Description

Technical Field

[0001] The utility model relates to the technical field of roller bearings, in particular to a reinforced cylindrical roller bearing. Background Art

[0002] Bearings are a common mechanical equipment component used on shafts. There are bearings with different inner diameters according to the diameters of different shafts, and there are different types of bearings according to different force requirements.

[0003] Cylindrical roller bearings are concentric rolling bearings whose rolling elements are cylindrical rollers. The rollers are arranged in parallel and are set between the inner ring and the outer ring. The rollers are installed through the cage. Cylindrical roller bearings have a greater radial load capacity and are suitable for both heavy loads and high-speed rotation.

[0004] When a cylindrical roller bearing is in use, the cylindrical rollers inside it are mostly fixed in the support rings. However, during use, the friction between the cylindrical rollers and the support rings can easily cause damage to the cylindrical rollers, thereby affecting the life of the cylindrical roller bearings. In addition, the inner ring and the outer ring are mostly fixed and welded. When the inner ring is damaged alone, it needs to be replaced as a whole, which increases costs. Utility Model Content

[0005] The purpose of the utility model is to provide a reinforced cylindrical roller bearing to solve the problem that the cylindrical roller and the support ring of the existing bearings mentioned in the above background technology are mostly fixedly connected, and the friction during use easily causes damage to the cylindrical roller, and the inner ring and the outer ring are mostly fixedly welded, and when the inner ring is damaged alone, it needs to be replaced as a whole, which increases the cost. To achieve the above purpose, the utility model provides the following technical solutions: a reinforced cylindrical roller bearing, including a bearing outer ring, a detachable support ring is provided inside the bearing outer ring, and a plurality of cavities are opened on the side surface of the support ring, a cylindrical roller body is clamped in the middle of the cavity, and a detachable bearing inner ring is clamped inside the support ring.

[0006] Preferably, a screw is threadedly connected to the end of the outer ring of the bearing, a block is fixed to the top of the screw, and a groove is provided on the surface of the support ring to facilitate the vertical sliding of the block.

[0007] Preferably, a fixing rod is fixed inside the support ring, and sliders are sleeved on the outside of both ends of the fixing rod. Two sliders are provided, and an extrusion spring is fixedly connected between the two sliders. A connecting block is fixed to the end of the slider, and a connecting rod is hinged at the end of the connecting block. A fixing block is hinged at the end of the connecting rod. A sliding rod is fixed to the end of the fixing block, and a splint is fixedly connected to the end of the sliding rod, and an anti-wear pad is glued to the side wall of the splint.

[0008] Preferably, the anti-wear pad is in contact with both ends of the cylindrical roller body.

[0009] Preferably, a clamping block is fixed on the surface of the support ring, a support rod is fixed inside the clamping block, a return spring is connected to the end of the support rod, an insertion rod is fixed to the end of the return spring, and a push rod is fixed to the top of the insertion rod.

[0010] Preferably, the surface of the inner ring of the bearing is provided with a groove for easy engagement with the clamping block, the inner ring of the bearing is provided with a slot for engagement with the insertion rod, and the top of the clamping block is provided with a sliding groove for easy horizontal sliding of the push rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model discloses that the cylindrical roller body is clamped in the cavity of the supporting ring and the clamping plate is squeezed. The clamping plate is forced to drive the sliding rod to slide horizontally. At the same time, the connecting rods at both ends are forced to rotate to drive the sliding block to slide along the fixed rod and stretch the squeezing spring. When the cylindrical roller body is fully clamped, the squeezing spring releases the squeezing force and drives the sliding block to reset, so that the clamping plate fits the roller body and clamps it to install, so that the cylindrical roller body does not need to directly contact the supporting ring, effectively alleviating the friction generated between the cylindrical roller and the supporting ring during high-speed rotation, and improving the service life.

[0013] In the utility model, manually pressing the push rod drives the insertion rod to slide horizontally in the block and squeeze the reset spring, so that the insertion rod is embedded in the block and separated from the slot of the bearing inner ring to release the limit, so that the bearing inner ring can be quickly disassembled and replaced, and the manual rotation of the blocking block drives the screw to rotate, so that the blocking block and the support ring slot are on the same horizontal plane to facilitate the support ring to be quickly pulled out of the slot, so that the damaged bearing inner ring or support ring can be replaced, avoiding the overall replacement and increasing the use cost.

[0024] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a reinforced cylindrical roller bearing, including a bearing outer ring 1, a removable support ring 2 is provided inside the bearing outer ring 1, a plurality of cavities 3 are opened on the side surface of the support ring 2, a cylindrical roller body 4 is clamped in the middle of the cavity 3, and a removable bearing inner ring 5 is clamped inside the support ring 2.

