In, the planet pinion 4 of the upside in Fig. 1 is made up of above-mentioned two gear sheets that can be rotated against, in following explanation
In, the planet pinion is denoted as the 1st planet pinion 4P.
Above-mentioned sun gear 2 and ring gear 3 are engaged with planet pinion 4P all the time, and with previously known herringbone bear one
Sample ground is constituted, so as to cause the component on axis direction corresponding with the moment of torsion of transmission to cancel out each other.Specifically formed
For the tooth of the side on axis direction is contrary with the tooth helical angle of opposite side.In addition, sun gear 2 is formed with described later and planet
1st external tooth 7 and the 2nd external tooth 8 of little gear 4P engagement.Also, ring gear 3 is formed with the 1st engaged with planet pinion 4P
Internal tooth 9 and the 2nd internal tooth 10.Additionally, helical angle refers to that pitch wheel does not produce the nodal section and tooth of slip in engagement
The angle that the intersection of the flank of tooth of wheel, i.e. tooth trace are inclined relative to axis direction.
On the other hand, as shown in Fig. 2 planet pinion 4P is by two gear sheets 11,12 for being held in same pinion shaft 5
Constitute, and be formed as the helical angle and the gear sheet of the opposing party of the tooth of the gear sheet (being denoted as the 1st gear sheet below) 11 of a side
The helical angle of (being denoted as the 2nd gear sheet below) 12 is contrary.That is, the 1st gear sheet 11 is adjacent on the same axis with the 2nd gear sheet 12
And configure, the entirety (unit) of the shape of the tooth after the 1st gear sheet 11 is combined with the 2nd gear sheet 12 is formed as herringbone bear.
Additionally, be respectively arranged with the 1st gear sheet 11 and the 2nd gear sheet 12 the 1st gear sheet 11 is supported bearing 16,
And the bearing 16 supported by the 2nd gear sheet 12, the 1st gear sheet 11 and the 2nd gear sheet 12 are via these bearings 16
And can be rotated against relative to pinion shaft 5.
Above-mentioned two gear sheets 11,12 are carried out more specifically bright, the 1st gear sheet 11 is formed with rotary shaft 13
Axis direction on have specific length the 3rd external tooth 14, similarly, the 2nd gear sheet 12 is formed with the axis in rotary shaft 13
There is on direction the 4th external tooth 15 of specific length.In addition, these each teeth 14,15 as described above with specify helical angle and shape
Into, the external tooth 14 for being formed at the 1st gear sheet 11 and the external tooth 15 for being formed at the 2nd gear sheet 12 with reciprocal helical angle shape
Into.Also, the 1st gear sheet 11 is configured to be rotated against with the 2nd gear sheet 12.And, the of the 1st gear sheet 11
3 external tooths 14 are configured to the 1st external tooth 7 with above-mentioned sun gear 2 and the 1st internal tooth 9 of ring gear 3 is engaged, similarly, the 2nd tooth
4th external tooth 15 of wheel piece 12 is configured to the 2nd external tooth 8 with sun gear 2 and the 2nd internal tooth 10 of ring gear 3 is engaged.Additionally, phase
It is the rotation of the degree of the error for referring to the phase place for adjusting the 1st gear sheet 11 and the 2nd gear sheet 12 to rotation.In addition, including
Planet pinion 4P be configured with interior planet pinion 4 in a circumferential direction multiple, but as long as a planet at least within
Little gear 4 (4P) is made up of two gear sheets 11,12, and other planet pinions 4 (4P) can be with sun gear 2 and internal tooth
Circle 3 is similarly made up of herringbone bear.Also, during a side of sun gear 2 or ring gear 3 is equivalent to embodiments of the invention
1st rotate element, pinion frame 6 equivalent to embodiments of the invention in the 2nd rotate element, sun gear 2 or ring gear 3
The opposing party equivalent to embodiments of the invention in the 3rd rotate element.
In addition, as described above, the planet pinion 4P of planetary gearsets 1 involved in the present invention is by 11 He of the 1st gear sheet
2nd gear sheet 12 is constituted, and can assemble planetary gearsets 1 using herringbone bear.Specifically, by the planet pinion of segmentation
The gear sheet 11 of one side of 4P, (12) are assembled in sun gear 2, then make ring gear 3 and engage with the gear sheet 11, (12) that first assemble
And insert from axis direction.Next, making the gear sheet 12 of the opposing party of the planet pinion 4P of segmentation, (11) relative to a side
Cutting plate 11, (12) engage and insert from opposition side with sun gear 2 and ring gear 3 in the axial direction, thus, it is possible to group
Fill the planetary gearsets 1.
