Then, the movement of two clamping plates is controlled by a moving rod, realizing the effect of controlling the oil outlet, solving the problem that the existing gears generally add lubricants externally, improving the service life of the gears, and thus solving the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A gear with a self-lubricating function, including a gear disc. The outer side surface of the gear disc is formed with protruding teeth in an array. A plurality of oil storage cavities are arranged at equal intervals along the circumferential direction inside the gear disc. An oil outlet is arranged on the inner wall of the oil storage cavity close to the tooth. An oil outlet groove communicating with the oil outlet is arranged on the inner side surface of the tooth. A first oil-absorbing cotton strip is arranged inside the oil storage cavity. One end of the first oil-absorbing cotton strip is arranged inside the oil outlet and fixedly connected to two second oil-absorbing cotton strips. The second oil-absorbing cotton strips are arranged inside the oil outlet groove. Symmetric clamping plates are arranged on both inner walls of the oil outlet. Two symmetric first springs are arranged at the end of the clamping plate far from the oil outlet. A U-shaped moving plate is arranged on the side surface of the clamping plate close to the oil outlet. Symmetric partition blocks are arranged on both sides of the first oil-absorbing cotton strip. One end of the partition block is provided with a moving rod. The end of the moving rod far from the partition block passes through the gear disc and is located between two teeth. A second spring is sleeved on the outer side surface of the moving rod inside the gear disc.

[0007] Furthermore, two symmetric rectangular grooves are formed on the inner side of the oil storage cavity close to the teeth. The clamping plate is slidably connected to the inner wall of the rectangular groove. Sliding grooves are formed on both inner walls of the rectangular groove. Sliders are fixedly connected to both sides of the clamping plate, and the sliders are slidably connected to the inside of the sliding grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] A gear with self-lubricating function provided by the utility model, when in use, when two gears are meshed, the teeth on one side of the gear disk squeeze the moving rod on the other gear, driving the moving rod to move towards the center of the gear disk and squeezing the second spring through the circular ring. The movement of the moving rod drives the partition block to move, and the movement of the partition block drives the two U-shaped moving plates to move away from each other. The two U-shaped moving plates drive the two clamping plates to move away from each other and squeeze the first spring. The two clamping plates leave the oil outlet and loosen the first oil-absorbing cotton strip. The first oil-absorbing cotton strip will absorb the lubricating oil inside the oil storage cavity and transmit it to the second oil-absorbing cotton strip. The meshed teeth of the two gear disks will squeeze the second oil-absorbing cotton strip to squeeze out the lubricating oil inside it, and evenly apply the overflowing lubricating oil to the teeth of the gear set, achieving the effect of automatic lubrication. When the moving rod is not squeezed, the second spring will drive the moving rod away from the center of the gear disk and return to its original position. The first spring will also use its own elastic force to push the clamping plate into the oil outlet through the rectangular opening. The two clamping plates move in the same direction to clamp the first oil-absorbing cotton strip, preventing the first oil-absorbing cotton strip from continuing to absorb lubricating oil and transmitting it to the second oil-absorbing cotton strip, achieving the effect of controlling the oil output, solving the problem that existing gears generally add lubricants externally, and improving the service life of the gears.

[0024] In order to solve the technical problem that the existing gears are mainly lubricated by the method of manually regularly injecting lubricating oil into the meshing parts of the gears, which needs to be realized by means of tool injection, the whole process is too cumbersome, and it cannot ensure timely lubrication of the gears, affecting the service life of the gears, as Figures 1-7 shown, the following preferred technical solutions are provided:

[0025] A gear with self-lubricating function includes a gear disc 1. The outer side surface of the gear disc 1 is formed with protruding teeth 2 in an array. A plurality of oil storage cavities 3 are arranged at equal intervals along the circumferential direction inside the gear disc 1. An oil outlet 4 is opened on the inner wall of the oil storage cavity 3 close to the teeth 2. An oil groove 5 communicating with the oil outlet 4 is opened on the inner side surface of the teeth 2. A first oil-absorbing cotton strip 6 is arranged inside the oil storage cavity 3. One end of the first oil-absorbing cotton strip 6 is arranged inside the oil outlet 4 and fixedly connected to two second oil-absorbing cotton strips 7. The second oil-absorbing cotton strips 7 are arranged inside the oil groove 5. Symmetrically arranged clamping plates 11 are arranged on the inner side walls on both sides of the oil outlet 4.

The end of the moving rod 17 away from the partition block 16 passes through the gear disc 1 and is located between two teeth 2. A second spring 20 is sleeved on the outer side surface of the moving rod 17 inside the gear disc 1.

[0026] Specifically, during use, when two gears are engaged, the teeth 2 on one side of the gear disk 1 squeeze the moving rod 17 on the other side of the gear disk 1, driving the moving rod 17 to move towards the center of the gear disk 1 and squeezing the second spring 20.

The meshing teeth 2 of the two gear disks 1 will squeeze the second oil-absorbing cotton strip 7 to squeeze out the lubricating oil inside it, and evenly apply the overflowing lubricating oil to the teeth 2 of the gear set, achieving the effect of automatic lubrication. When the moving rod 17 is not squeezed, the second spring 20 will drive the moving rod 17 to move away from the center of the gear disk 1 and return to its original position. The first spring 13 will also use its own elastic force to push the clamping plate 11 into the oil outlet 4 through the rectangular opening 9. The two clamping plates 11 move in the same direction to clamp the first oil-absorbing cotton strip 6, preventing the first oil-absorbing cotton strip 6 from continuing to absorb lubricating oil and transferring it to the second oil-absorbing cotton strip 7, achieving the effect of controlling the oil output, solving the problem that existing gears generally add lubricant externally, and improving the service life of the gears.
