[0002] Bearings are key components in mechanical engineering, used to support and reduce the friction of rotating equipment so that the equipment can run smoothly. Friction is one of the main causes of energy loss in mechanical systems. Lubricants can form a lubricating film to reduce friction, making bearings rotate more smoothly, helping to save energy, reduce power loss, and improve system efficiency. Therefore, a bearing grease oiler is needed.

[0003] After searching the Chinese patent document with the announcement number CN214744867U, it is disclosed that an anti-oil overflow bearing oiler includes a shell, an oil bottle and a pressurizing component. The oiler is provided with an oil-absorbing sponge, which can absorb the lubricating oil overflowing during oil filling to prevent dripping and waste. When the button is pressed, the piston pulls the sliding rod through the connecting rod, the sliding rod drives the rope column, the rope column pulls the pull rope to move, so that the two connecting plates are close to each other, the second spring is compressed, and the oil-absorbing sponge is fluffy after leaving the inner end of the oil collecting cylinder, so as to absorb the lubricating oil overflowing during oil filling. After releasing the button, the first spring is deformed and restored to push the piston to reset. During the piston resetting process, the connecting rod is pushed to reset and release the pull rope. The second spring is deformed and restored to open the connecting plate, so that the oil-absorbing sponge is squeezed close to the inner end of the oil collecting cylinder, and most of the lubricating oil in the sponge flows into the oil collecting cylinder through the small hole, so as to facilitate the collection of the absorbed lubricating oil.

The top of the refueling pipe 4 is fixedly connected to a limiting block 12 to prevent the bearing from being placed in the refueling pipe 4 and filling too much oil to the middle of the bearing. The oil is accurately filled and lubricated at the position where the bearing needs it. After lubrication is completed, the hydraulic rod 6 shrinks back. At this time, the spring 15 that releases the pressure will rebound again, pushing the refueling pipe 4 and the piston 14 upward together, waiting for the next bearing lubrication cycle. The oil tank 8 is fixedly connected to the top of the base 1, and the one-way valve 11 is fixedly connected to the left side of the oil tank 8.
