To the structure of (3) part, cuticle bag shape approximately as shown in Figure 4.Except that braces, can be shaped on thereafter and pass hanging of belt and mix.A little direct current or an alternator is equipped with in its inside.The front end of this generator is connected with a small gear speed-increasing transmission.All the other partly can put little cutout, pressure governor, flow controller or rectifier, voltage regulator and direct-flow inverter, can also place little storage battery in addition, on the former running rope wheel of the gearbox the other end (20), be wound with two backguys (27) (32), respectively with casing on spring (31) and former running rope wheel rope pulling stroke amplify lever (105) and link to each other, as shown in Figure 5.
For its transmission system of little gearbox as shown in Figure 6, its structure as shown in Figure 7.Former running rope wheel (20) drives a coaxial gear (21) when rotating.Copper bush (22) is outside in this rope sheave and the gear shaft two ends swing frames (106) can be in casing (23) rectangular guide groove slides 5 millimeter as shown in Figure 7 before and after slightly for garden shape box house part has flange.At the two ends of this rope sheave and gear shaft (24) casing outer lower portion suitable position one friction brake wafer (26) by spring (25) impact is arranged respectively.(27) pull strap axle (24) and axle cogs (21) when just changeing when rope sheave (20) is subjected to restrict, because axle (24) is subjected to the pulling force of rope (27) and the rubbing action of friction brake wafer, make this rope sheave (20), rotating in gear (21) and the copper bush of rotating shaft (24) in its two ends swing frame, gear (28) forwards, (29) and (30) pendulum go, cog (21) and its front gear (28) engagement until this axle, and be with gear (28), (29) and till the rotation of (30) and small generators (33), (this moment, the friction brake wafer (26) of spring impact was left at the axle two ends), when relaxing after under rope (27) is capable because of people's step, stepping on, spring (31) just spurs rope sheave (20) to opposite direction, the rotating shaft (24) of rope sheave this moment (20) and the just therefore pulling force and other driven gears (28) that cause by restrict (32) of spring (31) of (21) and axle sleeve (22) that cog thereof, (29) and the thrust that produces such as (30) rotator inertia and the braking action of above-mentioned friction brake wafer (26), original position is got back in counterrotating and swing.When former running rope wheel (20) when being subjected to pulling force again this rope sheave (20) and rotating shaft (24) axle sleeve (22) thereof and same axle cog (21) rotating pendulum again forward, energy is passed to all the other gears and small generators.And the rotor of all the other gears (28) (29) and (30) and small generators (33), then lift the rope sheave rope when lax because of people's pin at rope sheave etc., when being subjected to spring (31) pulling force backspace original position, can continue to rotate forward generating, energy little waste because of rotatory inertia own.The employing of this mechanism also is my original creation, yet there are no or hear in world today machinery industry has employing, but facts have proved that this structure is advanced, simpler than change straight reciprocating motions such as connecting rods into rotational motion mechanism, take up an area of little, become linear reciprocating motion when rotatablely moving, is driven driven members such as driving gear and small generators and rotate and inertia rotates to a direction, thereby the transmission efficiency height.This gear up mechanism adopts secondary overdrive gear speedup except that former running rope is taken turns its rope pulling stroke amplification its in-line gears of lever (105) (21), axle (24), axle sleeve (22) as seen from Figure 7.Every gear-stage velocity ratio is the speed rotation that small generators is changeed with 1000～2000 per minutes.This speed can be satisfied the demand.Module adopts about 1.5 to get final product.Metallurgical bearing (112) of the available powder of second axle of this gear up mechanism or ball bearing (34).The 3rd axle is the axle of small generators, speedup is contained on the small generators axle with small gear get final product.Whole gear box assembly can be mainly by bearing hole being arranged, putting axle sleeve swinging mounting oblong aperture, friction catch flat spring fixing screw hole, rope sheave pulling stroke amplifies the lever fixing screw hole, steel wire backguy and sleeve pipe thereof or gas or hydraulic actuator mounting hole and positioning screw hole thereof, compositions such as casing of tank filler sleeve and oil level peep hole (23) and side cover (35) thereof and casing front cover (36) and sight glass, plug and attaching nut, screw, packing ring are used oil lubricating.For further simplified structure, to simplify and lubricate, back one-level speedup driving gear can replace with rope sheave and rope.This moment, small generators shaft centre line position should be adjustable.
