Abstract
The utility model relates to a low-speed energy increasing device of a magnetogenerator. The low-speed energy increasing device comprises a centrifugal mechanism, a scroll spring and a shell, wherein the centrifugal mechanism comprises a shaft sleeve and a fixing plate installed at one end of the shaft sleeve, two centrifuging blocks with identical shapes are installed on the fixing plate and can rotate around an installation shaft, pallets are arranged on the centrifuging blocks, a through hole and two symmetrical bulges are arranged on the shell, the shaft sleeve penetrates through the through hole and is connected with the rotor shaft of the magnetogenerator, two ends of the scroll spring are respectively fixed with the shaft sleeve and the shell, and the bulges penetrate through the fixing plate of the centrifugal mechanism and contact the pallets of the centrifuging blocks.According to the utility model, the spring is used for storing energy, so that the rotation rate of the shaft at the ignition moment of the magnetogenerator is improved, the problem of the low rotation rate when the engine is just started is overcome, the ignition energy of the magnetogenerator is enough, the structure is simple and the volume is small.
Description
Technical field
The utility model relates to a kind of ability device that adds, and especially a kind of magnetogenerator low speed adds can device.
Background technique
The magneto ignition process of existing aircraft is that engine crankshaft drives the magneto rotor rotation through driving gear, and in the rotary course, the magnetic flux in rotor magnetic steel and the soft iron changes; The primary air that causes being wound on the soft iron produces induction electromotive force; Primary circuit produces induction current, and when the influence electricity flow valuve reached maximum, the contact maker point of contact broke off primary circuit; This moment is because the rapid variation of magnetic flux induces the high voltage induction electromotive force in secondary winding.But rotating speed is very low when just having started owing to motor, and the magneto ignition energy shortage if increase the transformer secondary output coil turn, can cause magnetogenerator too heavy again, so aircraft usually needs to dispose separately ground start special ignition coil.
Summary of the invention
The purpose of the utility model provides that a kind of magnetogenerator low speed adds can device, makes aircraft need not independent terrain point fire coil, and under the low engine speed speed conditions, magnetogenerator promptly can normal ignition, guarantees the normal starting of aircraft.
The technological scheme of the utility model is, magnetogenerator low speed adds and can comprise centrifugal mechanism, spiral spring and housing by device, and described centrifugal mechanism comprises axle sleeve and is installed in the fixed plate of axle sleeve one end; Identical centrifugal and centrifugal of two shapes is installed on fixed plate can rotate around installation shaft; Also be provided with return spring on centrifugal, return spring one end and centrifugal are fixing, and the other end and fixed plate are fixed; Described centrifugal is provided with ratchet; Ratchet end really may be stuck in described magnetogenerator low speed and adds on can the device outer fixing pin that is provided with, and described housing is provided with two convexities of through hole and symmetry, and axle sleeve passes through hole and is connected with the rotor shaft of magnetogenerator; The two ends of described spiral spring are fixed with axle sleeve and housing respectively, and convexity is passed the fixed plate of centrifugal mechanism and can be contacted with centrifugal ratchet.Described centrifugal mechanism also includes pressing plate, and axle sleeve is provided with step, and pressing plate is installed on the step of axle sleeve and with fixed plate and fixes, and described fixed plate and pressing plate and centrifugal are to fix through a rivet.
When this added the ability device busy, the rotation of engine drives housing drove the centrifugal mechanism rotation through spiral spring, again when rotating to a certain degree; The end of the ratchet on centrifugal on the centrifugal mechanism is stuck on the pin of outer installment, makes centrifugal to block after centrifugal of the centrifugal the other end and another contact around the installation shaft rotation, because centrifugal is blocked motionless; Thereby whole centrifugal mechanism is motionless, and the rotor shaft of connected magnetogenerator is also motionless, the end stop motion that spiral spring is connected with axle sleeve, and the other end continues motion; Make the spiral spring distortion and realize energy storage, when housing continued rotation, the convexity of passing fixed plate that is arranged on the housing was run into the ratchet on centrifugal; Centrifugal makes two centrifugal to separate contact around the installation shaft rotation, and centrifugal is rotated further; Thereby ratchet and pin are thrown off, moment spring energy release, whole centrifugal mechanism high speed rotating; The rotation of drive magneto shaft, thus instantaneous pressure produced, improved ignition energy.
Through early stage design and adjustment, when making the motor shaft rotation with unification firing time, thereby realized effective igniting.
The utility model is through spring energy-storage, and abrupt release, thereby has improved the rotating speed of the axle of magnetogenerator when ignition point; Thereby the low problem of rotating speed when having overcome motor and just having started; Make the ignition energy of magnetogenerator sufficient, under the situation that does not increase coil turn, realized effective igniting; Simple in structure, volume is little.
