In the following, being illustrated to the movement of the 1st geared system 100 of above structure.Here, illustrating the 1st outer toothed portion
132, the number of teeth of the 2nd outer toothed portion 134 and the 2nd interior teeth portion 156 is the case where number of teeth of the 100, the 1st interior teeth portion 142 is 102.
In the shape that two position of the 2nd outer toothed portion 134 on elliptical long axis direction is engaged with the 1st interior teeth portion 142
Under state, rotated if playing vibration body axis 112, the position of engagement of the 1st interior teeth portion 142 and the 2nd outer toothed portion 134 is also circumferentially moved therewith
It is dynamic.Since the number of teeth of the 1st interior teeth portion 142 is different from the number of teeth of the 2nd outer toothed portion 134, at this time the 2nd outer toothed portion 134 relative to
1st interior teeth portion 142 is rotated.Since the 1st internal gear 140 and the 1st bearing holder (housing, cover) 164 are in stationary state, the 2nd outer toothed portion
134 rotations are equivalent to the amount of its teeth number difference between the 1st interior teeth portion 142.That is, the rotation for playing vibration body axis 112 is substantially slowed down
After export to the 2nd outer toothed portion 134.Its reduction ratio is as follows.
Reduction ratio=(number of teeth of 1 interior teeth portion 142 of the number of teeth-the of the 2nd outer toothed portion 134)/the 2nd outer toothed portion 134 number of teeth
=(100-102)/100
=-1/50
Since the 1st outer toothed portion 132 is formed as one with the 2nd outer toothed portion 134, the 1st outer toothed portion 132 and the 2nd outer toothed portion
134 integrally rotate.Since the number of teeth of the 1st outer toothed portion 132 is identical as the number of teeth of the 2nd interior teeth portion 156, will not occur opposite
Rotation, the 1st outer toothed portion 132 are integrally rotated with the 2nd interior teeth portion 156.Therefore, rotation identical with the rotation of the 2nd outer toothed portion 134
It exports to the 2nd interior teeth portion 156.Subtract as a result, exporting the rotation of vibration body axis 112 by output device 14 from the 2nd internal gear 150
Rotation after speed to -1/50.
Then, the 2nd geared system is illustrated.
Fig. 3 is the cross-sectional view of the 2nd geared system 200 of gear device series involved in embodiment.
2nd geared system 200 has component parts identical with the 1st geared system 100.2nd geared system 200 has wave
Dynamic generator 110, external gear 130, the 1st internal gear 240, the 2nd internal gear 250, two including main part 252 and extension 154
A limiting component 160, base bearing 162, the 1st bearing holder (housing, cover) 164 and the 2nd bearing holder (housing, cover) 166.In addition, in the 1st geared system 100 and the 2nd
In geared system 200, the identical constitutive requirements of symbol are the general (shapes in the 1st geared system 100 and the 2nd geared system 200
And size is identical) constitutive requirements.Therefore, other than the 1st internal gear and the 2nd internal gear, the 1st geared system 100 and the 2nd tooth
Wheel apparatus 200 has identical constitutive requirements.Hereinafter, the emphasis pair point different from the 1st geared system 100 is illustrated.
Structure of the structure substantially with the 1st internal gear 140, the 2nd internal gear 150 of 1st internal gear 240, the 2nd internal gear 250
Identical, still, the number of teeth of the 1st interior teeth portion 242 of the 1st internal gear 240 is identical as the number of teeth of outer toothed portion, and the of the 2nd internal gear 250
The number of teeth of 2 interior teeth portions 256 is more than outer toothed portion and the number of teeth of the 1st interior teeth portion 242.
About the 1st bearing holder (housing, cover) 164, it is embedded in output device 14 by being latched and bolt is inserted into screw hole H, from
And bolt is fixed on output device 14.About the 2nd bearing holder (housing, cover) 166, fixation wall 12 is embedded in and by bolt by being latched
It is inserted into screw hole H, so that bolt is fixed on fixation wall 12.Therefore, in the 2nd geared system 200, the 1st internal gear 240 is installed on
The 14, the 2nd internal gear 250 of output device is installed on fixation wall 12.Therefore, in the 2nd geared system 200, rotation after deceleration from
The output of 1st internal gear 240.In addition, as shown in phantom in figure 4, fixation wall 12 can also be directly mounted at the 2nd internal gear 250.
External gear 130 is assembled into, the 1st outer toothed portion 132 by the 1st interior teeth portion 242 of the 1st internal gear 240 surround and with the 1st in
Teeth portion 242 engages, and the 2nd outer toothed portion 134 is surround and engaged with the 2nd interior teeth portion 256 by the 2nd interior teeth portion 256 of the 2nd internal gear 250,
That is, the 1st outer toothed portion 132 and the 1st interior teeth portion 242 of the 1st internal gear 240 of the rotation after output deceleration that teeth directional correction amount is bigger
Engagement.Therefore, in the 1st geared system 100 and the 2nd geared system 200, the 1st outer toothed portion 132 and the 2nd outer toothed portion 134 and the 1st
Meshing relation between internal gear and the 2nd internal gear is opposite.Specifically, the manufacturing process of the 1st geared system 100 includes
External gear 130, which is assembled into, to be engaged the 1st outer toothed portion 132 with the 2nd interior teeth portion 156 of the 2nd internal gear 150 and makes the 2nd outer toothed portion
134 processes engaged with the 1st interior teeth portion 142 of the 1st internal gear 140, the manufacturing process of the 2nd geared system 200 include by external tooth

