The lubricating oil LB1 represented with thinner dot pattern is full of.In addition, space S P1 is via including the 1st the circulation path 72a and the 2nd the circulation path
The circulation path 72 of 72b is connected with baffle-box 70.
In addition, device for revolving and driving 40 has by planetary wheel carrier 46, the 2nd gear-box 52, the 3rd gear-box 54 and planetary wheel carrier
106 closed space S P2.In addition, oil sealing (not shown) is installed on planetary wheel carrier 106.Space S P2 accommodates sun gear
82nd, 102, planetary gear 84,104 and planetary wheel carrier 86,106, are full of by the lubricating oil LB2 represented with thicker dot pattern.Separately
Outside, lubricating oil LB2 is isolated by oil sealing 57 from lubricating oil LB1.In addition, lubricating oil LB2 can also be and lubricating oil LB1 identical types
Lubricating oil or different types of lubricating oil.For example, in device for revolving and driving 40, the lubricating oil LB1 of high rotation
Can also be the different types of lubricating oil of lubricating oil LB2 with low rotation.
As shown in fig. 6, in the case where output shaft 21b is static, the horizontal L1 of the pasta of the lubricating oil LB1 in baffle-box 70
The position high in the bottom surface than end plate 21a.That is, space S P1 is in the state being full of by lubricating oil LB1.In addition, the 2nd circulation
Road 72b is connected in the position of the horizontal L1 high than pasta with baffle-box 70.In addition it can also be configured to, make in baffle-box 70
The link position of 2 the circulation path 72b can adjust.
On the other hand, as shown in fig. 7, in the case of output shaft 21b is rotating, lubricating oil LB1 in space S P1 by by
The centrifugation pumping action that rotating planetary wheel carrier 46 and brake disc 60 are brought, the ostium quilt of the lower part by being formed in space S P1
It is sent into the circulation path 72.Specifically, the lubricating oil LB1 in space S P1 passes through between brake disc 60 and brake plate 62 by the 1st
The circulation path 72a is sent into, and is discharged to baffle-box 70.In addition, the dotted arrow of Fig. 7 represents the flowing of lubricating oil LB1.
In addition, oil circuit 74 is equipped with planetary wheel carrier 46, so as to the supply profit on the inside of the radial direction of brake disc 60
Lubricating oil LB1.By oil circuit 74, device for revolving and driving 40 can form the flowing of the lubricating oil LB1 on the surface along brake disc 60,
Brake disc 60 can efficiently be cooled down.In addition, in the present embodiment, 1 braking is configured between two brake plates 62
Disk 60, but the structure using multiple brake discs 60 can also be used.Specifically, can also use in each of 4 brake plates 62
The structure of 3 brake discs 60 is respectively configured between.In the case, device for revolving and driving 40 can promote to deposit by oil circuit 74
The circulation of lubricating oil LB1 in the space between two adjacent brake discs 60.In addition, oil circuit 74 can also extend to row
Near the rotation axis of star wheel frame 46, by one or more openings and a part of the space S P1 of the lower section in sun gear 42
Connection.
In addition, space S P1 due to lubricating oil LB1 a part by the 1st the circulation path 72a and discharged to baffle-box 70,
So the air in baffle-box 70 is sucked by the 2nd the circulation path 72b.As a result, the lubricating oil LB1 in space S P1 is returned
Convert motor 21 output shaft 21b Stirring and form the pasta L2 of mortar shape.In addition, the 1st the circulation path 72a and the 2nd
Unrestricted states of the circulation path 72b all in the flowing for not being throttled the limitation such as hole lubricating oil.
Then, by the lubricating oil LB1 discharged from space S P1, the pasta of the lubricating oil LB1 in baffle-box 70 reaches than
Horizontal L3 top 2 the circulation path 72b.In the case, the lubricating oil LB1 in baffle-box 70 passes through the 2nd the circulation path 72b and formation
Tap hole on the top of space S P1 is flowed into space S P1.In addition, tap hole is for example formed in the top or interior of internal gear 48
Portion.Lubricating oil LB1 in space S P1 is flowed into by internal gear 48, planetary gear 44, sun gear 42 and row from baffle-box 70
After star wheel frame 46 lubricates, collaborate with the lubricating oil LB1 in the space S P1 for the pasta L2 for forming mortar shape.
