In addition, be formed at each maintaining part 12a-12d of frame 12 and be formed at the in the form of slot or concavity of maintaining part electromagnetic coil frame 26, that keep each terminal component 23,24, vane type switch 14, connecting elements 17,18 and terminal component 23,24 are embedded just can be securely with its maintenance.
Fix cup-shaped motor field frame 21 in frame 12 bottoms, in this motor field frame 21, accommodating fixing AC motor 13 and the gear train 32 etc. as drive source.Between the iron core 22 in frame 12 and motor field frame 21, near the gear 48 of AC motor 13, supporting axle 28, also supporting axle 39,47,29, and supporting output shaft 44.Output shaft 44 itself can rotate.Rotatably setting-in and gear 48 meshed gears 34 on above-mentioned axle 28, and its below rotatably setting-in folk prescription to limit rod 35.Bar 35 can utilize along with the frictional force of the rotation generation of gear 34 is rotated to the direction of rotation of gear 34.Specifically be in the position shown in Fig. 6 (a), the top ends 35a of bar 35 enter projection 50 on the passage of rotation counterclockwise, stop projection 50 further to rotation counterclockwise, and in the position shown in Fig. 6 (b), the top ends 35a of bar 35 keep out of the way outside the rotating channel of projection 50.This moment, bar 35 was limited rotating range because of its pin 35b is resisted against on the block 68.
The direction of rotation that above-mentioned bar 35 constitutes AC motor 13 is restricted to the direction of rotation limiting mechanism of folk prescription to usefulness, in case AC motor 13 is desired to opposite with certain orientation towards rotation, promptly shown in Fig. 6 (a), the top ends 35a of projection 50 and bar 35 against, because its reaction force, the rotation of AC motor 13 is towards becoming anti-, to certain direction rotation.In case AC motor 13 is to certain direction rotation, one end 35a promptly keeps out of the way to the rotating range of projection 50, allows AC motor 13 to rotate to certain orientation.
Above above-mentioned 28 gear 34, can be provided with gear 37 with rotating freely, more above it, the axis direction of edge axle 28 is provided with the actuating members 92 that gear 37 is pushed movably downwards.Between gear 34 and gear 37, clamping repulsion spring 36.In the bottom of gear 37, be formed with can be chimeric with the embedded hole 34a of gear 34 mosaic process 37a, in the ordinary course of things, because the elastic force of repulsion spring 36, gear 37 is upwards boosted, the embedded hole 34a of mosaic process 37a and gear 34 is separated.Above-mentioned actuating member 92 carries out push operation by the shield 30 that is attracted by electromagnetic coil 25.If electromagnetic coil 25 is energized, shield 30 is attracted, and as shown in Figure 7, actuating member 92 is pushed into, and makes the mosaic process 37a of gear 37 and the embedded hole 34a tabling of gear 34.That is, clutch 27 becomes connection status, and gear 34 is connected with 37.On the other hand, in case the energising of electromagnetic coil 25 is cut off, shield 30 is free state, and repulsion spring 36 is about to gear 37 and upwards boosts, and mosaic process 37a is extracted in embedded hole 34a.That is, gear 34 and 37 is separated, and clutch 27 is dissengaged positions.
In addition, symbol 38 is the friction catch body of speed adjusting gear.Friction catch body 38 is for example formed by rubber etc.Friction catch body 38 as shown in Figure 8, the arm 38c of the circumferencial direction that a pair of arm 38d that have with the hole 38a of the chimeric usefulness of hub portion of gear 40, surround the hub portion 38b of this hole 38a, extends from this hub portion 38b to radial direction, a pair of counterweight 38e of portion that extends to circumferencial direction from this arm 38d and the width that is connected this 38e of counterweight portion and above-mentioned arm 38d are narrow.The 38e of counterweight portion of friction catch body 38 is placed on the gear 40, so that it is unlikely to sagging when not rotating.Be formed with not shown bar-shaped holding section on gear 40, engage with two connecting hole 38g of place on being formed at friction catch body 38 by this holding section, friction catch body 38 is integral rotation with gear 40.In case friction catch body 38 is driven in rotation, the 38e of counterweight portion is because centrifugal force and extending from arm 38c, the top peripheral part 38f of the 38e of counterweight portion promptly with the inwall sliding-contact of friction wall 46.
