Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a silent zero-type bearing with ultra-high speed and ultra-long life. Background Technology

[0002] Class 0 bearings typically refer to deep groove ball bearings (single-row rolling elements). They have a simple structure, low coefficient of friction, and are suitable for high-speed rotation. In bearings, ball bearings convert sliding friction into rolling friction by assembling spherical rolling elements (balls), significantly reducing the coefficient of friction. This makes mechanical equipment operate more smoothly and reduces energy loss. For example, in bicycles and various industrial machines, the presence of balls reduces the resistance to be overcome during operation, lowers power consumption, and improves transmission efficiency.

[0003] As usage time increases, the balls gradually wear down, resulting in decreased precision and increased clearance, leading to increased vibration and noise. This affects the operational accuracy and stability of the equipment. If the balls are not replaced in time, it will accelerate the damage to other components and shorten the overall lifespan of the equipment. Therefore, we offer a high-speed, long-life, silent zero-class bearing. Utility Model Content

[0004] The purpose of this invention is to provide a silent zero-class bearing with ultra-high speed and ultra-long life to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silent zero-class bearing with ultra-high speed and ultra-long life, comprising: an inner ring of the bearing;

[0006] The first bearing outer ring is fitted onto the outer wall of the bearing inner ring;

[0007] A second bearing outer ring fitted onto the outer wall of the first bearing outer ring;

[0008] An operating component is provided between the inner ring of the bearing and the outer ring of the second bearing; the operating component includes a fixing part fixedly connected between the outer ring of the first bearing and the outer ring of the second bearing, and an assembly part is provided below the fixing part.

[0009] Preferably, the fixing part includes a mounting ring fixedly connected to the inner back of the second bearing outer ring. The inner surface of the mounting ring is engaged between the two first bearing outer rings. Positioning rings are respectively provided on both sides of the mounting ring. The outer wall of the positioning ring is fixedly connected to the inner wall of the second bearing outer ring. A fixing groove is provided on one side of the positioning ring. A fixing rod is engaged on the inner surface of the fixing groove. The end of the fixing rod away from the fixing groove is hinged to the outer wall of the ring rod through a mounting block. The side of the mounting block away from the fixing rod is fixedly connected to the inner wall of the annular connecting groove. The annular connecting groove is opened on the outer wall of the first bearing outer ring. The positioning ring is engaged on the inner surface of the annular connecting groove.

[0010] Preferably, the assembly part includes annular mounting grooves formed on both sides of the outer wall of the bearing inner ring. Annular mounting blocks are engaged on the inner surface of the annular mounting grooves. A first annular assembly groove is formed on one side of the annular mounting block. A retainer is provided on the inner surface of the first annular assembly groove. The side of the retainer away from the first annular assembly groove is provided on the inner surface of a second annular assembly groove. The second annular assembly groove is formed on one side of the convex end of the bearing inner ring. A ball is rotatably connected inside the retainer. A lower sealing ring is provided on the side of the annular mounting block. A sealing ring is engaged on the inner surface of the lower sealing ring. An upper sealing ring is engaged on the lower surface of the sealing ring.

[0011] Preferably, the number of the first bearing outer rings is set to two, and the two first bearing outer rings are respectively fitted on both sides of the outer wall of the bearing inner ring, which facilitates the assembly and disassembly of the first bearing outer rings and the replacement of the balls.

[0012] Preferably, the inner wall of the mounting ring is in contact with the convex end surface of the bearing inner ring to ensure relative movement between the bearing inner ring and the first bearing outer ring and the second bearing outer ring.

[0013] Preferably, the upper and lower surfaces of the balls are rotatably connected to the raceways provided between the outer wall of the inner ring of the bearing and the inner wall of the outer ring of the first bearing. The balls reduce friction, transforming the sliding friction between the inner ring of the bearing and the outer rings of the first and second bearings into rolling friction, which greatly reduces frictional resistance and thus increases the rotational speed.

[0014] Preferably, the lower sealing ring and the upper sealing ring are symmetrically arranged, and the lower sealing ring and the upper sealing ring are respectively engaged with the upper and lower surfaces of the sealing ring to further tighten and position the sealing ring, so that the sealing ring and the bearing components fit more tightly, reduce the possibility of leakage, and thus extend the service life of the bearing.

[0015] Compared with the prior art, this utility model provides a silent zero-class bearing with ultra-high speed and ultra-long life, which has the following beneficial effects:

[0016] 1. This ultra-high speed, ultra-long life silent zero-class bearing initially positions the second bearing outer ring and the first bearing outer ring by engaging the mounting ring on the inner wall of the second bearing outer ring with the inner end of the two first bearing outer rings. Simultaneously, the positioning ring on the inner wall of the second bearing outer ring engages with the inner surface of the annular connecting groove, and the outer end of the fixing rod is pressed downward. When the outer end of the fixing rod aligns with the fixing groove, the fixing rod engages with the inner surface of the fixing groove, thus completing the assembly of the second bearing outer ring and the first bearing outer ring. This also facilitates separation for subsequent replacement of the balls.

[0017] 2. This ultra-high speed, ultra-long life silent zero-class bearing uses the upper and lower surfaces of the balls to rotate and connect within the raceways between the inner ring of the bearing and the outer wall of the first bearing. The balls reduce friction, transforming the sliding friction between the inner ring and the outer rings of the first and second bearings into rolling friction, significantly reducing frictional resistance and thus increasing speed. Furthermore, the lower and upper sealing rings engage with the upper and lower surfaces of the sealing ring, further securing and positioning it, ensuring a tighter fit between the sealing ring and the bearing components, reducing the possibility of leakage, and extending the bearing's service life.

