Description

Technical Field

[0001] The utility model relates to the technical field of oil-containing bearings, in particular to an oil-containing bearing which is convenient for adding lubricating oil. Background Art

[0002] Oil-containing bearings have now become an indispensable basic part for the development of various industrial products such as automobiles, home appliances, audio equipment, office equipment, agricultural machinery, precision machinery, etc. They are sintered bodies made of metal powders and other materials through powder metallurgy. They are porous in themselves. The number, size and shape of the pores can also be controlled and adjusted during the manufacturing process, with high flexibility and freedom. Due to the porous structure, they can absorb lubricating oil very well. After the oil-containing bearing is impregnated with 10% to 40% of lubricating oil, it can lubricate itself during the operation of the equipment. Therefore, oil-containing bearings have a very obvious effect on mechanical equipment that has a long running time and is difficult to maintain lubrication. After the oil-containing bearing is impregnated with lubricating oil and put into operation, the temperature of the oil-containing bearing will rise accordingly with the friction and heat of the mechanical equipment. Since the expansion coefficient of oil is higher than that of metal, the lubricating oil in the oil-containing bearing will automatically enter the lubrication surface to lubricate the bearing. When the mechanical equipment stops running, the temperature of the oil-containing bearing drops and the lubricating oil will be sucked back into the pores.

[0003] At present, when adding lubricating oil to oil-containing bearings, the staff cannot control the amount of lubricating oil added according to the needs each time, which leads to the problem of too much or too little lubricating oil being easily added. When too much lubricating oil is added, the lubricant pressure inside the bearing will increase, which may cause seal failure or lubricant leakage. The leaked lubricating oil may pollute the surrounding environment and may even affect the normal operation of other equipment or components. Too much lubricating oil will also increase the friction inside the bearing, causing the lubricant to fail prematurely and reduce the lubrication performance. Adding too little lubricating oil will cause the bearing to lack sufficient lubricant, resulting in increased bearing friction and aggravated wear, which will seriously affect the service life and performance of the bearing. The lack of cooling effect of the lubricant may cause the bearing to overheat, thus causing failure or damage. Utility Model Content

[0023] The surface of the inner wall of the rotating sleeve 5 is provided with an internal thread, and the external thread 6 is provided on the front and rear surfaces of the oil-containing bearing body 1, and the inner wall of the rotating sleeve 5 is threadedly connected to the surface of the oil-containing bearing body 1. The length of the inner wall of the rotating sleeve 5 is the same as the length of the oil-containing bearing body 1. When the staff rotates the rotating sleeve 5, the rotating sleeve 5 will move on the surface of the oil-containing bearing body 1. When the rotating sleeve 5 moves on the surface of the oil-containing bearing body 1, the staff can observe the left side of the rotating sleeve 5 moving to the position of the scale line 7, so as to accurately control the amount of lubricating oil added.

[0024] A limiting groove 13 is provided on the surface of the right side of the inner wall of the rotating sleeve 5, and the right end of the connecting rod 9 extends to the inside of the limiting groove 13 and fixes the limiting block 12. The limiting block 12 is located inside the limiting groove 13 and is slidably connected to the inner wall of the limiting groove 13. When the rotating sleeve 5 moves to the right on the surface of the oil-containing bearing body 1, the limiting block 12 is located inside the limiting groove 13, so that the rotating sleeve 5 pulls the connecting rod 9 to move to the right, and then the movable ring 8 moves inside the oil storage chamber 2, so that the oil extraction pipe 3 extracts the lubricating oil.

[0025] A sealing strip 11 is bonded to the edge of the left side surface of the moving ring 8, and the material of the sealing strip 11 is nitrile rubber. When the moving ring 8 moves, the setting of the sealing strip 11 can improve the sealing effect of the moving ring 8 and prevent the lubricating oil from passing through the moving ring 8 and flowing to the other side of the oil storage chamber 2.

[0026] The cross-sectional area of ​​the oil extraction pipe 3 decreases from the right end to the left end, and the inner wall of the sealing cover 4 is clamped with the oil extraction pipe 3. When the staff puts the rubber tube on the surface of the oil extraction pipe 3 to extract the lubricating oil, the outer shape design of the oil extraction pipe 3 makes it convenient to put the rubber tube on the surface of the oil extraction pipe 3.

[0027] The surface of the rotating sleeve 5 is provided with grooves 14, the number of the grooves 14 is several, and the grooves 14 are distributed in a ring shape with the center of the rotating sleeve 5 as the center. Through the arrangement of the grooves 14 on the surface of the rotating sleeve 5, when the staff rotates the rotating sleeve 5 by hand to absorb oil, it is convenient for the staff to rotate the rotating sleeve 5.

[0028] Working principle: When the staff needs to refuel the oil-containing bearing, the staff first removes the sealing cover 4 on the surface of the oil extraction pipe 3, and then takes out the rubber tube, which is set on the surface of the oil extraction pipe 3. The staff puts the other end of the rubber tube into the lubricating oil barrel, and then the staff can rotate the rotating sleeve 5, so that the rotating sleeve 5 moves to the right on the surface of the oil-containing bearing body 1, and the rotating sleeve 5 pulls the connecting rod 9 to move to the right, and the connecting rod 9 pulls the moving ring 8 to move to the right, and the oil extraction pipe 3 will suck the lubricating oil into the oil storage chamber 2 After the staff rotates the left side of the rotating sleeve 5 to the corresponding scale line 7 position according to work needs, the inside of the oil storage chamber 2 is added with lubricating oil of the corresponding scale line 7 capacity. After the lubricating oil is added, the staff can again set the sealing cover 4 on the surface of the oil extraction pipe 3 to seal the oil storage chamber 2. When the lubricating oil in the oil storage chamber 2 needs to be refilled after use, the staff needs to first rotate the rotating sleeve 5, move the movable ring 8 to the leftmost side of the oil storage chamber 2, and then connect the oil extraction pipe 3 to the rubber tube for subsequent lubricating oil refueling operations.
