Though automatically-controlled door is popularized rapidly in each place in recent years, existing problem is how to guarantee the problem that the space is set of this drive source for the setting of automatically-controlled door.Must take in the drive source of having guaranteed following torque capacity in that can guarantee, limited being provided with in the space conversely speaking,, this torque capacity is the torque capacity that drives the door of corresponding weight with corresponding speed.This problem, particularly particularly outstanding when existing manually operated door is replaced by automatically-controlled door, in this respect, drive source in the past may not be a kind of formation of compactness.
In addition, recently, the fairness of the switching of when action (automatically-controlled door non-) when the problem of being paid close attention to is power-off.In recent years, though the exploitation of magnetic material is also improving, and developed than motor in the past little and that efficient is high, but this high-efficiency electric motor is when having a power failure or the step switch of automatically-controlled door when pass through hand switch because of a little reason when closing etc., and (with the common door comparison of the drive source that does not possess automatically-controlled door) exists the problem that switch is required great effort very much.
Summary of the invention
The present invention finishes in order to solve such problem in the past, its purpose be to provide can restraining device maximization the time, the drive source of the automatically-controlled door of the load of the switch in the time of can also alleviating the non-action of automatically-controlled door.
The present invention is the drive source that is used for the automatically-controlled door of automatically-controlled door driving, has solved above-mentioned problem by following structure, and this structure possesses: drive source output shaft, output rotation output; Rotor yoke, concentric with this drive source output shaft, and integrated with this drive source output shaft; Permanent magnet, concentric with this rotor yoke, and integrated with this rotor yoke; A plurality of armature winding, concentric with this permanent magnet, and opposed on radial direction with this permanent magnet, can dispose with the relative rotation in a circumferential direction, on same radius, do not have magnetic material and be wound in flat; And, stator yoke, concentric with this armature winding, and integrated with this armature winding.
According to the present invention, stator yoke can be made simple drum, and thickness that can the Control Radius direction can be relatively with the amount of the gap between rotor and the stator to this segment thickness of radial direction outside expansion of drive source output shaft.Promptly, owing to the axle center of drive source output shaft is left in the generation position of the magnetic force that makes the rotation of drive source output shaft, even if therefore also also can not guarantee to make the rotating torques of drive source output shaft rotation greatly with magnetic materials such as iron cores.In addition, can also increase the surface area of permanent magnet or armature winding etc., the surface area of this permanent magnet or armature winding etc. produces the magnetic force that is used to make the rotation of drive source output shaft.Like this, identical with the external diameter of for example housing and export identical gear motor and compare, the axial length of rotor or stator can be shortened the amount of this segment thickness.
And when having this advantage, the stator yoke that the present invention relates to is simple drum (not having so-called tooth (groove)), and armature winding does not have magnetic materials such as iron core on same radius, and is wound in flat.Therefore, when the non-action of automatically-controlled door, the switching resistance when manually opening and closing automatically-controlled door reduces greatly, and can produce pulsation sense (back will be described in detail) hardly.In order to alleviate the automatically-controlled door switching load in non-when action, often the method for using is to lay clutch mechanism on any one of the power transfer path that drives automatically-controlled door, to avoid arriving the driving source from the transmission of power of automatic reveal, but just clutch mechanism and original power-transmission system need be disposed respectively, the size that will be attended by device self like this increases, installs the bigger shortcoming that the degree of freedom reduces and so on for this reason.In addition, very numerous and diverse by the releasing of manually carrying out this clutch, and can't eliminate numerous and diverse property of the main power source that opens and closes automatically-controlled door.According to the present invention, do not use clutch mechanism etc., the result is, even if power supply also can make automatically-controlled door move, thereby can obtain the drive source of automatically-controlled door very easy to use in off position down by littler power.
