Description

Technical Field

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

[0002] Bearings are a key component used to support mechanical rotating elements. They are widely used in various equipment and mechanical systems. The main function of bearings is to reduce the friction of mechanical elements and make them rotate more smoothly. The main body of the bearing usually includes an inner ring, an outer ring, rolling elements, a cage and a sealing cover. The function of the sealing cover is to effectively shield external contaminants and prevent grease leakage. It can help protect the inside of the bearing from the invasion of external impurities and contaminants, thereby improving the performance and life of the bearing.

[0003] However, although the existing dustproof sealed bearings have good sealing ability, dustproof ability and heat dissipation effect, they need to use tools such as screwdrivers to disassemble the sealing cover. Tools such as screwdrivers are easy to damage the sealing cover, causing the sealing cover to deform. After the deformed sealing cover is installed and docked with the outer ring again, it is easy to fall off, thereby affecting the dustproof sealing effect of the sealing cover on the bearing.

[0033] See also Figure 1 and Figure 3 A receiving groove 5 is provided inside the outer ring 1, and a locking component is provided inside the receiving groove 5.

[0034] The principle of being able to quickly remove the sealing cover 14 is: after releasing the lock of the locking assembly on the sealing cover 14, the compressed elastomer 11 will push the sealing cover 14 to move outward through the top column 12, so that the sealing cover 14 pops outward and separates from the outer ring 1, which is conducive to improving the convenience of disassembling the sealing cover 14.

[0035] See also Figure 1 and Figure 3 A rolling body 2 is arranged on the inner side of the outer ring 1, and a retaining frame 3 is connected to the outer surface of the rolling body 2. An inner ring 4 is arranged inside the outer ring 1. A rubber cover 7 is arranged above the receiving groove 5. The rubber cover 7 has a rectangular structure when viewed from above, and the thickness of the rubber cover 7 is less than the depth of the receiving groove 5.

[0036] It is worth mentioning that the rubber cover 7 can protect the storage groove 5 to prevent moisture and dust from entering the interior of the outer ring 1 through the storage groove 5, and the rectangular structure of the rubber cover 7 is easy to pull out.

[0037] See also Figure 1 and Figure 3 The outer ring 1 is connected to sealing covers 14 on both sides, and a slot 15 is provided on one side of the sealing cover 14. The surface of the outer ring 1 is provided with a convex strip 13, which is engaged with the slot 15. The slot 15 is an annular structure when viewed from above.

[0038] It should be noted that the engagement connection between the protruding strip 13 and the engaging groove 15 can enable the sealing cover 14 to be initially and quickly connected to the outer ring 1 , and ensure that the docking block 16 is inserted into the interior of the receiving groove 5 .

[0039] See also Figure 1 and Figure 3 The locking assembly includes an adjusting rod 6, a reset spring 8 and a latch 9. One end of the latch 9 is connected to the reset spring 8, and the other end of the reset spring 8 is fixedly connected to the receiving groove 5. The upper surface of the latch 9 is fixedly connected to the adjusting rod 6. The latch 9 forms a telescopic structure inside the receiving groove 5 through the reset spring 8, and the adjusting rod 6 is an inverted "Z"-shaped structure.

[0040] The principle of locking the sealing cover 14 is as follows: pull the adjusting rod 6 to make the latch 9 move to the outermost side inside the receiving groove 5, place the sealing cover 14 on the outer side of the outer ring 1, press the sealing cover 14, so that the convex strip 13 on one side of the outer ring 1 is engaged with the slot 15 on one side of the sealing cover 14, and at the same time, the docking block 16 on one side of the sealing cover 14 is inserted into the interior of the receiving groove 5, and then release the adjusting rod 6, and the reset spring 8 pushes the latch 9 to reset, so that the latch 9 is accurately inserted into the positioning hole 17 opened inside the docking block 16, thereby locking the sealing cover 14 and the outer ring 1, which is beneficial to prevent the sealing cover 14 and the outer ring 1 from falling off during the use of the bearing.

The top columns 12 are symmetrically distributed about the longitudinal center line of the outer ring 1. The top columns 12 and the sealing cover 14 fit each other.

[0042] It is worth mentioning that after the lock between the sealing cover 14 and the outer ring 1 is released, the compressed elastomer 11 will push the top column 12 to move, so that the top column 12 pushes the sealing cover 14 to move outward, and the sealing cover 14 will pop outward and separate from the outer ring 1. The sealing cover 14 and the outer ring 1 can be quickly disassembled without using tools, which helps to avoid damage to the sealing cover 14 caused by the use of disassembly tools.

[0043] See also Figure 1 and Figure 3A docking block 16 is fixedly connected to one side of the sealing cover 14, and a positioning hole 17 is opened inside the docking block 16.

The depth of the positioning hole 17 is less than the length of the pin 9, and the diameter of the pin 9 is less than the diameter of the positioning hole 17.

[0044] The function of the latch 9 is: the position of the latch 9 can be adjusted by the adjusting rod 6. The adjusting rod 6 is pulled to make the latch 9 move to the outermost side, and after pressing the sealing cover 14 to make it fit tightly with the outer ring 1, the adjusting rod 6 is loosened, and the reset spring 8 pushes the latch 9 to reset, so that the latch 9 is accurately inserted into the positioning hole 17 opened inside the docking block 16, thereby locking the sealing cover 14 and the outer ring 1. Similarly, the adjusting rod 6 is pulled again to make the latch 9 move to the outermost side, so that the latch 9 is separated from the positioning hole 17 opened inside the docking block 16, and the sealing cover 14 can be unlocked.
