First gear 42 is engaged in the first rotor gear 41.There is the first helical teeth portion 422 of driving side teeth portion 421 and minor diameter more relative to this driving side teeth portion 421.First helical teeth portion 422 is the parts being formed as " helical teeth " as mentioned above.The driving side teeth portion 421 of the first gear 42 engages with the first rotor gear 41.Therefore, the first gear 42 rotates along with the rotation of the first rotor gear 41.
Second gear 44 is engaged in the first gear 42.Second gear 44 has: the second helical teeth portion 441 that diameter is relatively large; And the slave end teeth portion 442 that diameter is relatively little.Second gear 44 is supported as can rotating freely and can moving in the axial direction by the second gear support axle 86.As mentioned above, the second helical teeth portion 441 is the parts being formed as " helical teeth ".Slave end teeth portion 442 is so-called worm gear part that the worm screw portion 51 had with load applying mechanism 50 engages.In addition, slave end teeth portion 442 both can be helical teeth also can be spur wheel.
Second helical teeth portion 441 of the second gear 44 engages with the first helical teeth portion 422 of the first gear 42.Therefore, the second gear 44 rotates along with the rotation of the first gear 42.When syncmotor 10 rotates forward, because being applied and the rightabout load of its sense of rotation the second gear 44 by load applying mechanism 50, thus produce thrust downward in the axial direction.Therefore, when the first gear 42 rotates, the second gear 44 rotates and moves down in the axial direction.
Locking pole 45 is flat parts, is configured at the downside of the second gear 44.Specifically, under the state of movement in the axial direction, can supported by the second gear support axle 86 identically with the second gear 44.Locking pole 45 is formed recess 452, and this recess 452 is sticked in the not shown protuberance formed in the axial direction in the inner side of the sidewall of lower shell body 82.By the engaging of described protuberance with recess 452, locking pole 45 rotate be prevented from while supported as can the state of movement in the axial direction by the second gear support axle 86.Be formed with locking part 451 at a side end of locking pole 45, this locking part 451 is formed as thicker than other parts.Be configured with in the downside of locking pole 45 upwards to the force application part 46 (helical spring) that locking pole 45 exerts a force.By this force application part 46, generally (when syncmotor 10 does not drive), locking pole 45 is positioned at the position top by locking part 471 than sealed gear 47.Further, because be configured with the second gear 44 in the upside of locking pole 45, therefore the second gear 44 is also by the state upwards exerted a force in the axial direction.It is little to the thrust downward in the axial direction of the second gear 44 generation when the active force of force application part 46 rotates along with the rotation of the first gear 42 than the second gear 44.Namely, when the second gear 44 rotates, the second gear 44 overcomes the active force of force application part 46 and moves down in the axial direction.When the second gear 44 moves down in the axial direction, the locking pole 45 be positioned on the downside of it also moves down.The locking part 451 of the locking pole 45 moved down is positioned at the height roughly the same by locking part 471 with sealed gear 47.
Sealed gear 47 has: by locking part 471; And be positioned at and be formed with this by the sealed teeth portion 472 on the flat board of locking part 471.Formed in the mode outwardly of the flat board from circle by locking part 471.When locking pole 45 moves down, due to locking part 451 and sealed gear 47 relative and put by locking part 471 of locking pole 45, therefore the precalculated position (position that locking part 451 abuts with by locking part 471) that is rotated in of sealed gear 47 is prevented from.On the other hand, sealed teeth portion 472 engages with the outer toothed portion 311 of the fixed gear 31 forming clutch mechanism.Therefore, when the rotation of sealed gear 47 is prevented from, the rotation of the fixed gear 31 engaged with it is also prevented from.In addition, in the present embodiment, sealed gear 47 has the braking part 473 as cenrifugal brake.Braking part 473 applies load to the direction hindering sealed gear 47 to rotate, thus sealed gear 47 is not rotated with too high speed.The effect of described braking part 473 is described after a while.
The worm screw portion 51 extended along the direction orthogonal with the axial direction of the second gear 44 engages with slave end teeth portion 442 (worm gear part).Worm screw portion 51 is strip, and slave end teeth portion 442 and worm screw portion 51 form accelerating gear mechanism (worm screw portion 51 rotates a circle when slave end teeth portion 442 rotates the distance of a tooth).Therefore, the rotation of the second gear 44 is accelerated and passes to worm screw portion 51.
