The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model provides one kind detracting high efficiency transmission device, packet for planetary noise reduction
Planet carrier 1 is included, the planet carrier 1 is inserted with solar shaft 2 centrally through horizontal axial trough 101, is equipped on the solar shaft 2
Sun gear 3 inside planet carrier 1, the solar shaft 2 are linked together with horizontal axial trough 101 by spline 7, and connection is simpler
Single, solar shaft 2 can be stably driven with the rotation of planet carrier 1.It is movably installed with by several planet jack-posts 4 inside the planet carrier 1
Several planetary gears 5 engaged with sun gear 3, solar shaft 2 are rotated with sun gear 2 and planet carrier 1, the planetary gear 5 on planet carrier 1
Revolution motion is done around solar shaft 2 in rotation, to constitute a planetary gear system.
As depicted in figs. 1 and 2, trapped fuel slot 102 and shunting oil duct are respectively equipped in the planet carrier 1 and planet jack-post 4
401, the trapped fuel slot 102 is connected by dissipating oilhole road 104 with shunting oil duct 401, and the shunting oil duct 401 is connected with several
The weeping pipe 402 for being pierced by 4 outside of planet jack-post and being inserted into annulus oil groove 501.The planetary gear 5 is internally provided with annulus oil groove
501,501 normal cross-section shape of the annulus oil groove be " V " shape, side section shape be circular ring shape, to make lubricating oil preferably into
Enter annulus oil groove 501, and is rotated relative to planet jack-post 4 in planetary gear 5 or when left and right displacement, oil dripping tube 402 will not
It is touched or is rubbed by planetary gear 5 and arrive, to make the fuel-displaced of planetary gear 5 more stablize.
As shown in Figure 1,501 side of annulus oil groove is connected with several oil outlets 502 for being pierced by 5 outside of planetary gear, institute
It states 102 side of trapped fuel slot and is connected with the oil inlet hole slot 103 for being pierced by 1 surface of planet carrier, sealing is installed in the oil inlet hole slot 103
Ball 8,8 bottom end of the ball sealer are connected with adjustable spring 9, and internal diameter is small at the top and bottom of the use of oil inlet hole slot 103, intermediate internal diameter
Big pore passage structure, to make adjustable spring 9 be connected on the bottom end inner wall of oil inlet hole slot 103, ball sealer 8 is under normal circumstances
The external opening that oil inlet hole slot 103 is blocked under the elastic force effect of adjustable spring 9, to make dust not enter oil groove,
So that planetary gear lubricating oil when operating is not leaked out from the side of planet carrier 1, avoids the waste of lubricating oil.
When needing to add lubricating oil in planetary gear, the rifle mouth team of oil gun is chased after into the then rifle mouth of oil inlet hole slot 103
Crush seal ball 8 generates oil inlet gap, at this moment can be filled in lubricating oil in trapped fuel slot 102, and then gun adapter is extracted out, is stretched

As shown in Fig. 2, one end of the oil outlet 502 is pierced by out of planetary gear 5 tooth socket, oil outlet 502 is not from planet
There are two the reasons why being pierced by the side of wheel 5 and the gear teeth：
If oil outlet 502 is pierced by from the side of planetary gear 5, at this moment lubricating oil largely can all drip to the side of sun gear 3,
To make sun gear 3 and 5 intermeshing face of planetary gear that cannot lubricate, the effect of lubricating oil is very little；If oil outlet 502
Be pierced by from the gear teeth of planetary gear 5, gear-tooth strength can be made to reduce, once and gear be intermeshed when the larger gear teeth intensity of stress
Reduction is also easier to be worn, to make planetary service life greatly reduce.
According to above analysis, oil outlet 502 is pierced by the intensity for neither influencing gear tooth out of novel wheel 5 tooth socket,
And gear lubricant can be delivered directly to the site of engagement of sun gear 3 and planetary gear 5, and lubricating oil can also be transmitted to

When the noise that generates, planetary transmission efficiency is also because gear has obtained greatly improving due to timely lubrication.
The path that lubricating oil flows to each gear is：
As shown in Figure 1, when planet carrier 1 and planetary gear 5 rotate, some shunting oil duct 401 is located at trapped fuel slot
When 102 lower section, the gear lubricant being stored in trapped fuel slot 102 can flow into shunting due to gravity factor from scattered oilhole road 104
In oil duct 401, then since gravity is out of the instillation annulus of weeping pipe 402 oil groove 501, lubricating oil flows lubricating oil from oil outlet 502
The wheel flank of tooth of planet wheels 5, to be lubricated to each gear teeth of sun gear 3, planetary gear 5 and gear ring, abrasion is small, friction is damaged
The energy of mistake is small, the long transmission efficiency of gear life.
Preferably, the utility model does not have to opening planet carrier 1 can add lubricating oil to planetary gear, and add lubrication
The each planetary gear 5 of lubricating oil automatic stream and sun gear 3, save time and manpower after oil, easily quick.
As shown in Figure 1, the inside of the planet carrier 1 is equipped with bearing mounting groove 105, installed in the bearing mounting groove 105
There are the bearing 10 being set on the outside of 4 one end of planet jack-post, the left and right sides of the planetary gear 5 to be mounted on axial buffering device 6,
The axial buffering device 6 includes hollow rubber stick that is being fixedly mounted on 10 inside of bearing and being set on the outside of planet jack-post 4
601, hollow rubber stick 601 is internally provided with cylinder groove, and the internal diameter of cylinder groove is bigger than the outer diameter of planet jack-post 4, avoids rubber
Friction energy-dissipating when stick rotation with planet jack-post 4.
The hollow rubber stick 601 is embedded with buffer spring 602, the axis of the axis and hollow rubber stick 601 of buffer spring 602
It overlaps, buffer spring 602 is not only promoted the elastic buffer power of hollow rubber stick 601, makes hollow rubber stick 601 not
Easily because often rubbing against or squeezing and deformed damaged for planetary gear 5, also makes the rigidity of hollow rubber stick 601 get a promotion, make sky
The inside of rubber bar when planet wheels 5 rotate of heart rubber bar 601 is hardly contacted with the surface of planet jack-post 4, to
Keep the rotation of hollow rubber stick 601 more smooth.
Axial buffering device 6 is to the principle of planetary gear 5 into row buffering：
When planetary gear 5 is in rotation, since planetary gear 5 is unfixed, so planetary gear 5 can be frequently in planet jack-post
It horizontally slips on 4, at this moment planetary gear 5 will touch the hollow rubber stick 601 of its certain side, hollow rubber stick 601 and buffering
The power that horizontally slips of planetary gear 5 can be buffered and be uninstalled by spring 602, kept planetary gear 5 return in situ and worked normally, be expert at
When 5 side of star-wheel is contacted with hollow rubber stick 601, planetary gear 5 is because having frictional force, institute between hollow rubber stick 601
To revolve column with hollow rubber stick 601, and hollow rubber stick 601 is fixedly connected and rubber bar due to one end with 10 inner ring of bearing
Inside almost zero is contacted with planet jack-post 4, so the rotation of rubber bar 601 almost non-resistance, such planetary gear 5 horizontally slips loss
Energy can be reduced to minimum, and play the role of reducing noise almost without noise when rubber bar rubs with gear.
Preferably, axial buffering device 6 avoids the friction between planetary gear 5 and planet carrier 1, and hollow rubber stick
601 can rotate with planetary gear 5, both reduce noise, and the abrasion of planetary gear 5 and rotational energy loss is also made to be reduced to most
It is small, to reach protection planetary gear 5, improve effect and the purpose of the transmission efficiency of planetary gear 5.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
