Description

Technical Field

[0001] The utility model relates to the technical field of bearing rings, in particular to a high-sealing bearing ring. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are mainly composed of rings (outer ring and inner ring), balls and cages.

[0003] In order to prevent dust from entering the bearing and grease from leaking, sealing rings are often installed on the bearing rings. However, the sealing rings and the inner and outer rings of the bearing rings are generally tightly connected. When the sealing rings need to be removed to add grease or clean dust, it is often necessary to pry the sealing rings with external tools to remove them. This is inconvenient to use and lacks certain practicality. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] See also Figure 1-5 A high-sealing bearing ring comprises a main body component 1; the main body component 1 comprises an outer ring 11, an inner ring 12 is arranged inside the outer ring 11; a plurality of balls 13 are rotatably connected between the outer ring 11 and the inner ring 12; a disassembly component 2 is arranged on the outer ring 11, and the disassembly component 2 comprises: a sealing ring 21, arranged between the outer ring 11 and the inner ring 12, the outer wall of the sealing ring 21 is provided with anti-slip grooves, and a mounting groove is opened on the top; a fixing ring 22, fixedly connected to the inside of the mounting groove of the sealing ring 21; a toothed disc 23, slidably connected At the top of the fixing ring 22; a threaded rod 24, which passes through the fixing ring 22 and is threadedly connected to the fixing ring 22, and four of them are evenly arranged; a gear 25, one end of each of the threaded rods 24 is fixedly connected to a gear 25, and each of the gears 25 is meshed with the toothed disc 23; a limit block 26, one end of each of the threaded rods 24 is rotatably connected to the limit block 26; a limit groove 27, which is opened on the inner side of the outer ring 11, and four of them are evenly arranged; the length of the toothed disc 23 is greater than the length of the installation groove of the sealing ring 21; a positioning ring 4 is fixedly connected to the inner side of the outer ring 11.

[0029] When ready for use, the outer ring 11 is placed in the specified position, and the ball 13 rotates between the outer ring 11 and the inner ring 12. When the sealing ring 21 needs to be disassembled, the operator rotates the toothed disc 23 by hand, and the rotation of the toothed disc 23 drives the multiple gears 25 to rotate at the same time, and the rotation of the multiple gears 25 drives the multiple threaded rods 24 to rotate at the same time, so that the threaded rods 24 drive the limit blocks 26 to move toward the fixed ring 22, so that the multiple limit blocks 26 are simultaneously moved out of the limit grooves 27 on each side, and the limit on the sealing ring 21 is cancelled. Then the operator can directly remove the sealing ring 21 to add grease or clean dust. When installing the sealing ring 21, the operator places the sealing ring 21 between the outer ring 11 and the inner ring 12, aligns the limit blocks 26 with the limit grooves 27, and passes the sealing ring 2 1 The protective pattern on the surface prevents it from sliding. Then the operator can reversely twist the toothed disc 23 to drive the limit block 26 into the limit groove 27 to fix the sealing ring 21 without the help of tools, and the operation is simple, which improves the practicality of the device; the length of the toothed disc 23 is greater than the length of the installation groove of the sealing ring 21, so that the toothed disc 23 can always cover the installation groove at the top of the sealing ring 21 to prevent dust from entering the installation groove through the gap between the toothed disc 23 and the sealing ring 21, making it inconvenient for the operator to clean, thereby improving the stability of the device; the inner side of the outer ring 11 is fixedly connected with a positioning ring 4. When the operator installs the sealing ring 21, he only needs to press the sealing ring 21 against the positioning ring 4 to keep the limit block 26 at the same height as the limit groove 27, which is convenient for the operator to install, thereby improving the convenience of the device.

[0030] Embodiment 2

[0031] See also Figure 1-5 , based on the first embodiment, an auxiliary fixing function is added;

[0032] An auxiliary component 3 is provided on the outer ring 11, and the auxiliary component 3 includes: a bolt 31, which passes through the toothed disc 23 and is threadedly connected to the toothed disc 23; a limit plate 32, which is rotatably connected to the bottom end of the bolt 31; a movable plate 33, which is fixedly connected to the outer wall of the limit plate 32 and slidably connected to the inner wall of the sealing ring 21; a groove body 34, which is opened inside the mounting groove of the sealing ring 21, and the limit plate 32 is inserted into the groove body 34; a turntable 5 is fixedly connected to the top of the bolt 31; and a positioning line 6 is provided on the top surface of the outer ring 11.

[0033] After the operator has installed the sealing ring 21, he or she manually screws the bolt 31, and the bolt 31 rotates while approaching the sealing ring 21. Under the limit of the movable plate 33, the bolt 31 drives the limit plate 32 to move toward the sealing ring 21. The bolt 31 is continuously rotated to drive the limit plate 32 into the groove body 34, thereby limiting the toothed disc 23, and preventing the toothed disc 23 from automatically moving due to vibration when the bearing needs to be used on a device with severe shaking, thereby causing the sealing ring 21 to be loosely fixed and then fall off, thereby improving the practicability of the device; the bolt 31 A turntable 5 is fixedly connected to the top, and the operator can drive the bolt 31 to move by turning the turntable 5 by hand to prevent the top of the bolt 31 from being too small and inconvenient for the operator to twist it by hand, thereby improving the operator's work efficiency; a positioning line 6 is provided on the top surface of the outer ring 11, and when the operator installs the sealing ring 21, he only needs to align the limit block 26 with the positioning line 6 to align the angle of the limit block 26 with the limit groove 27, thereby preventing the sealing ring 21 from covering the limit groove 27 during installation, making it inconvenient for the operator to check the position of the limit groove 27, thereby improving the convenience of the device.