At this, when 13 actions of AC motor, when driving torque the transmission of output shaft 44 sides from gear 48 side direction, because the friction catch body 38 of Fig. 8 is the rotation of the direction of arrow shown in the solid line in figure, so, even each 38e of counterweight portion extends, the direction sliding-contact that each top peripheral part 38f also is easy to slide to the inwall to friction wall 46 is not so can apply very big brake force for the rotation of AC motor 13.In contrast, when AC motor 13 stops, during from output shaft 44 side direction gears 48 sides transmission driving torque, because friction catch body 38 is the rotation of the direction of arrow shown in the dotted line in figure, so, the relative friction wall 46 of each top peripheral part 38f has very big brake force to work to the direction sliding-contact of nipping, and makes the rotation of output shaft 44 slower.
Then to for example action during as the actuator of the shutter of ventilation fan with this gearmotor.
Figure 1 shows that the off-state of vane type switch, as hereinafter described, is the shutter of the ventilation fan figure when keeping open mode.Then, ventilation fan is carried out opening operation, is not supplied between each connecting elements 17,18 in the A-stage of alternating current, and cam 11 begins rotation from position shown in Figure 1, and cam 11 makes vane type switch 14 be closure state.
Under this state, if being carried out the conducting operation, ventilation fan supplies with alternating current, by respectively giving electric components 15,16, alternating current is supplied between each connecting elements 17,18,13 entrys into service of AC motor.At this moment, desire to the direction rotation opposite, promptly as mentioned above as if AC motor 13 with certain orientation, the top ends 35a of engaging protrusion 50 and bar 35 against, because its reaction force, 13 upsets of AC motor continue later on to regular direction rotation for to regular direction of rotation rotation.
In addition, in case flow through alternating current between each connecting elements 17,18, electromagnetic coil 25 promptly attracts shield 30, and clutch 27 is operated, and makes it become connection status.Thus, the revolving force of AC motor 13 is 32 to pass to output shaft 44 by said gear, and output shaft 44 is driven and rotates, and the shutter of ventilation fan is opened.At this moment, friction catch body 38 also rotates, but the rotation of AC motor 13 that is delivered to friction catch body 38 is owing to gear train 32 is decelerated, friction catch body 38 is with lower speed rotation, so each top peripheral part 38f not too extends, again because its direction of rotation also is the direction shown in the solid arrow of Fig. 8, so the friction load that produces between friction catch body 38 and the friction wall 46 is minimum.Therefore, can easily shutter be opened.
In addition, because the rotation of output shaft 44, cam 11 also rotates.So, in case the shutter of ventilation fan is opened to certain position, promptly as shown in Figure 1, terminal 14a of vane type switch 14 and cam slide position contacting arrive the recess 11a of cam 11, a terminal 14a of vane type switch 14 leaves another terminal 14b, and the alternating current that AC motor 13 is supplied with is cut off.Therefore, AC motor 13 stops.But, at this state, the energising of electromagnetic coil 25 is still continued, so clutch 27 is kept connection status, output shaft 44 and AC motor 13 are owing to gear train 32 links to each other then.This gear train 32 is the speed increasing gear train from output shaft 44 sides to the AC motor side, and being delivered to the power that the shutter of the ventilation fan of AC motor desires to close because of deadweight or spring force etc. can be less.Therefore, only owing to the braking moment of AC motor, the shutter of ventilation fan just can be held open state.Even the masterpiece bigger than the braking moment of AC motor is used for output shaft 44, the reverse rotation of gear 34 is also stoped by bar 35, so output shaft 44 can not reverse rotation, and the state that ventilation fan still is being held open.
