The gear motor of the 1st example of the present invention as shown in Figure 1, comprise: the AC motor 1 that becomes drive source, be connected, be driven rotating output shaft 3 by gear train 2 with the rotor 11 of AC motor 1, engage, interrupt the 1st clutch member 4 that is connected of output shaft 3 and rotor 11, and be configured in reducing gear train interlock between rotor 11 and the output shaft 3, become the clutch control lever 41 that engages, disconnects the clutch switching device shifter that switches the 1st clutch member 4.In addition, the gear motor of this example has the planetary gears 22 that becomes the 2nd clutch member that engages, disconnects between clutch output shaft 3 and the rotor 11, reaches the clutch operating mechanism 5 that the 2nd clutch member is engaged, disconnects.These each mechanisms are accommodated in case body 12a and reach in the casing 12 that is made of box cover 12b.
As Fig. 2 (A) and (B), the 1st clutch member 4 is by the rotor 11 that becomes the 1st clutch member and is formed at a plurality of (being 4 in this example) claw 11d above this rotor 11, is configured in output shaft 3 one sides, becomes the clutch pinion 21 of the 2nd clutch member and a plurality of (being 4 in this example) claw of being formed at below this clutch pinion 21 is constituted.
Shown in Fig. 1 and Fig. 2 (A), the structure of the 1st clutch member 4 is to live clutch gear 21 and be pressed down because of the crest part that is formed at the cam surface 41a on the clutch control lever 41.In case after depressing like this, clutch gear 21 is near rotor 11, each pawl 21d and 11d interlock become engagement state (engage meaning promptly, open).
On the other hand, shown in Fig. 2 (B), the 1st clutch member 4 is complied with the switching that divides to the tooth bottom from the crest part of the cam surface 41a of clutch control lever 41, clutch pinion 21 is moved upward because of the elastic force of compression ring spring 18, break away from from rotor 11, thereby the interlock between each pawl 21d and each the pawl 11d breaks away from, become the state (disconnect meaning promptly, close) of disconnection.
In addition, in Fig. 2 (A), be configured in the rotor 11 of below, by betiding itself and the brake moment of torsion that surrounds between its stator department 14 on every side, and before snap-action, be located in gyratory directions.That is, rotor 11 is because of the magnetize position of rotor magnet 11b, the location at gyratory directions when constituting this rotor 11 and stopping.Like this, when disconnecting energising, the 1st positioner that the brake moment of torsion that betides 14 of rotor 11 and stator departments positions when becoming rotor 11 interlocks that constitute the 1st clutch member.
On the other hand, when the interlock of the rotor 11 of rising breaks away from when clutch pinion 21 and above Fig. 2 (A), the holding section (omitting diagram) that is arranged on a side holding section on the clutch control lever 41 (omitting diagram) and formed the opposing party on clutch pinion 21 connects, thus, the revolution of clutch pinion 21 is prevented from, and locatees at gyratory directions.That is, the clutch pinion 21 that becomes the 2nd clutch member turns round with inertia force because of accepting the revolution of gear train 2 each parts as described later, but this revolution is obstructed because of the holding section that is arranged on the clutch control lever 41.In other words, under the state of the gyratory directions reinforcing of Xiang Suoding, the holding section of the holding section of clutch pinion 21 and clutch control lever 41 connects.
When continuing to clutch pinion 21 after energising is cut off and the interlock between the rotor 11, this location ends.And in case clutch pinion 21 and rotor 11 interlocks, then the engaging between the holding section of the holding section of clutch control lever 41 and clutch pinion 21 breaks away from and removes and locate.Like this, be arranged at and become the holding section on the clutch switching device shifter clutch control lever 41 and be arranged on the 2nd positioner that positions when holding section on the clutch pinion 21 that becomes the 2nd clutch member becomes clutch pinion 21 interlocks.
As mentioned above, clutch pinion 21 and rotor 11 are positioned when interlock.When both 11,21 interlocks, each claw 11d, the mutual front end of 21d does not contact, this is positioned at regular occlusal position makes each claw 11d, 21d interlock.Yet, because the various reasons of the tolerance of parts and assembling tolerance etc., sometimes 1, each claw 11d can take place, the front end of 21d (summit) always is in situation about contacting with each other.But this example is owing to constitute the structure of following explanation, therefore, even if produce above-mentioned situation, each claw 11d, the fore-end of 21d contacts, clutch pinion 21 and rotor 11 lockings; Perhaps, under the state that breaks away from from regular occlusal position, can prevent that claw from embedding each other mutually.
