They are suitable for high-speed rotation and heavy loads. They are mainly composed of an inner ring, an outer ring, cylindrical rollers and a cage.

[0003] When the existing cylindrical roller bearings are assembled and installed, the inner ring, outer ring, cylindrical roller and retainer are placed correspondingly, and then the inner ring of the bearing is knocked to clamp the inner ring of the bearing between multiple groups of cylindrical rollers. When the inner ring of the bearing is hit by external force, it is easy to separate from the cylindrical rollers, causing the bearing to fall apart. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides an energy-saving and environmentally friendly cylindrical roller bearing, which solves the problem that the existing cylindrical roller bearing is connected by combining the inner ring, outer ring, cylindrical roller and retaining frame by knocking, and the inner ring of the bearing is easily separated from the cylindrical roller when hit by external force, causing the bearing to fall apart.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an energy-saving and environmentally friendly cylindrical roller bearing, comprising a bearing outer ring, a retaining frame is provided inside the bearing outer ring, a plurality of mounting grooves are provided on the surface of the retaining frame at equal angles, and roller bodies are inlaid and rollingly installed inside the mounting grooves, protrusions are fixedly installed at the central position between two adjacent mounting grooves on both sides of the inner wall of the retaining frame, a bearing inner ring is provided on one side of the inner part of the retaining frame between the multiple groups of roller bodies, six groups of limit blocks are fixedly installed at equal angles on the surface of one side of the bearing inner ring, an inner ring pressure ring is provided at one end of the bearing inner ring, a fixed pressure ring is provided at the end of the bearing inner ring close to the inner ring pressure ring, and six groups of fixed pressure blocks are fixedly installed at equal angles on the surface of the fixed pressure ring.

[0006] As a further solution of the utility model: an oil groove is provided at the bottom of the inner wall of the outer ring of the bearing, and the oil groove is filled with a proper amount of lubricating oil.

[0007] As a further solution of the utility model: a mounting shaft is fixedly installed inside the oil groove, an oil brush wheel is rollingly installed on the surface of the mounting shaft, and the top of the oil brush wheel surface extends through the oil groove to the inner wall of the bearing outer ring and contacts the roller body.

[0008] As a further solution of the utility model: six groups of limiting grooves are provided at equal angles on one side of the inner wall of the inner ring pressure ring, and the limiting grooves correspond to the limiting blocks.

[0009] As a further solution of the utility model: six groups of fixing grooves are provided at equal angles on the inner wall of the inner ring pressure ring away from the limiting groove, and the fixing grooves correspond to the fixed pressure blocks.

[0010] As a further solution of the utility model: six groups of fixing bolts are arranged at equal angles on the surface of the fixing pressure ring, and the fixing bolts pass through the fixing pressure ring and are connected to the inner ring of the bearing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The energy-saving and environment-friendly cylindrical roller bearing is provided with a bearing inner ring, an inner ring pressure ring, a fixed pressure ring and fixing bolts. After the retaining frame and the roller body are clamped inside the bearing outer ring, the bearing inner ring and the inner ring pressure ring are controlled to be clamped on both sides between multiple groups of roller bodies, so that the limiting groove is clamped on the surface of the corresponding limiting block, and then the fixed pressure ring is covered on the side of the inner ring pressure ring away from the bearing inner ring, so that the fixed pressure block is clamped in the corresponding fixing groove, and the fixing bolts are tightened to ensure that the fixed pressure ring can clamp and fix the inner ring pressure ring on one side of the bearing inner ring, so that the bearing inner ring and the inner ring pressure ring can be clamped between multiple groups of roller bodies, and the bearing inner ring and the inner ring pressure ring are prevented from being separated from the inside of the roller body at will.

[0013] 2. The energy-saving and environment-friendly cylindrical roller bearing is provided with a bearing outer ring, an oil groove and an oil brush wheel. After the bearing outer ring is fixed, a proper amount of lubricating oil is injected into the oil groove, and then the retaining frame, the roller body and the bearing inner ring and other components are assembled and connected. The inner ring of the bearing is rotated to drive the retaining frame and the roller body to rotate on the inner wall of the bearing outer ring under the action of friction. At the same time, the oil brush wheel rolls in the oil groove to immerse the surface of the oil brush wheel with lubricating oil, ensuring that the oil brush wheel can apply the lubricating oil to the surface of the roller body, thereby reducing the friction between the roller body and the bearing outer ring, the bearing inner ring and the inner ring pressure ring.

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: an energy-saving and environmentally friendly cylindrical roller bearing, including a bearing outer ring 1, an oil groove 2 is provided at the bottom of the inner wall of the bearing outer ring 1, and the oil groove 2 is filled with a proper amount of lubricating oil. A mounting shaft 3 is fixedly installed inside the oil groove 2, and a brush oil wheel 4 is rollingly installed on the surface of the mounting shaft 3, and the top of the surface of the brush oil wheel 4 passes through the oil groove 2 and extends to the inner wall of the bearing outer ring 1 to contact the roller body 8. Because the oil groove 2 and the brush oil wheel 4 are provided, after injecting lubricating oil into the oil groove 2, multiple groups of roller bodies 8 are controlled to pass through the brush oil wheel 4, and under the action of friction, the brush oil wheel 4 is rolled inside the oil groove 2, ensuring that the brush oil wheel 4 can evenly brush the lubricating oil from the inside of the oil groove 2 onto the surface of the roller body 8.

