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
Affiliated technical field
The present invention relates to a kind of mechanical parts, especially, is a kind of mechanical gear, comprises the wheel body and the gear teeth.
Background technique
Gear is mainly used in mechanical transmission as a kind of common mechanical parts, and it includes the gear body and the gear teeth; Carry out the rolling type transmission through being meshing with each other of the gear teeth between driving gear and the driven gear; In the intermeshing process, if the wheel flank of tooth is unlubricated, then the rolling frictional resistance between the gear teeth is bigger between the gear teeth; Therefore the gear damage of generating heat easily needs periodically gear pair to be added lubricant oil.And, when adding lubricant oil, can only adopt the mode of cast that lubricating oil is watered at tooth surface for present gear; In this process, most of lubricant oil can not be coated with and moisten to tooth surface, and runs off from the side; Caused very big waste, and the gear teeth below being in are difficult to again obtain lubricated; And, in the gear pair running, consider safety issue, can't add lubricant oil to gear.
Summary of the invention
In order to address the above problem; The object of the present invention is to provide a kind of oil lubrication gear that holds; This holds the oil lubrication gear not only can effectively realize the gear pair transmission, and can store lubricant oil in gear inside, and in the gear transmission process, is released into tooth surface voluntarily; Both practice thrift lubricant oil, omitted manual application of lubricant operation again.
The technical solution adopted for the present invention to solve the technical problems is: this holds the oil lubrication gear and comprises that gear body, the gear teeth, said gear body center have the axis hole that matches with axis body; Have keyway on this axis hole; Also offer annular inner groovy on the annular surface of said axis hole one; This annular inner groovy leads to said gear body surface through a liquid filling hole, and should the annular inner groovy and the tooth root of each said gear teeth between all have lubrication channel, be provided with penetrant in the said lubrication channel.
As preferably, the diameter of said annular inner groovy is the 1/5-1/6 of root diameter.
As preferably, the outer end of said lubrication channel is in the tooth root central authorities of the said gear teeth.
As preferably, said penetrant is a sponge.
Beneficial effect of the present invention is: this holds the oil lubrication gear in use; Only needing that lubricant oil is injected said annular inner groovy through said liquid filling hole seals in the cavity that forms with axis body; Then in the gear rotary course, lubricant oil slowly is coated with through the penetrant in the said lubrication channel under the effect of centrifugal force or gravity and moistens to said tooth surface, thereby realizes the self oiling to gear pair; This kind lubricating system had both been practiced thrift lubricant oil, had omitted manual application of lubricant operation again.
Description of drawings
Fig. 1 is the schematic perspective view that originally holds an embodiment of oil lubrication gear.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In the embodiment shown in fig. 1; This holds the oil lubrication gear and comprises that gear body 1, the gear teeth 11, said gear body 1 central authorities have the axis hole 2 that matches with axis body; Have keyway 14 on this axis hole 2; Also offer annular inner groovy 15 on the annular surface of said axis hole 2 one; This annular inner groovy 15 leads to said gear body 1 surface through a liquid filling hole 13, and should annular inner groovy 15 and the tooth root of each said gear teeth 11 between all have lubrication channel 12, be provided with penetrant (not shown) in the said lubrication channel 12.
The above-mentioned oil lubrication gear that holds, the diameter of said annular inner groovy 15 is the 1/5-1/6 of root diameter.
The above-mentioned oil lubrication gear that holds, the outer end of said lubrication channel 12 are in the tooth root central authorities of the said gear teeth 11.
The above-mentioned oil lubrication gear that holds, said penetrant is a sponge.
The above-mentioned oil lubrication gear that holds is adding man-hour; Can obtain gear body 1 and axis hole 2, annular inner groovy 15 through casting earlier; After the metal working finishing, adopt the gear cutting knife to cut out the said gear teeth 11 again, cut out said keyway 14 afterwards again; Adopt drill bit to get out said liquid filling hole 13 and lubrication channel 12 again, at last said penetrant is inserted said lubrication channel 12.
Above-mentioned holds the oil lubrication gear in use; Only needing that lubricant oil is injected said annular inner groovy 15 through said liquid filling hole 13 seals in the cavity that forms with axis body; Then in the gear rotary course, lubricant oil slowly is coated with through the penetrant in the said lubrication channel 12 under the effect of centrifugal force or gravity and moistens to the said gear teeth 11 surfaces, thereby realizes the self oiling to gear pair; This kind lubricating system had both been practiced thrift lubricant oil, had omitted manual application of lubricant operation again.
Claims (4)