[0027] Example 1: The ultra-high speed, ultra-long life, silent zero-class bearing provided by this utility model, such as... Figures 1 to 6 As shown: A silent zero-class bearing with ultra-high speed and ultra-long life, comprising: bearing inner ring 1;

[0028] The first bearing outer ring 2 is fitted onto the outer wall of the bearing inner ring 1;

[0029] The second bearing outer ring 3 is fitted onto the outer wall of the first bearing outer ring 2;

[0030] An operating component 4 is provided between the inner ring 1 of the bearing and the outer ring 3 of the second bearing; the operating component 4 includes a fixing part 41 fixedly connected between the outer ring 2 of the first bearing and the outer ring 3 of the second bearing, and an assembly part 42 is provided below the fixing part 41.

[0031] The fixing part 41 includes a mounting ring 411 fixedly connected to the inner back of the second bearing outer ring 3. The inner surface of the mounting ring 411 is engaged between the two first bearing outer rings 2. Positioning rings 412 are respectively provided on both sides of the mounting ring 411. The outer wall of the positioning ring 412 is fixedly connected to the inner wall of the second bearing outer ring 3. A fixing groove 417 is provided on one side of the positioning ring 412. A fixing rod 416 is engaged on the inner surface of the fixing groove 417. The end of the fixing rod 416 away from the fixing groove 417 is hinged to the outer wall of the annular rod 414 through a mounting block 415. The side of the mounting block 415 away from the fixing rod 416 is fixedly connected to the inner wall of the annular connecting groove 413. The annular connecting groove 413 is opened on the outer wall of the first bearing outer ring 2. The positioning ring 412 is engaged on the inner surface of the annular connecting groove 413.

[0032] In this embodiment, the number of first bearing outer rings 2 is set to two. The two first bearing outer rings 2 are respectively fitted on both sides of the outer wall of the bearing inner ring 1, which facilitates the assembly and disassembly of the first bearing outer rings 2 and the replacement of the ball bearings 426.

[0033] Furthermore, the inner wall of the mounting ring 411 is configured to contact the convex end surface of the bearing inner ring 1 to ensure relative movement between the bearing inner ring 1 and the first bearing outer ring 2 and the second bearing outer ring 3.

[0034] Example 2: Based on Example 1, the ultra-high speed, ultra-long life, silent zero-class bearing provided by this utility model, such as... Figures 1 to 6 As shown: The assembly part 42 includes annular mounting grooves 421 formed on both sides of the outer wall of the inner ring 1 of the bearing. Annular mounting blocks 422 are engaged on the inner surface of the annular mounting grooves 421. A first annular assembly groove 423 is formed on one side of the annular mounting block 422. A retainer 424 is provided on the inner surface of the first annular assembly groove 423. The side of the retainer 424 away from the first annular assembly groove 423 is provided on the inner surface of the second annular assembly groove 425. The second annular assembly groove 425 is formed on one side of the protruding end of the inner ring 1 of the bearing. A ball 426 is rotatably connected inside the retainer 424. A lower sealing ring 427 is provided on the side of the annular mounting block 422. A sealing ring 428 is engaged on the inner surface of the lower sealing ring 427. An upper sealing ring 429 is engaged on the lower surface of the sealing ring 428.

[0035] In this embodiment, the upper and lower surfaces of the ball 426 are rotatably connected to the raceways provided between the outer wall of the inner ring 1 of the bearing and the inner wall of the outer ring 2 of the first bearing. The ball 426 reduces friction, transforming the sliding friction between the inner ring 1 of the bearing and the outer rings 2 and 3 of the first and second bearings into rolling friction, which greatly reduces frictional resistance and thus increases the rotational speed.

[0036] Furthermore, the lower sealing ring 427 and the upper sealing ring 429 are symmetrically arranged. The lower sealing ring 427 and the upper sealing ring 429 are respectively engaged with the upper and lower surfaces of the sealing ring 428, which further tightens and positions the sealing ring 428, making the fit between the sealing ring 428 and the bearing component tighter, reducing the possibility of leakage, and thus extending the service life of the bearing.

[0037] In actual operation, when this device is used, the mounting ring 411 on the inner wall of the second bearing outer ring 3 is snapped onto the inner end outer wall of the two first bearing outer rings 2, thereby initially positioning the second bearing outer ring 3 and the first bearing outer ring 2. At the same time, the positioning ring 412 on the inner wall of the second bearing outer ring 3 is snapped onto the inner surface of the annular connecting groove 413. Meanwhile, the outer end of the fixing rod 416 is pressed downward. When the outer end of the fixing rod 416 corresponds to the position of the fixing groove 417, the fixing rod 416 is snapped onto the inner surface of the fixing groove 417, thereby completing the assembly of the second bearing outer ring 3 and the first bearing outer ring 2. This also facilitates the separation of the first bearing outer ring 2 and the second bearing outer ring 3, so as to facilitate the subsequent replacement of the ball bearing 426.

[0038] The upper and lower surfaces of the ball bearing 426 are rotatably connected to the raceways provided between the outer wall of the inner ring 1 and the inner wall of the outer ring 2 of the first bearing. The ball bearing 426 reduces friction, transforming the sliding friction between the inner ring 1 and the outer rings 2 and 3 into rolling friction, greatly reducing frictional resistance and thus increasing the rotational speed. The lower sealing ring 427 and the upper sealing ring 429 are respectively engaged with the upper and lower surfaces of the sealing ring 428, further securing and positioning the sealing ring 428, making the fit between the sealing ring 428 and the bearing components tighter, reducing the possibility of leakage, and thus extending the service life of the bearing.