In addition, though the relative rotation with armature winding of permanent magnet, wherein either party is configured in the rotor yoke side or the stator yoke side can both realize aim of the present invention.That is, the present invention can take following a kind of form, and promptly a kind of drive source of automatically-controlled door of the driving that is used for automatically-controlled door is characterized in that possessing: drive source output shaft, output rotation output; The rotor yoke of drum, concentric with this drive source output shaft, and integrated with this drive source output shaft; Armature winding, concentric with this rotor yoke, and on same radius, do not have magnetic material, and be wound in flat, thus integrated with this rotor yoke; Permanent magnet, concentric with this armature winding, and opposed on radial direction with this armature winding, can dispose with the relative rotation in a circumferential direction; And, stator yoke, concentric with this permanent magnet, and integrated with this permanent magnet.

Outside the radial direction of permanent magnet 144, dispose the coil holder 149 of approximate cylinder shape, between the jut of giving prominence to the radial direction outside of this coil holder 149, be fixed with a plurality of armature winding 142 via specified gap G1.Promptly, armature winding 142 is configured to: (via coil holder 149) is opposed at radial direction with this permanent magnet 144, and can rotate relatively in a circumferential direction with this permanent magnet 144.Armature winding 142 is fixed on the stator yoke 148.Stator yoke 148 is around the inner peripheral surface side that circumferentially is arranged on above-mentioned drive source housing body 122b.
At this, drive source housing body 122b is a drum, and stator yoke 148 also is simple drum and does not have such in the past tooth (groove).In addition, self integral body of each armature winding 142 applies (molding) by insulative resin, and is wound in hollow and flat.That is, with armature winding 142 same radiuses on do not dispose magnetic materials such as iron core.
In addition, the axial length in the interior week of armature winding 142 (internal diameter) d1 is set at shorter than the axial length W1 of stator yoke 148.And the axial length d1 in the interior week of armature winding 142 is set at shorter than the axial length W2 of this rotor yoke 140.Constituted " stator (fixture) " by stator yoke 148 and armature winding 142.
Be formed with hypoid pinion 112 in the direct cutting of the front end of above-mentioned drive source output shaft 104.Promptly, drive source output shaft 104 forms as one with the power shaft of decelerator 130, and the input pinion of decelerator 130 is that hypoid pinion 112 is also integrally formed with this drive source output shaft 104.This hypoid pinion 112 meshes with the hypoid gear 116 of decelerator 130.This hypoid gear 116 is being provided with fixing with the mode of reducer output shaft 114 one rotation.In addition, reducer output shaft 114 can be rotated to support on the reducing gearbox phosphor bodies 120a via bearing 106.And, can be rotated to support on the output shaft-cup 120b via bearing 108.Output shaft-cup 120b is provided with by bolt 132 and is fixed on the reducing gearbox phosphor bodies 120a.The part that this output shaft-cup 120b is set to himself is output axle 114 and runs through.In addition, constituted reducer shell 120 by this reducing gearbox phosphor bodies 120a and output shaft-cup 120b.
In addition, in the present embodiment, the protecgulum 122c that constitutes drive source housing 122 is integrally formed with the reducing gearbox phosphor bodies 120a that constitutes reducer shell 120.In addition, symbol the 150, the 152nd, oil sealing.
Then, the effect to the drive source 102 of this automatically-controlled door 303 describes.
If, then be accompanied by the energising meeting and on armature winding 142, produce magnetic field to armature winding 142 energisings.Utilize not shown driver to come control flows suitably to cross the moment, direction and the intensity etc. of the electric current of armature winding 142, and utilize attraction and repulsive interaction between the magnetic field that magnetic field that armature winding 142 produced and permanent magnet 144 had, making permanent magnet 144 is the center rotation with drive source output shaft 104.This rotation is transmitted to drive source output shaft 104 via rotor yoke 140, these drive source output shaft 104 rotations.The rotation of drive source output shaft 104 makes hypoid pinion 112 rotations that are formed at these drive source output shaft 104 front ends, and transmits to the hypoid gear 116 with these hypoid pinion 112 engagements.By the engagement of this hypoid pinion 112 with hypoid gear 116, the rotational delay of drive source output shaft 104 is also transmitted to reducer output shaft 114.In addition, be transformed to the direction of quadrature by this engagement direction of rotation.