With 21 opposed of the clutch pinions of the rotor 11 that becomes the 1st clutch member, that is, and above, as mentioned above, formation can with 4 claw 11d of each claw 21d interlock of clutch pinion 21.And, the structure (consulting the symbol h among Fig. 3 (A)) of to be unique claw 11d2 than other near the direction of the claw 21d of right opposite the form some height gauge modest ability of 1 claw 11d1 among these 4 claw 11d.The fore-end (summit) of the claw 11d1 that this size is long is compared with the fore-end (summit) of the claw 11d2 of other size weak point, becomes sharply outstanding, but also can form some R, has fillet.
The setting of above-mentioned fillet be for: because of clutch pinion 21 pressing down by the convex surface 41a of clutch control lever 41, make clutch pinion 21 approaching, be sticked in rotor 11 when carrying out joint action, the fore-end butt of the fore-end of the claw 21d of clutch pinion 21 and this claw 11d1, at this moment, the claw 21d of clutch pinion 21 can withdraw to Fig. 2 below (rotor 11 sides).
On the one hand, the short claw 11d2 fore-end separately of height dimension forms the plane, and claw shape integral body becomes platform shape shape.So the nose angle part of the claw 11d2 that this size is short also forms R, has some fillets.This structure is connected to this claw 11d2 when going up when the fore-end of the claw 21d of clutch pinion 21, the claw 21d of clutch pinion 21 in Fig. 2 easily downwards (rotor 11 sides) withdraw from, claw 21d can be guided to correct occlusal position.
In addition, as shown in Figure 4, the occlusal position of said here regular (correctly) is meant that in the gyratory directions of rotor 11, each pawl 11d of rotor 11 enters the position near side in front of the claw 21d of clutch pinion 21.By entering this occlusal position, each claw 11d of rotor 11 turns round in the claw 21d that promotes clutch pinion 21, and clutch pinion 21 is passed in the revolution of rotor 11.
In addition, that clutch pinion 21 is pushed is close, be sticked in rotor 11, when carrying out joint action, at the fore-end (summit) of each claw 11d, 21d under state of contact each other, the power that clutch pinion 21 is accepted to press direction from clutch control lever 41, the claw 21d of clutch pinion 21 is with the claw 11d interlock of rotor 11 time, and the claw 11d1 that size is long becomes can prevent the parts that enter non-normal position, prevent to enter the position of departing from.
That is, like this fore-end of each claw 11d, 21d desire each other under the state of butt near the time, the phenomenon below in the gear motor of this example, producing.
Shown in Fig. 3 (A), 4 claw 21d of 4 claw 11d of rotor 11 sides and clutch pinion 21 sides are respectively during interlocks, at first the fore-end butt of the 21d of claw arbitrarily of claw 11d1 that original dimensions is long and clutch pinion 21 sides.The fore-end of the claw 11d1 that size is long, as mentioned above, owing to become slightly with the sharp keen leading section of fillet, therefore, the claw 21d of clutch pinion 21 sides that contacts with this part glides further mobile downwards.In addition, in this example, level and smooth for when the further contact be provided with fillet at the fore-end of claw 11d1, but this fillet is not good.
As mentioned above, in this example, its structure is, prior to contacting of other claws 11d2 and each claw 21d, only the claw 11d1 that size is long at first with one of the claw 21d of clutch pinion 21 sides butt.This contact becomes guiding, the claw 11d2 interlock that guides other claws 21d to lack with size on correct position respectively.