In case ventilation fan is made shutoff operation, the alternating current of supplying with between each connecting elements 17,18 just is cut off, so the energising of electromagnetic coil 25 is stopped, clutch 27 becomes dissengaged positions, and output shaft 44 no longer is connected with AC motor 13.Therefore, output shaft 44 just may dally (counter-rotating), and the shutter of ventilation fan is closed automatically because of deadweight or spring force etc.At this moment, the idle running of output shaft 44 is easier to pass to the friction catch body 38 of the speed adjusting gear of being located at output shaft 44 sides than gear 37.As mentioned above, gear train is seen as speed increasing gear train from output shaft 44 sides, and therefore, the rotation of output shaft 44 is passed to friction catch body 38 by speedup.Therefore, friction catch body 38 is subjected to big action of centrifugal force, each top peripheral part 38f from each arm 38c outwards expansion and with friction wall 46 sliding-contacts, and this moment friction catch body 38 direction of rotation shown in the dotted arrow of Fig. 8, be that each top peripheral part 38f embeds the direction in the friction wall 46, therefore can effectively produce brake force.Like this, if output shaft 44 is desired rotation at a high speed, brake force promptly works, and the rotary speed of output shaft 44 is certain speed by basic controlling, and the shutter of ventilation fan is slowly undisturbedly closed.On the other hand, if the rotary speed of output shaft 44 is lower than certain speed, then the centrifugal force that produced of friction catch body 38 is also little, and each top peripheral part 38f leaves friction wall 46, no longer has brake force, so the shutter of ventilation fan can not stop halfway.
Along with output shaft 44 reverses, also towards the original position rotation, a terminal 14a of vane type switch 14 is by being pressed on another terminal 14b for cam 11, and vane type switch 14 is conducting state.And in case the shutter of ventilation fan is closed fully, the counter-rotating of output shaft 44 also stops, and this gearmotor returns to the A-stage after the vane type switch is energized.
In the switching mechanism 1 that is assembled into this gearmotor, be welded on each connecting elements 17,18 respectively for electric components 15,16, be provided with the portion 19,20 that is provided with of extending, but link to each other then, so do not use printing distributing board just can power to AC motor 13 and electromagnetic coil 25 with terminal 14a and each terminal component 23,24 conductings ground of vane type switch 14.Therefore, manufacturing process needn't be increased and just above-mentioned each problem can be solved because of using printing distributing board to cause.In addition, because respectively give on each connecting elements 17,18 in the groove that electric components 15,16 is welded in chimeric each connecting elements maintaining part 12c, the 12d that remains on frame 12, and by frame 12 and cover cap 2 clampings, so, even from the outside to applying excessive load respectively for electric components 15,16, also can be when not using printing distributing board, have influence on coil, terminal 14a, the 14b etc. of AC motor 13, electromagnetic coil 25, can prevent the problem of broken string etc.
In addition, above-mentioned form is one of the preferable form of a utility model example, but not limit by this, can do all changes back and implement in the scope that does not break away from the utility model main points.For example, in the above description, give electric components the 15, the 16th, coat the insulated conductor of ethene, but not limit by this, also can be formed with on the lead top terminal the terminal formula give electric components.
In addition,, but also can not use terminal component 23,24, replace to wait the electromagnetic coil terminal directly is connected to electric components 15,16, extends and be provided with in the portion 19,20 etc. by welding to implementing by terminal component 23,24 of electromagnetic coil 25 to electricity.
Have, in the above description, the actuator as the used in air exchange fan shutter has been assembled into gearmotor with switching mechanism, but self-evident again, and switching mechanism of the present utility model is not limited to the actuator as the used in air exchange fan shutter.
As mentioned above, the application's switching mechanism has frame, cam, drive the drive source of this cam, the vane type switch that conducting disconnects with the cam surface sliding-contact of cam and be connected the connecting elements of giving electric components, vane type switch maintaining part by frame keeps the vane type switch, and keep connecting elements by the connecting elements maintaining part of frame, on vane type switch or connecting elements, form the portion that is provided with of extending, utilizing this extension that portion is set can be connected the vane type switch with connecting elements with switching on, so, do not use printing distributing board just can will be connected on the switching mechanism to electric components from power supply is extended.So the variety of issue that produces in the time of solving above-mentioned use printing distributing board can improve the production efficiency of the switching mechanism that is applicable to gearmotor and reduce and produces cost.
