Summary of the invention
Invent problem to be solved
As described above, although the free type twin-direction clutch of Fig. 7 A ~ Fig. 7 C is compact and reliably can controls the mechanical part of transmission of power, according to the difference of purposes, also leave and answer room for improvement.The present invention solves the problem of the following stated of this free type twin-direction clutch.
First, in the twin-direction clutch of Fig. 7 A ~ Fig. 7 C, undertaken by nipping of roller RO from input shaft to the transmission of power of output shaft, by the friction between roller RO and the internal surface of output block OM, input torque is delivered to outlet side.If the frictional force of the surface of contact of roller RO disappears, then can not carry out transmission of torque, therefore the transmitting torque of twin-direction clutch is subject to frictional force and reduces the restriction brought.
In addition, in order to make the rotation of input shaft be delivered to output shaft, needing to make input block IM rotate a little and push two intermediate member MM open as shown in Figure 7 B like that, making roller RO be connected to the internal surface of output block OM.The rotation of input block IM non-immediate becomes the rotation of output block OM, but so-called dead band is there is between input block IM and output block OM, and produce noise along with the abutting of parts.And if remove the driving torque of input block IM, then the input block IM spring TS and intermediate member MM that is stretched pushes back a little and reverses, and therefore whenever the driving torque removing input block IM, needs the position compensation that so-called 0 recovery is used.Accordingly, carry out when being folded with the such free type twin-direction clutch of Fig. 7 A ~ Fig. 7 C accurately positioning control, the structure of control system becomes complicated.

Multiple internal tooth is formed with, be formed with the valley of the internal tooth entering described cylinder part respectively at described actuator, identical with described internal tooth number of teeth external tooth at the inner peripheral surface of described cylinder part,
Be formed with the central aperture portion of section circle in the side of the axis of described actuator, and be formed with prominent axle at opposite side, and,
The eccentric part being located at the section circle of described output shaft is embedded in the described central aperture portion of described actuator, the described prominent axle of described actuator enters the hole portion being located at described input shaft, a part for the outer circumferential face of described prominent axle contacts with the wall in the described hole portion of described input shaft, and described actuator can revolve round the sun around described running shaft.
In addition, in the free type twin-direction clutch of other modes of the present invention, can be configured to, described cylinder part is embedded into via rolling bearing in the accommodation section of the section circle being located at described housing, multiple internal tooth is formed with, external tooth of with the described internal tooth number of teeth identical that be formed with the valley of the internal tooth entering described input shaft respectively at the described prominent axle of described actuator in the described hole portion being located at described input shaft.
In addition, in the free type twin-direction clutch of other modes of the present invention, can be configured to, the plectane portion being fixed on described input shaft is combined with in one end of the axis of described cylinder part, in described plectane portion, the described hole portion of section circle is provided with in the position of the rotating shaft center departing from described input shaft, and, the described prominent axle of the section circle entering described hole portion is provided with at described actuator.
In addition, preferably, on the opposed face of described input shaft and described output shaft, be formed with central axis at the central part of a side, and be formed with the center hole embedded for described central axis at the central part of the opposing party.
In addition, the spring rotation of described input shaft being given to restraining force can be provided with between described housing and described input shaft.
Invention effect
Free type twin-direction clutch of the present invention arranges the input shaft and output shaft that can rotate centered by common axis of rotation in not revolvable housing, in addition, the actuator being formed with multiple external tooth is made to combine with the cylinder part being formed with the internal tooth identical with these external tooth numbers of teeth and be contained in housing.Be formed with the central aperture portion of section circle in a side side of the axis of actuator, embed and be located at the eccentric wheel of output shaft, and form prominent axle at opposite side at this, this prominent axle enters the hole portion that is located at input shaft and contacts with the wall in hole portion.
When input shaft rotates, as described in detail afterwards, input shaft, cylinder part and actuator become lock state, and actuator and input shaft rotate around the running shaft of input shaft integratedly.Owing to embedding the eccentric wheel of output shaft in actuator, the running shaft of output shaft is identical with input shaft, and therefore, result is that input shaft is integrated with output shaft via actuator.Therefore, the rotation from the positive and negative direction of input shaft is delivered to output shaft by former state, and output shaft rotates to identical direction with identical rotating speed.