That is,, then become the state shown in Fig. 3 (B) in case further clutch pinion 21 is pushed towards the below from initial contact.Its result, the claw 21d decline of other of clutch pinion 21 connects with the claw 11d2 that the size of rotor 11 sides is lacked respectively.At this moment, as mentioned above, because the initial contact between the 21d of claw arbitrarily of the claw 11d1 of size length and clutch pinion 21 becomes guiding, therefore, the interlock of other claws is directed to regular occlusal position.In addition, the fore-end of the claw 11d2 that size is short, as mentioned above, owing to be platform shape shape, and its bight has fillet slightly, therefore, have the claw 21d of the clutch pinion 21 that the bight of fillet contacts to glide with this, further above-mentioned regular occlusal position downwards moves smoothly.Thus, claw 21d does regular interlock with the claw 11d2 that the size of rotor 11 sides is lacked respectively.That is, long size claw 11d1 becomes guiding in the interlock between the claw 21d arbitrarily of clutch pinion 21 sides, and the interlock between other each claw 21d of short claw 11d2 of other sizes and clutch pinion 21 sides is begun.
In addition, in this example, the claw 21d of the claw 11d of rotor 11 sides and clutch pinion 21 sides all respectively has 4, has the long claw 11d1 of size in rotor 11 sides, but claw 11d, the radical of 21d not only is defined in 4, even be less than or good more than 4.In addition, also can constitute different claw radicals in rotor 11 sides with clutch pinion 21 sides.Also can in clutch pinion 21 sides the long claw of size be set not in rotor 11 sides.
This gear motor because above-mentioned the 1st clutch member 4 is an engagement state, thereby transmits the actuating force of AC motor to output shaft 3, make sliding pinion 7 revolutions that are pressed into, are fastened on output shaft 3 front ends, and tension is by the control lever 8 of class with institute's constant load.And, by making the 1st clutch member 4 be off-state, therefore, disconnect the connection between rotor 11 and the output shaft 3, and with 41 lockings of relative rotor 11 independent clutch pinions 21 usefulness clutch control levers.Thus, stop each (with the rightabout meaning that promotes control lever 8) revolution of gear train 2, control lever 8 is promoted to position retentive control bar 8 behind institute's allocation in the other direction.And this state is the energising of the oriented AC motor 1 by keeping and keeping.In addition, by the energising that stops from this state to AC motor 1, the 2nd clutch member then described later also becomes off-state, and the confining force of its retentive control bar 8 is disengaged, and therefore, follows the load that is added in control lever 8 itself, gets back to the position before control lever 8 promotes.
Below, the relevant structure that realizes the gear motor action is described in detail in detail.
Bottom surface side in case body 12a disposes in order to make control lever 8 move, become the AC motor 1 of drive source.AC motor 1 has the stator department 14 that is disposed in the motor box 13 that forms cup-shaped, freely supports the armature spindle 15 of this rotor 11 in the rotor 11 that is disposed by subtend with respect to stator department in the interior week of this stator department, revolution.So armature spindle 15, one end run through the bottom surface of motor box 13, when connecting with the bottom surface of case body 12a, the other end is embedded in dead eye 12e on the box cover 12b is given prominence to, is formed in the top of AC motor 1.
Below the induction revolving body that uses Fig. 5 and Fig. 6 just to be configured in rotor 11 and rotor 11 inboards describes.
As shown in Figure 5, rotor 11 comprises: be provided with the 11a of pivoting support portion that runs through armature spindle 15 (with reference to Fig. 1) hole, the outstanding big slightly rotor magnet 11b of ring-type above the outer circumferential side engaging of the 11a of this pivoting support portion has its upper lateral.In addition, in this example, on the face of interior all spatial portion one side sides of this rotor magnet 11b, embedded and the rotating ringshaped magnet 11c of rotor 11 interlocks.Thus, constitute one, constitute rotor 11 with the rotor magnet 11b of stator department subtend configuration, the ringshaped magnet 11c that the 16 rotating magnetic induction of induction revolving body is used with magnetic induction.
Inboard again at ringshaped magnet 11c can turn round and freely dispose with the non magnetic conducting ring 16a of this ringshaped magnet 11c subtend configuration and back side support 16b has been installed and has had the induction revolving body 16 of pinion part 16d.In addition, in case this induction revolving body 16 because the revolution ringshaped magnet 11c revolution of rotor 11, because of magnetic induction, makes non magnetic conducting ring cater to the revolution of this ringshaped magnet 11c and turns round.By this, this induction revolving body 16 caters to rotor 11 as one integral body and turns round.In addition, ringshaped magnet 11c and non magnetic conducting ring 16a become the drive source portion that makes 5 actions of following clutch operating mechanism, the pinion part 16d of induction revolving body 16 and following sector gear interlock.About the structure of induction revolving body 16, the back is described in detail.