In addition, in baffle-box 70, the lubricating oil LB1 coolings that are provided with using baffle-box 70 as heat exchanger
The fan of an example of structure 76.Therefore, the temperature ratio for the lubricating oil LB1 being flowed into from baffle-box 70 in space S P1 is arranged from space S P1
The temperature gone out to the lubricating oil LB1 in baffle-box 70 is low.As a result, the lubricating oil LB1 energy in space S P1 is flowed into from baffle-box 70
Enough lubricating oil LB1 by internal gear 48, planetary gear 44, sun gear 42, planetary wheel carrier 46 and space S P1 are cooled down.In addition,
Heat exchange mechanism 76 can also be formed in the mechanism beyond the fans such as the radiating fin on the outer surface of baffle-box 70.In addition,
Baffle-box 70 is since its own can be used as heat exchange mechanism, so can also omit additional heat exchange mechanism 76.In addition,
Baffle-box 70 can also set jagged flow path in inside, so as to buffered from the 1st the circulation path 72a lubricating oil LB1 flowed into
Space S P1 is returned to after being reliably cooled in case 70, by the 2nd the circulation path 72b.In addition, baffle-box 70 can also possess energy
Enough adjust the refrigerator device of internal pressure.
Then, if the rotation of output shaft 21b stops, the lubrication in the space S P1 for the pasta L2 for foring mortar shape
Oily LB1 forms horizontal pasta in space S P1.Also, the lubricating oil LB1 in baffle-box 70 is due to because of planetary wheel carrier 46 and system
Centrifugal pump event resolves caused by the rotation of Moving plate 60, so by the 1st the circulation path 72a and the 2nd the circulation path 72b to space S P1
Return, until its pasta becomes lower than horizontal L3.In addition, the lubricating oil LB1 in baffle-box 70 becomes than horizontal L3 in its pasta
After low, returned by the 1st the circulation path 72a to space S P1, until its pasta reaches horizontal L1 (with reference to Fig. 6).If baffle-box 70
The pasta of interior lubricating oil LB1 reaches horizontal L1, then space S P1 becomes the state that is full of by lubricating oil LB1, sun gear 42,
Planetary gear 44, planetary wheel carrier 46 and internal gear 48 become the state being completely infused in lubricating oil LB1.
In this way, device for revolving and driving 40 rotary motor 21 output shaft 21b rotation when, by the profit in space S P1
Lubricating oil LB1 is discharged to baffle-box 70, reduces the amount of the lubricating oil LB1 in space S P1.As a result, device for revolving and driving 40 makes profit
The stirring resistance of lubricating oil LB1 reduces, and can make the rotation of output shaft 21b, sun gear 42, planetary gear 44, planetary wheel carrier 46
Load reduction.
In addition, device for revolving and driving 40 is caused by the rotation of planetary wheel carrier 46 and brake disc 60 by centrifuging pumping action,
Lubricating oil LB1 in the lower part of space S P1 is discharged to baffle-box 70.Also, device for revolving and driving 40 is by baffle-box 70
The top of from lubricating oil LB1 to space S P1 send back to.As a result, device for revolving and driving 40 can not make the lubricating oil in space S P1
The amount of LB1 exceedingly reduces and reliably lubricates sun gear 42, planetary gear 44, planetary wheel carrier 46 and internal gear 48.
In addition, device for revolving and driving 40 is cooled down the lubricating oil LB1 in baffle-box 70 by heat exchange mechanism 76.As a result,
Device for revolving and driving 40 can by space S P1 by rotation of each gear etc. and heated lubricating oil LB1 in baffle-box
Backward space S P1 is cooled down in 70 to send back to, can suppress the overheat of each gear and lubricating oil LB1.
On the other hand, output shaft 21b rotating feelings of the lubricating oil LB2 in space S P2 even in rotary motor 21
Under condition, it will not be circulated in space S P2 from lower to upper part.This is because since the rotary speed of each gear is used than revolution
The rotary speed of the output shaft 21b of motor 21 is low, so the reduction, lubricating oil LB2 for the rotary load of each gear is cold
But desirability is than relatively low.But the present invention is not limited to the structure.For example, device for revolving and driving 40 can also be in order to make
Lubricating oil LB2 circulations in space S P2, in addition in order to suppress the overheat of lubricating oil LB2, and possess with baffle-box 70 it is same with
Other baffle-box of space S P2 connections.
Then, the configuration example of the device for revolving and driving 40X of another embodiment of the present invention is illustrated with reference to Fig. 9.
In addition, the sectional view of state when Fig. 9 is the output shaft 21b rotations for representing rotary motor 21, corresponding to Fig. 7.
