DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] A self-lubricating internal gear provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0024] Combination Figure 1-3As shown, the utility model provides a self-lubricating internal gear, comprising: a gear mechanism 100 and a lubrication assembly 200, wherein teeth are arranged in the gear mechanism 100, and the opening positions of the oil return channel 250 are located on both sides of the teeth.

[0025] The lubrication assembly 200 is disposed on the gear mechanism 100, and the lubrication assembly 200 includes an oil storage tank 210 provided in the gear mechanism 100, an oil through hole 220 provided in the oil storage tank 210 and connected to the oil storage tank 210, an oil valve 230 embedded in the gear mechanism 100 and connected to the oil storage tank 210, an oil return baffle ring 240 fixed on both sides of the gear mechanism 100, an oil return flow channel 250 provided in the oil return baffle ring 240, and an oil return flow channel 250 provided in the gear mechanism 100 and connected to the oil storage tank 210 and the oil return flow channel 250. The oil inlet hole 260 and the oil discharge hole 270 opened on the inner side of the gear mechanism 100 and connected to the oil storage tank 210 can inject the lubricating oil into the oil storage tank 210 through the lubrication component 200, and then flow through the oil through hole 220. The trapezoidal inner cavity and the opening are used for conduction, which can ensure the structural strength of the gear mechanism 100 while storing oil. After use, the lubricating oil will flow to both sides of the gear mechanism 100. At this time, the filter cotton 251 is used to filter the lubricating oil so that it can flow back into the oil storage tank 210 for recycling. This solves the problem of regular replenishment of the small amount of oil storage.

[0026] Specifically, the oil storage tank 210 is arranged around the gear mechanism 100, and filter cotton 211 is staggered in the oil storage tank 210. The oil drain hole 270 is a trumpet-shaped structure, and the oil drain hole 270 is arranged on the inner side of the filter cotton 211. The staggered filter cotton 211 can filter the lubricating oil to be discharged through the oil drain hole 270 to prevent debris from damaging the gears, and the trumpet-shaped structure facilitates the stable output of the lubricating oil.

[0027] Furthermore, the oil storage tank 210 has a trapezoidal inner cavity structure, which has little effect on the structural strength of the gear mechanism 100 and can store relatively more oil.

[0028] On the other hand, the oil return channel 250 is filled with filter cotton 251, and one end of the filter cotton 251 located on the inner side of the gear mechanism 100 is a trumpet-shaped structure, which can filter the recovered lubricating oil.

[0029] Furthermore, the inner diameter of the oil inlet hole 260 gradually decreases from the oil return channel 250 side to the oil storage tank 210 side, which can prevent the lubricating oil in the oil storage tank 210 from flowing back into the oil return channel 250 .

[0030] It should be noted that the outer side of the oil return baffle ring 240 is also provided with an oil residue groove 241 connected to the oil return channel 250, so that the residue filtered by the filter cotton 251 can flow into the oil residue groove 241 for collection, thereby preventing the lubricating oil from contaminating the integral gear.

[0031] Furthermore, a wear-resistant gasket 242 is fixed to the inner side of the oil return baffle ring 240 , which can improve the wear resistance of the inner side of the oil return baffle ring 240 and increase its service life.

[0032] The working principle and use process of the utility model are as follows: first, the lubricating oil is injected into the oil storage tank 210, and then circulated through the oil through hole 220. When in use, the lubricating oil flows out from the oil discharge hole 270, and then flows along the two sides of the teeth in the gear mechanism 100 to the oil return channel 250, and then flows back to the oil storage tank 210 through the oil inlet hole 260 after being filtered by the filter cotton 251, so as to achieve recycling.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