As shown in Figure 5, in interior all side parts of the 11a of pivoting support portion of rotor 11, form groove 11f.In this groove 11f, embedded to making rotor 11 and clutch pinion 21 break away from the compression ring spring 18 of interlock.
In addition, as shown in Figure 6, in the axial end of the rotor magnet 11b of rotor 11, at circumferential impartial 4 recess 11k of place that are provided with.During the reverse revolution of rotor 11 beginning, the protruding 25c that is formed on the sector gear 25 in order to stop this reverse revolution is embedded among these recesses 11k (with reference to Fig. 7) during starting.Structure thus, in case rotor 11 reverse revolutions are followed the induction revolving body 16 of rotor 11 and done the contrary revolution opposite with regular direction, when sector gear 25 courts turned round in the opposite direction with regular side, protruding 25c was embedded in the recess 11k.Thus, rotor 11 is a blocking temporarily, and the reaction during thereafter owing to conflict is transformed into the forward revolution.
Be configured in the non magnetic conducting ring 16a of induction revolving body 16 most peripherals of this spline structure, be configured in the radial direction inboard that is installed on the ringshaped magnet 11c on the above-mentioned rotor 11 by subtend.Non magnetic conducting ring 16a becomes and follows the rotating member of ringshaped magnet 11c as mentioned above, by non magnetic inductive means non magnetic and that have conductivity, specifically, is made of the member that metals such as copper and aluminium form.
Thus, make the driven rotating magnetic strength stress of non magnetic conducting ring 16a at ringshaped magnet 11c, the induction revolving body 16 that non magnetic conducting ring 16a is fixed on outer peripheral face is followed the revolution of rotor 11, turns round in the same way with rotor 11.That is, above-mentioned ringshaped magnet 11c and inductance loop 16a become because of magnetic induction, and make induction revolving body 16 relative rotors 11 make driven rotating magnetic induction slewing equipment, and responding to revolving body 16 becomes because of magnetic induction and be driven in rotor 11 rotating revolving bodies.
Secondly, use Fig. 1 and Fig. 7, just the actuating force of AC motor 1 is passed to the gear train 2 of output shaft 3 and the clutch operating mechanism 5 that the 2nd clutch member that is disposed in this gear train 2 is switched, do an explanation.
Below, be described in further detail the relevant each several part that constitutes gear train 2.In the time of as the 1st layer of gear of gear train 2, constitute the clutch pinion 21 of the 1st a clutch member part, as mentioned above, with rotor 11 arranged coaxial.That is, clutch pinion 21 rotatable moving about freely are embedded on the armature spindle 15, and the upper surface subtend with rotor 11 below it disposes.And clutch pinion 21 is clamped compression ring spring 18 and is put on rotor 11, because of the spring power of compression ring spring 18, and by the top reinforcing in Fig. 1.
The upper part of this clutch pinion 21 face formation to the joint of the 1st clutch member 4, disconnect the cam surface 41a of the clutch control lever 41 of the clutch switching device shifter that switches.Therefore, clutch pinion 21 often is urged on cam surface 41a because of the elastic force of compression ring spring 18.This cam surface 41a is constituted with the part that becomes paddy portion by depressing the 41c of portion.Clutch control lever 41, the one end is rotatable freely to be bearing on the axle that supports travelling gear 23; The other end of clutch control lever 41, a side that promptly has cam surface 41a has slotted hole 41b (with reference to Fig. 7), has embedded armature spindle 15 in this slotted hole 41b, and its formation is only swung it in deciding scope.
Have, clutch control lever 41 has the operation that enters in the clutch control lever operating groove 3b that is formed at the 3a of output shaft gear portion opposed faces side with projection 41e (consulting Fig. 1) again.Therefore, in case the turning power of rotor 11 is passed to the 3a of output gear portion, or because of load makes output shaft 3 to any direction revolution, operation is conducted in the clutch operating ditch 3b with projection 41e, and clutch control lever 41 rotates thus.Promptly, clutch control lever 41 moves with the revolution interlock of gear train 2, and the rotational angle of corresponding output shaft 3 switches jag part and the paddy portion of above-mentioned cam surface 41a, thus, constitute the structure that change action is carried out in the joint and the disconnection of the 1st clutch member 4.