By the described various generators of top described gearbox and back as can be known, it is little that this equipment rotates the part size.Is that example can be regarded as to such an extent that it rotates partly by static when rated speed is arranged with 15 watts of back designs than large equipment, and needing to consume acceleration kinetic energy be 1.4138 kgfms.If 30 kilograms of people underfooting legpower average out to are stepped on down the sole distance when being 0.012 meter, the merit of being done for two to three times is stepped in each time of people's bipod just can make this equipment rotating speed reach rating value.(should be equipped with this moment people walk the variation that successively lands of heel sole).
The DC generator that this equipment adopted is the generator that changes little past automobile.Its main component part has shell, end cap, magnetic pole, armature, carbon brush and gear as shown in Figure 8.The shell of generator (37) is to make the garden barrel shape with mild steel, has four fenestras in the rear end of shell, and its effect is convenient when overhauling carbon brush and rectifier.There are direct current terminal (38) and their equal and casing insulations of magnetic field boundary wiring terminal (39) in the outside of shell, and there are protecgulum (40) and bonnet (41) in the two ends of generator body.Ball bearing (42) and (43) all are housed, with the supporting armature shaft on the front and rear covers.Covering oilhole (44) and (45) in addition, in order to lubricating bearings.The bearing outside goes out to prevent flow of lubricant with the oil sealing sealing.Also be fixed with two brush holders on this external bonnet, it makes carbon brush keep relative position with rectifier.Be separated by with insulation board between cloudy brush holder and lid.And positive brush holder directly links to each other with lid.Front and rear covers passes shell with two standing screws (46) itself and shell (ground wire) is fixed together.For the weight reduction lid is constituted of aluminium.Dustproof hoop (47)---be to make with sheet iron.It is packed on the window of generator casing back with a screw, and window is covered, and invades generator with dust protection.Magnetic pole comprises four pole cores (48).It is screwed the uniform four sides of wall in the enclosure.Pole coil (49) is housed on each iron core.Per two coils are connected mutually, and an end bonding, the other end then link to each other with magnetic field boundary wiring terminal (39) on the shell.Armature is the rotation part of generator.Coil rotates in the magnetic field boundary and produces electric current, and armature comprises armature shaft (50), armature core (51), armature coil (52) and rectifier (53).Armature shaft (50) is that the steel material is made, and is fixed with rectifier on axle, and the spline that has secured core to use.The two ends of axle are contained in the bearing of generator front and rear covers.
Armature core is made up of many shapes silicon steel plate as shown in Figure 9, and the center of silicon steel plate is porose, has opened many grooves around it, in order to place armature coil.It is parallel with axle that groove has, have with axle (oblique) at an angle.The advantage of skewed slot is because when rotating, each coil is to turn to another magnetic pole from a magnetic pole gradually, so pulsation of current reduces, and when certain rotating speed, the peculiar roar of generator can alleviate.Scribble one deck insulated paint on these silicon steel plate surfaces, make each sheet mutual insulating, compress then on the spline that is packed in armature shaft, cellulosic insulating washer is equipped with at the two ends of iron core, and its shape and silicon steel plate are just the same and therewith be fixed on the axle.Armature coil (52) be with cotton covered wire in the groove of iron core, it is divided into some groups, every group the number of turns be about 3～6 the circle, the group number of coil and every group of number of turns how much be to decide according to the pattern of generator.In order to improve the voltage of generator, each two ends of organizing coil is welded on (promptly the not end of first group of coil is welded on the same commutator segment with the origin or beginning of second group of coil) on the rectifier with the order of connecting.Coil is in the groove of iron core, and is all isolated with insulating paper, and scribbles insulated paint on the surface, in case punched by electric current, rectifier (53) is made up of many copper commutator segments.Figure 10 is the sectional drawing of rectifier, and the inside part of commutator segment (54) makes dovetail, is placed in the dowetailed housing joint of lining (55).Commutator segment is clamped on the lining with retaining ring (56) in the commutator segment outside.Between each commutator segment, reach commutator segment and lining, all use mica insulation between retaining ring, lining is pressed