Description

Electric driving device

The present invention relates to make the electric driving device that produces action with the certain load of the drive force of motor.

In the past, drive at draining valve, electric driving device is used in aspects such as ventilating fan air door driving, at the motor rotor of this electric driving device with drive load and need possess between with output link: make action with solenoid, transmit, cut off the clutch of motor output, when accepting motor output, cut off the switching mechanism of motor power when making the driving load move to assigned position and remain on the device of assigned position with output link, for example need the lever (referring to the real fair 5-17536 communique of Japan Patent) that prevents that motor from reversing for driving to load with output link.

In addition, as on Japanese patent laid-open 2-159942 communique, disclosing, at motor rotor with drive load and possess between with output link to make to produce and move with electromagnet, transmit and cut off the planetary gear type clutch of motor output, when the driving load moves to assigned position with output link, and continue to make motor to switch on later on, yet the revolution of the rotor of prevention is arranged also, this driving load is remained on device on its assigned position with output link, and have the electric driving device that cuts off simultaneously to motor and electromagnet powered switch mechanism.

Above-mentioned these electric driving devices, generally also have and prevent that dust, water from entering inner housing from the outside, in addition, solenoid and cam switch mechanism are configured in the same space (real fair 5-17536), gear train and driving load are configured in the same space (spy opens flat 2-159942) with output link.

Yet, fair strictly according to the facts 5-17536 communique is recorded and narrated has the electric driving device that cuts off motor powered switch mechanism when the driving load of accepting motor output moves to assigned position with output link, because of electric noise takes place in the open and close of switching mechanism action, electric driving device becomes the reason of the machine generation misoperation of using this device.In addition,, and need carry out the position adjustment of open and close, manufacturability and reliability are degenerated because of needs are provided with special switching mechanism.In addition, because of number of components increases, become the main cause that cost is improved.And then the recirculated water that is used for draining valve driving etc. to use switch dangerous, easily become accident cause.

In addition, have when driving load and move to assigned position and continue to switch on to motor in the back with output link, yet stoping the rotor revolution, remain in the device (spy opens flat 2-159942) of feature on its assigned position with output link driving load, owing to continue energising to motor, excessive loads is added on the motor, makes the motor lost of life.When using the synchronous mode motor as above-mentioned motor, because of rotor will and prevent that all the lever of motor counter-rotating from contacting with the prevention revolving member, become in little stroke range forward and backward repeatedly, be limited to rotor snapping member etc. and can not pin rotating situation, in fact can not use synchronous motor.

In addition, in traditional electric driving device, owing to use alienable housing usually, it being engaged, be used for topped its internal mechanism, is that the scene is when making water at the water of draining valve etc., water will enter inside from the housing cutting part that engages, and often the generation action is bad.

In addition, in traditional electric driving device, because for more cataclysmal cam switch mechanism need be arranged because of user, product specification, be to be installed on the same space with output link and specification almost constant solenoid, gear train with driving load, be in the same housing, so just there is relative customer requirements, the problem that the adaptability during specifications vary degenerates.In addition, also there is the problem that only to try to assemble verification to gear train.

In addition, with in the output link, usually its section configuration is formed simple shapes such as rectangle at the driving load of the rack configurations of traditional electric driving device.But, as driving the load output link,, using the synthetic resin occasion owing to consider to need to form heavy wall from intensity, exist pore or contraction etc. to make the size instability during because of shaping.Therefore cut apart when sliding between housing when it is clipped in, make loosening the change greatly.

Therefore, the object of the invention is to provide can not need special switching mechanism, and does not also produce overladen electric driving device on motor.

In addition, the object of the invention also is to provide does not need special opening and mechanism, and does not produce overload on motor, can also not make water enter inner electric driving device from the cutting part of housing.

In addition, the object of the invention is again to provide and does not need special switching mechanism, and on motor, do not produce overload, can also adapt to the change of customer requirements, specification rapidly, and can only the electric driving device that carries out verification be installed the examination of Assembling gear group.

In addition, the further purpose of the present invention also is to provide and can prevents to take place when driving load slides with output link loosening electric driving device.

Below, the action of the electric driving device of above-mentioned formation is described.In addition, this electric driving device is described by the action of setting as being used for rinsing maching draining valve (not shown) switching occasion.

Draining valve is in when cutting out, as shown in Figure 4, drives load and be in the state farthest that stretches out from device with output link 15.Thus as shown in Figure 4 drive load with output link 15 above effectively F often work, make draining valve closed tightly.At this moment, first clutch is wanted the 6b of portion and becomes second clutch to want the motor pinion 7 of portion and the triadic relation of clutch operating member 8 to be shown in Fig. 7 (A).Be exactly that clutch operating member 8 separates with motor pinion 7, makes first clutch want 6b of portion and motor pinion 7 to be disengaged because solenoid 9 disconnects.