Depress the 41c of portion by the A-stage that does not constitute energising to form energising, with control lever 8 be pulled up to institute's allocation during, clutch pinion 21 is depressed to rotor 11 sides.Thus, the claw 11d interlock mutually of the claw 21d of clutch pinion 21 and rotor 11, rotor 11 and clutch pinion 21 unitary rotation.That is, the 1st clutch member 4 becomes engagement state.
And, in case the 3a of output gear portion finish fixed revolution because the guiding of clutch control lever operation ditch 3b is rotated clutch control lever 41, switch jag part and the paddy portion of cam surface 41a.Thus, clutch 21 is shifted to the top because of the spring power of compression ring spring 18.Before mobile end fully upward, clutch pinion 21 is in the rotating while, and the holding section (omitting diagram) on the clutch control lever 41 following institute allocations that make the holding section (omitting diagram) that forms in the above and be formed at swing connects.Thus, clutch pinion 21 is stuck the location at gyratory directions.Behind this location, clutch pinion 21 further is moved upward because of the elastic force of compression ring spring 18.For this reason, clutch pinion 21 is under the state that is located in institute's allocation on the gyratory directions, and disengagement is connected with rotor 11.That is, the 1st clutch member 4 switches to off-state.
For this reason, each gear that constitutes gear train 2 is controlled the load forces of bar 8, will turn round round about.But, as mentioned above because clutch pinion 21 is fixed under the state of gyratory directions being positioned because of clutch control lever 41, with the sun gear 32 of the planetary gear 22 of clutch 21 interlocks by locking.Further, add this state, for keep "on" position because of magnetic strength stress ring gear 33 also by locking.Its result, each gear of gear train 2 is not done reverse revolution by locking even be controlled the load forces of bar 8 yet.
In addition, disconnected the energising to AC motor 1, lost the induction force to induction revolving body 16, because of the elastic force of spring member 39, sector gear 25 has been replied, the engaging between the revolution limited section 26 of clutch gear 27 and sector gear 25 breaks away from.Thus, clutch gear 27 becomes freedom, its as a result the ring gear 33 of planetary gear 22 also become freedom.Thus, each gear that constitutes gear train 2 because of the load forces of control lever 8 to the direction of pulling out control lever 8, i.e. the revolution of rightabout when CD-ROM drive motor.In contrary turning course, follow the contrary revolution of the 3a of output gear portion of gear train 2, above-mentioned clutch control lever 41 rotates the position side of control lever 8 before pulling on.Thus, the jag part of the cam surface 41a of clutch control lever 41 and paddy portion are switched.
Its result, the 41c of the portion that depresses of clutch control lever 41 with clutch pinion 21 under rotor 11 side pressures.Thus, the claw 11d interlock of the claw 21d of clutch pinion 21 and rotor 11.Clutch pinion 21 is positioned at gyratory directions as mentioned above.On the one hand, rotor 11 is positioned at gyratory directions by the brake moment of torsion in this rotor 11 and 14 generations of stator department as mentioned above.
The location of the location of clutch pinion 21 and rotor 11 is to consider to make each member opposed claw 21d separately, and 11d interlock smoothly sets.That is, each claw 21d, the fore-end of 11d each other under the butt state, clutch pinion 21 be pressed into rotor 11 sides, locking both 21,11, constitute both location of 21,11.
Yet, because of the accumulation of each component tolerance and assembling tolerance etc., can infer each claw 21d, the situation of butt during the mutual interlock of the fore-end of 11d.At this moment, in clutch pinion 21 and rotor 11 lockings, also can expect sometimes as mentioned above from breaking away from the situation that regular position is embedded into.For this reason, in this example, as mentioned above, constitute 1 claw 11d of rotor 11 sides with the claw 11d1 of long size, even the front end butt of claw 21d and claw 11d during interlock, each claw 21d of clutch pinion 21 is imported regular occlusal position, and the following embedding of state, clutch pinion 21 and the rotor 11 that are formed on disengaging can lockings.
