[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-4 A welded sealed self-lubricating sleeve comprises a sleeve body 1, a flange ring 2 is welded at one end of the sleeve body 1, an oil storage box 3 is arranged on one side of the flange ring 2 corresponding to the sleeve body 1, blocking rings 4 are welded at both ends of the sleeve body 1, and a twist cap 5 is arranged at the bottom of the sleeve body 1.

[0024] It should be noted that the sleeve 1 can be fixed to the output section of the rotating shaft through the flange ring 2 .

[0025] Furthermore, an upper oil groove 6 is provided at the top of the inner wall of the sleeve 1, a lower oil groove 7 is provided at the bottom of the inner wall of the sleeve 1 corresponding to the upper oil groove 6, an annular groove 8 is provided on the inner wall of the sleeve 1, and limiting grooves 11 matching the blocking ring 4 are provided at both ends of the inner wall of the sleeve 1.

[0026] It should be noted that the upper oil groove 6 and the lower oil groove 7 are longitudinally connected to the annular groove 8 so that the lubricating oil can be evenly distributed on the inner wall of the sleeve body 1 .

[0027] Furthermore, one side of the oil storage box 3 is bonded to the flange ring 2 by glue, the top of the oil storage box 3 is threadedly connected to a box cover 10, the bottom of the oil storage box 3 is fixedly connected to an oil outlet pipe 9, and the oil outlet pipe 9 passes through the inner wall of the sleeve body 1 and is connected to the upper oil groove 6.

[0028] It should be noted that the oil storage box 3 needs to use a transparent material so that the amount of lubricating oil in the sleeve body 1 can be judged by observing the oil storage box 3 . The box cover 10 can be opened by turning counterclockwise to add lubricating oil into the oil storage box 3 .

[0029] Furthermore, a plug 12 is provided on one side of the plugging ring 4 facing the sleeve body 1 , and the size of the plug 12 matches the upper oil groove 6 , the lower oil groove 7 and the limiting groove 11 .

[0030] It should be noted that the blocking ring 4 prevents the lubricating oil from flowing out through the plug 12 and assists in alignment through the limit groove 11. After the alignment is completed, the blocking ring 4 needs to be welded to the sleeve body 1 to achieve a sealing effect.

[0031] Furthermore, the top end of the twist cap 5 passes through the tube wall of the sleeve body 1 and is threadedly connected to the bottom of the sleeve body 1 .

[0032] It should be noted that the twist cap 5 can be disassembled by rotating it counterclockwise. After disassembly, the oil-absorbing cotton can be inserted into the sleeve body 1, and the environment inside the sleeve body 1 can be judged by the substances absorbed by the oil-absorbing cotton.

[0033] Before the utility model is used, the blocking ring 4 is installed at both ends of the sleeve body 1, and the upper oil groove 6 and the lower oil groove 7 are blocked by the limiting groove 11 and aligned. After the alignment is completed, the blocking ring 4 is installed and welded to the sleeve body 1. When in use, the sleeve body 1 is inserted into the bearing seat of the rotating part, and the bearing seat is connected through the flange ring 2. After the fixing is completed, the box cover 10 is opened by counterclockwise rotation, and lubricating oil is added to the oil storage box 3. The lubricating oil enters the upper oil groove 6 through the oil outlet pipe 9, flows along the upper oil groove 6 to the lower oil groove 7 and the annular groove 8, and the excess lubricating oil is stored in the oil storage box 3. When the equipment is started, the lubricating oil is rotated in the sleeve body 1 by the rotation of the rotating shaft. An oil film is formed inside the sleeve 1 to achieve lubrication. When the lubricating oil is consumed, the lubricating oil in the oil storage box 3 enters the sleeve 1 under the action of gravity. The worker can judge whether the lubricating oil needs to be replenished by observing the remaining lubricating oil in the oil storage box 3. During operation, the twist cap 5 can be disassembled by turning counterclockwise at any time. After disassembly, the oil-absorbing cotton is inserted into the sleeve 1. The oil-absorbing cotton will absorb the oil and dust on the outer wall of the shaft and the lower oil groove 7. The oil-absorbing cotton is taken out and observed to judge whether the dust inside the sleeve 1 will affect the operation of the equipment, thereby achieving the role of timely discovering problems and maintaining them, thereby avoiding potential risks and reducing the failure rate of rotating equipment.

[0034] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
