Description

Technical Field

[0001] This invention relates to the field of bearing technology, specifically to a high-load-bearing split double-row tapered roller bearing. Background Technology

[0002] During operation, double-row tapered roller bearings experience relative motion between the rolling elements and raceways, and between the roller end faces and flanges, resulting in friction. Good lubrication forms an oil film on these contact surfaces, separating the metal surfaces and causing friction to occur between fluid molecules within the oil film, rather than direct metal-to-metal friction. This significantly reduces the coefficient of friction, minimizing energy loss and heat generation, and also significantly reduces wear on bearing components, extending bearing life. For example, in heavy machinery and automotive industries, well-lubricated double-row tapered roller bearings can operate stably under high load and high speed conditions, while insufficient lubrication can cause rapid bearing wear and even serious malfunctions such as seizure.

[0003] Double-row tapered roller bearings typically have a complex structure, consisting of multiple components such as an inner ring, outer ring, rollers, and cage. Their internal space is relatively narrow and irregular, which poses significant challenges to the uniform distribution of the lubricating medium. For example, the small clearance between the rollers and raceways makes it difficult for lubricating oil or grease to fully penetrate and cover the entire contact area, easily leading to uneven lubrication in certain areas. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a high load-bearing split double-row tapered roller bearing, which can effectively solve the problem affecting the service life of bearings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a high-load-bearing split double-row tapered roller bearing, comprising an outer bearing ring and two inner bearing rings; both inner bearing rings are located inside the outer bearing ring and are detachably connected to it; a roller body is disposed inside the inner bearing ring; a washer is disposed between the two inner bearing rings; a mounting box is fixedly connected to the outer side of the outer bearing ring; an oil injection port is opened on one side of the outer bearing ring; sealing rings are snapped into both ends of the outer bearing ring; and auxiliary components are disposed inside the outer bearing ring.

[0006] According to the above-mentioned high load-bearing split double-row tapered roller bearing, the auxiliary component includes multiple inner tubes, which are equidistantly distributed inside the outer ring of the bearing. The multiple inner tubes are connected to each other through connecting pipes. The bottom of the oil inlet is fixedly connected to a connecting pipe, which is fixedly connected to one of the inner tubes. Guide grooves are provided on both sides of the inner wall of the outer ring of the bearing. An adsorption pad is provided inside the guide groove. An oil outlet is opened on the inner wall of the inner tube, and the oil outlet is connected to the guide groove.

[0007] According to the above-mentioned high load-bearing split double-row tapered roller bearing, a mounting bracket is fixedly installed inside the connecting pipe, and a dispersion plate is rotatably connected to the midpoint inside the mounting bracket.

[0008] According to the above-mentioned high load-bearing split double-row tapered roller bearing, a slider is slidably connected inside the mounting box, springs are fixedly connected to the inner walls on both sides of the slider, the other end of the spring is fixedly connected to the slider, a connecting block is fixedly connected to one side of the slider, and a sealing plug is fixedly connected to the bottom of the connecting block. The sealing plug blocks or opens the oil filling port.

[0009] According to the above-mentioned high load-bearing split double-row tapered roller bearing, a plurality of snap-fit ​​pins are fixedly connected to one side of the sealing ring, and a snap-fit ​​groove is provided at one end of the outer ring of the bearing, wherein the snap-fit ​​pins snap into the snap-fit ​​groove.

[0010] According to the above-mentioned high load-bearing split double-row tapered roller bearing, the outer ring of the bearing is provided with reinforcing ribs at the positions that do not contact the inner tube and the connecting tube.

[0011] According to the above-mentioned high load-bearing split double-row tapered roller bearing, a sealing gasket is provided at one end of the sealing ring near the outer ring of the bearing.

[0012] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. Through the auxiliary components, lubricating oil is injected from the oil inlet. The lubricating oil then contacts the dispersing plate, causing the dispersing plate to rotate. The dispersing plate, in conjunction with the connecting pipe, evenly delivers the lubricating oil to the interior of multiple inner tubes. The inner tubes, in conjunction with the connecting pipe, inject the lubricating oil through the oil outlet into the guide groove. The absorbent pad inside the guide groove absorbs the lubricating oil while evenly coating the surface of the roller body, preventing localized lubrication and thus improving the service life of the invention. Furthermore, the absorbent pad absorbs excess lubricating oil, and the dispersing plate prevents backflow of lubricating oil during injection, ensuring the normal operation of the invention.

