[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-5A bearing which is easy to assemble comprises an inner liner ring 1, an outer liner ring 5 and rollers 4. The top of the inner liner ring 1 is provided with a plurality of grooves 2 at equal intervals, and a roller 4 is movably inserted in the interior of each groove 2. The outer liner ring 5 is sleeved on the outer wall of the inner liner ring 1. The bottom of the outer liner ring 5 is provided with a first annular groove 6, and the inner liner ring 1 is rotatably connected to the first annular groove 6. The inner top of the first annular groove 6 is provided with a second annular groove 7, and a plurality of rollers 4 are movably connected to the inner wall of the second annular groove 7. A through groove 8 is provided through the inner top of the second annular groove 7, and the top of the inner liner ring 1 extends out of the outer liner ring 5 through the through groove 8, and a retaining ring 9 is sleeved on one end of the inner liner ring 1 passing through the through groove 8.

[0020] Preferably, a first chamfer 3 is provided on the inner top wall of each groove 2. The arc-shaped first chamfer 3 can effectively increase the diameter of the inner top of the groove 2, making it easier for the roller 4 to be inserted into the groove 2.

[0021] Preferably, a plurality of locking bolts 10 are inserted at equal intervals on the outer wall of the retaining ring 9 , and the locking bolts 10 pass through one end of the retaining ring 9 and are threadedly connected to the inner liner 1 , so that the locking bolts 10 can connect the retaining ring 9 to the inner liner 1 .

[0022] Preferably, the inner liner 1 passes through the outer wall of one end of the through groove 8 and is fixedly connected to a limiting guide block 11, and a corresponding limiting groove 12 is opened on the side wall of the inner circle side of the retaining ring 9 corresponding to the limiting guide block 11, and the limiting guide block 11 is inserted into the inside of the limiting groove 12. When the limiting guide block 11 is aligned with the limiting groove 12, the locking bolt 10 can be passed through one end of the retaining ring 9 and aligned with the screw hole on the inner liner 1, which can make the installation of the retaining ring 9 more convenient.

[0023] Preferably, a second chamfer 13 is provided on the side wall of the inner circular side of the retaining ring 9. The arc-shaped second chamfer 13 can effectively increase the diameter of the inner bottom and inner top openings of the retaining ring 9, so that the retaining ring 9 can be more conveniently sleeved onto the outer wall of the inner liner 1.

[0024] Working principle: When in use, multiple rollers 4 are placed in the groove 2 on the inner liner 1 in sequence, and part of the outer wall of the roller 4 extends out of the groove 2. Then the outer liner 5 is sleeved on the outer wall of the inner liner 1. The first annular groove 6 inside the outer liner 5 contacts the outer wall of the inner liner 1, and the second annular groove 7 inside the outer liner contacts the position where the roller 4 extends out of the groove 2. Finally, the snap ring 9 is sleeved on the outer wall of the inner liner 1 passing through one end of the outer liner 5.

[0025] The limiting groove 12 on the clamping ring 9 is aligned with the limiting guide block 11 on the inner liner 1, so that the locking bolt 10 of the clamping ring 9 can be quickly aligned and inserted into the screw hole on the inner liner 1.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