on the armature shaft, generator is had four utmost points, and armature coil is with ripple winding coiled, and then the quantity of rectifier copper sheet is that a demultiplication of iron core slot goes one, for example iron core slot has 21 grooves, the commutator segment number is not 42 but 41, and carbon brush (57) and (58) form with compactings such as powdered carbon, red copper, tackiness agents, and its effect is that the electric current that armature coil produces is passed to external circuit.Its device on the negative and positive brush holder, borrows the pressure of spring that itself and rectifier are often kept in touch in the generator bonnet.Anode carbon brush bonding, negative electrode carbon brush then use lead to be connected with electric driving rod (38) on the generator casing, and gear or rope sheave are packed in the front end of armature shaft with key.This kind generator for and swash the formula DC generator.Be that pole coil is in parallel with armature coil.When armature rotated in the magnetic field boundary that magnetic pole produced, armature coil produced induction current because of cutting magnetic line.The sub-fraction of this electric current flows into pole coil for excitation.Most of electric current flows to consuming device then through carbon brush by bonding, flows to armature coil by cloudy carbon brush again.When armature begins to rotate, armature coil by the cutting magnetic pole a small amount of remanent magnetism and produce electric current.
Figure 11 represents the magnetic circuit of direct current generator.Figure 12 has represented the magnetizing force of the closed winding of the magnetic line of force with thick dashed line.
Electric power storage is the same with general automobile DC generator will a little dynamo governor that changes that is sleeved on together for the normal reliable running is generated electricity with the foot-operated generating power supply of this equipment walking.Comprising: cutout, flow controller and three parts of pressure governor.They all are the robots of electromagnet mechanism.Cutout is used for managing automatically the circuit between generator and the storage battery.Flow controller is the maximum current intensity that is used for limiting generator output.Pressure governor then is to be used for the voltage of regulator generator to make it maintain rating number.
(1) cutout, the structure of cutout as shown in figure 13.
When generator armature is static when not changeing, no current passes through in the shunt winding (59), and iron core (60) is not magnetized; When generator armature during with low speed rotation, shunt winding (59) though in have electric current to pass through, because of the magnetic field boundary that it produced makes the magnetized strength of iron core (60), can't overcome the pulling force of spring (61), and the suction lower contact arm, contact (62) still remain on the state that separates with (63).This moment, the circuit of generator and storage battery was not switched on.
When generator speed increased, the terminal voltage of generator also increased thereupon.When generator voltage during greater than the terminal voltage of storage battery, by the magnetic field boundary that electric current produced of shunt winding (59), make the magnetized strength of iron core (60), can overcome the pulling force of spring (61), contact point arm is inhaled down, make contact (62) and (63) closure.This moment, generator and battery circuit were connected.From the electric current of generator output through series winding (64) to electricity consumption part (65), and to charge in batteries.All there is electric current to pass through in shunt winding this moment (59) and the series winding (64).Its current direction is identical, and magnetic line of force direction is also identical.The addition of magnetic field boundary is strengthened the magnetized strength of iron core.Thereby guaranteed that contact (62) is connected with the reliable of (63).
The generator armature rotating speed lowers, and the terminal voltage of generator also reduces thereupon.When generator voltage was lower than the terminal voltage of storage battery, the electric current of storage battery was gone into generator with adverse current, went into generator and discharged through series winding (64) adverse current with the charging opposite current flow direction; The current direction that flows into shunt winding (59) from storage battery still keeps the identical current direction of direction when charging.
This moment, the magnetic field boundary offseted by the current opposite in direction of shunt winding (59) with series winding (64), and the magnetization strength of iron core (60) weakens, and the pulling force of spring (61) is returned to the origin-location with contact arm (66), and contact (62) and (63) are separated.Storage battery and generator circuit are cut off, and storage battery stops the adverse current to generator, no longer discharge.