(other structure)
As shown in Fig. 1, Fig. 8, compound gear 24 is configured with fan-shaped bar 60.Fan-shaped bar 60 is by with by compound gear 24, the axle supported as rotating freely is that the axle of same axle supports as rotating freely.Engaging protrusion 61 is formed at the lower surface of fan-shaped bar 60.Described engaging protrusion 61 is sticked in the cam path 252 of the upper surface being formed at cam wheel 25.Further, this fan-shaped bar 60 is also formed with the sealed projection 62 of input side gear and tilting cam 63.Omit the detailed description to described engaging protrusion 61, cam path 252, the sealed projection 62 of input side gear and tilting cam 63, but the function of each parts is as follows.When cam wheel 25 rotates to the direction rolling wire rod 27, by the engaging protrusion 61 being sticked in cam path 252, fan-shaped bar 60 is rotated to input side gear 22 side.When fan-shaped bar 60 moves to precalculated position (wire rod 27 is rolls-up onto precalculated position), in order to stop the retracting of wire rod 27, the sealed projection of input side gear 62 act on input side gear 22 by sealed projection 223, thus stop the rotation of input side gear 22.Meanwhile, be released by the second exteranl gear 21 that tilting cam 63 presses downwards in the axial direction, and moved up in the axial direction (the second exteranl gear 21 is positioned at the second place) (with reference to Fig. 4) by helical spring 28.Thus, the upper engagement portion 212 of the second exteranl gear 21 is removed with the engaging of the lower engagement portion 412 of the first rotor gear 41.Namely, in syncmotor, the power of 10 is not passed to the state of the second exteranl gear 21.
(action of motor unit)
Below the general action of the motor unit 1 with above structure is described in detail.In the following description, respectively to one) transmission of power action and two) power cut action is described, wherein, one) transmission of power action by the transmission of power of syncmotor 10 to the driven member 90, two being positioned at original position) power cut action cut off syncmotor 10 power transmission and make driven member 90 return-to-home position.
One) transmission of power action
When the state (power that wire rod 27 is not rolls-up onto state, the i.e. syncmotor 10 of belt wheel 26 does not act on the state of driven member 90) being positioned at original position from driven member 90 drives syncmotor 10 (making syncmotor 10 rotate forward) to side, the second exteranl gear 21 and the first rotor gear 41 rotate.At this moment, when syncmotor 10 reverses, not shown reversal prevention mechanism action, even if thirty years of age syncmotor 10 rotates forward.When syncmotor 10 drives, due to the rotation of the first rotor gear 41, thus first gear 42 with the driving side teeth portion 421 engaged with this first rotor gear 41 rotates.
When the first gear 42 rotates, second gear 44 with the second helical teeth portion 441 of engaging with the first helical teeth portion 422 of the first gear 42 rotates.The slave end teeth portion 442 (worm gear part) of this second gear 44 engages with the worm screw portion 51 of load applying mechanism 50, thus due to the rotation of the second gear 44, the load portion 52 of load applying mechanism 50 also rotates.Rotate in load portion 52, and when its speed becomes large, the direction stopped produces load (torque) making rotation.Described load is delivered to second gear 44 with slave end teeth portion 442 and the first gear 42 being engaged in the second gear 44 from worm screw portion 51.Thus, the first gear 42 and the second gear 44 are subject to the load contrary with its sense of rotation.
As mentioned above, the transmission of power between the first gear 42 with the second gear 44 is engaged by " helical teeth " and is realized.Therefore, the second gear 44 received from the load opposite to the direction of rotation of load applying mechanism 50 is subject to thrust downward in the axial direction because of the rotation of the first gear 42.Namely, the second gear 44 is by the engagement of " helical teeth " and load opposite to the direction of rotation and rotation edge, limit axial direction moves down.
Further, in the present embodiment, because the second gear 44 is also realized by " helical teeth " with engaging of load applying mechanism 50, therefore larger thrust downward is in the axial direction produced to the second gear 44.Namely, the load produced by load portion 52 is delivered to the second gear 44 by worm screw portion 51 with engaging of slave end teeth portion 442, therefore also produces to the second gear 44 thrust downward in the axial direction produced by the transmission of this load.
When the second gear 44 moves down in the axial direction, the locking pole 45 be configured on the downside of it overcomes the active force of force application part 46 and moves down in the axial direction.When so depressing locking pole 45, the locking part 451 being arranged at locking pole 45, at the height roughly the same by locking part 471 with sealed gear 47, is positioned at the position opposed in the circumferential with sealed gear 47.Therefore, in this condition, the rotation of sealed gear 47 is stoped by the locking part 451 of locking pole 45.Namely, in the state that the rotation of sealed gear 47 is prevented from.