[0013] 2. By moving the connecting block, the sealing plug can be moved, and the two springs can be compressed and stretched, thereby exposing the oil inlet and facilitating the user to perform oil filling. After oil filling, the springs ensure that the slider and sealing plug are reset, thus sealing the oil inlet and ensuring stable operation of the invention during use. Attached Figure Description

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

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: Refer to Figures 1 to 6A high-load-bearing split-type double-row tapered roller bearing includes an outer bearing ring 1 and two inner bearing rings 2. Both inner bearing rings 2 are located inside the outer bearing ring 1 and are detachably connected to it. A roller body 28 is disposed inside the inner bearing ring 2. A washer 3 is disposed between the two inner bearing rings 2. A mounting box 20 is fixedly connected to the outer side of the outer bearing ring 1. An oil inlet 12 is provided on one side of the outer bearing ring 1. Sealing rings 11 are snapped onto both ends of the outer bearing ring 1. An auxiliary component is disposed inside the outer bearing ring 1. By making the outer bearing ring 1, inner bearing rings 2, and washer 3 detachably connected, the maintenance and repair of the invention are facilitated, and installation and disassembly are relatively convenient. Furthermore, the auxiliary component improves the efficiency of oil injection and extends the service life of the invention.

[0020] The auxiliary components include multiple inner tubes 13, which are equidistantly distributed inside the outer ring 1 of the bearing. The multiple inner tubes 13 are connected to each other through connecting pipes 14. The bottom of the oil inlet 12 is fixedly connected to a connecting pipe 19, which is fixedly connected to one of the inner tubes 13. Guide grooves 18 are provided on both sides of the inner wall of the outer ring 1 of the bearing. An adsorption pad is provided inside the guide groove 18. An oil outlet 15 is opened on the inner wall of the inner tube 13, which is connected to the guide groove 18. The auxiliary components can make the lubricating oil evenly applied to the surface of the roller body 28, avoiding the phenomenon of local lubrication of the roller body 28. A mounting bracket 191 is fixedly installed inside the connecting pipe 19. A dispersing plate 192 is rotatably connected to the midpoint of the mounting bracket 191. Through the cooperation of the dispersing plate 192 and the connecting pipe 19, the lubricating oil can be evenly injected into the interior of the multiple inner tubes 13. Since the dispersing plate 192 is umbrella-shaped, the phenomenon of lubricating oil backflow can be avoided.

[0021] The mounting box 20 has a sliding block 21 inside. Springs 22 are fixedly connected to the inner walls of both sides of the slider 21, with the other end of each spring fixedly connected to the slider 21. A connecting block 23 is fixedly connected to one side of the slider 21, and a sealing plug 24 is fixedly connected to the bottom of the connecting block 23. The sealing plug 24 blocks or opens the oil inlet 12. Through the cooperation of the slider 21, springs 22, and sealing plug 24, the connecting pipe 19 is sealed, improving the sealing performance. Multiple clips are fixedly connected to one side of the sealing ring 11. The bearing outer ring 1 has a locking groove 112 at one end of the connecting post 111. The locking post 111 engages with the locking groove 112. The engagement of the locking post 111 and the locking groove 112 facilitates the installation and removal of the sealing ring 11. The bearing outer ring 1 has reinforcing ribs at the position where it does not contact the inner tube 13 and the connecting tube 14. The reinforcing ribs improve the stability of the invention. The sealing ring 11 has a sealing gasket at the end near the bearing outer ring 1. The sealing gasket further ensures the sealing performance of the invention.

[0022] The working principle of this invention is as follows: By moving the connecting block 23, the sealing plug 24 can be moved, compressing and stretching the two springs 22, thereby exposing the oil inlet 12 for easy oiling. After oiling, the springs 22 return to their original positions, ensuring the sealing of the oil inlet 12 and guaranteeing stable operation of the invention. Lubricating oil is injected through the oil inlet 12, then contacts the dispersing plate 192, causing it to rotate. The lubricating oil is then distributed through the interaction between the dispersing plate 192 and the connecting pipe 19. The oil is evenly delivered to the interior of multiple inner tubes 13, and through the cooperation of the inner tubes 13 and the connecting tubes 14, the lubricating oil is injected into the interior of the guide groove 18 through the oil outlet 15. Then, the lubricating oil is absorbed by the adsorption pads set inside the guide groove 18, and is evenly coated on the surface of the roller body 28, avoiding the situation of only lubricating a part of the roller body 28, thereby improving the service life of the invention. The adsorption pads can absorb excess lubricating oil, and since the dispersing sheet 192 is set in an umbrella shape, backflow can be effectively prevented, thereby ensuring the normal use of the invention.

[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
