Description
Technical field
The present invention relates to the fixing devices of magneto, and in particular to applied to the performance test bed of magneto.
Background technology
Magneto is the small-sized alternating current generator that magnetic field is generated using permanent magnet, is the igniting in gasoline engine ignition system
Power supply.Magneto ignition system is made of switch, ignition coil, circuit breaker, capacitor, ignition distributor and safe discharge device etc.,
Its high-voltage electricity simultaneously generates the spark plug for distributing to each cylinder.
Magneto using rotating-magnet, can be divided into monomer-type and flywheel-type by master-plan mostly.Monomer-type is will be upper
It states each component to be integrally formed, on internal combustion engine；Flywheel-type is that magnet is mounted on internal combustion engine flywheel, other each portions
Part is separately mounted on internal combustion engine, is mostly used for single cylinder engine.Magneto breaker is mostly using mechanical contact-type, it is also possible to brilliant
Body tubular type.Some magnetos are also equipped with some additional components.
The most basic operation principle of magneto：Permanent magnet rotates in the core, and the primary coil on iron core induces electricity
Kinetic potential (is known as primary potential), electric current (being known as primary current) is generated when contact breaker points is closed, when contact breaker points is beaten suddenly
When opening, sudden shutting off primary current, secondary coil induces quite high electromotive force (being known as secondary potential), jumps spark plug
Fire.Most strong spark plug sparking in order to obtain, it should obtain maximum secondary potential；Maximum secondary potential in order to obtain breaks
Appliance contact should be closed when primary potential is zero, and when primary potential maximum opens.
In order to be continuously improved or examine the quality of magneto, need magneto being placed on magneto testboard, with
Convenient for testing its performance.In the installment work of existing magneto before testing, need first to place magneto on testboard, and
The screw rod on workbench is made to pass through the through-hole on magneto installing plate, then nut is set on screw rod to one far from testboard
End, then tightening nut, so as to which magneto is fixed on testboard.This mounting means not only lock by step, efficiency is low, and with
It carries out with test job, magneto can generate vibration, this can lead to the spiral shell between nut loosening or damage nut and screw rod
Tooth.