Under, it is rotated if playing vibration body axis 112, the position of engagement of the 2nd interior teeth portion 256 and the 2nd outer toothed portion 134 is also circumferentially moved therewith.
Since the number of teeth of the 2nd interior teeth portion 256 is different from the number of teeth of the 2nd outer toothed portion 134, the 2nd outer toothed portion 134 is relative to the 2nd at this time
Interior teeth portion 256 is rotated.Since the 2nd internal gear 250 and the 2nd bearing holder (housing, cover) 166 are in stationary state, the 2nd outer toothed portion 134
Rotation is equivalent to the amount of its teeth number difference between the 2nd interior teeth portion 256.That is, the rotation for playing vibration body axis 112 is defeated after substantially being slowed down
Out to the 2nd outer toothed portion 134.Its reduction ratio is identical as the reduction ratio in the 1st geared system 100.
Since the 1st outer toothed portion 132 is formed as one with the 2nd outer toothed portion 134, the 1st outer toothed portion 132 and the 2nd outer toothed portion
134 integrally rotate.Since the number of teeth of the 1st outer toothed portion 132 is identical as the number of teeth of the 1st interior teeth portion 242, will not occur opposite
Rotation, the 1st outer toothed portion 132 are integrally rotated with the 1st interior teeth portion 242.Therefore, rotation identical with the rotation of the 2nd outer toothed portion 134
It exports to the 1st interior teeth portion 242.Subtract as a result, exporting the rotation of vibration body axis 112 by output device 14 from the 1st internal gear 240

Touching, so that gear wear.Also, since external gear 130 and the number of teeth internal gear different from the number of teeth of external gear 130 are with its engagement
The mode of positional shift carries out relative rotation, therefore, compared with the mutually the same situation of the number of teeth, wears bigger.Therefore, if from tooth
Rotation after the number internal gear output deceleration different from the number of teeth of external gear 130, then may result in the internal gear and external gear
130 excessive wears.In contrast, gear device series involved according to the present embodiment, are needing to export from the 2nd internal gear
The 1st geared system 100 is used when rotation after deceleration, then uses the 2nd in the rotation after needing to slow down from the output of the 1st internal gear
Geared system 200, as a result, from the rotation Shi Junneng after any one internal gear output deceleration in the 1st internal gear and the 2nd internal gear
The rotation after slowing down from the number of teeth internal gear output different from the number of teeth of external gear 130 is avoided, enough so as to avoid generating tooth
The excessive wear of wheel.

The 1st outer toothed portion 132 slow down with output after the interior teeth portion of internal gear of rotation engage.Thereby, it is possible to mitigate in the 1st outer toothed portion
The end thereof contacts load that 132 facewidth end generates, so as to mitigate the rotation after the 1st outer toothed portion 132 is slowed down with output
The abrasion that the interior teeth portion of internal gear generates.Therefore, the 1st interior teeth portion in the 1st internal gear can be made corresponding with external gear 130
It the abrasion that is generated between outer toothed portion and is produced between the 2nd interior teeth portion outer toothed portion corresponding with external gear 130 of the 2nd internal gear
Raw abrasion reduces same degree.
As described above, the rotation after slowing down can either be exported from the 1st internal gear while inhibiting gear to generate excessive wear
Turn that the rotation after slowing down can be exported from the 2nd internal gear again, it is thus possible to improve the installation freedom degree relative to object-based device.
Also, the gear device series according to involved in embodiment, external gear 130 need to change assembling direction and can lead to
With (although different objects, its design shape is identical), therefore, in the 1st geared system 100 and the 2nd geared system 200,
The main part that the 1st internal gear and the 2nd internal gear need to only be changed can construct series, therefore can provide tooth with relatively low cost
Wheel apparatus series.
