Description
Technical field
The present invention relates to one and add energy device, especially a kind of low-speed energy accumulation device for magnetic motor.
Background technique
The magneto ignition process of existing aircraft is that engine crankshaft drives magneto rotor to rotate through driving gear, in rotary course, magnetic flux in rotor magnetic steel and soft iron changes, the primary air be wound on soft iron is caused to produce induction electromotive force, primary circuit produces induction current, and when influence electricity flow valuve reaches maximum, contact maker point of contact disconnects primary circuit, now due to the rapid change of magnetic flux, in secondary winding, induce high voltage induction electromotive force.But because rotating speed when motor just starts is very low, magneto ignition energy shortage, if increase the transformer secondary coil number of turn, can cause again magnetogenerator too heavy, so aircraft usually needs to configure separately ground start special ignition coil.
Summary of the invention
The object of this invention is to provide a kind of low-speed energy accumulation device for magnetic motor, make aircraft without the need to independent terrain point fire coil, under low engine speed speed conditions, magnetogenerator namely can normal ignition, guarantees the normal starting of aircraft.
Technological scheme of the present invention is, low-speed energy accumulation device for magnetic motor comprises centrifugal mechanism, spiral spring and housing, described centrifugal mechanism comprises axle sleeve and is arranged on the fixed plate of axle sleeve one end, fixed plate is provided with the identical centrifugal-block of two shapes and centrifugal-block can rotate around installation shaft, centrifugal-block is also provided with return spring, return spring one end and centrifugal-block are fixed, the other end and fixed plate are fixed, described centrifugal-block is provided with ratchet, ratchet really end may be stuck on the fixing pin that described low-speed energy accumulation device for magnetic motor arranges outward, described housing is provided with through hole and two symmetrical projections, axle sleeve is connected with the rotor shaft of magnetogenerator through through hole, the two ends of described spiral spring are fixed with axle sleeve and housing respectively, the protruding fixed plate through centrifugal mechanism and can with the detent contact of centrifugal-block.Described centrifugal mechanism also includes pressing plate, and axle sleeve is provided with step, and the step that pressing plate is arranged on axle sleeve is fixed with fixed plate, and described fixed plate and pressing plate and centrifugal-block are fixed by a rivet.
When this adds energy device busy, driven by engine housing rotates, centrifugal mechanism is driven to rotate by spiral spring again, when rotating to a certain degree, the end of the ratchet on the centrifugal-block on centrifugal mechanism is stuck on a pin of outer installment, centrifugal-block is rotated around installation shaft, until the other end of centrifugal-block blocks after contacting with another centrifugal-block, because centrifugal-block blocks motionless, thus whole centrifugal mechanism is motionless, the rotor shaft of connected magnetogenerator is also motionless, one end stop motion that spiral spring is connected with axle sleeve, and the other end continues motion, spiral spring is made to be out of shape and to realize energy storage, when housing continues to rotate, the projection through fixed plate be arranged on housing encounters the ratchet on centrifugal-block, centrifugal-block rotates around installation shaft, two centrifugal-blocks are made to be separated contact, centrifugal-block is rotated further, thus ratchet and pin are thrown off, moment spring energy release, whole centrifugal mechanism High Rotation Speed, drive magneto shaft rotates, thus generation instantaneous pressure, improve ignition energy.
By design in early stage and adjustment, when motor shaft is rotated and unify firing time, thus achieve effective igniting.
The present invention passes through spring energy-storage, and abrupt release, thus improve the rotating speed of the axle of magnetogenerator when ignition point, thus overcome the problem that when motor just starts, rotating speed is low, making the ignition energy of magnetogenerator sufficient, when not increasing coil turn, achieving effective igniting, structure is simple, and volume is little.