The sealed teeth portion 472 of sealed gear 47 is engaged in the outer toothed portion 311 of fixed gear 31, and fixed gear 31 forms the planetary gear set of clutch mechanism.Therefore, when the rotation of sealed gear 47 is prevented from, the rotation of fixed gear 31 is also prevented from.Thus, make the transmission from the power of the first transmission group be " connection " state by clutch mechanism, and the power in syncmotor 10 can be delivered to the state of driven member 90 by the first transmission group.Thus, the second gear 44 by moving down along its axial direction, and makes the transmission from the power of the first transmission group be " connection " state via clutch mechanism.
On the other hand, the second exteranl gear 21 rotated together with the first rotor gear 41 by the driving of syncmotor 10 is engaged with the major diameter teeth portion 221 of the input side gear 22 forming planetary gear set.Therefore, input side gear 22 rotates along with the rotation of the second exteranl gear 21.
Three planetary pinions 231 forming outlet side gear 23 are engaged in the outside of the minor diameter teeth portion 222 of input side gear 22.The interior teeth portion 312 of fixed gear 31 is engaged in the outside of the planetary pinion 231 arranged at equal intervals in the circumferential.As mentioned above, fixed gear 31 is in rotating the state stoped by sealed gear 47.Therefore, when input side gear 22 rotates, planetary pinion 231 revolves round the sun around the minor diameter teeth portion 222 of input side gear 22.When planetary pinion 231 revolves round the sun, the planet supporting gear 232 of planetary gear bearing 231 rotates.Namely, the rotating power of input side gear 22 is all passed to outlet side gear 23.
In addition, assuming that when the state that the rotation not being in fixed gear 31 is prevented from, if input side gear 22 rotates, then by planetary pinion 231, fixed gear 31 is dallied.Because there is the load of transmission group self after the planet supporting gear 232 in transmission of power group and put on the load of driven member 90, the rotating power of input side gear 22 is caused all to be delivered to fixed gear 31 side.So, in the present embodiment, the differential gear train by make use of planetary gear set switches " connection " state and " cut-out " state based on the first transmission group of clutch mechanism.
The major diameter teeth portion 242 of compound gear 24 is engaged in the gear part 2321 of planet supporting gear 232.Therefore, compound gear 24 rotates along with the rotation of planet supporting gear 232.
The gear part 251 of cam wheel 25 is engaged in the minor diameter teeth portion 241 of compound gear 24.Therefore, cam wheel 25 rotates along with the rotation of compound gear 24.
When cam wheel 25 rotates, the belt wheel 26 being fixed on cam wheel 25 upper end rotates.When belt wheel 26 rotates, the wire rod 27 being fixed on belt wheel 26 is rolled by along wire rod groove 261.Owing to being fixed with driven member 90 at the end of wire rod 27, therefore driven member 90 is with the mode action rolled by wire rod 27.Such as, when the spool of driven member 90 as the drain opening of switch washing machine, by making spool be rolled by wire rod 27, opening drain opening and starting draining.
So, the rotating power of syncmotor 10 is passed to driven member 90 by the first transmission group.First transmission group is " connection " state by clutch mechanism, and a part for the rotating power of syncmotor 10 is also used as making the power of this clutch mechanism in " connection " state.
In addition, the rolling of wire rod 27 of being undertaken by belt wheel 26 is stopped as following explanation.When cam wheel 25 rotates to precalculated position (during wire rod 27 rolled-up prearranging quatity), the fan-shaped bar 60 with the engaging protrusion 61 engaged with cam path 252 rotates to input side gear 22 side.When fan-shaped bar 60 so rotates, the sealed projection of input side gear 62 that fan-shaped bar 60 has from circumference be connected to input side gear 22 by sealed projection 223.Thus, the state that the rotation of 22 is prevented from input side gear.Further, be released by the second exteranl gear 21 that the tilting cam 63 of fan-shaped bar 60 presses downwards in the axial direction, and move up (the second exteranl gear 21 is positioned at the second place) in the axial direction by helical spring.Thus, the upper engagement portion 212 of the second exteranl gear 21 is removed with the engaging of the lower engagement portion 412 of the first rotor gear 41, thus the power in syncmotor 10 is not passed to the state of the second exteranl gear 21.When the rotation of input side gear 22 stops, the action forming each parts of the first transmission group also stops.Namely, the wire rod 27 undertaken by belt wheel 26 roll stopping, in the state (when the spool of driven member 90 as the drain opening of switch washing machine, the state in maintaining drain opening and opening) keeping belt wheel 26 at this winding position.So, under the state that maintenance drain opening is opened, although syncmotor 10 continues to drive, the state of the second exteranl gear 21 (the first transmission group) is not delivered in its power.Therefore, the load putting on syncmotor 10 diminishes, thus can reduce power consumption.
