully lubricating the double-row steel wire roller, effectively reducing the friction and wear between the rolling elements and the inner shaft ring and the outer shaft ring, and improving the service life and working efficiency of the bearing.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0031] In order to prevent the problems of bearings not being able to adapt to different shaft diameters, which increase costs and maintenance difficulties, and dust and impurities entering the bearings, which lead to poor lubrication and increased wear, the versatility, adaptability, sealing and service life can be improved, maintenance costs can be reduced, and stable operation of the equipment can be guaranteed. Figure 1 、 Figure 2 、 Figure 3 As shown, a double-row wire roller bearing comprises an inner shaft ring 1 and an outer shaft ring 2. The outer shaft ring 2 is arranged outside the inner shaft ring 1. Two relatively parallel connecting shaft rings 3 are inserted at both ends of the inner side of the inner shaft ring 1. The outer top and bottom edges of the two connecting shaft rings 3 are both provided with limit blocks 4. The top and bottom ends of both ends of the inner shaft ring 1 are both provided with limit grooves 5 that match the limit blocks 4.
[0032] A screw hole 7 is formed on the inner wall of one end of the limiting groove 5, and a threaded through hole 6 is formed on the end of the limiting block 4 near the screw hole 7 to be connected with a fixing bolt 8. One end of the fixing bolt 8 passes through the threaded through hole 6 and is threadedly connected with the screw hole 7.
[0033] A sealing ring 9 is provided between the inner shaft ring 1 and the outer shaft ring 2. A refueling port 11 is provided at the upper portion of the sealing ring 9 away from one end. A sealing cover 12 is provided on the inner side of the refueling port 11. An oil delivery channel 10 connected to the refueling port 11 is provided inside the sealing ring 9.
[0034] When in use, the connecting shaft ring 3 is connected to the shaft of the external equipment, driving the inner shaft ring 1 to rotate. The inner shaft ring 1 realizes relative rotation with the outer shaft ring 2 through the double-row steel wire roller. The limit block 4 on the connecting shaft ring 3 cooperates with the limit groove 5 on the inner shaft ring 1 to prevent the connecting shaft ring 3 from axial displacement inside the inner shaft ring 1. When it is necessary to install or remove the connecting shaft ring 3, the fixing bolt 8 is rotated to pass through the threaded through hole 6 and threadedly connected or separated from the screw hole 7, thereby achieving the fixing or removal of the connecting shaft ring 3 and the inner shaft ring 1;
[0035] The sealing ring 9 plays a sealing role to prevent external dust, impurities, etc. from entering the space between the inner shaft ring 1 and the outer shaft ring 2 and affecting the normal operation of the bearing. When the bearing needs to be lubricated, the sealing cover 12 can be opened and lubricating oil can be injected into the oil channel 10 inside the sealing ring 9 through the oil filling port 11. The lubricating oil flows into the space between the inner shaft ring 1 and the outer shaft ring 2 through the oil channel 10 to lubricate the double-row steel wire roller, reduce friction and wear, and improve the service life and working efficiency of the bearing.
[0036] For example, Figure 3 As shown, the present invention further includes that the oil delivery channel 10 includes a first oil chamber 13 and a second oil chamber 14 .
[0037] During use, the lubricating oil first enters the first oil chamber 13, then flows to the second oil chamber 14, and finally flows into the space between the inner shaft ring 1 and the outer shaft ring 2, lubricating the double-row steel wire roller, reducing friction and wear, and improving the service life and working efficiency of the bearing.
[0038] For example, Figure 3 As shown, the present invention further includes that the oil filling port 11 is located at one end of the first oil chamber 13 and is in communication with the first oil chamber 13 .
[0039] During use, since the oil filling port 11 is located at one end of the first oil chamber 13 and is connected to the first oil chamber 13 , when the bearing needs to be lubricated, the sealing cover 12 is opened and lubricating oil is injected into the first oil chamber 13 through the oil filling port 11 .
[0040] For example, Figure 3 As shown, the present invention further includes a through hole 15 defined between the first oil chamber 13 and the second oil chamber 14 .
[0041] During use, after the lubricating oil enters the first oil chamber 13 , the lubricating oil will flow to the second oil chamber 14 through the through hole 15 since a through hole 15 is provided between the first oil chamber 13 and the second oil chamber 14 .
[0042] For example, Figure 3 As shown, the present invention further includes an oil outlet 16 formed at one end of the second oil chamber 14 away from the first oil chamber 13 .
[0043] During use, the lubricating oil flows out from the oil outlet 16 opened at one end of the second oil chamber 14 .
[0044] For example, Figure 3 As shown, the present invention also includes that the oil outlets 16 and the through holes 15 are arranged in a ring array in multiple groups and are staggered with each other.
[0045] When in use, this staggered arrangement can distribute the lubricating oil more evenly to the space between the inner shaft ring 1 and the outer shaft ring 2, fully lubricate the double-row steel wire roller, reduce the friction and wear between the double-row steel wire roller and the inner shaft ring 1 and the outer shaft ring 2, and improve the service life and working efficiency of the bearing.
[0046] It should be noted that the utility model is a double-row wire roller bearing. Insert the connecting shaft ring 3 into the two ends of the inner side of the inner shaft ring 1, ensure that the limit blocks 4 at the top and bottom edges of the outer side of the connecting shaft ring 3 are aligned with the limit grooves 5 at the top and bottom of the two ends of the inner shaft ring 1, pass the fixing bolts 8 through the threaded through holes 6 on the limit blocks 4, and screw them into the screw holes 7 on the inner wall of one end of the limit groove 5 of the inner shaft ring 1, tighten the fixing bolts 8 to achieve the fixation of the connecting shaft ring 3 and the inner shaft ring 1;
[0047] Connect the connecting shaft ring 3 of the installed bearing to the shaft of the external device;
[0048] During the use of the bearing, the inner shaft ring 1 will rotate under the drive of the connecting shaft ring 3. The inner shaft ring 1 realizes relative rotation with the outer shaft ring 2 through the double-row steel wire roller. The sealing ring 9 plays a sealing role to prevent external dust and impurities from entering the space between the inner shaft ring 1 and the outer shaft ring 2, ensuring the normal operation of the bearing.
[0049] When the bearing needs to be lubricated, first stop the equipment operation to ensure safety, open the sealing cover 12 to expose the oil filling port 11, and inject lubricating oil into the first oil chamber 13 through the oil filling port 11. The lubricating oil first enters the first oil chamber 13. Since a through hole 15 is provided between the first oil chamber 13 and the second oil chamber 14, the lubricating oil will flow to the second oil chamber 14 through the through hole 15, and the lubricating oil will flow out from the oil outlet 16 provided at one end of the second oil chamber 14 away from the first oil chamber 13. Since there are multiple groups of annular arrays of the oil outlets 16 and the through holes 15 and they are staggered with each other, the lubricating oil will be more evenly distributed to the space between the inner shaft ring 1 and the outer shaft ring 2, and the double-row steel wire roller will be fully lubricated. After the lubrication is completed, cover the sealing cover 12 to ensure a good seal.
[0050] When the connecting shaft ring 3 needs to be disassembled, stop the equipment first to ensure safety, rotate the fixing bolt 8 in the reverse direction to make it withdraw from the screw hole 7, and when the fixing bolt 8 is completely withdrawn, pull the connecting shaft ring 3 out of the inner shaft ring 1.
[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention can be applied to various types of applications.
[0052] The invention may be subjected to various changes and improvements, which are all within the scope of the invention to be protected. The scope of protection of the invention is defined by the appended claims and their equivalents.