Like this, in case clutch pinion 21 is depressed to rotor 11 sides, the claw 21d of clutch pinion 21 and the claw 11d of rotor 11 are in regular position interlock, and the 1st clutch member becomes engagement state.Again, after claw 11d, the 21d interlock, come from clutch control lever 41, the engaging of the location of clutch pinion 21 is disengaged.And disconnect energising this moment, because above-mentioned the 2nd clutch member is an off-state, control lever 8 can move the position before being pulled away from.
Again, the planetary gears 22 that becomes the 2nd clutch member is made of following parts: have and clutch pinion 21 interlocks, acceptance is accepted gear 32b and actuating force is passed to the sun gear 32 of the travelling gear 32a of planetary gear 36 from the actuating force of rotor 11 sides, the gear 33 of periphery gear part 33b of speed increasing gear 28 with terminal part of all gear part 33a and clutch operating mechanism 5 in the interlock that is snapped at planetary gear 36, have the support plate 34a that can turn round planetary gear bearing 36 freely respectively and with the planetary gear supporting gear 34 of the pinion part 34b of travelling gear 23 interlocks.
For this reason, by the action that engages, stops each parts of clutch operating mechanism 5 between revolution limited section 26 that makes sector gear 25 and the clutch gear 27, in case prevent the revolution of the ring gear 33 that is snapped at speed increasing gear 28, be engagement state between sun gear 32 and the planetary gear supporting gear 34 then, be passed to the turning power of the rotor 11 of sun gear 32 by clutch pinion 21, by the travelling gear 23 that is snapped at planetary gear supporting gear 34, reached the 3a of output gear portion, make output shaft 3 with sliding pinion 7 revolutions.Its result has control lever 8 with the balladeur train of sliding pinion 7 interlocks (omitting diagram) and overcomes the load that is added in control lever 8 itself, is pulled on by the actuating force of AC motor 1.
On the other hand, clutch operating mechanism 5 becomes the member that the 2nd clutch member that is configured in the above-mentioned gear train is engaged, disconnects.Promptly, clutch operating mechanism 5 is documented in half as the left side of launching cutaway view Fig. 1, constitute by following member: because of the sensed rotating induction revolving body 16 of above-mentioned ringshaped magnet 11c, with 16 interlocks of induction revolving body, become the sector gear 25 of the revolving member that is subjected to the elastic force of spring member 39 on the direction that engages that breaks away from clutch gear 27 simultaneously, have on its outer peripheral face can shirk freely be formed at sector gear 25 on the clutch gear 27 of the engaging protrusion 27a that engages of revolution limited section 26, in the time of with the small-diameter gear 27b interlock of this clutch gear 27, speed increasing gear 28 with ring gear 33 interlocks of planetary gears 22.
Like this, make when being engagement state between sun gear 32 and the planetary gear supporting gear 34, the above-mentioned the 1st clutch apparatus 4 also becomes engagement state.At this moment, the revolution of rotor 11 is reached output shaft 3 sides by the sun gear 32 and the planetary gear 34 of planetary gears 22.Thus, when control lever 8 promoted action, above-mentioned clutch control lever 41 rotated with this action interlock.After finishing to promote action, only have the 1st clutch member 4 to be off-state, and the 2nd clutch member is kept engagement state.Therefore, each gear of the clutch operating mechanism 5 that is made of magnetic strength stress is kept by the state of locking.Its result as mentioned above, rotates for this reason, and as mentioned above, control lever 8 is stuck close in the position of rolling.
And, from the further energising that disconnects to AC motor 1 of this state, in case the magnetic strength stress between rotor 11 and the induction revolving body 16 almost disappears, sector gear 25 is because of the spring force of spring member 39, rotate in the opposite direction to side, the engaging between revolution limited section 26 and the clutch gear 27 is broken away from explanation just now.Thereby, the blocking of each one of releasing clutch operating mechanism 5.For this reason, ring gear 33 and planetary gear supporting gear 34 are off-state, want the turning power and gear train 2 retrograde transmission of reverse rotating output shaft 3 because of external load, be transmitted by planetary gears 22 and speed increasing gear 28 and clutch gear 27, clutch gear 27 becomes backlash and changes.Its result, although sun gear 32 sides by locking, the fastening state of control lever 8 is disengaged.
Below further describe each one that constitutes clutch operating mechanism 5.
