Problems solved by technology

For the current gears, when adding lubricating oil, the liquid lubricating oil can only be poured on the surface of the gear teeth by pouring. In this process, most of the lubricating oil cannot be applied to the surface of the gear teeth, but is lost from the side. It causes a lot of waste, and it is difficult to lubricate the lower gear teeth; and, during the operation of the gear pair, considering the safety issue, it is impossible to add lubricating oil to the gears

Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0011] exist figure 1 In the shown embodiment, the oil storage lubrication gear includes a gear body 1, gear teeth 11, a shaft hole 2 matching with the shaft body in the center of the gear body 1, a keyway 14 is opened on the shaft hole 2, and the shaft An annular inner groove 15 is also provided on the annular surface of the hole 2, and the annular inner groove 15 leads to the surface of the gear body 1 through a liquid injection hole 13, and the annular inner groove 15 is connected with each of the gear teeth 11. Lubricating passages 12 are opened between the tooth roots, and permeate (not shown) is arranged in the lubricating passages 12 .

[0012] For the above-mentioned oil storage lubrication gear, the diameter of the annular inner groove 15 is 1 / 5-1 / 6 of the diameter of the dedendum circle.

[0013] In the aforementioned oil storage lubricating gear, the ...

Abstract

The invention provides an oil-accumulating lubrication gear, belonging to a mechanical part. The oil-accumulating lubrication gear comprises a gear body and a plurality of gear teeth, the center of the gear body is provided with a shaft hole matched with a shaft body, the shaft hole is provided with a key slot, the annular surface of the shaft hole is also provided with an annular inner groove, the annular inner groove is communicated with the surface of the gear body through a fluid injection hole, a plurality of lubrication channels are arranged between the annular inner groove and the root of each gear tooth, and permeable substances are arranged in the lubrication channels. The transmission of a gear pair can be realized effectively, and lubricating oil can be stored in the gear and can be automatically released to the surfaces of the gear teeth during the gear transmission process. Therefore, the lubricating oil can be saved, and the manual lubrication can be eliminated.

Description

Technical field [0001] The invention relates to a mechanical part, especially a mechanical gear, including a wheel body and gear teeth. Background technique [0002] As a common mechanical part, the gear is mainly used for mechanical transmission. It includes the gear body and the teeth. The driving gear and the driven gear carry out rolling transmission through the mutual meshing of the teeth. During the process, if there is no lubrication on the tooth surface, the rolling friction between the teeth will be large, and the gears will be easily damaged by heat. Therefore, it is necessary to add lubricating oil to the gear pair regularly. For the current gears, when adding lubricating oil, the liquid lubricating oil can only be poured on the surface of the gear teeth by pouring. In this process, most of the lubricating oil cannot be applied to the surface of the gear teeth, but is lost from the side. It causes a lot of waste, and it is difficult to lubricate the lower gear te...
