Crossed roller bearing can be replaced using the other kinds of bearing such as ball bearing or roller bearing.
When multiple planetary rollers 20 are revolved round the sun with the second rotating speed after deceleration, multiple planet carrier pins 60 are also therewith concomitantly with rotation
Rotated centered on shaft axis 9 with the second rotating speed.Also, when multiple planet carrier pins 60 are rotated with the second rotating speed, it is fixed on planet
The wheel 70 of frame pin 60 is also rotated centered on rotation axis 9 with the second rotating speed.Thus, wheel is driven.
Relieving mechanism 80 is the mechanism for pulling open inner ring 30 from planetary rollers 20.It such as can not drive motor 10 because of power-off etc.
When moving and needing manually to make the rotation of wheel 70, operated release mechanism 80.As shown in figures 1 and 3, the machine for releasing of an embodiment
Structure 80 has hook screw 81, nut 82, rope 83, multiple pulleys 84, action bars 85 and be hinged clamp mechanism 86.
Hook screw 81 is by from input side Insertion action point 313, and the application point 313 is in the outer peripheral edge of the first ring component 31
A part different from above-mentioned fulcrum 312.The outlet side to the first ring component 31 that nut 82 is installed on hook screw 81 is prominent
End.Thus prevent the hook screw 81 from being come off to input side.The one end of rope 83 is fixed on hook screw 81.Also, 83 quilts of restricting
Drawn and via multiple pulleys 84 from hook screw 81 to the input side of installing plate 200, and the other end of rope 83 is fixed on peace
Loading board 200.
Action bars 85 configures in a manner of terminal part is against the rope 83 being set up between multiple pulleys 84.Slow down dress in wheel
When putting 300 driven, action bars 85 is configured at the retreating position (Fig. 1 and Fig. 3 position) for not pressing rope 83.In the state
Under, the length that 83 ratio installing plate 200 extends to outlet side of restricting.Therefore, the first ring component 31 is because of the pressure of helical spring 41
Power and contacted with multiple planetary rollers 20.
On the other hand, when it is desirable that rotating wheel 70 by external force, the bar 861 of be hinged clamp mechanism 86 is operated, and makes operation
Bar 85 protrudes.Fig. 4 is the longitudinal section of the wheel unit 1 when making the protrusion of action bars 85.As shown in figure 4, protrude action bars 85
When, 83 length that extends to outlet side of ratio installing plate 200 of restricting shortens.Therefore, overcome the pressure of helical spring 41 and make first
The application point 313 of ring component 31 shifts to input side.As a result, the quilts of 20 and first ring component of planetary rollers 31 multiple in the axial direction
Pull open.
At this moment, the fulcrum 312 of the first ring component 31 contacts with branch point contact 53.Moreover, the first ring component 31 is with fulcrum
Relative to the planar tilt orthogonal with rotation axis 9 centered on 312.Like this, only by making the outer peripheral edge of the first ring component 31
A part displacement, just can from whole planetary rollers 20 pull open the first ring component 31.
Like this, in the wheel in deceleration device 300, when it is desirable that rotating wheel 70 by external force, release can be passed through
Mechanism 80 pulls open the first ring component 31 from multiple planetary rollers 20.Thus, a part for reducing gear is cut off.Therefore, it is possible to drop
It is low wheel 70 is rotated required external force.Also, the contact site of planetary rollers 20 and the first ring component 31 is not being engaged with each other for gear,
But do not have irregular face to be in contact with each other.Therefore, only by making the first ring component 31 minutely shift, planetary rollers can just be cut off
20 and first ring component 31.
The structure of relieving mechanism 80 can also need not be identical structure with an embodiment.But such as an embodiment
It is shown, if making the direction that pressing mechanism 40 presses the direction of the first ring component 31 and relieving mechanism 80 shifts the first ring component 31
It is axial direction, then easily simplifies the structure of pressing mechanism 40 and relieving mechanism 80.
The multiple pulleys 84 and be hinged clamp mechanism 86 of relieving mechanism 80 are installed on casing 50.Also, in operation toggle clamp machine
During structure 86, the action bars 85 as movable part shifts relative to casing 50.That is, the position of action bars 85 two resting positions it
Between switch.When no matter action bars 85 is switched to Fig. 1 resting position or switching to Fig. 4 resting position, toggle clamp machine
Structure 86 can make action bars 85 stably static.It is therefore not necessary to power constantly is applied to action bars 85, just can be by first
Ring component 31 maintains any state in the state contacted with planetary rollers 20 and the state separated from planetary rollers 20.
More than, the exemplary embodiment of the present invention is illustrated, but the invention is not restricted to above-mentioned one implementation
Mode.

Cam 87A is configured between two ring component 32A.Cam 87A has major diameter 871A and minor axis 872A, and cam 87A can be with footpath
Rotated centered on to the pivot center 870A of extension.
In wheel during deceleration device 300A drivens, as shown in figure 5, being configured in a manner of minor axis 872A is towards axial direction convex
Take turns 87A.In this condition, both the first ring component 31A and the second ring component 32A do not contact with cam 87A.Therefore, first
Ring component 31A and the second ring component 32A are contacted with planetary rollers 20A without being hindered by cam 87A.
On the other hand, when it is desirable that being rotated the wheel to by external force, cam 87A is made to rotate 90 centered on pivot center 870A
Degree.Cam 87A rotation can for example be realized by operating the bar being connected with cam 87A (omit and illustrate).Thus, such as Fig. 6
It is shown, configure cam 87A in a manner of major diameter 871A is towards axial direction.Like this, cam 87A major diameter 871A both ends and the
One ring component 31A and the second ring component 32A contacts, so as to strut the axially spaced-apart of two parts.In the example of fig. 6, spiral shell is overcome
Revolve spring 41A pressure and the first ring component 31A application point 313A is shifted to input side.As a result, the first ring component
31A is tilted, so as to which multiple planetary rollers 20A and the first ring component 31A is opened.Thereby, it is possible to reduce rotate the wheel to it is required outer
Power.
Also, in addition to an above-mentioned embodiment and Fig. 5~Fig. 6 example, the portion being combined with as rigid body can also be used
Linkage of part etc. from planetary rollers pulls open the first ring component.Also, it can also make the first ring component not obliquely to input
Side shifts.Also, in the example of above-mentioned an embodiment and Fig. 5~Fig. 6, manually action bars moves relieving mechanism
Make.But it is also possible to act relieving mechanism using the power of motor etc..
Also, in an above-mentioned embodiment and Fig. 5~Fig. 6 example, by making the displacement of the first ring component cut off row
