Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a deep groove ball bearing. Background Art

[0002] Bearings are an important component used for the rotational support of mechanical bodies and can be seen everywhere in our lives and work. In order to adapt to different working environments, there are many types of bearings. Common bearings usually include an outer ring, an inner ring, several rolling elements and a cage. A raceway for accommodating several rollers is provided between the outer ring and the inner ring. The cage is used to form a spacing and guide for the several rollers. Deep groove ball bearings refer to bearings in which the rolling elements are ball-shaped and the raceway is formed by the recesses in the outer ring and the inner ring, forming a bearing structure that can provide radial and axial rotational support. It has the characteristics of simple structure and the widest application.

[0003] When the existing deep groove ball bearings are in use, dust will enter the deep groove ball bearings and affect the lubricating effect of the lubricating oil, causing damage to the balls and the bearings. In order to prevent dust from entering the deep groove ball bearings, rubber sealing rings are usually installed on the deep groove ball bearings. The rubber sealing rings will age after long-term use. The sealing effect of the aged rubber sealing rings is reduced and the rubber sealing rings need to be replaced. The rubber sealing rings are usually stuck in the rubber pad fixing grooves to achieve the sealing effect. When removing the rubber sealing rings, the staff need to take off the gloves they wear during work and buckle the rubber sealing rings. This will cause the staff's hands to be stuck with sticky substances such as lubricating oil, which is difficult to clean. In addition, when the hands are stained with sticky substances such as lubricating oil, it is inconvenient to install the rubber sealing rings, affecting the use of the deep groove ball bearings.

The first round rod 5 is rotatably mounted on the inner wall of the mounting groove 4. The outer surface of the first round rod 5 is rotatably mounted with a rotating plate 7. The left and right surfaces of the rotating plate 7 are both provided with rectangular grooves 8. Rectangular plates 9 are slidably mounted inside the two rectangular grooves 8. Two mounting plates 10 are fixedly mounted on the opposite ends of the two rectangular plates 9. The corresponding surfaces of the two front mounting plates 10 and the two rear mounting plates 10 are fixedly mounted with a second round rod 11. The push rod 6 is rotatably mounted on the outer surface of the second round rod 11 on the left, and the upper end of the push rod 6 slides and extends to the inside of the rubber pad fixing groove on the outer ring 2.

[0026] Furthermore, the ejection mechanism also includes a push rod 12 and a bolt 13. The push rod 12 is rotatably mounted on the outer surface of the second round rod 11 on the right side. A threaded hole 14 is provided on the upper surface of the outer ring 2 at a position corresponding to the mounting groove 4. The bolt 13 is rotatably mounted inside the threaded hole 14. The upper end of the push rod 12 slides and extends into the inside of the threaded hole 14, and the push rod 12 contacts the lower surface of the bolt 13.

[0027] Furthermore, by rotating the two bolts 13, the two push rods 12 can be moved downward, so that the rotating plate 7 cooperates with the rectangular plate 9 and the second round rod 11 to push the push rod 6 upward, so that the push rod 6 pushes the rubber sealing ring 15 inside the rubber pad fixing groove, so that the two ends of the rubber sealing ring 15 are tilted. The staff can remove the rubber sealing ring 15 while wearing gloves, preventing a large amount of lubricating oil from getting on the staff's hands when removing the rubber sealing ring 15, so that the staff can replace the rubber sealing ring 15 more conveniently, thereby improving the staff's work efficiency and thus improving the use efficiency of the deep groove ball bearing.

[0028] Furthermore, a rubber sealing ring 15 is slidably inserted into the inner wall of the rubber pad fixing groove of the outer ring 2 .

[0029] Furthermore, a spring 16 is fixedly installed on the inner wall of the installation groove 4 at a position corresponding to the push rod 12 , and the spring 16 is sleeved on the outer surface of the push rod 12 .

[0030] Furthermore, a circular plate 17 is fixedly mounted on the lower end of the outer surface of the push rod 12, and the spring 16 is fixedly connected to the circular plate 17.

[0031] Furthermore, there are two ejection mechanisms, which are respectively arranged inside the two installation slots 4 , and are installed in a left-right mirror image manner.

[0032] Working principle: When the bearing is used for a long time and the rubber sealing ring 15 needs to be replaced, the two bolts 13 can be rotated, and the two bolts 13 move downward in the corresponding threaded holes 14, pushing the two push rods 12 downward, and the circular plates 17 fixedly installed on the two push rods 12 move downward, so that the two springs 16 are stretched, and the two push rods 12 move downward to push the second round rod 11 connected to it for rotation downward, and the second round rod 11 drives the mounting plate 10 to move downward, and the mounting plate 10 drives the rectangular plate 9 fixedly connected to it to move downward, and the rectangular plate 9 drives one end of the rotating plate 7 to move downward, so that the rotating plate 7 rotates with the first round rod 5 as the center of the circle, and while the rotating plate 7 moves downward, the rectangular plate 9 slides on the inner wall of the rectangular groove 8, and the other end of the rotating plate 7 The second end is tilted, driving the rectangular plate 9 and the mounting plate 10 and the second round rod 11 at the other end to move upward, so that the push rod 6 moves synchronously, and the upper end of the push rod 6 enters the rubber pad fixing groove on the outer ring 2, and pushes out the two ends of the rubber sealing ring 15. At this time, the staff can remove the rubber sealing ring 15 with gloves. After removal, the two bolts 13 are rotated in the opposite direction. The two bolts 13 no longer apply pressure to the two push rods 12, so that the pressure on the two springs 16 disappears. The two springs 16 pull the two circular plates 17 to make the two push rods 12 fixedly connected to the two circular plates 17 move upward, thereby driving the rotating plate 7 to restore to a horizontal position, so that the two push rods 6 leave the rubber pad fixing groove, and then the rubber sealing ring 15 can be replaced.
