Description
Technical field
The utility model relates to a kind of geared parts more particularly to a kind of planetary gears.
Background technique
In the transmission system of speed reducer, there is a kind of transmission gear, outside is provided with a large gear, is internally provided with
Multiple gears are around the rotation of center size, the rotation of the track of operation similar to solar system inner planet, therefore this kind of power train
Collectively referred to as planetary gear train, central gear are sun gear, and the gear around sun gear rotation is referred to as planetary gear.This planet
It is inconvenient that gear lubricates during rotating, and gear wear is very fast during long-time use, and service life is short.
Summary of the invention
The purpose of this utility model is: providing a kind of planetary gear.
In order to achieve the above purposes, the technical solution adopted by the utility model is:
A kind of planetary gear, including gear body, are provided with teeth in the gear body outer rim, between the adjacent teeth
Gear body be equipped with oil outlet, bearing groove is equipped in the middle part of the gear body, the inner wall of the bearing groove is equipped with bearing gear
Wheel, the gear body between the adjacent Bearing gear pair are equipped with oil outlet A, and the gear body is equipped with oil duct, described
Oil duct is connected to oil outlet A and oil outlet, passes through oil-piping connection between the oil duct and oil outlet, the oil-piping of crossing is single
Xiang Guan.
The oil duct is equipped with fuel feed hole, is equipped with strainer in the fuel feed hole.
The gear body is equipped with lightening hole.
In the above-mentioned technical solutions, compared with prior art, the beneficial effect reached is: gear body is equipped with oil duct,
And the inwardly and outside connection oil outlet A and oil outlet of oil duct, improve planetary gear in the process of running with other bearings and
Lubricity between gear extends its service life；And the oil-piping of crossing between oil duct and oil outlet is uniguide, is avoided
The reflux of used machine oil.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model embodiment one.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Embodiment one:
As described in Figure 1, a kind of planetary gear of the utility model, including gear body 1 are set in 1 outer rim of gear body
Teeth 2 are equipped with, the gear body 1 between the adjacent teeth 2 is equipped with oil outlet 3, is equipped with bearing in the middle part of the gear body 1
Slot 4, the inner wall of the bearing groove 4 are equipped with Bearing gear 5, and the gear body 1 between the adjacent Bearing gear 5 pair is equipped with
Oilhole A6, the gear body 1 are equipped with oil duct 7, and the oil duct 7 is connected to oil outlet A6 and oil outlet 3, the oil duct 7 with go out
Passed through the connection of oil-piping 8 between oilhole 3, the oil-piping 8 of crossing is uniguide.
The oil duct 7 is equipped with fuel feed hole 9, is equipped with strainer 10 in the fuel feed hole 9.
The gear body 1 is equipped with lightening hole 11.
In the above-mentioned technical solutions, compared with prior art, the beneficial effect reached is: gear body 1 is equipped with oil duct
7, and the inwardly and outside connection oil outlet A6 and oil outlet 3 of oil duct 7, improve planetary gear in the process of running with other bearings
And the lubricity between gear, extend its service life；And the oil-piping 8 of crossing between oil duct 7 and oil outlet 3 is unidirectional
Pipe, avoids the reflux of used machine oil.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
