[0002] The cylindrical roller bearing is a centripetal rolling bearing with cylindrical rollers as rolling bodies. The internal structure of the cylindrical roller bearing adopts parallel arrangement of rollers, and interval retainers or isolation blocks are arranged between the rollers to prevent inclination of the rollers or mutual friction between the rollers.

[0003] The existing cylindrical roller bearings mostly have no dustproof structure, so that dust and impurities from the outside can easily enter the inside of the bearing, thereby affecting the stable rotation of the cylindrical rollers. In addition, although the bearings with dustproof rings can prevent dust from entering the inside of the rollers, the dustproof rings on the bearings are mostly inconvenient to disassemble, thereby affecting the maintenance work of the internal structure of the bearing and having certain limitations.

[0004] Therefore, it is necessary to provide a novel cylindrical roller bearing to solve the above problems. UTILITY MODEL CONTENTS

[0008] Preferably, the cylindrical rollers are arranged in a plurality of forms, and the plurality of cylindrical rollers are arranged in a ring array about the center of the circular ring retainer.

[0009] Preferably, connecting studs are arranged on both sides of the top surface and the bottom surface of the circular ring retainer, through holes are arranged in the dustproof sealing ring and correspond to the connecting studs, and lock nuts are threadedly connected to the outer walls of the connecting studs at one end and pass through the through holes.

[0010] Preferably, the top surface of the outer ring, the top surface of the connecting stud, and the top surface of the inner ring are in the same horizontal plane.

[0011] The beneficial effects of this utility model are as follows: the basic structure of the bearing is achieved through the outer ring, inner ring, circular ring cage, and cylindrical rollers; the upper and lower dustproof sealing rings are used to prevent dust from entering the internal structure of the bearing; the outer and inner circular ring rubber pads improve the sealing performance between the outer and inner rings, thus enhancing the reliability of the dustproof sealing ring in isolating external dust and impurities; by rotating the locking nut to disengage it from the connecting stud, the dustproof sealing ring can be removed from the connecting stud, allowing for quick disassembly of the dustproof sealing ring and facilitating the inspection of the internal structure of the bearing, which helps ensure the stability of the bearing during long-term use.

[0019] See Figures 1 to 5 A novel cylindrical roller bearing is shown, comprising an outer ring 1 and an inner ring 2. A circular ring cage 3 is provided between the outer ring 1 and the inner ring 2. A cylindrical roller 4 is rotatably mounted in the circular ring cage 3. Dustproof sealing rings 5 ​​are provided at the top and bottom between the inner ring of the outer ring 1 and the outer ring of the inner ring 2. An outer circular ring rubber pad 6 and an inner circular ring rubber pad 7 are respectively provided on the outer and inner rings of the dustproof sealing ring 5. The outer circular ring rubber pad 6 is in contact with the inner surface of the outer ring 1, and the inner circular ring rubber pad 7 is in contact with the outer surface of the inner ring 2.

[0020] Furthermore, multiple cylindrical rollers 4 are provided, and the multiple cylindrical rollers 4 are distributed in a ring array about the center of the ring cage 3.

[0021] The use of multiple cylindrical rollers 4 ensures the smooth rotation of the inner ring 2 within the bearing.

[0022] Furthermore, both sides of the top and bottom surfaces of the circular retainer 3 are provided with connecting studs 8, and the dustproof sealing ring 5 is provided with a through hole 9 corresponding to the connecting stud 8. One end of the connecting stud 8 passes through the through hole 9 and a locking nut 10 is threaded onto its outer wall.

[0023] Rotate the locking nut 10 to disengage it from the connecting stud 8, and remove the dustproof sealing ring 5 from the connecting stud 8. This will quickly complete the disassembly of the dustproof sealing ring 5, allowing for the inspection of the internal structure of the bearing.

[0024] Furthermore, the top surface of the outer ring 1, the top surface of the connecting stud 8, and the top surface of the inner ring 2 are on the same horizontal plane.

[0025] By setting the height of the top surface of the outer ring 1, the top surface of the connecting stud 8, and the top surface of the inner ring 2, the bearing can be placed horizontally as a whole, so as to ensure the stability of the bearing installation.

[0026] In use, this invention utilizes an outer ring 1, an inner ring 2, a circular ring retainer 3, and cylindrical rollers 4 to form the basic structure of the bearing. Two dustproof sealing rings, one above the other, provide dust protection for the internal structure of the bearing. An outer ring rubber pad 6 and an inner ring rubber pad 7 enhance the sealing performance of the dustproof sealing ring 5 between the outer ring 1 and the inner ring 2, improving the reliability of the dustproof sealing ring 5 in isolating external dust and impurities. Rotating the locking nut 10 disengages it from the connecting stud 8, allowing the dustproof sealing ring 5 to be quickly removed from the connecting stud 8. This facilitates the inspection and maintenance of the bearing's internal structure, ensuring the long-term stability of the bearing.

[0027] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
