Description

Technical Field

[0001] The utility model relates to a transmission device, in particular to a transmission gear. Background Art

[0002] The conventional method of lubricating the transmission shaft in a gearbox is to inject lubricating oil into the gearbox to a height of about half of the gearbox, and immerse the gears in the lubricating oil through the rotation of the gears. However, this lubrication method is not efficient. When the gearbox is not working for a long time, some gears will not be lubricated for a long time.

[0003] In summary, how to achieve lubrication of gears has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to achieve lubrication of gears;

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model is a transmission gear, comprising: a rotating disk; a gear shaft, which is fixedly arranged at the bottom of the rotating disk; an oil inlet pipe, which is arranged at the top of the rotating disk and is coaxially arranged with the gear shaft; a first oil spray hole and a second oil spray hole which are perpendicular to each other are opened in the rotating disk; the oil inlet pipe is connected with the intersection of the first oil spray hole and the second oil spray hole;

[0007] In this solution, the gear shaft at the bottom of the rotating disk meshes with other gears to rotate, thereby driving the rotating disk to rotate. The oil pipe is connected to the oil inlet pipe through a rotating joint, and the lubricating oil is sprayed to the gear through the oil inlet pipe, the first oil spray hole, and the second oil spray hole. Since the rotating disk rotates with the gear shaft, it can achieve spray lubrication of other gears near the transmission gear, thereby realizing lubrication of the gear.

[0008] In order to limit the axial movement of the transmission gear and prevent splashing to other parts during the spraying process, the utility model adopts a limited step on the rotating disk; a splash shield is sleeved on the limited step;

[0009] The splash guard can limit the upward axial movement of the transmission gear and can prevent the lubricating oil from lubricating the components below the splash guard.

[0010] After the spraying is completed, in order to allow the lubricating oil to enter the gear box, the utility model adopts an oil leakage hole opened inwardly on the rotating disk, and an oil leakage gap is formed between the rotating disk and the splash shield;

[0011] The sprayed oil falls onto the splash shield and then falls to the bottom of the gearbox through the oil leakage gap for collection.

[0012] The beneficial effects of the utility model are as follows: the utility model is a transmission gear, the gear shaft at the bottom of the rotating disk meshes with other gears to rotate, thereby driving the rotating disk to rotate, the oil pipe is connected to the oil inlet pipe through a rotating joint, the lubricating oil is sprayed to the gear through the oil inlet pipe, the first oil spray hole, and the second oil spray hole. Since the rotating disk rotates with the gear shaft, spray lubrication of other gears near the transmission gear can be achieved, thereby realizing the lubrication of the gear.

[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In this solution, the gear shaft at the bottom of the rotating disk meshes with other gears to rotate, thereby driving the rotating disk to rotate. The oil pipe is connected to the oil inlet pipe through a rotating joint, and the lubricating oil is sprayed to the gear through the oil inlet pipe, the first oil spray hole, and the second oil spray hole. Since the rotating disk rotates with the gear shaft, it can achieve spray lubrication of other gears near the transmission gear, thereby realizing lubrication of the gear.

[0021] like Figure 1-3As shown, in order to limit the axial movement of the transmission gear and prevent splashing to other parts during the spraying process, the utility model adopts a limit step 4 provided on the rotating disk 1; a splash shield is sleeved on the limit step 4;

[0022] The splash guard can limit the upward axial movement of the transmission gear and can prevent the lubricating oil from lubricating the components below the splash guard.

[0023] like Figure 1-3 As shown, after the spraying is completed, in order to allow the lubricating oil to enter the gear box, the utility model adopts an oil leakage hole opened inwardly on the rotating disk 1, and an oil leakage gap 7 is formed between the rotating disk 1 and the splash shield;

[0024] The sprayed oil falls onto the splash shield and then falls to the bottom of the gearbox through the oil leakage gap for collection.