As shown in Figure 4, because reducer output shaft 114 cooperates with belt wheel 302, so belt wheel 302 is accompanied by the rotation of this reducer output shaft 114 and rotates.By the rotation of belt wheel 302,301 rotations of door rotating band are moved, thereby make the automatically-controlled door 303 that is linked on the rotating band 301 carry out switch.
In the present embodiment, armature winding 142 is made the shape that is wound in hollow and flat, be fixed with the stator yoke 148 of drum in its radial direction outside.
Thus, can obtain following effect.
One of them effect is the fairness the during power-off of the drive source 102 of automatically-controlled door 303 (time) this automatically-controlled door 303 of switch in non-when action.
Present embodiment and the counter-rotating torque of example (Fig. 6 before, the example of Fig. 7) in the past in Fig. 5, have relatively been represented.In Fig. 5, quiet counter-rotating torque (detent torque of the needs during beginning switch automatically-controlled door) ST1 of (during power-off) when being the non-action of drive source 102 of the automatically-controlled door that relates to of present embodiment (A), (B) be the moving counter-rotating torque under the same situation (door begin to move after, be used for continuing this slip torque of moving) DT1.In addition, (C), (D) is respectively quiet counter-rotating torque ST2 and the moving counter-rotating torque DT2 with the drive source 202 of the corresponding automatically-controlled door in the past of (A), (B).
As can be seen from Figure 5, (switch tight preceding) maximum ST2m of the quiet counter-rotating torque ST2 of the drive source 202 of the automatically-controlled door in (switch tight before) maximum ST1m of the quiet counter-rotating torque ST1 of the drive source 102 of the automatically-controlled door that present embodiment relates to and the example in the past compares, and has been reduced to about below 1/3.In addition, the mean value DT1a of the moving counter-rotating torque DT1 of the drive source 102 of the automatically-controlled door that relates to of present embodiment compare with the mean value DT2a of the quiet counter-rotating torque DT2 of the drive source 202 of the automatically-controlled door of example in the past be reduced to about below 1/2.5.
Second effect is to eliminate pulsating torque.
As Fig. 5 (D) as can be known, in moving counter-rotating torque DT2 in the past, produced violent pulsation (so-called cogging torque).This pulsating torque can never appear on (beyond the automatically-controlled door) common door.Therefore, the people of switch door perceives simply because this is an automatically-controlled door and therefore has the torque sense, also can therefore feel that more consumingly the switch torque " increases " (the weight sense of going up) at heart.By the chart of Fig. 5 (B) as can be known, in the moving counter-rotating torque DT1 that present embodiment relates to, almost can't see this pulsating torque.That is to say, in the present embodiment, the value self of quiet counter-rotating torque ST1, the moving counter-rotating torque DT1 value than quiet counter-rotating torque ST2 in the past, moving counter-rotating torque DT2 respectively is little, and the pulsation of moving counter-rotating torque DT1 does not almost have, therefore can be very smoothly when having a power failure or during power-off and can not feel on weight sense ground switch automatically-controlled door, improved convenience greatly.
The 3rd effect is to realize compactedness.