According to the present invention, as shown in Fig. 2 planet pinion 4P is constituted by the 1st gear sheet 11 and the 2nd gear sheet 12, so as to
Phase error can be absorbed because the 1st gear sheet 11 can be rotated against with the 2nd gear sheet 12.Specifically, for example
In the case where each tooth 9,10 of each tooth 7,8 and ring gear 3 of sun gear 2 deposits error (phase difference) in a rotational direction,
1st gear sheet 11 can be rotated against with the 2nd gear sheet 12, and therefore the phase place of planet pinion 4P is confirmed as sun gear
2 phase places that can be contacted simultaneously respectively with the flank of tooth of planet pinion 4P.In addition, the flank of tooth of planet pinion 4P and ring gear 3
Being also determined as can respectively while the phase place of contact.As a result, the error on above-mentioned direction of rotation is absorbed.That is, due to
Phase error can be absorbed, therefore, it is possible to make planetary gearsets 1 assembling when structure simplify.
Further, since planet pinion 4P is supported by pinion frame 6, therefore directly will not be changed into being input into key element, output
Key element and reaction force key element, also, as described above, planet pinion 4P transmits torsion between sun gear 2 and ring gear 3
Square, even if therefore in the case where sun gear 2, ring gear 3 have the deviation of phase place, it is also possible to adjust respective phase place.Therefore,
In the present invention, can be by not formed the main cause ground structure of above-mentioned problem to constitute planet pinion 4P by way of splitting
Into planetary gearsets 1.
The thrust load being subject to from ring gear 3 according to the structure of Fig. 1 and Fig. 2, planet pinion 4P and planet pinion 4P
The thrust load being subject to from sun gear 2 is in rightabout in the axial direction.In the case, by by moment of torsion be input into appoint
The rotate element of meaning so that pinion shaft 5 is reduced with the inevitable gap (clearance) of bearing 16.That is, by the gap
Reduce, so that planet pinion 4P is inclined relative to rotary shaft 13.In addition, being inclined such that sun gear 2 and planet because of this
The engagement of little gear 4P and ring gear 3 are changed with engaging for planet pinion 4P, above-mentioned are subject to from ring gear 3
Thrust load and the thrust load being subject to from sun gear 2 change relative to prespecified value.For example from ring gear 3
In the case that the thrust load being subject to reduces, the thrust load being subject to from sun gear 2 increases.And, after the variation from the sun
2 thrust loads that are subject to of wheel with change after the thrust load being subject to from ring gear 3 residual quantity thrust load by little for planet tooth
Wheel 4P is by the side for pressing to axis direction.
In addition, in the case where the bearing 16 supported by planet pinion 4P is taper roll bearing, with planet
Little gear 4P is inclined relative to rotary shaft 13 in the above described manner, constitutes the rolling element (roller) of taper roll bearing relative to rotation
Axle 13 inclines (also referred to as skewness).Additionally, the deflection is correspondingly changed with the amount in above-mentioned gap, i.e. if the amount in gap increases
Greatly, then the amount of deflection also increases sometimes.Thrust load is caused to act on planet because producing the skewness of this bearing 16 little
Gear 4P.
In the case where direction above-mentioned, that also input has the moment of torsion of any thrust load is fixed, can determine or in advance
Survey the direction that these thrust loads play a role.Therefore, according to the structure of Fig. 1 and Fig. 2, the hand of spiral of tooth is defined as so that
Act on the thrust load on the axis direction of the 1st gear sheet 11 and act on the thrust on the axis direction of the 2nd gear sheet 12
Load is acted on to the direction for causing them close to each other, thus, it is possible to offsetting (elimination) or reducing the thrust load.
In addition, can be offset by the simple structure of hand of spiral of regulation tooth etc. in the above described manner or reduce thrust
Load, so as to bear the structure of thrust load without the need for thrust bearing etc., simplifies can the structure of 1 entirety of planetary gearsets.And
And, due to can offset or reduce thrust load by this structure simultaneously, therefore, it is possible to suppressing or reducing because of the 1st gear sheet
11 side is contacted with the inner surface of pinion frame 6 with the inner surface of pinion frame 6 or the side of the 2nd gear sheet 12
And the power loss for causing.
On the other hand, when in the 1st gear sheet 11 with transmitting torque on 12 detached direction of the 2nd gear sheet, the 1st gear sheet
11 side is possible to contact with the inner surface of pinion frame 6, in addition, the side of the 2nd gear sheet 12 is possible to and planet tooth
The inner surface contact of wheel carrier 6.In this case, the resistance to sliding on the contact surface becomes main cause and is likely to result in moving
Power loss increase.Therefore, in the planetary gearsets 1 shown in Fig. 3, be configured to the 1st gear sheet 11 and the 2nd gear sheet 12 point
From being limited.
