Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a roller bearing which is easy to maintain. Background Art

[0002] Roller bearings, as key components in mechanical transmission systems, are widely used in various industrial equipment, automobiles, aerospace, and other fields. Their main function is to support rotating parts and reduce friction, ensuring the efficient and stable operation of equipment. However, during long-term use, traditional roller bearings face a series of technical and maintenance challenges. These issues are directly related to the performance, lifespan, and operational reliability of the equipment.

[0003] The core components of the roller bearing in the prior art include an inner ring, an outer ring, and a roller located between the two. As the part that directly bears the load and rolls, the surface of the roller will inevitably wear under long-term high-speed rotation and heavy load. This wear not only leads to a gradual decrease in the roller diameter, but also may cause an increase in surface roughness, thereby generating fine iron chips and abrasive particles inside the bearing. The presence of these iron chips and abrasive particles will, on the one hand, aggravate the friction and wear inside the bearing, forming a vicious cycle; on the other hand, they may also invade the bearing's lubrication system, reducing the lubrication effect, further affecting the bearing's rotation smoothness and life. More seriously, the deformation and wear of the roller will also lead to a decrease in the overall geometric accuracy of the bearing and cause slight deformation of the bearing's internal structure. This deformation will not only cause uneven stress distribution in the bearing during operation, accelerating fatigue damage of the bearing, but also cause abnormal noise and vibration when the bearing rotates, seriously affecting the smooth operation and environmental adaptability of the equipment. In addition, the direct replacement steps of the roller bearing as a whole are relatively cumbersome, which will affect its use during processing.

[0004] In order to solve the above problems, during use, the roller bearing can be disassembled and maintained according to the actual problems, and the iron filings generated inside it due to long-term operation can be cleaned to avoid affecting the lubrication effect. The rollers that are deformed due to operation can be replaced, so as to make the long-term use of the roller bearing more convenient. For this reason, we have proposed a roller bearing that is easy to maintain. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-3 A roller bearing that is easy to maintain includes a bearing body 1, which includes an inner shaft ring 2, an outer shaft ring 3, an inner groove 4, and rollers 5. The inner wall surface of the outer shaft ring 3 is provided with an inner groove 4 for rolling. The outer shaft ring 3 is sleeved on the outer side of the inner shaft ring 2, and a plurality of rollers 5 are rotatably installed between the inner shaft ring 2 and the outer shaft ring 3. The invention also includes:

[0027] The maintenance component is arranged on one side of the inner shaft ring 2 and the outer shaft ring 3, and is used to maintain and clean the bearing body 1.

[0028] Furthermore, a slider 6 for sliding is fixedly installed on one side of the inner shaft ring 2, and the slider 6 is slidably installed on the side protection ring 7. The side protection ring 7 is fixedly connected to one side of the outer ring 3. Through the setting of the slider 6 and the side protection ring 7, stable guidance and support of the roller bearing during operation are achieved, which not only enhances the structural stability of the roller bearing, but also reduces the wear caused by friction, thereby extending the service life of the roller bearing and improving its operation stability.

[0029] Furthermore, a plug-in groove 8 for plug-in is provided on the outer wall surface of the inner shaft ring 2, and a separating ring 9 for limiting is installed on the outer wall surface of the inner shaft ring 2 through the plug-in groove 8. The setting of the plug-in groove 8 and the separating ring 9 makes the roller bearing more convenient during assembly and maintenance. The addition of the separating ring 9 effectively limits the axial displacement of the roller 5 during operation, further improving the load-bearing capacity and operation stability of the roller bearing.

[0030] Furthermore, the separator ring 9 is provided with a number of equally spaced roller grooves 10 for separation, and the rollers 5 are rotatably mounted within the roller grooves 10. The arrangement of the roller grooves 10 allows each roller 5 to independently bear the load and reduces the mutual influence between the rollers. This not only improves the bearing's load-bearing capacity but also makes the load distribution more uniform, thereby extending the overall service life of the roller bearing.

[0031] Furthermore, the maintenance component includes a side ring plate 11, a lubrication hole 12 and a guide rod 13. The side ring plate 11 is detachably mounted on one side of the outer ring 3, and a lubrication hole 12 for oil lubrication is provided at a position between the inner shaft ring 2 and the outer ring 3 on the side ring plate 11. A guide rod 13 for guiding is also fixedly mounted on the inner side of the side ring plate 11 at a position corresponding to the inner shaft ring 2. The provision of the maintenance component greatly facilitates the maintenance of the roller bearing. By regularly oiling, the friction between the roller 5 and the inner and outer rings can be effectively reduced, and wear can be reduced. The guide rod 13 ensures the stability of the inner shaft ring 2 during rotation, which is more practical.

[0032] Furthermore, the end of the guide rod 13 is spherical.

[0033] Furthermore, an insertion groove 14 for insertion is opened on one side of the inner shaft ring 2 at a position corresponding to the guide rod 13, and an annular groove 15 that slides with the guide rod 13 is opened on the side of the inner shaft ring 2 at a position corresponding to the insertion groove 14. Through the setting of the insertion groove 14 and the annular groove 15, the guide rod 13 can enter the interior of the annular groove 15 more accurately, which not only improves the accuracy of the maintenance work, but also ensures the operating stability and reliability of the roller bearing after maintenance.

[0034] Instructions

[0035] After using for a period of time, if the bearing makes abnormal noise and vibration and needs to be maintained, first remove the side ring plate 11, and then remove the separator ring 9 as a whole from the outer wall surface of the inner shaft ring 2 through the removal of the side ring plate 11. After the separator ring 9 is removed, several rollers 5 will lose the limit of the roller groove 10, and then the inner shaft ring 2 can be removed from the inside of the outer ring 3, and several rollers 5 can be taken out. Then, according to actual needs, the debris and other debris inside the inner groove 4 and the roller groove 10 can be cleaned, and the roller 5 can be inspected to see if it is deformed. After the maintenance and cleaning is completed, the several components can be reassembled in turn and then put into use. Through the mutual cooperation between the above-mentioned structures, this device can disassemble and maintain the roller bearing according to actual problems, clean the iron filings generated in it due to long-term operation to avoid affecting the lubrication effect, and replace the rollers that are deformed due to operation, which is more convenient for the long-term use of the roller bearing and more practical.