So, by the transmission of power of syncmotor 10 to the transmission of power release of driven member 90.
Two) power cut action
When making driven member 90 return-to-home position from above-mentioned transmission of power release state, stop the driving (stopping being energized to syncmotor 10) of syncmotor 10.So because the rotation of the first rotor gear 41, first gear 42 stops, therefore the rotation of the second gear 44 also stops.When the rotation of the second gear 44 stops, the thrust disappearance downward in the axial direction to the second gear 44 produced because of the engagement of " helical teeth " and the load of load applying mechanism 50 applying.Because the second gear 44 is all biased parts 46 with the locking pole 45 be configured under it and upwards exerts a force in the axial direction, so when this thrust disappears, the second rotation edge, gear 44 limit axial direction moves up, and return-to-home position.Certainly, locking pole 45 also moves to this direction, and return-to-home position.In addition, make the power of the second gear 44 return-to-home position less due to what applied by force application part 46, so the rotating speed in the second gear 44 and load portion 52 is low, thus the counterweight in load portion 52 does not contact cylinder 531.Therefore, the payload being acted on the second gear 44 by load applying mechanism 50 does not increase, the second gear 44 return-to-home position glibly.
When locking pole 45 is moved up by force application part 46, it is high by the position of the short transverse of locking part 471 that the position of the short transverse of the locking part 451 of locking pole 45 becomes than sealed gear 47.Specifically, locking part 451 be positioned at the position do not overlapped in the circumferential by locking part 471.Therefore, the state that the rotation removing sealed gear 47 is prevented from, and the state that can rotate freely in sealed gear 47.Namely, the state that the fixed gear 31 of (planetary gear set) can rotate freely in clutch mechanism, namely in clutch mechanism be " cut-out " state.So, the second gear 44, by moving up along its axial direction, makes the transmission of power of being undertaken by the first transmission group in " cut-out " state via clutch mechanism.
Driven member 90 is by acting on the external load always wish return-to-home position of self.Such as, driven member 90 is spools of the drain opening of switch washing machine, makes spool to when opening the direction action of drain opening in the driving by motor unit 1, and spool is always to the direction force of closing drain opening.Therefore, when state, the i.e. clutch mechanism that can rotate freely in fixed gear 31 are for " cut-out " state, the load putting on driven member 90 is delivered to outlet side gear 23 (planet supporting gear 232) to make the mode of the first transmission group inverted running.Because clutch mechanism is in " cut-outs " state, therefore, so transmission and energy that the load that puts on driven member 90 produces is output (consumption) because of the idle running of outlet side gear 23.Thus, driven member 90 return-to-home position.
Further, when cam wheel 25 return-to-home position, the fan-shaped bar 60 with the engaging protrusion 61 engaged with cam path 252 rotates to the direction near cam wheel 25.When fan-shaped bar 60 so rotates, the sealed projection of input side gear 62 that fan-shaped bar 60 has is separated by sealed projection 223 with input side gear 22.Thus, in the state of the rotation of permission input side gear 22.Further, be pressed against tilting cam 63 by the second exteranl gear 21 that helical spring upwards exerts a force in the axial direction, thus move down in the axial direction (the second exteranl gear 21 is positioned at primary importance).Thus, the upper engagement portion 212 of the second exteranl gear 21 engages with the lower engagement portion 412 of the first rotor gear 41, and in syncmotor, the power of 10 is also passed to the state of the second exteranl gear 21.
At this moment, braking part 473 pairs of driven members 90 of sealed gear 47 are braked for the action applying of return-to-home position, thus slow down the impact putting on the first transmission group.Therefore, it is possible to prevent the breakage of all parts, the i.e. power transmission member of formation first transmission group.Further, when driven member 90 return-to-home position, the Strike note (when the spool of driven member 90 as the drain opening of switch washing machine, the Strike note of the surrounding of described spool collision drain opening) of each collision can be reduced.
So, if stop syncmotor 10, then removed the sealed of the fixed gear 31 forming planetary gear set by the effect of force application part 46, clutch mechanism makes the first transmission group in " cut-out " state.Thus, driven member 90 return-to-home position.
Above, mode of execution of the present utility model has been described in detail, but the utility model is not limited to above-mentioned any mode of execution, various change can be carried out in the scope not departing from main idea of the present utility model.