Specifically, be provided with limiting unit 17, when the 2nd gear sheet 12 to move from the detached direction of the 1st gear sheet 11 when,
In the side of the 2nd gear sheet 12, the side of the opposition side in the face opposed with the 1st gear sheet 11 is contacted with the limiting unit.The limiting unit
17 are configured to so that act on the load of the axis direction of the 1st gear sheet 11 because of 11 transmitting torque of the 1st gear sheet and because of the 2nd
12 transmitting torque of gear sheet and the load that acts on the axis direction of the 2nd gear sheet 12 are offset as internal force.Shown in Fig. 3
In example, cylindrical portion 18 is formed with the 1st gear sheet 11, the cylindrical portion 18 is stretched out and be supported to energy to 12 side of the 2nd gear sheet
Enough rotated against relative to pinion shaft 5.In addition, the inner peripheral surface for being configured to the 2nd gear sheet 12 is outer with the cylindrical portion 18
Side face is fitted together to.Also, cylindrical portion 18 be formed as length more than the 2nd gear sheet 12 axial length, so as to the cylindrical portion 18 top from
The side of the 2nd gear sheet 12 projects, and the limiting unit 17 and its top as flange part links.The limiting unit 17 for example can by with
The nut that the top of cylindrical portion 18 the screws togather locating snap ring chimeric with the top of cylindrical portion 18 is constituted.Furthermore, it is possible to make the 2nd tooth
After wheel piece 12 is chimeric with cylindrical portion, limiting unit 17 is formed by the riveting processing pressed by the top to cylindrical portion 18.
As long as can cause the load acted on the axis direction of the 1st gear sheet 11 and the 2nd gear sheet 12 mutual as described above
Offset, therefore, it can be configured to, cylindrical portion 18 is formed in the 2nd gear sheet 12 and make the 1st gear sheet 11 and the cylindrical portion
18 are fitted together to.
According to the structure of Fig. 3, the thrust load relative to axis direction can be suppressed.That is, the 1st gear sheet 11 has to the
The 18, the 2nd gear sheet 12 of cylindrical portion that 2 gear sheet, 12 side is stretched out is chimeric with cylindrical portion 18, and carrying out restriction using limiting unit 17 prevents
1st gear sheet 11 is separated with the 2nd gear sheet 12.That is, the amount of movement on axis direction is constrained using limiting unit 17.Thus, for example
Even if the 1st gear sheet 11 and the 2nd gear sheet 12 respectively away from direction on produce thrust load in the case of, it is also possible to so that
The thrust load is cancelled out each other as the internal force of planet pinion 4P.As a result, can suppress or reduce because of the little tooth of planet
Side contact with the inner surface of pinion frame 6 of wheel 4P and the resistance to sliding that causes.Additionally, the 2nd gear sheet 12 and cylinder
Portion 18 rotates against faint and shows greatly the rotation of identical rotating speed, therefore, hardly produces the side of the 2nd gear sheet 12
With the resistance to sliding at the contact surface of the side of limiting unit 17.
In addition, by constituting in like fashion, the quantity of bearing 16 can be reduced compared with the structure of above-mentioned Fig. 2.That is, exist
In the structure of Fig. 2, the bearing 16 supported respectively by the 1st gear sheet 11 and the 2nd gear sheet 12 is provided with, but according to the knot
Structure, is formed as the only construction supported by the 1st gear sheet 11 for becoming basic components, and planet pinion 4P will can be carried out
The bearing 16 of supporting is suppressed to one such that it is able to be greatly reduced cost.In other words, simplify can supporting member, therefore
Simplify can the construction of 1 entirety of planetary gearsets.Further, since the 2nd gear sheet 12 faint with rotating against for cylindrical portion 18,
And show greatly the rotation of identical rotating speed, therefore, hardly produce the outer peripheral face of the inner peripheral surface with cylindrical portion 18 of the 2nd gear sheet 12
Contact surface at resistance to sliding.
In addition, the planetary gearsets of the present embodiment can also be using the planetary gearsets 19 of double pinion as object, the row
Star gear train 19 is configured to the planet pinion 4a (being denoted as inner planet little gear 4a below) and the sun of the radially inner side shown in Fig. 4
The planet pinion 4b (being denoted as outer planet little gear 4b below) of 2 engagement of wheel and radial outside is little with ring gear 3 and inner planet
Gear 4a is engaged.In the case, if at least in inner planet little gear 4a and outer planet little gear 4b at least one party row