At the fulcrum 25a with sector gear 25 is the center, to the opposition side on 1 fan-shaped limit extend, the fore-end of the 25b of the portion of granting of rotatory force, engaging has the one end to be stuck close in to establish the other end of the spring member 39 on the pin 38 that is arranged on motor box 13.Sector gear 25 is subjected to drawing with just turning round of AC motor 1 rotatory force of reverse (arrow indication A direction among Fig. 7) rotation of rotation because of the elastic force of spring member 39.
As mentioned above, in case disconnect energising to AC motor 1, engaging between revolution limited section 26 and the clutch gear 27 breaks away from because of the elastic force of spring member 39, at this moment, the revolution of clutch pinion 21, the revolution of the sun gear 32 of prevention and clutch pinion 21 interlocks are thus still continued to stop in the holding section of above-mentioned clutch control lever 41 (omission diagram).But, because the fastening state between revolution limited section 26 and the clutch pinion 27 is disengaged, thus, even if the revolution of sun gear 32 is prevented from, the turning power that is caused by the load forces of control lever 8 is reached speed increasing gear 28 sides by planetary gears 22, makes clutch gear 27 idle running.Its result, control lever 8 is drawn towards the outside of case, and each gear that constitutes gear train 2 is done reverse revolution thereupon.
Above-mentioned example is the example of only example of the present invention, and still, the present invention is not limited to this, in the scope that does not exceed aim of the present invention, can take all distortion to implement.For example, in above-mentioned example, with the clutch control lever operating groove 3b that forms on output gear 3a is guiding, make clutch control lever 41 actions that the 1st clutch member 4 engaged, disconnect the clutch switching device shifter of switching, but this ways is not particularly limited to be set on the output gear 3a.That is, can be with on other the gear in the reducing gear train that is arranged on for the member that makes clutch switching device shifter action between rotor 11 and the output shaft 3.
In addition, in above-mentioned each example, the 1st clutch member that constitutes the 1st clutch member 4 as rotor 11 itself, but also can be made of other the member with rotor 11 interlocks.Further, in above-mentioned each example, each is self-align to utilize 2 clutch member brake moments of torsion and clutch control lever 41, when preventing two clutch member lockings, by have long size claw 11d1 in rotor 11 sides, formation prevents that two clutch members are in the chimeric structure in position that breaks away from regular position.But these 2 kinds of methods can independently be proved effective respectively, therefore, also can only utilize wherein a kind of method.
Adopt a kind of method in back, that is, adopt to have the method for the claw 11d1 of long size, then can prevent the locking that the butt because of the fore-end of claw 11d, 21d causes, and prevent embedding both sides under regular position disengaged position in rotor 11 sides.But, by carrying out above-mentioned location, can not utilize the revolution of rotor 11, directly make claw 21d to moving with the position of the regular interlock of claw 11d.
In addition, in above-mentioned each example, be to adopt between rotor 11,51 and output shaft 3, to have 2 clutch apparatus, draw high the load parts control lever 8 the 1st the action, remain in draw high the position the 2nd the action, and be back to the gear motor of the 3rd on initial position action from above-mentioned state, but clutch apparatus is only established one and also can.
Again, in above-mentioned each example, structure makes passes to control lever 8 with the revolution that is connected the sliding pinion 7 of output shaft 3, make control lever 8 have the level and smooth structure that moves, but also can be on output shaft 3 directly connect the control lever member, form other the formation such as structure of stretching steel wire by this control lever member is rotated.
As mentioned above, according to the present invention, in order to prevent the mutual locking that contacts two clutch members that cause in summit because of the claw of joint and cut-off clutch device, utilize the brake moment of torsion to make the claw location of the 1st clutch member side, utilize the clutch switching device shifter to make the claw location of the 2nd clutch member side.For this reason, the locking of two clutch members that cause because of the butt of claw fore-end can be carried out the joint and the disconnection of clutch apparatus reliably.
In addition, according to other the present invention, being provided with 1 initial claw with other long size claw of interlock mutually in any one party of two clutch members, is guiding with the interlock of this length size claw, and the claw that other sizes can be lacked guides to regular occlusal position.For this reason, the revolution that can obtain making rotor is reliably to the clutch member of output shaft side transmission, and its result can carry out the joint and the disconnection of clutch apparatus reliably.
