Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and in particular relates to a bearing which is convenient for oil injection. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings are constantly running during work. As bearings run, they are prone to wear. Therefore, they need to be continuously injected with engine oil to improve lubrication. Once bearings are severely worn, they will affect the mechanical transmission efficiency, resulting in reduced transmission efficiency. In severe cases, the transmission shaft will be damaged.

[0028] In a specific embodiment of the present utility model, the fixing bolts 7 and the fixing nuts 8 facilitate the fixing and disassembly of the lower base 1 and the mounting seat 2, thereby facilitating the inspection and repair of the bearing body 4.

[0029] Specifically, the oil filling mechanism 6 includes an oil inlet box 601 installed on the top of the mounting seat 2, the surface of the oil inlet box 601 is threadedly connected with an adjusting threaded column 602, the surface of the adjusting threaded column 602 is threadedly connected with an internal threaded ring 603, the surface of the adjusting threaded column 602 is slidably connected with a blocking block 605, the outer side of the adjusting threaded column 602 is sleeved with a reset spring 604, and the two ends of the reset spring 604 are respectively in contact with the internal threaded ring 603 and the blocking block 605, the surface of the oil inlet box 601 is rotatably connected with a special-shaped protrusion 606 adapted to the blocking block 605, and the surface of the special-shaped protrusion 606 is installed with a connecting rod 607.

[0030] In a specific embodiment of the utility model, the angle of the special-shaped protrusion 606 is adjusted by rotating the connecting rod 607. At this time, the special-shaped protrusion 606 exerts a force on the blocking block 605. At this time, the blocking block 605 moves upward and exerts a force on the return spring 604. At this time, the lubricating oil leaked through the connecting groove 504 will flow into the interior of the mounting seat 2 through the oil inlet tank 601. After loosening the connecting rod 607, the blocking block 605 will be reset under the reaction force of the return spring 604.

[0031] Specifically, a leak-proof protrusion 608 is provided on the surface of the oil inlet tank 601, a sealing groove 609 adapted to the leak-proof protrusion 608 is provided at the bottom of the blocking block 605, a first inclined block 610 is provided on the surface of the oil inlet tank 601 and on one side of the leak-proof protrusion 608, and a second inclined block 611 adapted to the first inclined block 610 is provided at the bottom of the blocking block 605.

[0032] In a specific embodiment of the utility model, by providing the anti-leakage protrusion 608 and the sealing groove 609, the lubricating oil can be blocked, thereby reducing the probability of lubricating oil leakage. At the same time, by using the first inclined block 610 and the second inclined block 611 in coordination, the movement trajectory of the lubricating oil can be guided, and the connecting groove 504 can be sealed when not in use.

[0033] Specifically, the oil delivery mechanism 5 includes an oil delivery box 501 installed on one side of the oil filling mechanism 6, the surface of the oil delivery box 501 is threadedly connected with a threaded knob 502, the inner wall of the oil delivery box 501 is slidably connected with an oil push plate 503, and the threaded knob 502 is fixedly connected to the surface of the oil push plate 503, a sealing member 505 is installed on the upper surface of the oil delivery box 501, and a connecting groove 504 is opened on the surface of the oil delivery box 501 close to the oil inlet tank 601, and the connecting groove 504 is connected to the oil inlet tank 601.

[0034] In a specific embodiment of the utility model, lubricating oil can be injected into the interior of the oil tank 501 through the sealing member 505, and then the oil push plate 503 is driven to move by rotating the threaded knob 502. The movement of the oil push plate 503 drives the lubricating oil to move. When the blocking block 605 is opened, the lubricating oil will flow out through the connecting groove 504, and then the threaded knob 502 can be continued to be rotated to move the lubricating oil. At the same time, the amount of lubricating oil in the oil tank 501 can be observed through the moving length of the threaded knob 502.

At this time, the bearing body 4 can be used. The lubricating oil can be injected into the oil tank 501 through the sealing member 505. Then, the oil pushing plate 503 is driven to move by rotating the threaded knob 502. The movement of the oil pushing plate 503 drives the lubricating oil to move. When the blocking block 605 is opened, the lubricating oil will flow out through the connecting groove 504. Then, the threaded knob 502 can be continuously rotated to move the lubricating oil. At the same time, the amount of lubricating oil in the oil tank 501 can be observed by the moving length of the threaded knob 502. , by rotating the connecting rod 607, the special-shaped protrusion 606 is driven to adjust the angle. At this time, the special-shaped protrusion 606 applies a force to the blocking block 605. At this time, the blocking block 605 moves upward and applies a force to the return spring 604. At this time, the lubricating oil leaked through the connecting groove 504 will flow into the interior of the mounting seat 2 through the oil inlet tank 601. After loosening the connecting rod 607, the blocking block 605 will be reset under the reaction force of the return spring 604, and the lubricating oil inside the oil delivery mechanism 5 will be delivered to the interior of the mounting seat 2, thereby refueling the bearing body 4, and then the lubricating oil can be pushed to the interior of the oil filling mechanism 6 through the oil delivery mechanism 5.