Then, open draining valve and switch on, make the 6 rotating whiles of rotor, switch on, make solenoid 9 to connect to electromagnet 9b to motor 5 when needs.So, shown in Fig. 7 (B), make clutch operating member 8 close to motor pinion 7, the middle pressing face 8c of its cam surface is contacted with motor pinion 7.Thereafter, shown in Fig. 7 (C), the pressing face 8c of clutch operating member 8 overcomes the elastic force of helical spring 18 motor pinion 7 is further pushed downwards, makes first clutch want the 6b of portion to engage with motor pinion 7.At this moment, the revolution of rotor 6 is slowed down successively reach motor pinion 7, first order gear 10, second level gear 11, third level gear 12, output gear 13 and output pinion 14.In view of the above, make with the driving load of output pinion 14 engagement and overcome the elastic force of not shown spring of the elastic force F of its not shown spring and pressing member 20 with output link 15 slowly in the access to plant.Therefore draining valve is slowly opened.In addition, shift to Fig. 7 (C) from Fig. 7 (A), connection because of solenoid 9, the instantaneous mobile and instantaneous of movable core 9a carries out, yet, at that time, make first clutch want the junction surface 6c of the 6b of portion and the coupling/decoupling 7a of motor pinion 7 to collide, connect even often produce solenoid 9, and the situation that movable core 9a also is failure to actuate.But if even owing in such occasion, must make the situation separately of colliding of both 6c, 7a in returning of rotor 6 circled, at least through rotor 6 revolution week ages, and become Fig. 7 (c) state, promptly clutch is in the state of combination.

Because when driving load with output link 15 slowly in the access to plant time, output gear 13 turns round along the clockwise direction among Fig. 3 (A), the cam projection 8i of clutch operating member 8 is slowly moved in the stria 13e of cam path 13d go.And, when cam projection 8i comes position shown in the middle double dot dash line of Fig. 3 (B), promptly make drive load and soon be inhaled in the device fully with output link 15 before, make the pushes protrusion 13h of output gear 13 begin to push the second arm 8j of clutch operating member 8.With this pushing 8 beginnings of clutch operating member are turned round along the counter clockwise direction among Fig. 3 (B).One advances, effect because of the elastic force and the inclined-plane 8d of helical spring 18, make clutch operating member 8 and then instantaneous in the counterclockwise direction revolution, the contact position that makes motor pinion 7 and clutch operating member 8 is from pressure surface 8c is instantaneous to bottom surfaces 8e in-migration through inclined-plane 8d down, makes motor pinion 7 and first clutch want the engaging instantaneous being disengaged of the 6b of portion and becomes Fig. 7 (D) state.At this moment, drive load, make the relation of output gear 13 and clutch operating member 8 become Fig. 3 (B) state with in the output link 15 complete accesss to plant.Utilize this instantaneous operation can prevent from slowly to throw off the unfavorable condition that produces, for example can prevent the wearing and tearing of coupling/decoupling 7a of the junction surface 6c of rotor 6 or motor pinion 7 or damaged etc. because of clutch.

And at state shown in Fig. 7 (D), solenoid 9 is still connected, yet, want the 6b of portion to separate with first clutch because of motor pinion 7, make the turning power of rotor 6 can not reach driving load output link 15.In addition, at that time, rotor 6 continues revolution.In addition, drive load with on the output link 15, move thereby make the driving load promptly close the draining valve direction to its origin-location with output link 15 because the elastic force F of spring often acts on.But, thereby make motor pinion 7 stop revolution owing to the prevention rotating part 8b of clutch operating member 8 engages with the projection 7c of motor pinion 7.Therefore, make by gear train therewith the drivings load that links to each other of motor pinion 7 be prevented from the mobile of output link 15, and be maintained at state shown in Figure 5.Its result remains on open mode with draining valve, and draining is continued.