(2) flow controller, help oscillatory type flow controller such as Figure 14 of the coil that shakes, when the output current of generator through flow controller coil (67), supply with the electric current of external circuit electricity consumption, when not surpassing the scope that is limited, the magnetic force of flow controller iron core this moment (68) can't overcome the pulling force of spring (69), and inhales lower contact arm (70), and contact (71) still remain closed with (72).The additional resistance of not connecting in the field circuit, field current is bigger, and is also big by the electric current that helps the coil that shakes (73), helps the magnetic field boundary that coil produced that shakes also strong, and the magnetic field boundary of it and flow controller coil (67) is strengthened the magnetic force of iron core (68) jointly.Treat the electricity consumption electric current in the external circuit, when increasing to the scope that is limited, flow controller coil (67) and the common magnetic field boundary that helps the coil that shakes (73) to be produced, the magnetic force that iron core (68) is produced can overcome the pulling force of spring (69) and inhale lower contact arm (70), and contact (71) and (72) are separated.Added additional resistance (74) in the field circuit this moment, and exciter current of generator lowers, and then also lowers by the electric current that helps the coil that shakes (73), and the magnetic field boundary weakens.The attenuating of exciter current of generator in addition, also reduced the induction electromotive force of armature coil, the electric current in the external circuit has also been lowered in the reduction of electromotive force, thereby reduce by the electric current of choke coils (67), the magnetic force of iron core (68) weakens thereupon, and the pulling force of spring (69) makes contact (71) and (72) closed again again.(75) be cutout.
So help the interaction energy of the coil that shakes to improve the vibration frequency of contact point arm, quicken separating and closure of contact, make the electric current change in the external circuit less.
(3) pressure governor has oscillatory type pressure governor such as Figure 15 of helping shake resistance and ballast resistor.When pressure governor contact (76) and (77) closure, flow out electric current from the anode carbon brush and be divided into two-way: flow into pole coil once bonding, again (76) and (77) and ballast resistor (78) and flow to the negative electrode carbon brush through the contact.Two flow into pressure governor coil (79) through bonding, again through helping the resistance that shakes (80) to flow to the negative electrode carbon brush with ballast resistor (78).
Have only resistance value little ballast resistor (78) in the field circuit this moment, and field current is bigger, thereby produce bigger voltage drop at the two ends of ballast resistor (78).But have only a spot of electric current of pressure governor coil to pass through on the resistance that shakes (80) helping, thereby the voltage drop that produces is less.But keeping certain voltage drop at the two ends of pressure governor coil like this,, helping the resistance that shakes (80) because the terminal voltage of generator is to equal ballast resistor (78), pressure governor coil (79) three and.
When the armature rotating speed increases, pressure governor contact (76) and (77) are when separating, and the electric current that flows out from the anode carbon brush is divided into two-way: flow into pole coil once bonding, again through additional resistance (81), help the resistance that shakes (80), ballast resistor (78) and flow to the negative electrode carbon brush.Flow into the pressure governor coil once bonding, again through helping the resistance that shakes (80), ballast resistor (78) and flow to the negative electrode carbon brush.
Except that original ballast resistor (78), increased additional resistance (81) again and helped the resistance that shakes (80) in this moment field circuit, the numerical value of resistance increases, and the field current minimizing is fallen in the both end voltage of ballast resistor (78) and to be reduced.Help the both end voltage of the resistance that shakes (80) to fall but increase on the contrary.Because helping the resistance that shakes (80) to go up except that original pressure governor coil current passes through, increased passing through of field current again, thereby voltage drop increases.Voltage drop numerical value helping the resistance two ends that shake to be increased but equals the voltage drop numerical value that the ballast resistor two ends are reduced, and still can keep certain voltage drop at the two ends of pressure governor coil like this.(81) be cutout.
Though the closure of contact with separate, all can keep certain voltage drop, thereby just may keep the constant of generator voltage at the two ends of pressure governor coil.
The adoptable alternator power supply of this equipment system has adopted world's automobile alternator origin system that China progressively adopted in the last few years since the sixties.The generator amature rotating speed can be little like this, can be in wider speed range generating.It is little, in light weight, simple in structure than the DC generator volume in addition, can save copper coin, and is easy to maintenance, long service life.When making it to become motor with storage battery or other powered battery, direct current is powered to small generators into the electronics direct-flow inverter of Ac by becoming direct current, make this alternator become small-sized Wechselstrommotor.
