Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The daily maintenance and care of bearings include lubrication, cleaning, installation and disassembly, operation monitoring, storage and protection.

[0003] A patent search revealed a new type of stacked sealed bearing with publication number CN217682818U. The new type of stacked sealed bearing is equipped with ball grooves for connecting balls to the inner ring, and a fixed connection between the fixed part and the split part is achieved through a screw, thereby achieving a rotational connection between the outer ring and the inner ring through multiple sets of balls and semi-annular grooves. The new type of stacked sealed bearing has a simple structure and is easy to assemble and disassemble. The inner ring can be quickly removed by disassembling the split parts, and the connection is highly stable and the transmission effect is good. Although the above-mentioned comparative document adopts a quick-release design, the bearing needs to be completely disassembled for filling with lubricating oil, and there is still a certain inconvenience in its use.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , including: a bearing inner sleeve 1, a bearing ball 2 arranged on the outer wall of the bearing inner sleeve 1, an upper sealing plate 3 arranged on the top of the bearing inner sleeve 1, and a bearing outer sleeve 9 arranged on the bottom of the bearing inner sleeve 1. During assembly, the bearing outer sleeve 9 is placed at the bottom, and then the bearing inner sleeve 1 is placed on the inner side of the bearing outer sleeve 9, and then the upper sealing plate 3 is covered on the top of the bearing inner sleeve 1.

[0025] The sealing limit block 4 is fixed to the lower end of the upper sealing plate 3; the upper part of the bearing sleeve 9 is provided with a retaining groove portion 10 for combining with the lower end of the sealing limit block 4. When the upper sealing plate 3 is combined with the upper part of the bearing inner sleeve 1, the annular downwardly protruding sealing limit block 4 enters the retaining groove portion 10. Finally, after the upper sealing plate 3 is fitted with the upper wall of the bearing inner sleeve 1, the bottom of the sealing limit block 4 is fitted with the bottom of the retaining groove portion 10. After the combination is completed, the bearing inner sleeve 1, the sealing limit block 4 and the bearing sleeve 9 have a horizontal intersection position, and a limiting transverse groove 5 is opened at this position, so that the limiting transverse groove 5 can pass through the bearing sleeve 9, the sealing limit block 4 and the bearing inner sleeve 1, and then the limiting transverse insertion rod 12 can be horizontally inserted into the groove of the limiting transverse groove 5. The limiting transverse insertion rod 12 is rectangular and intersects with the limiting transverse insertion rod 12. The slotted adaption of the positioning transverse groove 5 allows the positioning transverse insertion rod 12 to eventually extend into the bearing inner sleeve 1 along the groove of the positioning transverse groove 5. The positioning transverse insertion rod 12 is inserted into the groove of the positioning transverse groove 5. The surfaces of the bearing inner sleeve 1 and the upper sealing plate 3 are provided with a positioning screw hole portion 6. The positioning screw 7 is screwed into the groove of the positioning screw hole portion 6. The surface of the positioning transverse insertion rod 12 is provided with a screw hole that allows the positioning screw 7 to be screwed in. After the positioning transverse insertion rod 12 is completely immersed in the groove of the positioning transverse groove 5, the screw hole on the surface of the positioning transverse insertion rod 12 is longitudinally aligned with the positioning screw hole portion 6. After the positioning screw 7 is screwed into the interior of the positioning screw hole portion 6, the positioning screw 7 can also be combined with the screw hole at the positioning transverse insertion rod 12, and finally the positioning transverse insertion rod 12 is restricted in the groove of the positioning transverse groove 5, thereby completing the bearing inner sleeve 1. The upper sealing plate 3 and the bearing outer sleeve 9 are combined. The cross-section of the sealing limit block 4 and the upper sealing plate 3 is an L-shaped structure. The upper sealing plate 3 covers the top of the bearing inner sleeve 1, so that the bearing inner sleeve 1 is restricted between the upper sealing plate 3 and the bearing outer sleeve 9 to maintain stability. The contact part of the sealing limit block 4 and the bearing outer sleeve 9 with the bearing ball 2 is an arc-shaped design that matches the shape of the bearing ball 2. After assembly is completed, the arc-shaped design of the sealing limit block 4 and the bearing outer sleeve 9 surrounds the outside of the bearing ball 2, providing space for the bearing ball 2 to roll.

[0026] An oil drain groove 8 is provided between the bearing inner sleeve 1 and the sealing limit block 4. An oil drain cavity 14 is provided inside the limit cross rod 12, and an oil drain port 13 communicating with the oil drain cavity 14 is provided on the surface of the limit cross rod 12. A plugging portion 15 is threadedly connected to the end of the limit cross rod 12. When the bearing balls 2 are filled with lubricating oil at a later stage, the plugging portion 15 can be removed from the threaded opening at the end of the limit cross rod 12, and then the lubricating oil can be injected along the threaded opening of the limit cross rod 12, so that the lubricating oil flows along the cavity of the oil drain cavity 14 to the oil drain port 13, and then falls from the oil drain port 13 into the oil drain groove 8, so that the lubricating oil in the oil drain groove 8 and the bearing balls 2 can be lubricated together.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
