[0012] Preferably, one end of the limiting rod contacts but is not fixed to the inner ring of the bearing.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) This device can not only limit multiple ball bearings simultaneously, but also facilitate the replacement of a single ball bearing, ensuring the accuracy of the ball bearing position and reducing the assembly difficulty of this device at the same time.

[0015] (2) This device fixes the limiting rod on the inner wall of the outer ring of the bearing, places the ball bearing inside the limiting rod, sets a limiting piece on the top of the ball bearing to be fixed to the limiting rod, and simultaneously sets an openable movable cover on the limiting piece.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: an aviation bearing with a limiting function, including a bearing outer ring 1 and a bearing inner ring 3. A limiting rod 4 is provided on the inner wall of the bearing outer ring 1, and one end of the limiting rod 4 contacts the bearing inner ring 3 without being fixed; this structure can ensure the normal rotation of the bearing inner ring 3. Multiple groups of limiting rods 4 are provided, with two in each group. A rolling ball 5 is provided inside the limiting rod 4, and limiting components 6 are provided at both ends of the rolling ball 5.

[0024] The limiting component 6 includes a limiting piece 61 provided between the bearing outer ring 1 and the bearing inner ring 3. A sleeve 65 is embedded in the opening side of the limiting piece 61. A anti-sway rod 69 and a movable spring 610 are fixedly connected inside the sleeve 65; this structure can limit the movable spring 610 by providing the anti-sway rod 69, thereby preventing the movable spring 610 from tilting. One end of the movable spring 610 is connected to a movable block 68, and the movable spring 610 is sleeved on the outer wall of the anti-sway rod 69; this structure provides a certain lifting space for the movable block 68 and the connecting block 64 on the top of the movable block 68 by providing the movable spring 610. A rotating shaft 67 is provided on the top of the movable block 68, and a connecting block 64 is connected to the top of the rotating shaft 67. A limiting plate 66 is fixedly connected to one side of the connecting block 64, and the limiting plate 66 is rotatably connected to the sleeve 65; this structure can rotate the connecting block 64 and the limiting plate 66 by providing the rotating shaft 67, and can control the contact and separation between the limiting plate 66 and the movable cover 63. The limiting piece 61 is located on the top of the limiting rod 4. A fixing screw 62 is inserted into the limiting piece 61, and one end of the fixing screw 62 is fixedly connected to the limiting rod 4. A pressing cover 2 is provided on the top of the limiting piece 61; this structure can fix the limiting piece 61 and the limiting rod 4 through the fixing screw 62. The limiting piece 61 is of an annular structure, and an opening is provided on the limiting piece 61. A movable cover 63 is hinged to the inner side of the opening. A groove is provided on the movable cover 63, and a limiting plate 66 is provided inside the groove; this structure can limit the movable cover 63 through the limiting plate 66, so that the movable cover 63 will not open randomly when closed. The movable cover 63 corresponds to the position of the rolling ball 5. A limiting plate 66 is provided on the top of the movable cover 63, and one side of the limiting plate 66 is rotatably connected to the limiting piece 61.

[0025] Working principle: When using the aviation bearing with a limit function, if it is necessary to replace a single ball 5, the gland 2 can be removed from between the bearing outer ring 1 and the bearing inner ring 3. Then, the movable cover 63 corresponding to the position of the ball 5 to be removed is opened. When opening, the connecting block 64 is pulled upward, so that the connecting block 64 drives the movable block 68 to move upward, and the movable spring 610 is in a stretched state, so that the limit plate 66 is separated from the inside of the movable cover 63. Then, the connecting block 64 is rotated, so that the connecting block 64 drives the connecting block 64 to rotate through the rotating shaft 67, so that the connecting block 64 is away from the movable cover 63. At this time, the movable cover 63 can be opened. After the movable cover 63 is opened, the ball 5 inside the limit rod 4 can be removed and replaced.