The alternator power supply that this equipment adopts is by three-phase or single phase synchronous generator, silicon rectifier and voltage regulator, (oscillatory type or crystal formula), three partly form, and their Placement is as shown in figure 16, (83) be alternator, (84) are rectifier.(85) be voltage regulator, (86) are ignition switch, and (87) are ammeter, and (88) are storage battery.Alternator when not reaching operating voltage, (promptly when the running of the slow-speed of revolution very), his magnetic field boundary is separate excitation, supplies with the field winding electric current by storage battery, after beginning generating, is self-excitation.In the loop of ignition switch (86) is connected on field winding---regulator---storage battery, when connecting ignition switch, the electricity of storage battery just flows through the generator field winding.Disconnect ignition switch at ordinary times, storage battery can be to generator discharge.(83) be consumer.
The alternator that this equipment adopts structurally, and is different with the salient pole type synchronous alternating-current generator with general industry.As shown in figure 17, (90) are rear end cover for driving end cap (91), and (92) are stator, and (93) are gear or are (94) rope sheave, and (95) are rotor, and (96) are collar, and (97) are slip ring, and (98) are brush holder.Also can install fan (99) when needing additional, excitatory his shape of employing beak shape magnetic pole resembles beak, and as shown in figure 18, this magnetic pole can make the AC electromotive force near sinusoidal curve of stator induction.
The magnetic flux of each magnetic pole is through the iron core of rotor, (being yoke) bout, form the total magnetic flux of generator, total magnetic flux equals the magnetic flux summation of all magnetic poles of polarity, so just can adopt a simple field winding, on the iron core of rotor, compact structure, so only consume a spot of copper cash, the magnetic pole logarithm can be 6 reciprocity a plurality of logarithms.Be that rotor every circuitry phase that circles can produce the interchange electromotive force in 6 week etc.
The end of rotor (95) field winding is connected on the slip ring (97), and this slip ring is contained on the axle of rotor (95).Magnetic pole is to become to reprocess after the basic shape with the low carbon steel plate punching out to form also available microcast process (being lost-wax casting) casting.Every motor has two utmost points, puts field winding in the middle of them.Be fitted in and roll on the dapple axle, after such field winding energising, a pawl utmost point forms the South Pole, and another pawl utmost point forms arctic, and the yoke (iron core) in two pawl utmost point internal surfaces and the field winding must be pasted very tightly.Want evenly in gap between the beak shape magnetic pole of two pawl utmost points, otherwise the magnetic flux that produces in the field winding will produce leakage field in the middle of them, influence generator performance.So during fabrication, the perpendicularity on the perpendicularity of pawl utmost point hole and internal surface and yoke hole and two planes is very important.Yoke also is to be processed into by low carbon steel, is that its magnetic property is good with the purpose of low carbon steel, and the more magnetic line of force is passed through in magnetic pole.
Epitrochanterian slip ring.(also claiming collector ring), form by two copper rings insulated from each other, middle insulating material generally uses fiberglass plastic, slip ring can process with copper pipe, and also the punching out of available copper plate stretching forms, and with fiberglass plastic or other certain mechanical strength is arranged, and after can heat-resisting plastics being pressed into one, be press fit on the axle, this slip ring contacts with two carbon brushes on being contained in the carbon brush end cap, guides to the generator outside with wiring terminal again.
The iron core of stator (92) is to be built up by the silicon steel plate that is D11 or D21 towards the trade mark that groove is arranged, and the thickness of silicon steel plate is 0.5～1 millimeter.The method that builds up of silicon steel plate can adopt welding according to the production technology difference, also can adopt riveted joint.The general stator iron core that builds up with 0.5 millimeter silicon steel plate, need add thickness on two limits is that the steel plate of 2 millimeter is made dististyle, is out of shape preventing.Stator iron core with 1 millimeter silicon chip builds up because rigidity is better, not necessarily need add dististyle, and the groove of stator iron core is laid three-phase or single-phase winding.
