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

[0019] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are all based on the attached Figure 1 drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0020] As Figure 1-2As shown in the figure, a self-lubricating bearing for a textile machine includes a rotating shaft 3, a bearing having an outer ring 1 and an inner ring 2, a delivery pipe 4, and a spiral blade 5. One end of the delivery pipe 4 is fixedly connected to the outer ring 1, and a through hole 6 is provided at this end. At the same time, the through hole 6 communicates with the raceway of the outer ring 1. A spiral blade 5 is arranged inside the delivery pipe 4. One end of the spiral blade 5 is coaxially and fixedly connected to a transmission shaft 15. The transmission shaft 15 is connected to the rotating shaft 3 arranged inside the inner ring 2 through a transmission assembly. A lubricating oil filter 9 is detachably connected to the outer wall of the delivery pipe 4. One end of the lubricating oil filter 9 is detachably connected to a hose 11. The end of the hose 11 facing away from the delivery pipe 4 communicates with the raceway of the outer ring 1.

[0021] Specifically, one end of the delivery pipe 4 is fixedly connected to the outer ring 1 and can communicate with the raceway inside the outer ring 1 through the through hole 6. The inner ring 2 supports the rotation of the rotating shaft 3. After the rotating shaft 3 rotates, it drives the transmission shaft 15 and the spiral blade 5 to rotate through the transmission assembly, so that the spiral blade 5 extracts the lubricating oil in the raceway and sends it to the lubricating oil filter 9 for filtration, and then transports it back to the raceway after filtration.

[0022] Furthermore, the transmission assembly includes a gear ring 13 and a gear 14. The gear 14 is fixedly connected to the transmission shaft 15. The gear ring 13 is fixedly sleeved on the rotating shaft 3, and the gear ring 13 meshes with the gear 14.

[0023] Specifically, the rotating shaft 3 is driven to rotate by a power output source, such as an electric motor, etc. Furthermore, the rotating shaft 3 can drive the gear ring 13 to rotate, thereby driving the gear 14 to rotate through meshing.

[0024] Furthermore, a connecting pipe 7 is arranged on the outer wall of the delivery pipe 4 near the end of the oil delivery. A screw sleeve 8 is screwed on the connecting pipe 7, and the screw sleeve 8 communicates with the oil inlet end of the lubricating oil filter 9.

[0025] Specifically, by rotating the lubricating oil filter 9, the screw sleeve 8 can be driven to rotate, so that the screw sleeve 8 can be installed on the connecting pipe 7 or disassembled from the connecting pipe 7, so as to facilitate the replacement of the lubricating oil filter 9.

[0026] Furthermore, the oil outlet end of the lubricating oil filter 9 is fixedly communicated with a liquid outlet pipe 10. The liquid outlet pipe 10 is detachably connected to the hose 11. The end of the hose 11 facing away from the liquid outlet pipe 10 is detachably connected to a liquid inlet head 12. The end of the liquid inlet head 12 facing away from the hose 11 communicates with the raceway of the outer ring 1.

[0027] Specifically, when the lubricating oil filter 9 needs to be replaced, by disassembling the hose 11, it is then convenient to disassemble or install the lubricating oil filter 9.

[0028] Furthermore, both ends of the hose 11 are respectively fastened to the liquid outlet pipe 10 and the liquid inlet head 12 through pipe clamps so that the hose 11 can be disassembled. The outer ring 1 has an opening that can communicate with the liquid inlet head 12 and the through hole 6.

[0029] Furthermore, the inner side of the outer ring 1 is fitted and slidably engaged with the outer side of the inner ring 2. The outer ring 1 and the inner ring 2 can maintain the sealing of the raceway while not affecting the rotation of the inner ring 2. The lubricating oil flows in the raceway to maintain lubrication.

[0030] In the above structure, when the rotating shaft 3 rotates, the gear ring 13 on the rotating shaft 3 rotates synchronously to drive the gear 14 to rotate by meshing. The gear 14 further drives the spiral blade 5 to rotate. Then, the lubricating oil enters the conveying pipe 4 through the through hole 6, and is then conveyed to the lubricating oil filter 9 through the connecting pipe 7 and the screw sleeve 8 for filtration. After filtration, the lubricating oil enters the liquid outlet pipe 10, and then re-enters the bearing raceway through the hose 11 and the liquid inlet head 12 to lubricate the bearing, so that the lubricating oil can be filtered to ensure the efficacy of the lubricating oil.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
