[0002] Spherical roller bearings are bearings with drum-shaped rollers assembled between an inner ring with two raceways and an outer ring with a spherical raceway. Spherical roller bearings have two rows of rollers and mainly bear radial loads, but can also bear axial loads in any direction. Spherical roller bearings have a high radial load capacity and are particularly suitable for working under heavy loads or vibration loads.

[0003] After long-term use of spherical roller bearings, dust will enter between the cage and the inner and outer rings, and the rollers will also wear due to high-intensity work, thus affecting the normal operation of the bearings. At present, knocking, pushing and other methods are often used when disassembling or installing bearings. This method is not only time-consuming and labor-intensive, but also easily damages the bearings. Utility Model Content

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a spherical self-aligning roller bearing that is easy to disassemble, including an outer ring 1, slots 2 are opened on both sides of the outer ring 1, dust shields 3 are inserted into the outer ring 1 through the slots 2, a main retainer 4 is installed on the inner side of the outer ring 1, and plug holes 5 are opened on both sides of the main retainer 4. The plug hole 5 is L-shaped as a whole, and a slope plate 18 is connected to the plug hole 5. The elastic block 17 is engaged with the plug hole 5, and the main retainer 4 is inserted with a secondary retainer 6 through the plug hole 5. The secondary retainer 6 is The side is connected with an elastic block 17, and the side of the elastic block 17 away from the dust guard plate 3 is triangular in design. Through the slope plate 18 and the triangular inclined surface on one side of the elastic block 17, the elastic block 17 will be squeezed and deformed by the slope plate 18 when entering the socket 5. Therefore, when the elastic block 17 completely enters the socket 5, the elastic block 17 rebounds and fits with the socket 5, fixing the auxiliary retainer 6 on both sides of the main retainer 4, thereby completing the assembly and preventing the roller body 8 from falling off during rolling.

[0023] A mounting groove 7 is provided on the main retaining frame 4, and a roller body 8 is installed in the mounting groove 7. Elastic blocks 9 are connected to both sides of the mounting groove 7. Rolling bars 10 are rollingly installed on the elastic blocks 9. A sealing ring 12 is connected to the dust shield 3. An inner ring 11 is installed on the inner side of the main retaining frame 4 and the auxiliary retaining frame 6. Rolling grooves 20 are provided on both sides of the inner ring 11. The sealing ring 12 is embedded in the rolling groove 20. The gap between the dust shield 3 and the inner ring 11 is sealed by the sealing ring 12 to prevent dust from entering and prevent dust particles from wearing the roller body 8.

[0024] The dust shield 3 is connected to a plug-in board 13, and there are four plug-in boards 13 in total and they are symmetrical about the center of the dust shield 3. The plug-in board 13 is plugged into the slot 2, and the rolling bar 10 contacts both sides of the roller body 8. When the roller body 8 rolls, the rolling bar 10 will also rotate, thereby reducing the friction between the roller body 8 and the wall of the mounting groove 7.

[0025] A slide groove 14 is provided inside the plug board 13, and a spring 15 is connected inside the slide groove 14. A fixing block 16 is connected to one end of the spring 15. Fixing grooves 19 are provided on the inner walls on both sides of the slot 2. The side of the fixing block 16 away from the spring 15 is spherical in design, and the fixing block 16 is engaged with the fixing groove 19. Through the spherical surface on one side of the fixing block 16, the fixing block 16 can be flexibly and quickly pushed by the slot wall of the slot 2, thereby facilitating the staff to install and remove the dust shield 3.

[0026] The working principle of the utility model is:

[0027] The staff puts the roller body 8 into the installation groove 7. At this time, the roller body 8 will squeeze the elastic block 9 through the rolling bar 10, causing the elastic block 9 to deform. After the roller body 8 is completely installed in the installation groove 7, the elastic block 9 rebounds, so that the rolling bar 10 clamps the roller body 8 to prevent the roller body 8 from falling during installation. Then, the elastic block 17 is inserted into the socket 5. During insertion, the elastic block 17 is pushed and squeezed by the ramp plate 18, and then the elastic block 17 rebounds and fits into the socket 5. The auxiliary retainer 6 is fixed on both sides of the main retainer 4, and the staff then inserts the plug board 13 into the slot 2. As the plug board 13 is inserted, the slot 2 wall will push the fixing block 16 into the slide groove 14 to compress the spring 15. After the plug board 13 is fully inserted into the slot 2, the spring 15 rebounds and pushes the fixing block 16 into the fixing groove 19, fixing the dust shield 3 on the outer ring 1, thereby blocking the gap between the outer ring 1 and the inner ring 11 through the dust shield 3 and preventing dust particles from entering.