Device for revolving and driving 40X possesses in the combination of replacement baffle-box 70, the 1st the circulation path 72a and the 2nd the circulation path 72b
On this point of the circulation path 72M, is different from device for revolving and driving 40, but is common in terms of others.Therefore, common point is omitted
Explanation and describe difference in detail.
The circulation path 72M is in the 52 respective oil circuit being internally formed of the 1st gear-box 50 and the 2nd gear-box, even in revolution
With the output shaft 21b of motor 21 it is static in the case of be also full of by lubricating oil LB1.That is, space S P1 and the circulation path 72M always locate
In the state being full of by lubricating oil LB1.
In addition, as shown in figure 9, in the case of output shaft 21b is rotating, the lubricating oil LB1 in space S P1 passes through by rotating
Planetary wheel carrier 46 and the centrifugation pumping action that brings of brake disc 60, the ostium of the lower part in space S P1 by
The circulation path 72M is sent into.Specifically, the lubricating oil LB1 in space S P1 through brake disc 60 and brake plate 62 by circulation
Road 72M is sent into.The lubricating oil LB1 that is fed in the circulation path 72M by heat exchange mechanism 76 while cooled down, while being newly sent into
Lubricating oil LB1 is promoted and conveyed to vertical top.Then, the lubricating oil LB1 quilts of vertical top are moved in the circulation path 72M
The lubricating oil LB1 being newly sent into is promoted, the close direction by the tap hole towards the top for being formed in space S P1, i.e. with rotation axis
Conveying.At this time, the lubricating oil LB1 in space S P1 will be left by centrifugal force from rotation axis.Therefore, in the circulation path 72M to connecing
The lubricating oil LB1 of direction movement of rotation axis is bordering on while will be connect from the lubricating oil LB1 that the rotation axis is left to rotation axis
Near direction pushes back, while being released from the tap hole on the top for being formed in space S P1 into space S P1.In addition, the void of Fig. 9
Line arrow represents the flowing of the lubricating oil LB1 moved in the circulation path 72M.
In this way, space S P1 receives lubricating oil with the amount for the lubricating oil LB1 being fed in the circulation path 72M from the circulation path 72M
LB1.Therefore, space S P1 is always at the state being full of by lubricating oil LB1, passes through the output shaft 21b's of rotary motor 21
Rotation is stirred, but not forms the pasta of mortar shape.
Then, if the rotation of output shaft 21b stops, the lubricating oil LB1 in the circulation path 72M stops its movement.Herein
In the case of, space S P1 is not also changed by the state that lubricating oil LB1 is full of.
In this way, device for revolving and driving 40X makes the profit in space S P1 in the output shaft 21b rotations of rotary motor 21
Lubricating oil LB1 is circulated upward from below.Specifically, device for revolving and driving 40X passes through by planetary wheel carrier 46 and brake disc 60
The centrifugation pumping action that brings is rotated, using by the ostium in the lower part of space S P1 and the outflow in the top of space S P1
The circulation path 72M that hole is connected circulates lubricating oil LB1.In addition, device for revolving and driving 40X by heat exchange mechanism 76 by the circulation path
Lubricating oil LB1 coolings in 72M.As a result, device for revolving and driving 40X can will pass through rotation of each gear etc. in space S P1
Heated lubricating oil LB1 is sent back to after being cooled down in the circulation path 72M to space S P1, can suppress each gear and lubricating oil LB1's
Overheat.
On the other hand, output shaft 21b rotating feelings of the lubricating oil LB2 in space S P2 even in rotary motor 21
Condition, will not circulate in space S P2 from lower to upper part.This is because since the rotary speed of each gear is than revolution electricity consumption
The rotary speed of the output shaft 21b of motivation 21 is low, so reduction, the cooling of lubricating oil LB2 for the rotary load of each gear
Desirability than relatively low.But the present invention is not limited to the structure.For example, device for revolving and driving 40X can also be in order to make sky
Between lubricating oil LB2 circulations in SP2, in addition in order to suppress the overheat of lubricating oil LB2, and possess it is same with the circulation path 72M and
Other the circulation path of space S P2 connections.
In addition, device for revolving and driving 40X is configured to, no matter output shaft 21b rotations of rotary motor 21 or static,
All space S P1 is always full of with lubricating oil LB1.Therefore, though the inclination of the body of device for revolving and driving 40X excavators why
Sample, can reliably lubricate sun gear 42, planetary gear 44, planetary wheel carrier 46 and internal gear 48.