On the other hand, if output shaft rotates, the center then embedding the eccentric actuator of output shaft is moved (circular movement) around common axis of rotation, but is formed with multiple external tooth at actuator, and combines with the cylinder part being formed with the internal tooth identical with these external tooth numbers of teeth.Thus, actuator can not cause rotation but revolve round the sun, now, not to cylinder part effect rotating torques around common axis of rotation in cylinder part.Although the prominent axle of rotor enter input shaft hole portion and a part contact with the wall in hole portion, but it is identical with the relation of actuator and cylinder part, because they engage to allow the mode of revolution motion, therefore the revolution of actuator can not to output shaft effect rotating torques.In other words, even if output shaft rotates, actuator is also only revolve round the sun in cylinder part, and output shaft dallies, and the rotation of output shaft can not be passed to input shaft.
Like this, in free type twin-direction clutch of the present invention, utilize and allow the actuator of revolution motion and cylinder part, from input shaft to output shaft transferring power, and, output shaft is dallied and cut off on the contrary towards transmission.Make actuator, cylinder part be that lock state carries out to passing through of output shaft, and non-used frictional force, therefore transmitting torque not by frictional force reduce limit.Being about to produce immediately when driving from output shaft, therefore there is not dead band in the lock state of actuator etc., can save at 0 and restore position adjustment used.
In addition, different from the free type twin-direction clutch of Fig. 7 A ~ Fig. 7 C, in free type twin-direction clutch of the present invention, do not use and cut off extension spring used by transmitting from output shaft to the rotation of input shaft.The existence of spring causes the manufacture assembling operation of mechanical device to become difficulty sometimes, but the present invention does not exist this hidden danger.
In addition, free type twin-direction clutch of the present invention also can be, the accommodation section of cylinder part via the section circle of rolling bearing embedding housing of internal tooth will be formed, and, the prominent axle making the actuator being formed with external tooth combines with the hole portion of the input shaft being formed with internal tooth, makes it engage in the mode of the revolution motion allowing actuator.Because cylinder part and input shaft become independently parts, therefore the shape of cylinder part becomes simple, and it manufactures, the processing of internal tooth is comparatively easy.
In addition, free type twin-direction clutch of the present invention also can be, the plectane portion being fixed on input shaft is combined with in one end of the axis of cylinder part, the hole portion of section circle is set in the position at the center of departing from plectane portion, and makes in the mode of the revolution motion allowing actuator the prominent axle of the section circle of actuator be sticked in this hole portion.In this twin-direction clutch, cylinder part and input shaft can be set to single parts, number of components correspondingly reduces.And the structure of the engagement portion of actuator and input shaft becomes simple, manufacture processing and become easy.
In addition, free type twin-direction clutch of the present invention also can be, at a square one-tenth central shaft in the opposed face of input shaft and output shaft, forms center hole, and make central shaft chimeric with center hole the opposing party.So central shaft is supported on center hole by axle, input shaft and output shaft can be made stably to support and rotate.
In addition, free type twin-direction clutch of the present invention also can be arrange spring between housing and input shaft, gives restraining force to the rotation of input shaft.Input shaft is set to rotate, and becomes the prominent tactile state that is coupling with actuator, therefore in the rotation of output shaft, if actuator revolution, then causes interlock to rotate in the mode of the revolution interlock with actuator, there is the hidden danger that input shaft rotates.When giving restraining force by spring to input shaft, reliably can stop the rotation of such input shaft, preventing the rotation transmission from output shaft to input shaft.As long as the less power of the degree that the interlock that the restraining force that spring brings prevents friction etc. from bringing rotates is just enough.
And, according to other modes of the present invention, a kind of drive unit is provided, this drive unit possess above-mentioned each mode of the present invention free type twin-direction clutch, be linked to described input shaft driving source and be linked to described output shaft and the driving mechanism that drives via described output shaft transmission of rotation for making from described input shaft.
