Description

Technical Field

[0001] The utility model relates to the technical field of roller bearings, in particular to a wear-resistant structure of a roller bearing. Background Art

[0002] Bearings are an important component in modern mechanical equipment, mainly used as core transmission parts. Roller bearings are a special bearing product, mainly used in mechanical equipment such as cranes. The most common use of roller bearings is as slide rail moving wheels.

[0003] In the prior art, an existing roller bearing has poor wear resistance during use, and it is inconvenient to add lubricating oil, which causes the roller bearing to be easily worn and damaged when used for a long time, and has poor practicality. In addition, when a roller bearing in the prior art is damaged, it is inconvenient to disassemble and replace a damaged single component, and it is usually replaced as a whole. This replacement method is costly and has poor practicality. Utility Model Content

[0004] The utility model mainly provides a roller bearing wear-resistant structure which is convenient for adding lubricating oil, thereby improving the wear resistance of the roller bearing and enabling each component to be disassembled and replaced separately when damaged, thereby reducing the maintenance cost.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wear-resistant structure of a roller bearing, including a bearing inner ring, a plurality of rollers are symmetrically distributed on the outer wall of the bearing inner ring, mounting plates are arranged on both sides of the bearing inner ring, and the opposite ends of the two mounting plates are rotatably connected to a plurality of rotating plates matching the rollers, limiting grooves are arranged in the two mounting plates on the outer sides of the rotating plates, connecting plates are arranged in the limiting grooves, the bearing outer ring is fixed on the outer wall of the connecting plate, and an oil storage tank is arranged on one end of the bearing inner ring on one side of each roller.

[0006] Preferably, a limiting column is fixed at one end of the multiple rotating plates in one of the mounting plates, and the limiting column passes through the roller and abuts against a rotating plate rotatably connected in another mounting plate. Through the setting of the rotating plate, the rotating plate can rotate with the roller, thereby reducing the wear on both ends of the roller, increasing the service life of the roller, and being more practical.

[0007] Preferably, an inner cavity matching the limit column is provided in the roller, and both ends of the roller are abutted against the two groups of rotating plates. By abutting both ends of the roller against the two groups of rotating plates, when the roller rotates, it will intermittently drive the rotating plates to rotate. When both the rotating plates and the rollers rotate, the wear on both ends of the rollers can be greatly reduced, thereby increasing their service life.

[0008] Preferably, the inner wall of the connecting plate contacts the outer walls of the roller and the rotating plate, and the two mounting plates are fixed to the inner ring of the bearing by a first locking bolt. The opposite ends of the two mounting plates are provided with a first opening matching the first locking bolt. Through the setting of the first locking bolt, the user can disassemble the two mounting plates at any time, which is convenient for separate replacement of damaged parts inside them. Through the setting of the first opening, the first locking bolt will not protrude from the outer wall of the device, thereby avoiding the phenomenon of uneven outer wall of the roller bearing.

[0009] Preferably, grooves are provided at the opposite ends of the two mounting plates, oil filling holes matching the oil storage tank are provided on the inner walls of the two grooves in the two mounting plates, and notches matching the rollers are provided on the outer wall of the inner ring of the bearing. Through the provision of the oil filling holes, the user can connect to an external oil filling device through the oil filling holes to quickly inject lubricating oil into the oil storage tank, making it convenient to apply lubricating oil to the rollers.

[0010] Preferably, a protective plate is provided in the groove, and the protective plate is fixed to the mounting plate by a second locking bolt. The opposite ends of the two protective plates are provided with a second opening matching the second locking bolt. The horizontal planes of the opposite ends of the two protective plates are parallel to the horizontal planes of the opposite ends of the two mounting plates. Through the provision of the protective plate, on the one hand, the oil filling hole is blocked to prevent the lubricating oil in the oil storage tank from being discharged through the oil filling hole. On the other hand, external dust is prevented from entering the oil storage tank through the oil filling hole to prevent it from being blocked by dust.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The utility model discloses that by the setting of the oil filling hole, the user can connect the external oil filling device through the oil filling hole to quickly inject the lubricating oil into the oil storage tank. When the roller rotates, its outer wall will continuously contact the lubricating oil in the oil storage tank, so as to achieve the effect of automatic oiling, reduce wear and improve its wear resistance. By the setting of the protective plate, on the one hand, the oil filling hole is blocked to prevent the lubricating oil in the oil storage tank from being discharged through the oil filling hole, and on the other hand, it prevents external dust and the like from entering the oil storage tank from the oil filling hole to prevent it from being blocked by dust. When the roller rotates, it will intermittently drive the rotating plate to rotate. When the rotating plate and the roller both rotate, it can greatly reduce the wear on both ends of the roller and improve its service life. By unscrewing the first locking bolt, the user can directly remove the mounting plate on one side of the bearing inner ring. At this time, one end of the roller is no longer limited by the removed mounting plate, and the user can directly take the damaged roller for separate replacement. The installation roller can be guided by the limiting column, and the installation is faster. BRIEF DESCRIPTION OF THE DRAWINGS

The horizontal planes of the opposite ends of the two protective plates 13 are parallel to the horizontal planes of the opposite ends of the two mounting plates 4. Through the arrangement of the protective plate 13, on the one hand, the oil filling hole 17 is blocked to prevent the lubricating oil in the oil storage tank 18 from being discharged through the oil filling hole 17, and on the other hand, external dust is prevented from entering the oil storage tank 18 through the oil filling hole 17 to prevent it from being blocked by dust.

[0026] The use method and working principle of the device: When the device is used, through the setting of the oil filling hole 17, the user can connect the external oil filling device through the oil filling hole 17 to quickly inject the lubricating oil into the oil storage tank 18. When the roller 3 rotates, its outer wall will continuously contact the lubricating oil in the oil storage tank 18 to achieve the effect of automatic oiling, reduce wear and improve its wear resistance. Through the setting of the protective plate 13, on the one hand, the oil filling hole 17 is blocked to prevent the lubricating oil in the oil storage tank 18 from being discharged through the oil filling hole 17, and on the other hand, it prevents external dust from entering from the oil filling hole 1 7 enters into the oil storage tank 18 to prevent it from being blocked by dust. When the roller 3 rotates, it will intermittently drive the rotating plate 5 to rotate.
