Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a deep groove ball bearing with a sealing structure. Background Technology

[0002] In many mechanical transmission systems, bearings play an indispensable supporting and rotating role as key components. Among them, deep groove ball bearings are widely used due to their advantages such as compact structure, low coefficient of friction, and high limiting speed.

[0003] However, existing deep groove ball bearings generally have exposed balls and lack an effective sealing structure. The exposed balls make the bearings extremely susceptible to the intrusion of external impurities. In industrial production environments, tiny particles such as dust, metal shavings, and sand are ubiquitous. These impurities can easily enter the bearing and come into direct contact with the balls, inner ring, outer ring, and cage. As the bearing continues to operate, these impurity particles become embedded between the raceway and the balls, exacerbating friction and wear. This causes scratches and pits to appear on the raceway surface, and the sphericity of the balls is gradually damaged. Consequently, the bearing's rotational accuracy and stability are severely affected, and its service life is significantly shortened. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a deep groove ball bearing with a sealing structure, addressing the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a deep groove ball bearing with a sealing structure, including an inner ring and an outer ring, wherein the inner ring is disposed inside the outer ring, and balls are disposed between the outer ring and the inner ring. Sealing mechanisms are provided at the top and bottom of both the inner ring and the outer ring. The sealing mechanism includes a first groove, a sliding plate, a retaining rod, a second groove, and a sealing ring. The first groove is formed on the outer wall of the outer ring, the sliding plate is slidably connected inside the first groove, the retaining rod is fixedly connected to one side of the sliding plate, and one end is inserted into the inside of the second groove. The second groove is formed on the outer wall of the sealing ring, and the sealing ring is disposed between the outer ring and the inner ring.

[0006] Preferably, one end of the locking rod extends through the inner wall of the first groove to the inside of the second groove, the locking rod is slidably connected to the outer ring, a limiting rod is fixedly connected inside the first groove, and the limiting rod passes through the sliding piece and is slidably connected to the sliding piece.

[0007] Preferably, a spring is sleeved on the outer wall of the limiting rod, and the two ends of the spring are fixedly connected to the outer wall of the slide and the inner wall of the groove, respectively.

[0008] Preferably, the top and bottom of the inner ring are provided with embedded grooves, and the outer wall of the sealing ring is fixedly connected to a circular ring, which is rotatably connected inside the embedded groove.

[0009] Preferably, the inner wall of the first groove is provided with a third groove, and a second limiting rod is slidably connected inside the third groove. The slide plate is provided with a hole, and the second limiting rod passes through the hole and is slidably connected to the hole.

[0010] Preferably, a spring two is provided inside the groove three, and the two ends of the spring two are fixedly connected to the outer wall of the limiting rod two and the inner wall of the groove three, respectively.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. This deep groove ball bearing with a sealing structure allows the sliding plate to be moved, causing the sliding plate to move the locking rod away from the second groove. After the rod is disengaged, the sealing ring is released, making it easy to disassemble. Before using the bearing, the sealing ring is installed between the outer and inner rings, and the locking rod is inserted into the second groove to fix the sealing ring. This prevents dust and other impurities from entering the bearing and improves the bearing's service life.

[0013] 2. This deep groove ball bearing with a sealing structure improves the ease of disassembly and assembly of the sealing ring by first moving the slide to disengage the locking rod from the groove 2 when disassembling the sealing ring. At the same time, the limiting rod 2 disengages from the hole. Then, the limiting rod 2 is pressed to misalign the limiting rod 2 with the hole. The limiting rod 2 abuts against the slide to stop the slide from moving, thereby improving the ease of disassembly and assembly of the sealing ring. Attached Figure Description

[0022] Please see Figure 1-3 One embodiment of this utility model is: a deep groove ball bearing with a sealing structure, including an inner ring 2 and an outer ring 1. The inner ring 2 is disposed inside the outer ring 1. Balls 3 are disposed between the outer ring 1 and the inner ring 2. Sealing mechanisms 4 are provided at the top and bottom of both the inner ring 2 and the outer ring 1. The sealing mechanism 4 includes a first groove 41, a sliding plate 43, a retaining rod 45, a second groove 46, and a sealing ring 47. The first groove 41 is formed on the outer wall of the outer ring 1. The sliding plate 43 is slidably connected inside the first groove 41. The retaining rod 45 is fixedly connected to one side of the sliding plate 43, and one end is inserted into the second groove 46. The second groove 46 is formed on the outer wall of the sealing ring 47. The sealing ring 47 is located between the outer ring 1 and the inner ring 2. One end of the locking rod 45 extends through the inner wall of the first groove 41 to the inside of the second groove 46. The locking rod 45 is slidably connected to the outer ring 1.
