Technical Field

[0001] This utility model belongs to the field of roller bearing technology, specifically a novel single-row roller bearing. Background Technology

[0002] Single-row roller bearings are one of the most widely used bearing types. The inner wall of the outer ring of a single-row roller bearing is usually provided with a limiting groove to limit the rolling elements. For cylindrical rolling elements, during the movement of the rolling elements inside the limiting groove, the two end faces of the rolling elements will slide against the side of the limiting groove. At the same time, sliding friction will also occur between the rolling elements and the cage. Sliding friction not only easily accelerates wear, but also generates a lot of heat, affecting the service life of the bearing. Therefore, this application proposes a novel single-row roller bearing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Depend on Figures 1 to 6 The present invention discloses a novel single-row roller bearing, comprising an outer ring 1, an inner ring 2, a cage 3, and a plurality of rolling elements 4. The inner ring 2 is located inside the outer ring 1, and the cage 3 and the rolling elements 4 are located between the outer ring 1 and the inner ring 2. The inner sidewall of the outer ring 1 is provided with an annular limiting groove 5 that matches the rolling elements 4. A plurality of auxiliary limiting components 1 6 are provided on both sides inside the annular limiting groove 5. A second auxiliary limiting component 2 7 that matches the rolling elements 4 is provided on both sides inside the cage 3.

[0026] The annular limiting groove 5 limits the rolling element 4, the auxiliary limiting component 1 6 can reduce the friction between the rolling element 4 and the outer ring 1, and the auxiliary limiting component 2 7 can reduce the friction between the rolling element 4 and the cage 3.

[0027] The auxiliary limiting component 6 consists of a ball sleeve 8 and a universal ball 9. The ball sleeve 8 is inserted into the inside of the annular limiting groove 5, and the universal ball 9 is rotatably connected to the inside of the ball sleeve 8.

[0028] The universal ball bearing 9 rotates inside the ball sleeve 8 and fits against both ends of the rolling element 4, preventing the two end faces of the rolling element 4 from sliding against the outer ring 1, thereby reducing wear and heat generation.

[0029] The auxiliary limiting component 2 7 consists of a ball sleeve 2 10, a universal ball 2 11, a limiting rod 12 and a spring 13. The limiting rod 12 is fixedly connected to the middle position of one end of the ball sleeve 2 10. Both the ball sleeve 2 10 and the limiting rod 12 are inserted into the inside of the retainer 3. The universal ball 2 11 is rotatably connected to the end of the ball sleeve 2 10 away from the limiting rod 12. The spring 13 is sleeved on the limiting rod 12.

[0030] The universal ball bearing 11 rotates inside the ball sleeve 10. The universal ball bearing 11 limits the two ends of the rolling element 4, so that the rolling element 4 is located in the middle position inside the mounting groove on the cage 3, avoiding sliding friction between the rolling element 4 and the cage 3. When installing and removing the rolling element 4, press the rolling element 4 with force to compress the spring 13, which effectively improves the convenience of installing and removing the rolling element 4 and the cage 3.

[0031] Both sides of the annular limiting groove 5 are provided with several insertion slots 14 that match the ball sleeve 8. The ball sleeve 8 is slidably connected to the inside of the insertion slots 14, which can limit the installation of the ball sleeve 8.

[0032] A protruding ring 15 is fixedly provided on the side of the ball sleeve 8 near the universal ball 9. A gap is formed between the protruding ring 15 and the inner wall of the annular limiting groove 5, which makes it easy to disassemble the ball sleeve 8 using tools.

[0033] The retainer 3 has several insertion slots 16 that match the ball sleeve 10 and the limiting rod 12. The ball sleeve 10 and the limiting rod 12 are slidably connected inside the insertion slots 16, which can limit the installation of the ball sleeve 10 and the limiting rod 12.

[0034] A positioning plate 17 is provided at the end of the limiting rod 12 away from the universal ball bearing 11. A threaded rod 18 is fixedly provided at one end of the positioning plate 17. The threaded rod 18 is threadedly connected to the limiting rod 12, which can limit the limiting rod 12 and improve the stability of the limiting rod 12.

[0036] In operation, the rolling elements are limited by the annular limiting groove. The auxiliary limiting component one, consisting of a ball sleeve and a universal ball, allows the two ends of the rolling elements to form rolling friction with the inner wall of the annular limiting groove, reducing sliding friction and thus reducing wear and heat generation. The auxiliary limiting component two, consisting of a ball sleeve, a universal ball, a limiting rod, and a spring, prevents sliding friction between the rolling elements and the cage, thus reducing wear and heat generation. The limiting rod is limited by the positioning plate and the threaded rod.