[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a screw 101 is threadedly connected to the end of the bearing outer ring 1, a block 102 is fixed to the top of the screw 101, and a groove 210 is provided on the surface of the support ring 2 to facilitate the vertical sliding of the block 102.

[0027] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing rod 21 is fixed inside the support ring 2, and sliders 22 are sleeved on the outside of both ends of the fixing rod 21. Two sliders 22 are provided, and an extrusion spring 23 is fixedly connected between the two sliders 22. A connecting block 24 is fixed to the end of the slider 22, and a connecting rod 25 is hinged to the end of the connecting block 24. A fixing block 26 is hinged to the end of the connecting rod 25. A sliding rod 27 is fixed to the end of the fixing block 26. A splint 28 is fixedly connected to the end of the sliding rod 27, and an anti-wear pad 29 is glued to the side wall of the splint 28.

[0028] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the anti-wear pad 29 is fitted with both ends of the cylindrical roller body 4.

[0029] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a block 52 is fixed on the surface of the support ring 2, a support rod 53 is fixed inside the block 52, a return spring 54 is connected to the end of the support rod 53, an insertion rod 55 is fixed to the end of the return spring 54, and a push rod 56 is fixed to the top of the insertion rod 55.

[0030] It should be noted that, in the process of pushing the push rod 56 to slide, the return spring 54 will be squeezed, and when the return spring 54 releases the squeezing force, it will automatically reset and drive the insertion rod 55 to slide.

[0031] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the surface of the bearing inner ring 5 is provided with a groove 51 for easy engagement with the clamping block 52, the bearing inner ring 5 is provided with a slot for plugging with the insertion rod 55, and the top of the clamping block 52 is provided with a sliding groove for facilitating the horizontal sliding of the push rod 56.

[0032] It should be noted that the bearing inner ring 5, the bearing outer ring 1 and the support ring 2 are all detachably mounted, and any damage thereof can be disassembled and replaced, thus avoiding the increase of production cost by overall replacement.

[0033] It should be noted that the inner diameter of the slot 210 is consistent with the outer diameter of the block 102, and the slot 210 can pass through the block 102 for subsequent disassembly operations. When disassembly is not required, the block 102 and the slot 210 are in a cross-shaped cross state. The block 102 blocks the slot 210 to prevent the support ring 2 from loosening. At the same time, the inner diameter of the groove 51 is consistent with the inner diameter of the block 52, and the two can be clamped and fixed.

[0034] The use method and advantages of the utility model: When the reinforced cylindrical roller bearing is working, the working process is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the cylindrical roller body 4 is installed between the supporting ring 2, and the cylindrical roller body 4 is clamped in the cavity 3 of the supporting ring 2. During the clamping process, the clamping plate 28 is squeezed, and the clamping plate 28 is forced to drive the sliding rod 27 to slide horizontally. While sliding, the connecting rods 25 at both ends are immediately rotated by force and drive the slider 22 to slide horizontally along the outer wall of the fixed rod 21. While sliding, the squeezing spring 23 is stretched until the cylindrical roller body 4 is completely clamped therein, and the squeezing spring 23 releases the pressure to drive the two sliders 22 to reset, so that the clamping plate 28 is close to the two ends of the cylindrical roller body 4 to clamp and install it, and at the same time, an anti-wear pad 29 is arranged on its inner wall. The anti-wear pad 29 has the performance of wear resistance and anti-skid. Through this arrangement, the friction generated between the cylindrical roller and the supporting ring 2 during high-speed rotation can be effectively alleviated to avoid damage that affects the service life of the cylindrical roller bearing.

[0036] The cylindrical roller bearing is then connected to other accessories by bolts for use. Long-term use of the bearing inner ring 5 will cause wear. When replacing it, the push rod 56 is manually pressed to slide above the block 52. When the push rod 56 slides, it drives the insertion rod 55 to slide horizontally in the block 52, and at the same time squeezes the reset spring 54, so that the insertion rod 55 is embedded in the block 52 and separated from the slot in the bearing inner ring 5 to release the limit. Then the bearing is pulled out to be disassembled and replaced. The direction operation is sufficient during replacement. At the same time, the support ring 2 can also be replaced when it is damaged. During replacement, the block 102 is manually rotated to drive the screw 101 to rotate, so that the block 102 and the groove 210 on the surface of the support ring 2 are in the same horizontal direction. Then the support ring 2 is pulled out, and the groove 210 on the surface of the support ring 2 passes through the block 102 to achieve the effect of quick disassembly. Through this arrangement, a damaged component can be replaced separately, avoiding the need for overall replacement after damage, thereby reducing costs.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