When rotor rotated in stator, the N utmost point of rotor and the S utmost point alternately passed through at stator teeth and yoke portion.Three phase windings in stator slot induction alternating electromotive force is the winding distribution map of the general alternator of the three-phase of 36 straight troughs as shown in figure 19 for the q=1 number of stator slots.A, B, C represent the origin or beginning of three phase windings.XYZ represents the not end of three phase windings.Earlier every phase winding is wound separately and put into stator slot again.Any type of stator slot all need insulate with the isolation layer of 0.3～0.5 millimeters thick.The general at present fish paper that adopts.The lead of staor winding and field winding adopts the high-strength polyester enameled cable of the QZ trade mark.After three phase windings are put into stator slot, fix with glass-cloth board or with the slot wedge that bamboo is made, as shown in figure 20.
Rotor field winding, slip ring, pawl extreme pressure install to axle and go up after back and stator three-phase or single-phase winding embed in the stator slot, all need soak insulating varnish, to improve the insulating property of winding, mechanical property and heat dispersion, can use the insulating varnish of 1030 or 1032 trades mark at present, also can be with the insulated paint of other trades mark.
The end cap of generator (90) and (91) are to form by aluminium alloy compression casting or with sand mold casting, because aluminum alloy is a non-magnet material.If leakage field will be arranged with ferrous metal, influence the performance of generator, for the mechanical strength that improves bearing hole increases its wear resistance, can stud with steel bushing at the bearing support of generator ' s cover.These steel bushings should be inlayed in die casting or casting process.Reinforced Nylon or other brush holders that has the plastics of certain mechanical strength to make are housed in the carbon brush end cap.Two spirality pressure springs are housed in the brush holder, push down two carbon brushes such as Figure 17 respectively carbon brush is reliably contacted with slip ring.Intake grill is arranged around the carbon brush end cap when needing, drive be stamped exhaust outlet small gear (93) with fan (99) just make when rotating air from the rear end cover air intake through motor internal from the air-out of driving end cap, the staor winding of cooled electric generator.Fan generally is with punching of the steel plate or uses aluminium alloy compression casting.Gear can be made with the 45# steel.
The alternating current of responding in the alternator frame winding, the rectifier that rely on silicon cell to form is changed into direct current.Can use single-phase full-wave rectifer circuit to small-sized single-phase generator, also available as shown in figure 21 single phase bridge type rectifier circu carries out rectification as shown in figure 22 to threephase alternator, and available three-phase bridge rectifier circuit carries out rectification as shown in figure 23.
At present with the alternator cooperating, make the voltage of generator when different rotating speeds, remain on the voltage regulator of certain numerical value, can adopt generally employing to change little twin-stage electromagnetic regulator shown in Figure 24.Its working principle is, before engine start, connects ignition switch earlier, and this moment, the electricity of storage battery was just sent to the generator field winding by regulator contact (102) (103), and current direction is as deceiving shown in the arrow among Figure 24.Electric current is also by regulator coil (104) simultaneously.Behind generator starting, the rotating speed of generator increases, and electric current and then increases in the regulator coil (104), and electromagnetic attraction strengthens, and armature is further inhaled to iron core on one side, starts working in second pair of contact.By in the circuit as can be seen, the second pair of contact is with the field winding short circuit of generator.After second pair of make contact, field winding loses voltage, the very fast decline of exciting curent, and the voltage of generator also just descends rapidly, and voltage has descended, and the electromagnetic attraction of regulator core is less than spring tension, and just open second pair of contact.Field winding obtains voltage again, and exciting curent rises again, and voltage increases again, and second pair of contact is closed again.The contact is just closed and open with a certain frequency period ground, makes generator output voltage remain on specified value.
Make it to become motor in order to import generator with the electricity of storage battery conversely, make the foot-operated generating of this walking power supply machine become the walk help machine, make it to become motor can directly direct current being imported generator with the equipment of DC generator.To the equipment with alternator then need make direct current earlier the series inductance formula controllable silicon three-phase inverter by as shown in figure 25 become alternating current, import generator again and make it to become motor.Wherein major loop as shown in figure 26.In inverter A circuitry phase, controllable silicon SCR