[0021] A retainer 5 is provided inside the outer ring 1 of the bearing, and a plurality of groups of mounting grooves 6 are provided on the surface of the retainer 5 at equal angles, and a roller body 8 is inlaid and rollingly installed inside the mounting groove 6. A convex block 7 is fixedly installed at the central position between two adjacent groups of mounting grooves 6 on both sides of the inner wall of the retainer 5, and a bearing inner ring 9 is provided on one side inside the retainer 5 between the plurality of groups of roller bodies 8. By providing the retainer 5 and the mounting grooves 6, the plurality of groups of roller bodies 8 are inserted into the corresponding mounting grooves 6 from inside the retainer 5, ensuring that when the plurality of groups of roller bodies 8 rotate inside the outer ring 1 of the bearing, the roller bodies 8 do not collide with each other;

[0022] Six groups of limit blocks 10 are fixedly installed at equal angles on the surface of one side of the bearing inner ring 9, an inner ring pressure ring 11 is provided at one end of the bearing inner ring 9, and six groups of limit grooves 12 are provided at equal angles on one side of the inner wall of the inner ring pressure ring 11, and the limit grooves 12 correspond to the limit blocks 10. Because the limit blocks 10 and the limit grooves 12 are provided, after the bearing inner ring 9 and the inner ring pressure ring 11 are clamped on both sides between multiple groups of roller bodies 8, the limit grooves 12 are clamped on the corresponding limit block 10 surfaces to ensure that the bearing inner ring 9 and the inner ring pressure ring 11 will not be misaligned or deflected when the bearing rotates.

[0023] Six groups of fixed grooves 13 are provided at equal angles on the inner wall of the inner ring pressure ring 11 away from the limiting groove 12, and the fixed grooves 13 correspond to the fixed pressure blocks 15. A fixed pressure ring 14 is provided at one end of the bearing inner ring 9 close to the inner ring pressure ring 11, and six groups of fixed pressure blocks 15 are fixedly installed at equal angles on the surface of the fixed pressure ring 14. Because the fixed grooves 13 and the fixed pressure blocks 15 are provided, after the inner ring pressure ring 11 is clamped on one side of the bearing inner ring 9, the fixed pressure ring 14 is controlled to be clamped on one side of the inner ring pressure ring 11, so that the fixed pressure blocks 15 are clamped into the corresponding fixed grooves 13, ensuring that when the fixed pressure ring 14 clamps the bearing inner ring 9 and the inner ring pressure ring 11, the fixed pressure ring 14 will not rotate arbitrarily and be misplaced on one side of the inner ring pressure ring 11.

[0024] Six groups of fixing bolts 16 are provided at equal angles on the surface of the fixed pressure ring 14, and the fixing bolts 16 pass through the fixed pressure ring 14 and are connected to the bearing inner ring 9. By providing the fixing bolts 16, after the fixed pressure ring 14 is clamped on one side of the inner ring pressure ring 11, the fixing bolts 16 are tightened to connect the fixed pressure ring 14 to the bearing inner ring 9, so that the inner ring pressure ring 11 is clamped between the bearing inner ring 9 and the fixed pressure ring 14, ensuring that the bearing inner ring 9 and the inner ring pressure ring 11 are clamped on both sides of the roller body 8 to clamp and limit the roller body 8 and will not be separated at will.

[0025] The working principle of the utility model is:

[0026] Put the retainer 5 into the bearing outer ring 1, and at the same time roll and inlay the corresponding roller body 8 into the installation groove 6. After the roller body 8 is respectively inserted into the multiple groups of installation grooves 6, the retainer 5 and the bearing outer ring 1 are sleeved on the surface of the bearing inner ring 9, so that the roller body 8 is stuck on the surface of the bearing inner ring 9, and then the inner ring pressure ring 11 is correspondingly stuck on the surface of the bearing inner ring 9, and the limiting groove 12 is stuck on the surface of the corresponding limiting block 10, and the fixed pressure ring 14 is correspondingly covered inside the inner ring pressure ring 11, and the fixed pressure block 15 is stuck in the corresponding fixing groove 13, and the fixing bolts 16 are tightened to fix the bearing inner ring 9 and the inner The ring pressure ring 11 and the fixed pressure ring 14 are connected and fixed to ensure that the bearing inner ring 9 and the inner ring pressure ring 11 are stuck on both sides between the multiple groups of roller bodies 8, the bearing outer ring 1 is erected to make the oil groove 2 at the bottom, and an appropriate amount of lubricating oil is injected into the oil groove 2 through the gap between the roller body 8 and the bearing outer ring 1, and the retaining frame 5 is controlled to drive the roller body 8 to rotate inside the bearing outer ring 1, so that the roller body 8 rolls through the oil brush wheel 4, ensuring that the oil brush wheel 4 brushes the lubricating oil on the surface of the roller body 8, thereby reducing the friction between the roller body 8 and the bearing outer ring 1, the bearing inner ring 9 and the inner ring pressure ring 11.
