Abstract
The utility model belongs to the technical field of generators, which is used for solving the problem of unstable voltage supplying of generators of vehicles for agricultural use at present. The utility model adopts a flying hammer centrifugal device and a spring mechanism for automatically regulating the magnetic flux between a rotor and a stator. The magnetic flux of the utility model is weakened when a motor runs with a high speed, and the magnetic flux of the utility model is enhanced when a motor runs with a low speed. The output voltage of the utility model is kept from 12V to 13.5V. The utility model has reliable and simple structure and is especially suitable for being popularized and used in vehicles for agricultural use.
Description
The utility model relates to a kind of automatic voltage regulation magneto alternator that belongs to technical field of generators.
At present, the AC permanent-magnetic generator that agricultural tricycle is used, simple in structure because of it, the excessive technical problem of voltage difference when having high, low speed, car light does not work during promptly little throttle, and large throttle burns out car light often.This situation of driving at night does not see the road surface, and stop lamp and direction indicator lamp do not work, and is the hidden danger that causes traffic accident.Some agricultural vehicle is used silicon rectification generator instead, but this needs the storage battery electricity to go excitation, also needs supporting adjuster, and cost is higher.In addition, bad because of the agricultural vehicle damping performance, the rural area road conditions are not good, add storage battery and can not often in time charge, and are therefore very short in the useful life of rural area storage battery.
The purpose of this utility model is exactly for solving the automatic voltage regulation magneto alternator that disadvantages of background technology provides a kind of suitable rural area to use.
The purpose of this utility model is achieved in that the main stator of the utility model and rotor form, and is with sleeve on armature spindle, is provided with the flyball centrifugal device at an end of sleeve, and the other end of sleeve is provided with spring mechanism on armature spindle.Sleeve and armature spindle rotate synchronously, but can slide along the axis of armature spindle.Be fixed with permanent magnet and the rotor magnetic pole that wraps in the permanent magnet outside in the sleeve stage casing, the rotor magnetic pole outer ring surface is conical, and the Dui Ying magnetic pole of the stator and the power coil that are fixed on the power coil is the annulus cone therewith.The flyball centrifugal device is by fixedly push-plate, slip push-plate and flyball are formed, fixedly push-plate is fixed on the armature spindle, the slip push-plate is fixed on an end of sleeve, and fixedly push-plate and slip push-plate are the indent disc, equally distributed flyball is closed be buckled on the track of establishing in the fixedly push-plate and slip push-plate.Spring mechanism is made up of stage clip, trim ring, adjustment nut and spring base, and trim ring is fixed on an end of stage clip on the sidewall of rotor magnetic pole, and the other end of stage clip withstands on the spring base, and spring base is fixed on the armature spindle by adjusting nut.Flyball is made up of a cross axle and two bearings, and the flyball number is three.
The utility model is compared background technology and had following advantage: the flyball centrifugal device that 1, is provided with makes when the rotor height slowly runs regulates magnetic flux between rotor and stator automatically, and the voltage that generator sends remains on 12V-13.5V; 2, simple in structure, the reliability height, promote the use of in suitable rural area.

Fig. 3 is a slip push-plate cutaway view.
Fig. 4 is fixing push-plate front view.
Fig. 5 is fixing push-plate cutaway view.
Fig. 6 is a flyball structure cutaway view.
The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1,195 rotary speed of diesel engine are 500-2000 rev/min, and generator speed is a times of engine, is 1000-4000 rev/min.Generator speed is 1000 rev/mins during engine idling operation.At this moment, the magnetic poles flux of rotor and stator is a maximum.When rotating speed is elevated to more than 1000 rev/mins, then three of the flyball centrifugal device flyballs 2 are along fixedly push-plate 3 and the slip push-plate 4 inner tracks that are provided with are done directly outwards to move, thereby promoting slip push-plate 4 moves right, because slip push-plate 4 is fixed on the sleeve 5, also just make sleeve 5 move right (sleeve 5 is connected for spline with armature spindle 6) along the axial line of armature spindle 6, at this moment, permanent magnet 9 and the rotor magnetic pole 8 that is fixed on the sleeve 5 together moves right.Because the outer ring surface of rotor magnetic pole 8 and stator power coil 11 inner ring surfaces and magnetic pole of the stator 7 inner ring surfaces are taper, moving right of rotor will make the magnetic flux between stator 10 and rotor weaken, thereby guarantees that the voltage that generator sends can not raise; Answer with this moment, when rotating speed reduces, flyball 2 centrifugal force reduce, axe movement to armature spindle 1, stage clip 13 promotion sleeves 5 and rotor magnetic pole 8 in armature spindle 1 right-hand member setting is moved to the left simultaneously, magnetic flux between stator 10 and rotor strengthens at this moment, thereby guarantees that the voltage that generator sends can not reduce.When load was arranged, the voltage that generator sends was adjusted to 12V-13.5V automatically.The cone gradient of rotor magnetic pole 8 and stator power coil 11 and magnetic pole of the stator 7 is 1: 10.The left end of stage clip 13 is fixed on by trim ring 12 on the sidepiece of rotor magnetic pole 8, and its right-hand member is fixed on the armature spindle 1 by spring base 14 and adjustment nut 15.Armature spindle 1 is provided with spring base positioning spline 17, is provided with stable pin 16 between spring base 14 and adjustment nut 15.The structure of slip push-plate 4 is shown in Fig. 2,3.Fixedly the structure of push-plate 3 is shown in Fig. 4,5.As shown in Figure 6, constitute by a cross axle 18 and two bearings 19 on the flyball.