According to the formation that present embodiment relates to, do not need in the space of the winding armature winding of the inside (tooth portion) of in the past stator yoke self, thereby can control stator yoke 148 from thickness in radial direction.The result is that part of amount of stator yoke 148 attenuation relatively can be departed to the radial direction outside of drive source output shaft 104 again in the gap between " rotor (rotor) " and " stator (fixed body) ".Promptly, be used to make 104 rotations of drive source output shaft revolving force generation position (under the situation of same housing external diameter) from the axle center of drive source output shaft 104 further away from each other, therefore can further increase the rotating torques that can make 104 rotations of drive source output shaft.In addition, the magnetic field that can also increase the permanent magnet 144 that produces the magnetic force make 104 rotations of drive source output shaft or armature winding 142 etc. produces the surface area of mechanism.Like this, the axial length that magnetic field can be produced mechanism shortens the amount of this part.In addition, owing to be the hollow winding, therefore can constitute the axial length d1 in interior week of armature winding 142 shorter than axial length W1, the W2 of rotor yoke 140 or stator yoke 148.Its result, axial length (external diameter) D1 of the periphery of armature winding 142 can be constituted than in the past (drive source 202 of Fig. 6～Fig. 8) short.Promptly, can be with the contraction in length of drive source output shaft 104 self.In addition, even if under situation about so constituting, also can guarantee and the output torque of same degree in the past.
The 4th effect is to avoid the bad generation that caused by heat treatment.
As present embodiment or above-mentioned in the past example, directly cut at the front end of drive source output shaft 104,204 under the situation of structure of hypoid pinion 112,212, drive source output shaft 104,204 does not only play the effect of the revolving force of output drive source 102,202, also has the function of the power shaft (rotating shaft of hypoid pinion 112,212) as decelerator 130,230 concurrently.Therefore on drive source output shaft 104,204, apply the heat treatment of the regulation that should be able to bear the load that produced because of engagement or wearing and tearing, yet because these heat treatments can produce on drive source output shaft 104,204 because heating caused " warpage " etc. are crooked inevitably.Certainly, this crooked meeting makes the rotation instability with the system of the rotation headed by the drive source output shaft 204, and also can produce vibration and noise.Under the situation as the purposes of " switch of automatically-controlled door " and so on, because quietness is had requirement, therefore, the operation of removing this crooked processing (straight-barization) is essential.Particularly, adopt on one side and apply suitable pressure, Yi Bian make a method of rotation (rotation) etc. from the radial direction outside that produces crooked drive source output shaft.Yet this is not that the common machine that is used in any one factory and all has just can be finished, thereby needs expense and time, and in the past, cost improves because this problem makes, the processing time increases.
The parts (drive source output shaft) that apply processing long more (more accurate is, the value of total length of removing the drive source output shaft with the maximum gauge of drive source output shaft is big more), then crooked remarkable more by axle that this heat treatment produced.If from opposite angle, as present embodiment, compare relative short drive source output shaft with diameter (for example if can carry axial length, remove the value of total length of drive source output shaft at for example drive source output shaft below 6.0 if can make maximum gauge with the drive source output shaft), then can reduce reliably and follow the crooked of heat treated drive source output shaft.If can reduce to follow the crooked of heat treated drive source output shaft, then can simplify (maybe can omit) and be used to remove crooked processing (straight-bar processing), can reduce cost more, and can keep quietness.
In addition, in the above-described embodiment,, for the purpose of the present invention, do not need certain pinion to be integrally formed on the drive source output shaft with decelerator though hypoid pinion directly is formed on the drive source output shaft.In addition, the kind of pinion also not necessarily is defined as hypoid pinion, for example also can be spur pinion, oblique pinion etc.The kind of decelerator also is not limited to above-mentioned formation.
In addition, though the relative rotation with armature winding of permanent magnet even if wherein any one is configured in rotor yoke side or stator yoke side, also can realize aim of the present invention.Promptly, the present invention is the drive source that is used for the automatically-controlled door that automatically-controlled door drives, it is implemented as following formation, this formation possesses: drive source output shaft, output rotation output; The rotor yoke of drum, concentric with this drive source output shaft, and integrated with this drive source output shaft; Armature winding, concentric with this rotor yoke, and on same radius, do not have magnetic material, and be wound in flat, thus integrated with this rotor yoke; Permanent magnet, concentric with this armature winding, and opposed on radial direction with this armature winding, can dispose with the relative rotation in a circumferential direction; And, stator yoke, concentric with this permanent magnet, and integrated with this permanent magnet.
