This type of bearing stems from the demand for high-performance materials. Carburized steel has high surface hardness, good wear resistance, and good internal toughness. It can withstand large impact loads and has become an ideal material for manufacturing high-performance bearings. At the same time, by optimizing the bearing design, such as improving the shape, size, and arrangement of the rollers, and using advanced lubrication technology, the friction torque of the bearing can be significantly reduced, and the operating efficiency and life of the bearing can be improved. This type of bearing not only meets the needs of modern industry for high-performance, low-energy consumption, and long-life bearings, but also conforms to the global trend of energy conservation and environmental protection.

[0003] The existing tapered roller bearing body is a type of bearing specially designed to withstand axial and radial loads, and is particularly suitable for situations where heavy loads and impact loads are applied. The main structure of this bearing includes an outer ring, an inner ring, a set of tapered rollers, and a cage. The outer ring is usually fixed in the bearing seat, while the inner ring fits tightly with the rotating shaft. The rollers roll between the inner and outer rings, and the cage ensures that the rollers are evenly distributed to reduce friction and wear.

[0004] However, the existing tapered roller bearing body does not have a proper lubricating oil distribution groove, so that the lubricant cannot be evenly distributed to the various contact surfaces of the bearing, which will lead to insufficient and uneven lubrication, which will not only increase the friction and wear of the bearing, but also cause the bearing to overheat, increase noise and vibration, and reduce the operating efficiency and accuracy of the mechanical system. For this reason, carburized steel low friction torque tapered roller bearings are proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 - Figure 3The utility model provides an embodiment: a carburized steel low friction torque tapered roller bearing, comprising an outer ring 1, a tapered roller bearing body 3 is rotatably connected inside the outer ring 1, retainers 4 are rotatably connected on both sides of the outer wall of the tapered roller bearing body 3, an inner ring 2 is slidably connected to the outer wall of the tapered roller bearing body 3, the outer wall of the tapered roller bearing body 3 is slidably connected to the inside of the placement groove 18, the outer ring 1 and the inner ring 2 are both provided with placement grooves 18, an oil filling hole 5 and a lubricating oil flow groove 6 are provided inside the outer ring 1, the oil filling hole 5 is provided on the inner wall of the lubricating oil flow groove 6, a lubricating groove 1 7 and a lubricating groove 2 8 in an annular array are provided inside the outer ring 1, a stopper 19 is fixedly connected inside the outer ring 1, a sealing component is provided inside the outer ring 1, and the sealing component is used to seal the oil filling hole 5;

[0023] Specifically, when the carburized steel low friction torque tapered roller bearing is filled with lubricating liquid, the lubricating oil is first injected through the oil filling hole 5 located on the outer ring 1 of the bearing. This process ensures that the lubricating oil can directly enter the internal structure of the bearing. As the lubricating oil is injected, it will quickly fill the lubricating oil flow groove 6 around the oil filling hole 5. The lubricating oil flow groove 6 is carefully designed to guide the lubricating oil to be evenly distributed along the inner wall of the outer ring 1 to ensure that the lubricating oil is evenly distributed in the bearing. The shape and layout of the lubricating oil flow groove 6 are optimized to achieve uniform flow of the lubricating oil. In addition, the lubricating oil flow groove 6 is connected to the lubricating groove 8, and the lubricating groove 8 is connected to the lubricating groove 8. 8 further ensures that the lubricating oil can be evenly distributed to the rollers and cage 4 of the tapered roller bearing body 3. The design of the dual lubrication path enables the lubricating oil to effectively lubricate the radial and axial load areas of the bearing at the same time, thereby significantly reducing the friction torque of the bearing. Through this design, the lubricating oil can not only evenly cover all contact surfaces of the bearing, but also reduce the generation of friction and heat, extend the service life of the bearing and achieve low friction torque. The outer ring 1, inner ring 2, tapered roller bearing 3 and cage 4 are all made of carburized steel, which not only improves the operating efficiency of the bearing, but also reduces energy loss.

[0024] Reference Figure 1 - Figure 3 The sealing assembly includes a sealing cover 14 and a limiting block 17. The outer wall of the sealing cover 14 is fixedly connected to one side of the outer wall of the limiting block 17. The limiting block 17 and the outer wall of the sealing cover 14 are both slidably connected to the inner part of the outer ring 1.

[0025] Specifically, in the carburized steel low friction torque tapered roller bearing, the sealing cover 14 can prevent the lubricating oil from leaking from the oil filling port due to vibration, tilt or pressure change, ensuring that an appropriate amount of lubricating oil is retained inside the bearing to maintain its lubrication effect.

[0026] Reference Figure 1 - Figure 3A second groove 16 is provided inside the sealing cover 14, a second limiting groove 15 is provided inside the outer ring 1, the outer wall of the limiting block 17 is slidably connected inside the limiting groove 15, a dust cover 10 is slidably connected inside the outer ring 1, a limiting groove 9 is provided inside the outer ring 1, the outer wall of the dust cover 10 is slidably connected inside the limiting groove 9, a mounting groove 11 is provided inside the outer ring 1, a sealing gasket 12 is slidably connected to the top of the dust cover 10, the top of the sealing gasket 12 is fixedly connected to the inside of the mounting groove 11, and a groove 13 is provided inside the dust cover 10;

[0027] Specifically, when installing the dust cover 10 and the sealing gasket 12, the sealing gasket 12 needs to be accurately placed in the installation groove 11 first. The installation of the sealing gasket 12 is crucial. It is responsible for preventing external pollutants such as dust, moisture and impurities from entering the bearing, thereby protecting the bearing from contamination and corrosion. When installing the sealing gasket 12, ensure that it fits tightly with the installation groove 11 to ensure the sealing effect. After installing the sealing gasket 12, the next step is to install the dust cover 10 in place. The design of the dust cover 10 is to provide additional protection for the bearing to prevent the intrusion of dust to maintain the good condition of the bearing. In working state, special attention should be paid to the installation of the dust cover 10. When installing the dust cover 10, its limit groove 9 plays a key role. The limit groove 9 cooperates with the raised part of the outer wall of the dust cover 10 to ensure that the dust cover 10 remains stable during the operation of the bearing through physical limitation to prevent it from falling off due to vibration or impact. This design not only improves the reliability of the bearing, but also simplifies the maintenance process, because the existence of the limit groove 9 makes the installation and disassembly of the dust cover 10 more convenient. After completing the installation of the dust cover 10 and the sealing gasket 12, the carburized steel low friction torque tapered roller bearing can be put into use.

[0028] Working principle: When filling the carburized steel low friction torque tapered roller bearing with lubricating liquid, the staff first needs to use a hook to extend it into the groove 2 16, take out the sealing cover 14, and then add the lubricating oil into the outer ring 1 through the oil filling hole 5, and then the lubricating oil enters the lubricating oil flow groove 6 from the oil filling hole 5. At this time, the lubricating oil can flow through the lubricating oil flow groove 6 inside the outer ring 1, and then lubricate the tapered roller bearing body 3 through the lubricating oil flow groove 6 and the lubrication groove 2 8. When installing the dust cover 10 and the sealing gasket 12, it is necessary to first install the sealing gasket 12 in the installation groove 11. After the installation is completed, the dust cover 10 is installed between the outer ring 1 and the inner ring 2. The limiting groove 1 9 limits the raised part of the outer wall of the dust cover 10 to prevent the dust cover 10 from falling off. After the installation is completed, the carburized steel low friction torque tapered roller bearing can be used.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