Next, after finishing draining, action describes when closing draining valve.At first, solenoid 9 is disconnected.So clutch operating member 8 is separated with motor pinion 7.In view of the above, shown in Fig. 7 (E), the prevention rotating part 8b of clutch operating member 8 and the projection 7c of motor pinion 7 are disengaged, and motor pinion 7 can be turned round.Its result makes the driving load that links to each other with motor pinion 7 by gear train begin to the origin-location because of spring force with output link 15, promptly closes the draining valve direction and moves.This is driven load be passed to output pinion 14, output gear 13, third level gear 12, second level gear 11 and first order gear 10 successively to the reset movement of its original position with output link 15.At this moment, make the gear train that is connected to first order gear 10 from output gear 13 become the speed increasing gear group, first order gear 10 and be integral rotating rubber system speed regulator 16 along clockwise direction high speed rotary among Fig. 4 and Fig. 5 with first order gear 10.So, because of centrifugal force outwards moves, bring into play braking function with cylindrical wall 1c sliding contact by its arm 16a.Therefore, become to make and drive load and slowly carry out with the reseting movement to original position of output link 15.In addition, make when the energising of motor 5 makes solenoid 9 outages and interrupt, yet, also can not make interruption, and be used for the driving of other load.

In addition, turn round in the counterclockwise direction, the cam projection 8i of the clutch operating member 8 that is in Fig. 3 (B) state is entered in the stria 13e after inclined plane part 13g slowly moves in the thick groove 13f of cam path 13d by making the gear 13 of having failed among Fig. 3 (B).Based on this action, make clutch operating member 8 along clockwise direction revolution among Fig. 3 (B), the relation that makes motor pinion 7 and clutch operating member 8 is promptly shown in Fig. 7 (A).

And then, proceed to when being about to arrive origin-location (Fig. 4 state) when driving the reset movement of load with output link 15, pressing member 20 and the inclined plane shape 15b of portion that is pressed contacts, and push the driving load with output link 15 with not shown spring force, will drive load firmly and putting with output link 15 manual reductions.Be exactly, the spring force of the pressing member 20 by becoming last pressure is added on the not shown spring force F, firmly remains on the assigned position with output link 15 driving load.Therefore, make and hydraulic pressure takes place draining valve does not firmly cut out with reducing.

In this embodiment, be that the 7d of larger diameter flange portion is set on motor pinion 7, by circle-shaped projection 10d and the circle-shaped projection 12d of third level gear 12 and the position limit (being limited in upper limit position among Fig. 1) that flange part 7d collides and carries out motor pinion 7 that makes first order gear 10, thereby there is no need the special position regulation member that is provided with for motor pinion 7.And, when flange part 7d is set, by needing the position that is provided with of wanting the junction surface 6c of the 6b of portion to form to connect the coupling/decoupling 7a that takes off with first clutch, can reach the position radius and become big, like this, when the position radius that makes coupling/decoupling 7a etc. becomes big, become the situation that the counter-force that is suitable for making solenoid 9 when engaging diminishes.

In addition, be the foregoing description as implementing one of most preferred embodiment of the present invention example, yet, not limited, only otherwise break away from the scope of aim of the present invention, various variant embodiment can be arranged.For example, in the above-described embodiments, be to constitute to have the structure of tooth bar with output link 15 formation driving load, carry out the driving of this member with output pinion 14, yet, also can go up record like that as the real fair 5-17536 of beginning institute's acts conventional case Japan Patent, the structure that employing is taken turns and rope makes up, in addition, also can have tightrope body or flexible flexible body and tooth bar top structure combining as putting down in writing among Fig. 8 of Japanese patent laid-open 2-159942, making.In addition, also can suit to adopt other structure.

For example,, form, it can be installed on the draining valve that moves with wireline operations etc. by being formed on the structure that its top ends is provided with rope even constitute the rack type structures with output link 15 for as above-mentioned embodiment, driving load.Concrete shown in Figure 10 (A), can be formed on and drive upward pass line rope fixer 24 of the load 15c of portion, the structure of stationary rope 26 on this lanyard utensil 24.According to this structure, by intercommunication cross use on the foregoing description shown in lever drive load with output link 15, stretchy rope 26, thereby not limit by the load device shape, same driving load output link 15 can be used, thereby the manufacturing of formula drive unit of the present invention can be efficiently carried out.In addition, shown in Figure 10 (B), also can be formed on the top ends of driving load with output link 15 and lanyard hole 15e is set, the structure of stationary rope 26 on the 15e of this lanyard hole.According to this structure, owing to can save member such as load drive division 15c, so can reduce number of components.

In addition, the technology that is set to the projection 2c that anti-sealing enters from housing cutting part X about the outside at housing 2 also can be applicable to the device beyond the electric driving device shown in the present embodiment, fair 5-17536 of reality that for example can be applicable in the beginning conventional case of lifting or the various electric driving devices that do not contain clutch.In addition, even for driving load is arranged on middle base plate 4 with output link 15 a side respectively, the technology of the opposite side of base plate 4 and