About the object of the invention described above, mode and effect, also have not by the object of the present invention of above-mentioned record, mode and effect, if those skilled in the art, then can understand mode (detailed description of invention) for implementing following invention by referring to the record of accompanying drawing and claims.

As shown in Figure 1A ~ Fig. 1 D, the free type twin-direction clutch of the 1st embodiment possesses input shaft 2 and the output shaft 3 of the central part of the housing 1 being configured at fixing section circle.Housing 1 is the cup part be made up of circumferential wall part and end plate, and has the discoideus shield 1S of shutoff inside in open end press-in.Input shaft 2 and output shaft 3 have common axis of rotation o, and this running shaft o is identical with the central shaft of housing 1.The center of the end plate of the through housing 1 of input shaft 2 and axle is supported on this, the center of the through shield 1s of output shaft 3 and axle is supported on this.As shown in the section C-C of Fig. 1 D, the more shallow recess being configured with C type ring 4 is located at the end plate of housing 1, and C type ring 4 plays function as contacting with input shaft 2 to the spring that certain restraining force is given in the rotation of input shaft 2.
In the inside of housing 1, the rolling bearing BR1 via the internal surface embedding circumferential wall part is provided with cylinder part 5.As shown in the section B-B of Fig. 1 C (also with reference to Fig. 4 A, Fig. 4 B as the monomer figure of cylinder part), the central shaft of cylinder part 5 is consistent with running shaft o, and within it side face is formed with multiple internal tooth 5t.Input shaft 2 is embedded with via rolling bearing BR2 in the end of a side of cylinder part 5, and, be embedded with in the end of opposition side for the through discoideus shield 5s of output shaft 3.
And, there is actuator 6 in the internal configurations of cylinder part 5, be formed with the external tooth 6t (also with reference to Fig. 4 C ~ Fig. 4 E as the monomer figure of actuator) of the identical number of teeth of the valley of the internal tooth 5t entering cylinder part 5 respectively in its periphery.The state that actuator 6 departs from e amount with its central shaft o ' distance running shaft o is configured at the inside of cylinder part 5.Thus, under the state of the section B-B of Fig. 1 C, become relative in upside, the external tooth 6t of actuator 6 enters the valley of the internal tooth 5t of cylinder part 5, in downside, external tooth 6t leaves internal tooth 5t.In other words, in actuator 6 not rotation but when relatively moving (revolution) with its central shaft o ' around running shaft o, the envelope that the outer circumferential face that the inner peripheral surface being formed with the cylinder part 5 of internal tooth 5t becomes the actuator 6 possessing external tooth 6t is formed.
Be provided with the prominent axle 6s being formed on the outer periphery multiple external tooth 6st in the end of the actuator 6 of input shaft 2 side, prominent axle 6s enters the hole portion 2r being located at input shaft 2.As shown in the cross section A-A of Figure 1B, in the hole portion 2r of input shaft 2, be formed with the internal tooth 2rt identical with the external tooth 6st number of teeth, the external tooth 6st of prominent axle 6s is using the valley (also with reference to Fig. 3 A ~ Fig. 3 C as monomer figure) of the internal tooth 2rt of the mode identical with the relation of the external tooth 6t of actuator 6 periphery and the internal tooth 5t of cylinder part 5 difference access aperture portion 2r.Be formed with the central aperture portion 6r of section circle in the end of output shaft 3 side of actuator 6, be embedded with the eccentric wheel 3s of the section circle being located at output shaft 3 at this central aperture portion 6r via rolling bearing BR3.The running shaft o of the centre distance output shaft 3 of eccentric wheel 3s leaves e amount (also with reference to Fig. 3 D ~ Fig. 3 F as monomer figure).
In addition, be provided with the central axis 3p extended towards input shaft 2 at the central part of output shaft 3, this central axis 3p, by the through hole 6h of actuator 6 central authorities, is embedded into the central hole 2h of the central part being formed at input shaft 2.Thus, input shaft 2 and output shaft 3 become the state that mutual axle supports, the inclination of axle when preventing rotation or the work of instability.
